A prefabricated anti-blast wall and its construction method

Abstract

The invention relates to a fabricated anti-explosion and explosion reduction wall and a construction method thereof. The fabricated anti-explosion and explosion reduction wall comprises general steelplates, polyurethane foam aluminum and steel fiber concrete fabricated wall bodies and studs; the general steel plates, the polyurethane foam aluminum and the steel fiber concrete fabricated wall bodies form a double sandwich structure wall body from the outside to the inside; the studs are vertically and alternately welded on the inner sides of the general steel plates on both sides, the top endsof the studs penetrate through the polyurethane foam aluminum and are inserted into the inner portion of the steel fiber concrete fabricated wall bodies to serve as connecting pieces to connect the steel fiber concrete fabricated wall bodies with the steel plates of the surface layer, and the connection strength between concrete and the general steel plates is strengthened; and the end of the fabricated anti-explosion and explosion reduction wall is arranged as a tooth shape, and splicing different fabricated anti-explosion and explosion reduction walls is convenient. The fabricated anti-explosion and explosion reduction wall greatly improves the anti-explosion performance of the fabricated wall body, and at the same time, the steel plates on the concrete surface can effectively avoid thesecondary damage to personnel and equipment caused by the ejection of concrete fragments.

Description

technical field [0001] The invention relates to an anti-blast wall, in particular to an assembled anti-blast reducing wall and a construction method thereof, belonging to the technical field of building structures. Background technique [0002] At present, reinforced concrete walls are often used as load-bearing walls in civil high-rises, residential buildings, office buildings, etc., but the existing reinforced concrete walls have insufficient blast resistance or unreasonable designs, and terrorist explosions and accidental explosions occur The shock wave will cause serious damage to the reinforced concrete wall, causing the wall to collapse and debris to fly, causing casualties and equipment damage. In order to effectively prevent or reduce the damage of reinforced concrete walls, we need a new type of prefabricated anti-blast and attenuation wall to prevent the wall from collapsing and reduce the number of debris flying on the wall. Contents of the invention [0003] I...
