Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • the aim of the present invention is to provide decisive improvements in the sealing of the expansion joints.
  • 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.
  • the elastomeric expansion bands are no longer pierced by screws.
  • the flexibility of the rubber profile prevents pinching and crushing of the expansion band.
  • the lateral edges of the elastomeric expansion bands are glued to the support.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the assembly constituted by an expansion band 5 and the profile 10 located immediately above constitutes an expansion joint.
  • 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.
  • first elastomeric bitumen membranes 16a, 16b which extend laterally beyond the expansion membrane 5 and cover at least in part the sealing complexes 6.
  • 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.
  • 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.
  • 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.
  • 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.
  • the covering of the slabs 2a and 2b is carried out in the manner described below.
  • 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.
  • 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.
  • 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.
  • bitumen waterproofing complexes 6 are then placed on the slabs 2a, 2b, in a conventional manner.
  • 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.
  • the sections 10 are connected with the complementary cross-shaped parts.
  • 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.
  • 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.
  • 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.
