Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to an installation structure of a temporary guardrail for stairs. Background Art

[0002] During the construction of high-rise buildings, temporary protective devices are installed on the outer edges of concrete stair treads to prevent falls in order to provide a safe working environment for construction workers. However, after the main construction of the building is completed, all temporary protective devices need to be removed to facilitate the renovation of the staircase.

[0003] In traditional technology, temporary protective devices are usually fixed to the stair steps by welding or drilling holes and inserting expansion bolts. However, setting temporary guardrails on the top surface tends to take up a lot of space, which will squeeze the working space on the stair steps, seriously affecting the plastering, tiling, marble and decorative construction of the stair treads and the stair guardrails. At the same time, without good stair protection during decoration work, safety accidents are very likely to occur, causing adverse effects on the construction site. Utility Model Content

[0004] In order to solve the above problems existing in the prior art, the purpose of the present invention is to provide an installation structure for a temporary stair guardrail.

[0005] The technical solution adopted by this utility model is:

[0006] A mounting structure for a temporary stair guardrail comprises a supporting sleeve rod, a connecting rod and a mounting plate; mounting holes are provided at both ends of the supporting sleeve rod, and the connecting rod can be adjusted and mounted in the middle of the supporting sleeve rod; a mounting plate is provided at one end of the connecting rod.

[0007] Optionally, a plurality of positioning holes are provided on the mounting plate.

[0008] Optionally, the connecting rod is a screw rod, a first nut is provided on the mounting plate, and the other end of the connecting rod passes through the supporting sleeve rod and is locked by the nut.

[0009] The beneficial effects of the utility model are:

[0010] The utility model provides an installation structure for a temporary stair guardrail, comprising a support sleeve, a connecting rod, and a mounting plate; mounting holes are provided at both ends of the support sleeve, and the connecting rod can be adjusted and installed in the middle of the support sleeve; a mounting plate is provided at one end of the connecting rod. By providing a mounting plate in the middle of the support sleeve, when in use, the mounting plate is directly fixed to the side of the stairs from the side, and the columns at both ends of the temporary guardrail are directly inserted into the support sleeve. The columns are then locked into the support sleeve through the bolt assembly and the mounting holes, and the temporary guardrail can be fixed to the side of the stairs, thereby providing protection for the stairs while freeing up space on the stair step surface to the greatest extent, without affecting subsequent operations on the step surface. At the same time, when dismantling the utility model, the temporary guardrail can be removed by removing the bolt assembly on the mounting hole, making the entire process more convenient and quick.

[0017] In this embodiment, if Figures 1 to 4 The illustrated installation structure for a temporary stair guardrail includes a support sleeve 1, a connecting rod 2, and a mounting plate 3. Mounting holes 4 are provided at both ends of the support sleeve 1, and the connecting rod 2 is adjustably mounted in the middle of the support sleeve 1. A mounting plate 3 is provided at one end of the connecting rod 2. By providing the mounting plate 3 in the middle of the support sleeve 1, during use, the mounting plate 3 is directly secured to the side of the staircase. The columns 6 at both ends of the temporary guardrail are directly inserted into the support sleeve 1. The columns 6 are then locked into the support sleeve 1 via bolt assemblies and mounting holes 4, thereby securing the temporary guardrail to the side of the staircase. This provides protection for the staircase while also freeing up space on the stair step surface to the greatest extent possible, without affecting subsequent work on the step surface. Furthermore, during dismantling, the present invention can be removed by removing the bolt assemblies in the mounting holes 4, making the entire installation and dismantling process more convenient and quick.

[0018] In this embodiment, the temporary guardrail is composed of a guardrail crossbar 7 and a column 6. The guardrail crossbar 7 and the column 6 are both made of round steel pipes, and the guardrail crossbar 7 and the column 6 are connected together by scaffolding fasteners.

[0019] In this embodiment, a plurality of positioning holes 5 are provided on the mounting plate 3. Specifically, the mounting plate 3 is a square plate, and positioning holes 5 are provided at the four corners of the mounting plate 3. The positioning holes 5 are fastened to the side of the stairs by bolts.

[0020] In this embodiment, the connecting rod 2 is a threaded rod, and a first nut is provided on the mounting plate 3. The other end of the connecting rod 3 extends through the support sleeve 1 and is locked with a second nut. Since the connecting rod 2 extends through the support sleeve 1, when used together, the lower end of the column 6 has a notched groove, and the connecting rod 2 is located in the notched groove, allowing the connecting rod 2 to descend to the bottom.
