Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, and in particular to a temporary guardrail device for municipal construction. Background Technology

[0002] When municipal buildings are under construction, protective fences are usually installed on the outside of the construction area to prevent unauthorized personnel from entering the construction area and causing damage or affecting the construction, and also to prevent unauthorized personnel from entering the construction area and causing danger.

[0003] In existing technologies, traditional guardrails suffer from a lack of structural flexibility, making angle adjustments between adjacent guardrails extremely difficult and hindering their ability to closely conform to complex and varied terrain. This significantly compromises the tightness and integrity of the protection. While existing interlocking guardrails offer some convenience in angle adjustment and can adapt to terrain to a certain extent, their structural stability is relatively insufficient. They are prone to deformation or even damage when subjected to external impacts or disturbances, further diminishing their protective effect and failing to provide reliable safety guarantees for construction areas.

[0004] To address this issue, we propose a temporary guardrail device for municipal construction to solve the problems of existing guardrails being difficult to fit tightly in complex terrain and having weak protective performance. Utility Model Content

[0037] like Figure 1-5 As shown, this utility model provides a temporary guardrail device for municipal construction, including: posts 1, two guardrail panels 2, and a corner fixing component 3. The number of posts 1 and guardrail panels 2 can be adjusted according to the actual needs of the construction site.

[0038] The two sides of the upright 1 are rotatably connected to the two railing panels 2. The upright 1 supports the railing panels 2, and the railing panels 2 can rotate around the upright 1, which makes it convenient to adjust the angle according to the terrain of the area edge.

[0039] The fixed-angle assembly 3 includes two rotating rings 30 located at the middle of the upper end of the column 1. Each rotating ring 30 has a threaded sleeve 31 connected to its side wall. A screw 32 is connected to the middle of the threaded sleeve 31, and the screw 32 is threadedly connected to the threaded sleeve 31. One end of the screw 32 extends outward through the end of the threaded sleeve 31. A retaining sleeve 33 is connected to the outer end of the screw 32, and the retaining sleeve 33 is rotatably connected to the screw 32. A pin 34 is connected to the middle of the retaining sleeve 33. Limiting posts 35 extend upward from both sides of the upper end of the guardrail 2. Both the middle of the retaining sleeve 33 and the middle of the limiting post 35 are provided with insertion holes 340 that match the pin 34. After the angle of the guardrail 2 is adjusted, the sleeve 33 is moved to the upper end of the limiting post 35 by rotating the rotating ring 30 and the screw 32. The two insertion holes 340 are aligned and the pin 34 is inserted to fix the guardrail 2 to the post 1, thereby completing the angle fixation, improving the stability and protection of the guardrail, and avoiding the problem of easy deformation of the guardrail under external force.

[0040] In one embodiment, two rotating rings 30 are stacked vertically and located on the same center line as the column 1, and both rotating rings 30 can rotate around the center line of the column 1. A knob 36 is connected to the outer surface of the end of the screw 32, which allows the operator to rotate the screw 32 by rotating the knob 36.

[0041] In one embodiment, the upright 1 includes a central upright 10, with vertical rods 11 connected to both opposite sides of the central upright 10. Several retaining rings 12 are connected to the opposite sides of each of the two vertical rods 11, and the retaining rings 12 can rotate around the center line of the vertical rods 11. The guardrail 2 includes a plate 20, with several guide rods 21 matching the retaining rings 12 connected to both sides of the plate 20. By inserting the guide rods 21 into the retaining rings 12, the plate 20 is connected to the vertical rods 11, enabling quick assembly and disassembly. Simultaneously, the plate 20 can rotate via the guide rods 21 and retaining rings 12, adjusting its angle for easy folding, storage, and transportation without disassembly, thus improving the ease of use of the guardrail.

[0042] In one embodiment, the outer surface of the vertical rod 11 is provided with several arc-shaped grooves 110 that match the retaining rings 12. The retaining rings 12 can rotate within the arc-shaped grooves 110, facilitating the rotation of the plate 20. The guide rod 21 has an L-shaped structure, and the height of each guide rod 21 is less than the distance between any two adjacent retaining rings 12. The guide rod 21 and the retaining rings 12 are connected by a straight-up-down plug-in connection to avoid motion interference caused by the small distance between the retaining rings 12.

[0043] In one embodiment, the plate 20 has a double-sided groove 22 in the middle, and advertising or warning signs can be placed in the double-sided groove 22. Each double-sided groove 22 is connected to a transparent panel 23 at its outer end, which protects the signs and facilitates recycling.

[0044] In one embodiment, a cross-shaped base 13 is connected to the lower end of the central column 10. The base 13 can be placed on a flat surface to ensure the stability of the column 1. A guide groove 14 is provided in the middle of the base 13, and an insertion rod 15 is provided in the guide groove 14. The insertion rod 15 can slide up and down along the guide groove 14. By pushing the insertion rod 15 downward, it can be inserted into the soil to support the column 1 on the muddy ground. This structure allows for easy switching of the fixing method according to the terrain, improving the stability and applicability of the guardrail.

[0045] In one embodiment, a bolt 16 is connected to the bottom of the side wall of the base 13, and two through holes 150 matching the bolt 16 are provided on the side wall of the insertion rod 15. The insertion rod 15 is fixed to the base 13 by passing the bolt 16 through the base 13 and the insertion rod 15.

[0046] In one embodiment, the upper ends of the insertion rod 15 extend outward on both sides to form pedals 17, and the base 13 has through holes 130 on both sides that match the pedals 17. By stepping on the pedals 17, the insertion rod 15 is inserted into the soil to achieve the fixing function.

[0047] The specific usage process of this utility model is as follows: By inserting the guide rod 21 into the corresponding retaining ring 12 on the side of the vertical rod 11, the installation operation is carried out. The position of the column 1 is adjusted according to the actual terrain. Then, the rotating ring 30 and the screw 32 are rotated to move the retaining sleeve 33 to the upper end of the limiting post 35. After aligning the two insertion holes 340, the pin 34 is inserted to fix the fence 2 and the column 1, thus completing the angle fixation.

[0048] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
