Assembled integral type reinforced concrete slab bridge structure and construction method thereof

Abstract

The invention discloses an assembled integral type reinforced concrete slab bridge structure and a construction method thereof.The assembled integral type reinforced concrete slab bridge structure comprises a concrete plate layer, a reinforcing steel bar cage is fixedly embedded in the concrete plate layer and comprises longitudinal steel bars and transverse connecting rings, the surfaces of the longitudinal steel bars are bent to form bent parts, and the transverse connecting rings are connected with the longitudinal steel bars; combined connecting parts are formed on the surfaces of the two sides of the bent part respectively, the surfaces of the transverse connecting rings are fixedly connected to the surfaces of one sides of the combined connecting parts, reinforcing connecting steel bars are fixedly connected to the surfaces of one sides of the transverse connecting rings, and a connecting cylinder is fixedly embedded in the surface of one side of the concrete plate layer. The structural strength is guaranteed by embedding the reinforcing steel bar cage into the concrete plate layer, meanwhile, the longitudinal steel bars are bent to form different bent parts and combined connecting parts, and the connecting cylinders are embedded into the surfaces, so that hoisting and transferring are facilitated after forming, the use convenience and stability can be greatly improved, the safety and high efficiency of construction are guaranteed, and the construction cost is reduced. The popularization is convenient.

Description

technical field [0001] The invention relates to the field of concrete slab bridges, in particular to an assembled integral reinforced concrete slab bridge structure and a construction method thereof. Background technique [0002] In the current social life and development, more and more highways are being built, and the scale of bridges across rivers and roads is also increasing. In order to ensure the construction period, it is generally necessary to use integrally assembled slab bridge structures. Can be combined and spliced ​​directly. [0003] However, in the existing concrete slab bridge structures, most of them are reinforced by built-in steel bars in a single direction, and then directly poured into the shape. In this way, not only the rigidity of the steel skeleton is weak, it is not conducive to the stable combination with the concrete, the safety factor is insufficient, and the pouring construction is affected. Forming efficiency, and after the slab bridge is form...

Problems solved by technology

[0003] However, in the existing concrete slab bridge structures, most of them are reinforced by built-in steel bars in a single direction, and then directly cast into shape. Forming efficiency, and after the slab bridge is formed, it is not conducive to lifting for transfer and installation, which affects the reduction of subsequent construction. A new structural form needs to be proposed
