The box column and the cross column are effectively reinforced by multiple layers of reinforcing ribs, thereby greatly improving the load-bearing capacity and supporting function of the entire steel structure.

Description

Technical Field

[0001] The invention relates to the technical field of building materials, and in particular to a process for combining a steel structure cross column and a box column. Background Art

[0002] CloudRail is increasingly being used in small and medium-sized cities and tourist attractions. The elevated rail beams use a steel box beam structure, which can be designed and manufactured into rail beams with larger spans. They can pass through some wide roads, intersections or rivers, which increases the rigidity of the rail beams and does not occupy a large area of ​​ground, thus freeing up ground transportation. As an important part of the entire rail transit, the steel box rail beams of the CloudRail have the advantages of high strength, large span, factory prefabrication, and more environmentally friendly on-site installation.

[0003] The connection between steel box girders is an important factor in ensuring the overall stability and safety of the steel structure. During the installation of steel box girders at this stage, the connection between various steel box girders is often achieved by welding the steel box girders to be connected. Since the outer side of the box track beam needs to be flush, it often requires more processing and anti-corrosion after welding. At the same time, the quality risk brought by the on-site welding of each joint is very high. This process of welding each section of the box beam together is difficult, time-consuming, and wastes a lot of materials. At the same time, the overall stability of the steel structure is relatively low. Moreover, general box columns are not only connected to box columns, but also to different other steel structure columns. How to combine and connect different types of steel structure columns is a practical problem that must be solved. Summary of the invention

[0004] The purpose of the present invention is to provide a combination process of a steel structure cross column and a box column. The steel structure combination of the cross column and the box column is formed by inserting the cross column into the box column and then connecting them by a fixing screw group to form a connection whole of the box column and the cross column. The connection is welded by laser welding to form a complete steel structure combination, which improves the stability and firmness of the connection between the cross column and the box column. The connection transition between the cross column and the box column is achieved by a transition connection, and the effective connection of two different types of steel structure columns is achieved, which avoids the box column and the cross column from being broken and separated. The box column and the cross column are effectively reinforced by multiple layers of reinforcement ribs, which greatly improves the load-bearing capacity and supporting effect of the entire steel structure.
