Description

Technical Field

[0001] The utility model relates to a sound insulation wall system, belonging to the technical field of building decoration. Background Art

[0002] In order to improve the sound insulation performance of the sound insulation wall system, a variety of products have been launched on the market. Their structure is optimized based on the solution of light steel keel gypsum board partition wall. The main components are top and bottom keels, sound insulation keels, through keels, cross-bracing keels, rock wool and double-layer gypsum boards.

[0003] At present, the following problems exist in the implementation of the sound insulation wall system:

[0004] First, it can only be installed in sequence, which makes construction inconvenient: Due to the shape restrictions of the ceiling and ceiling keels and the sound insulation keels, when installing the sound insulation panels (usually calcium silicate panels), they can only be installed in sequence, with poor installation flexibility, resulting in low construction efficiency; and when there are design changes, damaged materials and replacements, and later repairs and replacements, the entire sound insulation wall needs to be demolished, and the problem panels cannot be replaced individually.

[0005] Second, the sound insulation effect is poor: In traditional sound insulation wall systems, for ease of installation, there is a gap between the sound insulation board in the middle and the floor keel. The sound insulation board does not directly support the ceiling and needs to be filled with materials after installation. The calcium silicate board is installed in the middle, and its height is less than the height of the partition wall minus the size of the floor keel fracture edge. Therefore, a cavity appears at the top, which reduces its integrity and weakens the sound insulation performance.

[0006] Third, it is necessary to increase the decorative surface structure space on its basis: the traditional solution mostly uses gypsum board cover, the gypsum board is fixed to the keel with screws, and then putty and latex paint are applied on the gypsum board. If other decorative effects are required, the decorative surface structure is installed on the basis of the gypsum board. Utility Model Content

DETAILED DESCRIPTION

[0034] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0035] Example 1:

[0036] This embodiment provides a sound insulation wall system that optimizes a traditional one-piece keel (which is a single unit along the wall thickness, i.e., its width is the same as the wall thickness) into a split type (divided into two independent parts along the wall thickness). This system uses material spacing to interrupt the propagation path, effectively blocking sound transmission and achieving excellent sound insulation. Furthermore, the use of the split keel allows for flexible layout and eliminates the need for sequential installation, resulting in higher construction efficiency and more scientific construction organization.

[0037] like Figure 1 and Figure 2 As shown, the sound insulation wall system includes: a multifunctional keel 4, a sound insulation board 5, a sound insulation rock wool 3, a limiting keel 2, a leveling keel 7 and a keel connector 2. As an example, the sound insulation board 5 is made of 12mm calcium silicate board.

[0038] The multifunctional keel 4 is not only used to install the sound insulation board 5, but also used to hang the decorative board. Figure 3 As shown, the multifunctional keel 4 is a frame structure with a rectangular cross-section, comprising a support surface A41 and a mounting surface 42 positioned opposite each other in the wall thickness direction, and side surfaces A43 and B44 positioned opposite each other in the wall length direction. The support surface A41 is a vertical plane, and the mounting surface 42 has a splice 422 in the middle, with mounting holes 421 on either side of the splice 422. As an example, the splice A422 is formed by two V-shaped structures with opposing tips. The mounting holes 421 are spaced apart along the height direction of the mounting surface 42. Splice slits B45 are formed at opposing positions (preferably in the middle of the width direction) on the side surfaces A43 and B44 for connecting the keel connector 10. When in use, the mounting surface 42 of the multifunctional keel 4 faces outward, and the mounting holes 421 and splice A422 allow for the installation of a variety of decorative panels, eliminating the need for a separate decorative panel structure.

[0039] The width of the multifunctional keel 4 is less than half of the wall thickness, and the solution for the seams on both sides of the wall (such as Figure 1 As shown), the multifunctional keels 4 are used in pairs along the thickness direction of the wall, the supporting surfaces A41 are relatively spaced apart (the middle is used to set the sound insulation board), and the hanging surface 42 faces outward.

[0040] The multifunctional keel of this structure can be flexibly combined and can be used on both sides or on one side. Figure 1 Symmetrical setup as shown or as Figure 7 When a multifunctional keel 4 is fixed to the structural wall, the multifunctional keel 4 serves as the skeleton base of the decorative panel.

[0041] like Figure 6 As shown, the keel connector 10 has a horizontal limiting portion 101 and a plug-in portion 102 for plugging into the plug-in seam B45; wherein the limiting portion 101 is used to achieve the limitation of the sound insulation board 5 in the thickness direction.

[0042] The limiting keel 2 is installed on the top plate of the structure to achieve temporary fixation of the multifunctional keel 4 during the construction process and to ensure that the multifunctional keel 4 does not move forward or backward after the construction is completed (i.e., to achieve the limitation of the multifunctional keel 4). The limiting keel 2 is set horizontally along the long end of the wall, such as Figure 5 As shown, the limiting keel 2 has two independent limiting cavities 21 along the wall thickness direction, which are used to limit the multifunctional keels 4 on both sides of the thickness direction. That is, the top of the multifunctional keel 4 is installed in the limiting cavity 21 on the corresponding side of the ceiling limiting keel 2, and the limiting cavity 21 can achieve temporary fixation of the multifunctional keel 4. Each limiting cavity 21 has an extension cavity 22 above it. The top surface of the extension cavity 22, i.e., the top surface of the limiting keel 2, is connected to the structural top plate via fasteners. The extension cavity 22 is filled with sound-absorbing cotton 6.

[0043] The bottom of the multifunctional keel 4 is placed on the leveling unit, and the leveling unit adjusts the height of the multifunctional keel 4 so that the bottoms of all multifunctional keels 4 are located in the same horizontal plane, thereby ensuring the level of the sound insulation wall system. Specifically: the leveling unit includes a leveling keel 7 and a leveler 8; Figure 4As shown, the leveling keel 7 is horizontally arranged along the length of the wall. A concave cavity 701 is located in the middle of the leveling keel 7 (the middle of the wall thickness) for mounting a leveler 8, which can be moved up and down for height adjustment. Support surfaces B702 are located on either side of the concave cavity in the middle of the leveling keel 7 to support the multifunctional keel 4 on the corresponding side. The upper surface of the leveler 8 also serves as the multifunctional keel support surface. Limiting grooves are symmetrically located on both sides of the upper surface of the leveler 8 along the wall thickness to limit the position of the multifunctional keel on the symmetrical side. Before installing the multifunctional keel, use the support surface B702 of the leveling keel 7 as a horizontal reference surface and adjust the height of the upper surface of the leveler 8 to be at the same level as the support surface B702. When installing the multifunctional keel 4, the lower end of the multifunctional keel 4 is supported on one side by the support surface B702 and on the other side by the upper surface of the leveler 8, with the side surfaces of the multifunctional keel 4 being limited in the limiting grooves on the upper surface of the leveler 8.

[0044] In addition, a U-shaped keel 9 is installed on the structural bottom plate for positioning the sound insulation wall system; and the leveling unit is installed on the U-shaped keel 9 .

[0045] like Figure 1 and Figure 2 As shown, in this sound insulation wall system, a limit keel 2 is horizontally installed on the top plate of the structure; the multifunctional keels 4 are used in pairs, two in a group; multiple groups of multifunctional keels 4 are spaced apart along the length of the wall, and the supporting surfaces A41 of the two multifunctional keels 4 in each group are spaced apart relative to each other, and the top of the multifunctional keel 4 is limited in the limit cavity 21 on the corresponding side of the limit keel 2. After the multifunctional keel 4 is installed (after installation, the top of the multifunctional keel 4 is connected to the limit keel 2 by fasteners), the keel connector 10 (as shown in FIG. 1 ) is uniformly installed on one side. Figure 1 As shown, the keel connector 10 is uniformly installed along one side of the multifunctional keel 4 in the thickness direction. The connector portion 102 of the keel connector 10 is inserted into the insertion seam B45 on both sides of the multifunctional keel 4. The sound insulation panel 5 is installed between the multifunctional keels 4 in the thickness direction. The keel connector 10 ensures positioning of the sound insulation panel 5 during installation and securement after installation. In this solution, the size of the sound insulation panel 5 is not restricted and can be full-length or spliced ​​together to any length. The sound insulation panel 5 can be installed after the multifunctional keel 4 and the keel connector 10 on one side are installed (the sound insulation panel 5 can be installed after both multifunctional keels 4 are installed). In this example, the sound insulation panel 5 is available in two sizes: a standard length (approximately 960 mm) and a 45 mm length. The bottom end of the sound insulation panel rests on the leveling unit and is secured to the center of the wall by the keel connectors 10 on both sides. The sound insulation panel 5 and the keel connectors 10 are securely fastened with screws. Sound insulation cotton 3 is filled between the adjacent multifunctional keels 4 on each side; finally, film-coated metal plates are arranged on the outer surfaces of both sides, and the film-coated metal plates are fixed on the multifunctional keels 4 on the corresponding sides, thereby forming a closed partition wall.

[0046] Holes are provided on the outermost coated metal plate on each side at positions corresponding to the hanging holes 421 and the plug-in seams A422 on the multifunctional keel 4, so that the system can directly install decorative panels, and two forms of panel installation can be achieved: one is hanging and the other is plug-in.

[0047] The core components of this sound insulation system are the split multifunctional keel 4 (divided into two parts along the thickness direction), the limiting keel 2, the leveling keel 7 and the keel connector 10. The original integrated sound insulation keel is innovated and optimized into a split multifunctional keel 4, which can adapt to more decoration scenes. The limiting keel 3 is also different from the conventional system. Through the structural setting, the multifunctional keel 4 can be temporarily fixed and limited. The left and right sides of the multifunctional keel 4 are designed with plug-in seams B45, which are used with the keel connector 10 to realize the disordered installation of the entire system. At the same time. The multifunctional keel 4 combines the hanging holes 421 and the plug-in seams A422, which can meet the needs of various forms of hanging panels and realize more installation requirements.

[0048] The installation steps of the sound insulation wall system are:

[0049] S1: First, install the limiting keel 2 on the top plate of the structure; install the U-shaped keel 9 and the leveling unit on the bottom plate of the structure, and adjust the height of the leveler 8 in the leveling unit so that the upper surface of the leveler 8 is flush with the support surface B702 of the leveling keel 7;

[0050] S2: Multifunctional keels 4 are then installed. These keels 4 are arranged vertically and used in pairs. The tops of the keels are inserted into the retaining cavities 21 on the corresponding sides of the retaining keels 2, temporarily securing the keels 4 and preventing them from moving forward or backward. Multiple groups of multifunctional keels 4 are spaced apart along the length of the retaining keels 2. These keels 4 serve as the load-bearing components of the sound insulation panels 5.

[0051] S3: After the multifunctional keel 4 is installed (after the installation is completed, the top of the multifunctional keel 4 is connected to the limit keel 2 by fasteners), the keel connector 10 on one side is uniformly installed (such as Figure 1 As shown, the keel connector 10 is uniformly arranged on one side in the thickness direction, and the connecting portion 102 of the keel connector 10 is inserted into the connecting seams B45 on both sides of the multifunctional keel 4.

[0052] S5: Next, install the sound insulation board 5, which in this example is a 12 mm thick calcium silicate board. The sound insulation board 5 is located in the middle of the thickness of the sound insulation wall system and is positioned and installed using the multifunctional keel 4 and keel connector 10. After the keel connector 10 on one side of the sound insulation board 5 is installed, the sound insulation board 5 is installed uniformly.

[0053] When installing the sound insulation panel 5, one side rests on the keel connector 10, with the bottom resting on the leveling unit. Once the sound insulation panel 5 is in place, the keel connector 10 on the other side is installed. The sound insulation panel 5 is secured to the center of the wall by the multifunctional keels 4 and keel connector 10 on both sides. Self-tapping screws are then used to secure the sound insulation panel 4 and keel connector 10.

[0054] S6: Install the sound insulation cotton 3, which is a fireproof and sound-absorbing material for the sound insulation wall. It is located on both sides of the sound insulation board 5 along the thickness direction of the sound insulation wall system to enhance the sound insulation and fire resistance performance of the partition wall.

[0055] S7: After filling the sound insulation cotton 3, the film-laminated metal plate is fixed on the multifunctional keel 4 to form a closed partition wall.

[0056] Example 2:

[0057] Since the multifunctional keel 4 is a split type, the multifunctional keel 4 is also suitable for scenes where the two sides of the wall are not aligned in the thickness direction, such as Figure 7 As shown, the multifunctional keels 4 on both sides in the thickness direction are not arranged symmetrically, but are arranged at different positions on both sides according to the corresponding side wall hanging requirements.

[0058] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
