Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a floor-mounted prefabricated building all-steel frame structure. Background Technology

[0002] Prefabricated buildings refer to a construction method in which the main components of a building are prefabricated in a factory and then transported to the construction site for assembly. They are characterized by energy saving, environmental protection, and short construction period. In order to ensure the stability of the building, some prefabricated buildings require reinforcement and support of the interior, which requires the use of a full steel frame structure.

[0003] All-steel frame building structures refer to frame structures made of steel. They have many characteristics such as high strength, good rigidity, and good seismic performance.

[0004] However, in the actual installation and use of some prefabricated buildings with all-steel frame structures, the contact installation positions between the bottom of the internal support components and the ground are mostly limited, with single-point fixation. The stability is limited and the support strength is not high during long-term use, which is a deficiency and makes it inconvenient to fix and support the bottom of the all-steel frame structure.
