Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and more specifically, to a protective fence for construction engineering construction. Background Art

[0002] A protective fence refers to a kind of fence or barrier set around areas such as construction sites, event venues, or private properties. It is a measure taken to isolate the construction site from the external environment and make the construction site a relatively enclosed space, including walls built with various masonry materials, enclosures composed of various formed plates, etc.

[0003] As the core protective facility at the construction site of a building, the building protective fence plays a key role in isolating the operation area and ensuring the safety of pedestrians. With the upgrading of environmental protection requirements, the control of construction dust has become a mandatory specification. The traditional method is to separately install a fog cannon vehicle or a spray tower outside the fence. However, this kind of dust reduction method occupies a large area, and multiple fog cannon vehicles or multiple sets of spray towers need to be set up to cover the entire construction site, and the construction cost is relatively high. Although there is currently a solution of hanging a spray pipe on the protective fence, which realizes the physical combination of the protective fence and the dust reduction function, the spray pipes cannot be directly connected during the splicing of the fences, and the spray pipes need to be separately connected to each fence, resulting in inconvenience in use. Moreover, the spray pipes hung on the protective fence cannot adjust the spraying angle, and the dust reduction effect is poor. Summary of the Invention

Detailed implementation manners

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

[0032] The present invention provides a protective retaining fence for construction engineering construction. Refer to Figures 1 to 3 , the protective retaining fence for construction engineering construction includes a retaining fence frame 1, a baffle 2 and a spray pipe 5; wherein, the retaining fence frame 1 includes an upper cross bar 11 and a lower cross bar 12 arranged in parallel, and a plurality of vertical bars 13 connected between the upper cross bar 11 and the lower cross bar 12; the two ends of the retaining fence frame 1 are respectively vertically provided with a first mounting rod 3 and a second mounting rod 4; the baffle 2 is connected to the retaining fence frame 1; the spray pipe 5 is rotatably arranged at the top of the retaining fence frame 1, and a plurality of nozzles 51 are arranged on the spray pipe 5, a diversion pipe 6 is arranged in the upper cross bar 11, and the spray pipe 5 is connected to the diversion pipe 6 in the upper cross bar 11 through a connecting pipe 52; a connecting groove 31 is arranged at the upper end of the first mounting rod 3, the connecting groove 31 is communicated with the first end of the diversion pipe 6 in the upper cross bar 11, the second end of the diversion pipe 6 extends a preset length outside the second mounting rod 4, and the second end of the diversion pipe 6 is adapted to the opening of the connecting groove 31.

[0033] Specifically, the upper and lower ends of the vertical bar 13 can be connected to the upper cross bar 11 and the lower cross bar 12 by welding. In this embodiment, the retaining fence frame 1 includes two vertical bars 13, and the two vertical bars 13 are respectively symmetrically arranged on both sides of the middle position of the upper cross bar 11. The first mounting rod 3 and the second mounting rod 4 are fixedly connected to both sides of the retaining fence frame 1 by welding, and both the first mounting rod 3 and the second mounting rod 4 are perpendicular to the upper cross bar 11 and the lower cross bar 12. During specific implementation, anchor plates can be arranged at the bottoms of the first mounting rod 3 and the second mounting rod 4 for anchoring and connecting the first mounting rod 3 and the second mounting rod 4 to the ground through anchor bolts.

[0034] When multiple protective fences for building construction are spliced to enclose the construction site, the second end of the diversion pipe 6 of one protective fence can be inserted into the connecting groove 31 of the adjacent protective fence, so that the diversion pipes 6 of all the protective fences can be connected together. After splicing, only one water inlet pipe needs to be connected to supply water to the spray pipes 5 of all the spliced protective fences. The construction site is sprayed and dust is reduced through the nozzles 51 on the spray pipes 5, greatly improving the dust removal effect of the construction site.

[0035] As Figure 1 and Figure 2 shown, two fixing blocks 111 are arranged at intervals on the top of the fence frame 1, and both ends of the spray pipe 5 are rotatably connected to the fixing blocks 111. Specifically, circular through holes are formed in the fixing blocks 111, and both ends of the spray pipe 5 are rotatably arranged in the circular through holes; a locking member is arranged on one of the fixing blocks 111 for locking and fixing the spray pipe 5. In this embodiment, the locking member is a locking bolt 112. A threaded through hole communicating with the circular through hole is formed in one of the fixing blocks 111, and the locking bolt 112 is screwed into the threaded through hole. The spray pipe 5 can be locked and fixed by screwing the locking bolt 112. A hand crank 53 is arranged at one end of the spray pipe 5, and the other end of the spray pipe 5 is communicated with the diversion pipe 6 through the connecting pipe 52. The spray pipe 5 and the connecting pipe 52 are connected through a rotary joint. By rotatably connecting the spray pipe 5 to the top of the fence frame 1, the spray pipe 5 can be conveniently rotated through the hand crank 53 to adjust the angle of the nozzles 51 on the spray pipe 5 for spray dust reduction at different angles according to the specific situation of the construction site.

[0036] Preferably, a ball valve (not shown in the figure) can be arranged on the connecting pipe 52 to supply water to the spray pipe 5 by opening the ball valves on the connecting pipes 52 of one or more protective fences according to the site conditions, so as to realize spray dust removal in a local area of the construction site.

[0037] Furthermore, at least two rotating rods 71 are rotatably arranged on the first mounting rod 3. Both ends of each rotating rod 71 extend out of the first mounting rod 3, and a splicing plate 72 is fixedly connected to both ends of each rotating rod 71. A fixing bolt 73 is screwed on each splicing plate 72; at least two groups of fixing threaded holes 41 are arranged on the second mounting rod 4. The heights of the fixing threaded holes 41 on the second mounting rod 4 correspond to the heights of the rotating rods 71 on the first mounting rod 3 one by one; when two adjacent protective fences are spliced, the splicing plate 72 on the first mounting rod 3 of one protective fence can be rotated and then 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. The end of the rotating rod 71 is connected to one end of the splicing plate 72 in the length direction. A threaded through hole is provided at the other end of the splicing plate 72 in the length direction, and the fixing bolt 73 is screwed onto 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 screwed thereon rotates to directly below the rotating rod 71 under the action of its own gravity. When it is necessary to be spliced with an adjacent protective fence, rotate the splicing plate 72 clockwise by 90°( Figure 1 and Figure 2 direction), so that the fixing bolt 73 on the splicing plate 72 is aligned with the fixing threaded hole 41 on the second mounting rod 4 of the adjacent protective baffle 2, and then screw the fixing bolt 73 to realize the connection and fixation of the splicing plate 72 and the second mounting rod 4. By providing the splicing plate 72 to connect adjacent protective fences, the strength of the connection between the protective fences is enhanced, and the risk of collision deformation and damage at the connection of the protective fences can be reduced.

[0039] Furthermore, an installation groove 32 is provided inside the first mounting rod 3. A sliding groove 33 is provided between the installation groove 32 and the connection groove 31. A sealing plate 9 is slidably connected in the sliding groove 33. 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 sealing state and an open state; when the uppermost splicing plate 72 is not connected to an adjacent protective fence, the upper end of the sealing plate 9 extends into the installation groove 32 to block the first end of the diversion pipe 6, and at this time the sealing plate 9 is in the sealing state; when the uppermost splicing plate 72 rotates 90° to be connected to an adjacent protective fence, the rotating rod 71 fixedly connected to the uppermost splicing plate 72 rotates, and then drives the sealing plate 9 to move downward along the sliding groove 33 through the unlocking mechanism and no longer block the diversion pipe 6. At this time, the sealing plate 9 is in the open state. With such a setting, when the protective fence is not spliced with an adjacent protective fence, the first end of the diversion pipe 6 is blocked by the sealing plate 9 in the sealing 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 diversion pipe 6 automatically switches to the open state, so that the diversion pipes 6 between the spliced protective fences are connected, and the water can flow normally.

[0040] Furthermore, the unlocking mechanism is a gear-rack transmission mechanism. The gear-rack transmission mechanism includes a gear 81 and a rack 82 that mesh and drive each other. The gear 81 is fixedly connected to the uppermost rotating rod 71. The rack 82 is slidably arranged on the side wall of the installation groove 32. The lower end of the blocking plate 9 is fixedly connected to the rack 82 through a connecting plate 83. Specifically, a guiding groove is formed on the side wall of the installation groove 32. A slider that matches the guiding groove is arranged on one side of the rack 82. The rack 82 is slidably connected to the guiding groove through the slider. When two adjacent protective enclosures are spliced, the splicing plate 72 rotates 90°. The rotation of the splicing plate 72 drives the rotation of the rotating rod 71. The rotation of the rotating rod 71 drives the gear 81 to rotate clockwise, thereby driving the rack 82 engaged with the gear 81 to move downward, driving the blocking plate 9 connected to the rack 82 to move downward, so as to release the blocking of the first end of the diversion pipe 6 by the blocking plate 9, and automatically switch the blocking plate 9 from the blocking state to the open state.

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

[0042] In summary, for the protective enclosure for construction projects provided by the present invention, a spray pipe is rotatably arranged on the enclosure frame, and the spray pipe is communicated with the diversion pipe in the cross bar on the enclosure frame through a connecting pipe, which can spray and dust the construction site inside the enclosure by adjusting the angle of the spray pipe, improving the dust removal effect on the construction site; when two adjacent protective enclosures are spliced, the second end of the diversion pipe of one of the protective enclosures can be inserted into the connection groove of the adjacent protective enclosure, thereby realizing the connection of the diversion pipes, and the installation is quick and convenient.
