Technical Field
[0001] The present application belongs to the technical field of building noise prevention, and more specifically, relates to an L-shaped noise prevention structure. Background Art
[0002] At present, there are generally three types of noise prevention measures for building downpipes: the first is to enclose the downpipes with brick masonry and the building's inner corner walls. This method has high costs, long construction periods, and occupies a large area, and is not suitable for modern prefabricated and dry construction requirements; the second is to assemble lightweight wall panels and enclose the downpipes with the building's inner corner walls. Although this method meets the requirements of modern prefabricated and dry construction, it still has problems of high costs, long construction periods, and large occupied areas; the third is to use L-shaped thin-walled components and the building's inner corner walls to enclose the downpipes. This method solves the above-mentioned shortcomings, but the sound insulation effect is poor, the L-shaped thin-walled structure has low strength, and its side edges are fixed to the wall with metal clips, which has poor durability and stability.

[0004] To achieve the above-mentioned purpose, the technical solution adopted in the embodiment of the present application is: to provide an L-shaped noise-proof structure, which is arranged at the dark corner of the downpipe in the room and enclosed outside the downpipe, including a first flat plate and a second flat plate perpendicular to each other, the first flat plate and / or the second flat plate including a noise-reducing inner layer and a reinforced outer layer, the noise-reducing inner layer is formed by lightweight material, the reinforced outer layer is formed by solidifying slurry, a hollow structure and / or a concave hole structure is provided in the noise-reducing inner layer, the hollow structure and / or the concave hole structure are filled with the slurry of the reinforced outer layer, and the side edges of the first flat plate and the second flat plate are sealed and fixed to the building wall or air duct.
[0005] Specifically, the cross-sectional shape of the through-hole structure and / or the concave hole structure is a strip shape, a circle or an irregular shape.

[0008] Specifically, the outer surface of the reinforced outer layer is a convex-concave surface.
[0009] Specifically, the side edges of the first flat plate and the second flat plate are provided with vertical notches opening outward. When the L-shaped noise-proofing structure is installed, the vertical notches and the building wall or air duct are enclosed to form a vertical gap opening outward. By filling the vertical gap with sealing material, the L-shaped noise-proofing structure is sealed and fixed to the building wall or air duct.
[0010] Specifically, an inspection port is provided on the first flat plate or the second flat plate.
[0011] Specifically, the noise reduction inner layer is a single-layer hollow plate; or, the noise reduction inner layer is formed by overlapping multiple layers of hollow plates.

[0035] Example 1
[0036] See Figure 1 、 Figure 2 As shown, an L-shaped noise-proofing structure 40 provided in the first embodiment of the present application is arranged at the inner corner of the downpipe 10 in the room, supported on the floor 20 and enclosed with the building wall 30 to form a rectangular space, and the downpipe 10 is located in the rectangular space. The L-shaped noise-proofing structure 40 includes a first flat plate 41 and a second flat plate 42 perpendicular to each other. The first flat plate 41 and / or the second flat plate 42 include a noise-reducing inner layer 43 and a reinforcing outer layer 44. The noise-reducing inner layer 43 is formed from a lightweight material, and the reinforcing outer layer 44 is formed by curing slurry. A hollow structure 45 is provided in the noise-reducing inner layer 43, and the hollow structure 45 is filled with the slurry of the reinforcing outer layer 44. When the L-shaped noise-proofing structure 40 is installed at the inner corner of the downpipe 10, the side edges of the first flat plate 41 and the second flat plate 42 are sealed and fixed to the building wall 30.
[0037] In the present application, the L-shaped noise-proofing structure 40 is used for noise reduction treatment of the building downpipe 10. It is arranged on the outside of the building downpipe 10 and wraps the building downpipe 10 inside. Since the inner side of the L-shaped noise-proofing structure 40 is provided with a noise-reducing inner layer 43, it can effectively reduce the impact of falling water noise on the indoor environment; at the same time, the noise-reducing inner layer 43 is provided with a hollow structure 45, and the slurry of the reinforced outer layer 44 fills the hollow structure 45, thereby strengthening the connection between the noise-reducing inner layer 43 and the reinforced outer layer 44, effectively preventing the separation between the inner and outer layers, and improving the impact resistance and pressure resistance of the L-shaped noise-proofing structure 40, preventing the L-shaped noise-proofing structure 40 from breaking, and improving the mechanical properties of the L-shaped noise-proofing structure 40.
[0038] Specifically, the cross-sectional shape of the hollow structure 45 is a strip shape, a circle shape or an irregular shape.
[0039] Specifically, the outer reinforcement layer 44 is formed by solidifying cement mortar, and the internal reinforcement 46 is a metal mesh to enhance the crack resistance and impact resistance of the L-shaped noise-proof structure 40. Of course, the reinforcement 46 can also be replaced by steel bars, steel wire, metal short wire, short fibers, fiber bundles, fiber mesh, etc.
[0040] In this embodiment, the noise-reducing inner layer 43 is an extruded board. This board is lightweight and has a certain strength, which facilitates the formation of the L-shaped noise-reducing structure 40 and helps improve the strength of the L-shaped noise-reducing structure 40. Of course, the noise-reducing inner layer 43 can also be replaced by other sound-absorbing board materials such as lightweight polystyrene board, polyurethane board, damping board, sound insulation cotton, mineral wool board, fiber tow, ceramsite, sponge board, bubble board, foam glue or foaming agent molding.
[0041] Reference Figure 1 In this embodiment, the side edges of the first plate 41 and the second plate 42 are provided with vertical notches 47 opening outwards. Figure 2 During installation, the L-shaped noise-proofing structure 40's vertical notch 47 encloses the building wall 30, forming an outward-facing vertical gap 48. Filling the vertical gap 48 with sealing slurry 50 secures the L-shaped noise-proofing structure 40 to the building wall 30, effectively ensuring the stability of the decorative surface, such as the veneer tiles, on the L-shaped noise-proofing structure 40 without cracking or hollowing, and forming a secure, stable, closed rectangular space outside the downpipe 10. In this embodiment, the cross-sectional shape of the vertical gap 48 is polygonal. This shape enhances the adhesion between the side edges of the first and second flat plates 41, 42 and the building wall 30.
[0042] In this embodiment, the noise reduction inner layer 43 and the reinforcement outer layer 44 are integrally formed. Of course, they can also be spliced, bound, or bonded.
[0043] In this embodiment, the noise reduction inner layer 43 is a single-layer extruded board. Of course, the noise reduction inner layer 43 can be a single-layer hollow board, or the noise reduction inner layer can also be composed of multiple layers of hollow boards stacked together.
[0044] In this embodiment, the left and right sides and / or upper and lower ends of the first plate 41 and the second plate 42 are formed by solidifying slurry. The L-shaped noise-proofing structure 40 is surrounded by solidifying slurry to enhance its anti-bending strength.
[0045] Example 2
[0046] See Figure 3 , Figure 4 As shown, in the L-shaped noise-proof structure 40 provided in the second embodiment of the present application, the cross-section of the vertical gap 48 formed by the vertical notch 47 at the side edge of the first plate 41 and the second plate 42 and the building wall 30 is triangular. This shape makes it easier to shape the side edges of the first plate 41 and the second plate 42.
[0047] Moreover, in this embodiment, the L-shaped noise-proof structure 40 is supported on the waterproof sill 60 , and the L-shaped noise-proof structure 40 and the building wall 30 not only enclose the downpipe 10 but also the water supply pipe 70 .
[0048] In this embodiment, an inspection port 49 is provided on the L-shaped noise-proof structure 40, and a sealing device (not numbered in the figure) is provided on the inspection port 49. By providing the inspection port 49, the sealing device can be opened to facilitate maintenance of the internal downpipe 10.
[0049] In this embodiment, there is no floor 20 in the rectangular space enclosed by the L-shaped noise-proof structure 40 and the building wall 30 , that is, the rectangular space enclosed by the L-shaped noise-proof structure 40 and the building wall 30 is continuous from top to bottom.
[0050] In this embodiment, other structures of the L-shaped noise-proof structure 40 are the same as those in the first embodiment and will not be described again here.
[0051] Example 3
[0052] Reference Figure 5 、 Figure 6 In the L-shaped noise-proofing structure 40 provided in the third embodiment of the present application, the cross-section of the vertical gap 48 formed by the vertical notches 47 on the side edges of the first and second panels 41, 42 and the building wall 30 differs from that in the first and second embodiments. In this embodiment, the cross-section has an arcuate edge and a segmented, outward-opening vertical gap 48. This allows for secure installation of the L-shaped noise-proofing structure 40 while saving on sealing slurry 50. In this embodiment, one of the first and second panels 41, 42 is sealed and fixed to the building wall 30, while the other is sealed and fixed to the air duct 80.
[0053] In this embodiment, the noise reduction inner layer 43 is provided with a recessed hole structure 410. Compared to the open hole structure 45, the recessed hole structure 410 does not penetrate the noise reduction inner layer 43. The slurry of the reinforcing outer layer 44 fills the recessed hole structure 410, which also strengthens the connection between the noise reduction inner layer 43 and the reinforcing outer layer 44. The recessed hole structure 410 also facilitates demolding during the manufacture of the L-shaped noise-proofing structure 40.
[0054] In this embodiment, the outer surface of the reinforced outer layer 44 of the first flat plate 41 and the second flat plate 42 is a convex-concave surface 411. The convex-concave surface 411 has better pulling force, so that the decorative veneer is better bonded to the convex-concave surface 411.
[0055] In this embodiment, the reinforcements 46 of the outer layer 44 are exposed on the left and right sides of the first and second plates 41, 42. This exposed reinforcement 46, combined with the filler slurry in the vertical gaps 48, provides a stronger tensile strength, ensuring a more secure installation between the L-shaped noise-damping structure 40 and the building wall or air duct.
[0056] In this embodiment, other structures of the L-shaped noise-proof structure 40 are the same as those in the first embodiment and will not be described again here.
[0057] The above is only a specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed in this application, which should be covered by the scope of protection of the present application.
