Abstract
The utility model relates to a thin-layer modified polyurethane steel bridge deck pavement structure. The bridge deck pavement consists of a corrosion-resistant layer, a water-proof bonding layer, a polymer anti-cracking functional layer, an upper bonding layer and a polymer anti-slip-wear layer, wherein the water-proof bonding layer and the upper bonding layer are modified polyurethane material layers; the polymer anti-cracking functional layer is a modified polyurethane prefabricated block splicing layer, that is, the polymer anti-cracking functional layer is spliced by using modified polyurethane prefabricated blocks; the polymer anti-slip-wear layer is a mixed material layer consisting of a modified polyurethane bonding material and gravels. The applied modified polyurethane is light, water-impermeable, wear-resistant and corrosion-resistant, and has the advantages of excellent elastic restoration rate and superior steel plate deformation following capability. The modified polyurethane prefabricated block splicing layer is convenient for construction, and is easy to repair.
Description
Technical field
The utility model belongs to deck installation structure technical field, is specifically related to a kind of bridge deck pavement structure.
Background technology
Paving steel bridge deck has 3 large classes in the world at present: (1) bituminous mixture class, has asphalt-mastic-broken stone SMA, cast asphalt concrete GA and epoxy asphalt concrete EA; (2) coagulating cement great soil group, has high performance concrete (HPC), polymer modification concrete (LMC); (3) high molecular polymer class.Domestic conventional paving steel bridge deck is bituminous mixture class, and thickness is between 35～80mm.From the destruction statistical conditions of paving steel bridge deck in recent years, because larger hogging moment is born in the effect of longitudinal stiffener and the diaphragm layer end face part that make to mat formation, the distinctive mechanical characteristic of asphalt mixture material and environmental sensitivity cannot fundamentally be resolved paving steel bridge deck disease.
Summary of the invention
The deficiency existing in order to solve bituminous concrete class class bridge deck pavement structure, the thin layer modified polyurethane bridge deck pavement structure that the utility model provides that a kind of quality is light, high strength, good pliability, good steel plate chase after sex change, endurance and durability.
A kind of thin layer modified polyurethane bridge deck pavement structure is made up of anticorrosive coat, water-proof tack coat, polymers anti-cracking functional layer, upper strata tack coat and polymer antiskid wearing layer, and wherein anticorrosive coat is laid immediately on Steel Bridge Deck; Described water-proof tack coat and upper strata tack coat are modified polyurethane material layer, and described anticorrosive coat is epoxy zinc-rich paint material layer or inorganic zinc rich paint material layer; Described polymers anti-cracking functional layer is modified polyurethane prefabricated section splicing layer, is made up of the splicing of modified polyurethane prefabricated section; Described polymer antiskid wearing layer is the mixed material layer of modified polyurethane cementitious materials and rubble.
The thickness of described anticorrosive coat is 0.08mm.
The thickness of described water-proof tack coat is 0.5～1.5mm.
Described modified polyurethane prefabricated section is rectangular block, and length is 500mm, and width is 300mm, and thickness is 5～10mm.
The thickness of described upper strata tack coat is 0.2～0.5mm.
The thickness of described polymer antiskid wearing layer is 3～10mm.
Useful technique effect of the present utility model is: in water-proof tack coat, upper strata tack coat and polymer antiskid wearing layer, used respectively modified polyurethane material; Modified polyurethane is thermoset material, and its quality is light, waterproof, abrasion resisting, corrosion-resistant, and strong with the caking property of metal, compressive strength and tensile strength are high, have again the advantages such as good elastic restoration ratio and the good ability of following steel plate deformed simultaneously.The modified polyurethane prefabricated section making polymers anti-cracking functional layer that polymers anti-cracking functional layer adopts batch production to produce, performance is excellent, and temperature sensitivity is low, steady quality, easy construction, easy-maintaining.
The utility model solves the chronic disease that the outer paving steel bridge deck of Now Domestic exists, and the lifting of domestic even international steel deck paving packing technique and level is had great importance.
