Description

Technical Field

[0001] This utility model relates to the field of building materials technology, and more specifically to a soundproof brick and wall panel structure. Background Technology

[0002] Lightweight bricks are widely favored due to their practicality, low cost, and good processing and construction performance. They can effectively reduce the amount of concrete or solid clay bricks used, thereby reducing costs. Lightweight bricks are bulky but lightweight, effectively reducing the labor intensity of construction workers, improving construction efficiency, shortening the construction period, and further reducing construction costs. In recent years, with the continuous improvement of people's living standards, the requirements for building materials have also gradually increased. Noise pollution from external environments such as road construction, building work, and traffic has seriously threatened human physical and mental health, thus increasing the demand for sound insulation in buildings. Lightweight sound-insulating bricks must maintain sound insulation while also being lightweight and of moderate thickness. For example, Chinese Patent Publication No. CN105756265A discloses a lightweight sound-insulating brick comprising a surface layer and a filler. The filler consists of five layers: a core layer, a fixing layer, and an air layer, arranged from the center outwards. The core layer is made of foam or rock wool. The fixing layer and surface layer are made of foamed cement, sand, and dried mulberry branches in a mass ratio of 3:2:1 to 2:1:1. This patented lightweight sound-insulating brick structure offers some sound insulation, but its disadvantages include a complex overall structure and inconvenient manufacturing, requiring further structural improvement. Summary of the Invention

[0003] The purpose of this utility model is to provide a lightweight sound-insulating brick that is simple in structure, stable and reliable, easy to manufacture, and has high production efficiency in order to overcome the shortcomings of the existing technology.

[0004] Another objective of this invention is to provide a wall panel structure.

[0005] The present invention achieves the above-mentioned objective by adopting the following technical solution: a lightweight sound-insulating brick, characterized in that it comprises a gypsum brick body, the interior of which contains a large number of micro-interconnected pores, which have a good vibration damping effect for bass frequency reduction; the gypsum brick body is provided with at least one row of sound-absorbing grooves, and each row of sound-absorbing grooves contains more than three sound-absorbing grooves.

[0006] As a further explanation of the above solution, the sound-absorbing groove is filled with glass wool. Because the internal fibers of glass wool are loose and interwoven, there are also a large number of micro-structured pores. When sound waves are incident on the surface of the material, the sound waves can enter the interior of the material through the pores, causing the air molecules in the pores to vibrate. Due to the viscous resistance of the air and the friction between the air molecules and the pore walls, the sound energy is converted into frictional heat energy and absorbs the sound, achieving a good sound absorption and noise reduction effect.

[0007] Furthermore, the glass wool is detachably placed in the sound-absorbing groove, and the glass wool is either yellow or white.

[0008] Furthermore, the sound-absorbing groove is a rectangular through groove.

[0009] Furthermore, the three or more sound-absorbing grooves are arranged in an array, with a gap between adjacent sound-absorbing grooves.

[0010] Furthermore, the sound-absorbing grooves are rectangular, and each sound-absorbing groove is arranged in a 1×4 or 2×3 array.

[0011] Furthermore, the left and right ends of the gypsum brick are respectively provided with corresponding protrusions and concave positions. In two adjacent gypsum bricks, the protrusion of gypsum brick one and the concave position of gypsum brick two are matched to improve the stability of the wall.

[0012] A wall panel structure, characterized in that it comprises a rough wall panel, a putty layer, and a paint decorative layer, wherein the rough wall panel is made of multiple lightweight sound-insulating bricks, the putty layer is applied to the surface of the rough wall panel, and the paint decorative layer is applied to the outside of the putty layer.

[0013] Furthermore, the rough wall panel is reinforced with L-shaped tie bars.

[0014] Furthermore, square steel is used to reinforce the lintel position of the unfinished wall panel.

[0015] Furthermore, the thickness of the putty layer is 2-5mm, and the thickness of the rough wall panel is 100 or 200mm.

[0016] The beneficial effects that can be achieved by adopting the above-mentioned technical solution in this utility model are as follows.

[0017] 1. This utility model uses gypsum bricks with numerous interconnected micropores, which effectively reduce noise frequency and damping. At least one row of sound-absorbing grooves is incorporated into the gypsum brick, with each row containing three or more grooves. These grooves can be filled with glass wool. Noise enters the grooves through the pores of the gypsum brick and is continuously reflected, scattered, and rubbed within the pores of the glass wool, resulting in continuous energy loss and excellent sound absorption. A 100mm thick lightweight sound-absorbing brick filled with glass wool achieves a sound insulation level greater than 41 decibels; even without filling, a 200mm thick lightweight sound-absorbing brick achieves a sound insulation level greater than 43 decibels, far exceeding the sound insulation performance of existing products.

[0018] 2. The lightweight sound-insulating bricks used in this utility model significantly improve the stability of the wall panel by adding L-shaped tie bars when building the wall. This results in high construction efficiency, high fire resistance, high wall surface flatness, and compatibility with any material. Attached Figure Description

[0028] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings, making the technical solution and beneficial effects of this utility model clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] like Figures 1-2 As shown, this utility model is a lightweight sound-insulating brick, including a gypsum brick body 1. The main materials of the gypsum brick body 1 are high-temperature calcined gypsum powder, slag powder, and reinforcing fiber material, with the reinforcing fiber material being glass fiber. The density of each cubic meter of finished wall is 550 kg / m³. After construction, no cement mortar plastering layer is required; putty can be applied directly. Due to the large number of interconnected micropores inside the gypsum brick body, it has a good vibration damping effect for reducing noise frequency. The two ends of the gypsum brick body 1 are respectively provided with corresponding protrusions 1-1 and concave positions 1-2. In two adjacent gypsum brick bodies, the protrusions of gypsum brick body 1 and the concave positions of gypsum brick body 2 fit together, improving the stability of the constructed wall. The gypsum brick body is provided with at least one row of sound-absorbing grooves, each row containing three or more sound-absorbing grooves 1-3, which are arranged in an array, with a gap between adjacent sound-absorbing grooves 1-3. Testing revealed that 100mm thick lightweight sound-absorbing bricks provided 39 decibels of sound insulation, while 200mm thick lightweight sound-absorbing bricks provided over 43 decibels. To further enhance sound insulation, glass wool 2 can be filled into the sound-absorbing grooves 1-3. Noise enters through these grooves and is continuously reflected, scattered, and rubbed within the pores and fibers of the glass wool, resulting in continuous energy loss and excellent sound absorption. Testing showed that 100mm thick lightweight sound-absorbing bricks containing glass wool provided over 41 decibels of sound insulation.

[0030] In this embodiment, the sound-absorbing grooves 1-3 are arranged in a 2×3 array, and the shape of the sound-absorbing grooves 1-3 is a quadrangular prism through groove, taking into account both the convenience of product processing and the sound absorption effect. In some embodiments, the sound-absorbing grooves 1-3 are arranged in a 1×2 array (e.g. Figure 2 (as shown) or other forms of array, the sound-absorbing grooves 1-3 are rectangular through grooves, as long as they can hold glass wool to enhance the sound absorption effect.

[0031] In this embodiment, the glass wool 2 is preferably yellow, which meets the sound absorption requirements and has a relatively low cost. In some embodiments, the glass wool is white, but this is not limited to this embodiment.

[0032] Furthermore, since the glass wool 2 is removable and placed within the sound-absorbing grooves 1-3, its application is simple: just insert the glass wool 2 of the appropriate shape into the sound-absorbing grooves 1-3 without any additional curing or other operations, making implementation convenient. The shape of the glass wool 2 should match the shape of the sound-absorbing groove to achieve better sound insulation and noise reduction effects.

[0033] Combination Figure 3 , Figure 4 As shown, during construction, the wall serves as a soundproof wall panel, structurally comprising a rough wall panel 3, a putty layer 4, and a paint finish 5. In this embodiment, both sides of the rough wall panel are provided with a putty layer 4 and a paint finish 5. The rough wall panel is constructed from multiple lightweight soundproof bricks, with the putty layer 4 applied to the surface of the rough wall panel 3, and the paint finish 5 applied over the putty layer 4. The rough wall panel is equipped with structural columns 6, which are steel square tube structures, and L-shaped tie bars 7 are provided on the sides of the structural columns 6 for reinforcement. At the doorway, the lintel of the rough wall panel is reinforced with square steel. The thickness of the unfinished wall panels is 100mm or 200mm. With a thickness of 100mm, it is suitable for ordinary partition walls without insulation, achieving a sound insulation coefficient of 39 decibels. It is suitable as a fireproof partition wall for ordinary office partitions, factory firewalls, apartments, and other non-load-bearing partitions. With insulation, the sound insulation coefficient is 41 decibels. Combined with sound-absorbing cotton, it is suitable for hotel rooms, KTVs, bars, high-end offices, hospitals, schools, and other places with sound insulation requirements. With a thickness of 200mm, without insulation, the sound insulation coefficient is 43 decibels. It is suitable for fireproof partition walls, used in apartment buildings, factories, and other non-load-bearing partitions. With insulation, the sound insulation coefficient is 48 decibels. Combined with sound-absorbing cotton, it is suitable for high-end hotel rooms, bars, electronic music KTVs, and other places with high sound insulation requirements.

[0034] The following is a comparison of wall material performance (100mm thickness + filling).

[0035]

[0036] The construction process utilizes I-beam stacking to prevent cracking, resulting in a construction speed three times faster than aerated concrete blocks and red bricks. No base coat is required, significantly improving project efficiency. The material is lightweight, only half the volume of plastered aerated concrete blocks. Overlapping bricks at intersections increases strength, and the fire resistance is high; a 10cm wall can withstand fire for up to 4 hours. The wall surface is highly flat and compatible with any material. According to the airborne sound insulation test report, the test wall was constructed of lightweight sound-insulating bricks, with each block 100mm thick. The joints between blocks and around the perimeter were filled with adhesive plaster, and a 3mm thick layer of putty was applied to both sides of the wall. The apparent density of the lightweight sound-insulating bricks was 830kg / m³. 3 According to GB / T19889.3-2005 and GB / T50121-2005 standards, the test sample (wall thickness 156mm, apparent density of blocks 980kg / m³) was tested. 3 The airborne sound weighted sound insulation is Rw(C;Ctr) = 43 (-1;-4) dB, which is a high sound insulation coefficient.

[0037] Compared with the prior art, this utility model uses several sound-absorbing grooves set in the gypsum brick body, and the sound-absorbing grooves are filled with glass wool. Noise enters through the sound-absorbing grooves and is continuously reflected, scattered and rubbed in the pores and fibers of the glass wool, and the energy is continuously lost, which achieves a very good sound absorption effect and is lightweight. When stacking the wall, the stability of the wall panel is greatly improved by adding structural columns and L-shaped tie bars. It has high construction efficiency, high fire resistance, high wall surface flatness and is compatible with any material.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
