Description

Technical Field

[0001] The utility model relates to the technical field of municipal construction tools, in particular to a folding enclosure for municipal engineering construction which has a simple structure, high overall strength and is easy to install, disassemble and transport. Background Art

[0002] As we all know, fencing is a measure taken to isolate the construction site from the external environment and make the construction site a relatively closed space. In order to achieve multiple recycling, the existing fencing structure generally includes a baffle and a base. The lower end of the baffle is fixedly connected to the base, and the base is fixed on the ground.

[0003] At present, in order to increase the utilization rate of the fence, metal or plastic structures are generally used. The fences for normal construction are generally surrounded, so a large number of fences are required for splicing. However, since the fence includes two structures, the baffle and the base, its transportation is very inconvenient, and in order to increase the stability of the structure, the existing fence generally requires a counterweight to fix the base. Therefore, the counterweight part also increases the burden of transportation. In order to reduce the transportation burden of the counterweight part, especially the existing counterweight structure generally uses sand bags, but the bags are affected by natural factors and operations, resulting in low reusability, and for the sake of trouble, all are treated as waste; at the same time, in order to achieve reusability, the baffle and the base are split and metal structures are used, which are also very easy to lose. Summary of the invention

[0023] Furthermore, a slot is provided at the rear end of the base 1, and a counterweight box 13 is provided in the slot. The upper end of the counterweight box 13 is open, and the lower end of the counterweight box 13 is connected to a socket 14 that cooperates with the slot. The socket 14 is inserted into the slot and fixedly connected to the base 1.

[0024] Furthermore, the upper end of the upper connecting rod 4 is connected to the upper end of the baffle 2, which reduces the length of the upper connecting rod 4, saves materials and ensures the supporting effect.

[0025] Furthermore, the base 1 is configured as a frame structure, which includes a square frame 9 and a transverse rod 10 . The inner rear end of the square frame 9 is connected to the transverse rod 10 , and a slot is formed between the transverse rod 10 and the rear end of the square frame 9 .

[0026] Furthermore, a spacer rod 11 is provided in the middle of the transverse rod 10, one end of the spacer rod 11 is fixedly connected to the middle of the transverse rod 10, and the other end of the spacer rod 11 is fixedly connected to the middle of the rear end of the square frame 9, and the spacer divides the slot into two unit slots 12, and a counterweight box 13 that cooperates with the unit slot 12 is placed in the unit slot 12.

[0027] Furthermore, a socket 15 is provided on the base 14 at the bottom of the counterweight box 13, and a plug hole 18 corresponding to the position of the socket 15 is provided on the base 1. The insertion rod 17 is inserted into the socket 15 of the base 14 of the counterweight box 13 through the plug hole 18, thereby fixing the counterweight box 13.

[0028] Furthermore, the counterweight box 13 is filled with sand to counterweight the counterweight box 13 .

[0029] Furthermore, the left and right baffles 2 are respectively provided with docking plates 19, and the docking plates 19 are provided with through holes. The docking plates 19 between adjacent baffles 2 are stacked and connected by connecting bolts 20 and connecting nuts 21 passing through the through holes, thereby realizing the connection between the baffles 2 of adjacent enclosures.

[0030] Furthermore, the insertion hole 15 is a threaded hole, and the end of the insertion rod is provided with an external thread that matches the threaded hole, and the insertion rod is connected to the insertion hole through the thread.

[0031] When the utility model is in use, the baffle 2 is folded on the base 1, multiple enclosures can be folded for transportation, multiple counterweight boxes 13 can be stacked for transportation, and multiple insertion rods 17 can be placed in each counterweight box 13. When it is needed to be used as an enclosure, the baffle 2 and the base 1 are opened, and the upper connecting rod 4 on the baffle 2 is connected to the lower connecting rod 5 of the base 1 through the locking bolt 7 and the locking nut 8. After the connection, the upper connecting rod 4 and the lower connecting rod 5 are straight rods, and form a triangular support with the side of the baffle 2 and the base 1, and then the counterweight boxes 13 are respectively placed in the unit card slots 12 of the base 1, and then the insertion rods 17 in each counterweight box 13 are taken out, and the insertion rods 17 are inserted into the card seat 1 of the counterweight box 13 through the insertion hole 18 of the base 1. 4, and then fill the counterweight box 13 with sand, and after filling, the installation of an enclosure is realized. The adjacent enclosures are stacked through the docking plates 19 on the enclosures, and after stacking, they are fixed with connecting bolts 20 and connecting nuts 21 to realize the installation of adjacent enclosures. After use, the connecting bolts 20 and connecting nuts 21 on the connecting plates 6 on the baffles 2 of the adjacent enclosures are removed, and the sand in the counterweight box 13 is shoveled out, and then the insertion rod 17 under the counterweight box 13 is taken out, and then the counterweight box 13 is removed, and finally the locking bolts 7 and locking nuts 8 on the connecting plate 6 between the upper connecting rod 4 and the lower connecting rod 5 are removed, and the upper connecting rod 4 is folded toward the baffle 2, and the lower connecting rod is tightened. 5 is folded toward the base 1, and finally the baffle plate 2 is folded on the base 1, the storage of the enclosure is completed, and finally it is placed on the transport vehicle and stacked and pulled away. Since the baffle plate 2 and the base 1 of the enclosure are set to be foldable, the transportation area can be reduced and the transportation volume can be increased. At the same time, the counterweight box 13 can be stacked and placed, which reduces the space occupied during transportation. Moreover, the counterweight box 13 is connected to the base 1 through the insertion rod 17. After the counterweight box 13 is filled with sand and soil, the counterweight box 13 is pressed on the base 1, thereby squeezing the insertion rod 17, and the insertion rod 17 cannot be directly withdrawn. The sand and soil must be cleaned out and the counterweight box 13 must be gently lifted to withdraw the insertion rod 17. Therefore, the risk of theft is reduced, and it is not easy to lift it up and leave, but it needs to be lifted up. It is necessary to clean up the mud and sand, and at the same time, the end of the plug rod is threadedly connected to the socket on the holder of the counterweight box, so the plug rod needs to be rotated and removed before it can be taken away, therefore, the risk of theft is further increased. Therefore, this structure can reduce the risk of theft, ensure the overall counterweight of the enclosure, and is also convenient for transportation. It has high overall strength and strong wind resistance, which can prevent theft, improve efficiency, and save a lot of labor and mechanical equipment costs. At the same time, a drainage hole is provided at the bottom of the inner cavity of the counterweight box, which is conducive to drainage. When the counterweight box is made of metal, its service life can be increased. Due to the adoption of the above-mentioned structure, the utility model has the advantages of simple structure, high overall strength, good stability, strong wind resistance, anti-theft, easy installation, disassembly and transportation.
