Description
Technical Field
[0001] The utility model relates to the field of prefabricated stairs, and more specifically, to an assembled building prefabricated staircase. Background Art
[0002] Prefabricated stairs are used in house construction. Existing prefabricated stairs are generally formed by using connecting plates and stairs and then pouring them. This makes it easy for the stairs to be subjected to external forces for a long time, causing gaps or slippage, resulting in unstable connections between the stairs. For this reason, we propose an assembled building prefabricated staircase. Utility Model Content

The device has a simple structure and is easy to use.
[0005] 2. Technical solution
[0006] To solve the above problems, the utility model adopts the following technical solutions.
[0007] A prefabricated staircase for assembled buildings comprises a support plate, a mounting block is installed at the lower end of the support plate, the mounting block is provided with two symmetrically arranged docking grooves, a top plate is installed at the upper end of the support plate, a docking block is installed on the side wall of the top plate, the support plate and the docking block are both provided with two symmetrically arranged slots, docking rods are inserted into the slots, and two symmetrically arranged retaining plates are installed on the side wall of the docking block.
[0008] Furthermore, the retaining plate is adapted to the docking slot, and the center line of the retaining plate and the center line of the docking slot are in the same vertical plane, so that the retaining plate and the docking slot can be snapped together to maintain stability.
[0009] Furthermore, the height of the docking block is the same as that of the mounting block, and the width of the docking block is adapted to the gap between the mounting block and the support plate, so that the gap between the mounting block and the support plate can be adapted to the shape of the docking block.
[0010] Furthermore, the retaining plate is configured to be L-shaped, and the height of the retaining plate is 3 cm higher than the height of the docking slot, so that the retaining plate can be easily clipped into the docking slot.
[0011] 3. Beneficial effects

[0018] The following will combine the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments in the utility model belong to the scope of protection of the utility model.
[0019] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0020] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0021] Example 1: Please refer to Figure 1 and Figure 2A prefabricated staircase for assembled buildings includes a support plate 1, a mounting block 2 is installed at the lower end of the support plate 1, the mounting block 2 is provided with two symmetrically arranged docking grooves 3, a top plate 6 is installed at the upper end of the support plate 1, a docking block 7 is installed on the side wall of the top plate 6, the support plate 1 and the docking block 7 are both provided with two symmetrically arranged card slots 4, the card slots 4 are plugged with docking rods 5, and the side walls of the docking block 7 are provided with two symmetrically arranged retaining plates 8.
