Technical Field

[0001] This utility model relates to the technical field of noise reduction boards for green building construction, specifically a green building construction energy-saving noise reduction board. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction. The location where construction work takes place is called a "construction site" or "building site."

[0003] Noise generated by various equipment and the impact of hammering on objects during construction can affect the lives of nearby residents. To reduce the noise generated during construction, noise reduction panels need to be installed around the construction site.

[0004] However, existing noise reduction panels, which use a single porous cotton filling structure or a single high-density reflective panel structure to block noise, have a weak noise reduction capability and some noise will still diffuse, making it difficult to ensure effective noise isolation and causing serious noise pollution to the outside world to a certain extent.

[0005] Therefore, in view of this, we have studied and improved the existing structure to propose a green building construction energy-saving and noise-reducing board. Utility Model Content

[0006] The purpose of this utility model is to provide an energy-saving and noise-reducing board for green building construction, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a green building construction energy-saving noise reduction board, comprising a noise reduction board body, wherein the noise reduction board body includes a rubber substrate as the base layer of the entire board body, a first porous cotton is fixedly connected to the front side of the surface of the rubber substrate, a second porous cotton is fixedly connected to the rear side of the surface of the rubber substrate, a first foaming layer is fixedly connected to the front side of the surface of the first porous cotton, a second foaming layer is fixedly connected to the rear side of the surface of the second porous cotton, and a surface layer is fixedly connected to the front side of the surface of the first foaming layer and the rear side of the surface of the second foaming layer, wherein a protective film is adhered to the surface of each surface layer.

[0008] Preferably, both the first porous cotton and the second porous cotton are made of rock wool, and the first porous cotton and the second porous cotton form a double sandwich structure in the inner layer of the noise reduction board.

[0009] Preferably, the first foam layer and the second foam layer are made of either PVC foam or polyurethane, and the first foam layer and the second foam layer form a double sandwich structure in the middle layer of the noise reduction board.

[0010] Preferably, the surface layer is made of high-density PC board, and the protective film is made of polypropylene film material.

[0011] Preferably, the outer side of the noise reduction panel is fixedly connected to the same support frame, a rear connecting plate is fixedly installed on the rear side of the left surface of the support frame, and a front connecting plate is fixedly connected to the front side of the right surface of the support frame.

[0012] Preferably, sound insulation pads are fixedly connected to the surfaces of the rear connecting plate and the front connecting plate on the side near the center point of the front and rear of the support frame, and the thickness of the rear connecting plate and the front connecting plate combined with the sound insulation pads is the same as the thickness of the entire support frame.

[0013] Preferably, the front side of the rear connecting plate has a positioning screw hole that penetrates the sound insulation pad, and the entire surface of the front connecting plate has a connecting screw hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the arrangement of a noise-reducing board, a rubber substrate, a first porous cotton layer, a second porous cotton layer, a first foam layer, a second foam layer, a surface board, and a protective film, utilizes the four-layer porous structure of the first porous cotton layer, the second porous cotton layer, the first foam layer, and the second foam layer to convert sound energy into heat energy, thereby greatly reducing the propagation of noise. The surface board, made of high-density PC board, can reflect sound waves, reduce the frequency of noise transmission through the noise-reducing board, and also protect the internal structure of the noise-reducing board. When subjected to noise transmission, the rubber substrate can absorb vibration energy through elastic deformation, thereby weakening the vibration transmission of noise sound waves and further reducing noise. The entire noise-reducing board, through the outer, middle, and inner three-layer sound insulation structure, adopts three methods respectively: reflecting sound waves, absorbing and converting sound waves, and weakening sound wave vibration through elastic deformation, which can fully and efficiently eliminate noise, thereby greatly improving the noise isolation effect and avoiding noise pollution caused by noise transmission.

[0016] 2. This utility model, through the setting of a rear connecting plate, a front connecting plate, sound insulation pads, positioning screw holes, and connecting screw holes, allows the rear connecting plate of one support frame to be connected with the front connecting plate of another support frame. The positioning screw holes and connecting screw holes are aligned, and the two support frames can be assembled by tightening bolts. During assembly, the joints are filled with sound insulation pads. The entire noise reduction board can be spliced ​​and expanded according to the construction range. Moreover, the noise reduction boards adopt an independent splicing mode, so only a single part needs to be replaced when replacing, reducing replacement costs. Furthermore, the use of sound insulation pads to fill the joints can prevent noise from being transmitted through the splicing joints, thus improving the sound insulation effect at the joints.

Detailed Implementation

[0021] 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.

[0022] like Figures 1-3 As shown, a green building construction energy-saving noise reduction board includes a noise reduction board body 1. The noise reduction board body 1 includes a rubber substrate 101 as the base layer of the entire board body. A first porous cotton 102 is fixedly connected to the front side of the surface of the rubber substrate 101, and a second porous cotton 103 is fixedly connected to the rear side of the surface of the rubber substrate 101. A first foam layer 104 is fixedly connected to the front side of the surface of the first porous cotton 102, and a second foam layer 105 is fixedly connected to the rear side of the surface of the second porous cotton 103. A surface layer 106 is fixedly connected to both the front side of the first foam layer 104 and the rear side of the second foam layer 105. A protective film 107 is pasted onto the surface of the surface layer 106.

[0023] By adopting the above technical solution, the first porous cotton 102, the second porous cotton 103, the first foaming layer 104 and the second foaming layer 105 all utilize the pore structure to convert sound energy into heat energy, thereby greatly reducing the propagation of noise.

[0024] The surface plate 106 can reflect sound waves to reduce the frequency of noise transmission through the noise reduction plate 1, and can also protect the internal structure of the noise reduction plate 1.

[0025] When the substrate 101 is subjected to noise transmission, it can absorb vibration energy through elastic deformation, thereby weakening the vibration transmission of noise waves and further reducing noise.

[0026] The protective film 107 can protect the outer surface of the surface plate 106, preventing corrosion damage caused by long-term exposure of the surface plate 106.

[0027] Furthermore, both the first porous cotton 102 and the second porous cotton 103 are made of rock wool, and the first porous cotton 102 and the second porous cotton 103 form a double sandwich structure in the inner layer of the noise reduction board 1; the first foam layer 104 and the second foam layer 105 are made of either PVC foam or polyurethane, and the first foam layer 104 and the second foam layer 105 form a double sandwich structure in the middle layer of the noise reduction board 1.

[0028] By adopting the above technical solution, the first porous cotton 102, the second porous cotton 103, the first foam layer 104 and the second foam layer 105 are integrated into a four-layer structure in the middle layer of the noise reduction board 1, forming a front and rear sandwich state, which can reduce noise on both the front and rear sides.

[0029] Furthermore, the surface panel 106 is made of high-density PC board, and the protective film 107 is made of polypropylene film material.

[0030] By adopting the above technical solution, the PC board is made of high-density material, which enables the surface board 106 to reflect sound waves. The protective film 107 made of polypropylene film has wear-resistant and moisture-proof properties. As a protective film, the protective film 107 can prevent the surface board 106 from being corroded and worn, extend the service life of the surface board 106, and also improve the protective effect of the surface board 106 on the internal structure of the noise reduction board 1.

[0031] Furthermore, the same support frame 2 is fixedly connected to the outer side of the noise reduction plate 1 as a whole. A rear connecting plate 3 is fixedly installed on the rear side of the left surface of the support frame 2, and a front connecting plate 4 is fixedly connected to the front side of the right surface of the support frame 2.

[0032] By adopting the above technical solution, the two noise reduction boards can be horizontally spliced ​​using the rear connecting plate 3 and the front connecting plate 4.

[0033] Furthermore, sound insulation pads 5 are fixedly connected to the surfaces of the rear connecting plate 3 and the front connecting plate 4 on the side near the front and rear center points of the support frame 2, and the thickness of the rear connecting plate 3 and the front connecting plate 4 combined with the sound insulation pads 5 is the same as the thickness of the entire support frame 2.

[0034] By adopting the above technical solution, after the rear connecting plate 3 and the front connecting plate 4 are spliced ​​together, it can be ensured that the two noise reduction plates are on the same plane, thus avoiding uneven installation.

[0035] The seams are filled with sound-insulating pads 5 to prevent noise from being transmitted through the seams.

[0036] Furthermore, a positioning screw hole 6 is provided through the sound insulation pad 5 on the front side of the rear connecting plate 3, and a connecting screw hole 7 is provided through the entire surface of the front connecting plate 4.

[0037] By adopting the above technical solution, the rear connecting plate 3 of one support frame 2 is connected to the front connecting plate 4 of another support frame 2, the positioning screw hole 6 and the connecting screw hole 7 are aligned, and the two support frames 2 can be assembled by fastening with bolts.

[0038] Working Principle: When using this green building construction energy-saving and noise-reducing panel, firstly, depending on the size of the construction site, the rear connecting plate 3 of one support frame 2 is connected to the front connecting plate 4 of another support frame 2, aligning the positioning screw holes 6 and connecting screw holes 7, and then tightening with bolts to assemble the two support frames 2 until the assembly covers the entire construction area. During construction, when noise is transmitted, the four-layer porous structure of the first porous cotton 102, the second porous cotton 103, the first foam layer 104, and the second foam layer 105 converts sound energy into heat energy, thereby greatly reducing noise propagation. The surface panel 106, made of high-density PC board, reflects sound waves, further reducing noise. The low frequency of noise transmission through the noise reduction panel 1 can also protect the internal structure of the noise reduction panel 1. When the rubber substrate 101 is subjected to noise transmission, it can absorb vibration energy through elastic deformation, thereby weakening the vibration transmission of noise waves and further reducing noise. The entire noise reduction panel 1 uses an outer, middle and inner three-layer sound insulation structure, which adopts three methods: reflecting sound waves, absorbing and converting sound waves, and weakening sound wave vibration through elastic deformation, to fully and efficiently eliminate noise. In addition, sound insulation pads 5 are used to fill the joints of each noise reduction panel to prevent noise from being transmitted through the joints and improve the sound insulation effect at the joints. This is the working principle of the energy-saving noise reduction panel for green building construction.
