Definitions

  • the invention relates to a shock absorbing floor for play or sports areas and its manufacturing process.
  • This layer cushioning consists of grains of material elastomer coated with a binder.
  • the elastomeric material may for example be a rubber such as EPDM in the form of aggregates, or come from recovery tires, either by shredding them, or by grating the tread in the form of fibrettes for retreading the carcass of the pneumatic.
  • the binder can be a polyurethane resin single-component or two-component. The proportion of resin can be between 20 and 30% of the mass.
  • this technique poses some problems, essentially linked to the organization of a site for the realization of such a soil.
  • the implementation resin requires climatic conditions restrictive: the temperature must not be lower at a certain threshold, of the order of 10 ° C, so that the resin can polymerize, and the environment must be dry because the resin can react with water. It results from long delays in waiting for good climatic conditions and total polymerization of cushioning soil resin. Outside, deadlines frequently reach a few weeks during which the space intended to receive the cushioning floor is unavailable and must be protected against intrusion.
  • the implementation of the technique must be carried out by qualified personnel for these operations.
  • Another disadvantage is that the amount of resin to use is important.
  • Another technique is to carry out in the factory rectangular or square tiles which will then be placed on a concrete or asphalt support floor to constitute the cushioning floor.
  • These tiles are made with the same materials as before in molds in press. Due to the compression of the materials elastomers in the mold, the interstitial spaces of the aggregates are reduced and the amount of resin can be reduced to about 10% of the mass, which is a economic advantage.
  • these tiles do not have always a good hold on the support floor. Indeed, during the compression of an elastic material, it seeks to extend perpendicular to the effort of compression. This results in local sliding on the ground support. The slab then expands in the horizontal direction and it can also result in localized uplift of the slab.
  • tiles covering which include a material support body hard, such as concrete, covered by a body of covering in flexible and elastic material.
  • This body of coating has a smooth appearance on the upper face. It has support spacers on the underside evenly spaced that rest on the entire surface of the support body.
  • the assembly of the coating on the body support is provided by a peripheral border of the body of coating which surrounds the support body. The border has a return that fits into a rebate formed on the periphery of the support body.
  • Such slabs are juxtaposed to form a floor cushioning. This system also does not leave the possibility of freely adapting the shape of the soil cushioning.
  • the objective of the invention is to remedy these problems by providing a durable cushioning floor whose implementation is simple and possible on various soils supports, and whose forms are free.
  • the ground cushioning is reconstituted so that it is one holding.
  • the invention also relates to a damping floor, characterized in that it is obtained by the process previously described.
  • the shock absorbing floor tiles are interconnected by connecting plates or flexible strips placed under the underlay on either side of a joint between two cushioning floor tiles, the connecting plates being linked to the underlay of each of the slabs.
  • the shock absorbing layer is of the same type as in the prior art, i.e. it is made up elastomer grains coated with a binder. Grip between the cushioning layer and the underlay and the rigidity of the underlay prevents the layer shock absorbing extends longitudinally when people step on it.
  • the floor tile damping thus formed remains very stable for its use, which guarantees its durability.
  • the underlay can be chosen for the underlay, in a function in particular of the compactness and the regularity of the surface of the soil to be covered.
  • Polyurethane foam sheets or extruded polystyrene allow easy absorption of surface irregularities. They could be the sub-layers for floors to be covered with gravel compacted by example.
  • Plywood or particle board panels of wood, as well as polyester resin plates glass-reinforced are better suited for underlayments intended to cover smooth floors made of concrete or asphalt.
  • Non-woven fabric works well also to this type of surface.
  • the layer cushioning is coated with a top coat raincoat.
  • This coating provides the cushioning floor with additional waterproofing qualities, which increases the service life by guaranteeing damping properties of the damping floor slab.
  • the top coat can also allow the choice a color, better mechanical strength of the surface, or improved non-slip qualities.
  • This coating can be a thin layer of polyurethane resin.
  • a damping floor 1 covers an area suitable for the activity that will be exercised on it.
  • a playground has a first play structure supported by feet 13 and a second play structure supported by a base 14.
  • the damping floor 1 comprises, from bottom to top, a rigid underlay 3 of extruded polystyrene, a shock absorbing layer 2 bonded to the underlayer 3, and a polyurethane top coat 4.
  • the sub-layer 3 has for example a thickness of a few centimeters, a density of 25 to 40 kg / m 3 .
  • the shock absorbing layer 2 is of the same type as that described above, namely that it is composed of elastomer grains agglomerated by a resin of polyurethane. Its thickness is also a few centimeters, for example between 2 and 10 centimeters. The thickness is determined by the qualities depreciation that we want to give to the ground cushioning.
  • the glue used is a polyurethane glue single-component or two-component.
  • Finishing layer 4 is a thin layer polyurethane coating.
  • the sub-layer 3 and the shock absorbing layer 2 are made from plates generally rectangular previously manufactured.
  • Moon layers whether it's underlay 3 or layer shock absorber 2 is placed on a manufacturing area by juxtaposing the plates together, so as to cover the entire desired floor area cushioning.
  • this layer is coated with glue and the other layer is placed on the first layer, taking care to offset the joints of a layer to layer.
  • the glue can be distributed evenly discontinuous, in close proximity, or in bands parallel, or even by grid.
  • the songs of damping layer plates are preferably also coated with glue.
  • the underlay 3 is a resin plate glass fiber reinforced polyester (GRP). This plate 3 is either glued to the damping layer 2, or directly poured on it, which also ensures good bond between the two layers 2, 3.
  • GRP resin plate glass fiber reinforced polyester
  • 12 cuts are made in damping soil 1, perpendicular to the surface, preferably along curved lines, to form damping floor tiles 11, as shown on Figure 1.
  • the cuts 12 are made for example with a saw or a blade. If the cushioning floor must include reservations 13, 14, these are also cut out. Preferably at least two 12 cuts go through each reservation, for facilitate the mounting of the cushioning floor thereafter.
  • the dimensions of the slabs 11 are chosen to facilitate handling and transport. We avoid that cutouts 12 do form stars more than three branches to limit the risk of lifting slabs at the connection points.
  • the outer face of the shock absorbing layer of each slab is then coated with a top coat 4.
  • This layer can have a thickness between 0.5 and 3 mm.
  • a link is set up place between the sub-layers 3 of the adjacent slabs 11.
  • This connection can be achieved in different ways. It can be rigid plates 15 glued or stapled on underlayment 3 and evenly distributed along cutouts 12. It can be a flexible strip such than rot-proof fabric or an elastomer sheet, glued or stapled, continuous or discontinuous. In addition, the edges of the tiles can be coated with glue. It is also possible to use staples large dimensions directly connecting the joints between the sub-layers of the slabs.
  • cutouts 12 between slabs go through reservations, so that the tiles can be put in place on either side of element 13, 14 which passes in the reservations.
  • the slabs receive in the workshop flexible strips 16 glued opposite bottom of the under layer 3, on the edge of a single slab along a cutout 12, the other slab along the same cut receiving nothing.
  • the band flexible 12 extends beyond the edge of the slab.
  • the activity area is coated with a cement coating, a nonwoven fabric 17 is deposited over it, preferably having a surface mass from 500 to 900 g / m 2 , then the damping soil is laid on top.
  • the coating completely impregnates the fabric 17 and adheres to the activity area and to the under-layer 3 of the damping soil.
  • the cushioning floor contains, at the periphery, a flexible strip 18 which extends from 20 to 40 cm from the periphery, as shown in Figure 4.
  • the part of the flexible strip which protrudes is buried in the compacted support soil 19 and thus retains the soil cushioning.
  • the flexible strip 18 is permeable, for example in non-woven fabric, for allow the water, which would be under the cushioning soil, to evacuate.
  • the periphery of the cushioning floor can be supplemented by a cushioning in shock absorbing material glued against the edge of the cushioning floor.
  • the edging is either flush with the supporting soil, or buried on a few centimeters or tens of centimeters for better fix the cushioning floor.
  • Layer cushioning can be poured directly onto the underlay, on site or in the workshop.
  • the materials of the shock absorbing layer and underlay are not limited to those cited only as example. They will for example have an elongation before rupture less than 1.5%.
