Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a temporary standardized protective railing for stairwells. Background Technology

[0002] Temporary stairwell protection is indispensable during engineering project construction. By installing temporary guardrails, it is possible to effectively prevent people from accidentally slipping and falling from the stairwell, especially suitable for high-altitude protection in construction or unfinished areas. Temporary guardrails can demarcate dangerous areas such as stairwell openings and edges, preventing unauthorized personnel from entering and causing safety hazards. Traditional temporary stairwell guardrails are usually constructed using steel pipes and fasteners. Their disadvantages include the large amount of steel pipes and fasteners used, long construction time, low efficiency, and exposed railing members that can easily cause collision injuries to construction workers. Furthermore, the large size of the fasteners used to connect the railing to the posts makes it difficult to adjust their position for a reliable connection when the distance between the posts and railing is short. Additionally, temporary guardrails constructed with steel pipes and fasteners may not meet the width requirements of stairwell openings. Utility Model Content

[0003] The purpose of this utility model is to provide a standardized temporary protective railing for stairwells, in order to solve the problems of safety hazards such as collision injuries, low construction efficiency, and difficulty in adjusting and reliably connecting the posts and railings due to the large size of the steel pipe couplers used for temporary protective railings erected with steel pipe couplers.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a temporary standardized protective railing for stairwells, comprising two vertical columns arranged along the same straight line on the floor slabs at the upper and lower ends of the stairwell at the edge of the stairwell, at least two connecting steel pipes parallel to the inclination of the stairwell are provided on the opposite surfaces of the two columns through adjustable connectors, and a railing is installed between the two columns through each of the connecting steel pipes, and the connecting steel pipes and the railing are connected by locking components.

[0005] Furthermore, the temporary standardized protective railing for stairwells provided by this utility model includes an adjustable connector comprising a connecting nut fixedly mounted on the column and a connecting screw fixedly mounted on the connecting steel pipe. The connecting steel pipe is threadedly connected to the connecting nut via the connecting screw, and the connecting screw can extend into the column through the connecting nut. Correspondingly, the column is provided with a hole that penetrates the connecting nut.

[0006] Furthermore, the temporary standardized protective railing for stairwells provided by this utility model includes an adjustable connector comprising an internally threaded hole fixedly disposed on the column and a connecting screw fixedly disposed on the connecting steel pipe, wherein the connecting steel pipe is threadedly connected to the internally threaded hole through the connecting screw.

[0007] Furthermore, the temporary standardized protective railing for stairwells provided by this utility model includes a locking component comprising a locking nut welded to the connecting steel pipe, the locking nut being threadedly connected to a locking screw, and the locking screw passing through the connecting steel pipe and tightening or being threadedly connected to the railing.

[0008] Furthermore, in the temporary standardized protective railing for stairwells provided by this utility model, the connecting steel pipe is a round pipe, the railing is a round pipe, and the railing is located inside the connecting steel pipe.

[0009] Furthermore, in the temporary standardized protective railing for stairwells provided by this utility model, the uprights are made of square steel pipes.

[0010] Furthermore, in the temporary standardized protective railing for stairwells provided by this utility model, the uprights are mounted on the floor via a base plate, and the uprights are mounted on the floor via embedded bolts penetrating the base plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The temporary standardized protective railing for stairwells provided by this utility model has its two ends fitted onto the connecting steel pipe between two posts. By fine-tuning the fitting area between the railing and the connecting steel pipe, the adjustable connection between the railing and the posts is facilitated. This avoids the situation where the fasteners are large and the adjustment range is too large, making it difficult to adjust and install when the distance between the railing and the posts is small. Thus, it solves the problem of fine-tuning the installation of the posts and railing when the distance between them is small.

[0013] The temporary standardized protective railing for stairwells provided by this utility model has its posts installed on the floor slabs at both ends of the staircase. The connecting steel pipes are adjustable and connected to the posts via adjustable connectors, which also allows for fine-tuning of the distance between the two posts. Combined with the fine-tuning of the installation of the railing and the connecting steel pipes, it ensures that the railing is reliably connected to the posts when the length of the railing is less than the distance between the two posts, further solving the problem of fine-tuning the installation of posts and railings with small gaps.

[0014] The temporary standardized protective railing for stairwells provided by this utility model has a connecting steel pipe installed between the opposite facades of two columns. After the railing is connected to the connecting steel pipe, neither end of the railing protrudes from the columns, thus avoiding the problem of the railing's ends protruding from the columns in traditional connection methods, which could easily cause collision injuries to construction workers and avoid the safety hazard of collision injuries.

[0015] The temporary standardized protective railing for stairwells provided by this utility model has an adjustable connector threaded onto the posts. The railing is fitted into the connecting steel pipe between two posts and locked to the connecting steel pipe by a locking device. This improves the efficiency of erecting and dismantling the temporary standardized protective railing for stairwells and ensures the reliability of the connection between the railing and the posts. Compared with the method of erecting protective railings for stairwells using steel pipes and fasteners, it has the advantages of high construction efficiency and short construction period.

[0016] The temporary standardized protective railing for stairwells provided by this utility model allows the posts to be positioned as close as possible to the edge of the floor slab, occupying a small area of ​​the stairwell width. This maximizes the width range from one end of the floor slab to the other, meeting the requirements for the width of the stairwell and maximizing the passage width of the stairwell.

[0017] The temporary standardized protective railing for stairwells provided by this utility model consists of standardized components, including the posts, connecting steel pipes, railings, adjustable connectors, and locking parts. These components are reusable and have the advantages of energy saving and environmental protection. Attached Figure Description
