Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a noise reduction device for green building construction. Background Technology

[0002] Green buildings are high-quality buildings that achieve energy conservation and emission reduction. Throughout their entire life cycle, they save resources, protect the environment, and provide people with healthy, suitable, and efficient living spaces, maximizing the harmonious coexistence of humans and nature. Construction workers often need to cut or weld different materials to meet the needs of construction. During cutting or welding operations, machines often generate significant noise. Therefore, noise reduction devices are needed to specifically isolate and reduce noise at the construction site to prevent noise from affecting the work and lives of surrounding residents.

[0003] Traditional noise reduction devices are often temporarily constructed from several soundproof panels. Although they can perform sound insulation, the assembly of these devices is time-consuming and labor-intensive, affecting construction efficiency. They are also inconvenient to store and reuse. To avoid such problems, a green building construction noise reduction device is proposed to solve the existing issues. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1-6 This utility model provides a technical solution: a noise reduction device for green building construction, including a sound insulation main board 1. Two sound insulation main boards 1 are symmetrically arranged at the front and back. First corner plates 2 are fixedly connected to both sides of the top and bottom of the sound insulation main board 1. Ball bearings 19 are provided on both sides of the bottom of the sound insulation main board 1. Threaded sleeves 20 are fixedly connected to the surface of the sound insulation main board 1. A threaded rod 21 with a handle is connected to the internal thread of the threaded sleeve 20. A sound insulation top plate 22 is installed on the rear side of the rear sound insulation main board 1 by bolts. Pins 23 are fixedly connected to both sides of the top of the sound insulation main board 1. The surface of the sound insulation top plate 22 has insertion holes 24 that match the pins 23. As a detailed explanation: the sound insulation main board 1, the sound insulation side plates 3, and the sound insulation top plate 22 are all medium density fiberboard. The advantages of medium density fiberboard are that it is easy to process, moisture-proof, fire-resistant, sound-insulating, and heat-insulating.

[0022] Furthermore, to facilitate the unfolding and fixing of the device, a soundproof side plate 3 is rotatably connected between the two first corner plates 2 on the same side, and a second corner plate 4 is rotatably connected between the two soundproof side plates 3 on the same side. Two second corner plates 4 are symmetrically arranged on the same side. A threaded post 5 is fixedly connected to one side of the soundproof side plate 3. An arc-shaped receiving groove 7 matching the threaded post 5 is opened on the front side of the soundproof main plate 1. A nut 6 matching the arc-shaped receiving groove 7 is threadedly connected to the surface of the threaded post 5.

[0023] Furthermore, to facilitate folding and limiting of the device, mounting plates 8 are fixedly connected to both sides of the soundproof main board 1. Sliding sleeves 9 are fixedly connected to the opposite side of the two mounting plates 8 on the same side, and the two sliding sleeves 9 are staggered vertically. The top and bottom of the sliding sleeves 9 are slidably connected to the locking blocks 10, and one end of the locking blocks 10 extends into the interior of the sliding sleeves 9. Insert blocks 11 are fixedly connected to the opposite side of the two mounting plates 8 on the same side, and the two insert blocks 11 are staggered vertically. The top and bottom of the insert blocks 11 are provided with locking slots 12 that are used in conjunction with the locking blocks 10. A rotating rod 13 is rotatably connected to one side of the locking blocks 10. A sliding groove plate 14 is fixedly connected to one side of the sliding sleeves 9. A triangular plate 15 is slidably connected inside the sliding groove plate 14. A first return spring 16 is fixedly connected between the triangular plate 15 and the sliding groove plate 14. A gripping frame 17 is fixedly connected to one side of the triangular plate 15. A semi-circular grip 18 that is used in conjunction with the gripping frame 17 is fixedly connected to one side of the mounting plate 8.

[0024] As a detailed explanation, the surface of the card block 10 is provided with a sliding groove 25, and the top and bottom of the sliding sleeve 9 are fixedly connected with L-shaped sliding plates 26 that are adapted to slide in the sliding groove 25. A second return spring 27 is fixedly connected between the L-shaped sliding plate 26 and the sliding groove 25.

[0025] When using the extended version, the operator firmly grips the holding frame 17 and the semi-circular handle 18, causing the holding frame 17 to enter the semi-circular handle 18. The movement of the holding frame 17 causes the triangular plate 15 to press against the rotating rod 13, causing the locking block 10 and the locking slot 12 to disengage from their limits. Then, the two soundproof main plates 1 are pulled in the opposite direction, causing the soundproof main plates 1 to rotate using the first corner plate 2 and the second corner plate 4 as the rotation medium, causing the soundproof side plates 3 to unfold, forming a rectangular space. The two soundproof side plates 3 on the same side will eventually unfold at a 90-degree angle with the adjacent soundproof main plates 1. As the soundproof side plates 3 unfold, the threaded post 5 rotates into the arc-shaped receiving groove 7. Then, the nut 6 is tightened to secure it to the surface of the soundproof main plate 1. Then, the bolts are removed to remove the soundproof top plate 22, and the soundproof top plate 22 is assembled to the top of the device by the engagement of the pin 23 and the socket 24.
