Description
Technical field
The invention belongs to deck installation structure technical field, be specifically related to a kind of polyurethane-modified polymer bridge deck pavement structure.
Background technology
At present, the scheme of paving steel bridge deck has three classes in the world: (1) bituminous mixture class: mated formation by asphalt-mastic-broken stone (SMA), cast asphalt concrete (GA) and epoxy asphalt concrete (EA); (2) cement concrete type: mated formation by high performance concrete (HPC) and polymer modification concrete (LMC); (3) mat formation by high molecular polymer class.
The loading characteristic of Steel Bridge Deck Pavement is: under the existence of (1) longitudinal stiffener and diaphragm makes load action, larger hogging moment is born in pave-load layer end face local; (2) distortion of large span steel beam bridge itself, displacement, vibration, torsion are larger; (3) circular temperature loads can produce steel box girder and have a strong impact on, and can cause the distortion of pave-load layer.
Now, domestic conventional paving steel bridge deck scheme is individual layer bituminous mixture class, but has following shortcoming: the paving thickness of (1) individual layer bituminous mixture class is between 35 ~ 80mm, and thickness is comparatively large, and the weight that steel bridge bears is large; (2) paving construction of individual layer bituminous mixture class, there are certain requirements construction environment, not easily constructs; (3) bridge floor of mating formation of individual layer bituminous mixture class is adopted easily to produce fracture, distortion; (4) bridge deck pavement structure of most of bituminous mixture class just enters after 2 ~ 3 years in use and maintains the stage frequently, and application life is shorter, maintenance difficult.
Summary of the invention
In order to solve the deficiency that existing bituminous mixture class bridge deck pavement structure exists, the invention provides a kind of polyurethane-modified polymer bridge deck pavement structure.
A kind of polyurethane-modified polymer bridge deck pavement structure, comprises Steel Bridge Deck 1, described Steel Bridge Deck 1 is equipped with intermediate layer 3 by tack coat 2, described intermediate layer 3 is equipped with wearing layer 4.
The material of described tack coat 2 is two component polyurethane modified resin special glue, and the material in intermediate layer 3 is the polymer-modified rubble of bi-component height thixotropic polyurethane, and the material of wearing layer 4 is the polymer-modified rubble of two component polyurethane.
The thickness of described tack coat 2 is 1 ~ 2mm.
The thickness in described intermediate layer 3 is 6 ~ 7mm.
The thickness of described wearing layer 4 is 2 ~ 3mm.
The material of described tack coat 2, intermediate layer 3 and wearing layer 4 is normal temperature cure.
Advantageous Effects of the present invention is:
(1) pave-load layer gross thickness of the present invention is only 9 ~ 12mm, is 1/8 ~ 1/4 of traditional pave-load layer gross thickness, alleviates the deadweight of bridge, significantly reduce engineering cost;
(2) layers of material of the present invention is polymer-modified, and modified polymer is normal temperature cure, requires low, constructability to construction environment;
(3) material of bond coating of the present invention is two component polyurethane modified resin special glue, and the caking property of itself and metal is strong, can be close to steel bridge surface;
(4) layers of material of the present invention all has good deformability, and also have that intensity is high, antifatigue, the advantage such as waterproof, corrosion-resistant.
