SCS (steel concrete steel) bridge deck with internal vertical J-shaped connecting structures

Abstract

The invention discloses an SCS (steel concrete steel) bridge deck with internal vertical J-shaped connecting structures. The SCS bridge deck comprises a bottom plate, a top plate, N rows of vertical J-shaped connecting structures, and an inter-plate concrete structure made of concrete poured between the top plate and the bottom plate. The vertical J-shaped connecting structures are all cast in the inter-plate concrete structure. The top plate and the bottom plate are integrally connected with the N rows of vertical J-shaped connecting structures through the inter-plate concrete structure. Each row of vertical J-shaped connecting structures comprises a plurality of vertical J-shaped connecting structures distributed from front to rear; each vertical J-shaped connecting structure comprises an upper connector fixed to the bottom of the top plate and a lower connector hooked to the upper connector; the upper connector and the lower connector are both J-shaped hooks. The SCS bridge deck is simple in structure, reasonable in design, convenient to construct, effective to use and good in mechanical property, and the problems in the existing concrete deck can be solved.

Description

technical field [0001] The invention relates to a bridge deck, in particular to an SCS steel plate concrete bridge deck with a built-in vertical J-shaped connection structure. Background technique [0002] Steel plate sandwich concrete (steel-concrete-steel, referred to as SCS) composite structure, also known as SCS steel plate concrete structure, is a steel-concrete composite structure formed by two steel plates and concrete poured in the interlayer between the two steel plates. Because steel and concrete make up for each other's weaknesses and give full play to each other's strengths, the SCS steel plate concrete structure has high bearing capacity and excellent mechanical properties. Therefore, SCS steel plate concrete structures will be more and more widely used in structures such as offshore platforms and long-span, heavy-duty, and light bridges. [0003] At present, most of the bridge decks used are concrete bridge decks. In the actual use process, the concrete bridg...

AI Technical Summary

Problems solved by technology

In the actual use process, the concrete bridge deck has the following defects: first, the self-heavy weight limits the structure and size of the lower supporting pier; Steel structure load-bearing girders such as steel box girders) are connected, but the connection performance between the steel structure and the concrete is poor, so a large number of shear connectors are needed, and the amount of steel is large; third, due to the perennial dynamic load, the bridge deck The top and bottom of the concrete bridge deck are most affected, and the bottom of the concrete bridge deck is prone to cracks, which eventually lead to the failure of the concrete bridge deck

Due to the above reasons, the development and application of concrete bridge decks are limited.
