Description

Technical Field

[0001] The utility model relates to the application field of sound insulation rolling curtains in building construction, in particular to a noise reduction and isolation device for green building construction. Background Art

[0002] In the construction requirements, the construction site needs to install soundproof roller shutters on the periphery to reduce the noise of the construction site. The soundproof roller shutters are mainly made of sound-absorbing and sound-insulating foam boards and damping sound-insulating felts, which have the advantages of being waterproof, moisture-proof and easy to clean.

[0003] Soundproof roller shutters are usually made up of multiple pieces spliced ​​together using Velcro, and are fixed to a metal frame using cable ties to form a wall that can block noise. The metal frame that fixes the soundproof roller shutter can be customized as needed.

[0004] The soundproof roller shutter is usually green and has a certain weight, which makes it difficult to manually bind the soundproof roller shutter to the metal frame using cable ties. Two people are required to work together, one to stabilize the soundproof roller shutter and the other to bind it with cable ties. In addition, in some construction sites, as the height of the building increases, the soundproof roller shutter needs to rise with the building. When the installation height of the soundproof roller shutter is high, workers need to climb to the scaffolding outside the building to bind the soundproof roller shutter. Working at high altitude is a very dangerous job. Utility Model Content

[0049] The working principle of the utility model is as follows: firstly, the traction device 2 is installed to the top of the metal frame 1, the nut 218 is loosened and removed, the first threaded rod 211 is kept in a vertical state, and then the traction device 2 is engaged with the metal frame 1, and then the second threaded rod 213 is screwed, because the second threaded rod 213 is rotatably connected with the second fixing block 212, and the second threaded rod 213 is threadedly connected with the first fixing block 210, rotating the second threaded rod 213 will shorten the distance between the second fixing block 212 and the first fixing block 210, thereby clamping the metal frame 1, during the rotation of the second threaded rod 213, the spring 214 will be compressed, and the limiting block 215 at the top of the second fixing block 212 slides in the limiting groove 216, and then the first threaded rod 211 is rotated to engage with the second fixing block 212, and the nut 218 is used to be screwed to the outside of the first threaded rod 211 to clamp the metal frame 1, and the linkage block 217 can prevent the nut 218 and the first threaded rod 211 from slipping off.

[0050] Use the turning handle to rotate the protrusion 209 to drive the worm 208 to rotate, thereby driving the worm wheel 207 to rotate, that is, driving the drum 202 to rotate, so that the wound wire rope 205 is loosened. When the wire rope 205 is loosened to a certain extent, the second buckle 206 at the end of the wire rope 205 is engaged with the inside of the first buckle 4, and then the turning handle is used to reversely rotate the protrusion 209 to shrink the wire rope 205, so as to pull up the soundproof roller curtain 3. After the soundproof roller curtain 3 is pulled to a suitable height, the soundproof roller curtain 3 is bound with a cable tie. According to the above steps, multiple groups of soundproof roller curtains 3 can be installed, and each group of soundproof roller curtains 3 is adhered with Velcro on the side. When there is construction noise at the construction site, the sound-absorbing and sound-insulating foam board and the damping sound-insulating felt inside the soundproof roller curtain 3 can reduce the noise generated during construction work, which can be reduced by about 30 decibels.
