Description

Technology Field

[0001] The present invention relates to a soundproofing device for inter-floor noise in a building, and more specifically, to a soundproofing device for inter-floor noise in a building having a sound insulation structure that allows the inter-floor wall and slab to be separated vertically at a predetermined height, while simultaneously cushioning vibrations and shocks at the separated ends and blocking noise. 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] In the inter-floor soundproofing structure of a multi-unit dwelling registered patent No. 1953900 (February 25, 2019), a shock-absorbing layer consisting of grid-like holes is formed in the pipe layer formed on the upper part of the slab layer, a noise removal layer is formed in the shock-absorbing layer, and a sound-absorbing layer is disposed between the slab layer and the pipe layer, and the lower and upper surfaces of the sound-absorbing layer are each formed to form a first contact surface and a second contact surface such that ridges and crests in a wave shape intersect each other along the upper and lower paths.

[0011] In other words, it allows noise generated inside each unit to be expelled to the outside, while absorbing noise generated by the pipes used for indoor floor heating and providing sound waves capable of canceling out the noise.

[0012] However, in soundproof structures like those in conventional technology, a layered structure such as a shock-absorbing layer and a noise-removing layer is formed not only on the outside of the heating pipe but also on the top thereof, so while the soundproofing effect is increased, there is a problem of reducing heating efficiency.

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 a side cross-sectional view illustrating an inter-floor noise blocking device for a building according to the present invention.

[0028] As illustrated, the present invention comprises a fixed shaft (10), a resonant pipe (20), a cushioning pad (30), a urethane foam layer (40), a concrete finishing layer (50), and a finishing material (60).

[0029] The fixed shaft (10) of the present invention is a vertical configuration that is fixed so that a certain height of the lower part is embedded in the upper part of the interlayer slab (S) as shown in FIG. 2, while a predetermined height protrudes upward.

[0030] The fixed shafts (10) are formed at uniform intervals in the horizontal and vertical directions on the slab (S).

[0031] However, the fixed shaft (10) must be formed at the location where the side wall (W) is formed on the upper part of the slab (S).

[0032] At this time, an axle sleeve (11) is provided at the upper part of the fixed shaft (10) so as to be able to move up and down to a predetermined height.

[0033] Resonance pipes (20) are provided on the upper part of the slab (S) at uniform intervals along the same horizontal line.

[0034] The resonant pipe (20) is configured to form a space with a predetermined diameter inside as shown in Fig. 3, so as to be disposed in one direction from the upper part of the slab (S).

[0035] A cushioning pad (30) is provided between the resonance pipes (20) spaced at uniform intervals, and surrounds the upper and lower outer surfaces of each resonance pipe (20).

[0036] The cushioning pad (30) is configured such that two or more elastic pads are stacked, and the cushioning pad (30) alternately wraps the upper and lower outer surfaces of the resonant pipe (20) to attenuate vibrations and noise transmitted from the upper and lower parts.

[0037] Each pad of the cushioning pad (30) may simply be in close contact with one another, but may also be fixedly bonded by an adhesive between the pads, and the resonance pipes (20) may also be bonded to these cushioning pads (30) by the adhesive.

[0038] These cushioning pads (30) are formed from at least one of elastic rubber, silicone, or non-woven fabric, and each pad may be formed from the same material or different materials.

[0039] A urethane foam layer (40) of a predetermined thickness is provided in the combination of resonant pipes (20) and cushioning pads (30) from the top and bottom.

[0040] It is preferable that the urethane foam layer (40) be covered up to the upper and lower parts rather than the height of the cushioning pad (30) as shown in FIG. 4, and the lower side urethane foam layer (40) be in close contact with the upper surface of the floor slab (S), and the upper side urethane foam layer (40) also be flattened.

[0041] The urethane foam layer (40) is formed of a rigid polyurethane foam, but is not limited thereto and may be formed of other synthetic resin foams.

[0042] An axle sleeve (11) connected to the upper end of a fixed shaft (10) is formed protruding from the upper side of the urethane foam layer (40), and a concrete finishing layer (50) is formed at a predetermined height on the upper side of the urethane foam layer (40), including the axle sleeve (11).

[0043] That is, when concrete is poured to a predetermined thickness into the upper urethane foam layer (40) and hardened, the shaft sleeve (11), which is provided to protrude above the urethane foam layer (40), becomes embedded in the concrete and hardens, thereby forming a concrete finishing layer (50).

[0044] On the upper part of the concrete finishing layer (50), a side wall (W) is constructed along the formation location of the side wall (W), and a heating pipe layer is formed on the upper part of the concrete finishing layer (50) between the side walls (W), and then finished with a finishing material (60), or the heating pipe layer is omitted and finished directly with a finishing material (60).

[0045] However, it is more preferable to attach a non-woven fabric soaked in a waterproofing liquid to the bottom surface of the finishing material (60) so as to cushion contact collision with the concrete finishing layer (50) or the heating pipe layer while providing waterproofing.

[0046] Meanwhile, it is most desirable that each fixed shaft (10), whose lower end is axially fixed to the upper surface of the slab (S), simultaneously penetrates the cushioning pad (30) together with the resonance pipe (20).

[0047] The operation and effects of the inter-floor noise blocking device for a building according to the present invention, as described in the above configuration, are explained in more detail as follows.

[0048] The present invention allows the lower end of a fixed shaft (10) to be embedded in a slab (S) that partitions the floors during construction of a building, and then a resonance pipe (20), a cushioning pad (30), and a urethane foam layer (40) formed on the upper and lower parts of the combined assembly to be placed on the upper part of the slab (S).

[0049] In other words, the present invention is configured to cushion and block impacts caused by vibrations, etc., along with inter-floor noise in a slab (S).

[0050] As a configuration for this purpose, resonant pipes (20) are arranged in a unidirectional manner at uniform intervals in the slab (S) as shown in FIG. 5, and the upper and lower outer surfaces are alternately wrapped by cushioning pads (30) in which two or more of these resonant pipes (20) are stacked.

[0051] By wrapping the outer surface of the resonant pipe (20) that forms an internal space with two or more cushioning pads (30), the shock transmitted from the top is cushioned while the noise is absorbed.

[0052] In addition, as shown in FIG. 6, a urethane foam layer (40) is formed by filling the combination of the resonant pipe (20) and the cushioning pad (30) with urethane foam at the top and bottom to a predetermined height.

[0053] In particular, shock and noise applied from the top are first attenuated by the upper urethane foam layer (40) before reaching the combination of the resonant pipe (20) and the cushioning pad (30), thereby further increasing the shock cushioning and noise attenuation by the resonant pipe (20) and the cushioning pad (30), and are further offset by the lower urethane foam layer (40), so that the transmission of interlayer noise is completely blocked.

[0054] In addition, when the load impact applied to the upper concrete finishing layer (50) exceeds a certain level, the concrete finishing layer (50) is supported on the fixed axis (10) along with the finishing material (60) as shown in FIG. 7, and the combination of the resonant pipe (20), the cushioning pad (30), and the urethane foam layer (40) can be lowered slightly while contracting, thereby allowing the load impact to be completely eliminated.

[0055] A side wall (W) is formed on the side wall (W) forming surface of the concrete finishing layer (50), and the concrete finishing layer (50) between these side walls (W) is finished with a finishing material (60), or a heating pipe layer is formed and then finished with a finishing material (60).

[0056] 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
