Description

An anti-explosion energy-consuming light steel structural column

technical field

The utility model belongs to the technical field of buildings, in particular to an anti-explosion energy-consuming light steel structural column.

Background technique

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 member of light-weight steel structure, the resistance of the steel column is significantly reduced 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. Therefore, the anti-blast design of steel columns is very important.

Contents of the invention

In order to overcome the defects of the prior art, the utility model aims to provide a steel column that can improve the anti-knock ability, reduce the load-carrying capacity drop caused by the buckling damage of the steel column, and prevent the overturning of the steel column from causing the overall The structure collapses, thereby avoiding casualty accidents with anti-explosion energy-consuming light steel structural columns.

The technical solution adopted by the utility model is an anti-explosion energy-consuming light steel structural column, which includes a steel column, a foamed aluminum layer surrounded by steel plates and a light steel cover plate. The middle layer of the structural column, the aluminum foam layer enclosed by the steel plate includes the first aluminum foam filling layer and a steel sleeve, the steel sleeve is formed by connecting steel plates, and the steel sleeve is enclosed outside the steel column, The first foamed aluminum filling layer is arranged between the steel sleeve and the steel column.

The mid-span H/3 area of the steel column is filled with a second foamed aluminum filling layer, and light steel cover plates are arranged at both end sections of this area.

The light steel cover plate includes a welded joint and a light steel plate, and the second foamed aluminum filling layer filled in the H/3 area of the middle span of the steel column is surrounded by the steel plate enclosure by using the light steel cover plate through the welded joints arranged at the four corners of the light steel plate The aluminum foam layer is welded and connected.

Compared with the prior art, the utility model has the beneficial effects that: through the physical characteristics of energy consumption and energy absorption of the aluminum foam layer, the tensile capacity of the steel sleeve is added in the H/3 area of the middle span of the steel column Foam aluminum energy-absorbing material, combined into a "sleeve-wrapped sandwich" type anti-explosion energy-absorbing rectangular steel column, increases the bending stiffness of the rectangular steel column and effectively prevents buckling failure in the mid-span area of the rectangular steel column, thereby improving its performance. The vertical bearing capacity can avoid damage and damage to the people and facilities inside the house.

detailed description

As shown in Figures 1-3, an anti-blast energy-consuming light steel structural column includes a steel column 1, a foamed aluminum layer 2 surrounded by steel plates and a light steel cover plate 4, and the steel column 1 is located at the The middle layer of the light steel structure column, the aluminum foam layer 2 enclosed by the steel plate includes the first aluminum foam filling layer 21 and the steel sleeve 22, the steel sleeve 22 is formed by connecting steel plates, and the steel sleeve 22 is enclosed outside the steel column 1, and the first foamed aluminum filling layer 21 is arranged between the steel sleeve 22 and the steel column 1.

The mid-span H/3 region of the steel column 1 is filled with a second foamed aluminum filling layer 3, and light steel cover plates 4 are arranged at both ends of the region.

The light steel cover plate 4 includes a welded joint 41 and a light steel plate 42. The light steel cover plate 4 is used to fill the second aluminum foam in the H/3 area of the steel column through the welded joints 41 arranged at the four corners of the light steel plate 42. The filling layer 3 is welded to the aluminum foam layer 2 of the steel plate enclosure.
