[0019] The combined construction noise reduction device proposed by the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the utility model will become clearer according to the following description. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

[0020] Embodiment 1

[0021] Please refer to Figures 1 to 4 , the structural composition of the combined construction noise reducing device of the utility model is described in detail.

[0022] refer to Figures 1 to 4A combined construction noise reduction device includes a combined sound-absorbing panel arranged on a site fence 7, the combined sound-absorbing panel includes a plurality of sound-absorbing panel units connected in sequence by yin-yang type lock buckles 1, and the bottom end of the sound-absorbing panel unit is fixedly connected to the site fence 7 by an expansion screw 8; the sound-absorbing panel unit includes a sound-absorbing panel 2, sound-absorbing cotton 4 and a connecting frame 3, the sound-absorbing cotton 2 is filled in a cavity formed by overlapping and splicing two sound-absorbing panels 2, and is sealed by an aluminum plate 5, and a connecting frame 3 is arranged around the sound-absorbing panel 2.

[0023] Specifically, two sound-absorbing panels 2 are overlapped and spliced ​​to form a cavity, and sound-absorbing cotton 4 is filled in the cavity, so as to ensure that the combined sound-absorbing panel has excellent sound absorption performance. Each sound-absorbing panel 2 is matched with one side of sound-absorbing cotton 4. After the two sound-absorbing panels 2 are overlapped and fixed, the effect of double-sided sound-absorbing cotton is formed, and the aluminum plate 5 is welded and sealed, which improves the service life of the combined sound-absorbing panel and increases the number of turnover uses. In addition, the adjacent two sound-absorbing panels 2 are connected and fixed by the yin-yang lock 1, which is convenient for installation and disassembly and prolongs the service life.

[0024] In this embodiment, more preferably, the male-female lock buckle 1 includes a concave side lock buckle and a convex side lock buckle respectively arranged in the grooves 6 of the connecting frame of two adjacent sound absorbing panel units, so that the male-female lock buckle 1 is connected to form a closed whole.

[0025] In this embodiment, more preferably, the groove width of the connecting frame for installing the convex side lock is slightly larger than the groove width of the connecting frame for installing the concave side lock, so as to facilitate the installation and disassembly of the sound absorbing panel 2 and the connection and fixation of the yin-yang type lock 1.

[0026] In this embodiment, more preferably, the sound absorbing panel unit is fixed to the on-site enclosure 7 around the construction site by a fixing bracket.

[0027] In this embodiment, more preferably, in order to facilitate material acquisition and save costs, the connection frame 3 is made of square steel. Figures 1 to 4 This embodiment also provides an installation method of the combined construction noise reduction device, which includes the following steps:

[0028] The first step is to fill and weld the sound-absorbing panel 2, the sound-absorbing cotton 4, and the aluminum plate 5 according to the design requirements at the construction site to assemble a single sound-absorbing panel unit.
