Problems solved by technology

[0002] There are more and more accidents that the bridge slabs of viaducts are broken or partly torn away from the main body of the bridge. The main reason is that the current bridge slabs are mainly poured with reinforced concrete, and the bonding force of the concrete is insufficient and the tension of the steel skeleton is not enough. prone to such accidents

Embodiment Construction

[0016] Do further description below in conjunction with accompanying drawing:

[0017] like figure 1 As shown, the bridge slab of the present invention is composed of several main girders poured and fixed, steel cables 3 are wound around the whole exterior of several main girders 1, and there is a certain gap between the several main girders 1 when they are placed on the beams. A steel cable connector 2 is arranged in the gap, such as figure 2 , the cable connector includes two connecting rods 5 provided with reverse threads, the connecting rods 5 are fixed by the thread and the joint block 6, when the steel cable 3 is wound, the steel cables 3 respectively pass through the steel cables arranged on the connecting rod 5 Through the through hole, after the steel cable 3 is wound, by rotating the joint block 6, the connecting rod 5 shrinks, thereby tensioning the steel cable 3, and the head of the steel cable passes through the steel cable connector 2, and the connecting rod 5 ...

Abstract

The invention discloses a bridge plate which comprises a plurality of girders and a tensioning mechanism. The plurality of the girders in array are transversely disposed on a cross beam between bridge piers to form a bridge body and fixed through the tensioning mechanism. Compared with a conventional beam and slab structure in a pure reinforced concrete structure, since steel cables are superior to rebars in toughness and tensile strength, the bridge plate in the structure can bear higher shearing force brought by bridge load bearing, possibility of cross fracture of the bridge plate is greatly reduced, and bridge bearing capacity is improved.

Description

technical field [0001] The invention relates to a bridge plate, which belongs to the field of construction. Background technique [0002] There are more and more accidents that the bridge slabs of viaducts are broken or partly torn away from the main body of the bridge. The main reason is that the current bridge slabs are mainly poured with reinforced concrete, and the bonding force of the concrete is insufficient and the tension of the steel skeleton is not enough. It is easy to cause such accidents. Contents of the invention [0003] The purpose of the present invention is to provide a bridge slab structure with better integrity and more stability. [0004] The present invention is achieved in the following manner: [0005] A bridge slab, the bridge slab includes several main beams and a tensioning mechanism, the arrays of the several main beams are placed horizontally on the crossbeams between the piers to form the main body of the bridge, and the tensioning mechanism...
