Description

Technical Field

[0001] The utility model belongs to the technical field of building structures, and in particular relates to an assembled steel structure support beam. Background Art

[0002] Steel structure is a building technology that features a skeletal frame of vertical steel columns and horizontal I-beams, constructed in a rectangular grid to support the building's floors, roof, and walls, which are attached to the frame.

[0003] Most of the existing support beams are steel structures, which are convenient for construction, high in strength, and improve safety performance. However, the existing steel structure support beams have the following disadvantages:

[0004] 1. The longitudinal beam is an integral type, and a large crane is required to lift the longitudinal beam vertically during installation. At this time, the longitudinal beam is prone to swing left and right during operation of the crane, which has poor stability and is prone to accidents. In addition, large cranes are limited by the site. At the same time, the longitudinal beam and the base are welded. When fixing the base, the base needs to be aligned with a fixed position, and the base needs to be pulled during alignment, which causes the longitudinal beam to shake. This is very complicated to operate and wastes time.

[0005] Second, the beam cannot be installed in a positioned manner during installation, which makes it easy for it to loosen after use. This reduces the load-bearing capacity of the beam, resulting in poor overall structural stability and prone to safety accidents. Summary of the invention

[0006] To solve the problems raised in the background technology, the purpose of the utility model is to provide a prefabricated steel structure support beam, which adopts an assembly method to achieve rapid installation and has high stability after installation, thereby improving safety performance.
