Abstract
Description
La présente invention concerne des perfectionnements apportés aux tours d'étaiement utilisées dans le bâtiment ou les travaux publics pour le soutien temporaire d'éléments de construction pesants (plancher, travée de pont, ...), et elle concerne plus particulièrement des perfectionnements apportés à certains éléments constitutifs de ces tours d'étaiement pour assurer une sécurité efficace du personnel aussi bien lors du montage/démontage qu'en exploitation.The present invention relates to improvements made to the shoring towers used in the building or public works for temporary support heavy construction elements (floor, span bridge, ...), and it relates more particularly to improvements made to certain constituent elements of these shoring towers to ensure safety efficient staff as well during assembly / disassembly than in operation.
Actuellement, les tours d'étaiement sont équipées de croisillons qui sont solidarisés aux montants verticaux et qui n'offrent pas de sécurité suffisante pour le personnel, ni lors du montage de la tour d'étaiement, ni lors de son utilisation.Shoring towers are currently equipped braces which are secured to the vertical uprights and which do not provide sufficient security for the personnel, neither during the erection of the shoring tower, nor when in use.
La tour d'étaiement peut également être équipée, notamment en supplément des croisillons précités, de lisses horizontales qui, certes, peuvent assurer le rôle de garde-corps une fois montées, mais dont le montage ne s'effectue pas dans les conditions de sécurité requises.En outre, l'indépendance des lisses vis-à-vis des croisillons entraíne des manipulations additionnelles et allonge la durée des opérations de montage/démontage.The shoring tower can also be equipped, in particular in addition to the aforementioned crosspieces, horizontal beams which, of course, can play the role of railings once assembled, but whose assembly does not does not take place under the required security conditions. in addition, the independence of the beams from the cross bars causes additional manipulations and lengthens the duration of assembly / disassembly operations.
Enfin, on connaít des garde-corps à montage indépendant de celui des croisillons qui n'offrent cependant pas une sécurité suffisante en exploitation. En outre leur indépendance des croisillons nécessite des manipulations supplémentaires et allonge les étapes de montage/démontage.Finally, we know mounting railings independent of that of the braces which do not offer however not sufficient safety in operation. In in addition to their independence from the braces requires additional manipulations and lengthens the stages of assembly / disassembly.
L'invention a essentiellement pour but de proposer une structure perfectionnée qui offre la sécurité requise non seulement en exploitation, mais aussi lors du montage/démontage et qui par ailleurs soit agencée de manière à simplifier les conditions de stockage, de transport et de montage/démontage du matériel et à conduire à une sensible accélération du montage/démontage.The object of the invention is essentially to propose an advanced structure that provides the required security not only in operation, but also during assembly / disassembly and which is also arranged in order to simplify the storage conditions, transport and assembly / disassembly of equipment and lead to a significant acceleration of assembly / disassembly.
A ces fins, l'invention propose un ensemble croisillon garde-corps pour tour d'étaiement comprenant :
- un croisillon comportant un premier et un second barreau en X articulés en rotation à leur intersection, les extrémités inférieures et supérieures respectives des deux barreaux étant agencées pour leur solidarisation à des montants verticaux de la tour d'étaiement, et
- une traverse supérieure dont une extrémité est solidaire en rotation de l'extrémité supérieure du premier barreau et dont l'autre extrémité est solidarisable de façon amovible à l'extrémité supérieure du second barreau.
- a crosspiece comprising a first and a second X-shaped bar articulated in rotation at their intersection, the respective lower and upper ends of the two bars being arranged for their attachment to the vertical uprights of the shoring tower, and
- an upper cross member, one end of which is rotatably attached to the upper end of the first bar and the other end of which is detachably secured to the upper end of the second bar.
Grâce à ces dispositions structurelles, ledit ensemble peut occuper deux positions fonctionnelles, à savoir :
- une position de montage dans laquelle la traverse est
solidarisée à l'extrémité supérieure du second barreau
en maintenant les deux barreaux dans leur conformation
en X, ledit ensemble pouvant alors être solidarisé aux
montants verticaux de la tour d'étaiement par les
extrémités inférieures et supérieures desdits barreaux,
la traverse constituant une lisse supérieure,
et - une position de stockage et de transport dans laquelle la traverse est désolidarisée de l'extrémité supérieure du second barreau et les deux barreaux et la traverse sont repliés les uns contre les autres en un faisceau.
- a mounting position in which the cross member is secured to the upper end of the second bar while maintaining the two bars in their X-shaped configuration, said assembly can then be secured to the vertical uprights of the shoring tower by the lower and upper ends said bars, the cross member constituting an upper rail,
and - a storage and transport position in which the cross member is detached from the upper end of the second bar and the two bars and the cross member are folded against one another in a bundle.
Pour faciliter le montage correct de l'ensemble (fixation de la traverse au second barreau du croisillon en position de lisse et montage des quatre extrémités du croisillon sur les montants de la tour d'étaiement), on prévoit avantageusement que les moyens de solidarisation situés à l'extrémité supérieure du second barreau comprennent une patte saillante percée d'une lumière oblongue.To facilitate the correct assembly of the assembly (fixing the crosspiece to the second cross bar in smooth position and mounting of the four ends of the crosspiece on the uprights of the shoring tower), advantageously provides that the means of securing located at the upper end of the second bar include a protruding leg pierced with an oblong light.
Pour faciliter les conditions de stockage et de transport du matériel, les premier et second barreaux comportent des moyens de solidarisation intermédiaires distants de leurs extrémités supérieures respectives et situés en des emplacements respectifs tels que, dans la position de stockage et de transport dans laquelle les deux barreaux et la traverse sont repliés les uns contre les autres, l'extrémité libre de la traverse est solidarisable simultanément auxdits moyens de solidarisation intermédiaires des deux barreaux, ce grâce à quoi les deux barreaux et la traverse sont bloqués dans leur position repliée les uns contre les autres. Dans ce cas, il est avantageux que lesdits moyens de solidarisation intermédiaires comprennent deux pattes saillantes percées chacune d'une lumière et prévues respectivement sur les deux barreaux.To facilitate storage and storage conditions transport of equipment, the first and second bars include intermediate securing means distant from their respective upper ends and located in respective locations such as in the storage and transport position in which two bars and the cross are folded against each other the others, the free end of the cross member can be secured simultaneously with said securing means intermediaries of the two bars, thanks to which the two bars and crosspiece are locked in their position folded against each other. In this case, it is advantageous that said intermediate securing means include two protruding tabs each pierced of a light and provided respectively on the two bars.
Pour compléter la protection conférée, en position de montage, par la lisse supérieure formée par la traverse assemblée au croisillon, on peut prévoir que les deux barreaux soient pourvus de parties saillantes respectives disposées entre leur articulation mutuelle et leurs extrémités supérieures respectives et conformées de manière que, en position de montage, ces deux parties saillantes forment ensemble une sous-lisse. Dans un mode de réalisation simple, chaque partie saillante est constituée par un tronçon allongé (tube, fer plat ou en L) coudé en L solidarisé au barreau respectif.To complete the protection conferred, in position mounting, by the top rail formed by the cross assembled at the cross, we can predict that the two bars are provided with respective projecting parts arranged between their mutual articulation and their respective and shaped upper ends of so that, in the mounting position, these two parts protruding together form a sub-smooth. In a mode of simple realization, each projecting part is consisting of an elongated section (tube, flat iron or L) angled in L fixed to the respective bar.
Grâce aux dispositions conformes à l'invention, on constitue un ensemble regroupant trois éléments constitutifs principaux (deux barreaux et une traverse) qui sont propres à constituer un croisillon garde-corps offrant toutes les conditions de sécurité requises pour le personnel en exploitation. Au surplus, lors du montage, l'ensemble est préparé dans sa conformation d'exploitation soit au sol, soit à un étage inférieur de la tour d'étaiement, puis mis en place de là (contreventement à lancement) alors que le personnel de montage se trouve à un emplacement sécurisé.Thanks to the arrangements according to the invention, we constitute a set of three elements main components (two bars and a cross member) which are suitable for constituting a railing cross offering all the security conditions required for the operating personnel. In addition, during assembly, the whole is prepared in its operating conformation either on the ground or on a lower floor of the tower shoring, then set up from there (bracing launch) while the assembly personnel are at a secure location.
En outre, du fait de l'inséparabilité de ces trois éléments principaux, on est assuré de toujours disposer, lors du stockage, du transport et du montage/démontage, de l'ensemble complet sans risque de perte de pièces.In addition, due to the inseparability of these three main elements, we are sure to always have, during storage, transport and assembly / disassembly, the complete set without risk of losing parts.
On notera au surplus que la conformation repliée de l'ensemble simplifie notablement les conditions de stockage et de transport de ce matériel.Note also that the folded conformation of the set significantly simplifies the conditions of storage and transport of this material.
Enfin, et il ne s'agit pas là d'un moindre avantage, le coût d'un ensemble croisillon garde-corps conforme à l'invention n'est pas excessif en regard, d'une part, des coûts individuels respectifs des deux barreaux du croisillon et de la traverse formant lisse qui doivent de toute façon entrer dans la constitution de la tour d'étaiement et, d'autre part, de l'amélioration des conditions de montage/démontage et de l'amélioration des conditions de sécurité au cours de ces étapes.Finally, and this is not a lesser advantage, the cost of a railing brace set according to the invention is not excessive with regard to a share of the respective individual costs of the two bars crosspiece and cross member forming a smooth anyway get into the constitution of the tower shoring and, secondly, improving conditions of assembly / disassembly and improvement of security conditions during these steps.
L'invention sera mieux comprise à la lecture de la description détaillée qui suit d'un mode de réalisation préféré donné uniquement à titre d'exemple non limitatif. Dans cette description, on se réfère aux dessins annexés sur lesquels :
- la figure 1 est une vue schématique de côté d'un ensemble croisillon garde-corps pour tour d'étaiement agencé conformément à l'invention, montré en position de montage ;
- la figure 2 est une vue schématique de côté de l'ensemble de la figure 1 montré en position repliée pour son stockage et/ou son transport ; et
- la figure 3 est une vue schématique en perspective d'une tour d'étaiement en cours de montage/démontage, avec l'ensemble de la figure 1 montré en cours d'installation/désinstallation.
- Figure 1 is a schematic side view of a cross guard rail assembly for shoring tower arranged in accordance with the invention, shown in the mounting position;
- Figure 2 is a schematic side view of the assembly of Figure 1 shown in the folded position for storage and / or transport; and
- Figure 3 is a schematic perspective view of a shoring tower during assembly / disassembly, with the assembly of Figure 1 shown during installation / uninstallation.
En se reportant tout d'abord à la figure 1, un ensemble croisillon garde-corps agencé conformément à l'invention, et désigné dans son ensemble par la référence 1, comprend :
- un
premier barreau 2 et unsecond barreau 3 disposés en X (croisillon), qui sont articulés en rotation à leur intersection en 4 (approximativement en leur milieu) ; leurs extrémités respectives, inférieures et supérieures, sont agencées pour leur solidarisation à des montants verticaux de la tour d'étaiement, comme cela sera expliqué plus loin ; typiquement, les 2, 3 sont des tronçons tubulaires métalliques à extrémités aplaties (écrasement du tube) et percées debarreaux lumières 5 propres à être engagées sur des doigts saillants prévus sur les montants verticaux; - une
traverse 6 supérieure dont une extrémité 7 est solidaire à rotation en 9 de l'extrémité supérieure de l'un des barreaux (premier barreau 2 sur la figure 1) et dont l'autreextrémité 8 est solidarisable de façon amovible à l'extrémité supérieure de l'autre barreau (second barreau 3 sur la figure 1).
- a
first bar 2 and asecond bar 3 arranged at X (cross), which are articulated in rotation at their intersection at 4 (approximately in the middle); their respective ends, lower and upper, are arranged for their attachment to vertical uprights of the shoring tower, as will be explained below; typically, the 2, 3 are metallic tubular sections with flattened ends (crushing of the tube) and pierced withbars holes 5 suitable for being engaged on projecting fingers provided on the vertical uprights; - an
upper cross member 6, one end 7 of which is rotationally integral at 9 with the upper end of one of the bars (first bar 2 in FIG. 1) and theother end 8 of which is detachably removable at the end top of the other bar (second bar 3 in Figure 1).
Grâce à cet agencement, l'ensemble 1 est propre à occuper deux positions fonctionnelles :
- une position de montage illustrée à la figure 1, dans
laquelle la
traverse 6 est solidarisée à l'extrémité supérieure dusecond barreau 3 en maintenant ainsi lesdits 2, 3 dans leur conformation en X (croisillon), ledit ensemble ainsi préformé pouvant alors être solidarisé aux montants verticaux de la tour d'étaiement par les extrémités inférieures et supérieures des deuxbarreaux 2, 3, labarreaux traverse 6 formant une lisse supérieure,
et - une position repliée de stockage et/ou de transport
illustrée à la figure 2, dans laquelle la
traverse 6 est désolidarisée de l'extrémité supérieure dusecond barreau 3, et les deux 2, 3 et labarreaux traverse 6 sont repliés les uns contre les autres sous forme d'un faisceau de trois tubes accolés, peu encombrant et facile à manipuler.
- a mounting position illustrated in FIG. 1, in which the
cross-member 6 is secured to the upper end of thesecond bar 3, thus maintaining said 2, 3 in their X-shaped configuration (cross), said assembly thus preformed then being able to be secured to the vertical uprights of the shoring tower by the lower and upper ends of the twobars 2, 3, thebars cross-member 6 forming an upper rail,
and - a folded position for storage and / or transport illustrated in FIG. 2, in which the
cross-member 6 is detached from the upper end of thesecond bar 3, and the two 2, 3 and thebars cross-member 6 are folded against each other others in the form of a bundle of three joined tubes, compact and easy to handle.
Pour que l'ensemble 1 soit à la fois simple à
fabriquer, aisé à manipuler et mécaniquement résistant, on
prévoit d'avoir recours aux dispositions complémentaires
qui suivent.So that the
Les extrémités supérieures respectives des deux
barreaux 2, 3 sont équipées de deux pattes respectives 10,
11, d'étendue radiale, qui sont percées. La patte 10 du
barreau 2 supporte, par l'intermédiaire d'une vis
d'assemblage ou analogue, l'extrémité 7 de la traverse 6,
de façon à constituer un assemblage rotatif. La lumière 12
de la patte 11 du barreau 3 est propre à recevoir une vis
d'assemblage ou analogue traversant une lumière dans
l'extrémité 8 de la traverse 6. Avantageusement la lumière
12 est oblongue, comme visible à la figure 2, de manière à
conférer un jeu limité propre à faciliter l'accrochage en
cinq points de l'ensemble 1 (un point d'accrochage de la
traverse 6 sur le barreau 3 et quatre points d'accrochage
des barreaux 2, 3 sur les montants verticaux de la tour
d'étaiement) .The respective upper ends of the two
Pour que l'ensemble 1 en position repliée (figure
2) conserve sa conformation en faisceau de tube de façon
sûre, on prévoit une patte 13 sur l'un des barreaux (par
exemple le barreau 3) en un emplacement tel que cette
patte 13, percée, tombe en alignement avec la lumière de
l'extrémité 8 de la traverse 6. Une vis d'assemblage ou
analogue solidarise les deux pièces.So that the
Avantageusement, les deux barreaux 2, 3 sont
pourvus de parties saillantes respectives disposées entre
leur articulation 4 et leurs extrémités supérieures
respectives et conformées de manière que, dans la position
de montage illustrée à la figure 1, ces deux parties
saillantes constituent ensemble une sous-lisse complétant
la fonction de garde-corps entre la lisse supérieure
constituée par la traverse 6 et les portions inférieures
des barreaux 2, 3 écartées l'une de l'autre. De façon
simple, chaque partie saillante peut être constituée par
un tronçon allongé 14 (par exemple tronçon tubulaire, fer
plat ou en L, ...) coudé en L et solidarisé (notamment
soudé) au barreau respectif : on constitue une sous-lisse,
discontinue, qui complète efficacement la protection dans
la zone du croisillon où les deux barreaux 2, 3 convergent
l'un vers l'autre.Advantageously, the two
A la figure 3 est illustrée une tour d'étaiement
en cours de montage. Cette tour, en général de contour
rectangulaire, comprend quatre montants 15 verticaux
entretoisés qui reposent inférieurement sur des vérins à
vis 16 respectifs et qui se terminent supérieurement, une
fois la tour achevée, par des vérins à vis de support de
poutres de soutien (non montrés). Dans l'exemple illustré,
deux montants 15 sont solidarisés par des barres 17
horizontales, pour constituer des structures de panneaux
en échelle E qui sont superposés pour former deux faces
opposées de la tour.In Figure 3 is illustrated a shoring tower
during assembly. This tower, usually in outline
rectangular, includes four
Les panneaux en échelle E, qui sont classiquement
entretoisés par des croisillons, sont ici entretoisés par
des ensembles croisillon garde-corps 1 conformes à
l'invention comme visible à l'étage inférieur, déjà
installé, visible à la figure 3. Les deux ensembles
croisillon garde-corps 1 de l'étage inférieur sont mis en
place par l'installateur depuis le sol, en positionnant
les lumières 5 précitées des extrémités des barreaux 2, 3
sur les doigts saillants visibles en 18 sur les montants
15 (les parties 14 formant sous-lisses n'ont pas été
illustrées pour rendre le dessin mieux lisible).E-scale panels, which are conventionally
braced by braces, are here braced by
Un plancher 19 est alors installé et l'installateur
20, monté sur ce plancher, est protégé par la lisse
6 pour procéder à l'installation des panneaux en échelle E
de l'étage au-dessus et des ensembles croisillon garde-corps
1 correspondants. A la figure 3, l'installateur a
déployé un ensemble 1 pour le mettre dans sa conformation
de montage et est en train de positionner cet ensemble sur
les montants 15 en commençant par loger les deux lumières
5 supérieures sur les doigts correspondants.A floor 19 is then installed and the
Une fois le deuxième étage monté, un plancher 19 est installé plus haut et, depuis le deuxième étage, l'installateur monte le troisième étage dans les mêmes conditions de sécurité, et l'opération se poursuit jusqu'à l'achèvement de la tour.Once the second floor is installed, a floor 19 is installed higher and, from the second floor, the installer climbs the third floor in the same security conditions, and the operation continues until completion of the tower.
Grâce aux dispositions conformes à l'invention,
l'installateur travaille toujours en sécurité, aussi bien
au montage qu'au démontage de la tour. Il faut souligner
que cette sécurité résulte de pièces essentielles
constitutives de la tour d'étaiement et que, du fait de
l'intégration structurelle de la traverse 6 avec les deux
barreaux 2, 3 du croisillon, il n'est pas possible de
construire la tour d'étaiement sans que les pièces de
sécurité (lisses, éventuellement sous-lisses) y soient
nécessairement intégrées.Thanks to the arrangements according to the invention,
the installer always works safely, as well
during assembly and disassembly of the tower. You need to underline
that this security results from essential parts
of the shoring tower and that, due to
structural integration of
