Abstract

The method of sealing involves using rubber strips (10) with a profiled section. the wings (11a,b) of the profile are placed respectively between two membranes (16,17) of a bituminous elastomer coupled to the wings by fusion of the adjacent layers of the bituminous material. The lower membranes are pre-welded to the lateral edges (5a,5b) of the expansion band situated below them. The lateral edges of the expansion strips can be glued to the support (2).

Description

La présente invention concerne l'étanchéité de terrasses destinées à la circulation de véhicules automobiles, telles que les parcs automobiles, les aires de déchargement, les voies de circulation, ou les rampes d'accès.The present invention relates to the sealing of terraces intended for the circulation of motor vehicles, such as car parks, unloading areas, traffic lanes, or access ramps.

Elle concerne plus précisément un procédé pour assurer l'étanchéité des joints de dilatation d'une terrasse qui comporte un support constitué de dalles en béton séparées par des joints de dilatation, une couche d'étanchéité recouvrant ledit support et une couche de revêtement au-dessus de la couche d'étanchéité, la couche d'étanchéité comportant notamment des bandes de dilatation en élastomère disposées à cheval au-dessus desdits joints de dilatation, et la couche de revêtement étant fractionnée par des profilés disposés au-dessus desdites bandes d'étanchéité et présentant chacun une partie centrale résiliente disposée au-dessus du joint de dilatation correspondante et deux ailes latérales reposant sur les bords latéraux de la bande d'étanchéité située au-dessous dudit profilé.More precisely, it relates to a method for sealing the expansion joints of a terrace which comprises a support made up of concrete slabs separated by expansion joints, a sealing layer covering said support and a coating layer above it. above the sealing layer, the sealing layer comprising in particular elastomeric expansion bands disposed astride said expansion joints, and the covering layer being divided by sections arranged above said expansion bands sealing and each having a resilient central part disposed above the corresponding expansion joint and two lateral wings resting on the lateral edges of the sealing strip situated below said profile.

Selon les procédés actuels, le profilé est réalisé en aluminium et les ailes du profilé sont fixées par des vis qui traversent les bords latéraux des bandes d'étanchéité en élastomère, afin de prendre appui dans les dalles en béton.According to current methods, the profile is made of aluminum and the wings of the profile are fixed by screws which pass through the lateral edges of the elastomeric sealing strips, in order to bear against the concrete slabs.

Cette disposition n'assure pas une étanchéité parfaite de la terrasse. De plus, les vibrations dues au passage des véhicules sur la surface supérieure des parties centrales résilientes des profilés provoquent des pincements et cisaillements des bandes d'étanchéité en élastomère, qui, avec le temps, portent un préjudice sérieux à la pérennité de l'étanchéité.This arrangement does not ensure perfect sealing of the terrace. In addition, the vibrations due to the passage of vehicles on the upper surface of the resilient central parts of the profiles cause pinching and shearing of the elastomeric sealing strips, which over time seriously damage the durability of the sealing. .

Le but de la présente invention est d'apporter des améliorations décisives au niveau de l'étanchéité des joints de dilatation.The aim of the present invention is to provide decisive improvements in the sealing of the expansion joints.

L'invention atteint son but par le fait que, dans le procédé décrit ci-dessus, l'on utilise des profilés en caoutchouc et par le fait que l'on insère les ailes de profilé respectivement entre deux membranes en bitume élastomère soudées auxdites ailes par fusion des couches adjacentes de bitume, la membrane inférieure en bitume ayant été préalablement soudée au bord latéral de la bande de dilatation située en-dessous.The invention achieves its object by the fact that, in the process described above, rubber profiles are used and by the fact that the profile wings are inserted respectively between two elastomeric bitumen membranes welded to said wings by fusion of the adjacent layers of bitumen, the lower membrane of bitumen having been previously welded to the lateral edge of the expansion band located below.

Grâce au procédé de l'invention, les bandes de dilatation en élastomère ne sont plus percées par des vis. De plus, le souplesse du profil en caoutchouc évite des pincements et écrasements de la bande de dilatation. L'ensemble du profil en caoutchouc dont les ailes sont insérées entre les membranes en bitume élastomère forme un groupe cohérent solidaire de la bande de dilatation en élastomère.Thanks to the method of the invention, the elastomeric expansion bands are no longer pierced by screws. In addition, the flexibility of the rubber profile prevents pinching and crushing of the expansion band. The entire rubber profile, the wings of which are inserted between the elastomeric bitumen membranes, forms a coherent group integral with the elastomeric expansion band.

De préférence, les bords latéraux des bandes de dilatation en élastomère sont collés sur le support.Preferably, the lateral edges of the elastomeric expansion bands are glued to the support.

D'autre part, les membranes en bitume élastomère débordent latéralement à l'extérieur des ailes et sont soudées entre elles par chauffage. Elles sont également soudées par chauffage au complexe bitumineux formant la couche d'étanchéité en dehors des bandes de dilatation en élastomère.On the other hand, the elastomeric bitumen membranes project laterally outside the wings and are welded together by heating. They are also welded by heating to the bituminous complex forming the sealing layer outside the elastomeric expansion bands.

D'autres avantages et caractéristiques de l'invention ressortiront à la lecture de la description suivante faite à titre d'exemple et en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue en perspective et en coupe d'une partie d'une terrasse de circulation réalisée selon le procédé de l'invention ;
  • la figure 2 est une coupe au niveau du joint de dilatation qui montre, à grande échelle, la disposition des différents matériaux constitutifs.
Other advantages and characteristics of the invention will emerge on reading the following description given by way of example and with reference to the appended drawings in which:
  • Figure 1 is a perspective view in section of a portion of a circulation terrace produced according to the method of the invention;
  • Figure 2 is a section at the expansion joint which shows, on a large scale, the arrangement of the various constituent materials.

La référence 1 représente une terrasse destinée à supporter des véhicules automobiles. Cette terrasse 1 comporte un support 2 constitué d'une pluralité de dalles en béton 2a, 2b séparées entre elles par un espace ou un joint de dilatation 3. Au-dessus du support 2 est disposée une couche d'étanchéité 4 qui comporte des bandes de dilatation 5 en élastomère disposées à cheval au-dessus des joints de dilatation 3, et un complexe bitumineux 6 recouvrant, de manière connue, les dalles 2a, 2b en dehors de leurs pourtours, respectivement 7a, 7b, sur lesquels reposent les bords latéraux 5a, 5b des bandes de dilatation 5. La partie centrale 5c des bandes de dilatation 5 se présente sous la forme d'une lyre disposée dans la partie supérieure du joint de dilatation 3.The reference 1 represents a terrace intended to support motor vehicles. This terrace 1 comprises a support 2 consisting of a plurality of concrete slabs 2a, 2b separated from each other by a space or an expansion joint 3. Above the support 2 is disposed a sealing layer 4 which has strips of elastomeric expansion 5 arranged astride the expansion joints 3, and a bituminous complex 6 covering, in known manner, the slabs 2a, 2b outside their edges, respectively 7a, 7b, on which the lateral edges rest 5a, 5b of the expansion bands 5. The central part 5c of the expansion bands 5 is in the form of a lyre arranged in the upper part of the expansion joint 3.

Le rôle des bandes de dilatation 5 est d'assurer l'étanchéité de la couche 4 au-dessus des joints de dilatation 3 quelles que soient les variations de largeur des rigoles 3 par suite des dilatations ou retraits des dalles 2a, 2b. Cest pourquoi les bandes de dilatation 5 sont réalisées en élastomère et présentent une lyre 5c.The role of the expansion bands 5 is to ensure the sealing of the layer 4 above the expansion joints 3 whatever the variations in width of the channels 3 as a result of expansion or shrinkage slabs 2a, 2b. This is why the expansion bands 5 are made of elastomer and have a lyre 5c.

Si le support 2 est constitué d'une pluralité de dalles 2a et 2b disposées bout à bout et côte à côte, des éléments spécifiques en élastomère sont bien entendu prévus à l'intersection des joints de dilatation 3, afin d'assurer la continuité des bandes de dilatation en élastomère 5 au niveau de ces intersections. Ces éléments spécifiques ne sont pas montrés sur les dessins par souci de clarté.If the support 2 consists of a plurality of tiles 2a and 2b arranged end to end and side by side, specific elastomer elements are of course provided at the intersection of the expansion joints 3, in order to ensure the continuity of the elastomeric expansion bands 5 at these intersections. These specific elements are not shown on the drawings for the sake of clarity.

Des profilés 10 sont disposés au-dessus des bandes de dilatation en élastomère 5. Ces profilés 10 présentent une partie centrale 11 résiliente au-dessus d'un joint de dilatation 3 et deux ailes latérales 11a, 11b qui s'étendent à l'horizontale à partir de la base de la partie centrale 11 et recouvrent au moins en partie les bords latéraux 5a, 5b de la bande de dilatation en élastomère 5 située en-dessous. Les profilés 10 sont éventuellement raccordés à des pièces complémentaires en forme de croix au-dessus des intersections des joints de dilatation 3, le cas échéant.Profiles 10 are arranged above the elastomeric expansion bands 5. These profiles 10 have a resilient central portion 11 above an expansion joint 3 and two lateral wings 11a, 11b which extend horizontally from the base of the central part 11 and at least partially cover the lateral edges 5a, 5b of the elastomeric expansion band 5 situated below. The profiles 10 are optionally connected to complementary pieces in the shape of a cross above the intersections of the expansion joints 3, where appropriate.

Un matériau de revêtement 12, de l'asphalte par exemple, recouvre la couche d'étanchéité 4 jusqu'au niveau de la surface supérieure 13 des profilés 10, afin de former la couche de revêtement 14 ou de roulement de la terrasse 1.A coating material 12, for example asphalt, covers the sealing layer 4 up to the level of the upper surface 13 of the profiles 10, in order to form the coating layer 14 or the rolling layer of the terrace 1.

Le rôle du profilé 10 est d'empêcher la couche de revêtement 14 de s'effondrer au-dessus des lyres 5c, et de fractionner la couche de revêtement 14 afin d'éviter des fissures par suite des dilatation.The role of the profile 10 is to prevent the covering layer 14 from collapsing above the lyres 5c, and to split the covering layer 14 in order to avoid cracks due to expansion.

L'ensemble constitué par une bande de dilatation 5 et le profilé 10 situé immédiatement au-dessus constitue un joint de dilatation.The assembly constituted by an expansion band 5 and the profile 10 located immediately above constitutes an expansion joint.

Selon la présente invention, le profilé 10 est réalisé en caoutchouc, de préférence le néoprène. La partie centrale 11 présente des cavités longitudinales 15 disposées de manière à permettre une dilatation transversale tout en assurant une rigidité verticale. Les ailes 11a et 11b présentent des stries sur leurs deux faces et leurs bords sont biseautés.According to the present invention, the profile 10 is made of rubber, preferably neoprene. The central part 11 has longitudinal cavities 15 arranged so as to allow transverse expansion while ensuring vertical rigidity. The wings 11a and 11b have grooves on their two faces and their edges are bevelled.

Afin de solidariser les ailes 11a, 11b d'un profilé 10 respectivement aux bords latéraux 5a, 5b de la bande de dilatation 5 disposée en-dessous, on interpose entre le bord latéral 5a et l'aile 11a, d'une part, et entre le bord latéral 5b et l'aile 11b, d'autre part, des premières membranes en bitume élastomère 16a, 16b qui débordent latéralement au delà de la membrane de dilatation 5 et viennent recouvrir au moins en partie les complexes d'étanchéité 6.In order to secure the wings 11a, 11b of a profile 10 respectively to the lateral edges 5a, 5b of the expansion band 5 disposed below, one interposes between the lateral edge 5a and the wing 11a, on the one hand, and between the lateral edge 5b and the wing 11b, on the other hand, first elastomeric bitumen membranes 16a, 16b which extend laterally beyond the expansion membrane 5 and cover at least in part the sealing complexes 6.

Ces premières membranes 16a et 16b sont soudées par chauffage à la membrane de dilatation 5, aux ailes 11a, 11b du profilé 10 et au complexe d'étanchéité 6.These first membranes 16a and 16b are welded by heating to the expansion membrane 5, to the wings 11a, 11b of the profile 10 and to the sealing complex 6.

Des deuxièmes membranes en bitume élastomère 17a et 17b sont disposées respectivement au-dessus des ailes 11a et 11b. Ces deuxièmes membranes 17a et 17b s'étendent au delà des ailes 11a et 11b et viennent recouvrir au moins en partie les premières membranes 16a et 16b, disposées en-dessous et éventuellement les complexes d'étanchéité 6. Elles sont également soudées par chauffage aux ailes 11a, 11b, aux premières membranes 16a, 16b et le cas échéant au complexe bitumineux 6.Second elastomeric bitumen membranes 17a and 17b are disposed respectively above the wings 11a and 11b. These second membranes 17a and 17b extend beyond the wings 11a and 11b and at least partially cover the first membranes 16a and 16b, arranged below and possibly the sealing complexes 6. They are also welded by heating to wings 11a, 11b, at the first membranes 16a, 16b and, where appropriate, at the bituminous complex 6.

Les premières et deuxièmes membranes 16a, 16b, 17a, 17b se présentent sous forme d'un complexe comportant une couche centrale 18 en élastomère, insérée entre deux couches 19a, 19b en bitume. La fusion du bitume d'une couche extérieure 19a ou 19b permet le soudage avec la bande de matériau en élastomère 5, le profilé 10, ou une autre couche de bitume.The first and second membranes 16a, 16b, 17a, 17b are in the form of a complex comprising a central layer 18 of elastomer, inserted between two layers 19a, 19b of bitumen. The fusion of the bitumen of an outer layer 19a or 19b allows the welding with the strip of elastomer material 5, the section 10, or another layer of bitumen.

Pour parfaire l'étanchéité du joint, les bords latéraux 5a, 5b de la bande d'étanchéité sont collées au moyen d'une colle appropriée 20 sur les pourtours 7a, 7b des dalles 2a, 2b.To complete the sealing of the joint, the lateral edges 5a, 5b of the sealing strip are bonded by means of a suitable adhesive 20 to the edges 7a, 7b of the slabs 2a, 2b.

Le recouvrement des dalles 2a et 2b est réalisé de la manière décrite ci-après.The covering of the slabs 2a and 2b is carried out in the manner described below.

On dépoussière, on sèche, et on applique une couche d'une colle primaire sur les pourtours 7a et 7b des dalles 2a et 2b. La colle peut comporter par exemple 50 % d'un produit vendu sous la dénomination G2000 et 50 % d'un deuxième produit vendu sous la dénomination G500.Dust, dry, and apply a layer of a primary adhesive on the edges 7a and 7b of the slabs 2a and 2b. The glue can for example comprise 50% of a product sold under the name G2000 and 50% of a second product sold under the name G500.

On assemble éventuellement les bandes de dilatation en néoprène 5 avec les éléments spécifiques en élastomère en encollant les deux faces à assembler avec le produit G2000, en les laissant sécher pour que le contact soit "sec au toucher", en assemblant et en marouflant.The neoprene expansion bands 5 are optionally assembled with the specific elastomer elements by gluing the two faces to be assembled with the product G2000, leaving them to dry so that the contact is "dry to the touch", by assembling and marouflaging.

On assemble les bandes de dilatation 5 sur les pourtours 7a, 7b des dalles 2a, 2b en appliquant de la colle 20 sur le support 2 en béton et sur la face interne des bords latéraux 5a, 5b. On attend que la colle 20 soit sèche au toucher, on met en place la bande de dilatation 5 et on maroufle au galet.The expansion bands 5 are assembled on the edges 7a, 7b of the slabs 2a, 2b by applying glue 20 to the concrete support 2 and on the internal face of the lateral edges 5a, 5b. We wait until the glue 20 is dry to the touch, we put in place the expansion band 5 and we roll on with the roller.

On place ensuite les complexes d'étanchéité en bitume 6 sur les dalles 2a, 2b, de manière conventionnelle.The bitumen waterproofing complexes 6 are then placed on the slabs 2a, 2b, in a conventional manner.

On place ensuite, de part et d'autre de la lyre 5c, sur les bords latéraux 5a, 5b des bandes de dilatation 5, les premières membranes 16a, 16b en bitume élastomère, en prenant soin de chauffer la face inférieure des membranes 16a, 16b avec de l'air chaud issu d'un appareil de production d'air chaud. On raccorde les premières membranes 16a, 16b aux complexes d'étanchéité 6 par chauffage au chalumeau.Next, on each side of the lyre 5c, on the lateral edges 5a, 5b of the expansion bands 5, the first membranes 16a, 16b made of elastomeric bitumen, taking care to heat the underside of the membranes 16a, 16b with hot air from a device for producing hot air. The first membranes 16a, 16b are connected to the sealing complexes 6 by heating with a torch.

On raccorde, le cas échéant, les profilés 10 avec les pièces complémentaires en forme de croix.If necessary, the sections 10 are connected with the complementary cross-shaped parts.

On soude les ailes 11a, 11b des profilés 10 en faisant fondre le bitume des couches supérieures des premières membranes 16a, 16b au moyen d'un chalumeau et en posant les profilés 10 sur le bitume en fusion.The wings 11a, 11b of the sections 10 are welded by melting the bitumen of the upper layers of the first membranes 16a, 16b by means of a torch and by placing the sections 10 on the bitumen in fusion.

On pose les deuxièmes membranes 17a, 17b en bitume élastomère de part et d'autre du profilé 10, après avoir fait fondre le bitume de la couche inférieure de ces membranes au moyen d'un chalumeau.The second membranes 17a, 17b are laid in elastomeric bitumen on either side of the profile 10, after having melted the bitumen of the lower layer of these membranes by means of a torch.

Puis, on soude les portions latérales extérieure des deuxièmes membranes 17a, 17b sur les premières membranes 16a, 16b, et éventuellement sur les complexes 6, à l'aide d'un chauffage au chalumeau.Then, the outer lateral portions of the second membranes 17a, 17b are welded on the first membranes 16a, 16b, and optionally on the complexes 6, using a torch heating.
