Explosionproof energy-consumption lightweight steel construction column

Abstract

The invention aims at overcoming the defects existing in the prior art and aims at providing an explosionproof energy-consumption lightweight steel construction column which has the capabilities of improving the explosionproof capability of a lightweight steel column, reducing the bearing capacity reduction caused by buckling failure of the lightweight steel column and preventing whole structure collapse caused by toppling of the lightweight steel column, thus avoiding person casualty accidents. A technical solution adopted by the invention is an explosionproof energy-consumption lightweight steel structure column which comprises the lightweight column, a foamed aluminum layer enclosed by steel plates, and a lightweight steel cover plate, wherein the steel column is positioned in an intermediate layer of the explosionproof energy-consumption lightweight steel structure column; the foamed aluminum layer enclosed by the steel plates comprises a first foamed aluminum filling layer and a steel sleeve, wherein the steel sleeve consists of mutually connected steel plates which encircle a steel column; the first foamed aluminum filling layer is arranged between the steel sleeve and the steel column.

Description

technical field [0001] The invention belongs to the technical field of buildings, in particular to an anti-explosion energy-consuming light steel structural column. Background technique [0002] In my country, light steel structures are mostly used in single-story and multi-story factory buildings, 2-3-story light steel structure hotels, office buildings, and multi-story residential buildings in earthquake-stricken areas. However, light-weight steel structure buildings are sensitive to blast impact loads, and their anti-blast performance is relatively poor. As the most important load-bearing component of light-gauge steel structure, light-gauge steel column, under the action of blast impact load, its resistance is significantly reduced. Once damaged, it may cause a chain reaction and lead to the collapse of the entire building structure. Therefore, the blast-resistant design of light steel columns is very important.

Problems solved by technology

However, light steel structure buildings are sensitive to blast impact loads, and their anti-blast performance is relatively poor.

As the most important load-bearing component of light steel structure, the light steel column has a significantly lower resistance under the impact load of the explosion. Once damaged, it may cause a chain reaction and lead to the collapse of the entire building structure.
