Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof walls, in particular to a lightweight explosion-proof wall structure. Background Art

[0002] Explosion is a rapid chemical or physical change process of matter, during which huge amounts of heat are quickly released and a large amount of gas is generated. At this time, the gas has great pressure because it still exists in a limited space for a moment, and it exerts strong pressure on objects around the explosion point. When the high-pressure gas expands rapidly, an explosion is formed, and an explosion-proof wall needs to be installed on the wall. The explosion-proof wall is a device that can instantly release the critical pressure to provide a closed explosion pressure for indoor combustion and explosion.

[0003] The current explosion-proof walls are too heavy during the installation process, which increases the load on the main structure, makes the installation difficult, time-consuming and costly, and results in low work efficiency. The explosion-proof panel materials disperse when an explosion occurs, and cannot effectively reduce the superposition effect of the explosive force, thereby causing injuries and losses to personnel. The safety is not high. When the construction enters the final process, wet operations are easily caused due to the long construction time, thereby reducing the explosion-proof effect of the explosion-proof wall and the construction quality. Therefore, technical personnel in this field provide a lightweight explosion-proof wall structure to solve the problems raised in the above-mentioned background technology. Summary of the invention

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a lightweight explosion-proof wall structure is proposed. The explosion-proof wall is installed by using a single-layer explosion-proof board and a double-layer explosion-proof board as a fiber-reinforced silicate board to make it lighter, more effectively reduce the load of the main structure, and reduce the cost. Then, the fiber-reinforced silicate board is a lightweight and brittle material, which can be dissipated in a very short time when encountering an explosion, effectively reducing the superposition effect of the explosive force, providing protection for personal and property safety, thereby improving safety. Then, it is fixed by self-tapping screws, expansion bolts and self-drilling screws, so that the system installation is simple and quick, thereby improving construction efficiency and reducing construction period. Finally, after the explosion-proof wall is quickly installed, the surface is very flat. No leveling layer is required during the construction of the exterior wall paint, and the final process can be completed directly, which is beneficial to improving the wall construction efficiency and construction quality.
