Abstract
Description
Technical Field
[0001] This utility model relates to the field of building protection technology, specifically an adjustable protective railing. Background Technology
[0002] In construction sites, bridge building projects, and temporary elevated work platforms, guardrails are essential safety facilities. Guardrails typically consist of posts, crossbars, and other components, installed in a specific structural form at locations such as buildings, bridges, staircases, platforms, and openings near edges to prevent people and objects from accidentally falling or entering dangerous areas.
[0003] To address the issue of low turnover rate in traditional edge protection systems, this paper proposes a reinforcement system based on existing edge protection measures and on-site conditions. The system consists of steel pipes, toe boards, and fixing bolts. Steel pipes of different lengths are used to form an adjustable horizontal bar, which is then connected to the fixing components via bolts. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable guardrail to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable guardrail, including a stair assembly, a guardrail post fixedly connected to the top of the stair assembly, a connecting rod fixedly connected to the side of the guardrail post, a support rod fixedly connected to the inner side of the connecting rod, a telescopic adjustment rod movably connected to the outer surface of the connecting rod, an adjustment hole provided inside the connecting rod, and a fixing bolt movably connected inside the adjustment hole.
[0006] Preferably, a kick plate is fixedly connected to the side of the stair assembly.
[0007] Preferably, the telescopic adjustment rod is 60cm long and has fixing bolt holes spaced at intervals corresponding to those of the connecting rod.
[0008] Preferably, the spacing between the railing posts should not exceed 2m, and when the height of the support post is greater than 1.2m, the spacing between the connecting posts should not exceed 600mm.
[0009] Preferably, the height of the kick plate is greater than 180mm.
[0010] Preferably, the kick plate is made of 1.5mm×180mm steel plate, the railing uprights and support rods are all made of 60×60×1200mm square steel pipes, the fixing bolts are all M18 hexagonal fixing bolts, the connecting rods are made of 42mm diameter steel pipes, and the telescopic adjustment rods are made of 60mm diameter steel pipes.
[0011] Preferably, the outer surface of the connecting rod is coated with bright stripes, and a reflective strip is installed on the top of the bright stripes.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This adjustable guardrail, by installing a telescopic adjustment rod, allows the telescopic adjustment rod to move on the outer surface of the connecting rod. After aligning the telescopic adjustment rod with the adjustment hole through the internal slot, the telescopic adjustment rod is further fixed by fixing bolts, thereby completing the adjustment of the guardrail.
[0014] 2. The adjustable guardrail has bright stripes painted on the outer surface of the connecting rod, and reflective strips are installed at the top of the bright stripes, so that the connecting rod can be observed at night, thus playing a good warning role and making the position of the connecting rod clearly visible to the staff.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figures 1-2This utility model provides a technical solution: an adjustable guardrail, including a stair assembly 7. A guardrail post 1 is fixedly connected to the top of the stair assembly 7. A connecting rod 2 is fixedly connected to the side of the guardrail post 1. A support rod 3 is fixedly connected to the inner side of the connecting rod 2. A telescopic adjustment rod 4 is movably connected to the outer surface of the connecting rod 2. An adjustment hole 5 is opened inside the connecting rod 2. A fixing bolt 6 is movably connected inside the adjustment hole 5. By installing the telescopic adjustment rod 4, the telescopic adjustment rod 4 can move on the outer surface of the connecting rod 2. After aligning the internal groove of the telescopic adjustment rod 4 with the adjustment hole 5, the telescopic adjustment rod 4 is further fixed by the fixing bolt 6, thereby completing the adjustment of the guardrail.
[0020] A kick plate 8 is fixedly connected to the side of the stair assembly 7. By installing the kick plate 8, the safety of the stair assembly 7 is further improved, thereby preventing items from being placed on the stair assembly 7 and falling off from both sides.
[0021] The telescopic adjustment rod 4 is 60cm long and has fixed bolt holes that are spaced at intervals corresponding to the connecting rod 2. This increases the telescopicity of the handrail compared to previous guardrails, allowing the edge protection to adapt to different stair lengths and improving the previous situation where the length had to be extended due to unsuitable stair lengths.
[0022] The spacing between the railing posts 1 should not exceed 2m. When the height of the support post 3 is greater than 1.2m, the spacing between the connecting posts 2 should not exceed 600mm, thereby improving the practicality of the device.
[0023] The height of the kick guard 8 is greater than 180mm, which further increases the protection range of the kick guard 8 and thus further improves the practicality of the overall device.
[0024] The kick plate 8 is made of 1.5mm×180mm steel plate, the railing upright 1 and the support rod 3 are both made of 60×60×1200mm square steel pipe, the fixing bolts 6 are all M18 hexagonal fixing bolts, the connecting rod 2 is made of 42mm diameter steel pipe, and the telescopic adjustment rod 4 is made of 60mm diameter steel pipe.
[0025] The outer surface of the connecting rod 2 is coated with bright stripes, and a reflective strip is installed on the top of the bright stripes, so that the connecting rod 2 can be observed at night, thus playing a good warning role and making the position of the connecting rod 2 clearly visible to the staff.
[0026] Working principle: After preparing the necessary tools and materials for construction, including steel pipes, bolts, nuts, hammers, electric drills, etc., further clean the dust and impurities on the original structural surface to ensure the connection of the fixing bolts is firm. At the same time, according to the design plan, measure and mark the specific position of the railing upright 1 to be installed, and fix the railing upright 1 and support rod 3 to the ground using fixing bolts 6. According to the marked position, connect the connecting rod 2 to the tie rod upright 1 and support rod 3, and fix it using fixing bolts 6. Install a steel kick plate 8 at the bottom of the railing upright 1 to improve service life. Further, the telescopic adjustment rod 4 can move on the outer surface of the connecting rod 2. After aligning the internal slot of the telescopic adjustment rod 4 with the adjustment hole 5, the telescopic adjustment rod 4 is fixed with fixing bolts 6, thereby completing the adjustment of the guardrail.
