Description

FLOOR CONSTRUCTION STRUCTURE OF BUILDING AND METHOD FOR CONSTRUCTING FLOOR OF BUILDING}

The present invention relates to a floor construction structure and a construction method of a building, and more particularly, to effectively absorb and exhaust (distribute) noise and vibration generated by an impact, and to provide excellent sound insulation and vibration resistance between layers. It relates to the floor construction structure and construction method of the constructed building.

In general, when constructing a multi-storey building such as a multi-family house or apartment, it is common that almost all work is performed at the construction site. In the case of apartments and the like, a prefabricated construction method using a precast method (PC method) is prevalent.

A general method of constructing a multi-story building is as follows.

First, the foundation works such as earthwork and ground compaction, and the skeleton structure of the building is formed on the ground using steel frame such as H-beam, I-beam. Specifically, after installing a plurality of steel frame in the vertical and horizontal direction, and then fastening the steel frame frame with each other by welding or bracket to form a skeleton structure of the building.

Next, bricks are laid between the vertically installed steel frames or formwork is formed to connect reinforcing bars to the inside, and then concrete is cast and cured to build walls. In addition, formwork (usually 'Eurofoam') is installed on the horizontally installed steel frame, wires are connected to the steel frame, and concrete is then poured and cured to build a slab. In this way, after pouring and curing concrete, a layer is formed by dismantling the formwork after a certain period of time. And several layers are built by repeating the installation of formwork, concrete placing and curing several times. The building constructed in this way is partitioned by walls and slabs so that several generations can live and have a multi-layered structure, while being divided into several living spaces on one floor.

At this time, in the construction of the slab floor of the building, it is important to block the noise and vibration of the floor (bottom and upper floors). Impacts from the upper floors, especially from severe fluctuations in children in apartments, can cause serious damage to the occupants of the lower floors. Accordingly, the installation of the cushioning material for shock absorption, and the sound insulating material for exhausting noise may be essential for the floor construction work of the building.

In order to prevent noise and vibration between the floors, a sound insulation / buffer material such as a rubber material or a synthetic foam is generally installed at the slab bottom. For example, Korean Patent No. 0166993 (Patent Document 1) lays a rubber material on a floor-based slab, forms a barrier layer by laying a polyethylene (PE) foam sponge on it, and then on the PE foam sponge that is the barrier layer. A method of constructing a floor shock sound-proof floor structure in which a floor layer (floor material) is adhesively formed is proposed. In addition, the Republic of Korea Patent Publication No. 10-2006-0038862 (Patent Document 2), which can be used as an interlayer noise prevention material (sound absorbing material) of the building, having a foaming ratio of 5 to 200 times, foaming of 10 to 3,000 ㎛ diameter Thermoplastic flame retardant foams with cells are shown.

However, the floor construction structure according to the prior art shown in the Patent Documents 1 and 2, even if the sound insulation / shock absorbing material as described above has a problem that does not effectively block the noise and vibration applied from the upper layer. As a result, the occupants of the lower floors are severely damaged by noise and vibration.

In addition, as proposed by the present inventors, Republic of Korea Patent No. 0757011 (Patent Document 3) is a concrete body having a lower plate and four side plates, embedded in the interior of the concrete body, fixed reinforcing member, the support reinforcing member A band-shaped metal plate coupled to the upper portion, coupled to the metal plate, the gap holding member coupled to have a hollow portion between the metal plate and the top plate, the height adjustment / shock buffer member coupled to the gap holding member, A concrete structure including at least two or more top plates coupled to the height adjusting / shock absorbing member is provided.

The concrete structure disclosed in Patent Document 3 has a dustproof property by absorbing the impact by the hollow portion and the height adjustment / shock absorbing member, which is difficult to install due to the complicated structure, somewhat lack of structural stability, effective sound insulation And the problem which does not aim at dustproofness is pointed out.

At this time, the concrete layer 36 is formed from a general concrete mortar, that is, a dough mixed with sand, cement and water, and the lightweight foamed concrete layer 37 is bubbled by mixing a foam forming agent with a general concrete dough Or a bubble is formed by air injection. Such a lightweight foamed concrete layer 37 is preferable because of its light weight and good sound insulation and heat insulation. In addition, the ocher layer 38, as described above, is intended to achieve the effect of deodorization, sterilization, far-infrared radiation, and the like, and the cooling / heating effect due to the role of the traditional Korean house's sweet field. Molded as a main material, molded by mixing fibers or rice straw with ocher, or molded by further mixing at least one selected from natural minerals such as clay, germanium, gangue stone, and charcoal.

In addition, the closing plate 30 is for strength reinforcement, it may have a structure in which the reinforcing member 39 is bound to the lower portion. The reinforcing material 39 includes a metal material and a plastic material.

At this time, the ocher plate 30 'is molded from ocher as a main material, but is molded from a mixture of reinforcing materials such as fiber or rice straw in ocher powder to have excellent tensile strength. In addition, the ocher plate 30 ′ is preferably pressed and molded using a dry dough added with a small amount of water, rather than a wet dough containing a large amount of water. In other words, if the viscosity is too high because the content of water is too low, because the mold release property is low and difficult to process, it is preferable to knead the molding in a dry form by reducing the water content and then compression. In addition, after pressing and molding in the dry form as described above, the surface property is inferior, so that it is preferable to dry it sufficiently and then polish the surface to have a smooth surface.

In addition, the finishing plate 30, for example, the ocher plate 30 'is preferably a reinforcement angle 30-1 is coupled to its edge. The reinforcing angle 30-1 is a quadrangular frame shape that can protect each corner to prevent cracking, and includes a metal material and a plastic material.

One piece may be purchased each time.

In addition, liquid may be accommodated in the sound absorbing material accommodating bag 60. In this case, when water is used as the liquid, freezing of the liquid may occur due to a failure of the heating facility in winter. In order to prevent such a freezing, the accommodation bag 60 is preferably mixed with a cryoprotectant together with a liquid. Such cryoprotectant may be used as long as it can prevent freezing, for example, calcium chloride, sodium chloride, alcohols and glycols, etc. may be used, preferably water-soluble alcohols having 1 to 5 carbon atoms Or a single compound selected from glycols, or a mixture of two or more thereof. More specifically, the cryoprotectant may be used by mixing one or two or more selected from ethylene glycol, propylene glycol, methanol, ethanol, isopropanol, 2-butanol, 1-pentanol and the like.
