Steel structure unit room connecting system based on wedge-shaped blocks and integral connecting plates

Abstract

A steel structure unit room connecting system based on wedge-shaped blocks and an integral connecting plate comprises the connecting plate, an upper column corner fitting bottom plate, a lower column corner fitting top plate, the wedge-shaped blocks, long bolts and nuts. The wedge-shaped blocks are arranged between the upper column corner fitting bottom plate and the shear key on the upper face of the connecting plate and between the lower column corner fitting top plate and the shear key on the lower face of the connecting plate, long round holes are formed in the connecting plate, and vertical through round holes are formed in the wedge-shaped blocks. The long bolt penetrates through the upper wedge-shaped block, the lower wedge-shaped block and the middle connecting plate to connect the upper column corner piece bottom plate and the lower column corner piece top plate through the nut, then the upper column corner piece and the lower column corner piece are connected into a whole, and the vertical corner pieces are connected into a whole in the horizontal direction through the connecting plate. The device has the advantages of being clear in force transmission, good in integrity, convenient to install, capable of adjusting construction errors and the like.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a steel structure unit house connection system based on wedge blocks and integral connecting plates. Background technique [0002] Under the background of vigorously promoting the development of prefabricated buildings in my country, modular steel structure unit buildings have been gradually applied across the country. This kind of structure is a high-end product in prefabricated buildings, which has raised the level of building industrialization to a new height. development potential. The main unit of the steel structure unit building is made in the factory, including the structure, construction, water heating, electricity and rough decoration, etc., and the structure can be formed by simple assembly on the construction site. The efficiency and quality of on-site assembly play a vital role in construction speed and structural safety. [0003] For this kind of structure, wh...
