Abstract
Provided is an assembly-type special-shaped composite wall made by thin-walled cold-formed steel. The assembly-type special-shaped composite wall is divided into three kinds including an L shape, a T shape and a cross shape. M-shaped horizontal edge members are connected with M-shaped vertical edge members by means of U-shaped connecting pieces. The M-shaped horizontal edge members are connected with a square steel tube by means of C-shaped connecting pieces. Due to the fact that different special-shaped middle frames are made by different positions of the C-shaped connecting pieces and the horizontal edge members are connected with the vertical edge members and the square steel tube by means of self-tapping screws, the special-shaped wall can bear horizontal load and vertical load at the same time. Displacement of a wall on the other side is restricted by the spatial torsional effect of the special-shaped wall so that the overall stability of the special-shaped wall is improved. The assembly-type special-shaped composite wall made by thin-walled cold-formed steel has following advantages: the assembly-type special-shaped composite wall is low in weight, high in bearing capability and production efficiency, great in assembly degree and low in cost and is endurable, sound-insulating, water-tolerant and is resistance to cracks and impact; and a connection mode of the assembly-type special-shaped composite wall is rapid in speed of construction and installation and low in installation cost and does require no scaffold.
