Assembly type concrete beam plate and installation and maintenance method

Abstract

The invention discloses an assembly type concrete beam plate and an installation and maintenance method. The assembly type concrete beam plate comprises a plurality of prefabricated bridge deck slabsand longitudinal beams; the prefabricated bridge deck slabs are arranged in a parallel mode and erected on the upper surfaces of the longitudinal beams; the prefabricated bridge deck slabs and the longitudinal beams are fixed through clamping structures; each clamping structure is formed by a rib-plate clamped in a clamping groove; each rib-plate is arranged at the end of the lower surface of thecorresponding prefabricated bridge deck slab; and each clamping groove is formed in the position, corresponding to the rib-plate, on each longitudinal beam. The prefabricated bridge deck slabs with the rib-plates are connected with the longitudinal beams with the clamping grooves, and therefore the displacement generated when the prefabricated bridge deck slabs are subjected to the dynamic load effect of vehicles is overcome; construction is convenient; and meanwhile, the service life of the bridge floor is prolonged and maintenance cost is lowered due to the fact that rigidly connected positions are segregated by flexible materials and the buffering effect is played. Hoisting holes formed in the upper surface of the prefabricated bridge deck slabs are used for convenient replacing, so that no large area damage occurs on the bridge floor structure, and time of traffic obstruction is shortened.

Description

technical field [0001] The invention relates to a bridge deck structure, a construction process and a maintenance method, in particular to an assembled concrete beam slab and an installation and maintenance method. Background technique [0002] Bridges with small and medium spans usually adopt girder bridges or arch bridges. When the bridge deck is paved, that is, the roadway pavement, it is the part where the wheels directly act. There are many forms of traffic road pavement, such as cement concrete, asphalt concrete, asphalt surface treatment and mud-bound gravel. Cement concrete and asphalt concrete bridge deck pavement are widely used and can meet various requirements. However, cement concrete pavement has low cost, good wear resistance, and is suitable for heavy-duty traffic, but the curing period is long, and it is troublesome to repair in the future; asphalt concrete pavement is light in weight, easy to maintain and open to traffic, but it is easy to age and deform. ...

AI Technical Summary

Problems solved by technology

However, cement concrete pavement has low cost, good wear resistance, and is suitable for heavy-duty traffic, but the curing period is long, and it is troublesome to repair in the future; asphalt concrete pavement is light in weight, easy to maintain and open to traffic, but it is easy to age and deform.

Asphalt surface treatment and mud-bound macadam pavement, poor durability

Regardless of whether cement concrete or asphalt concrete is used for bridge deck pavement, after it is damaged, it needs to be restricted to traffic, and the damaged area needs to be cut and chiseled, and then poured and maintained, which takes a long time and money

And the pavement of the bridge deck also needs to consume a lot of manpower and material costs
