Anti-deformation crisscross column

Abstract

The invention relates to an anti-deformation crisscross column. An H-shaped steel structure is cut along the centre line to form two pieces of T-shaped steel, the two pieces of T-shaped steel are welded to form a crisscross column, the H-shaped steel structure is cut along the center line to form a cutting line, the connection is kept along the center line to form a connecting part, and then the H-shaped steel structure is cut along the center line to form a cutting line, the cutting operation is carried out repeatedly for times, and finally the two pieces of T-shaped steel connected in a completely symmetric manner are finally formed. According to the anti-deformation crisscross column, the two pieces of T-shaped steel connected in a completely symmetric manner are formed through cutting, the two pieces of T-shaped steel are spliced into a crisscross column, and then the connecting part is cut open, so that the heating area is greatly reduced, the verticality and flexure are effectively guaranteed, and the structure can be utilized to machine a T-shaped column, a crisscross column, nonstandard channel steel, nonstandard large angle steel and the like.

Description

technical field [0001] The invention relates to a deformation-resistant cross column, which belongs to the technical field of steel structures. Background technique [0002] The steel structure cross column is an important structural column in the steel structure frame. In order to ensure the accuracy of the upper and lower columns and the connection bolt holes between the cross column and the beam during the on-site installation of the steel structure, the straightness, verticality and twist of the cross column Very demanding. If there is a deviation, it will make it difficult to align the holes during installation, which will increase the difficulty of on-site installation. The existing cross column processing technology is: adopt welding H-shaped steel to form a shape, cut from the center of the H-shaped steel web to form two T-shaped steels, and then splice them together. Although some anti-deformation measures have been adopted, due to the excessive heat deformation a...

Problems solved by technology

Although some anti-deformation measures have been adopted, due to the excessive heat deformation and the need to open double-sided grooves for full penetration welding, the heat will be greater. The two T-shaped steels cut cannot avoid heat deformation, so that after cutting The verticality of the two T-shaped steels is poor, and the distortion is serious

Moreover, due to the large thickness of the steel plate, it is difficult to correct it within the allowable error range after deformation, and it cannot even be spliced ​​into a cross column, which affects the quality of the components. This defect has always been a major obstacle restricting the processing of steel structures to produce cross columns.
