Embodiment 1

[0037] see Figure 1-7 A noise reduction barrier for municipal road bridge construction, comprising a body 1, a plurality of connecting grooves 2 are provided on one side of the body 1, and connecting blocks 3 matching the connecting grooves 2 are connected on the other side;

[0038] The middle part of the connection groove 2 is provided with a connection plate 4, the connection plate 4 is fixedly connected to the inner wall of the connection groove 2, and the upper and lower surfaces of the connection plate 4 are provided with a connection groove 5;

[0039] One end of the connecting block 3 is fixedly connected to the body 1, and the other end is provided with a first groove 301, and an inverted trapezoidal lifting block 302 matching the connecting groove 5 is arranged in the first groove 301, and the lifting block 302 A first spring 303 is fixedly connected between the top end and the first groove 301 , and the side of the lifting block 302 away from the body 1 is an inver...

Embodiment 2

[0043] Such as figure 2 As shown, the middle part of the body 1 is a light steel keel 101, the left side of the light steel keel 101 is a sound insulation felt 102 and a sound insulation board 103, and the right side is a sound-absorbing cotton 104 and a calcium silicate composite sound-absorbing board 105 in turn.

[0044] Sound insulation felt 102 is a high-density coil with certain flexibility, which has good sound insulation effect;

[0045] The sound insulation board 103 is a plate that acts on the sound insulation effect. Because the present invention mainly acts on the sound in the air, the sound insulation board of the present invention adopts an air sound insulation board, that is, the plate that blocks the sound transmitted in the air, and the effect is obvious;

[0046] The sound-absorbing cotton 104 has a sound-absorbing effect, that is to say, it converts sound energy into heat energy, and the sound-absorbing material does block the transmission of sound. The so...

Embodiment 3

[0049] Such as Figure 3-5 As shown, the bottom of the connecting groove 5 is provided with a second groove 601, and a first flexible air bag 602 is arranged in the second groove 601, and the bottom end of the first flexible air bag 602 is fixedly connected with the bottom of the second groove 601, and the first The top of the telescopic airbag 602 is fixedly connected to the push plate 603 at the bottom of the connection groove 5, and the first telescopic airbag 602 is provided with a second spring 604;

[0050] The side wall of the connection groove 5 away from the connection block 3 is provided with a third groove 701, and a second telescopic air bag 702 and a push rod 703 are arranged in the third groove 701, and one end of the second telescopic air bag 702 is away from the connection groove 5 and The third groove 701 is fixedly connected, and one end close to the connecting groove 5 is fixedly connected with one end of the push rod 703, and a third spring 704 is arranged ...

Abstract

The invention discloses a noise reduction barrier for municipal road and bridge construction, which comprises a body, one side of the body is provided with several connecting grooves, and the other side is connected with connecting blocks matching the connecting grooves; the middle part of the connecting groove A connection plate is provided, and the connection plate is fixedly connected with the inner wall of the connection groove, and the upper and lower surfaces of the connection plate are provided with connection grooves; one end of the connection block is fixedly connected with the body, and the other end is provided with a first groove, the first groove An inverted trapezoidal lifting block matching the connection groove is arranged inside, and a first spring is fixedly connected between the top of the lifting block and the first groove, and the side of the lifting block away from the body is an inverted trapezoidal Inclined surface; the present invention uses light steel keel as support, calcium silicate composite sound-absorbing board and sound-absorbing cotton for sound absorption, and then sound insulation and noise reduction for sound insulation board and sound insulation felt, so that the noise generated during construction can be greatly reduced.

Description

technical field [0001] The invention relates to the field of municipal administration, and more specifically relates to a noise reduction barrier for construction of municipal roads and bridges. Background technique [0002] During the construction of municipal roads and bridges, it is necessary to use barriers to enclose the construction area, and some roads and bridges are relatively close to people's residences, and the noise generated during construction will be relatively large, so noise reduction is required; [0003] On the one hand, the existing barriers have poor noise reduction and sound absorption functions. On the other hand, when they are installed and connected, there is a large gap between them and the installation is cumbersome, which leads to a greatly reduced noise reduction performance, and the efficiency of the barrier is slow. , affecting the construction progress. Contents of the invention [0004] 1. technical problem to be solved [0005] Aiming ...
