Abstract

The invention discloses a fatigue-resistant multi-layer bending-resistant anti-seismic steel bearing plate, and relates to the technical field of steel bearing plates. The fatigue resistance, bending resistance and earthquake resistance are improved; the steel bearing plate specifically comprises a plurality of steel bearing plate modules, each steel bearing plate module comprises a first plate body, a second plate body and a third plate body, the first plate bodies, the second plate bodies and the third plate bodies are provided with protruding parts and sunken parts at equal intervals, the protruding parts and the sunken parts are distributed in a staggered mode, the sunken parts of the first plate bodies correspond to the protruding parts of the second plate bodies, and the sunken parts of the second plate bodies correspond to the protruding parts of the third plate bodies. And the concave part of the second plate body corresponds to the convex part of the third plate body. According to the steel bearing plate module, the first plate body, the second plate body and the third plate body are arranged, the concave parts and the convex parts are of matched isosceles trapezoid structures, when the steel bearing plate module is formed, the concave parts and the convex parts can form a hexagonal structure, and therefore the structural firmness is guaranteed; reliable support is provided between the convex part and the concave part, and good fatigue resistance, bending resistance and earthquake resistance are achieved.

Description

technical field [0001] The invention relates to the technical field of steel bearing plates, in particular to a fatigue-resistant multi-layer bending-resistant and seismic-resistant steel bearing plate. Background technique [0002] Steel bearing plate is a kind of building material with reinforcement, which can meet the requirements of rapid construction of the main steel structure, can provide a firm working platform in a short time, and can use multiple floors to lay profiled steel plates and pour concrete slabs in layers. Although the current steel deck can meet certain requirements, its structure has poor fatigue resistance, bending and seismic performance, and is prone to bending deformation, so it needs to be improved. [0003] After retrieval, the Chinese patent application number CN201810568165.7 discloses a steel bearing plate, which includes a bottom plate and two side plates, the two side plates and the bottom plate enclose a pouring groove for pouring concrete, ...
