A special-shaped column device for a prefabricated steel structure building

Abstract

The invention discloses a special-shaped column device for an assembled steel structure building, and relates to the technical field of steel structure buildings. Including the special-shaped column body, the first beam and the second beam are movable on both sides of the special-shaped column body, the surface of the special-shaped column body is fixedly provided with a fixed box, and the inside of the special-shaped column body is provided with a first limiting device and a second limiting device. Positioning device, the internal activities of the fixed box are provided with positioning rods extending to the inside of the special-shaped column body, and the two ends of the positioning rods are respectively provided with unlocking devices. By arranging the first beam and the second beam to be inserted into the inside of the special-shaped column body, the first beam and the second beam will respectively press the first limiter and the second limiter, so that the first limiter and the second limiter The blocks will descend first and then rise, so that the tops of the first and second limit blocks enter the insides of the first beam and the second beam respectively, achieving the effect of preliminary positioning, which facilitates the follow-up positioning work.

Description

technical field [0001] The invention relates to the technical field of steel structure buildings, in particular to a special-shaped column device for assembled steel structure buildings. Background technique [0002] The prefabricated steel structure system refers to the building produced by making housing units or components according to the unified standard building parts specifications, and then transporting them to the construction site for assembly in place. It is characterized by light building weight, energy saving and environmental protection, fast construction speed, and high degree of industrialization. , can solve many problems such as the low level of construction industrialization in my country, low labor productivity in house construction and low quality of traditional house products, and adapt to the development of my country's construction industry. [0003] In the prior art, special-shaped columns of general steel structures are custom-cast, such customized s...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, special-shaped columns of general steel structures are custom-cast, such customized special-shaped columns can connect beams at different positions, and special-shaped columns and beams are connected by welding at the construction site, but such The connection method will lead to a decrease in installation efficiency, which will prolong the working time. At the same time, the special-shaped columns of the steel structure can be recycled, which makes it inconvenient to transport the whole formed by welding the special-shaped steel structure and the beam, which requires the staff to cut and disassemble it. , so that unnecessary labor will be wasted, in order to solve the above problems, the present invention provides a special-shaped column device for prefabricated steel structure buildings
