Building wall surface

The utility model discloses a building wall surface, a shock absorption structure is installed on the building wall surface, a leakage-proof structure is installed at the upper end of the shock absorption structure, and the shock absorption structure comprises a first bolt, an installation frame, a second bolt, a nut and a spring. When the panel is impacted by external force, the impact force can be transmitted to the spring, the spring absorbs impact energy, the probability that the panel is damaged by the impact of the external force is effectively reduced, meanwhile, the foam rod is blocked by the limiting block and cannot be separated from the expansion joint, the structure is simple, the manufacturing cost is reduced, and the device is also suitable for a thin curtain wall plate. 本实用新型公开了一种建筑墙面，建筑墙面上安装有减震结构，减震结构上端安装有防漏结构，减震结构包含有：第一螺栓、安装架、第二螺栓、螺母以及弹簧，本实用新型涉及幕墙安装技术领域，本案的有益效果为：使用了减震结构与防漏结构，当面板遭受外力冲击时会将冲击力传递至弹簧处，弹簧吸收冲击能量，有效降低外力冲击对面板造成损坏的概率，同时泡沫棒受限位块阻挡，使其不会脱出伸缩缝内，结构简单，降低了制造成本，并且同样适用于较薄的幕墙板。
