Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an attached staircase temporary railing column fixing structure. Background Art

[0002] During the construction or decoration stage of the building structure, temporary railings need to be installed on the edges of the stairs to protect safety during the construction period.

[0003] For setting up temporary railings on the side of stairs, the existing practice is to drill holes in the cast-in-place structure and install expansion bolts to fix the footings of the railing columns to the structure. This implantation fixing method will destroy the staircase structure when making steel structure stairs or prefabricated stairs, causing technical difficulties in the setting and installation of temporary railing columns.

[0004] In order to ensure production safety and improve the safety facilities on the edge of the stairs, an innovative fixed structure for temporary railing columns in attached stairwells was developed to solve the problem of installing railing columns on steel structure stairs or prefabricated stairs. Utility Model Content

[0005] In view of the above problems existing in the prior art, the utility model aims to provide an attached staircase temporary railing column fixing structure. The application of this fixing structure solves the technical difficulty of not being able to install columns on steel structure stairs or prefabricated stairs, and is simple to manufacture, convenient to install and reliable to use.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model discloses an attached temporary staircase railing column fixing structure, which relies on the staircase slab, is additionally provided with an attached structure, and railing column installation points are arranged on the attached structure.

[0008] An attached temporary staircase railing column fixing structure includes an upper corner plate, a lower corner plate and a locking mechanism arranged between the upper corner plate and the lower corner plate. The locking mechanism can achieve a fixed connection between the upper corner plate and the lower corner plate, and can also adapt to stair slabs of different thicknesses.

[0009] Furthermore, the locking mechanism includes an inclined tube, a screw and a double nut. The inclined tube is fixedly arranged on the side of the upper angle plate, the screw lower angle plate is fixedly arranged on the side of the lower angle plate, and the screw is passed through the inclined tube and fixed by the double nut. The connection between the upper angle plate and the lower angle plate is achieved through the locking mechanism, providing an installation point for the railing column without damaging the building structure, and can be recycled.

[0010] Furthermore, a socket pipe is provided on the top surface of the upper angle plate for socket-fitting with a temporary railing column, thereby facilitating the installation of the temporary railing.

[0011] Furthermore, the upper corner plate is clamped on the upper opening of the side of the step, and the lower corner plate is clamped on the lower opening of the side of the stair section beam plate. The utility model relies on the conventional structure of the building body to achieve structural non-destructive attachment.

[0012] Furthermore, the inclined tube is obliquely intersected with the tread surface, and its axial line is perpendicular to the bottom surface of the ladder plate, so as to achieve installation cooperation with the screw rod.

[0013] Furthermore, the socket pipe is vertical to the step surface, which facilitates the smooth installation of the temporary railing.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1) Easy installation and disassembly: The attachment structure of the utility model can be quickly fixed with bolts, and the railing uprights only need to be inserted into the socket pipe to install the entire railing.

[0016] 2) Wide scope of application: The utility model can be used on steel structure stairs, prefabricated stairs, and cast-in-place stairs, and its use function is universal.

[0017] 3) High degree of toolization: The utility model can be installed and dismantled repeatedly without loss or damage.

[0018] 4) Safety management benefits: By applying the utility model, edge railings can be installed in the stairwell in a timely manner to ensure production safety.

[0019] 5) Low cost: The utility model has low production cost and can be used as a tool for long-term turnover. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention is further described below in conjunction with the embodiments and drawings of the specification, but the protection scope of the present invention is not limited thereto:

[0027] like Figure 1 As shown, an attached temporary staircase railing column fixing structure comprises a lower angle plate 1, a screw rod 2, an upper angle plate 3, an inclined pipe 4, a socket pipe 5, and a double nut 6.

[0028] For the lower angle plate 1, use angle steel with specifications of 70mm×70mm×5mm and a cutting length of 50-100mm. When installing, the angle steel mouth is stuck at the lower mouth of the side of the ladder beam plate. Figure 5 shown.

[0029] Screw 2, use 20mm round steel with thread at one end, the length is determined according to the actual height of the ladder beam, generally 280mm long, such as Figure 4 shown.

[0030] For the upper angle plate 3, use angle steel with specifications of 70mm×70mm×5mm and a cutting length of 200mm. When installing, the angle steel mouth is stuck on the upper mouth of the side of the step and is parallel to the step surface. Figure 5 shown.

[0031] The inclined tube 4 is a round tube with an inner diameter of φ22-φ25 and a cutting length of 100mm. It is welded obliquely on the outside of the upper angle plate 3 and is obliquely crossed with the step surface. Its axial line is perpendicular to the bottom surface of the ladder plate. Figure 5 shown.

[0032] The bell-and-spigot pipe 5 is a round pipe with an outer diameter of φ42, and the lower end is vertically welded to the side of the upper angle plate 3, and is in a vertical state with the step surface. When in use, the vertical pole of the temporary railing is sleeved on the outer periphery of the bell-and-spigot pipe 5, such as Figure 2 , 3 shown.

[0033] The temporary railing column fixing structure is assembled by clamping the angle steel mouth of the lower angle plate 1 at the lower mouth of the side of the stair section beam plate, and the screw 2 welded on the lower angle plate passes through the inclined tube 4 welded on the upper angle plate 3 and is fastened with a double nut 6. Under the action of the tightening force of the nuts, the lower angle plate 1 and the upper angle plate 3 are firmly attached and fixed to the side of the stair plate, and the socket pipe 5 welded on the side of the upper angle plate 3 is used as the installation point of the railing column.
