The invention relates to a clamped assembly type stair panel mounting system, which is taken as a specific embodiment of the invention, and aims to realize the assembly type mounting of a stair panel.

Referring to fig. 1, the stairway unit in this embodiment includes a base plate 1, a tread plate 2, and a vertical plate 3, wherein the base plate 1 is directly laid on the stair step precast slab, and the tread plate 2 and the vertical plate 3 are respectively installed on two exposed surfaces of the base plate 1 in a snap-fit manner, thereby forming a stairway unit which is one of the unit components in the assembled stairway panel installation system.

In conjunction with fig. 1 and 2, to achieve the effect of quick installation. In this embodiment, the base plate 1 is set as a single straight plate, after cement is built on the stairs, the base plate 1 is laid on the surface layer of the stairs one by one while the cement is not dried, and meanwhile, the base plate 1 is leveled. In the process, the base plate 1 can be selected from the composite plates which have relatively low cost and relatively low construction requirement and are convenient for adjusting the cutting size, so that when the base plate 1 is installed, the installation posture of the base plate 1 is adjusted or the size condition of the base plate 1 is improved, the base plate 1 is convenient to install, and convenience is provided for the installation of the subsequent step plate 2 and the vertical plate 3. In addition, because the base plate 1 belongs to the inner plate, technicians can not have too high technical requirements when installing the base plate 1, and even the requirement on the accuracy of the installation position of the base plate 1 is reduced. Similarly, when the clamping groove body 5 is subsequently fixed on the base plate 1 by nailing, even if the screw structure damages the base plate 1, the worry is not too great.
