Description

Tray-type inter-floor noise reduction structure {TRAY-TYPE FLOOR NOISE REDUCTION STRUCTURE}

The present invention relates to a tray-type inter-floor noise reduction structure, and more specifically, to a tray-type inter-floor noise reduction structure with excellent floor impact noise reduction effect, excellent insulation performance, flame retardancy performance, and water blocking performance.

In most current residential interfloor structures, first, a floor impact sound blocking layer is installed on the upper surface of the interfloor concrete slab, and then foam concrete is poured on top of it at the construction site. After a predetermined curing period, hot water pipes for heating are installed on the foamed concrete layer, finishing mortar is poured on top of it, and finally floor finishing materials such as flooring, wooden flooring, and marble are installed to form the floor structure.

However, it was not possible to fundamentally block floor impact noise with this inter-floor floor structure construction method. Accordingly, in order to solve this problem, the Ministry of Land, Infrastructure and Transport revised the “Regulations on Housing Construction Standards, etc.” in 2013 to set the slab thickness of apartment buildings at 210 mm or more, and designed to satisfy 58 dB or less for light floor impact noise and 50 dB or less for heavy floor impact sound. The standards have been strengthened.

This strengthening of floor impact noise standards not only increases problems such as increased construction costs, building load problems, and environmental issues, but even now that slab thicknesses of 210 mm or more are being applied, problems with complaints about inter-floor noise are increasing every year. .

In addition, as described above, the general inter-floor structure consists of a double-layered floor structure in which a blocking material is installed on the upper part of the slab for the purpose of blocking inter-floor noise and is divided by a layer of foamed concrete formed on top of the blocking material for insulation. The floor structure constructed in this way is causing many problems.

Specifically, most floor sound insulation materials currently applied are made of organic compounds such as Styrofoam, foamed rubber (EVA), and polyester, applied to the upper part of the slab, and are composed of a wide plate shape. Wide plate-shaped sound insulating material has the advantage of being easy to construct and shortening the construction period. However, the flatness of the upper surface of the slab is insufficient, so if it is not installed in close contact with the slab layer, noise between floors occurs due to the resonance phenomenon of impact noise. There is a problem that needs to be addressed.

In addition, these sound insulating materials have limitations in satisfying the Korean standard standards for dynamic elastic modulus (after heating) (KS F 2868), dimensional stability (after heating) (KS M ISO 4898), and density (KS M ISO 845).

In addition, foam concrete is generally used at construction sites for the purposes of insulation performance, soundproofing performance, and lightness. The foamed concrete construction method involves mixing Portland cement with water using a stirrer equipment, adding a foaming agent, going through a foaming process, and constructing it through the pumping piping of a pump car. This construction method has problems such as impossibility of construction in winter due to deterioration of air bubbles, prolonged construction period due to curing period, and problems such as reduced insulation performance and lack of sound absorption effect.

In addition, since foamed concrete is composed of cement, water, and foaming agents and does not use aggregates such as sand, its compressive strength is lower than that of regular concrete, which can lead to cracks and, in severe cases, even damage.

In addition, foamed concrete is made up of a method of pouring finishing mortar by forming a heating pipe on the upper surface of the foamed concrete, and has the advantage of excellent durability because the finishing mortar and foamed concrete are combined. However, when floor impact noise occurs, there is a problem that the low-frequency weight impact sound reduction effect among inter-floor noise is insufficient because the finishing mortar and foam concrete are composed of one piece and a whole plate.

In addition, the purpose of foam concrete is to provide insulation performance and sound absorption performance by causing foaming, but not only is the mixing ratio not constant when pouring foam concrete on site, but also the distribution and rate of foam generation and density are not constant depending on climatic conditions. Therefore, there is a problem of deterioration of insulation performance and sound absorption performance.

In order to compensate for this problem, a method of adding EVA CHIP, EPS BEAD, etc. to the foam concrete on-site and constructing it as an integrated structure on the top of the slab (Korean Patent Registration No. 1529630) has been disclosed, but this method applies separate sound insulation and insulation materials. The disadvantage is that the insulation and sound insulation performance are insufficient.

Therefore, a tray-type inter-floor noise reduction structure that has excellent floor impact noise reduction effect and excellent insulation performance, flame retardancy performance, and water blocking performance is needed.

It has a attenuating effect.

The tray portion 1110 prepared in this way is made of plastic synthetic resin and may have a thickness of 1 to 1.5 mm.

Additionally, the tray portion 1110 may be prepared to be vacuum-compressed in a mold heated to 50 to 60°C.

In addition, although not shown, a tray support (not shown) protruding upward and extending in the horizontal and vertical directions may be further formed on the upper surface of the tray flooring material 1111. The tray support formed in this way can improve the bending rigidity of the tray flooring material 1111.

Specifically, the filling part 1200 may be provided to fill the tray flooring material 1111 up to the height of the tray wall 1112.

And the filling part 1200 is a powder binder made of Ftland cement or white cement, and blast furnace slag, and is functional, further containing one or more lightweight aggregates among pore-containing perlite, bottom ash, EPS BEAD, and waste gypsum board pulp. It could be mortar.

In addition, the filling part 1200 is a functional mortar formed by stirring the powder binder and the lightweight aggregate by dry mixing, then adding a binder containing sodium hydroxide to water and stirring it a second time. It can be prepared with

In addition, the filling part 1200 may be characterized by using materials such as perlite, bottom ash, and EPS BEAD containing pores to provide lightness and insulation without using a foaming agent that weakens durability.

The perlite used in the present invention may be expanded perlite. Specifically, when a mineral selected from the group consisting of perlite, obsidian, pumice, etc. is finely pulverized and heated to 900-1200°C, the volatile components of perlite contained in the crude perlite rock are gasified and the softened particles are It expands internally. When the pearlite raw material expands like this, internal pores are formed and it expands to about 10 to 20 times the original volume, forming expanded pearlite. In the present invention, such expanded pearlite is used, and the expanded pearlite particle size is preferably 2 to 4 mm.

Porous bottom ash is a substance formed by sintering in the combustion furnace of a thermal power plant, and the solidified material that falls to the bottom of the boiler is pulverized to a particle size of 25 mm or less using a grinder. In general, bottom ash crushed by a crusher has a particle size range of about 1 to 10 mm and is also called clinker ash or bad ash. The appropriate particle size of the bottom ash used in the present invention is 3 to 5 mm.

Blast furnace slag is generated in a blast furnace in the steelmaking process, and hydration reaction occurs rapidly under certain conditions. This characteristic of blast furnace slag is called latent hydraulicity. When OH- is adsorbed to blast furnace slag particles by an alkali stimulant, the glass structure is destroyed and the elution of SiO ₂ , Al ₂ O ₃ , CaO, and MgO is promoted. In other words, when the film structure of the SiO ₂ -based three-dimensional network structure that constitutes the glass structure of blast furnace slag particles is cut by a strong alkali of pH 12 or higher, CaO, MgO, Al ₂ O ₃ , etc. in the film structure can easily be eluted. A reaction can begin. The blast furnace slag fine powder used in the present invention has an appropriate powder size of 3,000 to 10,000 cm ² /g.

In addition, it has excellent initial strength development and can significantly shorten the curing time by demonstrating a compressive strength of 20 to 40 MPa per day even at room temperature of 20°C.

The pulverized pulp of waste gypsum board used in the present invention can be used to reinforce the bending strength of the product. Specifically, gypsum fine powder formed by finely pulverizing waste gypsum boards generated at construction sites is used as an additive in ready-mix concrete manufacturing plants, but paper powder laminated to gypsum boards has little use. In the present invention, fine powder pulp generated from waste gypsum board can be applied and used as a bending strength reinforcement agent for products.

The EPS BEAD used in the present invention is an expanded polystyrene bead and can be used to enhance crack prevention, lightweight performance, and insulation performance.

More specifically, the manufacturing method of the functional mortar forming the filling portion 1200 will be described as follows.

First, 40 to 60% by weight of Portland cement or white cement, 5 to 10% by weight of blast furnace slag, 20 to 30% by weight of powder binder and bottom ash, 5 to 8% by weight of perlite, 3 to 5% by weight of EPS BEAD, and waste gypsum. The first mortar can be formed by adding lightweight aggregate such as 5 to 8% by weight of board pulp into a stirrer and performing first dry mixing.

Then, 40 to 50 wt% of the binder mixed with 95 to 97 wt% of water and 3 to 5 wt% of sodium hydroxide and 50 to 60 wt% of the initially dry mixed mortar were put into the stirrer and stirred a second time to form a functional mortar. can be manufactured.

The filling part 1200 prepared in this way is made of a dry type, so the curing period is short, so the construction period can be shortened, the occurrence of cracks is reduced, and the insulation performance and sound insulation performance are excellent.

The binding unit 1316 extends further upward from the extension unit 1315 and may be provided to be inserted into the binding hole 1130 of the tray unit 1100. In this way, when the binding unit 1316 is inserted and fitted into the binding hole 1130, the sound-absorbing material 1140 applies an external force to prevent the diameter of the binding hole 1130 from increasing and is provided to relieve shock in the vertical direction. It can be.

The first vibration isolator 1320 may be coupled between the slab 10 and the mount body 1310 to absorb impact sound.

The second dustproof material 1330 may be made of polyester sound absorbing material.

The glass wool 1400 may be laminated on the top of the filling part 1200 or between the slab 10 and the mount part 1300. At this time, the glass wool may be changed to mineral wool.

Specifically, after dry construction of the filling part 1200, flame retardant glass wool (Glass Wool, 1400) or polyester wool, which has excellent insulation and sound absorption performance, is installed on the upper part of the filling part 1200, and the upper part of the glass wool (1400) is installed. The tray unit 1100 including the mount unit 1300 can be installed. At this time, the glass wool 1400 uses a product with silver foil laminated on the top or both sides. By doing this, not only can moisture from the glass wool 1400 or polyester wool be prevented from penetrating into the finishing mortar poured on top, but the heating effect can be increased by radiant heat generated by the silver foil.

In addition, an insulating and sound-insulating portion of glass wool 1400 or polyester wool may be formed on the top of the slab 10 to supplement the excellent thermal insulation and sound-absorbing performance.

As another example, polyester wool may be installed on top of the slab.

The polyester wool is an environmentally friendly material that is harmless to the human body. The polyester wool prepared in this way is made of an eco-friendly material that does not cause dust generation such as weathering or scattering.

In addition, the polyester wool has excellent flame retardancy and moisture stability, and in the event of a fire, the low melting point polyester component melts at low temperature and covers the flame to prevent the flame from progressing, and no toxic gas is generated even during combustion. In addition, polyester fiber has excellent moisture stability, which is a unique characteristic of polyester fiber, so it is not only easily drained (humidity rate 0.07%), but also maintains its original strength even after draining. In addition, the polyester wool has excellent sound absorption, insulation, flexibility, lightness, flame retardancy, moisture stability, and environmental stability compared to widely known construction materials such as conventional Styrofoam, MDF, plywood, gypsum board, and Myton.

Additionally, the magnesium sound insulation board may be provided by being further laminated on top of the glass wool 1400.

The magnesium sound insulation board is an eco-friendly building material that is harmless to the human body, and is non-absorbent, so it is resistant to moisture and has antibacterial properties, preventing mold and bacteria from growing. In addition, the magnesium board is a fire-resistant, non-combustible material, does not generate toxic gases even when burned in a fire, and is not harmful to the human body like asbestos. In particular, magnesium boards have excellent noise blocking performance.

The above magnesium sound insulation board can be provided with a thickness of 2.8 to 3.2 mm. If the thickness is less than 2.8mm, there may be difficulties in securing water resistance, fire resistance, and bending strength. Conversely, if the thickness exceeds 3.2 mm, it may act as a factor in increasing manufacturing costs and weight without further increasing the effectiveness, making it uneconomical.
