Description

Technical Field

[0001] This utility model relates to the field of steel structure frame technology, and more specifically to a prefabricated steel structure frame. Background Technology

[0002] Steel frame structures are structures made primarily of steel and are one of the main types of building structures. Steel frame structures are characterized by high strength, light weight, and high rigidity, making them particularly suitable for constructing large-span, super-high, and super-heavy buildings. The material has good homogeneity and isotropy, making it an ideal elastic body that best conforms to the basic assumptions of general engineering mechanics. In addition, for ease of transportation, steel frame structures are assembled on the construction site.

[0003] An existing prefabricated steel structure frame for buildings, patent publication number CN118911281B, uses a first bolt to install the mounting components onto the mounting plate and crossbeams. After installation, a limiting component limits the universal ball joints, thereby installing the crossbeams. The universal ball joints, which can move and change angles, cooperate with the mounting plate, effectively improving the installation efficiency of the crossbeams and their utilization rate. This prevents the crossbeams from slightly bending during disassembly or transportation, which could affect installation and reuse. Crossbeams within a certain length range can be repeatedly installed and reused, thus facilitating the reconstruction of steel structure frames in factory buildings.

[0004] However, the existing technical solutions mentioned above are prone to deformation of the steel frame structure after an earthquake, resulting in poor earthquake resistance. Utility Model Content
