Embodiment 1

[0069] A single-leg slit sound-absorbing structure, comprising a plurality of slats 1 arranged in parallel and fixed on a keel 2 to form a panel 100 . A gap cavity 3 with a slit 31 outlet is formed between the slats 1 , the slat 1 includes a bar body 11 and a fixed leg 12 arranged on one side of the bar body 11 , each slat 1 Only a single fixing leg 12 is provided, which is used for fixed mounting of the slats 1 . The fixing leg 12 extends along the length direction of the slat 1 , and the end of the fixing leg 12 is provided with a fixing part 121 , and the fixing part 121 is made of ductile material. The lath 1 is aluminum alloy, and the keel 2 is alloy steel. The keel 2 has a simple structure and low cost, and is suitable as a fixed base for the slat 1 .

[0070] Sockets 21 are arranged on the keel 2 , and the fixed legs 12 are engaged with the sockets 21 . The cross section of the slat 1 is I-shaped, and the cross section of the fixing part 121 is trapezoidal in shape. ...

Embodiment 2

[0096] The difference between embodiment 2 and embodiment 1 is that the gap between the strip main bodies 11 of the adjacent slats 1 is 2mm. The area of ​​the slit 31 accounts for 9.1% of the area of ​​the entire panel 100

Embodiment 3

[0098] The difference between embodiment 3 and embodiment 2 is that the sound-absorbing layer 4 of glass wool with a thickness of 50 mm on the back is removed.

Abstract

The invention relates to a single-legged strip seam sound absorption structure. The sound absorption structure comprises a panel formed by parallel arrangement of a plurality of plate strips, gap cavities with slit outlets are formed between the plate strips, fixed legs are arranged on one sides of the plate strips, and the fixed legs are used for fixing and mounting the plate strips. According tothe single-legged strip seam sound absorption structure, the strip seam sound absorption structure of the single fixed leg improves the sound absorption efficiency, meanwhile, the use amount of materials is reduced, and the production cost is reduced; due to the arrangement of the single fixed leg, so that the width of the gap cavities is increased, the collision and the friction probability of incident sound waves in a sound absorption cavity become larger, the dissipation of the sound waves is increased, the gap cavities form a Helmholtz perforated resonator and a resistant muffler at the same time, and the sound absorption effect is enhanced; the single fixed leg acts as a fixing foundation for the plate strips, the sound absorption structure does not form a strong limitation on the vibration of the plate strips under the influence of the incident sound waves, and the energy of the incident sound waves is facilitated to be dissipated through vibration of the plate strips.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a single-leg slit sound-absorbing structure. Background technique [0002] Sound-absorbing panels are an ideal sound-absorbing decorative material, widely used in concert halls, theaters, recording studios, studios, listening rooms, meeting rooms, gymnasiums, exhibition halls, dance halls, KTV rooms, home video halls, factories, Silent rooms, courtrooms, lecture halls, interrogation rooms, etc., workshops with excessive noise, and sound-absorbing wall panels and ceiling panels of large public buildings. [0003] At present, according to the structure, the sound-absorbing panels usually include sound-absorbing wedge sound-absorbing panels, grooved wood sound-absorbing panels and perforated sound-absorbing panels. Sound-absorbing wedges are conical or wedge-shaped sound-absorbing bodies made of porous or fibrous materials. Slot wood sound-absorbing panel is a structure with groo...
