Construction method of anti-explosion and anti-impact composite wallboard

Abstract

The invention provides a construction method of an anti-explosion and anti-impact composite wallboard. The wallboard comprises a polypropylene fiber concrete wall formed through a pouring mode, bonding layers, fiber reinforced composite material layers, foamed aluminum filling bodies, C-shaped steel sheets, bolts and pressure relief holes. According to the method, all the components are fixed intoa whole through the C-shaped steel sheets, fragments are not prone to being generated while explosive shock waves are resisted, the secondary damage caused by the fragments is effectively avoided, and the damage to the wallboard under the explosive shock load can be effectively reduced by forming the pressure relief holes in the steel sheets; and the method can be used for wallboards of a newly-built engineering project and is also suitable for buildings with explosion-proof requirements.

Description

technical field [0001] The invention relates to the field of engineering structure protection, in particular to a method for constructing an explosion-resistant and impact-resistant composite wall panel. Background technique [0002] At present, most residential buildings, office buildings, factories and other building structures use reinforced concrete or other lightweight materials as filling walls. When various accidental explosions and terrorist explosions occur, it bears most of the load generated by the explosion shock wave, and plays a vital role in the anti-explosion of building structures. The existing concrete wall panels will be partially damaged or even collapsed under the action of explosion load, and the damage of lightweight materials under the action of explosion load is more serious; ordinary concrete structures generally resist the impact load of the explosion by increasing the strength and stiffness of the structure. This will result in high self-weight s...

AI Technical Summary

Problems solved by technology

The existing concrete wall panels will be partially damaged or even collapsed under the action of explosion load, and the damage of lightweight materials under the action of explosion load is more serious; ordinary concrete structures generally resist the impact load of the explosion by increasing the strength and stiffness of the structure. This will lead to a large self-weight stiffness of the wall structure

In addition, the concrete structure is prone to produce high-speed debris under the action of the explosion shock wave, which will cause secondary damage to personnel and property
