Description

       

  LE MINISTRE DES AFFAIRES ECONOMIQUES ET DES CLASSES MOYENNES,

  
Vu la loi du 30 mars 1948, portant modification à l'arrêté-loi du 8 juillet 1946, prorogeant, en raison des événements de guerre, les délais en matière de propriété industrielle et la durée des brevets d'invention.

  

 <EMI ID=1.1> 


  
Vu l'arrêté-loi du 8 juillet 1946, prorogeant en raison des événements de guerre, les délais en matière de propriété industrielle et la durée des brevets d'invention, modifié par la loi du 30 mars 1948;

  
Vu la Convention d'Union pour la Protection de la Propriété Industrielle; 

  
" Panneau isolant et ses procédés et appareillages de fabrication ".

  
La présente invention a pour objet un procédé

  
de fabrication de panneaux destinés plus particulièrement à absorber les sons et les variations de température,ces panneaux étant perforés selon des normes qui seront développées p lus loin.

  
L'invention concerne également un appareillage nouveau permettant de fabriquer commodément , rapidement et avantageusement certains de ces panneaux, de façon que ces derniers présentent des caractéristiques entièrement nouvelles.

  
Le brevet couvre enfin les produits industriels nouveaux constitués par les panneaux eux-mêmes, tels qu'ils sont obtenus selon le procédé et à partir de

  
 <EMI ID=2.1>  On connaît certains dispositifs de fabrication

  
de panneau;; isolants obtenus en coulant des corps tels que le plâtre ou le ciment dans des moules prévus à cet effet. De tels panneaux ont été également réalises avec différents raciaux tels que le fer ou l'aluminium, ou avec des matériau:; tels que le fibre-ciment, le contreplaqué , le bois reconstitue, etc.

  
Un propres considérable fut réalise plus récemment lorsque l'on fabriqua des panneaux en plâtre, en staff ou en ciment, constituant des panneaux perforés, enrobant un matelas de laine de verre interposé entre eux; mais la réalisation pratique de tels panneaux souffrait encore

  
de l'obligation où l'on était de couler le plâtre ou

  
le ciment sans ennober complètement le matelas intermé-

  
 <EMI ID=3.1> 

  
toujours difficile.

  
Enfin les perferations de panneaux telles que celles déjà réalisées par la demandeur ou obtenues selon d'autres dispositifs, mettaient en contact le matelas intérieur de laine de verre, papier-carton, feutre léger, fibres diverses, etc .. avec l'atmosphère.

  
Les panneaux obtenus selon la présente invention peuvent posséder des perforations sur un seul côté ou sur les deux côtés; ces perforations peuvent, soit atteindre le matelas fibreux intérieur, soit, au contraire,conserver, entre ce matelas et l'autre épaisseur, un diaphragme de plâtre ou de ciment dont la minceur pourra être réglée.

  
On sait que l'existence de tels diaphragmes renforce la variété d'absorption acoustique du panneau, ses possibilités décoratives, de protection et d'entretien.

  
Quant au procédé et à l'appareillage permettant d'ob-

  
tenir ces panneaux, ils sont tels que l'on peut s'assurer

A 

  
une fabrication satisfaisante dans des moules horizontaux ou verticaux selon les exigences du moulage des diffirents corps, ceux exigeant par exemple un vibrage.

  
En sus des caractéristiques nouvelles qui viennent d'être exposées, le procédé et l'appareillage qui vont être décrits permettent d'obtenir des panneaux offrant cette caractéristique essentielle d'enrober complètement, dans la matière coulée un panneau de fibre (par exemple

  
du feutre) préalablement armé et, au besoin, imperméabilisé, et de telle sorte que son armature lui assure un coefficient de solidité et, en plus, l'élasticité, particulièrement avantageux en matière d'absorption sonore.

  
Sur les dessins ci-contre, on a représenté à titre d'exemple non limitatif deux modes de réalisation de l'invention ; on voit :

  
 <EMI ID=4.1> 

  
tion d'un panneau dans un moule horizontal, le moule étant ouvert.

  
la Fig. 2,/ perspective d'un moule vertical de fab rication, le couvercle du moule étant enlevé. Fig. 3 une coupe verticale transversale du moule <EMI ID=5.1>  Fig. 3bis, variante de la figure 3. Fig. 4, la perspective d'un panneau obtenu selon le procédé décrit à la figure 3. <EMI ID=6.1>  ceptibles d'être fermés par un verrouillage 3 de façon à emboîter une base 4 munie de poignées de manoeuvre 12 et
12'; cette base peut porter des saillies 5, tronconiques ou en ellipsoïdes tronquées, l'expérience ayant démontré l'avantage de cette dernière forme pour l'acoustique, le nettoyage, et pour la fixation sur la surface

  
n des panneaux des ceintures, substances ou enduits de revêtement des cloisons; certains de ces enduits sont

  
plus particulièrement destinés a améliorer l'acoustique des salles, de sorte que la forme des saillies 5 constitue un élément original supplémentaire , perfectionnant

  
la sonorisation des locaux.

  
Un couvercle (non représenté) lui-même pourvu de saillies analogues aux saillies 5, est sur la boîte ainsi préparée après qu'on y a coulé le produit destiné

  
à constituer le panneau, par exemple du ciment ou du plâtre.

  
Ce dernier (ou leur mélange avec des produits tels que la pouzzolane) formera donc un panneau présentant,

  
sur une ou deux faces, des perforations correspondant aux saillies 5.

  
En outre, on aura la possibilité de couler d'abord

  
le produit en quantité suffisante pour noyer les saillies et en recouvrir les sommets d'une mince pellicule dont l'épaisseur pourra varier au gré du fabricant. Sur ce coulage pourra être posée une plaque de feutre, de laine de verre, etc.. par dessus laquelle sera coulé enfin le

  
reste du produit, de façon à remplir la boîte dans laquelle sera replacé le couvercle . Au déboîtage, on obtiendra une panneau enrobant complètement la plaque fibreuse intérieure et percé de logettes qui pourront ne pas atteindre cette plaque fibreuse, ou au contraire arriver jusqu'à elle.

  
Il sera possible même de fabriquer un tel panneau avec des perforations n'atteignant pas le matelas fibreux intérieur, et dont certaines seulement seront ensuite terminées à la gouge automatique.

  
On pourrait encore assurer à la fabrication des perforations dont certaines seulement resteraient borgnes,

  
n en donnant aux saillies de la boîte et du couvercle des longueurs différentes.

  
On voit, sur les figures 2, 3 et 3bis (moule vertical), une base 6 supportant deux grandes cloisons verticales

  
 <EMI ID=7.1> 

  
parallélipipède rectangle dans lequel sera coulé le plâtre, ciment, etc.. Les panneaux 7 et 7' pourront posséder des saillies 5 à l'instar des panneaux 4 et de la figure 1; ces saillies bénéficieront des mêmes caractéristiques que les précédentes quant à leur forme, leur profil et leur longueur, et un couvercle 8 sera prévu éventuellement pour parachever le moulage s'il y a lieu .

  
Dans certain moule analogue précédemment connu, avec lequel sont fabriqués des panneaux tels que ceux dont il a été question, dans le préambule, une âme parallélipipédique était prévue dans les moules, de façon à laisser subsister au démoulage une cavité destinée à recevoir le matelassage intérieur fibreux.

  
Selon la présente invention, cette âme est démontable de façon à pouvoir être remplacée par le feutre armé luimême. Ce feutre 9 peut, en effet, être soutenu par une

  
 <EMI ID=8.1> 

  
façon à assurer au matelas 9 la tension requise . Ce matelas est placé avant que le plâtre ne soit coulé, et peut être maintenu à la hauteur voulue par des tiges 11 pouvant jouer le rôle de scellement ou d'étrésillons d'une face à l'autre du panneau . Ces matelas pourront être traités chimiquement suivant les besoins et usages envisagés, par des produits imperméabilisants, ignifugeants, désinfectants, etc..

  
On voit que l'on obtient ainsi un panneau enrobant entièrement le matelas fibreux et creusé de logettes

  
de profil et de profondeur répondant aux exigences de l'acoustique et de l'isolation.

  
Le nombre et l'emplacement de ces lo&#65533;ettes peuvent également varier selon les types de panneaux; elles pourront, par exemple, être plus grandes ou plus nombreuses par unité de surface dans certains cas; certaines pourront être voilées par un diaphragme soit d'un côté, soit de l'autre, soit même partiellement sur un même panneau.

  
Le panneau ainsi fabriqué constitue un produit industriel nouveau nettement caractérisé; il pourra être utilisé pour former une cloison simple ou double par des panneaux plaças parallèlement l'un par rapport à l'autre, et reliés par des scellements ou des entretoises, selon que l'espace séparant les panneaux parallèles doit rester vide ou être comblé par un remplissage quelconque (lainage souple, laine de verre, etc..) . Dans le cas de l'utilisation de panneaux ainsi jumelés, on constate que l'absorption de son est quasi complète, les ondes sonores étant renvoyées d'un panneau

  
à l'autre et absorbées par les logettes décrites cidessus.

  
La fabrication des panneaux peut se faire dans des moules en aluminium, en tôle, en ciment armé ou en toute autre matière appropriée.

  
Les exemples qui viennent d'être décrits pourront recevoir des modifications mineures ne sortant pas du cadre de l'invention ; ces modifications pourront porter notamment sur :

  
1) Les dimensions, et principalement l'épaisseur

  
des cloisons des panneaux;

  
 <EMI ID=9.1> 

  
mensions des perforations;

  
3) L'épaisseur des diaphragmes, ou la suppression de certains d'entre eux;

  
4) L'épaisseur du matelas fibreux et de son armature;

  
5) L'utilisation des panneaux, isolément ou par/' paires ;

  
6) L'incorporation dans le produit coulé, de tous les matériaux appropriés, tels que la. pouzzolane, la dolomie et les poudres de pierres analogues.

  
Grâce aux moules ainsi constitués, le problème du vibrage des panneaux ou carreaux en béton se trouve résolu, principalement quand on utilise un matelas

  
de laine de verre ou autre matière isolante, absorbante, souple, et formant ressort sous la pression du béton en cours de roulage . Il suffira, en effet, de couvrir les faces perforées (qui ont tendance à se gonfler au démoulage) de plaques d'un poids calculé pour compenser la poussée du matelas de verre ou feutre équivalent.

  
Si ces plaques compensatrices sont perforées, elles peuvent recouvrir toute la surface du panneau . Si elles ne le sont pas, il suffit de laisser la série des trous inférieurs ou supérieurs non couverts. Ce procédé permet de façonner la face perforée sans déformations au séchage.

  
Un processus analogue peut enfin être adapté avec avantage si l'on désire incorporer à certains panneaux des éléments de renforcement, ou simplement décoratifs tels que notamment les gravillons de dolomie, de marbre, de porphyre, etc.. Dans ce cas, la plaque 4 portant

  
des saillies 5 et servant de support de base, est tout d'abord noyée sous une première couche de béton. Sur celle-ci vient s'appliquer le voile en laine de verre, portant sur sa face supérieure son support, de préférence imperméable (papier, carton, etc..) . Intervient alors

  
le coulage de la seconde couche de béton, qui est lissée et vibrée, et dans laquelle on incorpore les gravillons choisis, pendant ou en fin de vibrage . Ceux-ci, soit par le lissage, soit par la vibration, seront entièrement pris dans la masse de bétons-seuls ceux de la zone limite



  THE MINISTER OF ECONOMIC AFFAIRS AND MIDDLE CLASSES,

  
Considering the law of March 30, 1948, amending the decree-law of July 8, 1946, extending, because of the events of war, the deadlines in matters of industrial property and the duration of patents for invention.

  

 <EMI ID = 1.1>


  
Considering the decree-law of July 8, 1946, extending due to the events of war, the deadlines in matters of industrial property and the duration of invention patents, modified by the law of March 30, 1948;

  
Having regard to the Union Convention for the Protection of Industrial Property;

  
"Insulating panel and its manufacturing processes and equipment".

  
The present invention relates to a method

  
for manufacturing panels intended more particularly to absorb sound and temperature variations, these panels being perforated according to standards which will be developed further.

  
The invention also relates to a new apparatus making it possible to conveniently, quickly and advantageously manufacture some of these panels, so that the latter have entirely new characteristics.

  
Finally, the patent covers new industrial products made up of the panels themselves, as obtained by the process and from

  
 <EMI ID = 2.1> Some manufacturing devices are known

  
panel ;; insulators obtained by pouring bodies such as plaster or cement into molds provided for this purpose. Such panels have also been made with different races such as iron or aluminum, or with materials :; such as fiber cement, plywood, reconstituted wood, etc.

  
A considerable amount of work was carried out more recently when plaster, staff or cement panels were manufactured, constituting perforated panels, covering a mattress of glass wool interposed between them; but the practical realization of such panels still suffered

  
of the obligation to cast the plaster or

  
cement without completely coating the intermediate mattress

  
 <EMI ID = 3.1>

  
always difficult.

  
Finally, the perferations of panels such as those already produced by the applicant or obtained according to other devices, brought the inner mattress of glass wool, paper-cardboard, light felt, various fibers, etc. into contact with the atmosphere.

  
The panels obtained according to the present invention can have perforations on one side or on both sides; these perforations can either reach the internal fibrous mat, or, on the contrary, keep, between this mat and the other thickness, a diaphragm of plaster or cement, the thinness of which can be adjusted.

  
It is known that the existence of such diaphragms reinforces the variety of acoustic absorption of the panel, its decorative possibilities, protection and maintenance.

  
As for the process and the apparatus for obtaining

  
hold these panels, they are such that we can ensure

AT

  
satisfactory manufacture in horizontal or vertical molds according to the molding requirements of the various bodies, those requiring for example vibration.

  
In addition to the new characteristics which have just been explained, the process and the apparatus which will be described make it possible to obtain panels offering this essential characteristic of completely coating a fiber panel in the cast material (for example

  
felt) previously reinforced and, if necessary, waterproofed, and in such a way that its reinforcement gives it a coefficient of solidity and, in addition, elasticity, particularly advantageous in terms of sound absorption.

  
In the drawings opposite, two embodiments of the invention have been shown by way of nonlimiting example; we see :

  
 <EMI ID = 4.1>

  
tion of a panel in a horizontal mold, the mold being open.

  
Fig. 2, / perspective of a vertical manufacturing mold, the mold cover being removed. Fig. 3 a transverse vertical section of the mold <EMI ID = 5.1> Fig. 3a, variant of FIG. 3. FIG. 4, the perspective of a panel obtained according to the process described in FIG. 3. <EMI ID = 6.1> able to be closed by a locking 3 so as to fit a base 4 provided with operating handles 12 and
12 '; this base can bear protrusions 5, frustoconical or truncated ellipsoids, experience having demonstrated the advantage of the latter form for acoustics, cleaning, and for fixing to the surface

  
n panels of the belts, substances or coatings of the partitions; some of these plasters are

  
more particularly intended to improve the acoustics of rooms, so that the shape of the projections 5 constitutes an additional original element, perfecting

  
sound system for the premises.

  
A cover (not shown) itself provided with projections similar to the projections 5, is on the box thus prepared after the product intended for it has been poured.

  
to form the panel, for example cement or plaster.

  
The latter (or their mixture with products such as pozzolana) will therefore form a panel presenting,

  
on one or two sides, perforations corresponding to the projections 5.

  
In addition, we will have the opportunity to sink first

  
the product in sufficient quantity to flood the projections and cover the tops with a thin film, the thickness of which may vary at the discretion of the manufacturer. On this casting can be placed a sheet of felt, glass wool, etc., over which will finally be poured the

  
rest of the product, so as to fill the box in which the cover will be replaced. When stripping, a panel will be obtained which completely surrounds the internal fibrous plate and pierced with compartments which may not reach this fibrous plate, or on the contrary reach it.

  
It will even be possible to manufacture such a panel with perforations which do not reach the inner fibrous mat, and only some of which will then be finished with an automatic gouge.

  
We could still ensure the manufacture of perforations, only some of which would remain blind,

  
n by giving the protrusions of the box and the cover different lengths.

  
We see, in Figures 2, 3 and 3a (vertical mold), a base 6 supporting two large vertical partitions

  
 <EMI ID = 7.1>

  
rectangular parallelepiped in which the plaster, cement, etc. will be poured. The panels 7 and 7 'may have projections 5 like the panels 4 and in FIG. 1; these protrusions will benefit from the same characteristics as the previous ones as to their shape, their profile and their length, and a cover 8 will possibly be provided to complete the molding if necessary.

  
In a certain previously known similar mold, with which panels such as those in question are made, in the preamble, a parallelepipedal core was provided in the molds, so as to leave a cavity for demolding the interior padding. fibrous.

  
According to the present invention, this core is removable so that it can be replaced by the reinforced felt itself. This felt 9 can in fact be supported by a

  
 <EMI ID = 8.1>

  
so as to provide the mattress 9 with the required tension. This mattress is placed before the plaster is poured, and can be maintained at the desired height by rods 11 which can play the role of sealing or struts from one face to the other of the panel. These mattresses can be chemically treated according to the needs and uses envisaged, with waterproofing, flame-retardant, disinfectant products, etc.

  
We see that we thus obtain a panel completely enveloping the fibrous mat and hollowed out of cubicles

  
profile and depth meeting the requirements of acoustics and insulation.

  
The number and location of these tiles may also vary depending on the types of panels; they may, for example, be larger or more numerous per unit area in certain cases; some may be veiled by a diaphragm either on one side or the other, or even partially on the same panel.

  
The panel thus manufactured constitutes a clearly characterized new industrial product; it can be used to form a single or double partition by panels placed parallel to each other, and connected by seals or spacers, depending on whether the space between the parallel panels must remain empty or be filled by any filling (soft wool, glass wool, etc.). In the case of the use of panels thus paired, it is noted that the absorption of sound is almost complete, the sound waves being returned from a panel

  
to the other and absorbed by the cubicles described above.

  
The manufacture of the panels can be done in aluminum molds, sheet metal, reinforced cement or any other suitable material.

  
The examples which have just been described may receive minor modifications which do not go beyond the scope of the invention; these modifications may relate in particular to:

  
1) The dimensions, and mainly the thickness

  
partitions of panels;

  
 <EMI ID = 9.1>

  
measurements of perforations;

  
3) The thickness of the diaphragms, or the elimination of some of them;

  
4) The thickness of the fibrous mat and its reinforcement;

  
5) The use of panels, singly or in pairs;

  
6) Incorporation in the cast product of all suitable materials, such as. pozzolan, dolomite and similar stone powders.

  
Thanks to the molds thus formed, the problem of vibrating concrete panels or tiles is solved, mainly when a mattress is used.

  
of glass wool or other insulating material, absorbent, flexible, and forming a spring under the pressure of the concrete during rolling. It will suffice, in fact, to cover the perforated faces (which tend to swell on demolding) with plates of a weight calculated to compensate for the thrust of the glass or equivalent felt mat.

  
If these compensating plates are perforated, they can cover the entire surface of the panel. If they are not, it is sufficient to leave the series of lower or upper holes uncovered. This process makes it possible to shape the perforated face without deformation on drying.

  
A similar process can finally be adapted with advantage if it is desired to incorporate reinforcing elements, or simply decorative elements, such as in particular dolomite, marble, porphyry, etc. chippings, etc. In this case, plate 4 wearing

  
of the projections 5 and serving as a base support, is first of all embedded under a first layer of concrete. On this is applied the glass wool veil, carrying on its upper face its support, preferably waterproof (paper, cardboard, etc.). Then intervenes

  
the pouring of the second layer of concrete, which is smoothed and vibrated, and in which the chosen chippings are incorporated, during or at the end of the vibration. These, either by smoothing or by vibration, will be entirely taken up in the mass of concrete - only those of the limit zone
