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

Referring to fig. 1, the stair 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 prefabricated plate, the base plate 1 can be divided into two parts, namely, an upright base plate 1 and a horizontal base plate 1 according to the stair step form, the tread plate 2 is adhesively fixed on the horizontal base plate 1, and the vertical plate 3 is adhesively fixed on the upright base plate 1. The tread plates 2 and the riser plates 3 are also spliced together on the base plate 1 to form a stairway unit of one of the unit assemblies in the fabricated 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 this process, the base sheet 1 is first divided into a horizontal base sheet 1 and an upright base sheet 1 according to the installation posture of the base sheet 1. 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 I-shaped connecting piece 5 and the closing-in piece 6 are nailed and fixed on the base plate 1 subsequently, even if the screws penetrate through the base plate 1, the installation of the stair panel cannot be influenced.

In summary, only two factors of installation flatness and adjustment of the size of the base plate 1 are considered when installing the base plate 1, so that the installation requirement is greatly reduced, and a convenient foundation is provided for the installation of the stair panel.

Because the tread 2 and the vertical plate 3 are both stair surface plates, the materials and the manufacturing process are extremely high due to the requirement of aesthetic property, and if the size structure of the vertical plate 3 or the tread 2 is adjusted on site, the adjustment operation is troublesome; once a fault occurs, the vertical plate 3 or the tread plate 2 can be directly scrapped in a whole block. Therefore, when the base plate 1 is installed, the size of the base plate 1 is cut and adjusted and the size of the base plate 1 is measured and recorded, so that a technician can reversely calculate the size and the required quantity of the step plates 2 and the upright plates 3 to be installed according to the originally measured size of the base plate 1 in the later period when the step plates 2 and the upright plates 3 are installed, and the size precision error of the step plates 2 and the upright plates 3 prefabricated based on the measurement data can be controlled in a minimum range, thereby avoiding the operation of adjusting the size of the step plates 2 or the upright plates 3 again in the field installation process.

Referring to fig. 1, it can also be seen that, based on the structural characteristics of the stairway unit in the present application, in the installation process of the tread plate 2 and the vertical plate 3, the present application can further accommodate the dimension error of the tread plate 2 and the installation dimension error of the vertical plate 3 by respectively adjusting the installation positions of the tread plate 2 and the vertical plate 3, so as to obtain higher installation quality.
