Filling wall explosion venting structure of multi-layer frame structural public building

Abstract

The invention discloses a filling wall explosion venting structure of a multi-layer frame structural public building, and belongs to the technical field of public building explosion venting. The explosion venting structure comprises a frame structure main body and a filling wall; the filling wall comprises a building block filling wall body and an explosion venting wall body, the building block filling wall body is connected with the frame structure main body and the explosion venting wall body through misalignment building of building blocks, and the surface of the building block filling wallbody is provided with a polymer material reinforcing layer; and the explosion venting wall body comprises a section steel frame and a foam concrete composite plate, the foam concrete composite plateis arranged in the section steel frame, and the section steel frame and the frame structure main body are connected through pre-embedded pieces. As for the polymer material reinforcing layer in the explosion venting structure, debris splash after part of a wall body built by the building blocks is destroyed during explosion is prevented, the foam concrete composite plate and the frame structure main body are connected by adopting the pre-embedded pieces, the composite wall body is smashed first during explosion, the explosion venting function is achieved, but the section steel frame of a wallplate and the main body are not separated.

Description

technical field [0001] The invention relates to the technical field of explosion venting of public buildings, in particular to an explosion venting structure of a filling wall of a public building with a multi-layer frame structure. Background technique [0002] In our cities, there are many multi-storey frame structure public buildings with dense traffic, such as school teaching buildings, hospitals, shopping malls, stations, hotels, city halls, etc. At present, in the structural design of these public buildings, the destructive effect of the blast load on the structure is generally not considered. However, in recent years, suicide bomb terrorist attacks have occurred frequently around the world, and explosions caused by other reasons such as gas and chemicals have also frequently appeared in the news. Once an explosion occurs inside this type of building, it will not only directly cause casualties and damage to people and property near the explosion source, but also cause...
