Description

Technical Field

[0001] The utility model relates to the technical field of assembled exterior wall structures, in particular to an assembled exterior wall structure with good sound insulation effect. Background Art

[0002] Prefabricated exterior walls are a design and construction method for building wall structures, characterized by prefabricating wall components in a factory before on-site assembly and installation. Publication No. CN212176180U discloses a prefabricated exterior wall comprising exterior wall panels. Several of these panels are designed to be mounted on a keel. The panels are provided with positioning members and positioning slots at their upper and lower ends. In two adjacent exterior wall panels, the positioning members of one panel are designed to fit within the positioning slots of the other panel, with the positioning members abutting the sidewalls of the positioning slots at both ends, parallel to the panels and horizontally. The assembled exterior wall has positioning parts and positioning grooves on two upper and lower adjacent exterior wall panels, which are interlocked to achieve the positioning of the exterior wall panels and the effect of a single person cooperating with a lifting machinery to complete the installation of the exterior wall panels. However, this assembled exterior wall, like most exterior walls currently on the market, is not equipped with a sound insulation mechanism. When the sound insulation effect is poor, the external noise cannot be effectively weakened when passing through the wall, which will lead to a worse living effect for the residents indoors, affecting their daily living and rest, and needs to be improved. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems raised in the above background technology.

[0004] The utility model adopts the following technical solution: an assembled exterior wall structure with good sound insulation effect, comprising an outer protective layer, a sound-absorbing layer fixedly installed on the back side of the outer protective layer, sound-absorbing holes provided on the surface of the sound-absorbing layer, a sound-absorbing groove provided on the inner side of the sound-absorbing layer, a sound-blocking block fixedly installed on the inner side of the sound-absorbing groove, a sound insulation board layer fixedly installed on the back side of the sound insulation board layer, a heat-insulating layer fixedly installed on the back side of the heat-insulating layer, a reinforcement layer fixedly installed on the back side of the heat-insulating layer, and an inner protective layer fixedly installed on the back side of the reinforcement layer.

[0005] Preferably, the outer protective layer is made of marble, and the sound-absorbing layer is made of polyurethane foam. Marble has a high density and a smooth surface, effectively isolating external noise while also offering excellent weather resistance and durability. Polyurethane foam has excellent sound absorption properties, effectively absorbing sound and converting it into weak heat energy, thereby reducing sound reflection and transmission.

[0006] Preferably, the sound insulation layer is made of gypsum board, and the insulation layer is made of polystyrene board. Gypsum board has excellent sound insulation properties, effectively blocking the transmission of sound and reducing the interference of indoor and outdoor noise. Polystyrene board has excellent thermal insulation properties, effectively reducing the conduction and convection of temperature inside and outside the building, improving the building's thermal insulation effect, reducing energy consumption, and saving energy costs.

[0007] Preferably, the reinforcement layer is made of steel, and the inner protective layer is made of PVC. Steel, with its excellent strength and rigidity, can effectively increase the building's load-bearing capacity and structural stability, enhancing its resistance to natural disasters such as earthquakes and wind. PVC, with its excellent waterproof properties and resistance to moisture and water absorption, can effectively prevent water vapor penetration and protect the building structure from water damage.

[0008] Preferably, a connecting ear A is fixedly mounted on the side of the inner protective layer, and a connecting ear B is fixedly mounted on the side of the outer protective layer, with an insert inserted into the inner side of the connecting ear A. The arrangement of the connecting ears A, B, and insert can effectively improve the installation efficiency of the assembled exterior wall structure.

[0009] Preferably, the connecting lugs A, B, and the insert are all made of carbon steel. Carbon steel has good workability, strength, and durability, is suitable for the load-bearing requirements of most building structures, and is relatively inexpensive and economical.

[0010] Compared with the prior art, the advantages and positive effects of the present invention are:

[0011] 1. In the present invention, by arranging an outer protective layer, a sound-absorbing layer, sound-absorbing holes, sound-absorbing grooves, sound-blocking blocks, sound-insulating board layers, a thermal insulation layer, a reinforcement layer, and an inner protective layer, the impact of external noise on the interior can be reduced while ensuring the thermal insulation performance of the building. The noise can be effectively weakened when passing through the wall to ensure the rest and daily living of the residents.

[0012] 2. In the present invention, by setting connecting ears A, connecting ears B, and inserts, the mortise and tenon structure is used to quickly connect and install the assembled exterior walls, which not only improves the installation efficiency, but also effectively improves the maintenance efficiency during the later disassembly and maintenance process of the assembled wall.

A reinforcement layer 8 is fixedly installed on the back of the thermal insulation layer 7, and the material of the reinforcement layer 8 is steel. An inner protective layer 9 is fixedly installed on the back of the reinforcement layer 8, and the material of the inner protective layer 9 is PVC board. The PVC board has good corrosion resistance and is not affected by chemicals, acids and alkalis. It is suitable for use under various environmental conditions and extends the service life of the building structure.

[0025] Example 2

[0026] See also Figure 1 、 2 4. A connecting ear A10 is fixedly installed on the side of the inner protective layer 9, and a connecting ear B11 is fixedly installed on the side of the outer protective layer 1. An insert 12 is inserted on the inner side of the connecting ear A10. The connecting ear A10, the connecting ear B11, and the insert 12 are all made of carbon steel. Compared with the traditional connection method, the mortise and tenon structure usually reduces additional connecting parts, such as bolts, screws, etc., thereby reducing the use and cost of auxiliary materials, which not only improves the installation efficiency of the prefabricated exterior wall, but also facilitates the subsequent disassembly and maintenance work.

[0027] Working principle: During installation, first install and fix the first set of assembled exterior walls, then adjust the position of the assembled exterior walls of the other set so that the connecting ears B11 on its side are close to the connecting ears A10 of the first set, and then insert the insert strips 12 from top to bottom into the mortise left after the connecting ears B11 and A10 are fitted together. At this time, the connection between the assembled exterior walls is completed. When noise propagates, the noise will be transmitted through the outer protective layer 1 to the sound-absorbing layer 2, and then the noise will enter the inner side of the sound-absorbing groove 4 through the sound-absorbing hole 3. During this process, the sound-blocking block 5 will intercept and weaken the noise, and then the weakened noise will be blocked again by the sound insulation board layer 6, thereby achieving excellent sound insulation effect, which can bring a higher living experience to the residents.
