Structural system and construction method of prefabricated cold-formed thin-walled steel composite house

Abstract

The invention provides a fabricated type cold-formed thin-walled shape steel combined building structure system and a construction method thereof, and belongs to the technical field of civil construction. The fabricated type cold-formed thin-walled shape steel combined building structure system comprises cold-formed thin-walled shape steel combined columns, cold-formed thin-walled shape steel combined beams and cold-formed thin-walled shape steel combined plates. Each cold-formed thin-walled shape steel combined column, each cold-formed thin-walled shape steel combined beam and each cold-formed thin-walled shape steel combined plate are correspondingly formed by connecting a plurality of U-shaped thin-walled shape steel after flanges are overlapped with flanges or the flanges are overlapped with web plates and are both provided with connecting surfaces connected with other parts, and formed cavities are filled with foam kind thermal insulation materials; and the cold-formed thin-walledshape steel combined beams are connected with the adjacent cold-formed thin-walled shape steel combined columns through bolts, and the cold-formed thin-walled shape steel combined plates are connected to the adjacent cold-formed thin-walled shape steel combined beams in a lap joint mode through pins. The fabricated type cold-formed thin-walled shape steel combined building structure system can solve the problems of lower number of floors, poorer structural stability, lower bearing capacity and the like of the thin-walled shape steel applied to buildings existing in the prior art.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and more specifically relates to a structural system and a construction method of an assembled cold-formed thin-walled steel composite house. Background technique [0002] Common building structures in engineering are generally brick-concrete structure, brick-wood structure, reinforced concrete structure and steel structure. The brick-concrete structure adopts brick walls, reinforced concrete beams, and slabs as the main load-bearing components, and is suitable for multi-storey buildings with small bay depth and small room area. The main load-bearing structure of the brick-wood structure is made of bricks and wood. The durability of the brick-wood structure is short and the building area is small. The main materials of reinforced concrete are steel bars and concrete. This structure has the widest application range and is also the most widely used building construction form. The concret...
