Abstract

The invention relates to a self-returning center supporting system for a frame, and belongs to the field of structure engineering. The system comprises two welding combination square steel pipe columns, two square steel pipe center columns provided with suspension arm beam sections, an I-shaped beam section provided with an inclined supporting rod, two buckling preventing supports, a combined self-returning device and a plurality of connecting devices. According to the system, the combined self-returning device composed of a pulling cable, a tool and a beam-column joint connecting device is additionally arranged, so that the overall bearing capacity of a joint can be effectively improved, and moreover, the overstress load, due to excessively high pre-tension of the pulling cable, to the I-shaped beam section in the combined self-returning device can be avoided; the buckling preventing supports are arranged between a beam and a column, so that the overall stability of the frame and theenergy consumption capacity can be improved; the working pressure of the pulling cable is reduced; and the frame structure system is promoted to self-return.

Description

technical field [0001] This patent relates to a self-resetting frame center support system, which belongs to the technical field of structural engineering. Background technique [0002] The prefabricated steel structure building system has become a new direction and new trend in the development of building steel structures. It has the advantages of standardization of design, factory production, assembly of construction, energy saving and environmental protection of green buildings, etc. Among them, the connection method of components occupies an important part. Traditional steel frames often use welding during on-site construction. However, due to the complex environment of the construction site, the construction quality of welding is difficult to grasp. Bolt connection can better control the construction quality, but there are certain design constraints. difficulty. How to leave the welding work in a factory with a better working environment, and only perform bolt connect...
