The existing factory-prefabricated elastic terrace is a coiled material, is manufactured and molded at one time according to the application environment, has a plane surface and a plane bottom surface, and is used after being bonded with the ground through an adhesive and dried on site. The bottom of prefabricated elasticity terrace is full area contact with ground, and the main problem of mating formation is that the roughness requirement on ground is very high, and if there is the bulging or unsmooth ground, causes the middle bulging or the scheduling problem that sticks up of elasticity terrace easily when mating formation.

For example, chinese patent publication No. CN202730588U discloses a runway coiled material, which has increased adhesive force by adding contact area between the lower surface of the wear-resistant surface layer and the upper surface of the elastic bottom layer and glue on the lower surface of the wear-resistant surface layer and elasticity; the grid-shaped bulges on the elastic bottom layer can well buffer the impact of the wear-resistant surface layer to the elastic bottom layer, so that the stress distribution of the elastic bottom layer is more uniform, and the service life of the coiled material is indirectly prolonged. But the bottom surface of the elastic bottom layer is still in full-area contact with the ground, the requirement on the flatness of the ground before paving is high, the heat dissipation performance of the adhesive is poor, the drying of the surface and bottom surface adhesives is not facilitated, and the construction period is further prolonged.

Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

As shown in fig. 1 to 4, a prefabricated elastic sheet of flute formula thin layer, including sheet body 1, sheet body 1 parallel surface is provided with a plurality of surface slot 11, sheet body 1 bottom surface parallel arrangement has a plurality of bottom surface slot 12, a plurality of surface slot 11 and a plurality of bottom surface slot 12 dislocation arrangement, wherein a plurality of bottom surface slot 12 form the flute structure.

By adopting the technical scheme, the surface grooves 11 and the bottom grooves 12 are arranged, so that the areas of the surface and the bottom are increased, the drying of the surface and bottom adhesives is facilitated, and the construction period is further shortened. The groove structures on the surface and the bottom surface increase the mechanical engagement between the sheet and the adhesive, and improve the bonding performance between the elastic sheet and the surface and the bottom layers. The contact area between the bottom surface and the ground is reduced through the groove structure of the bottom surface, and the requirement of the site construction on ground leveling treatment is lowered. Therefore, elasticity prefabricated sheet has better thermal diffusivity, better mechanical interlock performance, lower ground requirement of making level and material quantity still less, and then solves the problem that present elasticity surface course material exists in using better, has reduceed material cost, shortens construction cycle greatly.

The thickness of the sheet body 1 is 6 mm. The sheet body can be prefabricated into prefabricated parts with different thickness specifications so as to meet the use requirements of different paving construction occasions. The utility model discloses the thickness of making the sheet is 6mm, has satisfied the operation requirement in court betterly, reduces the actual thickness of sheet to 3mm through the flute structure simultaneously, the material quantity that has significantly reduced makes the whole elasticity of sheet better simultaneously.

The surface groove 11 is a V-shaped groove or a dovetail groove. The V-shaped groove or the dovetail groove enables the mechanical engagement performance of the later construction surface layer to be better.

The bottom groove 12 is a trapezoidal groove or a rectangular groove. The bottom surface adopts dovetail groove or rectangular channel structural design, has reduced the area of contact of sheet bottom with ground, replies with the help of the viscidity of adhesive and automatically makes level, has reduced earlier the requirement and the construction degree of difficulty of making level the processing to ground. When the bottom groove 12 is a trapezoidal groove, the formed corrugated structure is a trapezoidal corrugated structure; when the bottom surface grooves 12 are rectangular grooves, the corrugated structure formed is a rectangular corrugated structure.

The groove body depth of the surface groove 11 is 2.5mm to 3 mm.

The groove body depth of the bottom surface groove 12 is 2.5mm to 3 mm.

The sheet body 1 is integrally manufactured and molded.

The central line of the surface groove 11 is coincident with the central line of the central connecting line of two adjacent bottom grooves 12. Namely, the two adjacent bottom grooves 12 are symmetrical about the center line of the surface groove 11, so that the whole structure of the sheet is uniformly stressed and cannot be damaged due to excessive local stress.

The sheet material is formed by combining aqueous polymer emulsion, elastic particles, a thickening agent, a defoaming agent, a wetting agent and a dispersing agent. Can be flexibly paved and coated on the surface according to the requirements of application fields.
