Description

In this paper, we propose a floor-to-

More particularly, the present invention relates to a floor-to-floor sound insulation floor structure of a multi-storey house, more specifically, to provide a sound insulation space in a slab, to absorb vibration of a slab in a floor space in the sound insulation space to reduce noise, To a floor structure of an inter-layer sound insulation of a multi-unit house which blocks noise from being transmitted to the floor.

Generally, a typical construction method of two or more stories such as apartments or apartment houses is to construct a concrete slab according to the number of the buildings, complete the foundation work, and then place heating pipes on the concrete slab at regular intervals The gravel and the cement mortar are constructed to have a predetermined thickness.

Thus, slabs dividing layers and layers of multi-layered multi-storey buildings such as apartments, high-rise buildings, etc., are constructed only by concrete, so that vibration due to noise and impact generated in the corresponding layer of the building is directly transmitted through the inter- .

The impact sound applied to the building structure of apartment houses and villas is transmitted to all directions due to the impact of the person's walking, opening and closing of the door, moving of the equipment, operation or stop of the equipments, As a result, the surface of the building structure is vibrated as well as being converted into air transmission sound, which is perceived as noise when it is heard by people around the ear.

For example, a sound such as a falling object is applied to the floor or a sound of moving a chair generates a solid sound, and the sound transmitted through the floor slab to the lower layer is referred to as interlayer noise.

Nowadays, this kind of interstory noise problem is seriously arising in a multi-family house, and the government announced that it will impose a penalty by applying the crime of disturbance of the misdemeanor punishment law to the interstice noise induction act, and even the stranger noise, And the regulations on housing construction standards, etc. have been strengthened and revised.

The above provisions stipulate that floor impact sound between each floor should be less than 58 decibels (dB) for light impact sound, 50 dB (dB) or less for heavy impact sound, or standard floor structure notified by the Minister of Construction and Transportation.

Conventional interlayer floor structures for minimizing the interlayer noise so as to reduce the severely interlayer noise are proposed. In the conventional interlayer floor structure, a lightweight foamed concrete layer is formed on the basis of a concrete slab, A heating pipe and a mortar layer for finishing, and a floor decoration layer made of a decorative material such as monolith, wood, or tile.

However, the above-mentioned interlayer bottom structure is responsible for attenuating the noise by the lightweight foamed concrete layer formed on the concrete slab, but it is not able to properly absorb or block the noise such as the light impact sound and the heavy impact sound.

Therefore, when the building is constructed with such a conventional floor structure, for example, the noise and vibration caused by the impact applied to the floor due to the children running upstairs are directly transmitted to the lower layer, resulting in a significant deterioration in the comfort of the building.

As a result, many kinds of interlayer noise-proofing materials have been developed in order to more effectively block noise or impact. However, since all of them are closely attached to the concrete slab surface of the apartment house, the noise-blocking effect is not significant.

For example, the conventional interlayer noise preventing material has a disadvantage in that noise is not blocked because the lightweight foamed concrete and the mortar are laid on the slab surface of the apartment house mainly by the styrofoam heat insulating material or other synthetic resin foam sheet.

In addition, an interlayer noise preventing material using rubber chips and foamed polyester obtained by pulverizing waste tires has been used, but it has not been popularized because it can not be mass-produced in reality and is not economical.

In other words, waste tires, which are the raw materials of rubber bodies, have advantages of easy recycling as well as recycling of resources. However, they are scattered all over the country, so they require a lot of logistics cost for collecting, The manufacturing cost of the rubber chip is inevitably high.

In order to have the function of the rubber chip as an interlayer noise preventing agent, it is necessary to impregnate tar and to adhere foamed polyester having an appropriate thickness to one side or both sides thereof. However, Since it takes a lot of adhesive due to the surface, it is also pointed out as a factor of price increase. Due to the high price, it is applied only to some high-grade housing, but it is not widely spread. Since the manufacturing facility is also not economical, Mass production can not be achieved.

In addition, the interlayer noise prevention material using the rubber chip and the foamed polyester uses the pore, the restoring force and the elasticity, and the thicker it is, the higher the effect is obtained. Therefore, in order to obtain the noise prevention effect as necessary for the residential use, Since the interlayer noise preventing material having such a structure is divided into a plate material type due to the characteristics of the material, it is inconvenient for handling and storage because it can not be formed in a long length during manufacture, and construction work is very troublesome due to the frame construction. There is a problem.

In the patent document (Registration Utility Model No. 20-0309422), a lightweight foamed concrete layer, a mortar finish layer for inserting a hot water pipe, and an interior flooring layer are sequentially formed on the upper part of the floor slab of the apartment house, And a sound insulating material including a sound absorbing pad and a sound absorbing pad. The sound insulating material is laid between the vibration diffusion layer and the lightweight foamed concrete layer so that the impact vibration of the upper layer generation is weakly formed in the vibration diffusion layer The sound absorption effect is very weak and the noise reduction effect is weak, so that a large noise is transmitted to the lower layer.
