Description

FLOOR PANEL FOR DIMINISHING A IMPACT SOUND AND ONDOL SYSTEM USING THE SAME

Technical Field

[1] The present invention relates to a floor panel for diminishing impact sounds in a building, and more particularly, to a floor panel for diminishing impact sounds in an apartment and a floor heating system using the same. Background Art

[2] In a multistory building including apartments, there is a need for a sound-resistant material for effectively shielding and absorbing vibration sounds, impact sounds, and other sounds to provide pleasant surrounding environments to residents in the building. With the advancement of civilization, especially, peoples who live in the apartments are drastically increased, but most of them feel uncomfortable in their living environments whenever they suffer impact sounds. Therefore, there is a definite need for the lawful regulations and the improvements in the construction sites for reducing the impact sounds in the building.

[3] Most of concrete buildings inclusive of apartments are formed of a structure connected by walls and floors each having a general thickness between 120mm and 200mm. As well known, the concrete material has given rigidity capable of sufficiently protecting air born sounds like talking sounds and television sounds. On the other hand, the concrete material is substantially weak in diminishing vibration generated from itself, such that the structure born sounds generated when impact is directly applied to the concrete surface are easily transmitted to the adjacent rooms thereto. Such the structure born sounds include upstairs floor impact sounds such as sounds generated when running or walking, sounds when an object falls, sounds when doors are opened and closed, sounds while a hammer is used, and sounds generated from drainage or sewage pipes. The structure born sounds undesirably give mental fatigue, sleep disturbance, and concentration difficulties to the apartment residents, which is one of causes for creating severe society problems.

[4] The floor impact sounds include light-weight impact sounds and heavy-weight impact sounds. Since the light-weight impact sounds have a relatively low impact force, they can be somewhat absorbed through a soft elastic material like a carpet upon finishing the floor, but since the heavy-weight impact sounds have a relatively large impact force, they can not be absorbed well through the finishing material. Moreover, floorings for under heating systems (Ondol heating system) are widely utilized for the conveniences of cleaning and the prevention of warm cultivations, but they fail to reduce even the light-weight impact sounds.

[5] On the other hand, a system that is recently used for the apartment floorings includes a finishing layer structure having a light-weight bubble concrete layer and cement mortar. The system does not have any sound insulation layer (a buffering layer), and thus, it does not have any performance for insulating the floor impact sounds. Under the flooring system, really, the floor impact level of the light-weight impact sounds is placed very high at medium and high bands, and the noise level of the heavy-weight and light-weight impact sounds is also placed very high. So as to diminish the floor impact sounds, thus, the floor concrete slab has to have a thickness of 210D or more, and excellent sound insulation materials should be chosen desirably. Disclosure of Invention Technical Problem

[6] Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a floor panel for diminishing impact sounds in a building and to a floor heating system using the same. Technical Solution

[7] To accomplish the above object, according to an aspect of the present invention, there is provided a floor panel for diminishing impact sound including: a core having a shape of a sheet and a plurality of holes formed at the inside thereof; a pair of buffering layers disposed on and below the core; and a base sheet disposed on the upper buffering layer, wherein the base sheet, the pair of buffering layers, and the core are laminated on top of one another as an integral body .

[8] Preferably, the core is formed in a shape of a lattice or honeycomb core, and it is water-resistant. Particularly, since the core has a plurality of holes formed at the inside thereof, it is lighter than general sheets, while being resistant to large load. Further, the core keeps its own smoothness, with no deformation thereon.

[9] The pair of buffering layers serve to absorb and insulate the force impact sounds, and they are formed of compressed glass wool, compressed polyester, polyurethane, a sound absorbing and heat insulating material in an open cell structure, foaming rubber and so on. Especially, since the compressed glass wool, the compressed polyester, and the polyurethane are compressed and molded at high density, an air layer is formed by the core disposed between the pair of buffering layers, thereby advantageously improving the heat insulation effects. Further, the sound absorbing and heat insulating material or the foaming rubber has an excellent sound-absorbing performance capable of removing the resonance between the concrete slab and the cement mortar, thereby advantageously optimizing the floor impact sound decreasing effects. [10] The base sheet is formed of steel, aluminum, plywood or plastic. The base sheet generally serves to protect the upper buffering layer from the invasion of foreign materials like concrete and cement mortar to be poured thereon. Additionally, in a case where the floor panel of the present invention is employed in the floor heating system, the base sheet serves to fix a heating pipe thereto. In this case, if the base sheet is formed of a metal material having high thermal conductivity like steel and aluminum, it can more effectively emit the heat transmitted from the heating pipe to the outside, thereby optimizing the heating effects. Of course, the base sheet has a plurality of equally spaced heating pipe-fixing pins disposed thereon, for fixing the heating pipe thereon. The plurality of equally spaced heating pipe-fixing pins may be formed integrally on the base sheet, which makes the construction of the floor heating system easily conducted.

[11] To accomplish the above object, according to another aspect of the present invention, there is provided a floor heating system using a floor panel for diminishing impact sounds in a building. The floor heating system includes a concrete slab, a floor panel disposed on the concrete slab for diminishing the impact sounds, a heating pipe fixedly disposed on the top surface of the floor panel, and a finishing layer formed of cement mortar.

[12] When the floor panel for diminishing impact sounds is employed in the floor heating system, it is found that sound insulating, sound absorbing, and heat insulating effects are excellent. Further, the floor panel can be produced in great quantities and easily mounted on the floor of the building, thereby giving economical advantages in that the construction period is reduced and the construction costs are decreased. Additionally, the concrete slab can be thin in its total thickness, thereby providing savings in the construction costs. Brief Description of the Drawings

As shown in FIG.2, the plurality of equally spaced heating pipe-fixing pins 40 are disposed longitudinally in one direction in parallel relation with one another.

[33] FIG.3 is a sectional view showing the constructing state of the concrete slab made by using the floor panel of the present invention. The floor heating system using the floor panel for diminishing impact sounds in a building has the following structure.

[34] First, the floor panel 60 of the present invention is mounted on a concrete slab 50 constructed at a previous process. As shown in FIG.3, the floor panel 60 of the present invention wherein the lower buffering layer 10, the core 20, the upper buffering layer 11, the base sheet 30, and the plurality of equally spaced heating pipe-fixing pins 40 are formed integrally to top of one another is mounted on the concrete slab 50.

[35] At the corner where the concrete slab and a wall abut each other is provided a separating member 70 that comes into close contact with the wall in such a manner as to be vertically raised to the thickness of a finishing material like cement mortar, and the separating member 70 has a washboard 71 disposed above. Then, the heating pipe

41 is fixedly mounted to the plurality of equally spaced heating pipe-fixing pins 40 of the floor panel 60 of the present invention. On the uppermost portion of the heating system is provided the finishing material like the cement mortar 51. Thereby, the construction for the floor heating system using the floor panel for diminishing impact sounds in the building is finished.
