Definitions

  • the present invention relates to a composite bituminous sheet, usable in particular for sealing elements.
  • coated reinforcements for example based on felt cardboard, glass cloth, glass veil, polyester non-woven, etc.
  • These coated reinforcements are used alone or combined with one another by superposition within a sealing sheet.
  • the elastic properties are very low and the elongation under low or high stress does not exceed approximately 50%.
  • sealing sheets are used on supports made of masonry, insulating materials, etc., having flat surfaces, in general, or very simple geometric shapes.
  • the width of the formed joint can increase or decrease, depending on climatic conditions or by mechanical stresses.
  • the sealing function is ensured by the variation of the geometric shape of the sheet folded in bellows in the lyre, and this without the need to lengthen the sheet.
  • the general functioning is similar, but the variable geometric shape is very complex.
  • the techniques most commonly used to date consist in manufacturing a plaster or a waterproof coating in situ, by coating a square of glass cloth with a bituminous sealant based on solvent, the solvent used to thin the sealant.
  • the object of the invention is to remedy the drawbacks of the previous methods and to provide a device which adapts to all shapes and dimensions of seals and which can be produced quickly and easily, by traditional means, without resorting to no solvent.
  • Its subject is a composite bituminous sheet usable in particular for sealing elements, composed of a reinforcing cloth coated with a bituminous composition, characterized in that it consists of an external zone formed of a practically cloth non-stretchable under low stress surrounding at least one central zone formed of an elastic and stretchy fabric having an elongation at break in tension at least equal to 100% whatever the direction of the stress, the whole being coated with the same bituminous composition with high elongation at break having a softening point in the standardized Ball and Ring test at least equal to 100 ° C.
  • the subject of the invention is therefore a bituminous sheet consisting of two zones each comprising a reinforcement of a different type.
  • the main or external zone is formed of a canvas of mineral or organic fibers practically non-extensible under low stress, and the central zone consists of a stretch canvas under low stress and elastic, the two zones being coated with the same bituminous binder, this binder consisting of a bituminous composition with high elongation at break having a softening point in the standardized ball and ring test at least equal to 100 ° C.
  • central area is meant here an area placed in the sheet so as to be completely surrounded by the outer area to which it is fixed. In the same sheet, there can be several central zones separated from each other.
  • the main or external area is, as we have just indicated, made from a canvas that is practically non-stretchable under low stress; this fabric, the minimum mass of which is preferably at least 50 g / m 2 , can for example be made of glass fibers, polyamide or polyester. It will advantageously have a mechanical tensile strength at least equal to 10 daN / cm in width in the longitudinal direction and in the transverse direction.
  • the central zone is formed by an elastic fabric which can be extended in all directions, which can advantageously be obtained by knitting natural fibers (jute, etc.) and / or synthetic fibers such as polyamide or polyester fibers.
  • its minimum mass will preferably be of the order of 50 g / m 2.
  • Its tensile strength is advantageously greater than a few deca-newtons per centimeter (in particular of the order of 4) mainly for manufacturing reasons and to allow implementation without particular and restrictive precautions.
  • the fabrics forming the external zone and the central zone or zones are coated with the same bituminous mass having a high elongation at break and a softening point in the ball and ring test, according to French standard NF T 66008, at least equal to 100 ° C.
  • Its elongation at break will advantageously be greater than or equal to 500%.
  • the cold flexibility of the bituminous coating mass is important and can go down to - 15 ° C without rupture, by winding in 5 s on a mandrel of 20 mm in diameter (according to the test described in the standard French NF P 84303.
  • bituminous coating composition it is possible to use, for example, bitumen / SBS mixtures (styrene / butadiene elastomer / triblock styrene) and, preferably, mixtures of BPS type.
  • BPS bitumen is a bituminous composition which was described in the patent application in France No 78.26336 of the holder, filed on September 13, 1978.
  • the bitumen is for example a direct or oxidized distillation bitumen, having a penetration between 40 and 220;
  • the polyolefin can be a polypropylene, a polybutylene, a propylene / ethylene copolymer or a propylene / ethylene / butylene copolymer, and the elastomer is in particular a styrene / butadiene copolymer having a molecular weight of between 100,000 and 300,000 approximately.
  • This BPS composition can also contain a filler and / or a pigment and / or a flame retardant.
  • the table indicates the properties desired for the composite sheet according to the invention and for its various zones.
  • the procedure is preferably carried out as follows.
  • one or more zones are cut which will form the central zones.
  • pieces of a size at least equal to that of the cuts made in the first sheet are cut.
  • the non-extensible fabric was previously coated in a conventional manner by means of a coating machine, or another system, with the desired bituminous composition.
  • the pieces of coated stretch fabric, for their part, are centered on the holes made in the coated non-stretch sheet, and the elements are made integral by welding either along the edges or by covering, the bituminous composition serving to ensure the junction between the central zone and the external zone.
  • central area could be attached to the outer area along its edges by other known means, if desired.
  • the reinforcement is imposed on the reinforcement in the order of 50% in all directions and the fibers are coated by spraying the bituminous composition or by dipping therein at a temperature of 180 to 200 ° C. This gives a flat bituminous sheet of regular thickness and, subsequently, during application, there is a certain dimensional shrinkage, by action of the temperature, which is favorable for use.
  • FIGS. 1 and 5 represent different types of sealing elements obtained from the composite sheet according to the invention
  • FIG. 6 shows such a sealing element put in place at a crossing of joints.
  • Figs. 1 and 2 represent cut pieces of rectangular shape.
  • the external zone is represented by the reference 1 and the central zone by the reference 2.
  • FIG. 2 there is also shown a rectangular element comprising an external zone 3 and two central zones 4.
  • Fig. 3 represents a cross-shaped element, in which the external zone 5 surrounds a central zone 6.
  • Fig. 4 represents a T-shaped element, in which the external zone 7 surrounds a central zone 8 disposed approximately at the intersection of the branches of the T.
  • fig. 5 represents an L-shaped element, with an external zone 9 surrounding a central zone 10 placed approximately at the meeting point of the branches of the L.
  • Fig. 6 illustrates the application of a sealing element according to the invention of square shape at the crossing of two seals.
  • the sealing sheets of the seals are represented by the references 11, 12, 13 and 14, and the sealing element 15 according to the invention is applied to the crossing of the seals, over the ends of the sealing sheets, so that its central zone 16 is arranged at the intersection of the two joints and can, by its extensible nature, be applied tightly to the grooves of the joints.
  • the edges of the external zone 17 of the sealing element are fixed in a known manner to the ends of the sealing sheets of said seals.
  • the laying technique used is practically the same; it consists in performing a flame welding of a torch on the bituminous supports of the joints.
  • sealing elements according to the invention for the treatment of an intersection between a horizontal joint and a vertical joint, the depth of the joints as well as their opening being able to be different and variable.
  • Static punching (according to French standard NF P 84352): more than 22 kg on the perlite-based insulating panel.
  • a polyamide knitted fabric is coated using the same BPS bituminous composition as above.
  • the coated sheet obtained has the following characteristics:
  • Static punching more than 12 kg on the perlite-based insulating panel.
  • the BPS bituminous composition used has the following composition:
