Problems solved by technology

As mentioned above, the pavement layer of the steel bridge deck pavement structure has the following disadvantages: 1. There is a problem that the steel bridge deck is not easy to be paved during the pavement process; 2. The pavement body is easily deformed and easily deformed during use. The problem of shedding, especially after several years of use, the pavement body will also appear cracked or even sunken in some areas; 3. The durability and bending resistance of the pavement body are poor

Embodiment 1

[0017] A steel bridge deck pavement, such as figure 1 As shown, it includes a prefabricated module layer and an anti-slip layer arranged on the surface of the prefabricated module layer, the prefabricated module layer is fixed on the surface of the elastic transition layer, the elastic transition layer has self-leveling performance and its elastic recovery rate is not less than 98%. Among them, the elastic transition layer is made of epoxy modified polyurethane and fillers with a particle size of less than 5mm (light calcium carbonate: hollow microbeads: fumed silica = 70:25:15, the ratio is the mass ratio) Therefore, the ratio of powder to glue in the epoxy modified polyurethane is powder: glue = 75:30, the thickness of the obtained elastic transition layer is 10mm, the compression ratio of the elastic transition layer is not more than 4%, and the elastic recovery rate is more than 99 %; The prefabricated module layer is a hollow profile layer prefabricated with polyarylene s...

Embodiment 2

[0020] A steel bridge deck pavement, such as figure 2 As shown, it includes a prefabricated module layer and an anti-slip layer arranged on the surface of the prefabricated module layer, the prefabricated module layer is fixed on the surface of the elastic transition layer, the elastic transition layer has self-leveling performance and its elastic recovery rate is not less than 98%. The elastic transition layer is prepared by blending epoxy-modified polyurethane and fillers with a particle size of less than 5 mm (kaolin: hollow microbeads: fumed silica = 65:30:10). The ratio of powder to glue is powder: glue = 70:30, the thickness of the obtained elastic transition layer is 15mm, the compression ratio of the elastic transition layer is not more than 4%, and the elastic recovery rate is more than 99%; the prefabricated module layer is made of modified ASA (graft copolymer of acrylic rubber body and acrylonitrile, styrene) prefabricated hollow profile layer with a thickness of ...

Embodiment 3

[0022] A steel bridge deck pavement layer, which includes a prefabricated module layer and an anti-slip layer arranged on the surface of the prefabricated module layer, the prefabricated module layer is fixed on the surface of an elastic transition layer, and the elastic transition layer has self-leveling performance and elastic recovery. The rate is not less than 95%. Among them, the elastic transition layer is prepared by blending epoxy-modified polyurethane and fillers with a particle size of less than 5 mm (light clay: hollow microbeads: fumed silica = 60:10:5), and epoxy-modified polyurethane The ratio of powder to glue is powder: glue = 75:25, the thickness of the obtained elastic transition layer is 12mm, the compression ratio of the elastic transition layer is not more than 4%, and the elastic recovery rate is more than 99%; the prefabricated module layer is made of ASA, PA, PVC alloy prefabricated profile layer with a thickness of 30mm; anti-slip layer is a blend of p...

Abstract

The invention provides a steel bridge deck pavement, comprising a prefabricated module layer and an anti-skid layer arranged on the surface of the prefabricated module layer, characterized in that: the prefabricated module layer is bonded to the surface of an elastic transition layer, and the elastic transition layer has Self-leveling performance and its elastic recovery rate is not less than 95%. The steel bridge deck pavement layer provided by the invention is thin and light, and can greatly reduce the dead load of the steel bridge deck pavement; the steel bridge deck pavement layer provided by the invention can not only solve the problem that the steel bridge deck is not easy to pave, Moreover, it can prevent the deformation and falling off of the steel deck pavement layer during use, and can also prevent local fragmentation and depression of the steel bridge deck pavement body; the durability and flexural resistance of the steel bridge deck pavement body of the present invention Very good.

Description

technical field [0001] The invention belongs to the technical field of steel bridge deck paving, in particular to a steel bridge deck pavement layer. Background technique [0002] In the prior art: Document CN210002255U provides a thin steel bridge deck pavement structure suitable for laying on the girder deck of a slow-traffic system bridge, which includes a concrete base and a waterproof layer laid on the girder deck in turn. and a paving layer, the paving layer includes a primer, a gravel layer and an antifouling layer, the primer is laid on the surface of the waterproof layer, and the gravel layer is laid on the surface of the primer, so The antifouling layer is laid on the surface of the gravel layer; document CN209584828U discloses a steel bridge deck pavement layer, comprising: an adhesive layer arranged on the surface of the steel bridge deck; and an upper surface of the adhesive layer The composite material layer, the composite material layer is a polyvinyl alcohol...
