Problems solved by technology

A lot of welding is used in the construction of traditional steel structure residential buildings, the construction speed is slow, and the pollution to the environment is serious. The most important thing is that the quality of the welds is not suitable for control, which seriously affects the safety performance of the building.

Embodiment Construction

[0061] The present invention is described in detail below in conjunction with accompanying drawing:

[0062] as attached figure 1 As shown, the splicing position of the assembled steel plate of the present invention is set in the middle of the main girder, where the shear force and bending moment are relatively small. From the perspective of structural mechanics, the setting of the splicing position is reasonable.

[0063] as attached figure 2 As shown, in the prefabricated multi-story prestressed self-resetting steel special-shaped column frame structure system described in the present invention, the beams involved are shaped steel beams made of channel steel, which are divided into single-channel steel beams and double-channel steel beams. The channel steel beams are provided with connection holes at intervals of a fixed distance, which is convenient for splicing two single-channel steel beams into double-channel steel beams with bolts when the plates are spliced ​​togethe...

Abstract

The invention discloses a fabricated multistory and high-rise prestressed self-resetting steel frame structure system provided with special-shaped columns, and relates to the technical field of structural engineering. The fabricated multistory and high-rise prestressed self-resetting steel frame structure system comprises fabricated profile steel plates and fabricated special-shaped columns, wherein the fabricated profile steel plates comprise profile steel beams consisting of steel channels and floor slabs; the fabricated profile steel plates are prefabricated in a factory; at the construction site, the fabricated profile steel plates are mutually spliced with flange plates of the fabricated special-shaped columns through beam-end blanking plates of the fabricated profile steel plates, and layers of the fabricated special-shaped columns are spliced at the site by bolts, so that a multilayer profile steel plate steel-frame structure is formed; and the fabricated profile steel plates and the fabricated special-shaped columns are prefabricated in the factory and assembled at the construction site by bolts.

Description

technical field [0001] The invention relates to an assembled multi-story prestressed self-resetting steel special-shaped column frame structure system, which belongs to the technical field of structural engineering. Background technique [0002] my country's annual urban and rural housing area is 2 billion square meters, of which more than 80% are high-energy buildings, and the energy consumption per unit building area in my country is more than twice that of developed countries. According to the statistics of the China Iron and Steel Association, in 2011, my country's steel output exceeded 700 million tons, ranking first in the world's steel output for 16 consecutive years. Our country is less than 4%. As the country with the largest construction scale and steel output in the world, China lags behind seriously in the development of steel structures for houses (including residences). [0003] The implementation of my country's "Twelfth Five-Year Plan" has brought the constr...
