Deformation adaptation type anti-impact wall

Abstract

The invention provides a deformation adaptation type anti-impact wall. The deformation adaptation type anti-impact wall comprises a negative stiffness plate, a deformation adaptation interlayer and aback plate, wherein the deformation adaptation interlayer is arranged between the negative stiffness plate and the back plate; the deformation adaptation interlayer comprises a first rigidity layer and a second rigidity layer; the rigidity of the first rigidity layer is smaller than that of the second rigidity layer; the outer side of the first rigidity layer is connected with the negative rigidity plate; the outer side of the second rigidity layer is connected with the back plate; the inner side of the first rigidity layer is connected with the inner side of the second rigidity layer; a connecting surface of the first rigidity layer and the second rigidity layer is in a preset arc shape; the back plate comprises two or more layers of steel plates; and a plurality of spaces are arranged between every two layers of steel plates. By means of the anti-impact wall, the anti-explosion and anti-impact performance of the wall can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of explosion-proof and shock-proof, in particular to a deformation-adaptive shock-resistant wall. Background technique [0002] Explosives have largely come to dominate modern warfare since thermal weapons were introduced into the military. Therefore, it is necessary to do special anti-blast design for some specific important buildings to enhance the safety of the buildings. [0003] However, the main idea of ​​the anti-blast design in the current prior art is to fully bear the impact of the explosion through concrete or steel plates. However, in order to fully resist the destructive force of the explosion, the wall thickness of this rigid wall is generally very thick, and the anti-explosion effect is not significant. In addition, due to the excessive weight of the wall, it is easy to form a weak surface at the joint. After the explosion, the wall is prone to collapse and cause secondary damage. ...
