Corrugated steel explosion-proof wall structure

Abstract

The invention relates to a corrugated steel explosion-proof wall structure, and belongs to the technical field of disaster prevention and reduction engineering. The structure is characterized in thata closed rectangular ring structure is made of a plurality of wrapping steel plates, a transverse steel plate covering the whole annular face is fixed to one side of the wrapping steel plates, a firstgalvanized corrugated steel plate assembly covering the whole annular face is fixed to the other side of the wrapping steel plates, a second galvanized corrugated steel plate assembly is arranged between the first galvanized corrugated steel plate assembly and the transverse steel plate, fiber concrete is poured between the first galvanized corrugated steel plate assembly and the second galvanized corrugated steel plate assembly, and high-strength concrete is poured between the second galvanized corrugated steel plate assembly and the transverse steel plate. According to the structure, the explosion-proof capacity is high, the deformation of the corrugated steel plate is utilized to dissipate explosion energy, the energy dissipation effect is good, and the mechanical property is good.

Description

technical field [0001] The invention relates to a corrugated steel explosion-proof wall structure, which belongs to the technical field of disaster prevention and mitigation engineering. Background technique [0002] Some special structures, such as chemical plants and gas stations, often cause a large number of casualties and economic property losses due to explosions. Such special structures need to be equipped with separate explosion-proof walls to reduce casualties. Optimizing the structure and system of the explosion-proof wall becomes the most effective anti-blast design approach. Due to the limited indoor space in explosive places such as chemical plants, once an explosion accident is caused by improper storage of flammable and explosive chemicals, the consequences will be disastrous. The damage mode of the wall under the action of near blast needs to be considered separately, and it is necessary to design a blast-proof wall structure with good energy dissipation in t...

Problems solved by technology

[0003] The Chinese patent with the authorized announcement number CN105952013B proposes a large deformation anti-bending explosion-proof wall, multi-layer light corrugated steel plates are arranged at equal intervals, and the failure mode of the wall under the near-explosion condition is not considered, that is, the center area is severely damaged

Under this condition, the explosion-proof wall structure has the same protection effect at all positions of the explosion-proof wall because the corrugated steel spacing of each section is the same. It is very uneconomical, and at the same time, the damage mode of the near explosion on the wall is not fully considered. There is no key protection in the center of the wall, so the anti-blast effect and efficiency of this structure are not high;

[0004] The Chinese patent with the publication number CN1687543A proposes a multi-layer composite structure explosion-proof wall. The explosion-proof wall body of this structure is provided with a concrete layer on the explosion-facing surface and the back explosion surface. Because the concrete tensile capacity is weak, the concrete on the back explosion surface And the rear position of the concrete layer on the explosion-facing surface is very prone to cracking under the action of the explosion shock wave, which in turn affects the overall anti-blast performance of the explosion-proof wall structure.
