Description

Technical Field

[0001] This utility model relates to the field of construction protection facilities technology, and in particular to a foldable construction safety guardrail. Background Technology

[0002] Safety barriers are essential facilities in construction, used to isolate hazardous areas and prevent personnel and materials from falling. Traditional barriers are typically assembled using welding or bolting, resulting in problems such as large size, inconvenient transportation, low assembly / disassembly efficiency, and large storage space requirements. Especially for construction sites requiring frequent movement and relocation, the handling and redeployment of traditional barriers is time-consuming and labor-intensive, impacting construction efficiency. While some foldable or detachable barrier designs exist, they still have shortcomings in structural stability, ease of assembly / disassembly, component storage and management, and adaptability to different ground conditions. For example, some folding structures are complex and lack stability when unfolded; disassembled components are scattered, easily lost, and inconvenient to transport; and the support structure is difficult to adjust or has unsatisfactory fixing effects. Therefore, there is an urgent need for a new type of construction safety barrier that is structurally stable and reliable, easy and quick to assemble and disassemble, allows for centralized storage and transport of all moving parts, provides stable support, and is highly adaptable. Utility Model Content

[0003] This utility model relates to a foldable construction safety guardrail. Through the synergistic effect of the base box, connecting corner brackets, pins, guardrail panels, support rods, insertion holes, limiting corner brackets, supporting legs, anti-slip pads, handles, cover plates, and grid holes and crossbeams, it not only achieves the core functions of rapid installation and stable protection, but also perfectly solves the pain points of traditional guardrails being difficult to transport and occupying a lot of space through the design of being detachable and stored in the base box. This greatly improves the deployment efficiency and turnover convenience of construction safety protection equipment.

[0004] In a first aspect, this utility model provides a foldable construction safety guardrail, specifically comprising: a base box; the base box is a cuboid box structure, with connecting corner brackets fixedly provided at the upper and lower ends of the front ends of the left and right side walls of the base box, and guardrail plates installed between the upper and lower connecting corner brackets on the same side via pins, the guardrail plates being perpendicular to the base box; support rods for support are provided between the middle of the rear ends of the left and right side walls of the base box and the guardrail plates on the corresponding sides; limiting corner brackets are provided at the left and right corners of the bottom rear end of the base box, and supporting legs are installed in the limiting corner brackets via pins.

[0005] Optionally, handles are vertically provided at the upper ends of the left and right side walls of the base box.

[0006] Optionally, the base box has a hollow interior and an opening at the top. A cover plate is installed at the opening via a hinge. The end of the cover plate away from the hinge extends out of the base box and has a smooth structure. The disassembled guardrail, struts, and support legs are stored in the interior of the base box.

[0007] Optionally, the connecting corner bracket is provided with two pin holes for inserting pins, and the distribution direction of the two pin holes is consistent with the installation direction of the guardrail.

[0008] Optionally, one side of the limiting angle seat is a closed end, and when the support leg is inserted into the limiting angle seat, it forms a fixed angle of 45 degrees with the base box. The end of the support leg is provided with a rubber anti-slip pad.

[0009] Optionally, insertion holes are provided at the installation positions of the support rods on the left and right side walls of the base box, and one end of the support rod is inserted into the insertion hole.

[0010] Optionally, the guardrail has vertically spaced evenly spaced grid holes, and the other end of the support rod is inserted into the grid hole near the outer center, and a crossbeam is provided in the grid hole to support the support rod.

[0011] This utility model provides a foldable safety guardrail for construction, which has the following advantages:

[0012] The foldable construction safety guardrail proposed in this utility model effectively overcomes the shortcomings of existing technologies and achieves significant beneficial effects through its ingenious structural design. Firstly, the core base box serves as a load-bearing base and integrated storage center. Its rectangular box-shaped structure ensures overall stability. The internal cavity design, combined with a hinged cover plate with smooth extended ends, allows the disassembled guardrail panels, support rods, and support legs to be safely and centrally stored within the base box cavity. The smooth structure of the cover plate prevents bumps and scratches during handling. The vertically positioned handles on both sides of the upper end of the base box greatly facilitate workers' gripping and handling of the entire device or the empty base box, significantly improving the portability and on-site turnover efficiency of the device and solving the problems of scattered and easily lost components and inconvenient transportation. Secondly, regarding the rapid assembly and disassembly of the protective structure, the connecting corner brackets at the upper and lower ends of the front side wall of the base box cooperate with the pins to achieve rapid and secure installation and disassembly of the guardrail. The design that the distribution direction of the two pin holes on the connecting corner brackets is consistent with the installation direction of the guardrail ensures that the pins can effectively restrain the swaying of the guardrail, making it firmly and perpendicular to the base box to form a reliable protective barrier. Furthermore, the stability of the device is ensured by multiple measures: one end of the support rod is inserted into the insertion hole on the side wall of the base box, and the other end can be selectively inserted into the outer grid hole in the middle of the guardrail in Embodiment 2. The crossbeam set in the grid hole provides stable support, forming an effective diagonal support force, which significantly enhances the guardrail's anti-tipping ability. At the same time, the support leg rod installed by the bottom limiting angle seat at the rear of the base box through the pin is able to maintain an optimal fixed angle of about 45 degrees with the base box under the design constraint of the closed end on one side of the limiting angle seat. The anti-slip pad equipped at its end effectively increases the friction with the ground. The dual support structure (support rod and support leg rod) works together to ensure the stable placement of the device under various ground conditions and prevent sliding and overturning. In addition, the vertically uniform grid holes opened on the guardrail in Embodiment 2 not only help to reduce the overall weight and material cost, but more importantly, they provide multiple optional connection points (grid holes) for the support rod. Combined with the support of the crossbeam, the support angle can be finely adjusted and optimized according to the actual site conditions, further improving the adaptability and practicality of the device. In summary, this utility model integrates stable protection, quick assembly and disassembly, centralized storage of components, convenient handling, multiple stable supports, and good adaptability, effectively improving the efficiency and reliability of construction safety protection work.

[0021] Please refer to Figures 1 to 3 :

[0022] Example 1: This utility model proposes a foldable construction safety guardrail, including: a base box 1; the base box 1 is a rectangular box structure, with connecting corner seats 103 fixedly installed at the upper and lower ends of the front ends of the left and right side walls of the base box 1, and guardrail plates 2 installed between the upper and lower connecting corner seats 103 on the same side through pins 104, the guardrail plates 2 being perpendicular to the base box 1; support rods 3 are respectively provided between the middle of the rear end of the left and right side walls of the base box 1 and the guardrail plates 2 on the corresponding side; limiting corner seats 105 are respectively provided at the left and right corners of the bottom rear end of the base box 1, and supporting legs 4 are installed in the limiting corner seats 105 through pins 104.

[0023] Among them, handles 101 are vertically provided at the upper ends of the left and right side walls of the base box 1.

[0024] The base box 1 has a hollow interior and an opening at the top. A cover plate 102 is installed at the opening via a hinge. The end of the cover plate 102 away from the hinge extends out of the base box 1 and has a smooth structure. The disassembled guardrail 2, support rod 3, and support leg 4 are stored in the interior of the base box 1.

[0025] The connecting corner bracket 103 is provided with two pin holes for the insertion of the pin 104, and the distribution direction of the two pin holes is consistent with the installation direction of the guardrail plate 2.

[0026] One side of the limiting angle seat 105 is a closed end. When the support leg 4 is inserted into the limiting angle seat 105, it forms a fixed angle of 45 degrees with the base box 1. The end of the support leg 4 is provided with a rubber anti-slip pad 401.

[0027] Among them, the mounting positions of the support rods 3 on the left and right side walls of the base box 1 are provided with insertion holes 106, and one end of the support rod 3 is inserted into the insertion hole 106.

[0028] In Embodiment 2, based on Embodiment 1, the guardrail 2 has vertically spaced evenly spaced grid holes 201, and the other end of the support rod 3 is inserted into the grid hole 201 in the middle and outward, and a crossbeam 202 is provided in the grid hole 201 to support the support rod 3.

[0029] Working principle:

[0030] The foldable construction safety guardrail proposed in this utility model has a core structure, the base box 1, which serves as the load-bearing base and storage center of the entire device. Its rectangular box-shaped structure provides a stable foundation. The connecting corner brackets 103 at the front ends of the left and right side walls of the base box 1, together with the pins 104, enable the quick and secure installation and disassembly of the guardrail panels 2, allowing the guardrail panels 2 to stand vertically against the base box 1 to form the main protective barrier. To enhance the anti-tipping ability of the guardrail panels 2 in the unfolded state, a support rod 3 is installed between the middle of the rear end of the base box 1 side wall and the corresponding guardrail panel 2. This support rod 3 is inserted into the insertion hole 106 on the side wall of the base box 1, forming an effective diagonal support force. To further ensure overall stability, the limiting corner brackets 105 at the bottom left and right corners of the rear end of the base box 1 are equipped with support legs 4 via pins 104. Their special design ensures that the support legs 4 maintain a fixed angle of approximately 45 degrees with the base box 1, and the anti-slip pads 401 at the ends of the support legs 4 effectively increase the friction with the ground, preventing the device from sliding.

[0031] In terms of portability, the handle 101 on the upper end of the base box 1 greatly facilitates workers' gripping and handling of the entire device or just the base box 1. The base box 1 is designed as a hollow structure, and a cover plate 102 is installed at its upper opening via a hinge. The smooth structure of the cover plate 102 away from the hinge end avoids bumps and scratches during handling or operation. Opening the cover plate 102 allows the disassembled guardrail 2, support rod 3, and support leg 4 to be completely stored in the inner cavity of the base box 1, realizing centralized storage and transportation of all moving parts, significantly improving the portability of the device and the efficiency of on-site management. The design of the distribution direction of the two pin holes on the connecting corner seat 103 being consistent with the installation direction of the guardrail 2 ensures that the pin 104 can effectively restrain the freedom of the guardrail 2 in the installed state, preventing it from shaking or falling off.

[0032] In Embodiment 2, the vertically uniform grid holes 201 opened in the guardrail plate 2 reduce the overall weight and lower the material cost. The end of the support rod 3 away from the base box 1 can be selectively inserted into a certain grid hole 201 in the middle of the guardrail plate 2. The crossbeam 202 set in the specific grid hole 201 provides a stable support surface for the support rod 3, ensuring a reliable connection between the support rod 3 and the guardrail plate 2 and effectively transmitting the supporting force.
