Anti-explosion wall end shear seam composite profile

Abstract

The invention provides an anti-explosion wall end shear seam composite profile which comprises a first shell and a second shell which are of the same structure, a multifunctional cavity is defined by the first shell and the second shell, transverse partitions are arranged on the two opposite sides of the first shell and the second shell, and from the position close to the interior of a room to the position away from the interior of the room, the multifunctional cavity is divided into a fireproof flame-retardant unit, a heat insulation unit and a waterproof and moistureproof unit; and an embedded fixing key is arranged on the side, opposite to the anti-explosion wall, of the first shell, and an embedded fixing key is arranged on the side, opposite to a structural column, of the second shell. According to the shear seam composite profile with the embedded fixing keys, it is guaranteed that when explosion occurs, the anti-explosion wall and the structural column can be completely disengaged, and shear force is not transmitted. Meanwhile, through the combination of the fireproof flame-retardant unit, the heat insulation unit and the waterproof and moistureproof unit in the multifunctional chamber, the conventional building functions such as moistureproof, heat insulation and fireproof functions are well achieved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a composite section material for a shear joint at the end of an anti-blast wall. Background technique [0002] Anti-blast structures with anti-blast walls are widely used in petrochemical, military and other fields, such as cabinet rooms, central control rooms, etc. As a special structural component bearing blast loads, the blast-resistant wall has a special layout compared with conventional buildings. [0003] In the past, it was mainly used to arrange the entire explosion-resistant wall around the building, separate from the concrete column of the main structure, connect the upper end to the roof panel, and connect the lower end to the rigid floor and foundation, leaving the blast-resistant wall and structural column The gap between them prevents the middle part of the anti-blast wall from colliding with the structural column due to out-of-plane bending deformation afte...

AI Technical Summary

Problems solved by technology

This method solves the problem of cracks in the wall, but there are steel bars between the wall columns. When the blast-resistant wall bears the blast load, the side of the wall will have a horizontal effect on the structural columns, and even pull the tie bars, which is harmful to the concrete columns. cause structural damage
