Description
Technical Field
[0001] This invention relates to the field of prefabricated buildings, specifically to a prefabricated lightweight soundproof wall and its connectors. Background Technology
[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories are processed and manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods.
[0003] With the vigorous development and continuous promotion of prefabricated decoration technology, soundproof walls are also gradually adopting prefabricated installation methods. However, existing prefabricated soundproof walls still use traditional prefabricated wall technology, without focusing on sound insulation optimization, resulting in poor sound insulation effect and inconvenient installation. Publication No. CN218522001U discloses a prefabricated wall structure that facilitates the installation of sound insulation panels and cotton through the cooperation of sound insulation boards, sound insulation cotton, a second sliding strip, and a second sliding groove, thereby improving the sound insulation effect. During installation, the locking strip needs to be inserted into the gap between the first and second connecting parts, and the second sliding strip needs to be inserted into the second sliding groove to move the sound insulation board to the installation position. Since this requires a large installation space on the construction site, it is not suitable for direct assembly and requires subsequent assembly to fix the wall. Therefore, a prefabricated lightweight soundproof wall and its connecting parts are proposed to facilitate the assembly of the soundproof wall and improve the sound insulation effect. Summary of the Invention

The support plates are arranged in pairs, and two connecting plates are provided, one at the top end and the other at the bottom end of one of the support plates. The other support plate is fixedly connected to the connecting plate by screws. A reinforcing strip is fixedly connected to one side of the support plate, and a pressure plate is provided on the other side of the support plate. The surface of the pressure plate is provided with fixing holes, and limit holes are provided on the surface of the pressure plate above and below the fixing holes.

[0007] Preferably, the reinforcing strip is disposed in the middle of the support plate in the width direction, and the reinforcing strip is integrally formed with the support plate.
[0008] Preferably, the height of the connecting column is greater than the thickness of the pressure plate, and the two ends of the pressure plate are provided with support platforms so that the distance between the pressure plate and the support plate is not less than 3mm, and the pressure nail is interference-fitted with the pressure plate.
[0009] Preferably, the fixing hole is provided with through holes on the left and right sides that are adapted to the baffle, the mounting hole is a countersunk hole, and the support plate is provided with a sound insulation strip on the side near the reinforcing strip.
[0010] A prefabricated lightweight soundproof wall includes the aforementioned connectors. The connectors are vertically arranged and connect the ground and the ceiling. Multiple connectors are provided, and wall bricks are placed between adjacent connectors. The wall bricks are stacked along the length of the connectors. One side of the connector and one side of the wall brick are located in the same plane. The left and right adjacent wall bricks are in contact with each other. A sound insulation cotton layer is provided on one side of the wall brick, and a sound insulation board is provided on one side of the sound insulation cotton layer. The sound insulation cotton layer is fixed to one side of the wall brick by pressure nails, and the sound insulation board is fixed to one side of the wall brick by fasteners.
[0011] The wall brick includes a brick body with a cavity inside. Each of the four corners of the brick body has a connecting groove adapted to the connector. The two sides of the brick body have protrusions, and the two ends of the brick body have semi-circular grooves with sealing strips inside.

[0016] The present invention adopts the above technical solution, and the beneficial effects include:
[0017] This type of prefabricated lightweight soundproof wall is mainly constructed of stacked bricks, which are reinforced with connectors to ensure the stability of the wall. The bricks are made of foam bricks, which are lightweight and sound-insulating. Raised studs on the surface and internal cavities prevent sound from being transmitted evenly within the bricks, further improving sound insulation. Sealing strips are installed in the semi-circular grooves to solve the problem of gaps between the stacked bricks affecting sound insulation. A layer of sound-insulating cotton and sound-insulating boards are added to the wall surface, significantly enhancing the sound insulation effect.
[0018] The connectors of this type of prefabricated lightweight soundproof wall adopt an integrated structure of support plate and reinforcing strip, connecting the ground and ceiling. This provides effective lateral support for the wall bricks, improving the stability of the wall. Simultaneously, because the connectors are located at both ends of the wall bricks, they provide excellent positioning during installation, improving assembly efficiency. The pressure nails on the pressure plate surface ensure timely fixation of the sound insulation cotton layer, facilitating its secure installation and increasing efficiency. The fasteners connect to the soundproof panels, allowing for pre-assembly via the fasteners and fixing holes, improving stability during installation and simplifying the process.

Detailed Implementation
[0029] The present invention will be further described below with reference to the accompanying drawings.
[0030] Example 1: Please refer to Figure 1-9 This invention provides a technical solution: a connector for a prefabricated lightweight soundproof wall, comprising a support plate 101 and a connecting plate 102. The support plates 101 are arranged in pairs and can be cut according to the distance between the ground and the ceiling during use, and can also be extended by welding. Two connecting plates 102 are provided, one at the top end and the other at the bottom end of one of the support plates 101, and are fixed by welding. One is set on the ground and the other on the ceiling. The surface of the connecting plate 102 is provided with matching mounting holes. The other support plate 101 is fixedly connected to the connecting plate 102 by screws. A reinforcing strip 104 is fixedly connected to one side of the support plate 101. The reinforcing strip 104 is located in the middle of the width direction of the support plate 101 and is integrally formed with the support plate 101. The support plate 101 is provided with a pressure plate 103 on the other side of the support plate 101. The pressure plate 103 has support platforms at both ends so that the distance between the pressure plate 103 and the support plate 101 is not less than 3mm. The specific distance depends on the thickness of the sound insulation cotton layer. The sound insulation cotton layer is placed between the pressure plate 103 and the support plate 101. The surface of the pressure plate 103 is provided with fixing holes 106. The surface of the pressure plate 103 and the upper and lower sides of the fixing holes 106 are provided with limit holes 108. One side of the pressure plate 103 is provided with a fastener 107 that matches the fixing holes 106. The surface of the pressure plate 103 is also provided with a pressure nail 109. The pressure nail 109 and the pressure plate 103 are interference fit. When the sound insulation cotton layer is laid, the pressure nail 109 is hammered to fix the sound insulation cotton layer.
[0031] Fastener 107 includes a fastener plate 1701 and a baffle plate 1073. A connecting post 1702 is fixedly connected between the fastener plate 1701 and the baffle plate 1073. A limiting post 1076 adapted to a limiting hole 108 is provided on the side of the fastener plate 1701 near the baffle plate 1073. The limiting post 1076 is movably connected to the fastener plate 1701. A spring 1077 is provided between the fastener plate 1701 and the limiting post 1076. A mounting hole 1075 is provided on the surface of the fastener plate 1701. The mounting hole 1075 is a countersunk hole. A fastening hole 1074 is provided in the middle of the fastener plate 1701. The fastening hole 1074 penetrates the connecting post 1702 and the baffle plate 1073. The surface of the support plate 101 is provided with... A fixing hole 110 is provided to match the fastening hole 1074. The buckle plate 1701 is fixed to one side of the sound insulation plate 4 through the mounting hole 1075. The installation interval of the buckle plate 1701 is equal to the interval of the fixing hole 106. When installing the sound insulation plate 4, the sound insulation plate 4 is moved to one side of the pressure plate 103 and the sound insulation plate 4 is pressed so that the limiting post 1076 is pressed into the buckle plate 1701. At this time, the baffle 1073 passes through the fixing hole 106 and the sound insulation plate 4 is moved horizontally so that the limiting post 1076 enters the limiting hole 108, thus realizing the fixation of the sound insulation plate 4. The height of the connecting post 1702 is greater than the thickness of the pressure plate 103, ensuring that the baffle 1073 can pass smoothly through the fixing hole 106.
[0032] The left and right sides of the fixing hole 106 are provided with through holes that are compatible with the baffle 1073, so that the sound insulation plate 4 can be installed from the left and right directions to meet different installation angles. The support plate 101 is provided with a sound insulation strip 105 on the side near the reinforcing strip 104, which improves the sealing between the connector 1 and the wall brick 2 and improves the sound insulation effect. The sound insulation strip 105 is made of rubber or sponge.
[0033] A prefabricated lightweight soundproof wall includes a connector 1 as described above. The connector 1 is vertically arranged and connects the ground and the ceiling. Multiple connectors 1 are provided. Wall bricks 2 are placed between two adjacent connectors 1. The wall bricks 2 are stacked along the length of the connector 1, and adjacent wall bricks 2 are fixed with adhesive. One side of the connector 1 and one side of the wall brick 2 are in the same plane to ensure the flatness of the wall surface. The wall bricks 2 on the left and right are in contact. A sound insulation cotton layer 3 is provided on one side of the wall brick 2, and a sound insulation board 4 is provided on one side of the sound insulation cotton layer 3. The sound insulation cotton layer 3 is fixed to one side of the wall brick 2 by pressure nails 109, and the sound insulation board 4 is fixed to one side of the wall brick 2 by fasteners 107.
[0034] The wall tile 2 includes a brick body 21, with a cavity 22 inside the brick body 21. Sound insulation cotton or foam can be added inside the cavity 22 as needed to improve the sound insulation effect. Each of the four corners of the brick body 21 is provided with a connecting groove 24 that matches the connector 1. The two sides of the brick body 21 are provided with protrusions 23, which make the surface of the wall tile uneven, thereby dispersing the sound propagation path. The two ends of the brick body 21 are provided with semi-circular grooves 25, and sealing strips 28 are provided in the semi-circular grooves 25. When the left and right adjacent wall tiles 2 come into contact through the sealing strips 28, the sealing performance after connection is improved. At the same time, one side of the sealing strip 28 is set as a continuous concave and convex curved surface, which increases the contact area and further improves the sound insulation effect. The sealing strip 28 is made of rubber or sponge material.
[0035] The top of the brick 21 is provided with a protrusion 26, and the bottom of the brick 21 is provided with a groove 27 that matches the protrusion 26. Since the adjacent wall bricks 2 are bonded together, the protrusion 26 and the groove 27 fit together after being stacked, thus avoiding gaps.
[0036] The brick body 21 is made of foam brick. The connecting groove 24, semi-circular groove 25, protrusion 26 and groove 27 are formed by mold making, realizing the one-time molding of the entire wall brick 2, which improves the processing efficiency. Foam brick has the characteristics of being lightweight and soundproof.
[0037] The sealing strip 28 is fixed in the semi-circular groove 25 by adhesive.
[0038] Sound insulation cotton layer 3 and sound insulation board 4 are set on both sides of wall brick 2, and sound insulation board 4 is made of gypsum board. This achieves the installation of sound insulation cotton 3 and sound insulation board 4 on both sides of the wall, further improving the sound insulation effect. In the later decoration, processing can be carried out directly on the surface of gypsum board. Only mesh needs to be hung at the joint of gypsum board to prevent wall cracking, which facilitates the later construction.
