[0002] During municipal construction, fences are needed to isolate the construction area to prevent pedestrians or vehicles from entering by mistake and causing accidents. The existing fences are mainly composed of brackets and protective plates that play a blocking role. The brackets and protective plates are connected by screws, and the brackets provide support to stand the protective plates in the construction area.

[0003] After the construction task is completed, the fence needs to be dismantled and the dismantled brackets and protective plates are transported away by a transport vehicle. It should be noted that the protective plates are large in size and need to be stacked and transported in batches multiple times. The protective plates are large and thin components, and their surfaces are easily dented and scratched during transportation, which is not conducive to secondary use.

[0004] Therefore, how to make the isolation fence easy to disassemble and transport and avoid it from being damaged during transportation is a problem that needs to be solved. Utility Model Content

[0034] See also Figure 1The utility model provides an isolation fence 10 for municipal engineering construction, including: an external fixing frame 11 and a rolling curtain type isolation plate 12.

[0035] See also Figure 2 and Figure 6 The rolling-up isolation plate 12 includes a plurality of isolation monomers 100, each of which is provided with a protrusion 110 and a docking portion 120. The protrusion 110 and the docking portion 120 are respectively located on two opposite side surfaces of the isolation monomer 100. The protrusion 110 is used to be rotatably connected with the docking portion 120 on the adjacent isolation monomer 100. The adjacent isolation monomers 100 are connected together through the protrusion 110 and the docking portion 120. Since the protrusion 110 and the docking portion 120 are rotatably connected, the isolation monomer 100 rotates around the connection position between the protrusion 110 and the docking portion 120, thereby enabling the rolling-up isolation plate 12 to have a winding capability. In this way, when laying the isolation fence, the rolling curtain isolation board 12 is unfolded; when dismantling the isolation fence, the rolling curtain isolation board 12 can be rolled up, so that the rolling curtain isolation board 12 has the ability to be rolled up, which is convenient for carrying it after dismantling, and after being rolled up, the side with the logo (such as construction notices, warning information, etc.) on it is on the inside, and even if multiple rolling curtain isolation boards 12 are stacked together for transportation, they will not be scratched.

[0036] See also Figure 1 and Figure 3 The external fixing frame 11 includes a plurality of columns 200, and a limiting module is provided between each two adjacent columns 200, and the limiting module includes a first limiting sleeve 310 and a second limiting sleeve 320, and the first limiting sleeve 310 and the second limiting sleeve 320 are provided with a groove 330, and the end of each isolation unit 100 is inserted into the groove 330, and the first limiting sleeve 310 and the second limiting sleeve 320 are used to buckle the edge of the rolling-up isolation plate 12, so as to provide a holding force for each isolation unit 100, so that the rolling-up isolation plate 12 is kept in the expanded state.

[0037] Among them, see Figure 3 The column 200 includes a base 210, an end cover 220 and two clamps 230 arranged opposite to each other. The base 210 is provided with a first slot 211, one end of the clamp 230 is inserted into the first slot 211, the end cover 220 is provided with a second slot 221, and the other end of the clamp 230 is inserted into the second slot 221.

[0038] The two clamps 230 cooperate to clamp the front and back sides of the rolling curtain isolation plate 12, and the two ends of the clamps 230 are respectively inserted into the first slot 211 and the second slot 221, and the foot 210 and the end cover 220 cooperate to apply a clamping force to the two clamps 230, thereby fixing the clamps 230.

[0039] The process of erecting the isolation fence 10 for municipal engineering construction is as follows:

[0040] First, lay a plurality of plywood 230 on the ground, align the ends of each plywood 230, and reserve a sufficient interval between the plywood 230 (the interval is greater than the length of the plywood 230). Press the rolled-up roll-up insulation board 12 onto the first plywood 230 (such as Figure 4 As shown), push the rolling curtain type isolation plate 12 to roll it until it is fully unfolded, the rolling curtain type isolation plate 12 is pressed on the clamping plate 230, and the position of the clamping plate 230 is adjusted so that the two ends of the clamping plate 230 are not covered by the rolling curtain type isolation plate 12 (as shown in FIG. Figure 5 shown).

[0041] Next, the second limiting sleeve 320 is brought close to the rolling curtain isolation plate 12, the first end of each isolation unit 100 is inserted into the first limiting sleeve 310, and the end of the first limiting sleeve 310 is placed on the clamping plate 230; the second end of the isolation unit 100 is inserted into the second limiting sleeve 320 in the same manner, and the end of the second limiting sleeve 320 is placed on the clamping plate 230;

[0042] Finally, place the clamping plate 230 on the rolling screen isolation board 12 and align it with another clamping plate 230 laid on the ground, and insert the two ends of the clamping plate 230 into the first slot 211 and the second slot 221 to complete the assembly operation. Stand up the assembled isolation fence, move it to the target location, and fix it with ground nails.

[0043] It should be noted that the foot seat 210 (and the end cover 220) is directly mounted on the end of the clamping plate 230 to complete the splicing, which is an interference fit and does not require screws for fixing, thereby saving assembly and disassembly time.

[0044] The disassembly process of the isolation fence 10 used for municipal engineering construction is as follows:

[0045] Use a crowbar (or other nail-pulling tools) to pry open the ground nails, push the isolation fence backward, grab the foot 210, and apply force along the long side direction of the clamping plate 230 until the foot 210 is separated from the clamping plate 230; use the same method to remove the end cover 220 and release the lock on the clamping plate 230.

[0046] After the clamping plate 230 is removed, the rolling curtain type isolation plate 12 can be rolled up. The first limiting sleeve 310, the second limiting sleeve 320 and the clamping plate 230 are all slender components, which are convenient for loading them into the carriage together with the rolled-up rolling curtain type isolation plate 12 for transportation.

[0047] The above-mentioned isolation fence 10 for municipal engineering construction has the following advantages:

[0048] 1. The isolation monomers 100 are rotatably connected. After removing the external fixing frame 11, the rolling curtain isolation board 12 can be rolled into a bundle to reduce the volume and facilitate transportation. The surface area of ​​the rolling curtain isolation board 12 becomes smaller after rolling, and it is not easy to be crushed during transportation. Moreover, the exposed surface is hidden after rolling, which can prevent the notice information coated on the surface of the rolling curtain isolation board 12 from being scratched;

[0049] 2. The foot 210 and the end cover 220 are respectively buckled on the two ends of the clamping plate 230, providing clamping force for the first limiting sleeve 310, the second limiting sleeve 320 and the two clamping plates 230. When disassembling, it is only necessary to pull out the end cover 220 and the foot 210 along the extension direction of the clamping plate 230 to release the clamping force. Compared with the screw connection structure, the disassembly and assembly process is efficient.

[0050] See also Figure 7 and Figure 8 The docking portion 120 is provided with an arc-shaped avoidance surface 121 and a stop surface 122. The arc-shaped avoidance surface 121 provides space for the adjacent isolation units 100 to flip, and the stop surface 122 is used to abut against the outer wall of the isolation unit 100 to provide a limit, so that the isolation unit 100 can only rotate in one direction, so that the rolling or unfolding direction of the rolling curtain type isolation board 12 is fixed, which is convenient for construction workers to distinguish the front and back sides.

[0051] See also Figure 3 and Fig. 9 In order to improve the structural stability, the clamping plate 230 is provided with an anti-slip strip 231, and the outer walls of the first limiting sleeve 310 and the second limiting sleeve 320 are provided with a recessed portion 340 matching the anti-slip strip 231. The clamping plate 230 is provided with a limiting step 232 at both ends, and the anti-slip strip 231 is located on the limiting step 232. During assembly, the end of the first limiting sleeve 310 (or the second limiting sleeve 320) is placed on the limiting step 232, and the anti-slip strip 231 is embedded in the recessed portion 340. After the isolation fence is assembled, the clamping force provided by the clamping plate 230 can make the recessed portion 340 clamp the anti-slip strip 231, preventing the end of the first limiting sleeve 310 (or the second limiting sleeve 320) from being pulled out of the clamping plate 230.

[0052] Preferably, see Figure 2 A reflective mark 321 is attached to the outer wall of the second limiting sleeve 320. The reflective mark 321 reflects the lamp housing at night, so that the driver can observe the position of the isolation fence to avoid traffic accidents.

[0053] See also Figure 7 and Figure 8, the column 200 also includes a flange 240 and a pad 250. The flange 240 is arranged at the bottom of the foot 210. The pad 250 has a hollow portion 251 on the side in contact with the flange 240. The pad 250 and the flange 240 are connected in a separate manner. The ground nails are inserted into the ground after passing through the flange 240 and the pad 250. When the isolation fence needs to be dismantled, the end of the crowbar (or other nail-pulling tools) is inserted into the hollow portion 251 to pry the pad 250 open. When the pad 250 is separated from the flange 240, the ground nails are pulled out from the ground to improve the disassembly efficiency.

[0054] In one embodiment, please refer to Figure 3 The second limiting sleeve 320 is provided with an auxiliary support portion 322. The auxiliary support portion 322 is in contact with the ground and is supported by the auxiliary footrest 210 to improve the anti-dumping ability of the isolation fence.

[0055] Preferably, see Figure 3 A mounting surface 222 is provided on the top of the end cover 220, and a warning light can be provided on the mounting surface 222 to warn pedestrians and passing vehicles.

[0056] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
