When the lower shielding frame 3 is closed, the fence plays an isolation role;

[0022] Three equally spaced linear grooves 101 are provided on one outer wall of the profile frame 1, and three equally spaced docking plates 7 are provided on the other outer wall of the profile frame 1. The docking plates 7 and the linear grooves 101 are plugged into each other. A three-way bolt connector for bolting to the docking plates 7 is installed at the top of the profile frame 1 on one side of the linear grooves 101.

[0023] A protruding tongue 1 201 is fixed to one side of the bottom end of the lower circular inner frame 2, and a protruding tongue 2 301 is provided on the outer wall of one side of the lower shielding frame 3 and is bolted to the protruding tongue 1 201. When opening the lower shielding frame 3, the staff releases the bolting restriction of the protruding tongue 1 201 and the protruding tongue 2 301, so that the lower shielding frame 3 can be flipped upward and opened. Compared with a single entrance and exit, multiple temporary entrances and exits disperse the flow of people in and out of the construction site, reduce congestion and waiting in queues, and improve entry and exit efficiency. Especially when frequent entry and exit are required, this design can better meet the needs of the construction site and reduce waiting time for personnel and equipment.

[0024] Several square columns 6 are fixed at equal intervals inside the upper circular inner frame 5. The upper circular inner frame 5 and the square columns 6 are all made of stainless steel. Stainless steel has corrosion resistance and can maintain good appearance and performance for a long time.

[0025] The three-way bolt connector includes a boss 8 fixed to one side of the top end of the profile frame 1, and three equally spaced positioning plates 9 on the outer wall of the boss 8. The angle between adjacent positioning plates 9 is ninety degrees. The top end of the docking plate 7 is provided with an internal threaded countersunk hole 701, and the top end of the positioning plate 9 is provided with a positioning hole 901. After the docking plate 7 and the linear groove 101 are plugged in, the positioning hole 901 and the internal threaded countersunk hole 701 are concentric with each other. To connect multiple profile frames 1, the docking plate 7 is inserted into the linear groove 101 on the outer wall of another profile frame 1. After the docking plate 7 is plugged into the limit position, the staff takes out the bolt and passes the bolt through the positioning hole 901 until the positioning hole 901 is screwed into the internal threaded countersunk hole 701 of the docking plate 7, so that the docking plate 7 and the positioning plate 9 are fixed together;

[0026] The use of the straight groove 101 and the docking plate 7 can achieve fast and simple docking, saving a lot of installation time, and the docking plate 7 and the positioning plate 9 ensure that the connection between the various profile frames 1 is tight and not easy to loosen, effectively preventing the fence from tilting, collapsing and other safety problems during the construction process;

[0027] A support structure 10 is provided at the corners of the bottom end of the profile frame 1. The support structure 10 includes a protruding plate 1001 installed on the outer walls on both sides of the profile frame 1, and a foot support unit 1002 threadedly installed at the bottom end of the protruding plate 1001. The protruding plate 1001 and the foot support unit 1002 set at the edge of the bottom end of the profile frame 1 are used to support the fence, thereby ensuring the stability of the fence.

[0028] When the embodiment of the present application is in use, the staff first takes out a plurality of the fences so that the plurality of fences are arranged in a collinear manner. At this time, the relative outer walls of the two adjacent profile frames 1 are docked through the linear grooves 101 and the docking plates 7, that is, the docking plates 7 are inserted into the linear grooves 101 on the outer walls of the other profile frame 1 until the docking plates 7 are fully plugged into place. At this time, the staff can use the three-way bolts and bolts to position the docking plates 7, so as to complete the locking connection between the two profile frames 1. The staff can connect the profile frames 1 in sequence according to the same steps until a continuous and stable isolation surface is formed. The staff can also form a Another continuous isolation surface is formed, and an isolation area is formed by the isolation surface extending in a biaxial direction. When the staff needs to temporarily pass through the fence and quickly enter the isolation area, the staff can release the bolting restrictions at the lower ends of the lower circular inner frame 2 and the lower shielding frame 3, and flip the lower shielding frame 3 upward, so that the lower shielding frame 3 flips in a circular shape with a hinge, and then a square cavity appears in the lower circular inner frame 2, so that staff, materials or engineering equipment can quickly enter and exit, which makes each fence itself have the function of entry and exit, and is no longer limited to a single fixed entrance and exit. Workers and equipment can choose the entry and exit path more flexibly, and can adjust it according to actual needs.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
