Description

Technical Field

[0001] This utility model belongs to the field of home decoration materials technology, and in particular relates to an integrated sound insulation board. Background Technology

[0002] Integrated sound insulation panels are a modern building material that combines decoration and sound insulation functions. They typically consist of a multi-layered structure, including a sound-absorbing layer, a sound-insulating layer, and a protective layer. They not only effectively reduce noise pollution but also provide a good decorative effect. Their main applications include homes, offices, schools, hospitals, and other places requiring a quiet environment. There are various installation methods for integrated sound insulation panels, the most common being flat mounting and hanging. Flat mounting involves fixing the panels to the wall using structural components. In cases of extremely uneven walls or when a specific design is required, an additional frame can be installed on the wall, and the sound insulation panels can be mounted on the frame. Hanging mounting involves fixing the sound insulation panels to the ceiling using a hanging device.

[0003] Chinese patent document CN213682813U discloses a wall panel with good sound insulation effect, including a wall panel body. The wall panel body is composed of a base layer, a sound insulation layer, and a corrosion-resistant layer. The base layer is located at the bottom of the sound insulation layer, and the sound insulation layer is located at the bottom of the corrosion-resistant layer. The sound insulation layer is composed of a sound insulation cotton layer, a honeycomb panel layer, and a polyester fiber sound-absorbing panel layer. The sound insulation cotton layer is located on top of the honeycomb panel layer, and the honeycomb panel layer is located on top of the polyester fiber sound-absorbing panel layer. Through the cooperation of the sound insulation layer, the sound insulation cotton layer, the honeycomb panel layer, and the polyester fiber sound-absorbing panel layer, the wall panel can achieve a good sound insulation effect during use.

[0004] In the aforementioned patented design, both the sound insulation layer and the corrosion-resistant layer are flexible materials lacking structural strength. When installing the wall panel, structural strips are needed to fix the base layer. The thickness of the sound insulation layer directly affects the sound insulation effect, thus creating a gap between the base layer and the wall surface. This results in a relatively long distance between the stiffening plates on the structural strip used to fix the base layer and the mounting plate of the structural strip. As the load-bearing point of the base layer, the greater the distance between the stiffening plates and the mounting plate, the lower the support strength the structural strip can provide to the sound insulation panel, thereby affecting the stability of the sound insulation panel installation. Utility Model Content

[0005] To overcome the technical problems in existing technologies where the large thickness of the sound insulation panel results in a gap between the base layer and the wall, and the structural strip's support position on the base layer is a long distance from the mounting plate of the structural strip, leading to low support strength provided by the structural strip, one objective of this utility model is to provide an integrated sound insulation panel. By setting an easily removable part on the sound insulation layer, installation space is reserved for the mounting plate of the structural strip, allowing the sound insulation panel to completely fit the wall and improve the sound insulation effect. At the same time, reinforcing ribs are inclinedly set on the structural strip to improve the support strength of the structural strip, thereby improving the installation strength of the sound insulation panel.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an integrated sound insulation panel, comprising a panel body and structural strips; the panel body comprises sound insulation felt, polyester fiber felt board, carbon fiber board, and decorative layer stacked sequentially; the carbon fiber board has female grooves on its two symmetrical side walls; the structural strips include a mounting base plate for wall mounting, positioning ribs on the mounting base plate, and at least two reinforcing ribs between the mounting base plate and the positioning ribs; the positioning ribs are inserted into the female grooves; wherein, the end of the sound insulation felt near the female groove is separated from the polyester fiber felt board; the sound insulation felt has at least two easy-tear grooves respectively near the two female grooves; the end of the sound insulation felt near the female groove is easily separable.

[0007] The sound insulation felt has a good sound insulation effect on high-frequency sounds; the polyester fiber felt board has a good sound insulation effect on mid- and low-frequency sounds; the carbon fiber board has a certain sound insulation effect; when the three materials are combined, they have a good sound insulation effect on high, medium and low-frequency sounds, with an average sound insulation value of 48.36dB.

[0008] The sound insulation felt has a certain degree of toughness. When installed directly, a gap will remain between the sound insulation felt and the wall due to the presence of the mounting base. The sound insulation felt is torn off along the easy-tear groove on both sides. The torn portion provides installation space for the mounting base, ensuring the sound insulation felt adheres completely to the wall, reducing sound transmission through gaps. Simultaneously, the polyester fiber felt board is tightly pressed and compressed against the reinforcing ribs, buffering the vibration of the structural strips and preventing sound bridging and resonance (i.e., preventing sound transmission through the structural strips), further improving the sound insulation effect.

[0009] Furthermore, the end of the polyester fiber felt board near the mother groove is separated from the carbon fiber board; an auxiliary rib is provided on the mounting base plate; the auxiliary rib abuts against the end of the carbon fiber board away from the decorative layer.

[0010] The auxiliary stiffeners further improve the installation strength of the plate body and prevent it from shaking.

[0011] Specifically, one end of the reinforcing rib is located in the middle of the auxiliary rib plate, and the other end is located on the mounting base plate; there are two reinforcing ribs arranged symmetrically; and there is an angle between the reinforcing rib and the mounting base plate.

[0012] Specifically, a joint filler plate is provided between the middle of the auxiliary stiffener plate and the middle of the positioning stiffener plate; one end of the joint filler plate near the positioning stiffener plate extends outward through the positioning stiffener plate; the extended end of the joint filler plate is flush with the finishing layer.

[0013] Furthermore, a fixing strip for installing screws is provided on one side wall of the mounting base plate; four easy-tear grooves are provided on the sound insulation felt; each easy-tear groove includes a plurality of through grooves that are evenly spaced along a linear axis and penetrate the sound insulation felt; the distance between two adjacent easy-tear grooves is equal to the width of the fixing strip; the distance between the female groove and the adjacent easy-tear groove is equal to half the width of the mounting base plate.

[0014] Preferably, thickened strips are provided on both sides of the positioning rib plate; guide angles are provided on the thickened strips.

[0015] Specifically, the thickness of the mounting base plate is equal to the thickness of the sound insulation felt; the two side walls of the mounting base plate are respectively provided with protruding strips extending away from the positioning rib plate.

[0016] Preferably, the end of the finishing layer near the mother groove abuts against the inner bottom of the mother groove. The outer edge of the finishing layer is pressed inside the mother groove to prevent the finishing layer from lifting or falling off.

[0017] Specifically, the carbon fiber plate has a thickness of 8mm; the polyester fiber felt has a thickness of 9mm; and the sound insulation felt has a thickness of 2mm.

[0018] Specifically, the groove is located at the center of the side wall of the carbon fiber plate; the side wall where the groove is located is stepped; the width of the groove is 2.8 mm; the depth of the groove on the side wall near the finishing layer is 6 mm; and the depth of the groove on the side wall away from the finishing layer is 5.2 mm.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model combines three materials that have good sound insulation effects for low, medium and high frequencies to achieve the best sound insulation effect. During installation, there is no need to install a keel, make a cavity, or use plywood for leveling. It can be directly installed on the wall. While ensuring the sound insulation effect, it reduces space occupation, shortens the construction process, and reduces the overall cost.

[0021] 2. This utility model features an easy-tear edge design for the sound insulation felt attached to the wall, which provides installation space for the mounting base of the structural strip. The sound insulation felt can fit tightly against the wall, preventing sound from being transmitted through gaps and improving the sound insulation effect. At the same time, the polyester fiber felt board is pressed against the structural strip, buffering the vibration and sound transmission of the structural strip and preventing sound bridging and resonance, further improving the sound insulation effect.

[0022] 3. The structural strip of this utility model has reinforcing ribs between the mounting base plate and the positioning rib plate, which reduces the cantilever length of the positioning rib plate and improves the stress structure, thereby enabling the structural strip to provide better support for the main body of the plate and improve the installation strength of the main body of the plate.
