[0022] Please refer to Figure 1-5 A foldable construction fence includes two adjacent fence bodies 1. A first connecting component 2 is fixedly installed on the center of the back of each fence body 1. One end of the first connecting component 2 has a matching slot 21, in which a diagonal brace 3 is engaged. The first connecting component 2 and the diagonal brace 3 are fixedly connected by a movable bolt. The end of the diagonal brace 3 is fixedly connected to a bottom rod 4 by a movable bolt. The end of the bottom rod 4 is fixedly connected to a second connecting component 5 by a movable bolt. One side of the second connecting component 5 is fixedly connected to the bottom of the back of the fence body 1. A first mounting plate 6 is fixedly installed on each side of the second connecting component 5. Multiple second mounting plates 7 are fixedly installed on each side of the bottom rod 4. Multiple reserved holes 8 are opened on the surface of the first mounting plate 6 and the second mounting plate 7.

[0023] During installation, the end of the base rod 4 and the second connecting assembly 5 are fixed in place with movable bolts. Then, they are fixed to the ground foundation through the pre-drilled holes 8 on the first mounting plate 6 and the second mounting plate 7. Next, the other end of the base rod 4 is fixed to one end of the diagonal brace 3 with movable bolts. Finally, the other end of the diagonal brace 3 is initially engaged with the matching slot 21 on the first connecting assembly 2, and then the diagonal brace 3 and the first connecting assembly 2 are fixed in place with movable bolts. This completes the installation of the main body 1 of the fencing. In case of typhoon weather, the fencing can be quickly lowered by removing the bolts connecting both ends of the base rod 4 and the bolts on the first mounting plate 6. This device simplifies on-site operation and improves the environmental adaptability and safety of the equipment.

[0024] In this embodiment, a first sleeve 9 is fixedly installed on one side of the main body 1 of the fencing, and a second sleeve 10, a snap-fit ​​sleeve 11, and a bolt sleeve 12 are fixedly installed on the other side of the main body 1 of the fencing. The snap-fit ​​sleeves 11 on the corresponding sides of the two main bodies 1 of the fencing are detachably snapped onto the surface of the first sleeve 9, and the second sleeve 10 and the bolt sleeve 12 are located at the top and bottom of the first sleeve 9, respectively. The holes inside the first sleeve 9, the second sleeve 10, and the bolt sleeve 12 are interconnected. Fixing nails 13 are snapped onto the inner walls of the second sleeve 10 and the first sleeve 9, and a threaded rod 14 is fixedly installed at the bottom of the fixing nail 13. The surface of the threaded rod 14 is fixedly connected to the inner wall of the bolt sleeve 12 by threads.

[0025] This device uses a first sleeve 9 and a snap-fit ​​sleeve 11 on one side of two main fence units 1 to achieve initial fixation. Then, a fixing nail 13 is inserted into the second sleeve 10 and the first sleeve 9 to initially connect the two fence units 1. Finally, rotating the fixing nail 13 connects the threaded rod 14 at the bottom of the fixing nail 13 to the bolt sleeve 12 via threads, thus finally fixing the two fence units 1. This connection method not only enables rapid splicing between fence units but also allows for free adjustment of the included angle between the two fence units 1, enabling the fence to adapt well to complex and varied terrain conditions at construction sites and increasing the device's practicality.

[0026] In this embodiment, a counterweight cavity 22 is provided inside the main body 1 of the enclosure. An adding cylinder 15 is fixedly installed on one side of the top of the main body 1 of the enclosure, and the interior of the adding cylinder 15 communicates with the counterweight cavity 22.

A handle 20 is fixedly installed on one side of the second rubber cap 19.

[0027] This device allows for the addition of water to the counterweight cavity 22 within the main body of the fence 1 by rotating the first rubber cap 16. When the counterweight needs to be reduced, the release port 18 can be opened by pulling the handle 20 to release water and further reduce the weight. This method of adjusting the counterweight solves the problems of bulkiness and inconvenience associated with traditional fences using solid counterweight materials such as sandbags or concrete blocks, enabling flexible adjustment of the counterweight and facilitating transportation and storage.

[0028] In this example, a foldable construction fence is used. Initial fixation is achieved by engaging the first sleeve 9 and the snap-fit ​​sleeve 11 on one side of the two main fence bodies 1. Then, fixing nails 13 are inserted into the second sleeve 10 and the first sleeve 9 and rotated to connect the threaded rod 14 at the bottom of the fixing nail 13 to the bolt sleeve 12 via threads, thus finally fixing the two main fence bodies 1. This sequential connection can enclose the construction area. The first connecting component 2 and the diagonal brace 3, as well as the second connecting component 5 and the base rod 4, are then fixed together using movable bolts. The ends of the base rod 4 and the diagonal brace 3 are then fixed together using movable bolts. Finally, the fence is fixed to the ground foundation through the pre-drilled holes 8 on the first mounting plate 6 and the second mounting plate 7. In case of typhoon weather, the fence can be quickly lowered by simply removing the bolts connecting both ends of the base rod 4 and the bolts on the first mounting plate 6.
