Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a safety warning guardrail for prefabricated construction sites. Background Technology

[0002] Safety warning barriers are important facilities for ensuring the safety of construction sites. They are mainly used to isolate dangerous areas, guide the flow of people and vehicles, and prevent unauthorized personnel from entering the construction area. With the rapid development of the construction industry, the demand for safety barriers is increasing. Traditional fixed barriers, due to their large size, heavy weight, and inconvenient installation and disassembly, can no longer meet the needs of efficiency and flexibility in modern construction. In recent years, prefabricated barriers have gradually become the mainstream choice in the market due to their convenient transportation, rapid installation, and reusability.

[0003] However, existing prefabricated safety warning guardrails have poor stability in complex environments. When encountering strong winds, they may be blown down due to insufficient wind resistance. They are also difficult to keep stable on uneven construction sites and are prone to tipping over, which affects their normal function. They cannot effectively isolate dangerous areas, guide the flow of people and vehicles, and may also pose safety hazards to personnel and facilities at the construction site. Utility Model Content

[0004] The purpose of this application is to provide a prefabricated safety warning guardrail for construction sites, which has the advantages of improving the installation stability of safety warning guardrails. It solves the problem that existing prefabricated safety warning guardrails have poor stability in complex environments. When encountering strong winds, they may be blown down due to insufficient wind resistance. They are also difficult to keep stable on uneven construction sites and are prone to tipping over, which affects their normal function. They cannot effectively isolate dangerous areas, guide the flow of people and vehicles, and may also pose safety hazards to personnel and facilities at the construction site.

[0005] This application provides a prefabricated safety warning guardrail for construction sites, employing the following technical solution: A prefabricated safety warning guardrail for construction sites includes two bases, a fixing plate, and four protective nets. Support columns are fixedly connected to the upper ends of the two bases. Two sliding grooves are mirror-distributed on both sides of each of the two support columns. Two limiting grooves are mirror-distributed inside each of the two support columns. A first rotating seat is fixedly connected to one side of each of the two support columns. Support rods are rotatably connected inside each of the two first rotating seats. Multiple adjusting holes arranged in a linear array are penetrated inside each of the two support rods. Adjusting rods are slidably arranged inside each of the two support rods. Positioning holes are penetrated inside each of the two adjusting rods. A second rotating seat is fixedly connected to the bottom end of each of the two adjusting rods. Support seats are rotatably connected inside each of the two second rotating seats. Fixing holes are opened inside each of the two support seats. Two threaded rods arranged in a mirror-distributed manner are fixedly connected to one side of each of the two fixing plates. Limiting plates are fixedly connected to both sides of each of the four protective nets. Assembly grooves are opened at the upper ends of each of the four protective nets. Assembly plates are fixedly connected to the bottom ends of each of the four protective nets.

[0006] By adopting the above technical solution, a triangular support structure is formed through the base, support columns, and adjustable support rods. The stability of the triangle structure can disperse and resist external forces, such as wind and human impact, thereby enhancing the stability of the warning barrier during use and reducing the risk of safety accidents caused by the barrier tipping over. The support rod and the adjusting rod adopt a sliding connection design, and the support rod is equipped with multiple adjustment holes, allowing the height and angle of the support rod to be flexibly adjusted according to the actual construction environment to adapt to different terrains and construction needs, improving the adaptability and versatility of the device. Through modular design, the support columns and protective nets can be transported and stored independently. When it is necessary to build a safety warning barrier, only simple assembly is required to quickly build the barrier, improving construction efficiency. At the same time, the modular design also facilitates the disassembly and recycling of the device, reducing construction costs. Limiting plates are fixedly connected to both sides of the protective net, and sliding grooves and limiting slots are opened on both sides of the support columns. The protective net can be firmly installed between the two support columns through the cooperation of the limiting plates and limiting slots, as well as the guiding effect of the sliding grooves, making it less likely to shake or fall off, thereby improving the safety of the construction site.

[0007] Preferably, the four threaded rods are arranged in pairs, each passing through the adjustment hole and slidably disposed inside the positioning hole. Each pair of the four threaded rods has a baffle slidably disposed on the outer wall of one end of each threaded rod passing through the adjustment hole, and each end of each threaded rod passing through the baffle is threadedly connected to a nut.

[0008] By adopting the above technical solution, the threaded rod passes through the adjustment hole and is slidably set inside the positioning hole. The threaded connection between the nut and the threaded rod forms a stable limiting structure, which can effectively prevent the support rod and adjustment rod from loosening when under force after adjustment, thereby ensuring the overall stability of the warning guardrail.

[0009] Preferably, four reflective strips arranged in a linear array are fixedly connected to the surfaces of the four protective nets, warning boards are fixedly connected to the surfaces of two of the protective nets, and reflective boards are fixedly connected to one side of each of the two support columns;

[0010] By adopting the above technical solution, the reflective strips fixedly connected to the surface of the protective net and the reflective plates fixedly connected to one side of the support column can reflect light at night or in low-light environments, forming eye-catching warning signs. This ensures that the warning guardrail remains clearly visible at night or in low-light conditions, effectively reminding pedestrians and vehicles to pay attention to the construction area, thereby improving the safety of nighttime construction. The warning plates fixedly connected to the surface of the protective net can be printed or pasted with various warning slogans, patterns, or symbols to convey specific safety information or warnings, further enhancing the warning effect.

[0011] Preferably, a warning light is fixedly connected to the upper end of one side of each of the two support columns;

[0012] By adopting the above technical solution, the warning light actively emits light and flashes, forming an effective warning under low light conditions such as night, fog, and rain, ensuring that the warning information is clearly visible under all weather conditions, and significantly reducing the risk of safety accidents caused by poor visibility.

[0013] Preferably, two reinforcing ribs arranged in a mirror image are fixedly connected between the two sides of the support columns and the upper end of the base;

[0014] By adopting the above technical solution, the reinforcing ribs are used to strengthen the connection between the support column and the base, which can resist external loads and reduce the risk of the guardrail tipping over.

[0015] Preferably, each of the two support columns has four threaded holes arranged in a rectangular array at its upper end, and each of the two support columns has an upper cover. Each of the two upper covers has four through holes arranged in a rectangular array inside, and each of the through holes has a fixing bolt slidably disposed inside. One end of each of the fixing bolts passing through the through hole is threaded inside the threaded hole.

[0016] By adopting the above technical solution, the top cover directly prevents the protective net from sliding out of the chute by covering the upper end of the support column. During installation, after sliding the protective net into the chute, the top cover is put on and the bolts are tightened to complete the fixation. The operation is simple and efficient.

[0017] Preferably, the four protective nets are slidably disposed inside two sliding grooves on both sides, and the multiple limiting plates are slidably disposed inside the limiting grooves;

[0018] By adopting the above technical solution, the protective net is embedded in the sliding grooves on both sides to form a constraint. The cooperation between the limiting plate and the limiting groove further restricts the displacement of the protective net. The protective net is inserted by sliding through the sliding groove, which is convenient for installation. When disassembling, the protective net only needs to be slid out of the sliding groove, which is convenient for replacement.

[0019] Preferably, all four assembly plates are slidably disposed inside the assembly slot;

[0020] By adopting the above technical solution, the assembly plate is slidably inserted into the assembly slot, thereby forming a connection between multiple protective nets and improving the connection stability of multiple protective nets.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] This prefabricated safety warning fence for construction sites enhances the safety and practicality of construction sites through its base, support columns, adjustable support rods, protective netting, and modular connection structure. The base and support columns form a stable foundation, while the adjustable support rods create a triangular support structure that adapts to different terrains and construction needs. This enhances the fence's wind and collision resistance, reducing the risk of tipping over. The protective netting, with its limiting plates and grooved support columns, ensures a stable installation, preventing wobbling or detachment. It also facilitates quick installation and disassembly, improving construction efficiency. Furthermore, the protective netting surface is equipped with reflective strips and warning panels, and the support columns... A reflector is installed on one side, and a warning light is added to the upper end of the support column, forming multiple warning signs to ensure clear visibility at night or in low light conditions, thus improving the safety of nighttime construction. The modular design allows components such as support columns and protective nets to be transported, stored, and reused independently, reducing construction costs. The top cover is connected to the upper end of the support column by fixing bolts to further prevent the protective net from slipping out and ensure the overall stability of the structure. The assembly plate is slidably set inside the assembly groove, enhancing the connection stability between multiple protective nets. Through structural optimization and modular design, this guardrail achieves the advantages of efficient installation and stable protection, providing reliable safety for the construction site.

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0031] Example 1: A prefabricated safety warning railing for construction sites includes two bases 1, a fixing plate 13, and four protective nets 17. Support columns 2 are fixedly connected to the upper ends of both bases 1, providing installation positions for the protective nets 17. Two mirror-distributed sliding grooves 3 are provided on both sides of each support column 2, and two mirror-distributed limiting grooves 4 are provided inside each support column 2. A first rotating seat 5 is fixedly connected to one side of each support column 2, and a support rod 6 is rotatably connected inside each of the two first rotating seats 5. The support rod 6 allows for angle adjustment during installation via the rotating seats. The triangular support structure, through its structural stability, can disperse and resist external forces such as wind and human impact, thereby enhancing the stability of the warning railing during use and reducing the risk of safety accidents caused by railing collapse. Each of the two support rods 6 has multiple adjustment holes 7 arranged in a linear array inside. Each of the two support rods 6 also has a sliding adjustment rod 8 inside, and each of the two adjustment rods 8 has a positioning hole 9 inside. The support rods and adjustment rods 8 are connected by a sliding connection design, and the multiple adjustment holes 7 on the support rods 6 allow for flexible adjustment of the height and angle of the support rods 6 according to the actual construction environment. The device is designed to adapt to different terrains and construction needs, improving its adaptability and versatility. Two adjusting rods 8 are fixedly connected to their bottom ends with second rotating seats 10. Each of the two second rotating seats 10 has a support seat 11 rotatably connected inside. The support seats 11 are used to support the ground. Each of the two support seats 11 has a fixing hole 12 inside, into which ground nails can be driven to further enhance the installation stability of the device. Two threaded rods 14 are fixedly connected to one side of each of the two fixing plates 13, arranged in a mirror image. Limit plates 18 are fixedly connected to both sides of each of the four protective nets 17. Each of the four protective nets 17 has an assembly groove 19 at its upper end. The bottom of the protective net 17 is fixedly connected to an assembly plate 20. Four threaded rods 14 are arranged in pairs, passing through the adjustment hole 7 and slidingly positioned inside the positioning hole 9. Baffles 15 are slidably installed on the outer wall of each pair of the four threaded rods 14 passing through the adjustment hole 7. Nuts 16 are threadedly connected to the end of each of the four threaded rods 14 passing through the baffles 15. The threaded rods 14 pass through the adjustment hole 7 and slide inside the positioning hole 9. The threaded connection between the nuts 16 and the threaded rods 14 forms a stable limiting structure, which can effectively prevent the support rod 6 and the adjustment rod 8 from loosening when under force after adjustment, thereby ensuring the overall stability of the warning guardrail.

[0032] Example 2: A prefabricated safety warning fence for construction sites. Four reflective strips 21 arranged in a linear array are fixedly connected to the surfaces of four protective nets 17. Warning panels 22 are fixedly connected to the surfaces of two protective nets 17. Reflective panels 23 are fixedly connected to one side of each of the two support posts 2. The arrangement of the reflective strips 21 fixedly connected to the surfaces of the protective nets 17 and the reflective panels 23 fixedly connected to one side of the support posts 2 allows for light reflection at night or in low-light conditions, forming conspicuous warning signs. This ensures the warning fence remains clearly visible at night or in low-light conditions, effectively reminding pedestrians and vehicles to pay attention to the construction area, thereby improving safety during nighttime construction. The warning board 22, fixedly connected to the surface of the protective net 17, can be printed or pasted with various warning slogans, patterns, or symbols to convey specific safety information or warnings, further enhancing the warning effect. Warning lights 24 are fixedly connected to the upper ends of one side of each of the two support columns 2. These lights 24 actively emit light and flash, creating an effective warning under low-light conditions such as nighttime, foggy days, and rainy days, ensuring that the warning information is clearly visible in all weather conditions and significantly reducing the risk of safety accidents caused by poor visibility. Two mirror-distributed reinforcing ribs 25 are fixedly connected between the two sides of the support columns 2 and the upper end of the base 1. These reinforcing ribs 25 are used to strengthen the support columns 2 and... The connection strength between the bases 1 can resist external loads and reduce the risk of the guardrail tipping over. Each of the two support columns 2 has four threaded holes 26 arranged in a rectangular array at its upper end. Each of the two support columns 2 has a top cover 27, and each of the top covers 27 has four through holes 28 arranged in a rectangular array inside. Fixing bolts 29 are slidably installed inside the through holes 28, and one end of each fixing bolt 29 is threaded into the threaded hole 26. The top cover 27, by covering the upper end of the support columns 2, directly prevents the protective net 17 from sliding out of the groove 3. During installation, after sliding the protective net 17 into the groove 3, the top cover 27 is placed on and the bolts are tightened. It can be fixed and is simple and efficient to operate. The four protective nets 17 are slidably set inside the two slide grooves 3 on both sides. Multiple limiting plates 18 are slidably set inside the limiting grooves 4. The protective nets 17 are embedded in the slide grooves 3 on both sides to form a constraint. The cooperation between the limiting plates 18 and the limiting grooves 4 further restricts the displacement of the protective nets 17. The protective nets 17 are slidably inserted through the slide grooves 3 for easy installation. When disassembling, the protective nets 17 only need to be slid out of the slide grooves 3 for easy replacement. The four assembly plates 20 are slidably set inside the assembly grooves 19. The assembly plates 20 are slidably inserted into the assembly grooves 19 to form a connection between the multiple protective nets 17, thereby improving the connection stability of the multiple protective nets 17.

[0033] The implementation principle of this application embodiment is as follows:

[0034] The support column 2 and the base 1 form the main support structure. The protective net 17 can be quickly installed and disassembled through the sliding groove 3 and the limiting groove 4. The top cover 27 is fixed with bolts to prevent the protective net 17 from falling off. The height can be adjusted by the combination of the support rod 6, the adjusting rod 8 and the support seat 11, and the adjusting hole 7 and the positioning hole 9. The threaded rod 14 is inserted into the positioning hole 9 and fixed by the baffle 15 and the nut 16 to prevent the support rod 6 and the adjusting rod 8 from loosening under force after adjustment. The support rod 6 can be rotated by the rotating seat to adjust the angle, forming a stable triangular support structure. The four protective nets 17 are connected to each other by the assembly plate 20 and the assembly groove 19 to enhance the overall integrity. The reflective strip 21, the reflective plate 23 and the warning light 24 form an all-weather warning to ensure visibility under different lighting conditions. The reinforcing rib 25 improves the connection strength between the support column 2 and the base 1. The fixing hole 12 can be used to install ground nails to enhance the fixation to the ground. Through modular assembly, adjustable support and the synergistic effect of multiple warnings, the installation is convenient and the site adaptability is guaranteed, and a reliable protective effect is provided.
