Description

Technical Field

[0001] This utility model belongs to the field of partition wall technology, and in particular relates to a prefabricated soundproof partition wall. Background Technology

[0002] Partition walls are non-load-bearing walls used to separate interior spaces of a building. Their main function is to divide different functional areas (such as bedrooms, kitchens, and bathrooms). Unlike load-bearing walls, partition walls do not bear structural loads, but they play a crucial role in spatial layout and functional zoning.

[0003] There are many types of partition wall structures on the market. For example, a prefabricated high sound insulation partition wall system with publication number CN218508741U is disclosed on the China Patent Network. This partition wall structure can achieve the effect of sound insulation, but there are some defects and shortcomings that need to be improved: (1) Although some existing partition wall structures can improve the sound insulation effect, they will lead to a significant increase in the weight and volume of the wall, which not only makes construction difficult, but may also put additional pressure on the building's load-bearing structure; (2) Most existing partition wall structures adopt an integrated design, and related components are often fixed together with fasteners such as bolts, which are difficult to disassemble, making it inconvenient to transport the partition wall structure to a designated location for on-site assembly; (3) Due to the structural design of some existing sound insulation partition wall structures, it is often necessary to drill holes on the wall surface when wiring, which will not only damage the wall, but also affect the sound insulation effect of the wall. Therefore, in view of the above problems, the prefabricated sound insulation partition wall provided by this utility model is of great significance. Utility Model Content

[0004] This utility model provides a prefabricated soundproof partition wall that combines gypsum board, sound insulation felt, and sound-absorbing cotton. Compared with traditional partition wall structures, it not only reduces weight but also improves sound insulation. Multiple weight-reducing cavities effectively reduce the overall weight of the wall, preventing excessive weight from putting additional pressure on the building's load-bearing structure. A snap-fit ​​method allows the light steel keel to be fixed between two slots without the need for bolts or other fasteners. The light steel keel can be disassembled by sliding it out of the slots, facilitating the transport of the partition wall structure to a designated location for on-site assembly. The combined action of the lead-in channel and wiring channel enables wiring and cable routing without drilling into the wall surface, effectively avoiding damage to the wall structure while ensuring sound insulation. In summary, this invention solves the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a prefabricated soundproof partition wall, comprising a wall body, a pair of slots fixedly connected to the front end of the wall body, a light steel keel installed between the slots, sound-absorbing cotton filled inside the light steel keel, sound-insulating felt provided on the front end of the light steel keel, and gypsum board provided on the front end of the sound-insulating felt.

[0007] Furthermore, the interior of the prefabricated sound insulation partition wall is provided with several weight-reducing cavities, which are circular and are distributed linearly at equal intervals along the height direction of the prefabricated sound insulation partition wall.

[0008] Furthermore, the slot-type prefabricated sound insulation partition wall is C-shaped and symmetrically distributed at the top and bottom of the front face of the prefabricated sound insulation partition wall. The thickness of the light steel keel prefabricated sound insulation partition wall is equal to the width of the inner wall of the slot-type prefabricated sound insulation partition wall, and the height of the light steel keel prefabricated sound insulation partition wall is equal to the distance between the inner walls of the two slot-type prefabricated sound insulation partition walls.

[0009] Furthermore, the front face of the prefabricated soundproof partition wall is provided with several wiring grooves. The side walls of the light steel keel prefabricated soundproof partition wall, the sound insulation felt prefabricated soundproof partition wall, and the gypsum board prefabricated soundproof partition wall are all provided with several lead wire grooves. The number of lead wire grooves and wiring grooves is the same, and the center of each lead wire groove corresponds one-to-one with the center of each wiring groove prefabricated soundproof partition wall.

[0010] Furthermore, the wiring trough, a type of prefabricated sound insulation partition wall, has an arc-shaped trough structure, and the surface of the trough wall of the wiring trough, a type of prefabricated sound insulation partition wall, is provided with several anti-wear pads, which are arc-shaped and are distributed linearly at equal intervals along the length of the wiring trough, a type of prefabricated sound insulation partition wall.

[0011] Furthermore, a sealing ring is provided on the outer surface of the prefabricated sound insulation partition wall. The sealing ring is rectangular, and its inner wall length and width are equal to the length and width of the prefabricated sound insulation partition wall, respectively. Moreover, the width of the sealing ring is equal to the distance between the prefabricated sound insulation partition wall and the gypsum board prefabricated sound insulation partition wall.

[0012] The present invention has the following advantages over the prior art:

[0013] (1) When using the prefabricated sound insulation partition wall of this utility model, the combination of gypsum board, sound insulation felt and sound absorption cotton can not only reduce the weight of the partition wall structure compared with the traditional partition wall structure, but also improve the sound insulation effect. The overall weight of the wall can be effectively reduced through multiple weight reduction cavities to prevent the excessive weight of the wall from causing additional pressure on the building's load-bearing structure.

[0014] (2) When using the prefabricated sound insulation partition wall of this utility model, the light steel keel can be fixedly installed between two slots by snap-fitting, without the need for fasteners such as bolts. The light steel keel can be disassembled by sliding the light steel keel out of the slot, so that the partition wall structure can be transported to the designated location for on-site assembly.

[0015] (3) When using the prefabricated sound insulation partition wall of this utility model, the wiring and routing can be realized through the combined action of the lead wire groove and the wiring groove, without the need to drill holes on the wall surface. This not only effectively avoids damage to the wall structure, but also ensures the sound insulation effect of the wall.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Please see Figure 1-5 As shown, this utility model discloses a prefabricated soundproof partition wall, including a wall body 1. A pair of slots 2 are fixedly connected to the front end of the wall body 1. A light steel keel 3 is installed between the slots 2. The interior of the light steel keel 3 is filled with sound-absorbing cotton 4. The sound-absorbing cotton 4 can be made of sound-absorbing materials such as rock wool, glass wool, and polyester fiber. It can dissipate sound energy through fiber friction, especially for mid-to-high frequency noise. The front end of the light steel keel 3 is provided with sound-insulating felt 5. The sound-insulating felt 5 can be used to buffer vibration to block solid-borne sound (such as footsteps and impact sounds). The front end of the sound-insulating felt 5 is provided with gypsum board 6. The gypsum board 6 is a high-density material and can act as a "mass layer" to reflect and absorb sound energy through its own weight. This partition wall structure combines gypsum board 6, sound-insulating felt 5, and sound-absorbing cotton 4. Compared with traditional partition wall structures, it can not only reduce weight but also improve sound insulation effect.

[0028] The wall 1 has several weight-reducing cavities 7 inside. The weight-reducing cavities 7 are circular and are distributed linearly at equal intervals along the height of the wall 1. The weight-reducing cavities 7 can effectively reduce the overall weight of the wall 1 to prevent the excessive weight of the wall 1 from causing additional pressure on the building's load-bearing structure.

[0029] The slots 2 are C-shaped and symmetrically distributed at the top and bottom of the front face of the wall 1. The thickness of the light steel keel 3 is equal to the width of the inner wall of the slot 2, and the height of the light steel keel 3 is equal to the distance between the inner walls of the two slots 2. The light steel keel 3 can be fixedly installed between the two slots 2 by snap-fit ​​without the need for bolts or other fasteners. The light steel keel 3 can be disassembled by sliding it out of the slot 2 so that the partition wall structure can be transported to the designated location for on-site assembly. In addition, after the light steel keel 3 is fixedly installed between the two slots 2 by snap-fit, a cavity will be left between the light steel keel 3, the wall 1, and the sound insulation felt 5. At this time, the air elasticity in this cavity can further attenuate the sound waves to enhance the sound insulation effect.

[0030] The front face of the wall 1 is provided with several wiring grooves 8, and the side walls of the light steel keel 3, sound insulation felt 5 and gypsum board 6 are provided with several lead wire grooves 9. The number of lead wire grooves 9 and wiring grooves 8 are the same, and the center of each lead wire groove 9 corresponds one-to-one with the center of each wiring groove 8. When wiring is required, the wire can be passed through the lead wire groove 9, and then the wire is passed from one end of the wiring groove 8 and out from the other end. Therefore, wiring and routing can be achieved without drilling on the surface of the wall 1, which not only effectively avoids damage to the structure of the wall 1, but also ensures the sound insulation effect of the wall 1.

[0031] The wiring trough 8 has an arc-shaped structure, and several anti-wear pads 10 are provided on the surface of the wall of the wiring trough 8. The anti-wear pads 10 are arc-shaped and are distributed linearly at equal intervals along the length of the wiring trough 8. The anti-wear pads 10 can be made of elastic materials such as rubber and are fixed by adhesives. When the wire passes through the wiring trough 8, the anti-wear pads 10 can play a role in anti-wear protection to prevent the wire from directly contacting the surface of the wall of the wiring trough 8 and causing wear.

[0032] The outer surface of the wall 1 is provided with a sealing ring 11. The sealing ring 11 is rectangular, and its inner wall length and width are equal to the length and width of the wall 1, respectively. The width of the sealing ring 11 is equal to the distance between the wall 1 and the plasterboard 6. The sealing ring 11 can be made of elastic materials such as rubber and is fixed by adhesives. The sealing ring 11 can wrap around the partition wall structure to fill all joints and prevent sound leakage.

[0033] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0034] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0035] The working principle of this utility model is as follows:

[0036] In use, this utility model allows the light steel keel 3 to be fixedly installed between two slots 2 via a snap-fit ​​method, without the need for bolts or other fasteners. The interior of the light steel keel 3 is filled with sound-absorbing cotton 4, which can be made of rock wool, glass wool, polyester fiber, or other sound-absorbing materials. The cotton dissipates sound energy through fiber friction, especially effective against mid-to-high frequency noise. A sound-insulating felt 5 is installed on the front end of the light steel keel 3. This felt 5 can buffer vibrations to block solid-borne sound (such as footsteps or impact sounds). A gypsum board 6 is installed on the front end of the sound-insulating felt 5. The gypsum board 6 is a high-density material that acts as a "mass layer," reflecting and absorbing sound energy through its own weight. This partition wall structure, combining gypsum board 6, sound-insulating felt 5, and sound-absorbing cotton 4, not only reduces weight compared to traditional partition wall structures but also improves sound insulation. Several weight-reducing cavities are provided inside the wall 1. 7. Multiple weight-reducing cavities 7 can effectively reduce the overall weight of the wall 1, preventing excessive weight of the wall 1 from causing additional pressure on the building's load-bearing structure. When wiring is required, the wire can be passed through the lead-in groove 9, then the wire is inserted from one end of the wiring groove 8 and exited from the other end, thus eliminating the need for drilling on the surface of the wall 1 to achieve wiring and routing. This not only effectively avoids damage to the structure of the wall 1, but also ensures the sound insulation effect of the wall 1. The light steel keel 3 can be disassembled by sliding it out of the slot 2, so that the partition wall structure can be transported to the designated location for on-site assembly. In addition, after the light steel keel 3 is fixedly installed between the two slots 2 by snap-fit, a cavity will be left between the light steel keel 3, the wall 1, and the sound insulation felt 5. At this time, the air elasticity in this cavity can further attenuate sound waves to enhance the sound insulation effect.
