An industrially assembled column-through-type steel structure frame eccentric support system

Abstract

The invention discloses an industrial prefabricated eccentric bracing system with penetrating columns for a steel structural frame, and belongs to the technical field of structural engineering. The industrial prefabricated eccentric bracing system comprises prefabricated truss plates, prefabricated upright columns and eccentric bracing members; the prefabricated truss plates comprise floors and latticed truss beams with angle steel web members; the prefabricated truss plates are prefabricated in a factory and are spliced with beam-column joints of the prefabricated upright columns by beam-end sealing plates and on-beam cover plates of the prefabricated truss plates in a construction site; the prefabricated upright columns penetrate the beam-column joints, each upright column with the certain length can penetrate 4-5 stories, and the upright columns are spliced at inflection points, which have low stress, of middle columns of the stories by bolts in the site, so that a multilayer truss plate and steel frame structure is formed; the eccentric bracing members are connected to the bottoms or the tops of the truss beams of the prefabricated truss plates to be used as lateral-resistant members on the basis of the truss plate and steel frame structure; the prefabricated truss plates, the prefabricated upright columns and the eccentric bracing members are prefabricated in the factory and are assembled by bolts in the construction site.

Description

technical field [0001] The invention relates to an eccentric support system of an industrially assembled column through-type steel structure frame, belonging 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, my country's steel output exceeded 700 million tons in 2011, 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] At present, the systematic research on high-rise steel structure residences at home and abr...

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.

[0004] In the traditional steel frame structure system, the lateral rigidity of the structure is difficult to meet the requirements, the deformation is large, and it is easy to cause damage to non-structural components, and the advantages of steel structure housing have not been fully utilized.
