Wall explosion-proof reinforcing module, explosion-proof wall and preparation methods of wall explosion-proof reinforcing module and explosion-proof wall

Abstract

The invention discloses a wall explosion-proof reinforcing module, an explosion-proof wall and preparation methods of the wall explosion-proof reinforcing module and the explosion-proof wall. The wallexplosion-proof enhancing module comprises a shell layer, and a foam layer, a liquid protection layer and an elastomer layer which are wrapped inside the shell layer, can absorb shock waves generatedby explosion, and is good in explosion-proof effect. For some old buildings, the structural strength of walls of the old buildings is not high, and the explosion-proof capacity is weak when the old buildings face the impact waves; and the explosion-proof module is hung so that absorption and conversion of shock wave energy can be improved, direct collision between the shock waves and wall bodiesis reduced, and therefore the corresponding protection effect is achieved, and meanwhile, the shock waves are adsorbed, so that damage of the diffracted shock waves to other parts is reduced.

Description

technical field [0001] The invention relates to the technical field of explosion-proof equipment, in particular to an explosion-proof reinforcement module for walls, an explosion-proof wall and a preparation method thereof. Background technique [0002] An explosion-proof wall is a wall that has the ability to resist shock waves and can limit the damage of an explosion within a certain range. At present, the following three types of explosion-proof walls are mainly used: [0003] The first type of explosion-proof wall is mainly designed at the beginning of building construction. Generally, the wall is reinforced by increasing the density of the internal steel mesh and using high-strength concrete. Its protection concept is to use the higher strength of the wall to "block" the shock wave so that it does not propagate behind the wall. But in fact, the shock wave will be refracted and diffracted during the propagation process, which may cause greater damage to people and obje...

AI Technical Summary

Problems solved by technology

However, this type of explosion-proof wall has a high surface density, which will increase the load-bearing capacity of the entire wall.

In addition, due to the use of high-density materials, shock waves will be transmitted and reflected between different interlayers inside the wall, which may cause greater damage to the wall itself

Moreover, this kind of wall cannot solve the problems of shock wave reflection and diffraction.

[0005] The third type of explosion-proof wall is generally a gabion net made of a certain metal and braided material frame, which is protected by filling sand in the gabion net. This form of protection is not beautiful and is not suitable for protection in ordinary buildings. At the same time, This method requires a relatively large amount of sand and soil, and the thickness of the wall is relatively large. It is suitable for the field, such as the field barracks of the army, etc.

Its disadvantage is obvious, that is, the shock wave will cause reflection and diffraction after hitting the wall itself, causing damage to other parts
