SECURISATION SECURING
DOMAINE TECHNIQUE TECHNICAL AREA
La présente invention concerne le domaine technique général des unités de refroidissement, et plus particulièrement des groupes froids équipant des bâtiments industriels, d’habitation, commerciaux, etc. The present invention relates to the general technical field of cooling units, and more particularly to cold units equipping industrial, residential, commercial buildings, etc.
La présente invention concerne plus précisément un ensemble de refroidissement comprenant un groupe froid équipant un bâtiment, ledit groupe froid comprenant un système de refroidissement ainsi qu’un châssis renfermant ledit système de refroidissement, ledit châssis comprenant une surface supérieure externe sensiblement horizontale formant une plate-forme sur laquelle un opérateur peut se tenir pour procéder à une intervention de maintenance dudit groupe froid. The present invention relates more precisely to a cooling assembly comprising a cold unit equipping a building, said cold unit comprising a cooling system and a frame enclosing said cooling system, said frame comprising a substantially horizontal outer upper surface forming a platform. shape on which an operator can stand to carry out a maintenance intervention on said cold unit.
La présente invention concerne également un procédé de sécurisation d’un groupe froid. The present invention also relates to a method for securing a cold unit.
La présente invention concerne en outre un kit de sécurisation des interventions sur un groupe froid. The present invention also relates to a kit for securing interventions on a cold unit.
TECHNIQUE ANTERIEURE PRIOR TECHNIQUE
Il est connu d’installer des groupes froids pour équiper des bâtiments. Ces groupes froids fournissent généralement au bâtiment ou à une unité industrielle située au sein ou en annexe du bâtiment un fluide refroidi, permettant d’établir par exemple un circuit de climatisation, de réaliser une chambre froide, etc. Ces groupes froids se présentent individuellement sous la forme d’un bâti fixe massif de plusieurs mètres de long, de large et de haut, en forme de parallélépipède rectangle, renfermant une unité de refroidissement. It is known to install cold units to equip buildings. These cold units generally supply the building or an industrial unit located within or annexed to the building with a cooled fluid, making it possible, for example, to establish an air conditioning circuit, to create a cold room, etc. These cold units come individually in the form of a solid fixed frame several meters long, wide and high, in the shape of a rectangular parallelepiped, enclosing a cooling unit.
Il est également connu de procéder à des interventions de maintenance de ces groupes froids, notamment au niveau de leurs parties supérieures. En effet, ces groupes froids présentent généralement des éléments mécaniques à entretenir situés au niveau de la partie supérieure du bâti. Un opérateur intervient ainsi régulièrement sur la partie supérieure du groupe froid en escaladant ce dernier avec une échelle, de façon à se tenir sur une plate-forme de la partie supérieure, afin par exemple de nettoyer avec une lance à haute pression des éléments mécaniques tels que des organes de ventilation. It is also known to carry out maintenance operations on these cold units, in particular at their upper parts. In fact, these cold units generally have mechanical elements to be maintained located at the level of the upper part of the frame. An operator thus intervenes regularly on the part unit by climbing the latter with a ladder, so as to stand on a platform of the upper part, in order for example to clean with a high pressure lance mechanical elements such as ventilation units.
Or, les méthodes connues d’intervention des opérateurs de maintenance sur les groupes froids ne sont pas totalement satisfaisantes. However, the known methods of intervention by maintenance operators on cold units are not completely satisfactory.
En effet, lors d’une intervention sur la plate-forme, l’opérateur se retrouve souvent juché à une hauteur significative, qui est celle du groupe froid, pouvant aller jusqu’à plusieurs mètres au-dessus du sol, et par exemple comprise entre 1 ,5 et 4 mètres. Il existe donc un risque corporel si l’opérateur chute au sol. Il existe également un risque pour les personnes susceptibles d’évoluer aux alentours du groupe froid, au pied de ce dernier, en cas de chute accidentelle de matériel de maintenance (tournevis, etc.) utilisé par l’opérateur. Le danger est particulièrement élevé dans le cas où le groupe froid est positionné sur un bâtiment présentant une hauteur importante, l’opérateur ou son équipement pouvant potentiellement chuter de plusieurs dizaines de mètres, ce qui présente de surcroît un risque considérable pour les personnes et les biens situés en- dessous. De plus, même lorsque l’équipement tombé est resté intact et n’a blessé personne, l’opérateur doit encore aller le chercher en redescendant via l’échelle posée contre le groupe froid, augmentant de ce fait le risque d’accident de personne, et perdant de la sorte un temps précieux, rallongeant ainsi la durée prévue de maintenance. Indeed, during an intervention on the platform, the operator often finds himself perched at a significant height, which is that of the cooling unit, which can go up to several meters above the ground, and for example included between 1, 5 and 4 meters. There is therefore a personal risk if the operator falls to the ground. There is also a risk for people likely to move around the cooling unit, at the foot of it, in the event of an accidental fall of maintenance equipment (screwdriver, etc.) used by the operator. The danger is particularly high in the event that the chiller is positioned on a building with a great height, the operator or his equipment could potentially fall several tens of meters, which also presents a considerable risk for people and operators. goods located below. In addition, even when the fallen equipment has remained intact and has not injured anyone, the operator must still retrieve it by descending via the ladder placed against the chiller, thereby increasing the risk of personal accident. , and thus losing precious time, thus extending the scheduled maintenance time.
Afin de limiter les risques exposés ci-dessus, il est connu de recourir à des dispositifs de sécurité pour garantir la sécurité des opérateurs et de leur équipement lorsqu’ils sont sur une plate-forme supérieure d’un groupe froid. Ces équipements doivent satisfaire aux exigences de normes concernant la sécurisation des équipements et des personnes au travail qui requièrent des conditions de sécurité optimales pour autoriser les opérateurs à travailler en hauteur sur des groupes froids. Or, ces dispositifs connus censés garantir la sécurité des opérateurs de groupes froids et satisfaire les normes de sécurité relatives, bien qu’ils remplissent globalement leurs fonctions, ne sont pas totalement satisfaisants non seulement d’un point de vue pratique mais également en termes de sécurité. En effet, les dispositifs de sécurité pour groupes froids connus imposent le montage long, complexe et sujet à erreur de lignes de vie ou cordages, auxquel(le)s sont rattachés les opérateurs, les lignes de vie étant elles-mêmes reliées à un point de fixation situé sur la plate-forme ou rattaché à cette dernière. Les équipements des opérateurs ne sont souvent pas assurés ou seulement attachés via des filins aux opérateurs ou au point de fixation. Ces multiples fixations et lignes de vie présentent une mise en place longue, complexe et peu pratique pour les opérateurs, ces derniers devant faire évoluer leurs équipements et se déplacer eux-mêmes entre les lignes de vie, ce qui rend les opérations de maintenance longues et fastidieuses. In order to limit the risks exposed above, it is known practice to resort to safety devices to guarantee the safety of the operators and their equipment when they are on an upper platform of a refrigeration unit. This equipment must meet the requirements of standards concerning the safety of equipment and people at work which require optimal safety conditions to allow operators to work at height on cold units. However, these known devices supposed to guarantee the safety of cold unit operators and meet the relative safety standards, although they generally fulfill their functions, are not totally satisfactory not only from a practical point of view but also in terms of security. Indeed, the safety devices for known cold groups require the long, complex and error-prone assembly of lifelines or ropes, to which the operators are attached, the lifelines themselves being connected to a point. fixing located on the platform or attached to it. Operators' equipment is often uninsured or only attached via ropes to operators or to the attachment point. These multiple fixings and lifelines present a long, complex and impractical installation for the operators, the latter having to upgrade their equipment and move themselves between the lifelines, which makes maintenance operations long and difficult. tedious.

MEILLEURE MANIERE DE REALISER L’INVENTION BEST WAY TO MAKE THE INVENTION
L’invention concerne, selon un premier aspect illustré aux figures, un ensemble de refroidissement sécurisé 1 comprenant un groupe froid 2 équipant un bâtiment. Ainsi, ledit ensemble de refroidissement 1 est préférentiellement conçu pour équiper un bâtiment, c’est-à-dire notamment une structure fixe de type construction immobilière, par exemple destinée à former une habitation, un immeuble de commerce, industriel ou de bureau, etc. De préférence, ni l’ensemble de refroidissement 1 ni le groupe froid 2 n’est conçu pour équiper un véhicule, bien que cette possibilité ne soit pas totalement exclue, le bâtiment pouvant alternativement être formé par un gros véhicule présentant des dimensions (et donc des contraintes) comparables à celles d’un immeuble, le gros véhicule étant par exemple un navire d’une certaine dimension équipé dudit groupe froid 2, le terme « bâtiment » devant dans ce cas précis être compris comme synonyme de « navire », de préférence de grande taille (type paquebot par exemple). The invention relates, according to a first aspect illustrated in the figures, to a secure cooling assembly 1 comprising a cold unit 2 fitted to a building. Thus, said cooling assembly 1 is preferably designed to equip a building, that is to say in particular a fixed structure of the real estate construction type, for example intended to form a dwelling, a commercial, industrial or office building, etc. . Preferably, neither the cooling unit 1 nor the cold unit 2 is designed to equip a vehicle, although this possibility is not completely excluded, the building possibly being alternatively formed by a large vehicle having dimensions (and therefore constraints) comparable to those of a building, the large vehicle being for example a ship of a certain size equipped with said cold unit 2, the term "building" in this specific case to be understood as a synonym of "ship", preferably large (liner type for example).
Ledit groupe froid 2 présente préférentiellement, comme cela est connu, une forme générale de parallélépipède rectangle, c’est-à-dire de pavé droit, et présente en particulier des dimensions extérieures relativement grandes. Par exemple ledit groupe froid 2 présente des dimensions comprises entre 1 ,5 et 5 m de largeur, entre 2,5 et 10 m de longueur, et entre 1 ,5 et 5 m de hauteur. Said cold unit 2 preferably has, as is known, the general shape of a rectangular parallelepiped, that is to say of a straight block, and in particular has relatively large external dimensions. For example, said cold unit 2 has dimensions of between 1, 5 and 5 m in width, between 2.5 and 10 m in length, and between 1, 5 and 5 m in height.
Selon l’invention, ledit groupe froid 2 comprend un système de refroidissement 3 ainsi qu’un châssis 4 renfermant ledit système de refroidissement 3. Ledit système de refroidissement 3 comprend par exemple une ou plusieurs machines thermodynamiques, qui peuvent être conçue(s) pour fournir un fluide refroidi audit bâtiment ou à une unité industrielle attenante audit bâtiment ou située au sein de ce dernier (l’unité industrielle pouvant éventuellement constituer le bâtiment en tant que tel), de façon à réaliser, par exemple, un circuit de climatisation, une chambre froide, un refroidissement de type industriel ou scientifique (froid important voire extrême par exemple, et/ou massif c’est- à-dire pour un grand volume), etc. Ledit système de refroidissement 3 est de manière avantageuse relié fonctionnellement audit bâtiment. De préférence, ledit châssis 4 est fixe, et n’est pas destiné à être déplacé une fois installé. Avantageusement, ledit châssis 4 présente ladite forme de parallélépipède rectangle, et forme au moins la partie extérieure du groupe froid 2, ledit châssis 4 permettant à la fois de protéger le système de refroidissement 3 et l’entretien de ce dernier, certaines parties dudit châssis 4 présentant en particulier des ouvertures sur l’extérieur du groupe froid 2. Ainsi, ledit groupe froid 2 comprend préférentiellement des orifices 8, par exemple des orifices de ventilation 8. According to the invention, said cold unit 2 comprises a cooling system 3 as well as a frame 4 enclosing said cooling system 3. Said cooling system 3 comprises for example one or more thermodynamic machines, which can be designed for supply a cooled fluid to said building or to an industrial unit adjoining said building or located within the latter (the industrial unit possibly constituting the building as such), so as to provide, for example, an air conditioning circuit, a cold room, industrial or scientific type cooling (severe or even extreme cold for example, and / or massive, that is to say for a large volume), etc. Said cooling system 3 is advantageously operatively connected to said building. Preferably, said frame 4 is fixed, and is not intended to be moved once installed. Advantageously, said chassis 4 has said shape of a rectangular parallelepiped, and forms at least the outer part of the cold unit 2, said chassis 4 making it possible both to protect the cooling system 3 and the maintenance of the latter, certain parts of said chassis 4 having in in particular, openings to the outside of the cold unit 2. Thus, said cold unit 2 preferably comprises orifices 8, for example ventilation orifices 8.
Selon l’invention également, ledit châssis 4 comprend une surface supérieure externe 5 sensiblement horizontale formant une plate-forme 6 sur laquelle un opérateur 7 peut se tenir pour procéder à une intervention de maintenance dudit groupe froid 2. Ladite surface supérieure externe 5 est ainsi préférentiellement tournée vers le haut, c’est-à-dire vers le ciel lorsque le groupe froid 2 est situé à l’extérieur dudit bâtiment. De préférence, ladite surface supérieure externe 5 est sensiblement horizontale, c’est-à-dire globalement horizontale ou présentant alternativement une pente, relativement légère, par rapport à l’horizontale, par exemple de +/- 10°, ladite pente étant donc de façon avantageuse suffisamment faible pour que l'opérateur 7 puisse se tenir sur ladite plate-forme 6 sans difficulté. Ladite surface supérieure externe 5 est avantageusement au moins en partie plate, la partie plate de ladite surface supérieure externe 5 formant en particulier la plate forme 6 sur laquelle l’opérateur 7 peut se tenir, et se déplacer pour procéder à des interventions de maintenance dudit groupe froid 2. La forme de parallélépipède dudit groupe froid 2 et plus précisément dudit châssis 4 présente de préférence, d’un point de vue extérieur, quatre côtés sensiblement verticaux parallèles deux à deux, et deux faces sensiblement horizontales parallèles l’une à l’autre, l’une desdites deux faces étant posée, par exemple sur le sol ou le toit du bâtiment, et l’autre étant tournée vers le haut et comprenant ou formant ladite surface supérieure externe 5 Also according to the invention, said frame 4 comprises a substantially horizontal outer upper surface 5 forming a platform 6 on which an operator 7 can stand in order to carry out maintenance on said cold unit 2. Said outer upper surface 5 is thus preferably facing upwards, that is to say towards the sky when the cold unit 2 is located outside said building. Preferably, said outer upper surface 5 is substantially horizontal, that is to say generally horizontal or alternatively having a slope, relatively slight, with respect to the horizontal, for example of +/- 10 °, said slope therefore being advantageously low enough so that the operator 7 can stand on said platform 6 without difficulty. Said outer upper surface 5 is advantageously at least partly flat, the flat part of said outer upper surface 5 forming in particular the platform 6 on which the operator 7 can stand, and move to carry out maintenance operations on said cold unit 2. The parallelepiped shape of said cold unit 2 and more precisely of said frame 4 preferably has, from an external point of view, four substantially vertical sides parallel two by two, and two substantially horizontal faces parallel to one another. 'other, one of said two faces being placed, for example on the ground or the roof of the building, and the other being turned upwards and comprising or forming said outer upper surface
Lesdits orifices 8, et notamment lesdits orifices de ventilation 8, sont par exemple ménagés au niveau de ladite surface supérieure externe 5, et délimités chacun par une paroi latérale d’orifice 9 respective qui peut notamment être cylindrique comme illustré à la figure 1 . Ladite paroi latérale d’orifice 9 s’élève de préférence sensiblement à la verticale. L’opérateur 7 peut par exemple intervenir sur le groupe froid 2 en se hissant sur ladite plate-forme 6 pour nettoyer, avec une lance à haute pression via lesdits orifices de ventilation 8, des éléments mécaniques du système de refroidissement 3, tels que des organes de ventilation situés dans ces orifices de ventilation 8 et en partie protégés par ladite paroi latérale d’orifice 9, ceci étant un exemple illustratif et non limitatif d’une intervention de maintenance possible dudit groupe froid 2. Said openings 8, and in particular said ventilation openings 8, are for example formed at said outer upper surface 5, and each delimited by a respective side wall of orifice 9 which may in particular be cylindrical as illustrated in FIG. 1. Said side wall of orifice 9 preferably rises substantially vertically. The operator 7 can for example intervene on the cold unit 2 by hoisting himself on said platform 6 to clean, with a high pressure lance via said ventilation openings 8, the mechanical elements of the cooling system 3, such as ventilation units located in these ventilation openings 8 and partly protected by said side wall of orifice 9, this being an illustrative and non-limiting example of a possible maintenance intervention of said chiller 2.
Selon l’invention, l’ensemble de refroidissement 1 comprend en outre un garde-corps 10 s’étendant autour et/ou le long de la périphérie de ladite surface supérieure externe 5 pour empêcher ledit opérateur 7 de chuter. En particulier, ledit garde-corps 10 permet avantageusement audit opérateur 7 et/ou à son équipement d’être retenu physiquement sur la plate-forme 6 en formant une barrière entre ledit opérateur 7 et/ou à son équipement situé sur la plate-forme 6 d’une part et le vide au voisinage du groupe froid 2 d’autre part. Ledit garde-corps 10 est donc, de façon avantageuse, une rambarde permettant de délimiter ladite plate-forme 6 et de la sécuriser, afin de réaliser ledit ensemble de refroidissement 1 selon l’invention qui est donc sécurisé. Ledit garde- corps 10 forme en particulier une balustrade s’élevant des contours de ladite surface supérieure externe 5 ou à proximité de ces contours (c’est-à-dire la périphérie), par exemple à moins de 20 cm de ces contours. Ledit opérateur 7, lorsqu’il se tient et se déplace sur ladite plate-forme 6 (et donc en substance sur ledit groupe froid 2), est ainsi entouré par ledit garde-corps 10 et peut procéder en toute sécurité aux interventions de maintenance requises. La périphérie, ou le contour, de la surface supérieure externe 5, et plus précisément de la plate-forme 6, est préférentiellement de forme carrée ou rectangulaire. Ledit garde-corps 10 est préférentiellement installé de façon permanente, c’est-à-dire qu’il n’est avantageusement pas conçu pour être entièrement monté et démonté à chaque utilisation (pour sécuriser l’opérateur 7), c’est-à-dire à chaque fois que ledit opérateur 7 réalise une intervention de maintenance sur ladite plate-forme 6. Ledit garde-corps 10 est donc préférentiellement destiné à équiper de manière permanente ledit groupe froid 2. According to the invention, the cooling assembly 1 further comprises a guardrail 10 extending around and / or along the periphery of said outer upper surface 5 to prevent said operator 7 from falling. In particular, said guardrail 10 advantageously allows said operator 7 and / or his equipment to be physically retained on the platform 6 by forming a barrier between said operator 7 and / or his equipment located on the platform. 6 on the one hand and the vacuum in the vicinity of the chiller 2 on the other hand. Said guardrail 10 is therefore, advantageously, a guardrail making it possible to delimit said platform 6 and to secure it, in order to produce said cooling assembly 1 according to the invention which is therefore secure. Said guardrail 10 in particular forms a balustrade rising from the contours of said outer upper surface 5 or close to these contours (that is to say the periphery), for example at less than 20 cm from these contours. Said operator 7, when he stands and moves on said platform 6 (and therefore in substance on said cold unit 2), is thus surrounded by said guardrail 10 and can safely carry out the required maintenance interventions. . The periphery, or the contour, of the outer upper surface 5, and more precisely of the platform 6, is preferably square or rectangular in shape. Said guardrail 10 is preferably permanently installed, that is to say that it is advantageously not designed to be completely assembled and dismantled at each use (to secure the operator 7), ie. that is to say each time said operator 7 carries out a maintenance intervention on said platform 6. Said guardrail 10 is therefore preferably intended to permanently equip said cold unit 2.
De façon avantageuse, la hauteur dudit garde-corps 10 mesurée à partir de ladite surface supérieure externe 5 est comprise entre 80 et 140 cm, de préférence entre 90 et 130 cm, plus préférentiellement entre 100 et 120 cm, bornes incluses. Par hauteur de garde-corps 10 on entend de préférence la hauteur maximum de ce dernier (et notamment la hauteur de la lisse supérieure 12 qui sera décrite plus en détail ci-après). Ledit garde-corps 10 est préférentiellement au moins en partie réalisé en résine isophtalique. Ladite résine isophtalique est donc de préférence un matériau polymère, plus préférentiellement un polyester, réalisé au moins en partie, voire en totalité ou quasi-totalité, à partir d’acide isophtalique. Alternativement, ou de manière complémentaire avec ce qui précède, ledit garde-corps 10 est réalisé au moins en partie en un ou plusieurs polymères (autres que ceux mentionnés ci-avant), ou encore en un ou plusieurs métaux, tels que l’acier et Paluminium. Advantageously, the height of said guardrail 10 measured from said outer upper surface 5 is between 80 and 140 cm, preferably between 90 and 130 cm, more preferably between 100 and 120 cm, limits included. By height of guardrail 10 is preferably meant the maximum height of the latter (and in particular the height of the upper rail 12 which will be described in more detail below). Said guardrail 10 is preferably at least partly made of isophthalic resin. Said isophthalic resin is therefore preferably a polymeric material, more preferably a polyester, produced at least in part, or even in whole or almost entirely, from acid isophthalic. Alternatively, or in a complementary manner with the above, said guardrail 10 is made at least in part from one or more polymers (other than those mentioned above), or even from one or more metals, such as steel and Aluminum.
L’invention concerne également en tant que tel, selon un deuxième aspect illustré aux figures, un procédé de sécurisation d’un groupe froid 2 équipant un bâtiment. La description qui précède, comme celle qui suit, concernant l’ensemble de refroidissement sécurisé 1 s’applique avantageusement également au procédé de sécurisation selon l’invention, et inversement, la description qui suit concernant le procédé de sécurisation s’applique de préférence également à l’ensemble de refroidissement sécurisé 1 selon l’invention. Ainsi, selon le deuxième aspect de l’invention, ledit groupe froid 2 comprend un système de refroidissement 3 ainsi qu’un châssis 4 renfermant ledit système de refroidissement 3, ledit châssis 4 comprenant une surface supérieure externe 5 sensiblement horizontale formant une plate-forme 6 sur laquelle un opérateur 7 peut se tenir pour procéder à une intervention de maintenance dudit groupe froid 2. The invention also relates as such, according to a second aspect illustrated in the figures, a method of securing a cold unit 2 equipping a building. The above description, like that which follows, concerning the secure cooling assembly 1 advantageously also applies to the securing method according to the invention, and conversely, the following description relating to the securing method preferably also applies. to the secure cooling assembly 1 according to the invention. Thus, according to the second aspect of the invention, said cold unit 2 comprises a cooling system 3 as well as a frame 4 enclosing said cooling system 3, said frame 4 comprising a substantially horizontal outer upper surface 5 forming a platform. 6 on which an operator 7 can stand to carry out a maintenance intervention on said cold unit 2.
Selon l’invention, le procédé de sécurisation comprend l’installation permanente d’un garde-corps 10 (de préférence tel que mentionné ci-avant) s’étendant autour et/ou le long de la périphérie de ladite surface supérieure externe 5 pour empêcher ledit opérateur 7 de chuter. Le garde-corps 10 est avantageusement conçu pour équiper de manière permanente ledit groupe froid 2 (et plus précisément ledit châssis 4), de façon à sécuriser ce dernier de manière permanente. En effet, généralement, l’opérateur 7 intervient de manière régulière sur la plate-forme 6 pour réaliser l’entretien et la maintenance du groupe froid 2, de telles interventions de maintenance étant même souvent planifiées longtemps à l’avance. Grâce au procédé de sécurisation de l’invention, il est possible de sécuriser définitivement la plate-forme 6 du groupe froid 2 de manière simple, rapide et particulièrement efficace, en remplissant les exigences des normes de sécurité en ce qui concerne le travail en hauteur sur la plate-forme 6 de groupe froid 2. According to the invention, the securing method comprises the permanent installation of a guardrail 10 (preferably as mentioned above) extending around and / or along the periphery of said outer upper surface 5 for preventing said operator 7 from falling. The guardrail 10 is advantageously designed to permanently equip said cold unit 2 (and more precisely said frame 4), so as to secure the latter permanently. Indeed, generally, the operator 7 intervenes on a regular basis on the platform 6 to carry out the maintenance and maintenance of the cold unit 2, such maintenance interventions often even being planned well in advance. Thanks to the securing method of the invention, it is possible to definitively secure the platform 6 of the cold unit 2 in a simple, rapid and particularly efficient manner, by fulfilling the requirements of safety standards with regard to work at height. on the cold group platform 6 2.
Selon un mode de réalisation particulier, illustré aux figures, ledit garde-corps 10 comprend préférentiellement au moins : According to a particular embodiment, illustrated in the figures, said guardrail 10 preferably comprises at least:
- des montants 11 , fixés audit châssis 4 de façon à s’étendre verticalement ou à l’oblique, - une lisse supérieure 12 sensiblement horizontale reliant lesdits montants 1 1 entre eux, ladite lisse supérieure 12 formant ainsi une main courante dudit garde-corps 10. - uprights 11, fixed to said frame 4 so as to extend vertically or obliquely, - A substantially horizontal upper rail 12 connecting said uprights 1 1 to each other, said upper rail 12 thus forming a handrail of said railing 10.
Ainsi, selon un mode de réalisation particulier du deuxième aspect de l’invention, l’installation dudit garde-corps 10 comprend avantageusement au moins : Thus, according to a particular embodiment of the second aspect of the invention, the installation of said guardrail 10 advantageously comprises at least:
- une étape de fixation de montants 11 audit châssis 4, de façon à ce que ces derniers s’étendent verticalement ou à l’oblique, - a step of fixing uprights 11 to said frame 4, so that the latter extend vertically or obliquely,
- une étape d’assemblage au cours de laquelle une lisse supérieure 12 est installée de façon à être sensiblement horizontale et à relier lesdits montants 1 1 entre eux, ladite lisse supérieure 12 formant ainsi une main courante dudit garde-corps 10. - An assembly step during which an upper rail 12 is installed so as to be substantially horizontal and to connect said uprights 1 1 together, said upper rail 12 thus forming a handrail of said railing 10.
De manière préférentielle, ledit garde-corps 10 présente globalement une tenue mécanique propre, c’est-à-dire qu’il n’est pas flasque, et même avantageusement sensiblement rigide. En particulier, lesdits montants 1 1 et ladite lisse supérieure 12 présentent de préférence une tenue mécanique propre, c’est-à-dire qu’ils ne sont pas flasques, et même sont plus préférentiellement sensiblement rigides. Preferably, said guardrail 10 generally has its own mechanical strength, that is to say that it is not flaccid, and even advantageously substantially rigid. In particular, said uprights 1 1 and said upper rail 12 preferably have their own mechanical strength, that is to say that they are not flanged, and even are more preferably substantially rigid.
Lesdits montants 11 sont de manière avantageuse des profilés, par exemple à section carrée ou rectangulaire, et peuvent présenter des percements primaires pour le passage de moyens d’attache tels que des vis d’un ensemble vis/écrous (ou boulon), par exemple pour attacher lesdits montants 11 à ladite lisse supérieure 12 et/ou audit châssis 4. Ladite lisse supérieure 12 est de façon préférentielle formée par un ensemble de profilés supérieurs 15, qui peuvent présenter des percements secondaires pour le passage de moyens d’attache tels que des vis d’un ensemble vis/écrous, par exemple pour attacher ladite lisse supérieure 12 auxdits montants 1 1 , certains au moins desdits percements primaires et secondaires étant alors mis en correspondance. Said uprights 11 are advantageously profiles, for example with a square or rectangular section, and may have primary openings for the passage of fastening means such as screws of a screw / nut (or bolt) assembly, for example to attach said uprights 11 to said upper rail 12 and / or to said frame 4. Said upper rail 12 is preferably formed by a set of upper sections 15, which may have secondary openings for the passage of fastening means such as screws of a screw / nut assembly, for example for attaching said upper rail 12 to said uprights 1 1, at least some of said primary and secondary openings then being put in correspondence.
Par exemple, comme illustré à la figure 2 notamment, ladite lisse supérieure 12 (et plus précisément chaque profilé supérieur 15) présente un profil en forme de U inversé, lesdits montants 1 1 présentant alors chacun une extrémité respective 13 s’emboîtant dans le creux 14 dudit profil en forme de U inversé, comme illustré aux figures 1 , 12 et 14. Une telle configuration en U inversé permet d’assurer une meilleure ergonomie de la main courante formée par la lisse supérieure 12, celle-ci permettant une meilleure préhension par ledit opérateur 7. Ledit procédé de sécurisation comprend selon cet exemple une étape d’emboîtement d’une extrémité respective 13 de chacun desdits montants 1 1 dans le creux 14 dudit profil en forme de U inversé. For example, as illustrated in Figure 2 in particular, said upper rail 12 (and more precisely each upper section 15) has an inverted U-shaped profile, said uprights 1 1 then each having a respective end 13 fitting into the hollow 14 of said inverted U-shaped profile, as illustrated in Figures 1, 12 and 14. Such an inverted U-shaped configuration ensures better ergonomics of the handrail formed by the upper rail 12, the latter allowing a better grip by said operator 7. Said securing method comprises according to this example a step of interlocking a respective end 13 of each of said uprights 1 1 in the hollow 14 of said inverted U-shaped profile.
Ladite lisse supérieure 12 peut également comprendre, comme illustré aux figures 1 , 3 et 4 notamment, des parties de raccord 16. Selon un premier exemple, lesdites parties de raccord 16 sont chacune en forme de coude ou de L, chaque portion du coude ou du L étant éventuellement pourvu de ladite forme en U inversé. Ladite partie de raccord 16 est de préférence destinée à être positionnée au niveau des coins de ladite lisse supérieure 12 ou former ces derniers, au-dessus des coins dudit châssis 4, et plus précisément au-dessus des coins de ladite surface supérieure externe 5 qui sont avantageusement sensiblement à angle droit. Chaque partie de raccord 16 est avantageusement conçue pour relier au moins deux desdits profilés supérieurs 15 de ladite lisse supérieure 12, lesdits deux profilés supérieurs 15 étant de préférence droits. Selon un autre exemple, compatible avec le précédent et illustré à la figure 4 notamment, chaque partie de raccord 16 est orientable et comprend deux parties montées à pivotement 17, 18 l’une de l’autre, chaque partie montée à pivotement 17, 18 étant conçue pour être reliée à l’un desdits profilés supérieurs 15. Cette dernière configuration est particulièrement pratique lorsque le groupe froid 2 présente une forme plus rarement utilisée, la surface supérieure externe 5 étant par exemple triangulaire ou octogonale, la lisse supérieure 12 devant suivre cette forme pour former ladite main courante, ou encore lorsqu’on désire simplement faciliter l’installer de ladite lisse supérieure 12, qui est plus facile à ajuster puisque partie de la raccord 16 forme alors un coude qui peut être modifié (par pivotement desdites deux parties montées à pivotement 17, 18). Said upper rail 12 may also comprise, as illustrated in FIGS. 1, 3 and 4 in particular, connection parts 16. According to a first example, said connection parts 16 are each in the shape of an elbow or of an L, each portion of the elbow or the L being optionally provided with said inverted U shape. Said connecting portion 16 is preferably intended to be positioned at the level of the corners of said upper rail 12 or to form the latter, above the corners of said frame 4, and more precisely above the corners of said outer upper surface 5 which are advantageously substantially at right angles. Each connection part 16 is advantageously designed to connect at least two of said upper sections 15 of said upper rail 12, said two upper sections 15 preferably being straight. According to another example, compatible with the previous one and illustrated in FIG. 4 in particular, each connection part 16 is orientable and comprises two parts mounted to pivot 17, 18 from one another, each part mounted to pivot 17, 18 being designed to be connected to one of said upper sections 15. This latter configuration is particularly practical when the cold unit 2 has a shape more rarely used, the upper external surface 5 being for example triangular or octagonal, the upper rail 12 having to follow this shape to form said handrail, or when it is simply desired to facilitate the installation of said upper rail 12, which is easier to adjust since part of the fitting 16 then forms an elbow which can be modified (by pivoting said two pivotally mounted parts 17, 18).
De préférence, ledit châssis 4 comprend des longerons 19 sensiblement verticaux situés en-dessous de la périphérie de ladite surface supérieure externe 5. Plus préférentiellement encore, lesdits montants 1 1 sont plaqués contre lesdites longerons 19, comme cela est notamment illustré aux figures 1 et 15 à 18. Lesdits longerons 19 font avantageusement partie des côtés verticaux de la forme de parallélépipède rectangle dudit châssis 4. Lesdits longerons 19 se présentent par exemple chacun sous la forme d’une paroi sensiblement verticale s’étendant le long de tout ou quasiment tout un côté respectif dudit groupe froid 2. Chaque montant 1 1 plaqué contre l’un desdits longerons 19 présente avantageusement une face sensiblement plane, qui est destinée à s’étendre sensiblement verticalement et qui est plaquée contre ledit longeron 19, directement (c’est-à-dire en contact) ou indirectement (c’est-à-dire par l’intermédiaire d’une pièce de raccord entre le longeron 19 et ladite face plane). Ainsi, de manière avantageuse, au cours de ladite étape de fixation des montants 1 1 , lesdits montants 1 1 sont plaqués contre lesdites longerons 19, puis attachés à ces derniers à l’aide de moyens d’attache tels que des vis d’un ensemble vis/écrous, par exemple via lesdits percements primaires. De préférence, lesdits longerons 19 sont pourvus de percements tertiaires 20 permettant de les relier auxdits montants 1 1 , ces derniers étant pourvus de percements quaternaires 21 , certains au moins desdits percements tertiaires 20 et quaternaires 21 étant donc mis en correspondance pour effectuer cette liaison, par exemple à l’aide de moyens d’attache tels que des vis d’un ensemble vis/écrous, comme illustré de manière détaillé à la figure 14 notamment. Ainsi, ladite étape de fixation des montants 1 1 comprend avantageusement une étape de percement desdits longerons 19, afin que ces derniers soient pourvus de percements tertiaires 20 permettant de relier lesdits longerons 19 auxdits montants 11 , par exemple à l’aide de moyens d’attache tels que des vis d’un ensemble vis/écrous. La figure 14 illustre de manière détaillée le plaquage d’un des montants 11 contre un des longerons 19 de façon à mettre en correspondance lesdits percements tertiaires 20 et quaternaires 21 pour le passage via ces percements de vis d’un ensemble vis/écrous. Preferably, said frame 4 comprises substantially vertical side members 19 located below the periphery of said outer upper surface 5. More preferably still, said uprights 11 are pressed against said side members 19, as is particularly illustrated in Figures 1 and 15 to 18. Said side members 19 advantageously form part of the vertical sides of the shape of a rectangular parallelepiped of said frame 4. Said side members 19 are for example each in the form of a substantially vertical wall extending along all or almost all a respective side of said cold unit 2. Each upright 11 pressed against one of said side members 19 advantageously has a substantially planar face, which is intended to extend substantially vertically and which is pressed against said side member 19, directly (that is to say in contact) or indirectly (that is to say by means of a connecting piece between the spar 19 and said flat face). Thus, advantageously, during said step of fixing the uprights 1 1, said uprights 1 1 are pressed against said side members 19, then attached to the latter using fastening means such as screws of a screw / nut assembly, for example via said primary holes. Preferably, said side members 19 are provided with tertiary openings 20 allowing them to be connected to said uprights 1 1, the latter being provided with quaternary openings 21, at least some of said tertiary 20 and quaternary openings 21 being therefore placed in correspondence to effect this connection, for example using fastening means such as screws of a screw / nut assembly, as illustrated in detail in FIG. 14 in particular. Thus, said step of fixing the uprights 1 1 advantageously comprises a step of piercing said spars 19, so that the latter are provided with tertiary openings 20 allowing said spars 19 to be connected to said uprights 11, for example using means of fasteners such as screws from a screw / nut assembly. FIG. 14 illustrates in detail the plating of one of the uprights 11 against one of the side members 19 so as to put said tertiary 20 and quaternary 21 openings in correspondence for the passage through these screw holes of a screw / nut assembly.
De préférence, lesdits montants 1 1 sont des profilés, par exemple à section transversale carrée ou rectangulaire, sensiblement creux, lesdits montants 1 1 présentant donc chacun un espace interne 22 respectif. Ledit ensemble de refroidissement 1 comprend avantageusement des platines de renfort 23, chaque platine de renfort 23 étant conçue pour être insérée dans ledit espace interne 22 de façon à se retrouver au niveau du longeron 19 auquel le montant 1 1 est attaché, comme illustré aux figures 12 à 14. Préférentiellement, chaque platine de renfort 23 est conçue pour améliorer la résistance mécanique dudit montant 1 1 au niveau dudit longeron 19, ladite platine de renfort 23 étant en particulier pourvue d’au moins un orifice traversant 24 permettant de laisser passer un moyen d’attache, tel qu’une vis d’un ensemble vis/écrous, pour solidariser ladite platine de renfort 23 insérée dans ledit espace interne 22 à la fois audit montant 1 1 et audit longeron 19 via l’un desdits percements quaternaires 21 et l’un desdits percements tertiaires 20, respectivement. De façon avantageuse, ledit garde-corps 10 comprend au moins une lisse intermédiaire 25 reliant lesdits montants 1 1 entre eux, ladite lisse intermédiaire 25 étant située en- dessous de ladite lisse supérieure 12. En d’autres termes, de manière avantageuse, ladite lisse supérieure 12 joue le rôle de main courante du garde-corps 10, tandis que ladite lisse intermédiaire 25 s’étend à une altitude inférieure à celle de la lisse supérieure 12 mais supérieure à celle de ladite plate-forme 6, de façon à renforcer la protection conférée par le garde-corps 10 audit opérateur 7 et/ou à l’équipement de ce dernier (tournevis, lance de nettoyage haute pression, etc.). Bien évidemment, ladite lisse intermédiaire 25, comme ladite lisse supérieure 12, s’étend préférentiellement autour et/ou le long de la périphérie de ladite surface supérieure externe 5 pour empêcher ledit opérateur 7 de chuter. Comme illustré aux figures, ladite lisse intermédiaire 25 est préférentiellement formée par une pluralité de profilés, lesquels présentent par exemple une section transversale sensiblement ronde et/ou annulaire, mais qui peut aussi éventuellement être carrée, elliptique, ou toute forme appropriée. Le procédé de sécurisation comprend donc avantageusement au moins une étape de montage au cours de laquelle au moins une lisse intermédiaire 25 est installée de façon à relier lesdits montants 11 entre eux et de sorte à être située en-dessous de ladite lisse supérieure 12. Ladite lisse intermédiaire 25 est de préférence sensiblement horizontale. Preferably, said uprights 1 1 are profiles, for example with a square or rectangular cross section, substantially hollow, said uprights 1 1 therefore each having a respective internal space 22. Said cooling assembly 1 advantageously comprises reinforcing plates 23, each reinforcing plate 23 being designed to be inserted into said internal space 22 so as to be at the level of the spar 19 to which the upright 1 1 is attached, as illustrated in figures 12 to 14. Preferably, each reinforcing plate 23 is designed to improve the mechanical strength of said upright 1 1 at the level of said spar 19, said reinforcing plate 23 being in particular provided with at least one through orifice 24 allowing a through hole to pass through. fastening means, such as a screw of a screw / nut assembly, for securing said reinforcing plate 23 inserted into said internal space 22 both to said upright 1 1 and to said spar 19 via one of said quaternary openings 21 and one of said tertiary openings 20, respectively. Advantageously, said railing 10 comprises at least one intermediate rail 25 connecting said uprights 11 together, said intermediate rail 25 being located below said upper rail 12. In other words, advantageously, said upper rail 12 acts as a handrail for guardrail 10, while said intermediate rail 25 extends at an altitude lower than that of upper rail 12 but higher than that of said platform 6, so as to reinforce the protection conferred by the guardrail 10 on said operator 7 and / or on the latter's equipment (screwdriver, high pressure cleaning lance, etc.). Obviously, said intermediate rail 25, like said upper rail 12, preferably extends around and / or along the periphery of said outer upper surface 5 to prevent said operator 7 from falling. As illustrated in the figures, said intermediate rail 25 is preferably formed by a plurality of profiles, which for example have a substantially round and / or annular cross section, but which may also optionally be square, elliptical, or any suitable shape. The securing method therefore advantageously comprises at least one mounting step during which at least one intermediate rail 25 is installed so as to connect said uprights 11 to each other and so as to be located below said upper rail 12. Said rail 12. intermediate rail 25 is preferably substantially horizontal.
Ladite lisse intermédiaire 25 peut également comprendre un ou plusieurs des éléments suivants : Said intermediate rail 25 may also comprise one or more of the following elements:
- des éléments de raccord droits 27, par exemple en forme de long cylindres (et formant avantageusement des profilés), comme illustré à la figure 6, - straight connecting elements 27, for example in the form of long cylinders (and advantageously forming profiles), as illustrated in Figure 6,
- des éléments de raccord creux 26, par exemple en forme de long cylindres creux (et formant avantageusement des profilés), dans lesquels peuvent s’insérer notamment les éléments de raccord droits 27, comme illustré à la figure 5, et/ou - Hollow connection elements 26, for example in the form of long hollow cylinders (and advantageously forming profiles), into which can be inserted in particular the straight connection elements 27, as illustrated in Figure 5, and / or
- des raccords de lisse 28 conçus pour former chacun un coude de la lisse intermédiaire 25, chaque raccord de lisse 28 présentant, selon un mode de réalisation, deux parties reliées pivotantes l’une par rapport à l’autre, comme représenté à la figure 7, ou étant, selon un autre mode de réalisation, formé d’une seule pièce, comme à la figure 8. Chaque raccord de lisse 28 présente avantageusement des extrémités d’insertion 29, lesquelles présentent de préférence chacune un diamètre sensiblement égal à celui des éléments de raccord droits 27, lesdits extrémités d’insertion 29 étant en particulier destinées à s’insérer dans lesdits éléments de raccord creux 26 pour former ladite lisse intermédiaire 25. - arm connectors 28 each designed to form an elbow of the intermediate rail 25, each arm connection 28 having, according to one embodiment, two connected parts pivoting with respect to one another, as shown in FIG. 7, or being, according to another embodiment, formed in one piece, as in FIG. 8. Each arm connector 28 advantageously has insertion ends 29, which preferably each have a diameter substantially equal to that straight connecting elements 27, said insertion ends 29 being in particular intended to be inserted into said hollow connecting elements 26 to form said intermediate rail 25.
Cette configuration confère à la lisse intermédiaire 25 une grande flexibilité d’usage, et elle permet une industrialisation particulièrement facile et rapide de cette partie du garde- corps 10. This configuration gives the intermediate rail 25 great flexibility of use, and it allows particularly easy and rapid industrialization of this part of the guardrail 10.
Chaque montant 1 1 présente avantageusement au moins un orifice intermédiaire 30 conçu pour recevoir ladite lisse intermédiaire 25 de façon à être solidarisé à cette dernière. Par exemple, ledit orifice intermédiaire 30 est conçu pour recevoir l’un desdits éléments de raccord droit 27 ou creux 26. Each upright 1 1 advantageously has at least one intermediate orifice 30 designed to receive said intermediate rail 25 so as to be secured to the latter. For example, said intermediate orifice 30 is designed to receive one of said straight 27 or hollow 26 connecting elements.
Ledit orifice intermédiaire 30 peut être traversant. Ledit montant 11 pourvu d’un tel orifice intermédiaire 30 traversant est par exemple destiné à être traversé de part en part par une portion continue de ladite lisse intermédiaire 25, une telle configuration conférant audit garde-corps 10 une excellente solidité et en particulier une bonne solidarisation entre ledit montant et ladite lisse intermédiaire 25. Ladite portion de lisse intermédiaire 25 est alors préférentiellement bloquée en translation horizontale, par exemple en solidarisant ensemble deux extrémités de lisse intermédiaire 25 en regard l’une de l’autre. Said intermediate orifice 30 may be through. Said upright 11 provided with such an intermediate through orifice 30 is for example intended to be traversed right through by a continuous portion of said intermediate rail 25, such a configuration giving said guardrail 10 excellent strength and in particular good securing between said upright and said intermediate rail 25. Said portion of intermediate rail 25 is then preferably blocked in horizontal translation, for example by securing together two ends of intermediate rail 25 facing one another.
De manière avantageuse, lesdits montants 1 1 et/ou lesdites lisses principale 12 et/ou intermédiaire 25 (et/ou encore la plinthe 41 décrite ci-après) sont principalement réalisé(e)s en résine isophtalique. Cette configuration permet audit garde-corps 10 de présenter une grande résistance aux conditions extérieures (vent, humidité, pluie, neige, soleil...) et une durabilité importante, tout en ne nécessitant qu’un entretien minimal. Advantageously, said uprights 1 1 and / or said main string 12 and / or intermediate 25 (and / or the plinth 41 described below) are mainly made (s) of isophthalic resin. This configuration allows said railing 10 to have great resistance to external conditions (wind, humidity, rain, snow, sun, etc.) and high durability, while requiring only minimal maintenance.
De préférence, ladite lisse intermédiaire 25 comprend au moins une partie amovible 31 qui, lorsqu’elle est retirée, ménage un espace d’accès 32 sous ladite lisse supérieure 12 permettant à l’opérateur 7 d’accéder par l’extérieur à ladite plate-forme 6. L’aménagement de cet espace d’accès 32 est notamment illustré à la figure 29. Preferably, said intermediate rail 25 comprises at least one removable part 31 which, when it is removed, provides an access space 32 under said upper rail 12 allowing the operator 7 to access said plate from the outside. -form 6. The layout of this access space 32 is illustrated in particular in Figure 29.
Ladite partie amovible 31 est donc préférentiellement conçue pour être attachée de manière réversible au reste dudit garde-corps 10. Ainsi, ledit garde-corps 10 est avantageusement conçu de façon que la partie amovible 31 puisse passer : - d’une position montée, dans laquelle ladite partie amovible est 31 reliée au reste du garde-corps 31 , de sorte que ladite lisse intermédiaire 25 soit complète, sans ledit espace d’accès 32 et donc en d’autres termes sans interruption particulière, fournissant ainsi une protection optimale contre la chute de l’opérateur, comme illustré aux figures 1 , 25 et 28 notamment, Said removable part 31 is therefore preferably designed to be reversibly attached to the rest of said railing 10. Thus, said railing 10 is advantageously designed so that the removable part 31 can pass: - a mounted position, in which said removable part 31 is connected to the rest of the guardrail 31, so that said intermediate rail 25 is complete, without said access space 32 and therefore in other words without particular interruption , thus providing optimum protection against the fall of the operator, as illustrated in Figures 1, 25 and 28 in particular,
- à une position démontée, dans laquelle ladite partie amovible 31 a été détachée du reste du garde-corps 10 et par exemple entreposée sur la plate-forme 6, ladite lisse intermédiaire 25 étant donc incomplète et présentant une interruption, c’est-à-dire ledit espace d’accès 32, situé sous ladite lisse supérieure 12 et au-dessus de la périphérie de la plate-forme 6, ledit espace d’accès 32 constituant ainsi un passage pour que l’opérateur 7 puisse accéder plus facilement à la plate-forme 6, comme illustré à la figure 29 notamment, - in a disassembled position, in which said removable part 31 has been detached from the rest of the guardrail 10 and for example stored on the platform 6, said intermediate rail 25 therefore being incomplete and having an interruption, that is to say say said access space 32, located under said upper rail 12 and above the periphery of the platform 6, said access space 32 thus constituting a passage so that the operator 7 can access it more easily the platform 6, as illustrated in FIG. 29 in particular,
- et inversement, pour que ladite partie amovible 31 puisse passer de ladite position démontée à ladite position montée. - And vice versa, so that said removable part 31 can pass from said dismantled position to said mounted position.
Ladite partie amovible 31 peut préférentiellement être détachée du reste du garde- corps 10 sans qu’il soit nécessaire de démonter d’autres éléments structurels de dernier, et en particulier l’un ou plusieurs desdits montants 1 1 , la lisse supérieure 12, ou encore le reste de la lisse intermédiaire 25 (c’est-à-dire la partie fixe 33 décrite ci-après). Said removable part 31 can preferably be detached from the rest of the railing 10 without it being necessary to dismantle other structural elements of the last, and in particular one or more of said uprights 1 1, the upper rail 12, or again the rest of the intermediate rail 25 (that is to say the fixed part 33 described below).
Ledit garde-corps 10, bien qu’aisé à installer et relativement facile à démonter, n’est préférentiellement pas une structure temporaire, et est avantageusement destiné à rester attaché au châssis 4 dudit groupe froid 2. Said guardrail 10, although easy to install and relatively easy to dismantle, is preferably not a temporary structure, and is advantageously intended to remain attached to the frame 4 of said cold unit 2.
De façon préférentielle, le procédé de sécurisation comprend ainsi une étape de mise en place d’au moins une partie amovible 31 de ladite lisse intermédiaire 25, de façon que lorsque ladite partie amovible 31 est retirée (c’est-à-dire démontée, ou en position démontée décrite ci-avant), elle ménage un espace d’accès 32 sous ladite lisse supérieure 12 permettant à l’opérateur 7 d’accéder par l’extérieur à ladite plate-forme 6. Preferably, the securing method thus comprises a step of fitting at least one removable part 31 of said intermediate rail 25, so that when said removable part 31 is removed (that is to say dismantled, or in the disassembled position described above), it provides an access space 32 under said upper rail 12 allowing the operator 7 to access said platform 6 from the outside.
De préférence, ledit espace d’accès 32 permet également à l’opérateur 7 de quitter ladite plate-forme 6. Par exemple, le garde-corps 10 est conçu pour que l’opérateur 7 puisse démonter facilement ladite partie amovible 31 lorsqu’il souhaite accéder à la plateforme 6. Une fois qu’il se tient sur cette dernière, l’opérateur 7 remonte ladite partie amovible 31 (avec le reste dudit garde-corps 10), de façon que la lisse intermédiaire 25 soit complète et la protection fournie par le garde-corps 10 optimale. Lorsque l’opérateur désire quitter ladite plate-forme 6, il démonte à nouveau ladite partie amovible 31 , depuis l’intérieur de la plate-forme 6 cette fois, puis la remonte depuis l’extérieur. Ainsi, le garde- corps 10 est conçu de façon que, lorsque lesdites parties amovible 31 et fixe 33 sont toutes les deux montées, ou plus simplement lorsque ladite partie amovible 31 est montée au reste dudit garde-corps 10, ladite lisse intermédiaire 25 est complète, c’est-à- dire entièrement montée pour sécuriser l'ensemble de refroidissement 1 lorsque l’opérateur 7 se tient sur la plate-forme 6. Preferably, said access space 32 also allows the operator 7 to leave said platform 6. For example, the guardrail 10 is designed so that the operator 7 can easily remove said removable part 31 when wishes to access the platform 6. Once he is standing on the latter, the operator 7 goes up said part removable 31 (with the rest of said railing 10), so that the intermediate rail 25 is complete and the protection provided by the railing 10 is optimal. When the operator wishes to leave said platform 6, he dismantles said removable part 31 again, from the inside of platform 6 this time, then reassembles it from the outside. Thus, the guardrail 10 is designed so that, when said removable 31 and fixed 33 parts are both mounted, or more simply when said removable part 31 is mounted to the rest of said guardrail 10, said intermediate rail 25 is complete, i.e. fully assembled to secure the cooling assembly 1 when the operator 7 is standing on the platform 6.
De façon avantageuse, ladite lisse intermédiaire 25 comprend au moins une partie fixe 33 conçue pour coopérer avec ladite partie amovible 31. Selon un mode de réalisation particulier, dont un exemple est illustré aux figures 19 à 22 notamment, ladite coopération (entre lesdites parties fixe 33 et amovible 31) est réalisée par emboîtement desdites parties fixe 33 et amovible 31 l’une dans l’autre. Advantageously, said intermediate rail 25 comprises at least one fixed part 33 designed to cooperate with said removable part 31. According to a particular embodiment, an example of which is illustrated in Figures 19 to 22 in particular, said cooperation (between said fixed parts 33 and removable 31) is produced by fitting said fixed 33 and removable 31 parts into one another.
Par exemple, ladite partie amovible 31 présente une forme générale de tuyau (creux) coudé ou de cylindre (plein) qui a été courbé de façon à former un coude, et comprend une première extrémité 34 qui, de préférence, est sensiblement effilée, et/ou présente un diamètre et/ou une section transversale inférieur(e) à celui/celle du reste de la partie amovible 31. Ladite première extrémité 34 est ainsi avantageusement conçue pour s’emboîter dans ladite partie fixe 33, par exemple dans l’un desdits éléments de raccord creux 26 faisant partie de ladite partie fixe 33. Une telle configuration est notamment illustrée aux figures 19 à 22, qui représentent la mise en correspondance et l’insertion progressive de ladite première extrémité 34 avec le creux d’un raccord creux 26. De manière avantageuse, ladite étape de mise en place comprend ainsi une étape de coopération entre une partie fixe 33 de ladite lisse intermédiaire 25 et ladite partie amovible 31. Ladite étape de coopération comprend avantageusement une étape d’emboîtement desdites parties fixe 33 et amovible 31 l’une dans l’autre, au cours de laquelle, de façon préférentielle, ladite première extrémité 34 s’emboîte dans ladite partie fixe 33 (et plus précisément dans un creux de ladite partie fixe 33). For example, said removable portion 31 has the general shape of an elbow (hollow) pipe or of a (solid) cylinder which has been bent so as to form an elbow, and comprises a first end 34 which is preferably substantially tapered, and / or has a diameter and / or a cross section smaller than that of the rest of the removable part 31. Said first end 34 is thus advantageously designed to fit into said fixed part 33, for example in the one of said hollow connection elements 26 forming part of said fixed part 33. Such a configuration is particularly illustrated in Figures 19 to 22, which represent the matching and progressive insertion of said first end 34 with the hollow of a fitting hollow 26. Advantageously, said step of placing thus comprises a step of cooperation between a fixed part 33 of said intermediate rail 25 and said removable part 31. Said step of cooperation comprises before conveniently a step of fitting said fixed 33 and removable 31 parts into one another, during which, preferably, said first end 34 fits into said fixed part 33 (and more precisely in a hollow of said fixed part 33).
Préférentiellement, l’ensemble de refroidissement sécurisé 1 comprend une goupille de verrouillage 35 et lesdites parties fixe 33 et amovible 31 sont conçues pour être verrouillées l’une à l’autre de manière réversible à l’aide de ladite goupille 35, lorsque cette dernière traverse lesdites parties fixe 33 et amovible 31 , ces dernières (parties fixe 33 et amovible 31) étant alors avantageusement mises en correspondance, une telle mise en correspondance étant illustrée aux figures 19 à 22, en quatre étapes ou positions successives. Par exemple, lesdites parties fixe 33 et amovible 31 comprennent respectivement un premier et un second orifice de verrouillage 36, 37, lesdits premier et second orifices de verrouillage 36, 37 étant conçus pour recevoir ladite goupille 35 de façon que celle-ci traverse à la fois ladite partie fixe 33 et ladite partie amovible 31 pour les bloquer ensemble, ou en d’autres termes pour empêcher qu’elles se désolidarisent une fois emboîtées l’une dans l’autre. Ladite goupille de verrouillage 35 est par exemple une goupille bêta, comme illustré aux figures 22 et 25. Preferably, the secure cooling assembly 1 comprises a locking pin 35 and said fixed 33 and removable 31 parts are designed to be locked to one another in a reversible manner using said pin 35, when the latter passes through said fixed 33 and removable 31 parts, the latter (fixed 33 and removable 31 parts) then being advantageously matched, a such a correspondence being illustrated in FIGS. 19 to 22, in four successive steps or positions. For example, said fixed 33 and removable 31 parts respectively comprise a first and a second locking hole 36, 37, said first and second locking hole 36, 37 being designed to receive said pin 35 so that the latter passes through both said fixed part 33 and said removable part 31 to block them together, or in other words to prevent them from coming apart once they are nested in one another. Said locking pin 35 is for example a beta pin, as illustrated in Figures 22 and 25.
Lesdites parties fixe 33 et amovible 31 sont préférentiellement conçues pour être traversées par ladite goupille de verrouillage 35 au niveau dudit emboîtement. En d’autres termes, la lisse intermédiaire 25 est conçue pour que la goupille de verrouillage 35 verrouille lesdites parties fixe 33 et amovible 31 ensemble au niveau d’une portion emboîtée de l’une desdites parties fixe 33 et amovible 31 dans l’autre desdites parties fixe 33 et amovible 31. Ladite étape de coopération comprend donc préférentiellement une étape de verrouillage réversible desdites parties fixe 33 et amovible 31 à l’aide d’une goupille de verrouillage 35, lorsque cette dernière traverse lesdites parties fixe 33 et amovible 31. La figure 19 présente ainsi une situation où lesdites parties fixe 33 et amovible 31 ne sont pas reliées ensemble, mais sont rapprochées, tandis que la figure 20 présente une situation où ladite première extrémité 34 de ladite partie amovible 31 est partiellement emboîtée dans ladite partie fixe 33 (plus précisément un des raccords creux 26 de cette dernière) et la figure 21 présente une configuration où ladite première extrémité 34 de ladite partie amovible 31 est totalement emboîtée dans ladite partie fixe 33, lesdits premier et un second orifices de verrouillage 36, 37 étant alors mis en correspondance l’un avec l’autre, la figure 22 présentant une configuration finale de verrouillage dans laquelle ladite goupille de verrouillage 35 a été insérée dans lesdits premier et second orifices de verrouillage 36, 37, solidarisant ainsi lesdites parties fixe 33 et amovible 31. Les configurations présentées aux figures 19 à 22 sont ainsi avantageusement réalisées successivement dans cet ordre pour le montage de ladite partie amovible 31 , et les configurations présentées aux figures 22 à 19 sont ainsi préférentiellement réalisées successivement dans cet ordre (inverse au montage donc) pour le démontage de ladite partie amovible 31. De préférence, ladite première extrémité 34 présente un diamètre sensiblement égal à celui desdits raccords droits 27, et/ou forme une partie d’un desdits raccords droits 27. Said fixed 33 and removable 31 parts are preferably designed to be traversed by said locking pin 35 at the level of said fitting. In other words, the intermediate rail 25 is designed so that the locking pin 35 locks said fixed 33 and removable 31 parts together at the level of a nested portion of one of said fixed 33 and removable 31 parts in the other. said fixed 33 and removable 31 parts. Said cooperation step therefore preferably comprises a reversible locking step of said fixed 33 and removable 31 parts using a locking pin 35, when the latter passes through said fixed 33 and removable 31 parts. Figure 19 thus presents a situation where said fixed 33 and removable 31 parts are not connected together, but are brought together, while Figure 20 presents a situation where said first end 34 of said removable portion 31 is partially fitted into said part. fixed 33 (more precisely one of the hollow fittings 26 of the latter) and Figure 21 shows a configuration where said first end 34 of said part The removable 31 is completely fitted into said fixed part 33, said first and second locking holes 36, 37 then being brought into correspondence with each other, FIG. 22 showing a final locking configuration in which said locking pin locking 35 has been inserted into said first and second locking holes 36, 37, thus securing said fixed 33 and removable 31 parts. The configurations shown in Figures 19 to 22 are thus advantageously carried out successively in this order for mounting said removable part 31, and the configurations presented in FIGS. 22 to 19 are thus preferably carried out successively in this order (therefore reverse to assembly) for disassembling said removable part 31. Preferably, said first end 34 has a diameter substantially equal to that of said straight connectors 27, and / or forms part of one of said straight connectors 27.
De préférence, au moins l’un desdits montants 1 1 est conçue pour coopérer avec ladite partie amovible 31. Selon un mode de réalisation particulier, dont un exemple est illustré à la figure 24, ladite coopération (entre ladite partie amovible 31 et ledit montant 1 1 ) est réalisée par emboîtement d’un desdits montants 1 1 et de la partie amovible 31 l’un dans l’autre. Par exemple, ladite partie amovible 31 présente la même forme que ce qui a été précédemment décrit, et comprend une seconde extrémité 38, de préférence sensiblement à l’opposé de la première extrémité 34, ladite seconde extrémité 38 étant avantageusement conçue pour s’emboîter dans ledit montant 11 , par exemple dans ledit orifice intermédiaire 30 de ce montant 1 1. La portion de ladite partie amovible 31 comprenant ladite seconde extrémité 38 est par exemple formée par l’un desdits raccords creux 26, dont le diamètre est avantageusement particulièrement adapté pour l’insertion ajustée de ladite seconde extrémité 38 dans ledit orifice intermédiaire 30 de façon qu’elle se coince dans ce dernier. Preferably, at least one of said uprights 1 1 is designed to cooperate with said removable part 31. According to a particular embodiment, an example of which is illustrated in Figure 24, said cooperation (between said removable part 31 and said upright January 1) is produced by fitting one of said uprights 1 1 and the removable part 31 into one another. For example, said removable part 31 has the same shape as what has been previously described, and comprises a second end 38, preferably substantially opposite to the first end 34, said second end 38 being advantageously designed to fit together in said upright 11, for example in said intermediate orifice 30 of this upright 1 1. The portion of said removable part 31 comprising said second end 38 is for example formed by one of said hollow fittings 26, the diameter of which is advantageously particularly suitable for the snug insertion of said second end 38 into said intermediate orifice 30 so that it wedges in the latter.
Ainsi, ladite partie amovible 31 est avantageusement reliée par un bout (ladite première extrémité 34) au reste de ladite lisse intermédiaire 25 (et plus précisément ladite partie fixe 33), et par un autre bout (ladite seconde extrémité 38) à l’un desdits montants 11 de préférence via l’orifice intermédiaire 30 de ce dernier. De manière avantageuse, lors de ladite étape de mise en place, ladite partie amovible 31 coopère avec l’un desdits montants 11 , de préférence par emboîtement desdits montant 11 et partie amovible 31 , ladite seconde extrémité 38 s’emboîtant avantageusement dans ledit montant 1 1 , et plus précisément dans ledit orifice intermédiaire 30 de ce dernier. Thus, said removable part 31 is advantageously connected by one end (said first end 34) to the rest of said intermediate rail 25 (and more precisely said fixed part 33), and by another end (said second end 38) to one of said uprights 11 preferably via the intermediate orifice 30 of the latter. Advantageously, during said fitting step, said removable part 31 cooperates with one of said uprights 11, preferably by interlocking said upright 11 and removable part 31, said second end 38 advantageously fitting into said upright 1 1, and more precisely in said intermediate orifice 30 of the latter.
De façon avantageuse, ladite partie amovible 31 présente un signe visuel distinctif 39 permettant à l’opérateur 7 de la différencier visuellement de ladite partie fixe 33. Ledit signe distinctif visuel 39 peut être notamment une marque (nervures, etc.), une couleur (peinture par exemple), une lumière, une forme, etc., et permet avantageusement de distinguer visuellement ladite partie amovible 31 de ladite partie fixe 33, cette dernière étant donc préférentiellement dépourvue de ce signe visuel distinctif 39. Bien évidemment, il est tout à fait possible que le signe visuel distinctif 39 soit constitué par une absence de marquage particulier lorsque ladite partie fixe 33 présente un marquage distinctif et pas ladite partie amovible 31 , cette dernière se distinguant de toute façon sans ambiguïté de ladite partie fixe 33, l’absence de marquage distinctif formant en tant que tel ledit signe visuel distinctif 39. De préférence, ladite partie amovible 31 forme une portion de la lisse intermédiaire 25 plus petite que celle formée par ladite partie fixe 33. Advantageously, said removable part 31 has a distinctive visual sign 39 allowing the operator 7 to visually differentiate it from said fixed part 33. Said visual distinctive sign 39 may in particular be a mark (ribs, etc.), a color ( paint for example), a light, a shape, etc., and advantageously makes it possible to visually distinguish said removable part 31 from said fixed part 33, the latter therefore preferably being devoid of this distinctive visual sign 39. Obviously, it is entirely possible that the distinctive visual sign 39 is constituted by an absence of particular marking when said fixed part 33 has a distinctive marking and not said removable part 31, the latter being distinguished in any case unambiguously from said fixed part 33, the absence of distinctive marking forming as such said visual sign distinctive 39. Preferably, said removable part 31 forms a portion of the intermediate rail 25 smaller than that formed by said fixed part 33.
Ainsi, selon un mode de réalisation particulier, le procédé de sécurisation comprend et/ou permet de réaliser, de manière avantageuse, l’une ou plusieurs des étapes suivantes, partiellement illustrées aux figures 19 à 22, 24, 25, 28 et 29 : Thus, according to a particular embodiment, the securing method comprises and / or makes it possible to carry out, advantageously, one or more of the following steps, partially illustrated in Figures 19 to 22, 24, 25, 28 and 29:
- une étape de détection visuelle de ladite partie amovible 31 , au cours de laquelle l’opérateur 7 détecte cette dernière en repérant ledit signe visuel distinctif 39, - a step of visually detecting said removable part 31, during which the operator 7 detects the latter by locating said distinctive visual sign 39,
- une étape de placement d’une échelle 40 contre ledit groupe froid 2, comme illustré à la figure 28 notamment, pour que l’opérateur 7 puisse grimper sur ladite échelle de façon à se rapprocher de ladite plate-forme 6 et atteindre ladite partie amovible 31 , ladite échelle 40 étant placée de préférence sous ladite partie amovible 31 grâce audit signe visuel 39, comme illustré à la figure 28, a step of placing a ladder 40 against said cold unit 2, as illustrated in FIG. 28 in particular, so that the operator 7 can climb on said ladder so as to approach said platform 6 and reach said part removable 31, said scale 40 being preferably placed under said removable part 31 by virtue of said visual sign 39, as illustrated in FIG. 28,
- une étape de démontage de ladite partie amovible 31 , au cours de laquelle cette dernière est détachée du reste du garde du corps 10 par l’opérateur 7, et par exemple désolidarisée d’une part de ladite partie fixe 33 par enlèvement de ladite goupille 35 et d’autre dudit montant 1 1 en retirant ladite seconde extrémité 38 dudit orifice intermédiaire 30, ladite étape de démontage résultant en l’apparition dudit espace d’accès 32 sous ladite lisse supérieure 12, comme illustré aux figures 22 à 19 et 24 (dans cet ordre), - a step of dismantling said removable part 31, during which the latter is detached from the rest of the bodyguard 10 by the operator 7, and for example detached from one part of said fixed part 33 by removing said pin 35 on the other side of said upright 1 1 by removing said second end 38 of said intermediate orifice 30, said dismantling step resulting in the appearance of said access space 32 under said upper rail 12, as illustrated in Figures 22 to 19 and 24 (in this order),
- une étape d’introduction dudit opérateur 7 sur ladite plate-forme 6, lors de laquelle ce dernier passe, sous ladite lisse supérieure 12, par ledit espace d’accès 32, de façon à accéder à ladite plate-forme 6, ou en d’autres termes à passer de ladite échelle 40 à ladite surface extérieure externe 5, comme illustré à la figure 29, - A step of introducing said operator 7 onto said platform 6, during which the latter passes, under said upper rail 12, through said access space 32, so as to access said platform 6, or by other words to go from said scale 40 to said outer outer surface 5, as illustrated in Figure 29,
- une étape de (re)montage de ladite partie amovible 31 avec le reste dudit garde- corps 10, au cours de laquelle ladite goupille 35 est remise en place pour verrouiller l’emboîtement desdites parties fixe 33 et amovibles 31 et ladite seconde extrémité 38 est réintroduite dans ledit orifice intermédiaire 30, de façon à sécuriser l’opérateur 7 pendant qu’il réalise une intervention de maintenance sur le groupe froid 2, comme illustré aux figures 25, 19 à 22, et 25, - a step of (re) mounting said removable part 31 with the rest of said guardrail 10, during which said pin 35 is put back in place to lock the interlocking of said fixed 33 and removable parts 31 and said second end 38 is reintroduced into said intermediate orifice 30, so as to secure the operator 7 while carrying out a maintenance intervention on the refrigeration unit 2, as illustrated in Figures 25, 19 to 22, and 25,
- une autre étape de démontage de ladite partie amovible 31 , de façon à réaliser ledit espace d’accès 32 pour que l’opérateur 7 puisse quitter ladite plate-forme 6 en repassant, via ledit espace d'accès 32, sur l’échelle 40, - Another step of dismantling said removable part 31, so as to provide said access space 32 so that the operator 7 can leave said platform 6 by going back, via said access space 32, on the ladder 40,
- une autre étape de (re)montage de ladite partie amovible 31 , l’opérateur 7 pouvant ensuite enlever ladite échelle 40 et quitter les lieux en laissant la lisse intermédiaire 25 complète. - Another step of (re) mounting said removable part 31, the operator 7 then being able to remove said ladder 40 and leave the premises, leaving the intermediate rail 25 complete.
De préférence, ledit garde-corps 10 comprend une plinthe 41 reliant lesdits montants 1 1 entre eux, ladite plinthe 41 étant située en-dessous de ladite lisse supérieure 12, plus préférentiellement en-dessous de ladite lisse intermédiaire 25. Plus préférentiellement, ladite plinthe 41 est plaquée contre lesdits montants 1 1. Ladite plinthe 41 présente un chant disposé en regard de, ou directement contre, la périphérie de ladite surface supérieure externe 5. Cette configuration est particulièrement avantageuse pour éviter que l’opérateur 7 tombe de ladite plate-forme 6 par exemple en glissant sous ladite lisse intermédiaire 25, ou qu’il perde ses outils, et notamment ses outils de petite taille (tournevis, etc.) qui pourraient tomber sous ladite lisse intermédiaire 25 en l’absence de ladite plinthe 41 , qui peut donc retenir l’opérateur 7 et/ou son équipement. Ainsi, le procédé de sécurisation comprend avantageusement une étape d’installation d’une plinthe 41 reliant lesdits montants 11 entre eux et située en-dessous de ladite lisse supérieure 12, de préférence en-dessous de ladite lisse intermédiaire 25, ladite étape d’installation comprenant plus avantageusement encore une étape de plaquage de ladite plinthe contre lesdits montants 1 1. Ladite plinthe 41 comprend par exemple des profilés longeant la périphérie de ladite surface supérieure externe 5, ainsi que des renforts de coin 42 à section en L (cf. figure 11) permettant de relier deux desdits profilés au niveau d’un coude dudit garde-corps 10 (et donc d’un coin de ladite plinthe 41), une telle configuration permettant notamment de renforcer ladite plinthe 41 et plus généralement ledit garde-corps 10. Preferably, said guardrail 10 comprises a plinth 41 connecting said uprights 11 together, said plinth 41 being located below said upper rail 12, more preferably below said intermediate rail 25. More preferably, said plinth 41 is pressed against said uprights 1 1. Said plinth 41 has an edge disposed opposite, or directly against, the periphery of said outer upper surface 5. This configuration is particularly advantageous to prevent the operator 7 from falling from said platform. form 6 for example by sliding under said intermediate rail 25, or that it loses its tools, and in particular its small tools (screwdriver, etc.) which could fall under said intermediate rail 25 in the absence of said plinth 41, which can therefore retain the operator 7 and / or his equipment. Thus, the securing method advantageously comprises a step of installing a plinth 41 connecting said uprights 11 to each other and located below said upper rail 12, preferably below said intermediate rail 25, said step of installation still more advantageously comprising a step of plating said plinth against said uprights 11. Said plinth 41 comprises, for example, profiles running along the periphery of said outer upper surface 5, as well as corner reinforcements 42 with an L-section (cf. FIG. 11) making it possible to connect two of said profiles at the level of an elbow of said guardrail 10 (and therefore a corner of said plinth 41), such a configuration making it possible in particular to reinforce said plinth 41 and more generally said guardrail 10.
En outre, certains desdits montants 1 1 , par exemple ceux qui ne sont pas plaqués contre lesdits longerons 19, peuvent éventuellement être équipés chacun d’une embase 43 respective, ladite embase 43 étant elle-même, posée sur et/ou solidarisée à, ladite surface supérieure externe 5, comme illustré notamment à la figure 25. Dans tous les cas, lesdits montants 1 1 , qu’ils soient plaqués contre lesdits longerons 19 ou posés sur ladite surface supérieure externe 5 via ladite embase 43, sont avantageusement reliés, directement ou indirectement, audit châssis 4. In addition, some of said uprights 1 1, for example those which are not pressed against said longitudinal members 19, may optionally each be equipped with a respective base 43, said base 43 itself being placed on and / or secured to, said outer upper surface 5, as illustrated in particular in Figure 25. In all cases, said uprights 11, whether they are pressed against said side members 19 or placed on said outer upper surface 5 via said base 43, are advantageously connected directly or indirectly, to said chassis 4.
Ledit garde-corps 10 comprend de préférence également au moins une équerre de renfort 44 qui est avantageusement reliée de manière permanente à ladite surface supérieure externe 5 d’une part et audit garde-corps 10 d'autre part. De façon avantageuse, ladite équerre de renfort 44 est reliée à la fois à ladite surface supérieure externe 5 et à ladite plinthe 41 et/ou à l’un desdits montants 1 1 , par exemple à l’aide de vis d’un ensemble vis/écrous, ladite équerre de renfort 44 étant par exemple plaquée contre ladite plinthe 41 ou ledit montant 1 1 comme illustré, respectivement, aux figures 1 et 17. Ladite équerre de renfort 44 permet de relier plus fermement encore ledit garde- corps 10 audit châssis 4, augmentant donc la stabilité dudit garde-corps 10 et la sécurité de l’opérateur 7 lorsqu’il se trouve sur ladite plate-forme 6. Said guardrail 10 preferably also comprises at least one reinforcing bracket 44 which is advantageously permanently connected to said outer upper surface 5 on the one hand and to said guardrail 10 on the other hand. Advantageously, said reinforcing bracket 44 is connected both to said outer upper surface 5 and to said plinth 41 and / or to one of said uprights 1 1, for example by means of screws of a screw assembly / nuts, said reinforcing bracket 44 being for example pressed against said plinth 41 or said upright 11 as illustrated, respectively, in Figures 1 and 17.
