Description
A SHOCK ABSORBING COMPOSITION FOR INTER LAYER NOISE PROOFING OF A CONSTRUCTION AND FLOOR FORMING METHOD USING THE SHOCK ABSORBING
COMPOSITION Technical Field
[1] The present invention relates to a shock absorbing composition for inter layer noise preventing of a building and a method of forming a floor of a building using the same, and more particularly, to a shock absorbing composition for inter layer noise preventing of a building and a method of forming a floor of a building using the same, in that a waste tire, a cork, a waste Styrofoam, a cement, and a foaming agent are reciprocally mixed, whereby it can prevent the inter layer noise of a multistory building such as an apartment building or an office building and so on.
[2] The present invention also, relates to a shock absorbing composition for inter layer noise preventing of a building and a method of forming a floor of a building using the same, in that a plaster is selectively mixed to the composition in order to decrease the curing time of the cement, so that the initial degree of strength is heightened, whereby improving the work efficiency during the wiring work of heating coils in twenty four hours.
[3]
Background Art
[4] In order to reside many people or fulfill many establishment, a high-rise apartment building or a shopping building are required.
[5] In such a multistory building, since the noise generated from an upper story thereof can be transmitted to a lower story thereof, the resident of the downstairs can feel much inconvenience. It can even bring in a lawsuit against the noise problem.
[6] In the multistory building, a bottom shock sound is discharged to the lower story through a floor slab, a ceiling, or a wall while a shock is generated in the floor of the upper story of an apartment house owing to a man's walking or the fall of an object. Generally, the concrete slab shuts out the air sound wave well. However, in the concrete structure, where a shock or a vibration are directly applied to it, they are changed to a solid sound wave and transmitted to an adjacent house without damping.
[7] In case of the West, since the shock sound is mainly generated from the walk of shoes or high heels, the household has a structure for preventing a weight shock sound. In the meantime, in case of Korean or Japanese house, since the peoples mainly live with sitting on the floor of the house, the household thereof has any structure for preventing a light shock sound as well as the weight shock sound.
[8] In case of the apartment house such as an apartment building or row houses, a dispute continuously arises between up and down stories on account of the vibration and noise between them. Also, it can even bring in a lawsuit between neighbors against the noise. In order to solve this problem, a foamy concrete is placed on a pad for absorbing a shock laid on the slab and then, a mortal is placed on the foamy concrete so as to diminish the noise between floors.
[9] In the conventional noise preventing method, there is a problem in that the noise preventing structure and method are complicated and the necessary time is very long, so that a cost of labor is increased, thereby it can be major cause for high cost of the apartment house.
[10] Also, the conventional noise preventing methods, since the shock materials and so on are constructed on only floor, the noise and vibration can be directly transmitted to the down story through the wall without absorbing all light and weight shock sounds.
[11] Actually, as though the first-class is accepted in efficiency test by using a test piece by means of a method of a KS F 2810 1,2, the actual apartment house is not first-class. Also, since it examines not the wall but only floor, the test result is not in keeping with the reality.
[12] Also, by the request of a resident, it can use a material lumber as a finishing material of the floor of the apartment house (especially a living room). In this case, the floor includes the concrete slab having a iron, a light foamy concrete for insulation formed on the concrete slab, a finishing mortal having a heating pipe and applied to the light foamy concrete, and the material lumber as the finishing material attached to the finishing mortal by means of an adhesive.
[13] In the floor structure using the material lumber, since the material lumber itself serves as a noise preventing material to some degree, a separated absorbing material is not used, thereby it can effectively shut out the floor shock sound.
[14] Also, in case of using a monorium (floor material) instead of the material lumber as the finishing material of the floor, a shock absorbing material such as a polyester is formed between the concrete slab and the light foamy concrete in order to shut out the floor shock sound. However, because a shock absorbing material is separated from the floor surface far away, the floor shock sound cannot be directly shut out. Also, since it can shut out the floor shock sound after the shock sound is transmitted to the light foamy concrete, there is a problem in that the efficiency of the noise prevention and the construction is deteriorated.
[15] Moreover, in the conventional method of construction, it binds gravel with cement by means of the processes of 4-5 steps and a separate elastic matt and so on are formed on the hardened cement in order to decrease the noise. However, there is a defect in that the necessary time is very long and a cost of labor is increased, thereby increasing a cost of the construction.
[16]

[24] Preferably, the shock absorbing composition contains 0.01-10 parts by weight of a sedimentation prevention agent relative to 100 parts by weight of the shock absorbing composition.
[25]
Advantageous Effects [26] As described above, according to the shock absorbing composition for inter layer noise preventing of the building and the method of forming the floor of the building using the same, the floor for preventing the inter layer noise can be easily constructed on the multistory building such as the apartment building or the office building and the floor forming process can be completed at one try, whereby reducing the building costs, forming a silent indoor atmosphere, and improving the durability on shock.
[27] Also, unlike the conventional art, as though the thickness of the floor becomes thin, it can absorb the light shock sound having much high frequency ingredients such as the falling sound of a golf ball or a moving sound of a chair, and the weight shock sound having much low frequency ingredients such as the walking sound of a man or a jumping sound of a child, whereby preventing the transmission of the sound and maintaining the warmth.

[60]
[61] Experimental example 1
[62] 300kg of a water, 8kg of a flowing agent, and 8kg of a bentonite are injected into a mixer with a capacity of 1.3D to be stirred and then, a foam of a predetermined amount generated from a foaming generator is injected into the mixer. Thereafter, 50kg of waste tire chips, 8kg of Styrofoam chips and 30kg of cork chips about 20mm in particle diameter respectively and 360kg of a cement are injected and stirred into the mixer to prepare a shock absorbing composition of ID and then, the shock absorbing composition is placed on a slab having 15 layers and a thickness of 150m/m to a thickness of 70m/m by using a placer.

[64] Then, a test piece for thermal conductivity is obtained from a mold having
30cmx30cmx5cm in length, width and height and the thermal conductivity thereof is measured, thereby meeting with a superior result (measurement value: 0.063W/m.K; 0.64 converted at the rate of overall heat transmission). As a result of a noise test, it can produce good results of 45dB (weight sound) and 47 dB (light sound).
[65] Also, it does not matter in higher stories. [66]
