Embodiment Construction

[0020] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0021] see figure 1 , a steel bridge deck pavement structure, comprising a steel bridge deck 1, an elastic crack-resistant layer 3 is laid on the steel bridge deck 1 through a bonding layer 2, and a wear layer 4 is arranged on the elastic crack-resistant layer 3.

[0022] The material of the bonding layer 2 is a two-component polyurethane modified resin special adhesive, and the thickness of the bonding layer 2 is 1-1.5mm; the material of the elastic anti-cracking layer 3 is a two-component high thixotropic pure elastic polyurethane modified The thickness of the elastic anti-cracking layer 3 is 6-7 mm; the material of the wearing layer 4 is two-component polyurethane modified polymer gravel, and the thickness of the wearing layer 4 is 3-5 mm.

[0023] The materials of the adhesive layer 2, the elastic anti-crack layer 3 and the wear layer 4 are...

Abstract

A steel bridge deck laying structure comprises a bonding layer, an elastic anti-cracking layer and an abrasion layer. The elastic anti-cracking layer is laid on the upper surface of the bonding layer, and the abrasion layer is tightly attached to the upper surface of the elastic anti-cracking layer. The bonding layer is made from bi-component polyurethane modified special resin glue, the elastic anti-cracking layer is made from bi-component high-thixotropic purely elastic polyurethane modified polymer gravels, and the abrasion layer is made from bi-component polyurethane modified polymer gravels.

Description

technical field [0001] The invention belongs to the technical field of bridge deck pavement structures, in particular to a steel bridge deck pavement structure. Background technique [0002] At present, there are three types of steel bridge deck pavement schemes in the world: (1) Asphalt mixture: Pavement made of asphalt mastic macadam (SMA), cast asphalt concrete (GA) and epoxy asphalt concrete (EA) ; (2) Cement concrete: paved by high performance concrete (HPC) and polymer modified concrete (LMC); (3) Paved with high molecular polymers. [0003] The mechanical characteristics of the steel bridge deck pavement are: (1) the presence of longitudinal stiffeners and diaphragms makes the top of the pavement under the load to locally bear a relatively large negative bending moment; (2) the long-span steel box girder The deformation, displacement, vibration, and torsion of the bridge itself are large; (3) Seasonal temperature changes will have a serious impact on the steel box gi...
