The middle cover plate is connected through an easily detachable bevel and an L-shaped connecting piece arranged on the easily detachable bevel. The L-shaped connecting piece is arranged on the left-sealed cover plate, the middle cover plate and the right-sealed cover plate, and an observation port is arranged on the front side of the middle cover plate.

[0008] Connection holes for connecting with the wall panel are opened on the upper end plates of the left-sealed cover plate and the right-sealed cover plate.

[0009] The left-sealed cover plate, the middle cover plate and the right-sealed cover plate are all in contact with the concrete. Connection holes are opened on the upper end plates of the left-sealed cover plate and the right-sealed cover plate, and they are connected with the wall panel through pins and pin plates. Because the stair tread plus the cover plate body is relatively enclosed, it is easy for the concrete to be vibrated in place inadequately. During pouring, the observation port can be opened to check the situation, or the concrete can be vibrated at the observation port.

[0010] Preferably, pin holes are opened on the L-shaped connecting piece, and adjacent two L-shaped connecting pieces are fixed by passing pins through the pin holes and using pin plates.

[0011] Preferably, the L-shaped connecting piece is integrally formed with the left-sealed cover plate, the middle cover plate and the right-sealed cover plate; or the L-shaped connecting piece is welded on the left-sealed cover plate, the middle cover plate and the right-sealed cover plate.

[0012] Preferably, the easily detachable bevel is an eight-shaped easily detachable bevel, and the L-shaped connecting piece is integrally formed on the edge of the easily detachable bevel or the L-shaped connecting piece is welded on the edge of the easily detachable bevel. Because both sides of the cover plate body are concrete, the cover plate body is squeezed to death and cannot be removed. Therefore, the cover plate body is disassembled into three parts, and by designing it as an eight-shaped easily detachable bevel, each part of the cover plate body can be easily removed during the construction process.

[0013] Preferably, both the left-sealed cover plate and the right-sealed cover plate are provided with reinforcement holes and air vents. The reinforcement holes are mainly used for the screw to pass through this hole to reinforce the tread cover plate, preventing the cover plate body from floating and bulging during the concrete pouring process and ensuring the quality; a large number of air bubbles are easily generated during the concrete pouring process. After the cover plate body is connected and reinforced, the airtightness is good and the air bubbles cannot be discharged. Through the air vents, the air bubbles can be better discharged to ensure the forming quality.

[0014] Preferably, lower splicing holes are provided on the front sides of the left sealing cover plate, the middle cover plate, and the right sealing cover plate, and upper splicing holes corresponding to the lower splicing holes are provided on the rear top plates of the left sealing cover plate, the middle cover plate, and the right sealing cover plate.

[0015] Preferably, two adjacent left sealing cover plates, middle cover plates, and right sealing cover plates are spliced by passing a pin through the lower splicing hole and the upper splicing hole and fixing with a pin piece.

[0016] Between two adjacent cover plate bodies, between the wall panel and the cover plate body, and between the easily detachable beveled openings are all connected by pins and pin pieces.

[0017] 1. The utility model can completely replace the traditional two-side dog teeth and the middle step cover plate. One template is formed from the original three templates, eliminating the complex corner templates of the dog teeth, reducing the production process of the dog teeth, saving materials and facilitating the operation of workers. The production difficulty and cost will both be reduced, and the utility model can be reused, making the application more flexible and convenient;

[0018] 2. The left sealing cover plate, the middle cover plate, and the right sealing cover plate of the utility model are all in contact with the concrete surface, and the upper end plate is connected to the wall panel. Since the staircase step plus the cover plate is relatively enclosed, it is easy for the concrete to be vibrated inadequately. During pouring, this observation port can be opened to check the situation, and vibration can also be carried out at this observation port. Because both sides of the two cover plates are concrete, this cover plate is squeezed and cannot be removed. Designing it as an eight-shaped easily detachable beveled opening can facilitate removal during construction;

[0019] 3. Between the cover plates of the utility model, between the wall panel and the cover plate, and between the easily detachable beveled openings are all connected by pins and pin pieces. The reinforcement holes are mainly used for the screw to pass through this hole to reinforce the step cover plate, preventing the cover plate from floating and bulging during the concrete pouring process and ensuring the quality; during the concrete pouring process, a large amount of air bubbles are easily generated. After the cover plate body is connected and reinforced, the airtightness is good, and the air bubbles cannot be discharged. Then, the air bubbles can be better discharged through the air holes, ensuring the forming quality. BRIEF DESCRIPTION OF THE DRAWINGS
