Problems solved by technology

However, the installation of existing suspended ceilings and mineral wool sound-absorbing materials is relatively cumbersome. At the same time, with the extension of use time, the mineral wool sound-absorbing materials are easy to fall off from the gaps in the suspended ceiling and other positions.
As a result, it will cause indoor environment pollution, affect human health, and also reduce the sound absorption effect.

Embodiment 1

[0072] Such as figure 1 and Figure 4 As shown, in the embodiment, the keel assembly 10 includes a flat first partition 121 . The first partition 121 is extended along the length direction of the keel body 11 , the first partition 121 is perpendicular to the keel body 11 , and the first partition 121 is parallel to the first panel 21 . One side of the first partition 121 can be connected with the keel body 11 , and the other side of the first partition 121 can be connected with the second panel 22 . The first partition 121 can divide the cavity separating the inside of the perforated square space sound absorber into two sub-cavities, one of which is close to the first panel 21 , and the other is close to the third panel 23 . In some specific embodiments, the length of the first partition 121 may be equal to the length of the keel body 11 .

[0073]In the embodiment, a pair of symmetrical limiting plates 115 are provided on the side of the keel body 11 close to the square ch...

Embodiment 2

[0078] Such as Figure 5 As shown, the keel assembly 10 includes three flat second partitions 122 . The three second partitions 122 are spaced apart from each other and arranged in parallel. In some specific embodiments, the second partition 122 is perpendicular to the keel body 11 and the first panel 21 at the same time. Meanwhile, one side of the second partition 122 can be connected to the keel body 11 , and the other three sides of the second panel 22 can be respectively connected to the first panel 21 , the second panel 22 and the third panel 23 at corresponding positions. Correspondingly, the three second partitions 122 can divide the perforated rectangular sound absorbing body into four sub-cavities.

[0079] In some other embodiments, the position between the first partition 121 and the keel body 11 may also be non-perpendicular.

[0080] In the embodiment, corresponding to the position of any sub-cavity, a slit 30 is provided on the first panel 21 for connecting th...

Embodiment 3

[0084] Such as Figure 6 As shown, in some embodiments, the keel assembly 10 includes a third partition 123 with a U-shaped cross section. The shape of the third partition 123 can be substantially the same as that of the square channel assembly 20. One side of the plate 123 can also be provided with an opening structure, wherein the cross section of the third partition 123 can be seen as the cross section of the third partition 123 on the y-z plane. It can be understood that the cross-sectional size of the third separator 123 on the y-z plane may be smaller than the cross-sectional size of the square channel assembly 20 on the y-z plane.

[0085] In an embodiment, a pair of symmetrical limiting plates 115 is provided on the side of the keel body 11 close to the square channel assembly 20 , and the third partition 123 can be provided at the positions of the two limiting plates 115 . The two limiting plates 115 can be inserted into the openings of the third partition 123 and ca...

Abstract

The invention discloses a partition perforated square tube space sound absorber, and relates to the technical field of building material decoration. The partition perforated square tube space sound absorber comprises a keel assembly and a square tube assembly, the keel assembly comprises a keel body, a pair of symmetrical limiting protruding strips are arranged on one side of the keel body, the two limiting protruding strips are close to the two side edges of the keel body respectively, and the two limiting protruding lines are matched with the keel body to form two mounting grooves; and the square tube assembly covers the keel assembly, a pair of opposite connecting plates is arranged on the side, close to the keel assembly, of the square tube assembly, the two connecting plates and the two mounting grooves are mounted in a one-to-one correspondence mode, and at least one gap is formed in the square tube assembly, so that the partition perforated square tube space sound absorber forms a Helmholtz resonator. The partition perforated square tube space sound absorber can realize a good sound absorption effect, and can also avoid pollution to an indoor environment.

Description

technical field [0001] The application relates to the technical field of building material decoration, in particular to a sound-absorbing body of a partitioned perforated square space. Background technique [0002] For shopping malls, leisure places, airports, high-speed rail stations and other places, there is usually serious noise pollution. [0003] In the prior art, for places with serious noise pollution, the ceiling of the building is usually filled with mineral wool sound-absorbing materials to absorb noise, so as to achieve the effect of noise reduction. However, the installation of existing suspended ceilings and mineral wool sound-absorbing materials is relatively cumbersome, and at the same time, with the prolongation of use time, the mineral wool sound-absorbing materials are easy to fall off from positions such as gaps in the suspended ceiling. As a result, it will cause pollution of the indoor environment, affect human health, and also reduce the sound absorpt...
