Abstract

The invention relates to a wall surface structure based on a hidden screw connection mode The wall surface structure based on the hidden screw connection mode comprises a gypsum board, glass fiber cotton, a polyurethane sandwich composite board, step boards and a cold-formed thin-walled steel stand column, wherein the gypsum board and the polyurethane sandwich composite board are arranged in parallel at an interval, the cold-formed thin-walled steel stand column is arranged between the gypsum board and the polyurethane sandwich composite board, the cold-formed thin-walled steel stand column is connected with the gypsum board and the polyurethane sandwich composite board correspondingly, the space between the gypsum board and the polyurethane sandwich composite board is filled with the glass fiber cotton, the number of the step boards is multiple, and the multiple step boards are buckled up and down to form a whole and located on the outer side of the polyurethane sandwich composite board; the step boards and the polyurethane sandwich composite bpard are connected through screws, and the screws are located at the buckling position of the upper step board and the lower step board and are of a hidden structure. Compared with the prior art, the wall surface structure is rapid and convenient to install, short in construction period and good in comprehensive benefit, and has the advantage of good cost performance.

Description

technical field [0001] The invention relates to a wall structure, in particular to a wall structure based on a hidden screw connection method. Background technique [0002] The traditional cold-formed thin-walled steel exterior wall system consists of gypsum board 11, glass fiber cotton 12, Ozon board 13, moisture-proof paper 14, XPS insulation board 15, cold-formed thin-walled steel column 16, Z-shaped folding parts 17, and outer decorative layer 18 composition, see figure 1 , gypsum board 11, glass fiber cotton 12, Ozon board 13, moisture-proof paper 14, XPS insulation board 15, moisture-proof paper 14, and outer decorative layer 18 are sequentially laid in layers, and the cold-formed thin-walled steel column 16 is embedded in In the glass fiber cotton 12, and one side of the cold-formed thin-walled steel column 16 is connected with the gypsum board 11 by screws, and the other side is connected with the Ozon board 13 by screws, and the Z-shaped folding part 17 is embedded...
