Abstract: A building information modeling (BIM)-based modular housing built with thin-wall channel steel can include columns and transverse beams adopt inward-flanging C-section steel or combined square steel arranged by oppositely buckling symmetric inward-flanging C-section steel. The columns and transverse beams are connected to each other together by base connectors, butting connectors, or crossed connectors. The joint is provided with webs, and can be used as a standard connector due to high strength, thereby realizing an internal-external nesting effect. A positioning groove arranged outside the joint and the inward-flanging C-section steel can be nested together in a concavo-convex manner, and then pressed and fastened by a fastening steel strip, thereby realizing effects of fastening and slippage prevention.

Abstract: The present disclosure discloses a building information modeling (BIM)-based modular housing built with thin-wall channel steel comprising foundations, columns, beams, walls, a roof plate, doors, and windows. The columns and transverse beams adopt inward-flanging C-section steel or combined square steel arranged by oppositely buckling symmetric inward-flanging C-section steel. The columns and foundations, the columns and transverse beams, adjacent transverse beams, the columns or transverse beams and slant beams, the transverse beams or slant beams and roof plate, and joints of adjacent supports are connected to each other together by base connectors, butting connectors, or crossed connectors. According to the technical solution of the present disclosure, the inward-flanging C-section steel can be quickly and securely butted, or combined square steel can be quickly and securely butted. The joint is provided with webs, and can be used as a standard connector due to high strength.
