Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically a prefabricated guardrail that integrates safety rope hanging points and edge protection. Background Technology

[0002] In construction projects, bridge construction, and high-altitude operations, edge protection is a key measure to ensure the safety of workers. Guardrails prevent people or objects from falling from the edges of buildings, the perimeter of foundation pits, and the edges of platforms, thereby protecting the personal safety of construction workers.

[0003] Existing edge guardrails only have basic protective functions and cannot integrate safety rope attachment points. When workers carry out high-altitude or mobile work around the guardrails, they need to find or set up additional safety rope attachment points, such as welding temporary hanging ears or fixing independent hanging frames, which increases construction costs. If the safety rope is directly suspended from the guardrail, the safety rope attachment point is fixed and cannot move with the movement of the construction workers, thus restricting their movement.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the prefabricated guardrail that integrates safety rope attachment points and edge protection:

[0019] 1. This device is equipped with a guardrail unit structure consisting of a horizontal bar, a first post, and a second post, which prevents people or objects from falling from the edge, thus achieving edge protection in construction projects. The length of the protection can be flexibly adjusted by assembling and connecting the guardrail unit structures. The horizontal bar has a groove inside, and the hook structure in the groove can be directly used to connect the safety rope. There is no need to find additional hanging points during construction operations. The installation ring inside the hook structure can slide, and the hanging point position can be flexibly adjusted according to the working position.

[0029] 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.

[0030] Please see Figures 1-6 This utility model provides a technical solution: a prefabricated guardrail that integrates safety rope hanging points and edge protection, including a horizontal bar 1, a first post 2, a second post 3, a sliding groove 4, an inner slider 5, an outer slider 6, a mounting post 7, a mounting ring 8, a first positioning block 9, and a second positioning block 10.

[0031] The horizontal bar 1 is a cylindrical structure. Its outer surface is fitted with a first post 2 and a second post 3. The surfaces of each post have semi-circular grooves. The rear surface of the horizontal bar 1 is fixedly connected to the inner wall of the groove on the surface of the first post 2, and the front surface of the horizontal bar 1 is fixedly connected to the inner wall of the groove on the surface of the second post 3. The horizontal bar 1, first post 2, and second post 3 constitute a guardrail unit structure. There are two second posts 3, symmetrically arranged about the first post 2. The first and second posts 2 are arranged in opposite directions on the surface of the horizontal bar 1. A butt-joint assembly structure is provided between the guardrail unit structures. The docking assembly structure achieves the assembly connection between different crossbars 1 through positioning block 9 and positioning block 10. The docking assembly structure includes positioning block 9, which is a cylindrical structure with one open side. The end of positioning block 9 away from the open side is fixedly installed on one end of the crossbar 1, and positioning block 10 is fixedly installed on the other end of the crossbar 1. Positioning block 10 is a cylinder, and the outer diameter of positioning block 10 is the same as the inner diameter of positioning block 9. Positioning block 9 and positioning block 10 are respectively provided with two sets of vertical circular through holes on their surfaces, and the circular through holes on the surfaces of positioning block 9 and positioning block 10 are aligned and matched.

[0032] like Figure 1 and Figure 2As shown, based on the actual needs of the construction site, the guardrail unit structure is flexibly assembled and combined. The second positioning block 10 at one end of the first guardrail unit structure's horizontal bar 1 is aligned with the first positioning block 9 at one end of the second horizontal bar 1. The second positioning block 10 is inserted into the open end of the first positioning block 9 until the two sets of vertical circular through holes on the surface of the first positioning block 9 are completely aligned with the corresponding through holes on the surface of the second positioning block 10. The threaded rod is inserted into the aligned through holes and fixed with nuts, thus completing the docking assembly between the two guardrail unit structures. Grounding bolts are used to connect and fix the first post 2 and the second post 3 to the ground, thereby realizing the installation and assembly process of the guardrail unit structure. According to actual needs, different numbers of guardrail unit structures can be selected for assembly and fixing.

[0033] The crossbar 1 has a groove 4 inside, which is a cylindrical structure. One side of the groove 4 is connected to the front surface of the crossbar 1. The groove 4 has a hook structure inside, which connects and supports the safety rope through the mounting ring 8. The hook structure includes an inner slider 5, which is a ring structure and is slidably installed on the inner wall of the groove 4. An outer slider 6 is provided on the outer surface of the inner slider 5, which is also a ring structure and is slidably installed on the outer surface of the crossbar 1. One inner slider 5 and one outer slider 6 are connected to the same mounting post 7. The mounting post 7 extends from the end where the groove 4 is connected to the front surface of the crossbar 1. One end of the mounting post 7 is rotatably connected to the inner slider 5 and the outer slider 6 respectively. The other end of the mounting post 7 is rotatably installed with a mounting ring 8, which is a ring.

[0034] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, when construction workers are working, they can hook the safety rope hook into the circular mounting ring 8. The mounting ring 8 is rotatably connected to the mounting post 7, and the mounting post 7 is simultaneously rotatably mounted on the surfaces of the inner slider 5 and the outer slider 6. Therefore, during actual operation, the safety rope hook can adjust its angle as the worker moves, preventing the safety rope from being stretched due to a fixed angle. At the same time, the inner slider 5 is slidably mounted inside the slide groove 4, and the outer slider 6 is slidably mounted on the outer surface of the crossbar 1. When working near the edge, the worker can push the outer slider 6 according to their own range of movement, causing the inner slider 5 to slide along the slide groove 4, thereby adjusting the position of the mounting ring 8 and the safety rope. During the sliding process, the inner slider 5 and the outer slider 6 form a double limit, ensuring that the mounting post 7 does not detach from the crossbar 1, and the mounting ring 8 always moves along the axis of the crossbar 1, increasing the safety performance of the safety rope.

[0035] Working Principle: When using this prefabricated guardrail with integrated safety rope attachment points and edge protection, the guardrail unit structure, consisting of horizontal bar 1, post 2, and post 3, forms the main edge protection structure, preventing personnel or objects from falling during construction. The safety rope is connected to the installation ring 8. During operation, the installation ring 8 and installation post 7 slide synchronously with the outer slider 6 and inner slider 5, flexibly adjusting the attachment point position of the safety rope. The installation post 7 and installation ring 8 are rotatable to accommodate different tension angles of the safety rope. Multiple guardrail unit structures are connected by positioning block 9 and positioning block 10. Positioning block 10 is inserted into positioning block 9, and after the through holes are aligned, bolts are used for fixing, thereby flexibly adjusting the assembly length of the guardrail unit structure and increasing the overall practicality.
