[0002] In medical building construction, protective fences are an essential building facility, playing a vital role in managing the construction site. Currently, existing fence structures generally consist of guardrails and posts. During installation, the guardrails and posts are arranged in a straight line on the ground, with intervals between them. Adjacent guardrails and posts are connected and fixed together by multiple bolts and nuts to form the fence. A base is fixed at the bottom of the post, and finally, the base is fixed to the ground with anchor bolts, thus completing the installation of the fence on the ground.

[0003] A search revealed a construction management fence (publication number CN221646561U) comprising a scissor-type telescopic link, a column structure, and a base. Several scissor-type telescopic links and column structures are arranged in a straight line and alternately. The base is detachably mounted on the bottom of the column structure. Compared to existing technologies, the advantages are: the scissor-type telescopic link, when deployed, can function as the guardrail structure of a traditional fence. Therefore, by disassembling the fence into column structures, scissor-type telescopic links, and bases, and shortening the scissor-type telescopic link, the fence can be more easily loaded and transported, and the shortened scissor-type telescopic link occupies less space. The assembly and disassembly of the scissor-type telescopic link and column structure can be completed by controlling a handwheel to drive the relative or opposite movement of two U-shaped plates. The base is also easily installed and removed from the column structure, making the installation of this fence more time-saving and labor-saving.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 3This utility model provides an embodiment of a construction management fence, comprising a fence panel 1 and a U-shaped rod 4 connected by cross-rotation. Each end of the fence panel 1 is rotatably connected to a fixing lug 2, and each end of the fixing lug 2 is fixedly connected to a connecting ring 3. The connecting ring 3 is movably connected to the outside of the U-shaped rod 4. The fence panel 1 and the U-shaped rod 4 are connected to the ground via support columns. Multiple limiting rings 8 are provided on the outside of the U-shaped rod 4. Fasteners 10 are threadedly connected to the front side of each limiting ring 8, and the inner end of the fasteners 10 is in close contact with the outer wall of the U-shaped rod 4. Limiting grooves 7 are opened on the left and right sides of the U-shaped rod 4. Multiple protrusions 9 are slidably connected to the inner side of each limiting groove 7, and the outer ends of the protrusions 9 are respectively fixedly connected to the inner side of the limiting rings 8. A threaded section 5 is provided on the outer side of the bottom end of the U-shaped rod 4, and threaded caps 6 are threadedly connected to the outer side of each threaded section 5.

[0026] The connecting ring 3 can slide up and down and rotate on the outside of the U-shaped rod 4. The two intersecting guardrails 1 rotate through the central rotating shaft and are connected to the U-shaped rod 4 through the fixing lug 2 and the connecting ring 3. Multiple sets of guardrails 1 and multiple U-shaped rods 4 are alternately connected to form a fence. The fence can be folded and unfolded by the cross rotation of the guardrails 1. When in use, it can be unfolded to prevent unauthorized personnel from entering the construction site. When facing curved terrain, the fence can be made into an arc shape by rotating the guardrails 1 and U-shaped rods 4 through the connecting ring 3, making it convenient to use and transport. Folding reduces the difficulty of handling. After folding, the fence can be rolled into a column shape by rotating the connecting ring 3, making it easy to move. The limiting ring 8 can restrict the range of movement of the fence panel 1 through the connecting ring 3. The closer the distance between the upper and lower limiting rings 8, the greater the range of movement of the connecting ring 3, and the longer the fence can be formed. By rotating the threaded cap 6, the threaded cap 6 can be removed from the bottom of the U-shaped rod 4, and the U-shaped rod 4 can be pulled out from the limiting ring 8 and the connecting ring 3, so as to facilitate the replacement of damaged parts of the fence and continue to use the undamaged parts, avoiding waste.

A fixing rod 16 is fixedly connected inside the column body 11, and a lifting rod 17 is movably connected to the upper end of the fixing rod 16. The upper end of the lifting rod 17 passes through the inside of the column body 11. A spring 18 is provided inside the lifting rod 17 corresponding to the top of the fixing rod 16. Movable grooves 15 are provided on the left and right sides of the column body 11 and the cover plate 12. Lifting blocks 19 are movably connected up and down inside the movable grooves 15. The inner ends of the lifting blocks 19 are fixedly connected to the left and right sides of the lifting rod 17, respectively. Fixing rings 20 are fixedly connected to the outside of the U-shaped rods 4 on the left and right sides. A pin 21 is fixedly connected to the end of the fixing ring 20. The lower end of the pin 21 passes through the inner end of the lifting block 19.

[0028] Pass the fixing pin through the through hole 14 to fix the column 11, cover plate 12 and pad 13 in the appropriate position. The fixing ring 20 and pin 21 on the outside of the leftmost and backmost U-shaped rod 4 are used to connect with the support column. Insert the lower end of the pin 21 into the lifting block 19 so that the fence is installed between the two support columns. When disassembling, hold the U-shaped rod 4 with one hand and press the lifting rod 17 from the top of the column 11 with the other hand. The lifting rod 17 drives the lifting block 19 to descend and compress the internal spring 18. The descending lifting block 19 separates from the pin 21, making it easy to remove the fence plate 1 and connecting ring 3. The installation is convenient and the disassembly is simple.

[0029] Working principle: The fixing pin is passed through the through hole 14 to fix the pad 13 and column 11 in a suitable position. Then, the lower end of the pin 21 is inserted into the lifting block 19 set on the column 11. The U-shaped rod 4 is pulled from the other end of the fence, inserting the pin 21 at the other end into the lifting block 19 set on another column 11. This process is repeated multiple times to enclose the construction site. During the stretching process, the column 11 rotates through the central pivot, causing the connecting ring 3 to slide outside the U-shaped rod 4, completing the stretching. The fence panel 1 can slide outside the U-shaped rod 4 through the connecting ring 3. The part rotates, so that the fence forms an arc shape when facing the curved terrain; rotate the threaded cap 6 to remove the threaded cap 6 from the bottom of the U-shaped rod 4, rotate the fastener 10 to remove the fixation of the limit ring 8, and pull the U-shaped rod 4 out from the limit ring 8 and the connecting ring 3, and replace the damaged parts of the fence; when retrieving the fence, hold the U-shaped rod 4 with one hand and press the lifting rod 17 from the top of the column 11 with the other hand. The lifting rod 17 drives the lifting block 19 to descend and compresses the internal spring 18. The descending lifting block 19 separates from the pin 21, making it easy to remove the fence panel 1 and the connecting ring 3.
