The vertical wall structure generally takes the inner transverse wall as the bearing wall of the structure, and the wall column is a C-shaped light steel member, the wall thickness of which is determined according to the load to be received, usually 0.84-2 mm, 600 mm. The lower end of the wall column is a bottom slot beam with a U-shaped opening facing upward. The upper end of the wall column is a top slot beam with a U-shaped opening downward, and the joist is fixed on the side edge of the upper slot beam. In order to improve the stability of the wall column, the general wall column height set three light steel pull bar. This wall structure arrangement, can effectively bear and reliable transmission of vertical load, and easy to arrange, but the wall structure can not afford horizontal load.
