Description

Technical Field

[0001] This invention relates to the field of building facilities technology, and in particular to a high sound insulation autoclaved aerated concrete partition wall system and construction method. Background Technology

[0002] With the development of the times, prefabricated lightweight partition walls are gradually replacing traditional masonry walls and cast-in-place wall systems, becoming a common partition wall system in prefabricated buildings such as hotels, office buildings, hospitals, and high-end residences. For buildings with high requirements for the indoor physical environment, especially noise-sensitive spaces such as high-end office buildings, star-rated hotels, hospital wards, and high-quality residences, the sound insulation between rooms in hospitals and hotels must reach 50 dB according to the requirements of the "Code for Sound Insulation Design of Civil Buildings." However, some prefabricated lightweight partition walls often fail to meet the standard's sound insulation requirements due to their poor sound insulation performance. On the other hand, lightweight partition wall systems that meet high sound insulation requirements, such as lightweight thin-panel composite walls, produce a strong hollow sound when struck, leading to a decline in the living experience. Summary of the Invention

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0031] The following is combined Figures 1-4 This invention describes the high sound insulation autoclaved aerated concrete partition wall system and construction method provided by the present invention.

[0032] In view of the problems existing in the prior art, the purpose of this invention is to provide a lightweight wall structure with high sound insulation performance and its construction method. The wall system has high sound insulation performance, fire resistance and is dense when tapped, without making hollow sounds, which can improve the living experience of residents.

[0033] Specifically, please refer to Figures 1-2This invention provides a high-sound-insulating autoclaved aerated concrete (AAC) partition wall system, comprising a first partition wall, a mesh fiber composite layer, an air layer, and a second partition wall. Both the first and second partition walls are composed of multiple AAC strips, each strip having C-shaped grooves on both sides, with corresponding C-shaped grooves between adjacent strips. It should be noted that in the technical solution provided by this invention, the first partition wall is the exterior wall, and the second partition wall is the interior wall. The density of the first partition wall is greater than that of the second partition wall, with both partition walls having a density of 650-750 kg / m³. 3 The thickness is 50mm to 100mm, and the compressive strength is greater than 5MPa.

[0034] Please see Figures 3-4 The mesh fiber composite layer is placed between the first and second partition walls, forming an air gap. In actual construction, pipelines can be installed in this air gap and fixed to the mesh fiber composite layer, enabling flexible pipeline placement and separation from the building structure, thus improving construction efficiency and quality. Specifically, the mesh fiber composite layer comprises multiple staggered panels forming a mesh, which is filled with fibers. The fibers within the mesh enhance the wall's sound insulation and fire resistance.

[0035] The high sound insulation autoclaved aerated concrete partition wall system provided by this invention has high sound insulation performance. Compared with traditional autoclaved aerated concrete partition walls, the sound insulation performance is improved by 15-20% under the premise of the same thickness. At the same time, it has good thermal insulation, durability and fire resistance. In addition, by setting an air layer, pipelines can be flexibly installed in it to achieve pipeline separation.

[0036] Furthermore, in the technical solution provided by this invention, the material of the clamping plate is fiber-reinforced synthetic resin with a tensile strength of not less than 300 MPa. Synthetic resin possesses excellent vibration isolation performance, as well as good mechanical properties and thermal insulation and fireproofing properties. Since the mesh is filled with fibers, each mesh is equipped with a baffle, which has a certain thickness of not less than 5 mm. Generally, two baffles are used, which can compress and limit the fibers within the mesh, achieving a composite confinement effect. It should be noted that the mesh shape can be various, such as square, circular, or triangular. In an optional embodiment, the mesh shape is quadrilateral, with a side length of 200 mm-400 mm. Correspondingly, the baffles can be quadrilateral or circular; this invention does not limit this.

[0037] Specifically, the fibers can be either rock wool or glass wool, both of which have good sound insulation and fireproofing properties. If rock wool is used, its bulk density should not be less than 140 kg / m³. 3 If glass wool is used, its bulk density should not be less than 48 kg / m³.3 The thickness of the fiber filling the grid is slightly less than the width of the plywood, so as to ensure that the fiber layer does not come into contact with the first partition wall.

[0038] Based on the above-mentioned high sound insulation autoclaved aerated concrete partition wall system, the present invention also provides a construction method for the high sound insulation autoclaved aerated concrete partition wall system, including:

[0039] S100, Construct the first partition wall, the mesh fiber composite layer, and the second partition wall in sequence;

[0040] S200. Interface treatment is performed at the joint between the first and second partition wall panels.

[0041] S300. Install a self-adhesive sealing strip in the second joint of the second partition wall, smooth it with the wall surface after caulking, and install rock wool and PE rods in sequence at the connection between the second partition wall and the main structure.

[0042] S400. Apply polymer membrane material to all gaps on the interior side of the second partition wall;

[0043] S500. A self-adhesive sealing strip is installed in the first joint of the first partition wall, and an EPDM rubber foam sealing strip is installed at the connection between the first partition wall, the mesh fiber composite layer and the main structure.

[0044] S600, Cementing and plastering are performed on the side of the first partition wall away from the mesh fiber composite layer.

[0045] It should be noted that connectors are provided at both ends of the first partition wall, the mesh fiber composite layer, and the second partition wall for connection to the main building structure. These connectors can be screws, reinforcing bars, brackets, etc., and a rubber pad is provided at the connection point between the connector and the main building structure. In the technical solution provided by this invention, the upper and lower ends of the mesh fiber composite layer have connection holes for connection to the main structure via screws. It should be noted that an air layer exists between the second partition wall and the mesh fiber composite layer, which can be used for pipeline installation. The first partition wall and the mesh fiber composite layer are tightly fitted without connection, and the fibers in the mesh do not contact the first partition wall. The gaps between the first partition wall, the mesh fiber composite layer, and the main structure need to be sealed with EPDM rubber foam sealing strips.

[0046] Furthermore, in order to ensure good sound insulation performance of the wall system, the joints of the first and second panels are staggered, with a stagger distance of not less than 150mm.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
