Description

Technical Field

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. At the same time, steel structure components can be mainly divided into four categories: beams, columns, plates and connectors.

[0003] For example, a prefabricated large-span steel structure component of Chinese patent application number CN202223158819.X relates to the technical field of prefabricated steel components. The utility model includes a first steel structure and a second steel structure. The first steel structure and the second steel structure both include a first assembly frame and a second assembly frame on their circumferential sides. The first steel structure and the second steel structure are welded with extension vertical plates on both sides. An extension horizontal plate is welded on one surface of the extension vertical plate. Assembly frames are welded at both ends of the first assembly frame and the second assembly frame. By setting the first assembly frame and the second assembly frame, the device can slide the assembly frames on the first assembly frame and the second assembly frame around the first steel structure and the second steel structure, and further use positioning screws to connect and fix the connecting plates on the two assembly frames. At this time, the two positioning plates on the second assembly frame are against the first assembly frame to form a triangular structure, thereby preventing the first assembly frame and the second assembly frame from deforming and affecting the installation effect.

[0004] However, in actual use, the steel structures can only be fixed to each other in the horizontal direction or the vertical direction through the above-mentioned device, and the fixing angle cannot be adjusted according to the actual situation, which reduces the stability of the overall device.
