Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a safety guardrail for foundation pits. Background Technology

[0002] Safety guardrails for foundation pits are protective facilities installed to ensure the safety of foundation pit construction sites. Foundation pit construction involves risks such as height, depth, and slope. To prevent personnel and equipment from accidentally falling or slipping, safety guardrails need to be installed for effective protection. The installation of foundation pit safety guardrails should comply with relevant safety regulations and standards to ensure their quality and reliability. Only in this way can safety hazards be minimized.

[0003] Compared to actual use, the existing foundation pit safety guardrails have a relatively small base, which can only provide simple support and stability. When encountering external impacts or strong winds, they will collapse due to insufficient base stability. Furthermore, the foundation pit guardrails are connected to each other with bolts. If one guardrail collapses, the remaining guardrails will also collapse, thus reducing the protective function of the guardrails themselves.

[0004] Therefore, in order to solve the above problems, this application provides a safety guardrail for foundation pits.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] To address the issue of insufficient stability in the guardrail base, this application provides a safety guardrail for foundation pits.

[0007] This application provides a safety guardrail for foundation pits, comprising a base, with a base plate welded to both sides. A through hole is formed on the top surface of the base plate, and a ground anchor is slidably embedded inside the through hole. Several resistance plates are welded to the bottom of the base, and a splicing rail is welded to the top of the base. A support rod is slidably embedded inside the splicing rail, and a guardrail frame is placed at one end of the support rod. Two drop grooves are formed through the inner side of the guardrail frame, and a safety net is slidably embedded inside the inner side. Two guardrail limit knobs are engaged at the top of the safety net.

[0008] Preferably, two latches are welded sequentially from top to bottom on both sides of the support rod, and a limiting groove is formed on the outer side of one end of each latch.

[0009] Preferably, two hinge rods are welded sequentially from top to bottom at both ends of the guardrail frame.

[0010] Preferably, a pull-back handle is welded to the top of the protective net, and several toothed grooves are provided at the bottom of the protective net.

[0011] Preferably, each of the several resistance-increasing plates has a toothed opening at its bottom end, and the lowest end of the resistance-increasing plate relative to the bottom surface is lower than the lowest end of the base plate relative to the bottom surface.

[0012] Preferably, the hinge rod is slidably embedded inside the clasp, and the hinge portion of the hinge rod is fitted inside the limiting groove.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. By inserting embedded nails into the base plates welded to both ends of the base, the fixation of the base relative to the ground is increased. The toothed openings at the bottom of the friction-increasing plate welded to the bottom of the base increase the gripping force between the base and the ground. The design of the drop groove allows for selective lowering of the guardrail. The several toothed openings at the bottom of the guardrail also increase the overall grip of the guardrail, thereby increasing the ground stability of the guardrail itself. Compared with existing technologies, it has stronger grip and impact resistance. Attached Figure Description

[0020] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0021] Example 1

[0022] Reference Figures 1-4A safety guardrail for foundation pits includes a base 1, with a base plate 2 welded to both sides of the base 1. A through hole 3 is provided on the top surface of the base plate 2. To increase the stability of the base 1, a ground anchor 4 is slidably embedded inside the through hole 3. Several resistance plates 5 are welded to the bottom of the base 1. To increase the gripping force of the base 1 on the ground, a splicing rail 6 is welded to the top of the base 1. A support rod 7 is slidably embedded inside the splicing rail 6. A guardrail frame 8 is placed at one end of the support rod 7. Two drop grooves 9 are provided through the inner side of the guardrail frame 8, and a safety net 10 is slidably embedded inside. Two guardrail limiting knobs 11 are fitted at the top of the safety net 10. To limit the position of the safety net 10, the two support rods 7... Two latches 12 are welded sequentially from top to bottom on the side. To splice the guardrail mechanism, a limiting groove 13 is opened on the outer side of one end of the latch 12. Two hinge rods 14 are welded sequentially from top to bottom on both ends of the guardrail frame 8. The hinge rods 14 slide into the inside of the latches 12, and the hinge part of the hinge rods 14 is fitted into the limiting groove 13. A pull handle 15 is welded to the top of the guardrail 10. Several toothed grooves are opened at the bottom of the guardrail 10. In order to increase the grip of the guardrail, several resistance plates 5 are provided with toothed openings at their bottom ends. The lowest end of the resistance plate 5 relative to the bottom surface is lower than the lowest end of the grounding plate 2 relative to the bottom surface. This is to allow the bottom end of the resistance plate 5 to be embedded in the ground to increase the grip.

[0023] Working principle: First, the operator places two bases 1 on the ground and then slides the bottom of the support rod 7 into the splicing rail 6 welded to the top of the two bases 1. Then, the two bases 1 are placed according to the edge terrain of the pit, and the distance between the two bases 1 is equal to the length of the guardrail frame 8. After placement, the hinge rods 14 welded at both ends of the guardrail frame 8 are slid into the lugs 12 welded at both ends of the support rod 7. During this process, the angle of the two ends of the guardrail can be adjusted by the hinges connected in the middle of the hinge rods 14. After the guardrail frame 8 is inserted, the ground nail 4 is inserted into the insertion hole 3 opened at the top of the floor 2 and then hammered into the ground. Since the bottom surface of the pit is all muddy soil, the grip of the base 1 is very small and it is easily disturbed by external factors. After the intervention of the ground nail 4, the base 1 can be made more stable.

[0024] Furthermore, the resistance-increasing plate 5 welded to the bottom of the base 1 can also increase the grip of the base 1. The bottom of the resistance-increasing plate 5 has several teeth, and the lowest point of the resistance-increasing plate 5 relative to the bottom surface is lower than the lowest point of the base 1 relative to the bottom surface. Therefore, the bottom of the resistance-increasing plate 5 will be embedded in the soil, thus preventing the base 1 from swaying slightly due to strong winds. This will cause the ground anchor 4 to loosen after being blown around for a long time. When necessary, the guardrail limit knob 11 embedded at the top of the guardrail 10 can be turned into a parallel state with the guardrail 10, allowing the guardrail 10 to fall. Since the bottom of the guardrail 10 also has several teeth, the guardrail 10 can also be embedded in the ground after falling, increasing the grip of the guardrail. This design can increase the stability of the base 1 of the guardrail and make it easier to cope with interference from external factors.

[0025] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
