Description

Technical Field

[0001] The utility model relates to the technical field of staircase structures, in particular to an assembled staircase structure. Background Art

[0002] With the continuous development of the prefabricated building industry, prefabricated staircases have been widely used to improve the construction efficiency of indoor staircases. This includes the currently popular lightweight steel staircase. However, existing lightweight steel staircases generally use welded connections, which is inefficient to construct. Dismantling requires cutting and dismantling, which can easily damage the original staircase structure and prevents secondary use, resulting in certain drawbacks.

[0003] To this end, we combined the traditional mortise and tenon connection principle and designed a staircase structure assembled using the mortise and tenon connection relationship. The staircase can be quickly assembled through plug-in connection between structures and bolt fixation. It is suitable for indoor and outdoor staircase installation and is easy to assemble and disassemble, which can effectively improve construction efficiency. Utility Model Content

[0004] The purpose of the present invention is to provide an assembled staircase structure to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An assembled staircase structure includes a floor slab and a stair body. A dovetail tenon is provided on the front side of the upper end of the stair body, and a dovetail mortise corresponding to the dovetail tenon is opened on the side of the floor slab. The dovetail tenon is inserted into the dovetail mortise. A plurality of triangular support seats that are clamped with the bottom of the stairs are provided at the bottom of the stair body, and a support column is provided at the bottom of the triangular support seat.

[0007] As a further preferred solution of the present invention: a positioning block is provided on the upper end surface of the triangular support seat, a positioning groove is provided at the bottom of the stair body, and the positioning block is inserted into the positioning groove.

[0008] As a further preferred solution of the present invention: a fixing bolt is threadedly connected to the bottom of the triangular support seat, and the fixing bolt passes through the triangular support seat and is threadedly connected to the stair body.

[0009] As a further preferred solution of the present invention: the uppermost triangular support seat is fixedly connected to the floor slab.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The assembled staircase structure adopts the combination of dovetail tenons and dovetail mortise and tenons, which can quickly achieve the docking of the staircase body and the floor slab, and through the design of triangular support seats and support columns, the staircase body can be effectively supported and fixed. At the same time, bolts are used for fixing to ensure the stability and firmness of the stairs after installation. The assembled stairs are highly safe and easy and quick to disassemble and assemble. The staircase structure can be applied to a variety of prefabricated assembled stairs such as wooden stairs and light steel stairs, which greatly improves the construction efficiency of assembled stairs and is highly practical.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0019] See also Figure 1-5, this embodiment provides an assembled staircase structure, including a floor 1 and a stair body 2, a dovetail tenon 5 is provided on the front side of the upper end of the stair body 2, and a dovetail mortise 7 corresponding to the dovetail tenon 5 is opened on the side of the floor 1, and the dovetail tenon 5 is inserted into the dovetail mortise 7. The bottom of the stair body 1 is provided with a plurality of triangular support seats 3 that are clamped with the bottom of the stairs, and a support column 4 is provided at the bottom of the triangular support seat 3; in order to enable the triangular support seat 3 to be quickly clamped with the stair body 1, a positioning block 8 is provided on the upper end surface of the triangular support seat 3, and a positioning groove 9 is opened at the bottom of the stair body 2, and the positioning block 8 is inserted into the positioning groove 9; in order to ensure the stability of the stair body 1 after assembly, a fixing bolt 6 is threadedly connected to the bottom of the triangular support seat 3, and the fixing bolt 6 passes through the triangular support seat 3 and is threadedly connected to the stair body 2.

[0020] In practical applications, in order to make the stair body 1 more stable after assembly, it is necessary to ensure the stability of the top connection of the stair body 1. Therefore, preferably, the topmost triangular support seat 3 is fixedly connected to the floor 1. In actual processing, the two only need to be connected and fixed by conventional connection methods familiar to those skilled in the art, such as welding, and this application will not go into details.

[0021] During the actual construction of the assembled staircase, the floor 1 is first fixed to the corresponding indoor or outdoor wall. The fixing method is a conventional design familiar to technical personnel in this field, and this application does not limit it and elaborate on it; then, the dovetail tenon 5 of the stair body 2 is inserted into the dovetail mortise 7 of the floor 1, and then a plurality of triangular support seats 3 with support columns 4 are inserted into the corresponding positions at the bottom of the stair body 2, and the topmost triangular support seat 3 is connected to the floor 1 by welding, and then the fixing bolts 6 are screwed into the bottom of the triangular support seat 3 to fix the triangular support seat 3 to the stair body 2; the fixing bolts 6 are located at the bottom of the stair body 2, which ensures the stability of the stair body 2 while not affecting the overall appearance. The design is scientific and reasonable.

[0022] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and technical features of the present application.
