[0002] Perforated mesh refers to holes of different shapes punched on the same material to meet different needs. It can be used as an environmental noise control barrier in transportation and municipal facilities such as highways, railways, subways, etc. that pass through urban areas. It is a sound-absorbing panel for sound insulation and noise reduction.

[0003] In construction projects, perforated mesh can not only be used to absorb sound and reduce noise, but also play a role in safety protection at the periphery, so it has been widely used. When installed on the periphery of the scaffolding, the perforated mesh has no reliable connection points and poor stability, which can easily cause injuries caused by falling objects from high altitudes.

[0004] For example, announcement number CN218149709U discloses a connection device for fixing a perforated protective net, which establishes a reliable and effective connection between the perforated protective net and the scaffolding, ensures the safety of the construction site, and reduces the probability of accidents such as falling objects or mechanical strikes.

[0005] However, when the overall scaffolding outer frame is an arc-shaped facade, the perforated mesh is often not tightly fitted due to the angle when directly spliced, affecting the overall appearance of the building's outer surface. There is no special connection device on the market, which is difficult to adapt to the fixing requirements of the arc-shaped facade. In order to ensure the safety of the outer frame construction and the quality of the forming, a standardized fixing device for the perforated mesh of the outer scaffolding is provided.

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment one:

[0033] See also Figure 1-2 As shown, the utility model is a fixed device for fixing a punched mesh of an external scaffold, comprising a connecting steel pipe 4, a steel plate connector 2 and a locking device, wherein:

[0034] The connecting steel pipe 4 is used to connect to the scaffolding;

[0035] The steel plate connector 2 includes a clamping portion 21 and a connecting portion 22. The clamping portion 21 has two clamping interfaces, and the two clamping interfaces are arranged in corresponding positions and with opposite opening directions, and are used to clamp adjacent punching meshes.

[0036] One end of the clamping portion 21 is fixedly connected to a connecting portion 22 . The connecting portion 22 can move along the axis of the connecting steel pipe 4 . The locking device is used to lock the position of the connecting portion 22 relative to the connecting steel pipe 4 .

[0037] The working principle is: when the overall curved scaffolding facade is required, the connecting steel pipe 4 is fastened to the scaffolding, and the scaffolding includes a scaffolding horizontal rod 6 and a scaffolding vertical rod 7. The scaffolding horizontal rod 6 and the scaffolding vertical rod 7 are both cylindrical rods in the disc-type scaffolding system, and the diameters of the scaffolding longitudinal horizontal rod and the scaffolding vertical rod 7 are the same. The structure of the scaffolding and the method of locking the steel pipe to the scaffolding are both existing technologies, and the perforated mesh is surrounded by a perforated mesh outer frame 1. For the curved scaffolding facade, although the perforated mesh is roughly parallel to the scaffolding horizontal rod 6 at the corresponding position, due to the fixed size of the perforated mesh, it is difficult to ensure that the perforated mesh can always be fixed at a distance from the outermost scaffolding horizontal rod 6, and it is easy to exceed the connection range of the connecting steel pipe 4. In order to adapt to the limit distance of the connecting steel pipe 4, the problem of loose connection between the perforated meshes is caused.

[0038] The scaffolding horizontal rod 6 is fixedly connected to the tail of the connecting steel pipe 4 through the steel pipe fastener 5. When in use, two perforated meshes are set so that the two perforated meshes are symmetrically arranged up and down. The two perforated meshes symmetrically arranged up and down are connected through a steel plate connector 2. The perforated mesh outer frames 1 of the upper and lower perforated meshes are respectively clamped into the two clamping interfaces of the clamping part 21. The position of the connecting part 22 relative to the connecting steel pipe 4 is locked by a locking device, so that the length of the steel plate connector 2 is flexibly adjustable and can adapt to the conflict between the straight scaffolding and the curved facade. The raw materials of the device are common on the construction site and can be directly used after simple assembly or modification. It has a simple structure, easy operation, safety and reliability, and saves costs. Specific embodiment 2

[0040] See also Figure 1-2 As shown, based on the specific embodiment 1, a locking device is required to lock the position of the connecting part 22 relative to the connecting steel pipe 4. In order to save costs, the locking device is a bolt 3, and the connecting steel pipe 4 is provided with a connecting hole. The bolt 3 locks the connecting part 22 through the connecting hole. Specific embodiment three

[0042] See also Figure 3 As shown, based on the specific embodiment 2, a connection method is provided, in which the bolt 3 is threadedly connected to the connection hole, and the bolt 3 abuts against the connection portion 22.

[0043] When in use, adjust the connection part 22 to the position of the connecting steel pipe 4, and screw the bolt 3 into the thread of the connecting hole to tighten the connection part 22 to achieve locking of the connection part 22. Specific embodiment 4

[0045] See also Figure 4 As shown, based on the specific embodiment 2, another connection method is provided, the connection part 22 is provided with multiple limiting through holes, the bolt 3 passes through the connection hole and the limiting through hole, the bolt 3 is connected with a nut, and the nut is used to fasten the bolt 3 to the connecting steel pipe 4.

[0046] When in use, adjust the connecting part 22 to the position of the connecting steel pipe 4, and use the bolt 3 to pass through the limiting through hole of the connecting part 22. Different limiting through holes can change the position of the connecting part 22 relative to the connecting steel pipe 4, and tighten the other end of the bolt 3 with the nut to prevent the bolt 3 from slipping, which can improve the stability of the connection. Specific embodiment five

[0048] See also Figure 5 As shown, in the specific embodiment four, it is difficult to change the position. When the connecting hole needs to be adjusted, the bolt 3 needs to be repeatedly disassembled and assembled, which is inconvenient to use. Therefore, based on the embodiment four, the connecting hole is a waist-shaped hole, and the waist-shaped hole is distributed along the axial direction of the connecting steel pipe 4.

[0049] When the distance is not adjusted properly for the first time and the position of the connecting part 22 relative to the connecting steel pipe 4 is needed, it is only necessary to loosen the nut and readjust the position of the bolt 3 nut and the connecting part 22. At this time, temporary distance adjustment can be achieved without changing the limiting through hole through which the bolt 3 passes, and the distance adjustment range can also be increased, making it more convenient to use. Specific embodiment six

[0051] See also Figure 6-7 As shown, in the specific embodiment 4, the connection of the single bolt 3 is not stable enough. In order to improve the stability, based on the specific embodiment 4, there are multiple connection holes, and the connection holes corresponding to the limiting through holes are all connected with bolts 3 and nuts.

[0052] During use, when the connecting portion 22 is not at the extreme distance, there are at least two corresponding connecting holes and limiting through holes. At this time, the corresponding connecting holes and limiting through holes can be connected with bolts 3 and nuts, which can further improve the connection stability.

[0053] The connecting steel pipe 4 is a 48 galvanized steel pipe.

[0054] The connecting steel pipe 4 is used to connect to the steel pipe fastener 5 on the scaffolding.

[0055] This device can be used to connect the perforated mesh very firmly and tightly. The raw materials of this device are common on construction sites and can be used directly after simple assembly or modification. It has a simple structure, easy operation, safety and reliability, saves costs, and is easy to assemble and disassemble. It can be used multiple times to achieve green construction.

[0056] The above describes some embodiments of the present invention in detail, but the contents are only preferred embodiments of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
