Abstract

The invention provides a reinforced cold-bent concrete-filled steel tube column, a structure system and a construction method. The reinforced cold-bent concrete-filled steel tubule column comprises asteel tube column main body and column concrete poured in the steel tube column main body; the steel tube column main body is made of steel tubes formed by cold bending, and holes are formed in the position, connected with a to-be-mounted structure beam, on the steel tube column main body; horizontal stiffening plates are arranged in the position, located on the upper sides and the lower sides ofthe holes, of the steel tube column main body; a first vertical stiffening plate is connected between the two horizontal stiffening plates; and penetrating holes are formed in the horizontal stiffening plates or the position between the horizontal stiffening plates and the steel tube column main body. According to the reinforced cold-bent concrete-filled steel tube column, the structure system andthe construction method, the technical problems that a traditional structure system is poor in fireproof and anti-seismic effect, low in construction speed and poor in construction quality are solved.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a reinforced cold-formed steel pipe concrete column, a structural system and a construction method. Background technique [0002] The industrialization of construction is the focus of national construction and development. In the "Several Opinions of the Central Committee of the State Council on Further Strengthening the Management of Urban Planning and Construction" (February 6, 2016), it is clearly pointed out that "vigorously promote prefabricated buildings" and "encourage construction enterprises to assemble construction, on-site assembly", "building a national-level prefabricated building production base", "increasing policy support, and striving to make prefabricated buildings account for 30% of new buildings in about 10 years". [0003] my country is a country with frequent earthquakes. Earthquake disasters are the natural disasters that cause th...
