Description

Technical Field

[0001] The utility model relates to the technical field of building sound absorption, in particular to a fully inclusive spatial sound absorbing body. Background Art

[0002] The sound absorbers used in buildings are generally divided into wall-fixed type and building top ceiling type. Among them, the wall-fixed type mostly uses wooden sound-absorbing panels, and the top ceiling type mostly uses space sound absorbers, which are filled with fiber sound-absorbing cotton. They are light in weight and easy to hoist. They are also wrapped with fiber cloth and aluminum alloy frames to increase the beauty of the building.

[0003] Patent application number CN215670212U discloses a fully enclosed spatial sound absorbing body, comprising a microporous sound absorbing panel and an I-beam. The microporous sound absorbing panel is symmetrically arranged in two groups. A notch is formed at the bottom between the two groups of microporous sound absorbing panels. The lower crossbeam of the I-beam is located in the notch. The top of the lower crossbeam of the I-beam is bonded and fixed to the microporous sound absorbing panel by silicone structural adhesive. The bottom of the lower crossbeam of the I-beam is covered with a second microporous sound absorbing panel. The second microporous sound absorbing panel comprises a bottom plate. Both ends of the bottom plate are bent upward to have L-shaped edges, and the L-shaped edges are fitted and fixed on the corresponding microporous sound absorbing panel.

[0004] The above-mentioned spatial sound absorbing body fixes the I-beam and two sets of microporous sound absorbing panels by silicone structural adhesive. This glue-adhering fixing method is not conducive to disassembly of the spatial sound absorbing body, thereby making it inconvenient to replace and recycle the I-beam and the microporous sound absorbing panels.

[0030] The utility model provides a fully inclusive spatial sound absorbing body. Figure 1-4, including an I-beam 100, a locking component 200 and a sound absorbing panel 300;

[0031] Please continue reading Figure 1-4 , as an I-beam 100 connecting the base frame, a through hole is opened in the center of the I-beam 100 and a bearing seat 110 is embedded;

[0032] Please continue reading Figure 1-4 , the locking component 200 is connected to the I-beam 100 to lock the I-beam 100 and the sound absorbing board 300;

[0033] The locking component 200 includes a double-headed screw 210 connected to the bearing seat 110 (the double-headed screw is clamped in the central position of the bearing seat and rotates from the I-beam through the bearing seat), and both ends of the double-headed screw 210 are connected to a pressure plate 220, and the two groups of pressure plates 220 rotate synchronously with the double-headed screw 210. The central position of the pressure plate 220 is provided with a threaded hole 221 that is threadedly matched with the double-headed screw 210, and the top of the pressure plate 220 is limited and slidably matched with the top beam of the I-beam 100;

[0034] action:

[0035] The double-headed screw 210 is rotated by the rotary seat 212, and the double-headed screw 210 rotates, driving the two groups of pressing plates 220 to perform a thread feeding action, so that the two groups of pressing plates 220 move toward each other or relative to each other synchronously, and then the two groups of sound-absorbing panels 300 are clamped and fixed synchronously by the pressing plates 220 (the two groups of pressing plates move toward each other to clamp, and move relative to each other to loosen). The detachable locking connection mode facilitates the subsequent disassembly, assembly and replacement of the sound-absorbing panels 300, and is also convenient for the recycling of the I-beam 100 and the sound-absorbing panels 300;

[0036] Please continue reading Figure 1 , Figure 3 and Figure 4 , the sound absorbing panels 300 are connected to the I-beam 100, and there are two groups of sound absorbing panels 300, which are symmetrically arranged, and a notch (not marked in the figure) is formed at the bottom between the two groups of sound absorbing panels 300, and the lower crossbeam of the I-beam 100 is located in the notch;

[0037] Furthermore, the rear end of the double-headed screw 210 is connected to the rotating seat 212, the front end of the double-headed screw 210 is connected to the limiting seat 230, and the outer side of the rotating seat 212 is provided with a plurality of groups of anti-slip grooves (not marked in the figure) in an annular and equidistant manner, the front end of the double-headed screw 210 is provided with a thread groove 211, and the outer side of the limiting seat 230 is integrally formed with a stud 231 that is threadedly matched with the thread groove 211;

[0038] The stud 231 cooperates with the thread groove 211 to facilitate the connection with the limit seat 230. When the limit seat 230 is limited, the sound absorbing board 300 is conveniently connected with the I-beam 100 (the limit seat is inconvenient to disassemble and assemble the double-headed screw due to the position limitation of the limit seat, so the limit seat is set to a detachable fixed connection mode);

[0039] Furthermore, a holder 120 is integrally formed and connected to the bottom beam of the I-beam 100, and a slot 310 adapted to the slot 120 is provided at the bottom of the sound absorbing panel 300 corresponding to the position of the holder 120. The slot 310 is arranged corresponding to the holder 120, which can ensure auxiliary guidance of the sound absorbing panel 300 when the sound absorbing panel 300 is clamped and fixed.

[0040] Working principle: When the utility model is in use, after the sound absorbing panel 300 is placed on the I-beam 100, the double-headed screw 210 is driven to rotate through the rotary seat 212, so that the two groups of pressure plates 220 perform thread feeding action, and the two groups of pressure plates 220 move toward each other synchronously, and then the two groups of sound absorbing panels 300 are clamped and fixed synchronously by the pressure plates 220. The detachable locking connection method facilitates the subsequent disassembly, assembly and replacement of the sound absorbing panel 300, and is also convenient for the recycling of the I-beam 100 and the sound absorbing panel 300.

[0041] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention.

Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
