Description

Technical Field

[0001] This utility model relates to an installation structure for a sound-absorbing module, and more particularly to an installation structure for a side wall sound-absorbing module used in computer rooms, soundproof enclosures, etc. Background Technology

[0002] Indoor sound-absorbing walls are used in places requiring internal sound absorption, such as machine rooms and soundproof enclosures. Existing indoor sound-absorbing walls with internal cavities (which improve sound absorption) typically consist of a foundation, a frame, sound-absorbing panels, and installation accessories. The sound-absorbing panels are composed of perforated panels, side steel plates, sound-absorbing material, and back wire mesh. The side steel plates are fixed to the frame, and the back wire mesh is fixed to the side steel plates. Sound-absorbing material is filled inside the sound-absorbing panels. The perforated panels serve as the protective panels for the sound-absorbing panels.

[0003] This type of setup requires adaptive adjustments to the size of the sound-absorbing panels based on the area of ​​the sound-absorbing wall and the sound-absorbing requirements; there is no situation where a specific size of sound-absorbing panel is always used. Panels with high sound-absorbing requirements require more metal panels, resulting in higher material costs, and the installation process, which varies depending on the size, is time-consuming and labor-intensive.

[0004] Another installation structure for indoor sound-absorbing walls is to replace the back steel wire plate in the aforementioned installation structure with aluminum foil, while the perforated metal clips remain as the facing decorative panels for the sound-absorbing panels. Typically, the sound-absorbing material of this type of sound-absorbing panel is fixed to the perforated metal clips using a perforated metal clip with a large side area. A small inward-bent flange is punched into the side panel of the perforated metal clip, which limits and presses against the aluminum foil covering the back of the sound-absorbing material, thus pressing the aluminum foil against the sound-absorbing material. When the thickness of the sound-absorbing material is greater than 25mm, a perforated metal clip with a larger side panel height (typically around 50mm) needs to be selected to allow for the creation of the small flange that can limit and press against the aluminum foil. Therefore, this type of installation structure has the drawback of requiring additional costs to purchase or produce perforated metal clips. In addition, as the years of use increase, the sound-absorbing material will age or soften, and relying on the small flange to press against the aluminum foil for local restraint is insufficient to overcome the collapse of the sound-absorbing material caused by aging or softening. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide an installation structure for a sound-absorbing module for the side wall of a soundproofing site that is simple in structure, uses little material, and is easy to install.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] The present invention discloses an installation structure for a sound-absorbing module on the side wall of a noise-reducing area, comprising a frame fixed to the side wall and several sound-absorbing panels installed on the frame. The frame is characterized in that: the frame is composed of multiple parallel Z-shaped keels spaced apart from bottom to top; the inner panel of the Z-shaped keel is fixed to the side wall with bolts; a triangular keel is fixed to the outer panel of the Z-shaped keel; and the sound-absorbing panel is installed between two adjacent triangular keels.

[0008] The sound-absorbing panel consists of a wire mesh frame, sound-absorbing material, and a perforated metal buckle plate with four side plates, from the inside out. The sound-absorbing material and the wire mesh frame are placed within the space enclosed by the four side plates. On the four side plates of the perforated metal buckle plate, there are positioning plates that are bent inward and used to fix the wire mesh frame, sound-absorbing material, and perforated metal buckle plate together. Each positioning plate is inserted into a corresponding mesh hole on the wire mesh frame.

[0009] The upper and lower side plates of the perforated metal buckle are respectively inserted into the keel joints of the corresponding triangular keel.

[0010] The Z-shaped keel consists of a base keel and an upper keel. The base keel is placed at the bottom of the side wall, and the upper keel is placed above the base keel. A support base plate that bends inward is provided at the lower end of the outer panel of the base keel. The support base plate can be fixed to the ground of the soundproofing area with bolts.

[0011] The outer panel of the base keel is at a different height than the outer panel of the upper keel.

[0012] The thickness of the base keel is greater than the thickness of the upper keel.

[0013] The thickness of the upper keel is between 0.5mm and 3.0mm.

[0014] This utility model employs a novel installation structure to construct an indoor sound-absorbing wall with an internal cavity. The basic structure of this indoor sound-absorbing wall uses a combination of Z-shaped keel and triangular keel, resulting in high installation efficiency. The sound-absorbing panels, composed of steel wire mesh, sound-absorbing materials, and perforated metal buckles, not only save materials but also extend the service life and ensure good stability of the indoor sound-absorbing wall. Furthermore, the width of the middle horizontal panel of the Z-shaped keel or the height of the outer panel can be changed as needed to adapt to the requirements of different sound-absorbing walls with internal cavities.

Detailed Implementation

[0030] like Figures 1-10 As shown, the installation structure of the sound-absorbing module of the side wall of the soundproof place of this utility model is used to install several sound-absorbing panels 7 on the indoor sound-absorbing wall 2 with an inner cavity 11 in a simple and quick way. The installation structure includes several Z-shaped keels, triangular keels 6 and sound-absorbing panels 7 installed on the sound-absorbing wall (especially on the wall of the indoor side wall 1).

[0031] 1. Z-shaped keel

[0032] The Z-shaped keel consists of an inner panel 51, a middle horizontal panel 52, and an outer panel 53 (the direction closer to the wall is the inner side, and the direction farther from the wall is the outer side, the same below). This utility model preferably has two types of Z-shaped keels, namely the base keel 3 and the upper keel 4.

[0033] 1) The base keel 3 is a single piece placed at the bottom of the side wall, serving to bear the load of the entire sound-absorbing wall. Its inner panel 51 is fixed to the interior side wall 1 using expansion bolts or core expansion nails and other fasteners. A support base plate bent inwards is provided at the lower edge of the outer panel 53 of the base keel 3. This support base plate can be bolted to the interior floor (see...). Figure 5 , Figure 6 , Figures 7-9 (As shown).

[0034] The height of the outer panel 53 of the base keel 3 can be greater than or equal to the height of the outer panel 53 of the upper keel 4 as needed. The thickness of the base keel 3 is preferably greater than the thickness of the upper keel 4, that is, the strength of the base keel 3 is preferably greater than the strength of the upper keel 4.

[0035] 2) The upper keel 4 consists of several pieces arranged vertically, positioned above the base keel 3 (see...). Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 10 As shown), it is used to bear the load of a single layer of sound-absorbing panel 7. Two adjacent keels 4 are arranged in parallel with a gap. The inner panel 51 is fixed to the wall of the interior side wall 1 by fasteners such as expansion bolts or core expansion nails. The thickness of the upper keel 4 is 0.5mm-3.0mm, preferably 1.5mm.

[0036] The middle horizontal panel 52 and / or the outer side panel 53 of the Z-shaped keel can be bent to the required width (width for the middle horizontal panel 52 and height for the outer side panel 53) to meet various requirements for the width distance of the inner cavity 11.

[0037] 2. Triangular keel 6

[0038] like Figures 7-10 As shown, a triangular keel 6 is fixed to the outer panel 53 of each Z-shaped keel, with the keel joint 61 of the triangular keel 6 facing outward, and a sound-absorbing panel 7 is installed between two adjacent triangular keels 6.

[0039] The triangular keel 6 on the base keel 3 can be fixed to the upper, middle or lower area of ​​the outer panel 53 of the base keel 3 according to the installation height of the sound-absorbing panel 7.

[0040] 3. Sound-absorbing panel 7

[0041] like Figures 11-13 As shown, the sound-absorbing panel 7 consists of a wire mesh frame 76, a sound-absorbing material 75, and a perforated metal buckle plate 71 (also known as a perforated aluminum buckle decorative panel) with four side plates, from the inside out. The sound-absorbing material 75 and the wire mesh frame 76 are placed within the space enclosed by the four side plates.

[0042] At least one positioning plate 74 is provided on each of the four side plates of the perforated metal buckle plate 71, which bends inward (inward means the direction pointing to the center of the perforated metal buckle plate 71). The positioning plate 74 can be inserted into the mesh of the wire mesh frame 76 to fix the wire mesh frame 76, the sound-absorbing material 75 and the perforated metal buckle plate 71 together. This arrangement can utilize the elastic properties of the sound-absorbing material to fix the sound-absorbing material firmly on the perforated metal buckle plate 71 by applying pressure through the positioning plate 74.

[0043] The upper side plate 72 and lower side plate 73 of the perforated metal buckle plate 71 on each sound-absorbing panel 7 are respectively inserted into the keel joint 61 of the corresponding triangular keel 6, thereby allowing the sound-absorbing panel 7 to be quickly installed on the interior side wall 1.
