Improved wall panel for constructional engineering

The utility model discloses an improved wall panel for constructional engineering. The two sides of the wall panel are integrally bent to form a fastening part and a fixing part; the fastening part is provided with a curled edge and a fastening convex side; the fixing part is provided with a clamping groove; the two inner sides of the clamping groove are sunken to form a neck portion; when the wall panel is combined with other wall panels, the fastening part of the wall panel is engaged in the clamping groove of the fixing part of the adjacent wall panel, and the curled edge and the fastening convex side are fastened to the two sunken inner sides of the corresponding clamping groove of the fixing part of the adjacent wall panel, respectively. According to the improved wall panel for constructional engineering, when the wall panel is combined with other wall panels, the fastening part of the wall panel is engaged in the clamping groove of the fixing part of the adjacent wall panel, and the curled edge and the fastening convex side are fastened to the two sunken inner sides of the corresponding clamping groove of the fixing part of the adjacent wall panel, respectively, and therefore, a joint-point-free joint wall is formed on the four sides of the building; the combined wall panel is light, firm and easy to mount, and more suitable for various buildings.
