Description

Technical Field

[0001] This application relates to the field of double-layer curtain wall noise reduction technology, specifically a building sound insulation and noise reduction device with a double-layer curtain wall structure. Background Technology

[0002] With the acceleration of urbanization and the increase in building density, especially in commercial areas, busy transportation hubs and industrial areas, noise affects the working environment inside buildings and the quality of life of residents. In order to effectively reduce the interference of external noise on the interior space of buildings, double-glazed curtain wall structures are commonly used in building design. Double-glazed curtain walls can not only improve the aesthetics and transparency of the building facade, but also provide sound insulation and energy efficiency improvement to a certain extent.

[0003] Currently, during the installation of double-glazed curtain walls, the gap between the two panes of glass is typically sealed with simple sealant. This relies on the air gap between the glass panes to achieve a certain level of sound insulation and noise reduction. Double-glazed curtain walls, with their two panes of glass and hollow structure, can effectively reduce the transmission of external noise, especially in the isolation of mid-to-high frequency noise. However, the sound insulation and noise reduction effects of existing double-glazed curtain wall technologies have certain limitations. Since most double-glazed curtain wall structures rely solely on sealant for sealing, and the sealant has a limited lifespan, the sealing performance of the curtain wall is greatly reduced as the sealant ages. This leads to increased air infiltration and noise transmission, directly affecting the sound insulation effect.

[0004] Therefore, this application provides a building sound insulation and noise reduction device with a double-layer curtain wall structure to solve the above problems. Utility Model Content

[0005] This application provides a building sound insulation and noise reduction device with a double-layer curtain wall structure, which aims to solve the problem mentioned in the background art that when the sealant ages, the sealing performance of the curtain wall is greatly reduced, leading to increased air infiltration and noise transmission, thereby directly affecting the sound insulation effect.

[0006] To achieve the above objectives, this application provides the following technical solution: a building sound insulation and noise reduction device with a double-layer curtain wall structure, comprising a first prefabricated steel structure component and a second prefabricated steel structure component fixedly installed on the first prefabricated steel structure component, wherein a fixing seat is fixedly installed between the first prefabricated steel structure component and the second prefabricated steel structure component, and a double-layer glass curtain wall is provided on each fixing seat;

[0007] The exterior of the double-glazed curtain wall is equipped with a noise reduction mechanism;

[0008] The noise reduction mechanism includes an assembly base installed on the side of the double-glazed curtain wall and a positioning plate opposite to it. Each end of the positioning plate has a connecting seat, and two assembly rails are equidistantly arranged on the inner wall of the positioning plate. A limit block is fixedly installed at the end of the positioning plate away from the assembly rails. Sealing strips are symmetrically arranged on the positioning plate, and two sound insulation plates are equidistantly arranged between the two sealing strips. The assembly base has an assembly slot for inserting the double-glazed curtain wall. The noise reduction mechanism is integrated with the curtain wall design, making installation more convenient and providing better sealing compared to traditional external sound insulation devices or sealant sealing.

[0009] Preferably, the upper sealing strip is bonded to the upper end of the outermost mounting rail, and several fixing posts are installed at equal intervals between the two mounting rails. The lower sealing strip is bonded to the lower end of the limiting block to form upper and lower sealing boundaries to prevent sound from leaking out from the edge of the noise reduction mechanism.

[0010] Preferably, the two sound insulation panels are respectively inserted into two mounting rails, and an air isolation layer is formed between the two sound insulation panels. The air isolation layer can be filled with argon gas, thereby further improving the noise reduction effect.

[0011] Preferably, a sound-insulating cotton is provided between the lower sealing strip and the sound insulation board, and the lower end of the sound-insulating cotton has a groove that matches the limiting block. The sound-insulating cotton and the limiting block are fixed by sealant.

[0012] Preferably, a first rubber pad is fixedly installed on the side of the second precast steel structure near the double-glazed curtain wall, and a second rubber pad corresponding to the first rubber pad is fixedly installed on the fixing seat.

[0013] This noise reduction device provides noise reduction during the assembly of double-glazed curtain walls by setting noise reduction mechanisms on the sides of the double-glazed curtain wall. The positioning plate is installed on the assembly base through the connecting seat, and the sealing strip and the sound insulation plate form a multi-layer sound insulation barrier to block the transmission of sound. Two sound insulation plates are inserted into the assembly rail to form a small-sized air isolation layer, which is filled with argon gas to further improve the noise reduction effect.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] This embodiment provides a building sound insulation and noise reduction device with a double-layer curtain wall structure, such as Figure 1-6 As shown, the noise reduction device includes a first prefabricated steel structure 1 that is relatively distributed and a second prefabricated steel structure 2 that is fixedly installed on the first prefabricated steel structure 1. A fixing seat 22 is fixedly installed between the first prefabricated steel structure 1 and the second prefabricated steel structure 2, and a double-layer glass curtain wall 3 is provided on each fixing seat 22.

[0024] The exterior of the double-glazed curtain wall 3 is equipped with a noise reduction mechanism 4;

[0025] The noise reduction mechanism 4 includes an assembly base 41 installed on the side of the double-glazed curtain wall 3 and a positioning plate 43 oppositely arranged on the assembly base 41. Both ends of the positioning plate 43 are provided with connecting seats 44. Two assembly rails 48 are equidistantly arranged on the inner wall of the positioning plate 43. A limit block 49 is fixedly installed on the end of the positioning plate 43 away from the assembly rails 48. Sealing strips 45 are symmetrically arranged on the positioning plate 43. Two sound insulation plates 46 are equidistantly arranged between the two sealing strips 45. The assembly base 41 is provided with an assembly groove 42 for inserting the double-glazed curtain wall 3.

[0026] Specifically, the first precast steel structure component 1 and the second precast steel structure component 2 form a rigid support through the fixing seat 22, fixing the double-layer glass curtain wall 3. The mounting seat 41 of the noise reduction mechanism 4 is fixed on the side of the double-layer glass curtain wall 3, which provides noise reduction for the assembly of double-layer glass. The positioning plate 43 is installed on the mounting seat 41 through the connecting seat 44. The sealing strip 45 and the sound insulation plate 46 form a multi-layer sound insulation barrier to block the sound transmission. The mounting rail seat 48 is used to position the sound insulation plate 46. The limiting block 49 restricts the displacement of the sound insulation plate 46. The sound insulation plate 46 is a high-density fiber cement board with a rectangular strip shape. The mounting rail seat 48 is made of aluminum alloy with a U-shaped cross section, which is fitted with the sound insulation plate 46 with appropriate gap. The sealing device is located inside the double-layer glass, which effectively reduces the impact of external factors on the service life.

[0027] The upper sealing strip 45 is bonded to the upper end of the outermost assembly rail seat 48, and several fixing posts 481 are installed at equal intervals between the two assembly rail seats 48. The lower sealing strip 45 is bonded to the lower end of the limiting block 49.

[0028] More specifically, the upper sealing strip 45 is bonded to the upper end of the mounting rail seat 48, and the lower sealing strip 45 is bonded to the lower end of the limiting block 49, forming upper and lower sealing boundaries to prevent sound from leaking out from the edge of the noise reduction mechanism 4. The sealing strip 45 is made of EPDM rubber with a Shore hardness of A70 to ensure sealing reliability. The sealing strip 45 is bonded with silicone sealant to enhance sealing performance.

[0029] Two sound insulation panels 46 are respectively inserted into two mounting rails 48, and an air isolation layer is formed between the two sound insulation panels 46.

[0030] Furthermore, two sound insulation panels 46 are inserted into the mounting rail 48 to form a small-sized air isolation layer. Argon gas is filled in this isolation layer, and the low acoustic impedance characteristics of air are used to create a sudden change in acoustic impedance with the high density of the sound insulation panels 46.

[0031] A sound insulation cotton 47 is provided between the lower sealing strip 45 and the sound insulation plate 46. The lower end of the sound insulation cotton 47 has a groove that matches the limiting block 49. The sound insulation cotton 47 and the limiting block 49 are fixed with sealant.

[0032] It should be noted that the sound insulation cotton 47 is filled between the sealing strip 45 and the sound insulation board 46 to absorb and reflect sound waves and reduce sound energy. The groove and the limiting block 49 cooperate and are fixed by sealant to prevent the sound insulation cotton 47 from shifting. The sound insulation cotton 47 is made of centrifugal glass wool.

[0033] A first rubber pad 21 is fixedly installed on the side of the second precast steel structure component 2 near the double-glazed curtain wall 3, and a second rubber pad 23 corresponding to the first rubber pad 21 is fixedly installed on the fixing seat 22.

[0034] It is worth mentioning that the first rubber pad 21 and the second rubber pad 23 are respectively installed on the second prefabricated steel structure component 2 and the fixed seat 22 to form elastic support and block the solid sound transmission path.

[0035] In use, the mounting base 41 of the noise reduction mechanism 4 is fixed to the side of the double-glazed curtain wall 3. It provides noise reduction for the assembly of double-glazed glass. The positioning plate 43 is installed on the mounting base 41 through the connecting base 44. The sealing strip 45 and the sound insulation plate 46 form a multi-layer sound insulation barrier to block the transmission of sound. The two sound insulation plates 46 are inserted into the mounting rail 48 to form a small-sized air isolation layer. Argon gas is filled in the isolation layer to further improve the noise reduction effect.
