Description

Description
STRUCTURE FOR PREVENTING NOISE AND VIBRATION
WITH LIQUID BOX
Technical Field
[1] The present invention relates to a structure for preventing nose and vibration; and more particularly, to a structure for reducing shock or nose and vibration using a liquid box by passing a sonic wave and a vibration through liquid. Background Art
[2] Apartments and office buildings generally include a plurality of living spaces and office spaces which are sectored to upper levels and lower levels by a concrete slab. Such a concrete slab directly transmits noise and vibration generated at the upper level to the lower level. The transmitted noise and vibration seriously disturb residences or workers in the living space or the office space in the lower level. Accordingly, there were many studies in actively progress to reduce the noise and the vibration transmitted through the concrete slab.
[3] Among such studies for reducing the noise and the vibration, a noise prevention sheet was introduced in the Korea Utility Model No. 20-0337780. As shown in drawings of the Korean Utility Model No. 20-0337780, the noise prevention sheet 100 includes: a first textile layer 110 which is a lowest layer made of synthetic resin; a 3-D reticulate material layer 120 laminated on the first textile layer 110, which is made of the synthetic resin irregularly bended to form a plurality of protrusions and grooves; a second textile layer 130 made of synthetic resin laminated on the 3-D reticulate material mat layer 120; a third textile layer 140 made of synthetic resin laminated on the second textile material layer 130; a Styrofoam layer 45 formed on the third textile layer 140; and a silent sheet 160 laminated on the Styrofoam layer 150 as a shock absorber. Such a noise reduction structure 100 is formed on the concrete slab 10. Herein, a numeral reference 20 denotes a foamed concrete layer and a numeral reference 30 denotes a mortar layer. A number reference 32 denotes pipes for heating. Also, the noise prevention sheet 100 is disposed on the concrete slab 10.
[4] As another conventional technology, a structure of vibroisolating material for building was introduced in Korea Utility Model No 20-0312358. As shown in drawings of the Korean Utility Model No. 20-0312358, the conventional structure 11 is buried between a concrete slab 1 and a foamed concrete 12, and a finishing mortar layer 18 is formed on the foamed concrete 12. The conventional structure 11 has a thermal compressed multi-layer structure configured of a high density layer 15 made of a synthetic rubber deadening sheet, a medium density layer 16 made of a cross linked polyethylene (XLPE) foam and a low density layer 17 formed of an non cross linked polyethylene foam. Herein, the medium density layer 16 and the low density layer 17 may be formed under the high density layer 15 in sequence as shown in FIG. 2, or the medium density layer 16 and the low density layer 17 may be formed under and on the high density layer 15. A plurality of convexes and concaves 13 is formed on the high density layer 15 and air spaces are formed at the bottom of the high density layer 15 at a predetermined interval.
[5] That is, such conventional structures reduce the noise and the vibration using only a sound absorbing material or vibration proof, or by forming an air layer.
Disclosure of Invention Technical Problem
[6] It is, therefore, an object of the present invention to provide a structure for reducing nose and vibration using a liquid box for maximizing the reduction of the noise and the vibration in an air layer between sound absorbing materials by interposing the liquid box.
Technical Solution [7] In accordance with one aspect of the present invention, there is a structure for reducing noise and vibration including a sound absorbing panel including a liquid box containing liquid disposed at one side or both sides of the sound absorbing panel. [8] A plurality of liquid boxes may be disposed to be separated one another and air layers may be formed between the liquid boxes. [9] The liquid box 200 may be disposed to cover the entire surface of the sound absorbing panel. [10] A thermal insulating panel or a stiff ener panel may be interposed between the liquid box and the sound absorbing panel. [11] The liquid box may include supporting posts connecting the top and the bottom of the liquid box.
Advantageous Effects
[12] A structure for reducing noise and vibration using a liquid box according to the present invention dramatically reduces the noise and the vibration in short time by passing the noise and the vibration through liquid. [13] Also, the structure for reducing noise and vibration according to the present invention provides a stable structure by disposing supporting posts in the liquid box.
