Description

[Technical field]

[0001] The utility model relates to the technical field of sound absorbing materials, in particular to a fast-joined sound absorbing body. [Background technology]

[0002] Sound absorbers are sound absorbing components that are suspended in the upper part of the building space to reduce indoor noise or improve indoor sound quality. Space sound absorbers have the characteristics of less material, light weight, low investment, high sound absorption efficiency, flexible layout and convenient construction.

[0003] Many countries have started using space sound absorbers since the 1950s, and their application became more widespread in the 1970s. China began to use them in the 1970s. Their application increased in the 1980s. Space sound absorbers can be in various shapes, such as plates, blocks, columns, cones, and spheres, depending on the use, area, floor height, structural form, decoration requirements, and sound source characteristics of the building.

[0004] Spatial sound absorbers are mostly used in indoor gymnasiums. Their various shapes and arrangements can enhance the indoor decorative effect. The most important thing is their sound-absorbing performance, which can prevent echo defects in large halls and effectively reduce reverberation time.

[0005] At present, most of the square, cylindrical, conical and spherical sound absorbers are connected by glue, which has the following defects: 1. With the extension of the use time, the glue will be debonded, affecting the use effect of the sound absorber. 2. The three-dimensional sound absorber is not convenient to transport. 3. The use of glue will cause environmental problems. [Contents of the utility model]

[0006] In order to solve the above problems, the purpose of the utility model is to provide a quick-joined sound-absorbing body that can connect panels without glue.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a quickly spliced ​​sound-absorbing body, including a closing plate and two end plates, the closing plate is provided with multiple folds along the vertical direction, and the closing plate can be enclosed into a three-dimensional structure after being bent along the folds, and the two end plates are arranged at both ends of the three-dimensional structure to close the three-dimensional structure; the closing plate is provided with a serrated structure around it, and the two end plates are also provided with a serrated structure around them, and they are fitted together through the serrated structure when enclosed.

[0008] A quick-joined sound-absorbing body in the utility model is further configured as follows: the enclosing plate is provided with three folds in the vertical direction, and the enclosing plate can be enclosed into a rectangular body after being bent along the folds.

[0009] A quick-joined sound-absorbing body in the utility model is further configured as follows: the end plate is a square structure, and is covered with two ends of a rectangular body enclosed by the enclosing plate through a sawtooth structure to close the two ends of the rectangular body.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the above-mentioned quick-joined sound absorber adopts a zigzag joint structure to achieve the connection between the panels, replacing the original glue connection method, and there will be no debonding phenomenon, ensuring the use effect of the sound absorber. Moreover, the panels can be transported to the site for quick jointing, which will not occupy the transportation space. There will also be no environmental problems caused by the use of glue.

[0014] The following is a further detailed description of a quick-joined sound-absorbing body of the present invention through specific embodiments.

[0015] like Figure 1 , Figure 2 As shown, a quick-joined sound-absorbing body comprises an enclosure panel 1 and two end panels 2, wherein the enclosure panel 1 is provided with a plurality of folds 3 in the vertical direction, and the enclosure panel 1 can be enclosed into a three-dimensional structure after being bent along the folds 3, and the two end panels 2 are arranged at both ends of the three-dimensional structure to close the three-dimensional structure; the enclosure panel 1 is provided with a serrated structure 4 all around, and the two end panels 2 are also provided with a serrated structure 4 all around, and the serrated structures 4 are used to fit together when enclosed.

[0016] In this embodiment, the enclosure plate 1 is vertically provided with three folds 3, and the enclosure plate 1 can be enclosed into a rectangular body after being bent along the folds 3. The end plate 2 is a square structure, and is covered with the two ends of the rectangular body enclosed by the enclosure plate 1 through the sawtooth structure 4 to close the two ends of the rectangular body.

[0017] There may also be multiple folds 3 in the enclosure panel 1, which, after being enclosed, form three-dimensional structures of different structures, all of which fall within the protection scope of the present utility model.

[0018] The above-mentioned quick-joined sound-absorbing body adopts a zigzag joint structure to achieve the connection between the panels, replacing the original glue connection method, and there will be no debonding phenomenon, ensuring the use effect of the sound-absorbing body. In addition, the panels can be transported to the site for quick jointing, which will not occupy the transportation space. There will also be no environmental problems caused by the use of glue.
