The construction method of above-mentioned orthotropic steel bridge deck paving structure, following steps:
1) prefabricated rubber layer 4, aluminium alloys surface layer 5, shearing resistance weldering follow closely 2 in advance; On rubber layer 4, be reserved with hole;
2) on steel bridge deck 1, follow closely 2 according to equidistant welding shearing resistance weldering;
3) welded after shearing resistance weldering nail 2, on steel bridge deck 1, smeared epoxy resin gluing layer 3;
4) prefabricated rubber layer 4 is mated formation on epoxy resin gluing layer 3, and shearing resistance weldering nail 2 is inserted in the hole of rubber layer 4 accordingly;
5) smear epoxy resin gluing layer 3 at rubber layer upper surface;
6) on the rubber layer that scribbles epoxy resin gluing layer, lay aluminium alloys surface layer.
The utility model, with respect to prior art, has following advantage and effect:
The rubber layer production that is prefabricated in the factory, plays waterproof, heat insulation, buffering load, provides the effects such as operation platform, and its soffit is reserved with the equally spaced hole corresponding with shearing resistance weldering nail on steel bridge deck (orthotropic), for assigning shearing resistance weldering nail; Rubber layer upper surface is reserved with the equally spaced hole corresponding with the protruding nail of shearing resistance of prefabricated aluminium alloys surface layer soffit, and the splicing of being convenient to is at the construction field (site) installed.
Rubber layer has good load-bearing and transmits the performance of load, and to bridge construction, distortion has good following.
Epoxy resin gluing layer has good adhesive property, spreads upon on the steel bridge deck that has welded shearing resistance weldering nail, and rubber layer and steel bridge deck are bonded together, and can also prevent steel plate corrosion; Spread upon on rubber layer, aluminium alloys surface layer and rubber layer are bonded together, can also play the effect of waterproof isolation.
The production that is prefabricated in the factory of aluminium alloys surface layer, groove or the horizontal steel bar of antiskid are set at upper surface, be conducive to increase the frictional force between doughnut, long-term antiskid function is provided, ensure traffic safety, be provided with the protruding nail of equally spaced shearing resistance at aluminium alloys surface layer soffit, improve and the shearing resistance adhesion of lower floor, avoid producing and move horizontally, push away and the disease such as gather around.
