Description

Technical Field

[0001] This utility model relates to the field of partition wall structure technology, and in particular to a building partition wall structure with high sound insulation. Background Technology

[0002] A partition wall is a wall used to separate different residential units within the same building. The main functions of a partition wall are to provide sound insulation, fire protection, heat insulation, and privacy protection, ensuring the independence and comfort of each residential unit. In multi-family residences, partition walls usually use specific building materials and technologies to ensure relative quiet and safety between residents.

[0003] Most existing partition walls are two to three layers high, with a keel supporting the middle and plasterboard covering the sides, with sound insulation material filled in between. This simple structure has limited sound insulation effect. Moreover, the light steel keel plasterboard wall has low material density and rigid connection, which easily forms sound bridges, causing impact sound to be transmitted through the keel and floor. Therefore, those skilled in the art have provided a building partition wall structure with high sound insulation to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a building partition wall structure with high sound insulation. This structure allows polyester fiber sound-absorbing cotton and glass wool to contact the ground, thereby avoiding sound transmission caused by the keel. The partition wall composed of multiple sound insulation structures has a better sound insulation effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a building partition wall structure with high sound insulation, comprising two main light steel keels, four secondary light steel keels, two gypsum boards, and two polyester fiber sound-absorbing cottons. Fiberboards are fixedly installed on opposite ends of the two polyester fiber sound-absorbing cottons, sound insulation boards are fixedly installed on opposite ends of the two fiberboards, and glass wool is fixedly installed on opposite ends of the two gypsum boards.

[0006] Furthermore, brick wall panels are fixedly installed on opposite ends of the two gypsum boards, and outer panels are fixedly installed between the two ends of the two brick wall panels.

[0007] Furthermore, the two glass wools are respectively fixedly installed on opposite ends of the two gypsum boards.

[0008] Furthermore, the two polyester fiber sound-absorbing cottons are respectively arranged on both sides of the two main light steel keels, and the bottom of the polyester fiber sound-absorbing cottons extends beyond the bottom end of the main light steel keel.

[0009] Furthermore, the four secondary light steel keels are respectively installed inside the two glass wools, and the bottom of the glass wools extends beyond the bottom end of the secondary light steel keels. The four secondary light steel keels are respectively fixedly connected to the two gypsum boards.

[0010] This utility model has the following beneficial effects:

[0011] 1. This utility model proposes a sound-insulating partition wall structure for buildings. The partition wall is supported by main light steel keel and secondary light steel keel. Polyester fiber sound-absorbing cotton is wrapped around the outer ends of the two main light steel keels, and glass wool is wrapped around the outer ends of the secondary light steel keel. The combination structure of the main and secondary light steel keels makes the partition wall more durable. Moreover, neither the main nor secondary light steel keel of the partition wall directly contacts the ground. Instead, the polyester fiber sound-absorbing cotton and glass wool contact the ground, thereby avoiding sound transmission caused by the keel.

[0012] 2. The present invention proposes a building partition wall structure with high sound insulation. The partition wall is composed of multiple layers, from the middle to the outside: polyester fiber sound-absorbing cotton, fiberboard, sound insulation board, glass wool and gypsum board. The partition wall composed of multiple sound insulation structures has better sound insulation effect. Moreover, there is a gap between two polyester fiber sound-absorbing cotton layers, which forms a hollow area, thereby further improving the sound insulation effect. Attached Figure Description

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figure 1 - Figure 4 The present invention provides an embodiment of a building partition wall structure with high sound insulation, comprising two main light steel keels 6, four secondary light steel keels 7, two gypsum boards 5, and two polyester fiber sound-absorbing cotton 1. Fiberboard 9 is fixedly installed on the opposite end face of the two polyester fiber sound-absorbing cotton 1, and sound insulation board 2 is fixedly installed on the opposite end face of the two fiberboard 9. Glass wool 4 is fixedly installed on the opposite end face of the two gypsum boards 5.

[0021] Brick wall panels 3 are fixedly installed on opposite ends of two gypsum boards 5. Outer panels 8 are fixedly installed between the two ends of the two brick wall panels 3. Two glass wools 4 are fixedly installed on opposite ends of two gypsum boards 5. Two polyester fiber sound-absorbing cottons 1 are installed on both sides of two main light steel keels 6. The bottom of the polyester fiber sound-absorbing cottons 1 extends beyond the bottom of the main light steel keel 6. Four secondary light steel keels 7 are installed inside the two glass wools 4. The bottom of the glass wools 4 extends beyond the bottom of the secondary light steel keels 7. The four secondary light steel keels 7 are fixedly connected to the two gypsum boards 5.

[0022] Specifically, the partition wall is supported by two main light steel keels 6 in the middle, increasing the overall strength of the partition wall. Polyester fiber sound-absorbing cotton 1 is wrapped around the outer ends of the two main light steel keels 6. Polyester fiber sound-absorbing cotton 1 is a porous sound-absorbing material made primarily of polyester fiber, which has a significant effect on absorbing mid-to-high frequency sound waves. Gaps are created between the two polyester fiber sound-absorbing cotton 1 pieces, making sound transmission even more difficult. Fiberboard 9 supports the outer ends of the two polyester fiber sound-absorbing cotton 1 pieces. The tops of both the main and secondary keels are connected to the floor slab. Fiberboard 9 is composed of sound-absorbing fibers and is attached to the polyester fiber sound-absorbing cotton 1, making the installation more secure. Fiberboard 9 connects to sound insulation board 2, which is made of high-density material and effectively reduces the transmission of airborne and structural sound. Sound insulation board 2 connects to glass wool 4, an inorganic fiber material made primarily of glass, which has excellent thermal insulation, sound insulation, and fire resistance. Yes, a secondary light steel keel 7 is installed inside the glass wool 4 to increase the overall strength of the partition wall, making it more durable. The glass wool 4 is wrapped with gypsum board 5, which is a lightweight building board made of building gypsum as the main raw material, with the addition of fiber, additives and water to form a slurry, which is then shaped, solidified and dried. Gypsum board 5 has the advantages of being lightweight, fireproof, soundproof and easy to construct. Finally, a decorative brick wall panel 3 is installed on the outer end of the gypsum board 5. This brick wall panel 3 is a panel with bricks drawn on it, not an actual brick wall, to make the partition wall look more beautiful. The entire sound insulation structure is wrapped in the brick wall panel 3 and the outer panel 8. Moreover, the main light steel keel 6 and the secondary light steel keel 7 of this partition wall do not directly contact the ground. Instead, the polyester fiber sound-absorbing cotton 1 and the glass wool 4 contact the ground, so that the keel and the floor slab are in indirect contact through elastic materials, thus avoiding sound transmission caused by the keel. In addition, the sound insulation effect of the partition wall is better through multiple sound insulation materials.

[0023] Working principle: This partition wall consists of multiple layers. Two main light steel keels 6 support the middle of the wall. Polyester fiber sound-absorbing cotton 1 is wrapped around the outer ends of the two main light steel keels 6, with gaps between them. Fiberboard 9 supports the outer ends of the two polyester fiber sound-absorbing cotton 1s, connecting the fiberboard 9 to the sound insulation board 2, which in turn connects to glass wool 4. Secondary light steel keels 7 are installed inside the glass wool 4, which is then wrapped with gypsum board 5. Finally, decorative brick wall panels 3 are installed on the outer ends of the gypsum board 5. The entire sound insulation structure is encased in brick wall panels 3 and outer panels 8. Furthermore, neither the main light steel keels 6 nor the secondary light steel keels 7 directly contact the ground; instead, the polyester fiber sound-absorbing cotton 1 and glass wool 4 are in contact with the ground, thus preventing sound transmission caused by the keels.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
