Description

Technical Field

[0001] This invention relates to the field of building decoration technology, specifically to a design structure for a high-efficiency sound insulation and heat preservation wall for large conference spaces. Background Technology

[0002] To meet the demands of social development, more and more hotels, guesthouses, and conference centers are seeking diversified operations and cannot rely on overly singular uses. This has led to a surge in urban renewal and redevelopment projects. Transforming underutilized banquet halls into more efficient conference spaces is a key technical challenge in urban renewal and redevelopment projects, requiring solutions to the following main issues: Large banquet halls are typically spacious with high ceilings and often feature hard materials in their interior design. If converted into meeting spaces, poor sound insulation can cause speakers' voices to be heard outside, leading to issues such as leaked meeting content and noise pollution in the surrounding environment. Furthermore, banquet halls in large, high-end hotels may be located near busy roads or parking lots, where the original soundproofing may only meet the needs of typical banquets. When converted into meeting rooms, noise from vehicles and other crowds can easily enter and disrupt the meeting.

[0003] In response, existing meeting space walls mostly employ sound insulation and heat preservation designs. The sound insulation structure generally uses multi-layered sound-absorbing panels with spacing between them. Each sound-absorbing panel is limited by a support structure to maintain the gap between the panels and ensure sound insulation performance. However, the contact area between the support structure and the panel is limited, and multiple supports can easily lead to damage to the sound-absorbing panels, affecting their performance. The design of multi-layered sound-absorbing panels results in a single sound absorption method and limited sound insulation effect. The stacking of sound-absorbing panels also significantly increases the wall thickness, raises costs, and limits application scenarios. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency sound insulation and heat preservation wall design structure for large conference spaces, in order to solve the problems of existing soundproof walls having a single sound absorption method, limited sound insulation effect, and easy damage to the internal structure affecting their performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency sound insulation and heat preservation wall design structure for large conference spaces, comprising: The first wall panel has a first sound-absorbing plate, a second sound-absorbing plate, and a third sound-absorbing plate arranged sequentially from the outside to the inside in its inner cavity. There are gaps between the second sound-absorbing plate and the first and third sound-absorbing plates. The first sound-absorbing plate is provided with a number of first sound-absorbing holes, the second sound-absorbing plate is provided with a number of second sound-absorbing holes, and the surface of the third sound-absorbing plate is provided with a number of sound-absorbing blocks. The second wall panel is encapsulated at the opening of the first wall panel. An insulation layer is provided on its inner end face. Several abutment seats are provided on the inner side of the insulation layer. Each abutment seat includes a base, an elastic sound-absorbing disc, and a connector provided between the base and the elastic sound-absorbing disc. The elastic sound-absorbing disc is punctured to form several sound-absorbing microholes. When the second wall panel is assembled on the first wall panel, the elastic sound-absorbing disc abuts against the first sound-absorbing plate, the connector is deformed by pressure and expands the elastic sound-absorbing disc, and a plurality of sound-absorbing micro-holes open and correspond to the first sound-absorbing hole.

[0006] As a further description of the above technical solution: The diameters of the silencing micropores, the first silencing hole, and the second silencing hole increase sequentially.

[0007] As a further description of the above technical solution: The sound-absorbing block is a sound-absorbing wedge, which includes at least one of glass wool, rock wool, slag wool, polyester fiber, and polyurethane foam material.

[0008] As a further description of the above technical solution: Several support members are provided between the first silencing plate and the second silencing plate, and between the second silencing plate and the third silencing plate.

[0009] As a further description of the above technical solution: A positioning plate is provided at the end of the support member, and several diagonal braces are provided between the side of the support member and the end face of the positioning plate.

[0010] As a further description of the above technical solution: The second wall panel abuts against the edge of the U-shaped first wall panel or is embedded in the first wall panel, and the mounting plate abuts against or is embedded in the joint between the first wall panel and the second wall panel and is fixed by fasteners.

[0011] As a further description of the above technical solution: The insulation layer is a rock wool board or a glass wool board.

[0012] As a further description of the above technical solution: Several of the bases press the insulation layer onto the second wall panel and secure it with anchor bolts.

[0013] As a further description of the above technical solution: The elastic sound-absorbing disc is at least one of polyurethane foam, EVA foam, damping silicone, EPDM rubber, and butyl rubber.

[0014] As a further description of the above technical solution: The connector is an arc-shaped rod, and several of them are arranged radially and at intervals along the circumference of the base and the elastic sound-absorbing plate.

[0015] In summary, due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art: The soundproof and heat-insulating wall of this invention is based on multi-layer sound-absorbing panels, which absorb noise over a wide frequency range and achieve efficient sound insulation and noise reduction. During assembly with the second wall panel, the connectors undergo elastic bending under pressure, resulting in relative displacement at both ends. This radially expands the elastic sound-absorbing discs, improving upon the conventional multi-point support of the sound-absorbing panels to a multi-disc support docking, reducing the pressure on the sound-absorbing panels and the resulting damage, ensuring stable performance. Simultaneously, the sound-absorbing micropores on the elastic sound-absorbing discs open, forming a four-stage sound-absorbing design with the other three sound-absorbing panels. These micropores possess multiple sound-absorbing functions, including local resonance locking of low-frequency noise and absorption of broadband noise by the porous elastic structure, thereby improving the sound insulation and noise reduction effect. The main sound waves pass sequentially through the micropores, the first sound-absorbing hole, and the second sound-absorbing hole, with the aperture gradually increasing, enabling precise absorption of the main noise reduction target in the meeting space—mid-to-high frequency noise—improving the sound insulation and noise reduction performance in this scenario. The insulation layer provides the wall with stable thermal insulation performance. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example 1:

[0026] Please see Figure 1-3 This invention provides a technical solution: a high-efficiency sound insulation and heat preservation wall design structure for large conference spaces, comprising: The first wall panel 1 has a cavity 2 in which a first sound-absorbing plate 3, a second sound-absorbing plate 4, and a third sound-absorbing plate 5 are arranged sequentially from the outside to the inside (i.e., from the side closer to the meeting space to the side farther away from the meeting space). There are gaps between the second sound-absorbing plate 4 and the first sound-absorbing plate 3 and the third sound-absorbing plate 5. These gaps, together with the holes on each plate, form multiple Helmholtz resonant cavities. The first sound-absorbing plate 3 is provided with a number of first sound-absorbing holes 6, the second sound-absorbing plate 4 is provided with a number of second sound-absorbing holes 7, and the surface of the third sound-absorbing plate 5 is provided with a number of sound-absorbing blocks 8. The second wall panel 9 is encapsulated at the opening of the first wall panel 1. An insulation layer 10 is provided on its inner end face. Several abutment seats 11 are provided on the inner side of the insulation layer 10. Each abutment seat 11 includes a base 12, an elastic sound-absorbing disc 13, and a connector 14 provided between the base 12 and the elastic sound-absorbing disc 13. The elastic sound-absorbing disc 13 is punctured to form several sound-absorbing microholes 15.

[0027] Specifically, both the first sound-absorbing plate 3 and the second sound-absorbing plate 4 are perforated aluminum alloy plates.

[0028] The silencing block 8 is a sound-absorbing wedge, which includes at least one of glass wool, rock wool, slag wool, polyester fiber, and polyurethane foam material. The wedge is 100-200mm long and is located at the deepest part of the inner cavity 2. It is used to absorb the low-frequency noise remaining after the first three stages of silencing. Its surface is coated with a fireproof hard coating.

[0029] The insulation layer 10 is a rock wool board or glass wool board with a thickness of 50-100mm. Several bases 12 press the insulation layer 10 onto the second wall panel 9 and fix it with anchor bolts. The side of the insulation layer 10 closest to the first sound-absorbing board 3 is laminated with a layer of non-woven fabric to prevent fiber shedding.

[0030] The connector 14 is an arc-shaped rod, and several of them are arranged radially and at intervals along the circumference of the base 12 and the elastic sound-absorbing plate 13.

[0031] The elastic sound-absorbing plate 13 is at least one of polyurethane foam, EVA foam, damping silicone, EPDM rubber, and butyl rubber, with a thickness of 5-15 mm. Its surface is formed with multiple sound-absorbing micropores 15 by needle punching or perforation. In the unpressurized state, the sound-absorbing micropores 15 are in a closed or semi-closed state.

[0032] The assembly method of the second wall panel 9 and the first wall panel 1 is as follows: the edge of the second wall panel 9 is embedded in the groove of the first wall panel 1, or as follows: Figure 1 As shown, the second wall panel 9 abuts against the edge of the first wall panel 1 and covers the joint with the mounting plate 19. The mounting plate 19 simultaneously fixes the first wall panel 1 and the second wall panel 9 with fasteners 20 (such as self-tapping screws or expansion bolts).

[0033] The assembly process of a high-efficiency soundproof and heat-insulating wall design structure for a large conference space according to this embodiment includes: when the second wall panel 9 is assembled in place, the outer end face of the elastic sound-absorbing disk 13 abuts against the first sound-absorbing plate 3. As the fastener 20 is tightened, the connecting piece 14 (arc-shaped rod) is compressed and undergoes elastic bending, and its two ends generate relative displacement, thereby opening the elastic sound-absorbing disk 13 radially. After opening, the originally closed sound-absorbing micro-holes 15 are stretched into open through holes, and these sound-absorbing micro-holes 15 correspond to the first sound-absorbing holes 6 on the first sound-absorbing plate 3.

[0034] This soundproof and heat-insulating wall is based on multi-layer sound-absorbing panels, achieving absorption of noise over a wide frequency range and realizing highly efficient sound insulation and noise reduction. The insulation layer provides the wall with stable thermal insulation performance. During the assembly of the second wall panel, the connectors undergo elastic bending under pressure, resulting in relative displacement at both ends. This radially expands the elastic sound-absorbing discs, improving upon the conventional multi-point support of the sound-absorbing panels to a multi-disc support joint, reducing the pressure on the sound-absorbing panels and the resulting damage, ensuring stable performance. Simultaneously, the sound-absorbing micropores on the elastic sound-absorbing discs open, forming a four-stage sound-absorbing design with the other three sound-absorbing panels. The sound-absorbing micropores possess multiple sound-absorbing functions, including local resonance locking of low-frequency noise and porous elastic structure absorption of broadband noise, thereby improving the sound insulation and noise reduction effect, as detailed below: Local resonance locks in low-frequency noise: Through careful design, the entire elastic disk structure becomes a "local resonant unit". When a sound wave of a specific frequency strikes, the elastic disk vibrates strongly, and the scattered sound waves cancel each other out with the incident sound waves, achieving sound insulation and noise reduction.

[0035] Porous elastic structures absorb broadband noise: They utilize elastic materials with countless tiny, interconnected pores within their structure. When sound waves enter, they are repeatedly refracted and rubbed within the labyrinthine pores. The sound energy is efficiently converted into heat energy and dissipated through "viscous heat loss," thus achieving noise reduction.

[0036] Tests showed that the wall structure achieved an average sound absorption coefficient of over 0.85 in the 125Hz-4kHz range, with sound insulation 8-12dB higher than that of ordinary double-layer wall panels. At the same time, the wall's heat transfer coefficient was reduced to below 0.45W / (m²·K), meeting the acoustic and energy-saving requirements of large conference spaces. Example 2:

[0037] Please see Figure 2 , 3The figure shows a high-efficiency sound insulation and heat preservation wall design structure for a large conference space provided by Embodiment 2 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solution: the apertures of the sound-absorbing micro-holes 15, the first sound-absorbing hole 6, and the second sound-absorbing hole 7 are sequentially increased. In this embodiment, the aperture of the sound-absorbing micro-hole 15 is 0.5-1.5 mm, the aperture of the first sound-absorbing hole 6 is 3-8 mm, and the aperture of the second sound-absorbing hole 7 is 10-20 mm. That is, the apertures of the three holes increase sequentially, so that when sound waves move, they pass through the sound-absorbing micro-holes 15, the first sound-absorbing hole 6, and the second sound-absorbing hole 7 in sequence, with the apertures increasing from small to large, accurately absorbing mid-to-high frequency noise (the main target for noise reduction in conference spaces). Specifically, utilizing the Helmholtz resonance principle, the first layer of sound impacts the small aperture with high acoustic impedance, accurately absorbing the target mid-to-high frequencies; the unabsorbed sound energy then enters the large aperture low-frequency resonant cavity for secondary absorption, maximizing the effect. Example 3:

[0038] Please see Figure 3 The figure shows a design structure for a high-efficiency soundproof and heat-insulating wall in a large conference space provided by Embodiment 3 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solutions: To precisely maintain the gap width, several support members 16 are provided between the first sound-absorbing plate 3 and the second sound-absorbing plate 4, and between the second sound-absorbing plate 4 and the third sound-absorbing plate 5. Positioning discs 17 are provided at the ends of the support members 16, and the positioning discs 17 are connected to the surface of the sound-absorbing plates by adhesive bonding or snap-fit. Several diagonal braces 18 are welded or integrally formed between the side of the support member 16 and the end face of the positioning disc 17. This ensures the stable spacing of each sound-absorbing plate, and the above structure forms a triangular stable structure, preventing the support members from bending and further improving the support positioning strength.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
