US Patent 10006212 Assembled house

An assembled house has a house framework, a roof framework, wall panels and a roof panel. The house framework has multiple beams, columns, and connectors. The roof framework has multiple rafters. Each one of the connectors is mounted securely in the column, and has multiple screw sleeves mounted securely in a concrete body. Thus, the beam can be connected securely to the column by screws screwed into the screw sleeve of the connector. Welding is not required for assembling the house framework on the site of the assembled house, thereby effectively accelerating the assembling. In addition, the beams and the columns are connected without welding, which eliminates the problem that the welded portions may easily rust. Furthermore, the columns, rafters, and the beams are hollow tubes, which can effectively lower the weight of the whole assembled house.
