Explosion protection system for glass curtain wall

Abstract

The invention relates to an explosion protection system for a glass curtain wall, which belongs to the field of civil structure engineering. The explosion protection system comprises a building main structure, a glass curtain wall frame column and a glass curtain wall beam, wherein the glass curtain wall frame column and the glass curtain wall beam are fixed on the building main structure. The explosion protection system is characterized in that a warp steel wire rope passes through the cavity of the glass curtain wall frame column, and a weft steel wire rope passes through the cavity of a glass curtain wall beam to form a warp-weft intersecting steel wire net; the warp steel wire rope at the edge of the steel wire rope net is tied with the broken end of the weft steel wire rope; the upper end and the lower end of the weft steel wire rope are fixed with the building main structure respectively; and an explosion protection film is attached to the curtail wall glass in a steel wire rope net covering region. Preferably, the explosion protection film is attached to the inner side of the curtain wall glass. The invention mainly aims to provide the explosion protection system for the glass curtain wall, which has reasonable stress, convenience in constructing, safety and reliability.

Description

technical field [0001] The invention relates to the field of civil and structural engineering, especially to glass curtain walls on building facades. When the glass curtain wall system faces the threat of explosion shock waves, it is an explosion-proof system for reducing casualties and property losses in buildings. Background technique [0002] Glass curtain wall facade design is more and more widely used in buildings, especially in the facade design of public buildings. The existing glass curtain wall is mainly designed to bear wind load and vertical load, and it is basically undefended in the face of blast shock waves. A series of examples of terrorist activities at home and abroad show that bombing attacks on large public buildings (such as theaters, transportation hubs, etc.) will often greatly damage the glass curtain wall support system of the building's facade, and may even cause continuous collapse of the support system. Effect; the explosion shock wave engulfs the...

The existing glass curtain wall design mainly considers bearing wind load and vertical load, and it is basically undefended in the face of blast shock waves

A series of examples of terrorist activities at home and abroad show that bombing attacks on large public buildings (such as theaters, transportation hubs, etc.) will often greatly damage the glass curtain wall support system of the building's facade, and may even cause continuous collapse of the support system. effect; the explosion shock wave engulfs the high-speed curtain wall glass fragments and splashes around, which will cause more serious secondary damage to the dense crowd
