Description

Technical Field

[0001] This utility model belongs to the technical field of construction site fences and guardrails, and specifically relates to a construction site fence and guardrail structure. Background Technology

[0002] In the construction industry, fence structures are important facilities for ensuring the safety of construction sites and isolating construction areas from the external environment. They can not only prevent unauthorized personnel from entering the construction site and avoid safety accidents, but also effectively block the impact of dust and noise during construction on the surrounding environment. At the same time, they play a certain warning role and guide pedestrians and vehicles to pass through reasonably.

[0003] Traditional construction site fencing structures typically consist of base posts and guardrail panels, usually connected by bolts. During assembly, workers must use tools to tighten each bolt individually, a cumbersome process that consumes significant time and manpower. This inefficient assembly method is particularly problematic on large construction sites where numerous fencing sections need to be installed, as it significantly prolongs the construction period and increases costs. Furthermore, the connecting components of traditional fencing structures are mostly exposed to the external environment, making them susceptible to accidental contact and damage, thus increasing maintenance costs. Therefore, this invention proposes a new construction site fencing structure. Utility Model Content

[0004] The purpose of this utility model is to provide a construction site fence structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a construction site fence structure, comprising multiple base columns, guardrail panels installed on both sides of the base columns, and a support base pad fixed to the bottom of the base columns, and further comprising...

[0006] The base column has two U-shaped connectors that are adapted to the guardrail plate on both sides, and the edge of the guardrail plate is embedded into the inside of the U-shaped connector.

[0007] The inner limiting mechanism is provided on the inner side of the base column, including an inner base rod fixed to the inner surface of the base column, an inner rotating plate movably sleeved on the surface of the inner base rod, an end plate fixed to the rear end of the inner base rod, and a spring sleeved on the surface of the inner base rod and located between the inner rotating plate and the end plate. The two ends of the inner rotating plate extend to the inner side of the two guardrail plates respectively. Limiting rods are fixed on the surface of both ends of the inner rotating plate, and the surface of the guardrail plate is provided with limiting holes corresponding to the limiting rods. The end of the limiting rod is inserted into the limiting hole.

[0008] Preferably, the inner limiting mechanism further includes two inner notches formed on the inner surface of the base column, and the positions of the two inner notches correspond to the limiting lever.

[0009] Preferably, a circular sleeve hole corresponding to the inner base rod is provided through the center of the inner rotating plate.

[0010] Preferably, one end of the spring abuts against the surface of the inner rotating plate, and the other end of the spring abuts against the surface of the end plate.

[0011] Preferably, it also includes a base, wherein a supporting pad is installed on the top surface of the base relative to both sides of the base column, and the bottom end of the guardrail rests on the top surface of the supporting pad.

[0012] Preferably, the top surface of the base has an installation groove on both sides of the base column, and the support pad is embedded in the installation groove.

[0013] Preferably, the bottom surface of the support pad is provided with an integrated socket, and the inner wall of the bottom end of the mounting groove is provided with a socket for insertion.

[0014] Preferably, both sides of the socket are provided with integrated side locking blocks, and both sides of the inner wall of the socket are provided with side locking grooves corresponding to the side locking blocks, and the side locking blocks are squeezed into the side locking grooves.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model proposes a construction site fence structure. By designing an inner limiting mechanism between the base column and the guardrail panel, and cooperating with a U-shaped connecting seat, the assembly convenience between the base column and the guardrail panel can be greatly improved. Construction workers only need to place the guardrail panel in the corresponding position of the base column, and the assembly can be quickly completed through the cooperation of the inner limiting mechanism and the U-shaped connecting seat. No complicated tools and operating procedures are required, which greatly shortens the construction cycle and reduces construction costs. At the same time, it can ensure the stability after assembly. Moreover, since the inner limiting mechanism is located inside the entire guardrail structure during use, it cannot be touched by outsiders and can only be touched by construction workers inside the guardrail structure. This avoids damage to the connecting parts by outsiders, improves the stability and safety of the guardrail structure, and solves the problem of low assembly convenience of traditional guardrail structures.

[0023] 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.

[0024] Example 1

[0025] Please see Figures 1 to 5 This is the first embodiment of the present utility model, which provides a technical solution: a construction site fence structure, including multiple base columns 1, guardrail panels 2 installed on both sides of the base columns 1, and support pads 4 welded and fixed to the bottom of the base columns 1, and also includes...

[0026] U-shaped connecting seat 11, two U-shaped connecting seats 11 adapted to guardrail 2 are welded and fixed on both sides of the base column 1, and the edge of guardrail 2 is embedded into the inner side of U-shaped connecting seat 11. U-shaped connecting seat 11 can limit guardrail 2 in the horizontal direction, so that guardrail 2 can only move up and down for disassembly and assembly.

[0027] The inner limiting mechanism 5, located inside the base column 1, includes an inner base rod 54 welded and fixed to the inner surface of the base column 1, an inner rotating plate 51 movably sleeved on the surface of the inner base rod 54, an end plate 56 fixed to the rear end of the inner base rod 54, and a spring 55 sleeved on the surface of the inner base rod 54 and located between the inner rotating plate 51 and the end plate 56. Both ends of the inner rotating plate 51 extend to the inner sides of the two guardrail panels 2. Limiting rods 52 are welded and fixed to both ends of the inner rotating plate 51. Limiting holes 53 corresponding to the limiting rods 52 are provided through the surface of the guardrail panels 2. The end of the limiting rod 52 is inserted into the limiting hole 53, which can stably limit the vertical movement of the guardrail panels 2. This, in conjunction with the U-shaped connecting seat 11, enables the rapid and stable installation of the guardrail panels 2. During actual installation and disassembly, only the construction personnel inside the guardrail structure need to remove the inner rotating plate from the inside of the base column 1. Pulling plate 51 gradually compresses spring 55, causing limit lever 52 to move out of limit hole 53, thus no longer limiting guardrail plate 2. At this time, rotating inner rotating plate 51 rotates on the surface of inner base rod 54, allowing limit lever 52 to rotate into inner notch 57, thus no longer obstructing guardrail plate 2. Lifting or lowering guardrail plate 2 allows it to separate from or engage with U-shaped connecting seat 11, enabling quick assembly and disassembly of base post 1. This solves the problem of low assembly efficiency in traditional guardrail structures. Furthermore, since the inner limiting mechanism 5 is located inside base post 1, which is the inner side of the entire guardrail structure, it cannot be accessed by outsiders. It can only be accessed by construction workers inside the guardrail structure, thus preventing damage to the inner limiting mechanism 5 by outsiders and ensuring assembly stability.

[0028] In this embodiment, preferably, the inner limiting mechanism 5 further includes two inner notches 57 formed on the inner surface of the base column 1, and the positions of the two inner notches 57 correspond to the limiting rod 52, so that after the limiting rod 52 is pulled out of the limiting hole 53, the inner rotating plate 51 can be rotated, causing the limiting rod 52 to be screwed into the inner notch 57, so that the limiting rod 52 no longer obstructs the guardrail 2, making it convenient for operators to disassemble and maintain the guardrail 2.

[0029] In this embodiment, preferably, a circular sleeve hole corresponding to the inner base rod 54 is provided through the center of the inner rotating plate 51, so that the inner rotating plate 51 can slide and rotate smoothly on the surface of the inner base rod 54.

[0030] In this embodiment, preferably, one end of the spring 55 abuts against the surface of the inner rotating plate 51, and the other end of the spring 55 abuts against the surface of the end plate 56. Under the pushing of the spring 55, the limiting rod 52 can be stably locked in the limiting hole 53 during daily use, ensuring the limiting stability of the guardrail plate 2, thereby ensuring the installation stability of the entire guardrail structure.

[0031] Example 2

[0032] Please see Figures 1 to 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that a support pad 4 is installed on both sides of the top surface of the base 3 relative to the base column 1, and the bottom end of the guardrail 2 rests on the top surface of the support pad 4. The bottom of the guardrail 2 can be effectively supported by the support pad 4.

[0033] In this embodiment, preferably, it also includes a base 3. The top surface of the base 3 has an installation groove 31 on both sides of the base column 1. The support pad 4 is embedded in the installation groove 31. The bottom surface of the support pad 4 has an integrated socket 41. The inner wall of the bottom end of the installation groove 31 has a socket hole 32 for the socket 41 to be inserted. The two sides of the socket 41 have integrated side locking blocks 42. Both are made of rubber and will undergo elastic deformation when squeezed. The inner walls of both sides of the socket hole 32 have side locking grooves 33 corresponding to the side locking blocks 42. The side locking blocks 42 are squeezed into the side locking grooves 33, which can effectively limit the socket 41 and the support pad 4, and ensure the installation stability of the support pad 4.

[0034] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
