Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and more specifically, to a protective fence for building construction. Background Technology

[0002] Protective fencing refers to a fence or barrier erected around construction sites, activity venues, or private property. It is a measure taken to isolate the construction site from the external environment, making the construction site a relatively closed space. It includes walls built with various masonry materials and protective structures made of various prefabricated panels.

[0003] Construction site safety barriers, as core protective facilities at construction sites, play a crucial role in isolating work areas and ensuring pedestrian safety. With increasingly stringent environmental regulations, construction dust control has become a mandatory standard. Traditionally, mist cannons or sprinkler towers are erected separately on the outside of the barriers. However, this method requires a large area and multiple mist cannons or sprinkler towers to cover the entire construction site, resulting in high construction costs. While solutions exist that integrate protective barriers with dust suppression by attaching sprinkler pipes, directly connecting the pipes during barrier assembly requires separate connections to each barrier, making it inconvenient to use. Furthermore, the sprinkler pipes attached to the barriers cannot adjust the spray angle, leading to poor dust suppression effectiveness. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a protective fence for construction projects, which aims to solve the problems existing in the prior art.

[0005] This utility model provides a protective fence for construction projects, which includes a fence frame, baffles, and spray pipes; wherein...

[0031] Various embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. In the various drawings, the same elements are indicated by the same or similar reference numerals. For clarity, the various parts in the drawings are not drawn to scale.

[0032] This utility model provides a protective fence for construction projects, see [link]. Figures 1 to 3 The construction protective fence includes a fence frame 1, a baffle 2, and a spray pipe 5. The fence frame 1 includes an upper horizontal bar 11 and a lower horizontal bar 12 arranged in parallel, and several vertical bars 13 connecting the upper and lower horizontal bars 11 and 12. A first mounting rod 3 and a second mounting rod 4 are vertically arranged at both ends of the fence frame 1. The baffle 2 is connected to the fence frame 1. A spray pipe 5 is rotatably mounted on the top of the fence frame 1, and several nozzles 51 are mounted on the spray pipe 5. A guide pipe 6 is installed inside the upper horizontal bar 11, and the spray pipe 5 is connected to the guide pipe 6 inside the upper horizontal bar 11 via a connecting pipe 52. A connecting groove 31 is provided at the upper end of the first mounting rod 3, and the connecting groove 31 is connected to the first end of the guide pipe 6 in the upper horizontal bar 11. The second end of the guide pipe 6 extends a predetermined length outside the second mounting rod 4, and the second end of the guide pipe 6 is adapted to the opening of the connecting groove 31.

[0033] Specifically, the upper and lower ends of the vertical rod 13 can be connected to the upper horizontal rod 11 and the lower horizontal rod 12 by welding. In this embodiment, the enclosure frame 1 includes two vertical rods 13, which are symmetrically arranged on both sides of the middle position of the upper horizontal rod 11. The first mounting rod 3 and the second mounting rod 4 are fixedly connected to both sides of the enclosure frame 1 by welding, and both the first mounting rod 3 and the second mounting rod 4 are perpendicular to the upper horizontal rod 11 and the lower horizontal rod 12. In specific implementation, anchor plates can be provided at the bottom of the first mounting rod 3 and the second mounting rod 4 for anchoring the first mounting rod 3 and the second mounting rod 4 to the ground by anchor bolts.

[0034] When multiple construction site protective barriers are spliced ​​together to enclose the construction site, the second end of the guide pipe 6 of one protective barrier can be inserted into the connecting groove 31 of the adjacent protective barrier. This allows all the guide pipes 6 of the protective barriers to be connected together. After splicing, the multiple protective barriers only need to be connected to a single water inlet pipe to supply water to the spray pipes 5 of all the spliced ​​protective barriers. The spray nozzles 51 on the spray pipes 5 spray the dust at the construction site, greatly improving the dust control effect.

[0035] like Figure 1 and Figure 2 As shown, two fixing blocks 111 are spaced apart at the top of the enclosure frame 1, and the two ends of the nozzle 5 are rotatably connected to the fixing blocks 111. Specifically, each fixing block 111 has a through hole, and the two ends of the nozzle 5 are rotatably disposed in the through hole; one of the fixing blocks 111 is provided with a locking member for locking and fixing the nozzle 5. In this embodiment, the locking member is a locking bolt 112, and one of the fixing blocks 111 has a threaded through hole that communicates with the through hole. The locking bolt 112 is screwed into the threaded through hole, and the nozzle 5 can be locked and fixed by turning the locking bolt 112. One end of the nozzle 5 is provided with a hand crank 53, and the other end of the nozzle 5 is connected to the guide pipe 6 through the connecting pipe 52. The nozzle 5 and the connecting pipe 52 are connected by a rotary joint. By rotatably connecting the nozzle 5 to the top of the enclosure frame 1, the nozzle 5 can be easily rotated by the hand crank 53 to adjust the angle of the nozzle 51 on the nozzle 5, so as to spray dust at different angles according to the specific conditions of the construction site.

[0036] Preferably, a ball valve (not shown in the figure) can be installed on the connecting pipe 52 to open one or more ball valves on the connecting pipe 52 of the protective enclosure to supply water to the spray pipe 5, so as to achieve spray dust suppression in local areas of the construction site.

[0037] Furthermore, at least two rotating rods 71 ​​are rotatably mounted on the first mounting rod 3, with both ends of each rotating rod 71 extending beyond the first mounting rod 3. A splicing plate 72 is fixedly connected to both ends of each rotating rod 71, and a fixing bolt 73 is screwed onto each splicing plate 72. At least two sets of fixing threaded holes 41 are provided on the second mounting rod 4, and the height of each fixing threaded hole 41 on the second mounting rod 4 corresponds one-to-one with the height of each rotating rod 71 on the first mounting rod 3. When two adjacent protective fences are spliced ​​together, the splicing plate 72 on the first mounting rod 3 of one protective fence can be rotated and connected to the fixing threaded hole 41 on the second mounting rod 4 of the other protective fence through the fixing bolt 73.

[0038] Specifically, the splicing plate 72 is a rectangular plate, and the end of the rotating rod 71 is connected to one end of the splicing plate 72 along its length. The other end of the splicing plate 72 along its length has a threaded through hole, and the fixing bolt 73 is screwed into the threaded through hole. When the protective fence is not connected to an adjacent protective fence, the end of the splicing plate 72 with the fixing bolt 73 rotates under its own weight to directly below the rotating rod 71. When it needs to be spliced ​​with an adjacent protective fence, the splicing plate 72 is rotated 90° clockwise. Figure 1 and Figure 2 Align the fixing bolts 73 on the splicing plate 72 with the fixing threaded holes 41 on the second mounting rod 4 of the adjacent protective baffle 2, and then tighten the fixing bolts 73 to connect and fix the splicing plate 72 to the second mounting rod 4. By setting the splicing plate 72 to connect adjacent protective barriers, the strength of the connection between the protective barriers is strengthened, which can reduce the risk of collision deformation and damage to the connection of the protective barriers.

[0039] Furthermore, the first mounting rod 3 is provided with a mounting groove 32, and a sliding groove 33 is provided between the mounting groove 32 and the connecting groove 31. A sealing plate 9 is slidably connected in the sliding groove 33, and the lower end of the sealing plate 9 is connected to the uppermost rotating rod 71 through an unlocking mechanism. The sealing plate 9 has a sealed state and an open state; when the uppermost splicing plate 72 is not connected to the adjacent protective fence, the upper end of the sealing plate 9 extends into the mounting groove 32 and seals the first end of the guide pipe 6, at which time the sealing plate 9 is in the sealed state; when the uppermost splicing plate 72 rotates 90° and connects to the adjacent protective fence, the rotating rod 71 fixed to the uppermost splicing plate 72 rotates, thereby driving the sealing plate 9 to move downward along the sliding groove 33 through the unlocking mechanism and no longer sealing the guide pipe 6, at which time the sealing plate 9 is in the open state. With this configuration, when the protective fence is not spliced ​​with an adjacent protective fence, the first end of the guide pipe 6 is sealed by the sealing plate 9, which is in a sealed state, to prevent water leakage; when the protective fence is spliced ​​with an adjacent protective fence, the sealing plate 9 at the first end of the guide pipe 6 automatically switches to the open state, so that the guide pipes 6 between the spliced ​​protective fences are connected, allowing water to flow normally.

[0040] Furthermore, the unlocking mechanism is a rack and pinion transmission mechanism, which includes a gear 81 and a rack 82 that mesh with each other. The gear 81 is fixedly connected to the uppermost rotating rod 71, and the rack 82 is slidably disposed on the side wall of the mounting groove 32. The lower end of the sealing plate 9 is fixedly connected to the rack 82 through a connecting plate 83. Specifically, a guide groove is provided on the side wall of the mounting groove 32, and a slider matching the guide groove is provided on one side of the rack 82. The rack 82 is slidably connected in the guide groove through the slider. When two adjacent protective barriers are spliced ​​together, the splicing plate 72 rotates 90°. The rotation of the splicing plate 72 drives the rotating rod 71 to rotate, and the rotation of the rotating rod 71 drives the gear 81 to rotate clockwise. This causes the rack 82, which meshes with the gear 81, to move downward, and causes the sealing plate 9, which is connected to the rack 82, to move downward. This causes the sealing plate 9 to contact the first end of the guide pipe 6 and automatically switch the sealing plate 9 from the sealed state to the open state.

[0041] Furthermore, a first sealing element is provided at the second end of the guide pipe 6; and / or, a second sealing element is provided at the open end of the connecting groove 31. Specifically, the first sealing element can be a shaft rubber sealing ring sleeved on the guide pipe 6, and the second sealing element can be a hole rubber sealing ring that is engaged in the sealing groove at the open end of the connecting groove 31. By providing sealing elements, it can be ensured that after adjacent protective barriers are spliced ​​together, and the second end of the guide pipe 6 is inserted into the connecting groove 31, the connection between the guide pipe 6 and the connecting groove 31 is well sealed, and no water leakage will occur.

[0042] In summary, the protective fence for construction projects provided by this utility model has a spray pipe rotatably installed on the fence frame. The spray pipe is connected to the guide pipe in the horizontal bar on the fence frame through a connecting pipe. By adjusting the angle of the spray pipe, dust can be sprayed to reduce dust at the construction site inside the fence, thus improving the dust removal effect at the construction site. When two adjacent protective fences are spliced ​​together, the second end of the guide pipe of one protective fence can be inserted into the connecting groove of the adjacent protective fence, thereby realizing the connection of the guide pipes, making installation quick and convenient.
