[0003] Currently, Chinese Utility Model with the publication number CN218028573U discloses a precast stair for prefabricated buildings, which includes a stair and two installation platforms. Reserved insertion bars are provided on both installation platforms. Reserved holes are opened at both the upper and lower ends of the stair. It also includes four first sliders, four second sliders and four connecting rods. A positioning column is arranged in the reserved hole. A positioning hole is opened along the height direction of the positioning column. The reserved insertion bar is inserted and matched with the positioning hole. Sliding grooves are opened on the four side walls of the positioning column. The sliding grooves are arranged along the length direction of the positioning column. A sleeve is arranged in the reserved hole. An activity hole is opened along the height direction of the sleeve. A horizontally arranged first annular groove is opened on the inner side wall of the activity hole. The first slider is slidably connected with the sliding groove. The second slider is slidably connected with the first annular groove. One end of the connecting rod is hinged with the first slider, and the other end of the connecting rod is hinged with the second slider. This application facilitates the alignment of the reserved hole and the reserved insertion bar and is convenient for installation.

The device installs the light strip through the light slot and installs the light wire through the provided wire slot, thereby effectively facilitating the concealed installation of the light strip and the light wire.

[0008] The present utility model is further configured such that anti-slip grooves are provided at the top of the steps.

[0009] By adopting the above technical solution: by providing the anti-slip grooves, the anti-slip effect can be effectively achieved.

[0010] The present utility model is further configured such that a first reserved hole is provided at the top of one end of the stair beam.

[0011] By adopting the above technical solution: by providing the first reserved hole, it can be effectively used in cooperation with the embedded steel bars.

[0012] The present utility model is further configured such that a second reserved hole is provided at the top of the other end of the stair beam.

[0013] By adopting the above technical solution: by providing the second reserved hole, it can be effectively used in cooperation with the embedded steel bars.

[0014] The present utility model is further configured such that steel bar meshes are embedded inside both the steps and the stair beam.

[0015] By adopting the above technical solution: by providing the steel bar meshes, the strength of the steps and the stair beam can be effectively enhanced.

[0016] In summary, the present utility model has the following beneficial effects:

[0017] 1. The user can socket the stair beam with the embedded steel bars through the first reserved hole and the second reserved hole, and then place the steps on the top of the stair beam, so that the clamping blocks are inserted into the inside of the clamping grooves, thereby effectively facilitating the rapid assembly of the device;

[0018] 2. The device installs the light strip through the light slot and installs the light wire through the wire slot, thereby effectively facilitating the concealed installation of the light strip and the light wire. BRIEF DESCRIPTION OF THE DRAWINGS
