For example, common welded metal fencing requires significant manpower and time for welding and assembly on-site, and disassembly after completion is equally difficult. This severely impacts construction progress in time-sensitive projects such as emergency road repairs. Faced with diverse road construction scenarios, traditional monolithic fencing struggles to adapt flexibly. Whether in narrow streets, bends, ramps, or intersections, its fixed size and structure cannot be easily adjusted according to site terrain and construction needs, limiting its application.

[0004] In order to improve the installation efficiency and size adjustment of construction safety warning fences, and to ensure the safety of construction personnel, passing vehicles and pedestrians, the applicant proposes a detachable road construction safety warning fence. Utility Model Content

[0028] In the field of road construction fence manufacturing technology, the ease of fence assembly and splicing directly affects road construction efficiency. Addressing the problems of traditional construction safety warning fences requiring multiple people to work together and being cumbersome to install, this utility model achieves rapid and efficient assembly through innovative structural design. The specific implementation method is as follows:

[0029] Example 1: A detachable road construction safety warning fence, such as Figure 1 As shown, the enclosure includes at least two symmetrically arranged fence bases 1. Support sleeves 2 are fixedly installed at the upper ends of the multiple fence bases 1. Support columns 3 are sleeved inside the support sleeves 2. A bottom crossbeam 4 and a top crossbeam 5 are installed between every two adjacent support columns 3. The bottom crossbeam 4 and the top crossbeam 5 are parallel to each other and are respectively snapped into the bottom and top of the support column 3. A detachable protective plate 6 is installed in the middle between the bottom crossbeam 4 and the top crossbeam 5. Several grid plates 7 are evenly and equidistantly arranged at both ends of the protective plate 6, and every two adjacent grid plates 7 are slidably snapped into each other.

[0030] When in use, the height of the road construction safety warning fence is adjusted by controlling the relative sliding distance between the support column 3 and the support sleeve 2, according to the required erection height. This allows for quick adjustment of the fence erection height to meet the different height requirements during construction. The bottom beam 4 and top beam 5 of corresponding lengths are selected based on the area and length of the construction area to facilitate calculation of the required fence quantity before transportation and better length setting. Two symmetrical support columns 3 are placed flat on the left and right sides respectively, with both support columns 3 lying flat on the ground to avoid damage to the bottom beam 4 and top beam 5 due to excessive bending angle when placed vertically. The bottom beam 4 and top beam 5 are inserted into one of the support columns 3. Then, the protective plate 6 and multiple grid plates 7 are interlocked and slid in between the bottom beam 4 and top beam 5. When the first grid plate 7 reaches the leftmost end, ensure that the protective plate 6 is in the middle position. Then, the bottom beam 4 and top beam 5 are inserted into the support column 3 on the other side. After all assembly is complete, the entire fence is lifted to a vertical position.

[0031] Specifically, such as Figure 1 , Figure 2 As shown, the outer wall of the support sleeve 2 is provided with a plurality of equally spaced mounting holes 8, and the outer wall of the support column 3 is provided with threaded holes 9. The mounting holes 8 are provided with fastening bolts 10 that are threadedly connected to the threaded holes 9.

[0032] By loosening the fastening bolt 10, the support column 3 can be slid out from the inside of the support sleeve 2. After adjusting the height of the fence, the support column 3 and the support sleeve 2 can be fixed by matching the fastening bolt 10 with the mounting hole 8 and the threaded hole 9.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, each symmetrical support column 3 has a U-shaped groove 11 at the top and bottom ends on one side. The bottom crossbeam 4 and the top crossbeam 5 are equipped with mounting plates 12 at both ends. The mounting plates 12 have a U-shaped cross section and are adapted to the size of the U-shaped groove 11. The bottom crossbeam 4 and the top crossbeam 5 are connected to the outer surface of the support column 3 with fixing bolts 13. The fixing bolts 13 are threaded to one end face of the bottom crossbeam 4 and the top crossbeam 5. The U-shaped cross section of the bottom crossbeam 4 and the top crossbeam 5 is adapted to the upper and lower ends of the protective plate 6 and the multiple grid plates 7, which facilitates the mutual snapping and fixing of the protective plate 6 and the multiple grid plates 7 with the bottom crossbeam 4 and the top crossbeam 5. The U-shaped structure restricts the lateral displacement of the protective plate 6 and the multiple grid plates 7, ensuring the overall stability and safety of the fence.

[0034] The U-shaped sections of the bottom crossbeam 4 and the top crossbeam 5 are snapped into the U-shaped groove 11. After being snapped into place at one end, the bottom crossbeam 4 and the top crossbeam 5 are fixed by fixing bolts 13, making them a whole with the support column 3. The bottom crossbeam 4 and the top crossbeam 5 of the U-shaped structure allow the protective plate 6 and multiple grid plates 7 to be snapped into the inside of the U-shaped structure, thereby limiting the lateral displacement of the protective plate 6 and multiple grid plates 7 and ensuring the overall stability of the structure.

[0035] In summary, a detachable road construction safety warning fence is installed by placing two symmetrical support columns 3 on the ground, inserting the mounting plates 12 at one end of the bottom beam 4 and top beam 5 into the U-shaped grooves 11, placing the protective plate 6 in the middle, and sliding the grid plate 7 into the sliding grooves 18 at both ends of the protective plate 6. The sliding grooves 18 are dovetail grooves, which improve the overall stability of the protective plate 6 and the grid plate 7 after the overall splicing. After the splicing is completed, the protective plate 6 and the grid plate 7 are snapped between the bottom beam 4 and the top beam 5, and the mounting plate 12 at the other end is snapped into the U-shaped groove 11 at the other end of the support column 3. The two are then fixed with fixing bolts 13. After fixing, the height of the fence is required according to the construction length, and the sliding length of the support column 3 relative to the support sleeve 2 is adjusted by tightening bolts 10. After the length is determined, it is fixed with tightening bolts 10 to improve the practicality of the fence.

[0036] Example 2: Based on Example 1, as follows Figure 1 As shown, a safety warning component is fixedly installed on the upper end and one end of the outer surface of the support column 3. The safety warning component includes a connecting seat 14 fixedly installed on the upper end of the outer surface of the support column 3. A warning light 15 is installed on one end of the connecting seat 14. The warning light 15 can be powered by setting an LED dry battery or a solar panel to maintain the continuous warning effect of the warning light 15 during use. A reflective warning strip 16 is glued to the front end of the outer surface of the support column 3. The reflective warning strip 16 is glued to the outer surface of the support column 3.

[0037] The warning light 15 is powered by LED dry batteries or solar panels. The warning light 15 reminds pedestrians and construction workers to pay attention to personal safety at night. At the same time, the reflective warning strip 16 reminds drivers at night to pay attention to the construction area ahead, thereby improving the safety of construction site operations and the practicality of the fence, and ensuring the safety of construction operations.

[0038] Specifically, such as Figure 3 As shown, the surface of the protective plate 6 has a through groove 17 parallel to its longitudinal direction, and a safety warning slogan and warning sign are provided on one side of the protective plate 6.

[0039] Safety warning signs and slogans can remind pedestrians and workers around the construction site, ensuring the safety of construction operations.

[0040] Specifically, such as Figure 3 , Figure 4 As shown, both ends of the protective plate 6 are provided with sliding grooves 18, which are parallel to the vertical direction of the protective plate 6. The sliding grooves 18 are dovetail grooves. One end of the grid plate 7 is provided with a locking plate 19 that matches the sliding groove 18, and the other end of the grid plate 7 is also provided with the same sliding groove 18 as the protective plate 6.

[0041] During fence assembly, the protective plate 6 is placed in the middle, and the locking plate 19 at one end of the grid plate 7 is slid into the groove 18 of the protective plate 6. The dovetail-shaped groove 18 allows the grid plate 7 and the protective plate 6 to be interlocked and fixed. The dovetail groove restricts the relative sliding of the grid plate 7 and the protective plate 6. After installation, the locking plate 19 at one end of the other grid plate 7 is aligned with the groove 18 of the grid plate 7 to complete the interlocking and fixing. This operation is performed in sequence to complete the splicing of one end of the protective plate 6. The other end of the protective plate 6 is spliced ​​in the same way. The two ends of the protective plate 6 are spliced ​​symmetrically with respect to its central axis. After the two ends are spliced, the spliced ​​whole can be interlocked between the bottom crossbeam 4 and the top crossbeam 5 for overall fixation.

[0042] In summary, when in use, the safety warning fence uses warning lights 15 to remind pedestrians and construction workers to pay attention to personal safety. At the same time, the reflective warning strips 16 and the eye-catching safety warning slogans and signs remind drivers driving at night to pay attention to the construction area ahead, thereby improving the safety of construction site operations and the practicality of the fence, and ensuring the safety of construction operations.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
