Abstract

The invention relates to a light modular explosion-proof wall, which includes a plurality of structural units arranged side by side, and the structural units are connected by high-strength bolts; the structural unit includes a protective panel, a pressure plate and a panel with adjustable protection angle Bracket, the panel bracket includes a bottom frame, a side frame, a main support, an auxiliary support and an electric push rod, the upper end of the auxiliary support is provided with a horizontal bracket for placing the side frame, and the middle part of the side frame is hinged on the horizontal bracket On one side of the side frame, a plurality of cells for installing protective panels are evenly distributed on the side frame, and each cell is provided with a protective panel. The present invention adopts modular design, simple structure, rapid and flexible construction, extensible expansion, automatic auxiliary function, good comprehensive protection performance, adjustable protection level, light structure weight under the same protection area and the same explosion load protection requirements, and The advantages of rapid repair and reuse after the structure is damaged.

Description

technical field [0001] The invention relates to safety protection technology, especially the safety protection technology for shock waves and fragments generated by explosions in the event of accidental explosions or terrorist explosion attacks, in particular to a light modular explosion-proof wall. Background technique [0002] Terrorist bombing attacks at home and abroad mainly include car bombs, fixed luggage bombs, self-igniting personal bombs and mail (package) bombs. In addition, accidental explosion safety accidents in places such as petroleum, chemical, and flammable and explosive storage warehouses will also cause major economic losses and social impacts. The explosion-proof wall has the ability to resist blast shock waves and has certain restrictions on the destructive effect of fragments. It is an effective safety protection measure for accidental explosions or terrorist explosions. [0003] At present, traditional explosion-proof walls mainly include the followi...

AI Technical Summary

Problems solved by technology

[0003] At present, traditional explosion-proof walls mainly include the following three forms: the first type is geotechnical explosion-proof wall, which is constructed by filling the space with sand, soil, stone and other convenient materials in the geosynthetic space, and uses the quality of sand and stone to resist the explosion , which is convenient to obtain materials, but the workload is large, and the overall resistance is not high; the second type is water explosion-proof wall, which uses the weight and inertia of water to resist the explosion, which is convenient to obtain materials, but the main problem is that the resistance is not high; the third type It is a reinforced concrete explosion-proof wall. This type of explosion-proof wall is a fixed anti-explosion structure with high strength and rigidity. The resistance level is higher than that of geotechnical explosion-proof walls and water body explosion-proof walls. and prone to secondary fragmentation

In addition, there are some other forms of explosion-proof walls, such as folding or fabricated explosion-proof walls. In the prior art, after such explosion-proof walls are assembled by plastic or steel plate members, sand and other materials need to be filled inside, and the construction is still relatively cumbersome.

[0004] To prevent accidental explosions or terrorist explosions, not only requires the construction time of the explosion-proof wall to be short, but also requires that the explosion-proof wall should have an anti-blast capability equivalent to the estimated explosion equivalent. Under the same protection requirements, the above-mentioned explosion-proof wall is flexible in structure weight and construction method. There are still some deficiencies in safety, construction efficiency, comprehensive protection against blast shock waves and fragments, on-demand adjustment of protection capabilities, and rapid repair after structural damage for reuse.
