Description

Technology Field

[0001] The present invention relates to a soundproofing device for preventing inter-floor noise in a building, and more specifically, to a soundproofing device for preventing inter-floor noise in a building that sequentially attenuates and eliminates various impacts, impact sounds, and noise transmitted from the top of the finishing material, thereby preventing any impact or noise from being transmitted between floors. Background Technology

[0003] Generally, when constructing slabs for multi-unit dwellings such as apartments, formwork is installed to ensure a level surface, followed by rebar placement and concrete pouring. On top of this, expanded polystyrene, floor cushioning materials, film, and lightweight foamed concrete are poured, mesh is laid, heating pipes are installed on top, and the surface is finished with cement mortar.

[0004] As such, since the slabs separating floors of multi-story buildings such as apartments and high-rise buildings are constructed solely of concrete, noise and vibrations caused by impact generated within the corresponding floor of the building are transmitted directly to the floor below through the inter-floor slabs.

[0005] Impact sounds applied to the building structures of multi-unit dwellings, such as apartments or villas, are solid-borne sounds generated by impacts caused by human walking, the opening and closing of doors, the movement of objects, or the operation or stopping of equipment. These sounds are transmitted in all directions, causing not only vibrations in the building structure but also to be converted into airborne sound. When this sound reaches the ears of people in the vicinity, it is perceived as noise.

[0006] Especially in buildings constructed nowadays, improving sound insulation is being considered more than improving thermal insulation.

[0007] Traditionally, the goal was to construct buildings with insulation and heat resistance that provide a warm and comfortable environment and reduce costs, such as heating expenses that naturally occur during the summer and winter.

[0008] However, in South Korea, where communal collective living such as apartments has become common, the number of residents suffering from inter-floor noise is increasing, so the full installation of soundproofing facilities is being accepted as an increasingly necessary construction requirement.

[0009] When multiple households maintain a communal or collective life within a single building, each household generates different types of noise. Households with elementary school students, households where the resident is a drummer, and households with very loud and boisterous children generate a higher level of noise compared to other households. Consequently, the upper, lower, or side areas of the floors where these households reside are exposed to loud noise, making it virtually impossible to live comfortably and peacefully.

[0010] The soundproofing member for preventing inter-floor noise in a building according to Registered Patent No. 0816676 (March 19, 2008) is configured such that a plurality of soundproofing panels are stacked, with suction holes formed to communicate with each other on the same vertical line.

[0011] That is, by laminating a soundproofing member with a noise reduction section formed between the floor slab layer and the mortar layer of a building, noise generated from the upper floor can be significantly reduced, and corresponding concave and convex parts are formed on the upper and lower and front, rear, left, and right ends that come into contact with the first, second, and third soundproofing panels of the soundproofing member, respectively, thereby preventing misalignment and separation between the soundproofing panels.

[0012] However, soundproofing structures like those in conventional technology simply stack multiple soundproofing panels to minimize noise, so while sound can be blocked, there is a problem in that sounds generated by impact or collision cannot be blocked. Prior art literature

[0018] Between each of the aforementioned mutually adjacent buffer blocks, assembly protrusions are formed on adjacent sides so as to protrude from the top, and assembly grooves are formed on the other sides so that the assembly protrusions can be assembled downward from the top.

Specific details for implementing the invention

[0024] Below, embodiments of the present invention are described in detail with reference to the attached drawings so that those skilled in the art can easily implement the invention.

[0025] The scope of the present invention shall not be interpreted as being limited by the embodiments described in the text.

[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the description of the embodiments, the same reference numerals are assigned to identical components, and in some cases, the description of the same reference numerals is omitted.

[0027] FIG. 1 is an exploded perspective view illustrating a soundproofing device for preventing inter-floor noise in a building according to the present invention, and FIG. 2 is a combined cross-sectional view illustrating a soundproofing device for preventing inter-floor noise in a building according to the present invention.

[0028] As illustrated, the soundproofing device for preventing inter-floor noise in a building according to the present invention is largely composed of a buffer block (10), a pressure plate (20), a module fixing plate (30), a waterproof layer (40), and an insulating material (50).

[0029] The cushioning block (10) of the present invention is formed in the shape of a cuboid as shown in FIG. 3, and assembly protrusions (11) are formed on adjacent sides so as to protrude from the top, and assembly grooves (12) are formed on the other sides so that the assembly protrusions (11) can be assembled downward from the top.

[0030] Therefore, the buffer blocks (10) are assembled along the upper surface of the concrete slab to ensure uniform ventilation, thereby covering the upper surface of the concrete slab.

[0031] These cushioning blocks (10) are made elastic so that they contract and expand in the vertical direction.

[0032] However, the assembly protrusion (11) and assembly groove (12) formed on the buffer block (10) are not necessarily limited to the shape shown in the drawing.

[0033] A flat pressure plate (20) having the same planar shape and size as the upper surface of each buffer block (10) is provided on the upper surface of the buffer blocks (10) arranged to cover the upper surface of the concrete slab.

[0034] That is, the pressure plate (20) is configured to be a flat plate that covers the upper surface of each buffer block (10) and is configured to ensure that impact applied from above is uniformly applied to the upper surface of the buffer block (10). In the center of the plate surface of the pressure plate (20), a fitting projection (21) is integrally formed downward so as to be fitted into a fitting hole (13) formed to penetrate vertically into the center of the buffer block (10).

[0035] At this time, the fitting hole (13) and the fitting projection (21) are formed with the same shape, but are not limited to the shape shown, and it is most preferable to form them in a polygonal shape so that they cannot rotate relative to the cushioning block (10).

[0036] The pressure plate (20) may be formed of a hard material such as synthetic resin or metal so as to uniformly press the upper surface of the buffer block (10).

[0037] In addition, a module fixing plate (30) is placed on the upper part of each pressure plate (20).

[0038] The module fixing plate (30) of the present invention is a hard plate made of thin sheet metal formed with an outer diameter that is the same planar shape and size as the pressure plate (20) as shown in FIG. 4, and the center is vertically penetrated with a predetermined shape and size.

[0039] The module fixing plate (30) is provided with a gel-shaped dustproof module (31) on the upper and lower surfaces and connected thereto.

[0040] The dustproof module (31) may be fixed by simply being in close contact with the module fixing plate (30), or it may be fixed by being bonded with an adhesive or the like.

[0041] The anti-vibration module (31) acts as a buffer against impact from above and can also reduce noise.

[0042] In particular, the upper part of the upper anti-vibration module (31), which is designed to attenuate vibration and noise by the anti-vibration module (31) of the module fixing plate (30), is covered by a waterproof layer (40).

[0043] A waterproof layer (40) is formed by laying a mesh net (42) on top of a nonwoven fabric (41) applied to cover the upper surface of a module fixing plate (30), and then applying a waterproofing liquid to the top of it to a predetermined thickness so that the waterproofing liquid hardens, thereby forming a waterproof layer (40) with a predetermined thickness while the nonwoven fabric (41) and the mesh net (42) are combined as a single unit.

[0044] Meanwhile, an insulating material (50) is provided on the upper part of the waterproof layer (40) to block heat transfer.

[0045] It is most desirable to form the insulation material (50) with a heat-resistant material.

[0046] As mentioned above, the operation and effects of the soundproofing device for preventing inter-floor noise in a building according to the present invention will be explained in more detail as follows.

[0047] The present invention is configured to be stacked on top of a concrete slab separating the layers, and as shown in FIG. 5, a buffer block (10) is sequentially connected to the concrete slab (S) so that the upper surface of the concrete slab (S) is covered.

[0048] The buffer blocks (10) are arranged uniformly by a continuous assembly process in which assembly protrusions (11) formed on both sides from the top, as shown in FIG. 6, are fitted into the assembly grooves (12) of adjacent buffer blocks (10) on both sides.

[0049] On each upper surface covered by the buffer block (10), a pressure plate (20), a module fixing plate (30), a waterproof layer (40), and an insulating material (50) are sequentially stacked.

[0050] A heating pipe layer is formed on the upper part of the insulation material (50) and then the finishing material is laminated, or the finishing material is laminated directly on the upper part of the insulation material (50).

[0051] With this configuration, when a strong impact or noise is generated on the finishing material from the top of the finishing material, this impact and noise are first transmitted to the waterproof layer (40) through the insulation material (50), and the insulation material (40) and the waterproof layer (40) block heat transfer between layers while simultaneously ensuring waterproofing.

[0052] By forming a module fixing plate (30) at the bottom of the waterproof layer (40), vibrations and noise transmitted through the waterproof layer (40) by the anti-vibration module (31) are attenuated.

[0053] In addition, the pressure plate (20) located at the bottom of the module fixing plate (30) causes the shock and noise that still remain through the module fixing plate (30) to be attenuated again and transmitted to the buffer block (10) provided at the bottom of the pressure plate (20) so that they are completely eliminated.

[0054] Thus, the present invention enables the complete elimination of inter-floor noise and impact by attenuating the impact, impact sound, and noise transmitted through the finishing material over several cycles.

[0055] As such, it is obvious to those skilled in the art that the present invention is not limited to the described embodiments and can be modified and varied in various ways without departing from the spirit and scope of the invention. Accordingly, such modifications or variations should be deemed to fall within the scope of the claims of the present invention. Explanation of the symbols
