Description

L'étanchéité et l'isolation sont des propriétés de plus en plus recherchées dans les réalisations de toiture et notamment de toiture de bâtiments industriels. Malheureusement, ces bâtiments sont très souvent recouverts au moyen de plaques ondulées et notamment de plaques en amiante-ciment, de sorte que l'entretien de la couverture, et même sa pose ou celle d'un revêtement isolant, soulèvent des problèmes de sécurité en raison, soit de la fragilité des plaques, soit de la difficulté pour le personnel à se déplacer sur une surface ondulée.Sealing and insulation are properties that are increasingly sought after in the construction of roofs, and in particular the roofing of industrial buildings. Unfortunately, these buildings are very often covered with corrugated sheets and in particular asbestos-cement sheets, so that the maintenance of the roof, and even its installation or that of an insulating coating, raise safety problems in reason, either of the fragility of the plates, or of the difficulty for the personnel to move on a wavy surface.

Il est connu d'après le US-A 4064663 de renforcer par une armature en treillis ou analogue le -iatériau mousse d'isolation d'un abri, mais ce treillis est intercalé entre les couches d'un maté- iau qui repose sur la surface extérieure de la toile constituant l'abri et épouse la forme de cette toi-It is known from US-A 4064663 to reinforce with a lattice frame or the like the foam insulation material of a shelter, but this lattice is interposed between the layers of a material which rests on the outer surface of the fabric constituting the shelter and follows the shape of this roof

La présente invention a pour but de remédier à des inconvénients en fournissant un revêtement :e couverture facile à réaliser qui présente une resistance suffisante pour supporter le personnel j'exécution ou d'entretien, ainsi qu'une surface plane quel que soit le support sur lequel il est place.The object of the present invention is to remedy drawbacks by providing a coating: an easy-to-produce cover which has sufficient strength to support the personnel performing or maintaining it, as well as a flat surface whatever the support on which it is placed.

Cette invention a en effet pour objet un revêtement de couverture isolant et étanche réalisé in situ qui comporte une plaque de matériau mousse, plate et d'épaisseur sensiblement constante, sette plaque adhérant à un support le long de lignes espacées DE-A-2613157, caractérisé en ce que la plaque est composée d'un matériau mousse se solidifiant presque instantanément et adhère directement et uniquement à des saillies du support formant lesdites lignes espacées et en ce qu'une armature de renforcement et de rigidifica- lion ayant des mailles suffisamment fines pour retenir la majeure partie du produit moussant, encore à l'état liquide, jusqu'à sa solidification, est noyée dans la plaque.The subject of this invention is in fact an insulating and waterproof covering coating produced in situ which comprises a plate of foam material, flat and of substantially constant thickness, this plate adhering to a support along spaced lines DE-A-2613157, characterized in that the plate is made of a foam material which solidifies almost instantaneously and adheres directly and only to protrusions of the support forming said spaced lines and in that a reinforcement and stiffening reinforcement having sufficiently fine meshes to retain most of the foaming product, still in the liquid state, until it solidifies, is embedded in the plate.

Selon le bâtiment auquel le revêtement est destiné, le support peut être constitué par des piaques ondulées déjà mises en place sur la toiture, la plaque de matériau mousse adhérant aux crêtes des ondulations de ces plaques, ou être fixé directement sur les pannes, ou autres éléments de la toiture.Depending on the building for which the covering is intended, the support may consist of corrugated plates already placed on the roof, the sheet of foam material adhering to the crests of the corrugations of these sheets, or be fixed directly to the purlins, or the like. elements of the roof.

Dans tous les cas, le revêtement permet une circulation sans danger par le personnel d'entretien ou d'exécution, l'armature assurant à la fois une surface extérieure plane et une résistance mécanique suffisante.In all cases, the coating allows safe circulation by maintenance or execution personnel, the reinforcement ensuring both a flat external surface and sufficient mechanical resistance.

Selon un mode de réalisation, l'armature comporte deux nappes: une nappe inférieure à mailles fines de retenue du matériau mousse et de rigidification de la plaque, et une nappe supérieure à mailles larges assurant la résistance mécanique de l'ensemble.According to one embodiment, the frame comprises two plies: a lower ply with fine meshes for retaining the foam material and stiffening the plate, and an upper ply with wide meshes ensuring the mechanical strength of the assembly.

L'invention s'étend également à un procédé de fabrication de ce revêtement de toiture caractérisé en ce qu'il consiste à placer une armature plate et tendue, ayant des mailles suffisamment fines pour retenir la majeure partie d'une produit moussant encore à l'état liquide jusqu'à sa solidification, sur un support fixe comportant des saillies formant des lignes espacées et parallèles entre elles, et à déposer sur cette armature un produit moussant, liquide, qui se solidifie presque instantanément en adhérant uniquement et directement aux saillies du support après avoir mouillé la face inférieure de l'armature, et gonfle autour de cette dernière pour constituer une plaque plane.The invention also extends to a method of manufacturing this roof covering, characterized in that it consists in placing a flat and taut reinforcement, having meshes sufficiently fine to retain the major part of a foaming product still at liquid state until solidification, on a fixed support comprising projections forming spaced and parallel lines between them, and depositing on this frame a foaming, liquid product, which solidifies almost instantaneously by adhering only and directly to the projections of the support after wetting the underside of the frame, and swells around the latter to form a flat plate.

On obtient ainsi un revêtement étanche et isolant, qui peut être exécuté et entretenu en toute sécurité, et qui peut aussi bien être formé sur un bâtiment en construction qu'être adapté sur un bâtiment existant, notamment pour transformer une toiture ondulée en toiture à surface plane.A waterproof and insulating coating is thus obtained, which can be executed and maintained in complete safety, and which can be formed on a building under construction as well as being adapted on an existing building, in particular for transforming a corrugated roof into a surface roof. plane.

La description ci-dessous d'un mode de réalisation donné à titre d'exemple non limitatif, et représenté sur les dessins annexés, fera d'ailleurs ressortir les avantages et caractéristiques de l'invention. Sur ces dessins:

  • la fig. 1 est une vue en perspective, arrachée, d'une portion de revêtement de couverture selon l'invention;
  • la fig. 2 est une vue en coupe verticale, suivant la ligne 2-2 de la fig. 1;
  • la fig. 3 est une vue analogue à la fig. 2, d'une variante de réalisation;
  • la fig. 4 est une vue analogue à la fig. 2, d'un revêtement de couverture posé directement sur les pannes de la toiture.
The description below of an embodiment given by way of nonlimiting example, and represented in the accompanying drawings, will moreover highlight the advantages and characteristics of the invention. In these drawings:
  • fig. 1 is a perspective view, cut away, of a portion of covering covering according to the invention;
  • fig. 2 is a view in vertical section, along line 2-2 of FIG. 1;
  • fig. 3 is a view similar to FIG. 2, of an alternative embodiment;
  • fig. 4 is a view similar to FIG. 2, a covering covering placed directly on the purlins of the roof.

Comme le montre la fig. 1, le revêtement de couverture objet de l'invention comporte des plaques ondulées 1, qui sont fixées de la manière habituelle sur des pannes, mais dont la fixation n'a pas été représentée pour ne pas compliquer le dessin. Sur les crêtes 2 de ces plaques ondulées est posée une nappe d'armature 4 qui est formée, par exemple, par un treillis, une grille, du métal déployé, ou même un tissu de verre. Cette nappe a des mailles de dimension relativement faibles, par exemple des mailles carrées de 6 mm de côté, et elle est tendue de façon à être rigoureusement plane.As shown in fig. 1, the covering covering object of the invention comprises corrugated plates 1, which are fixed in the usual way on purlins, but the fixing of which has not been shown so as not to complicate the drawing. On the ridges 2 of these corrugated plates is placed a reinforcing ply 4 which is formed, for example, by a lattice, a grid, expanded metal, or even a glass cloth. This ply has relatively small meshes, for example square meshes with a side of 6 mm, and it is stretched so as to be strictly flat.

Au-dessus de la nappe 4 est placee une seconde nappe 6 ayant des mailles de grandes dimensions, par exemple des mailles carrées de 10 cm de côté. Cette seconde nappe est constituée, par exemple, par des plaques de treillis soudé, du métal déployé, une tôle perforée. une grille, un caillebotis, nervurés ou non, un filet piastique ou autres, présentant une grande résistance mécanique.Above the ply 4 is placed a second ply 6 having large meshes, for example square meshes with a side of 10 cm. This second layer consists, for example, of welded mesh plates, expanded metal, a perforated sheet. a grid, a grating, ribbed or not, a piastic net or others, with great mechanical resistance.

Les deux nappes 4 et 6 sont noyées dans un matériau mousse 8, qui adhère aux crêtes 2 de la plaque ondulée 1, et constituent une armature de renforcement de ce matériau. Le produit moussant est, par exemple, un polyuréthane, un poly- carbonate, un polyurée, présentant de bonnes qualités d'adhérence au support 1 et capable de se solidifier très rapidement autour des nappes 4 et 6 en présentant une surface extérieure 9 réellement plane.The two plies 4 and 6 are embedded in a foam material 8, which adheres to the ridges 2 of the corrugated plate 1, and constitute a reinforcement of this material. The foaming product is, for example, a polyurethane, a polycarbonate, a polyurea, having good qualities of adhesion to the support 1 and capable of solidifying very quickly around the sheets 4 and 6 by presenting an exterior surface 9 which is really flat. .

Ce revêtement selon l'invention est d'ailleurs formé sur place. Après la fixation des plaques ondulées 1 sur les pannes 20, la nappe à mailles fines 4 est d'abord posée sur les crêtes 2 de la plaque 1 et tendue de manière à former une surface rigoureusement plane, puis la seconde nappe 6 est posée sur la première et le produit moussant, à l'état liquide, est déposé sur les deux nappes. Ce produit se solidifie presque instantanément, en fait en deux ou trois secondes, de sorte qu'il est solidifié avant d'avoir eu le temps d'at- teindre les creux 10 des ondes de la plaque ondulée 1, et forme seulement en-dessous de la nappe 4 une mince couche 12 (fig. 2) qui adhère étroitement aux sommets 2 des crêtes de la plaque 1.This coating according to the invention is also formed on site. After the corrugated plates 1 have been fixed to the purlins 20, the fine-mesh ply 4 is first placed on the ridges 2 of the plate 1 and stretched so as to form a strictly flat surface, then the second ply 6 is placed on the first and the foaming product, in the liquid state, is deposited on the two layers. This product solidifies almost instantaneously, in fact in two or three seconds, so that it solidifies before having had time to reach the valleys 10 of the waves of the corrugated plate 1, and only forms in- below the tablecloth 4 a thin layer 12 (fig. 2) which adheres closely to the vertices 2 of the ridges of the plate 1.

Bien entendu, les mailles fines de la nappe 4 sont suffisamment grandes pour permettre à une partie du liquide de les traverser avant que la solidification ne se produise, mais cependant suffisamment petites pour limiter cette pénétration du liquide à la couche mince 12 et empêcher le liquide de s'écouler librement en direction des creux d'onde 10. Ces mailles doivent avoir entre 5 et 20 mm. Un espace ou poche d'air 21 est alors laissé libre dans chaque creux d'onde, entre la plaque 1 et la mousse armée 8 du revêtement, ce qui améliore le coefficient d'isolation.Of course, the fine meshes of the sheet 4 are large enough to allow part of the liquid to pass through them before solidification occurs, but nevertheless small enough to limit this penetration of the liquid into the thin layer 12 and prevent the liquid to flow freely towards the troughs of wave 10. These meshes must have between 5 and 20 mm. An air space or pocket 21 is then left free in each wave trough, between the plate 1 and the reinforced foam 8 of the coating, which improves the insulation coefficient.

Les dimensions des mailles de la seconde nappe 6, de même que le matériau qui constitue cette nappe, sont choisis de manière à donner à cette dernière une résistance mécanique importante, de sorte qu'elle est susceptible de supporter des charges relativement élevées et notamment un personnel d'exécution ou d'entretien.The dimensions of the meshes of the second ply 6, as well as the material which constitutes this ply, are chosen so as to give the latter a high mechanical resistance, so that it is capable of supporting relatively high loads and in particular a operating or maintenance personnel.

Le revêtement obtenu assure ainsi non seulement la couverture étanche et isolante de la toiture, mais également la sécurité du personnel qui le pose ou l'entretient.The coating obtained thus ensures not only the waterproof and insulating covering of the roof, but also the safety of the personnel who installs or maintains it.

Selon une variante de réalisation, représentée sur la fig. 3, les deux nappes 4 et 6 sont confondues et rénunies en une seule, 16, qui repose sur l'ensemble des crêtes d'ondulation de la plaque 1 et est, comme les nappes 4 et 6, noyée dans un produit mousse 18 dont elle constitue l'armature. La nappe 16 assure à la fois la rigidification du revêtement et la retenue du produit liquide, tout en donnant à l'ensemble une résistance mécanique importante qui lui permet de supporter des charges lourdes tout en restant plane. Cette armature 16 peut, par exemple, être en un métal déployé nervuré ou en toile de verre, ce qui permet de réaliser le revêtement à un moindre coût. Dans un mode de mise en oeuvre particulièrement avantageux, on utilise un treillis en toile de verre plastifié à haute résistance ayant les caractéristiques suivantes:

  • - poids: 350 g/m2
  • - Rr (résistance à la rupture): 20 kg/cm
  • - maille: (5x5) mm2
  • - coefficient de transparence: 30%.
According to an alternative embodiment, shown in FIG. 3, the two layers 4 and 6 are combined and united into a single one, 16, which rests on all of the corrugation ridges of the plate 1 and is, like the layers 4 and 6, embedded in a foam product 18 of which it constitutes the framework. The ply 16 ensures both the stiffening of the coating and the retention of the liquid product, while giving the assembly a high mechanical strength which allows it to withstand heavy loads while remaining flat. This frame 16 may, for example, be made of a ribbed expanded metal or glass cloth, which allows the coating to be produced at a lower cost. In a particularly advantageous embodiment, a mesh of high-strength plasticized glass fabric having the following characteristics is used:
  • - weight: 350 g / m 2
  • - Rr (breaking strength): 20 kg / cm
  • - mesh: (5x5) mm 2
  • - transparency coefficient: 30%.

Ce treillis est à mailles assez larges pour que le liquide moussant passe au travers et puisse ainsi mouiller les dessus des supports sur lesquels la mousse va s'accrocher par collage. Cependant, les mailles sont assez fines pour qu'à la projection, il ne passe que très peu de liquide moussant qui serait perdu pour la réalisation du revêtement.This trellis has a mesh wide enough for the foaming liquid to pass through and can thus wet the tops of the supports on which the foam will hang by gluing. However, the meshes are fine enough that at the projection, there passes very little foaming liquid which would be lost for the realization of the coating.

Ainsi:

  • 1. On limite la perte de produit moussant qui passe au travers du treillis, à une quantité minime qui, dans le cas de la couverture fibre-ciment, vient se déposer en creux d'onde.
  • 2. Le produit moussant passe quand même en quantité suffisante au travers du treillis pour que l'ensemble du revêtement ainsi formé soit adhérent sur les crêtes du support sans aucune adjonction de colle préalable.
  • 3. Le treillis ainsi enrobé par le produit moussant peut lors de l'expansion monter dans la première couche de mousse pour se situer à coeur de celle-ci et ainsi participer à la résistance mécanique de l'ensemble.
So:
  • 1. The loss of foaming product which passes through the mesh is limited to a minimal quantity which, in the case of fiber-cement roofing, is deposited in the hollow of the wave.
  • 2. The foaming product still passes in sufficient quantity through the trellis so that the entire coating thus formed is adherent to the ridges of the support without any addition of prior adhesive.
  • 3. The mesh thus coated with the foaming product can during expansion go up in the first layer of foam to be located at the heart thereof and thus participate in the mechanical strength of the assembly.

Dans ce mode de réalisation, comme dans le précédent, l'ensemble de la plaque 8 munie de l'armature de renforcement constituée par les nappes 4 et 6 ou par la seule nappe 16, est suffisamment rigide pour ne reposer sur le support formé par la plaque ondulée 1 que le long des crêtes 2, c'est-à-dire le long de lignes espacées entre elles. Il est clair, par suite, qu'une telle plaque de mousse armée peut également être portée par d'autres types de support. Par exemple, comme le montre la fig. 4, elle peut être fixée directement sur les pannes successives 20, 22 d'une toiture et constituer la couverture à elle seule. Une armature 24, comportant une ou plusieurs nappes de renforcement, est alors tendue directement sur les pannes 20, 22 et noyée dans le produit mousse 28 qui se solidifie autour d'elle en adhérant au sommet de chacune des pannes 20, 22. Grâce à l'armature 24 la face extérieure de la couverture est plane et l'ensemble présente une rigidité suffisante et assure une isolation et une étanchéité efficaces.In this embodiment, as in the previous one, the whole of the plate 8 provided with the reinforcing reinforcement constituted by the plies 4 and 6 or by the single ply 16, is rigid enough not to rest on the support formed by the corrugated plate 1 only along the ridges 2, that is to say along lines spaced apart. It is clear, therefore, that such a reinforced foam plate can also be carried by other types of support. For example, as shown in fig. 4, it can be fixed directly to the successive purlins 20, 22 of a roof and constitute the cover by itself. A frame 24, comprising one or more reinforcing plies, is then stretched directly over the purlins 20, 22 and embedded in the foam product 28 which solidifies around it by adhering to the top of each of the purlins 20, 22. Thanks to the frame 24 the outer face of the cover is flat and the assembly has sufficient rigidity and provides effective insulation and sealing.

Bien entendu, une ou plusieurs couches supplémentaires de produit moussant peuvent être projetées sur la plaque mousse armée 8,18, 28, si nécessaire, pour donner au revêtement l'épaisseur appropriée.Of course, one or more additional layers of foaming product can be sprayed onto the reinforced foam plate 8, 18, 28, if necessary, to give the coating the appropriate thickness.

Dans tous les cas le revêtement est facile à mettre en ceuvre. La plaque de produit moussant 8, 18 ou 28 est en effet formée à partir d'éléments plans, qui n'ont besoin d'être fixés que localement sur leur support. Ce revêtement est particulièrement avantageux pour la protection des toitures ondulées et notamment pour transformer une couverture ondulée en couverture à surface plane. Il permet ainsi de profiter non seulement des qualités du revêtement lui-même, mais également d'une réduction de surface développée et donc de flux thermique pour une même épaisseur d'isolant, tout en améliorant l'aspect extérieur.In all cases the coating is easy to implement. The foaming product plate 8, 18 or 28 is in fact formed from planar elements, which need only be fixed locally on their support. This coating is particularly advantageous for the protection of you wavy tures and in particular to transform a corrugated blanket into a flat surface blanket. It thus makes it possible to take advantage not only of the qualities of the coating itself, but also of a reduction in developed area and therefore in heat flux for the same thickness of insulation, while improving the external appearance.

En outre, avec un volume de matériau réduit par rapport à celui habituellement nécessaire sur les couvertures ondulées, on obtient une régularité d'épaisseur très nettement améliorée, c'est-à-dire une meilleure qualité d'isolation avec un coût diminué.In addition, with a reduced volume of material compared to that usually required on corrugated roofing, a regularity of thickness is very much improved, that is to say a better quality of insulation with a reduced cost.

Enfin, dès la mise en place de l'armature, et à tout moment par la suite, la sécurité de la circulation est assurée.Finally, as soon as the frame is put in place, and at any time thereafter, traffic safety is ensured.

An insulating and fluidtight roof covering constructed on the site, comprising a flat sheet of foam material (8, 18, 28) having a substantially constant thickness, this sheet (8,18, 28) adhering to a support (1, 20) along spaced-apart lines, characterised in that the sheet is composed of a foam material (8, 18, 28) which solidifies almost instantaneously and directly and solely adheres to projections of the support (1, 20) forming said spaced-apart lines, and a reinforcing and stiffening element (4, 16, 24) having meshes which are sufficiently fine for retaining the major part of the foaming product, still in the liquid state, until its solidification, is embedded in the sheet (8. 18,28)
2. A covering according to claim 1. characterised in that the reinforcing element (4, 16. 24; comprises meshes of between 5 and 20 mm.
3. A covering according to one of the claims 1 and 2, characterised in that the reinforcing element (4, 16, 24) comprises a lower layer (4) having fine meshes retaining the liquid foaming product, and an upper layer (6) having large meshes having sufficient mechanical strength for ensuring safety of circulation.
4. A covering according to one of the claims 1 and 2, characterised in that the reinforcing element is formed by a single layer (16) forming a form bottom and ensuring the strength and made from a material such as ribbed expanded metal or a glass cloth.
5. A covering according to claim 3, characterised in that the first layer is constituted by a net of metal, a glass cloth or the like, while the second layer is formed by sheets of welded lattice, expanded metal, a perforated sheet, a netting, a grating, a plastic net orthe like;
6. A covering according to one of the preceding claims, characterised in that the support is constituted by corrugated roof sheets (1), the foam material adhering to the corrugation crests (2).
7. A covering according to one of the claims 1 to 5, characterised in that the support is formed by a succession of roofing purlins (20, 22).
8. A method for manufacturing a roofing covering according to one of the preceding claims, characterised in that it consists in placing a flat and taut reinforcing (4, 16, 24) having meshes which are sufficiently fine to retain the major part of a foaming product still in the liquid state until its solidification on a fixed support (1, 20) comprising projections forming spaced apart and parallel lines, and depositing on this reidorc- ing element a liquid foaming product which is solidified almost instantaneously by adhering solelv and directly to the projections (2) of the support after having wetted the lower surface of the reinforcing element and inflated around the latter, so as to constitute a planar sheet.
9. A method according to claim 8, characterised in that one or a plurality of other layers of foaming product is projected onto the reinforced planarfoam sheet (8, 16, 28).
