Abstract
Description
Technical Field
[0001] This utility model relates to a multi-layer composite sound-absorbing panel installation structure, which is a structure for installing a composite sound-absorbing panel with multiple core materials. It belongs to the field of sound absorption and noise reduction technology, and particularly relates to an installation structure that installs the composite sound-absorbing panel using a splicing installation frame, which can prevent damage to the first and second sound-absorbing core panels during the installation of the sound-absorbing panel. Background Technology
[0002] Sound-absorbing panels are an ideal sound-absorbing decorative material with functions such as sound absorption, flame retardancy, and heat insulation. Microporous sound-absorbing panels are widely used in theaters, concert halls, conference rooms, and other places due to their high strength, light weight, and ease of small-batch customization. Microporous sound-absorbing panels are usually composed of a veneer, a core material, and a sound-absorbing felt. Small holes are opened on the surface of the core material. Sound enters the holes of the sound-absorbing panel and vibrates with friction against the internal cavity, converting sound energy into heat energy for sound absorption. Existing microporous sound-absorbing panels usually have sound-absorbing micropores opened on the surface of a single-layer core board. The size, density, shape, and arrangement of the holes are fixed, which can only absorb sound in a single frequency band, resulting in a small sound absorption frequency range and unsatisfactory sound absorption effect.
[0003] To improve the above situation, the applicant filed a separate utility model patent application entitled "A Multi-Layer Composite Sound Absorbing Panel". This application expands the sound absorption frequency range and improves the sound absorption effect by setting up a double-layer sound-absorbing core panel with different shapes, sizes, densities and arrangements of sound-absorbing micropores on the double-layer sound-absorbing core panel. However, most of the sound-absorbing panel installation methods on the market are designed for single-layer sound-absorbing panels. They usually use a straight row of nails for installation. That is, after the keel is installed, the straight row of nails passes through the holes and is driven into the keel to fix the sound-absorbing panel. However, the first and second sound-absorbing micropores of the multi-layer composite sound-absorbing panel are arranged alternately. Using a straight row of nails for installation will damage the overall structure of the second sound-absorbing core panel and may even cause cracks in the second sound-absorbing core panel, affecting the overall sound absorption performance. Utility Model Content
[0004] To improve upon the above situation, this utility model provides a multi-layer composite sound-absorbing panel installation structure. This structure uses interlocking blocks and grooves to assemble multiple sound-absorbing panel mounting frames into a mounting frame for installing the composite sound-absorbing panel. The mounting frame is then fixed to the wall using straight nails. This installation structure prevents damage to the first and second sound-absorbing core panels during the installation of the composite sound-absorbing panel.
[0005] The installation structure of this multi-layer composite sound-absorbing panel is implemented as follows: This multi-layer composite sound-absorbing panel installation structure consists of reinforcing plates, straight nails, splicing blocks, a sound-absorbing panel mounting frame, splicing grooves, and mounting holes. The sound-absorbing panel mounting bracket has a splicing groove at one end and a splicing block at the other end. Preferably, the sound-absorbing panel mounting bracket has a linear structure. Preferably, the sound-absorbing panel mounting bracket has multiple sound-absorbing micro-holes on its side, and these micro-holes are arranged at equal intervals along the length of the mounting bracket. The reinforcing plate is placed on the sound-absorbing panel mounting bracket. The reinforcing plate has multiple mounting holes, and each mounting hole corresponds to one of the sound-absorbing micropores. Preferably, the reinforcing plate is provided with a decorative veneer. The straight row of nails is placed inside the mounting holes and corresponds to the sound-absorbing micropores. Preferably, the straight row of nails has connecting threads, and the mounting hole has threads, so that the straight row of nails and the mounting hole are threadedly connected. Preferably, the two sound-absorbing panel mounting brackets are connected at the middle to form a cross-shaped mounting structure. Preferably, multiple cross-shaped mounting structures are joined together by splicing blocks and splicing grooves to form a mounting frame for installing the composite sound-absorbing panel. The composite sound-absorbing panel is placed inside the mounting frame. Preferably, the composite sound-absorbing panel and the mounting frame are fixedly connected; Furthermore, the splicing block has a first fastening through groove, and the side wall of the splicing groove has a second fastening through groove, with the first fastening through groove and the second fastening through groove corresponding to each other; Furthermore, the sound-absorbing panel mounting bracket has two T-shaped slots, which are symmetrically arranged about the sound-absorbing panel mounting bracket. Beneficial effects
[0006] By using a modular mounting frame to install the composite sound-absorbing panel, the first and second sound-absorbing core panels can be installed without damaging them.
[0007] It has a simple structure and is easy to use.
[0008] It is inexpensive and easy to promote. Attached Figure Description

Preferably, the connecting latch is placed in the connecting groove to lock the first sound-absorbing core board inside the sound-absorbing frame. At the same time, the first sound-absorbing core board presses the second sound-absorbing core board and the sound-absorbing felt into the sound-absorbing frame. Preferably, the surface of the first sound-absorbing core board is provided with a decorative veneer. Preferably, there are multiple first sound-absorbing micropores, and the multiple first sound-absorbing micropores and multiple second sound-absorbing micropores are arranged alternately.

Preferably, the composite sound-absorbing panel and the mounting frame are fixedly connected by welding; In use, firstly, multiple cross-shaped installation structures are spliced together with splicing blocks 3 and splicing grooves 5 to form an installation frame. The composite sound-absorbing panel is installed in the installation frame. The sound-absorbing frame and the sound-absorbing panel mounting bracket 4 are fixedly connected on the side. The installation frame and the composite sound-absorbing panel are nailed to the keel by passing straight nails 2 through the installation holes 6 and the corresponding sound-absorbing micro holes. The number of cross-shaped installation structures to be spliced is determined according to the wall area until the composite sound-absorbing panel covers the entire wall. Example 2
[0012] The difference between this embodiment and embodiment 1 is that: the splicing block 3 has a first fastening through groove 8, and the side wall of the splicing groove 5 has a second fastening through groove 9, the first fastening through groove 8 and the second fastening through groove 9 correspond to each other; in use, after the cross-shaped installation structure is spliced together by the splicing block 3 and the splicing groove 5, the splicing block 3 is fixed by fastening bolts passing through the first fastening through groove 8 and the second fastening through groove 9, which can increase the connection stability of the splicing block 3, so that the entire installation frame can provide more stable support for the composite sound-absorbing panel; Example 3
[0013] The difference between this embodiment and embodiment 1 is that: the sound-absorbing panel mounting frame 4 has T-slots 10, and there are two T-slots 10. The two T-slots 10 are symmetrically arranged about the sound-absorbing panel mounting frame 4. Preferably, the outer side of the sound-absorbing frame is provided with T-blocks corresponding to the T-slots 10. In use, the T-blocks are first inserted into the T-slots 10, and then multiple cross-shaped mounting structures are assembled together by splicing blocks 3 and splicing slots 5. The composite sound-absorbing panel and the mounting frame are interlocked and connected. Compared with the welding method, it is more convenient to use. The sound-absorbing panel mounting frame has a double-layer structure. The outer layer is made of metal and the inner layer is filled with sound-absorbing material. The outer layer is made of metal, which can provide stable support for the composite sound-absorbing panel. The inner layer is filled with sound-absorbing material, which can absorb sound and meet the dual requirements of stability and noise reduction. The sound-absorbing panel mounting bracket has multiple sound-absorbing micro-holes on its side. The design of the multiple sound-absorbing micro-holes being equidistantly arranged along the length of the sound-absorbing panel mounting bracket allows the sound-absorbing micro-holes to absorb sound waves when they are transmitted to the position of the sound-absorbing panel mounting bracket. This, together with the sound-absorbing material, improves the sound absorption performance of the sound-absorbing panel mounting bracket and provides support for the driving of the straight nails 2. The design of the reinforcing plate 1 connecting the straight nails 2 with the mounting holes 6 can improve the support strength of the sound-absorbing panel mounting frame, make the connection between the straight nails 2 and the sound-absorbing panel mounting frame more stable, and make the installation of the composite sound-absorbing panel by the mounting frame more stable. The goal is to enable multiple sound-absorbing panel mounting frames to be assembled together to form an installation frame by using splicing blocks 3 and splicing grooves 5, and to install composite sound-absorbing panels. The installation frame is fixed to the wall by straight nails 2, so as not to damage the first and second sound-absorbing core panels while installing composite sound-absorbing panels.
