Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an interlayer noise-damping board having a nonwoven fabric and a waterproof layer,

The present invention relates to an interlayer noise barrier board having a nonwoven fabric and a waterproof layer, and more particularly, to an interlayer noise barrier board having a nonwoven fabric and a waterproof layer, and more particularly, The present invention relates to an interlayer noise damping board.

Generally, the floor impact sound transmitted from the upper layer to the lower layer is a solid sound transmitted through the vibration of the structure, and the sound characteristics are changed according to the source of occurrence.

A light impact sound is a sound of a relatively light and hard impact source, such as a sound when the chair is turned off. Lightweight impact sound can properly block interlayer transmission by using sound absorbing material or sound insulating material.

On the other hand, the heavy impact sound is a bass caused by a heavy and soft impact source such as walking, and can be a serious problem when living barefoot in the room. To this end, it may be effective to increase the slab rigidity, such as by increasing the thickness of the bottom slab.

The anti-vibration board having the interlayer noise reduction structure of the prior art 1 for the interlaminar noise cushion is formed in a plate shape having a certain width and is laid on an interlayer floor of an apartment house such as an apartment or a billy. A synthetic resin pad formed to absorb impact generated from the upper layer as a form; An upper load support plate configured to support a load applied to the synthetic resin pad in a curable panel form; A synthetic resin mount configured to support each corner point of the upper load support plate and to absorb impact transmitted from the upper load support plate as a block having a predetermined size with a predetermined elastic modulus; And a heat insulator formed at a space between the synthetic resin mounts and spaced apart from a lower end of the synthetic resin mount by a predetermined height; .

However, the anti-vibration board having the interlayer noise reduction structure of the prior art 1 is placed on the concrete slab layer and is closed with the cement mortar on the concrete slab layer. Since the position is not fixed to the concrete slab layer, There is a problem that the position is changed.

The floor sound insulation structure for preventing the interlayer noise of the prior art 2 and the construction method thereof include a slab foundation layer; A sound insulating layer having an occupied ratio of 60% to 90% of PET (ethylene-vinyl acetate copolymer) and PET (polyethylene terephthalate) mixed on a top surface of the base layer at a predetermined ratio; An anti-penetration layer formed on the upper surface of the sound insulating layer and made of a waterproof sheet to prevent penetration of moisture and foreign matter; A mesh layer in the form of a mesh structure laminated on the top surface of the anti-penetration layer; And a mortar layer disposed on the upper surface of the mesh layer, wherein the pulverized EVA particles are scattered to form a predetermined gap between the EVA particles, and the pulverized PET particles are aggregated with each other, Thereby forming a flocculated structure.

However, in the bottom sound insulation structure for preventing the interlayer noise of the conventional art 2 and the construction method thereof, the anti-penetration layer, the mesh layer and the mortar layer are sequentially laminated in a state in which they are seated without being fixed on the base layer. There is a problem that defects occur.

"And"

Quot ;, or the like, or a combination of two or more of them, and the sound-absorbing portion 114 is symmetrical with the shape of the movement preventing portion 112.

In particular, at least one of the movement preventing portion 112 and the sound absorbing portion 114 is disposed in an oblique direction to prevent the durability from deteriorating. If the movement preventing portion 112 and the sound absorbing portion 114 are disposed on the same vertical line, the distance between the uppermost point of the movement preventing portion 112 and the lowest point of the sound absorbing portion 114 is small It may be broken, so that it is arranged in a diagonal position to prevent it.

The movement preventive portion 112 prevents the movement of the interlayer sound absorbing board 100 when the interlayer sound absorbing board 100 is seated on the upper surface of the lower mortar layer 20, Is formed on the protruding portion 22 of the lower mortal layer 20 formed in a shape corresponding to that of the lower molar layer 20.

The movement preventing portion 112 may be provided with a deformation preventing member 116 having a shape corresponding to a depressed shape and formed of a hard material. (See Fig. 5)

At this time, the deformation preventing member 116 is formed in a shape corresponding to the shape of the movement preventing portion 112 when the pad 110 is soft, and the pad 110 is moved from the protruding portion of the protruding lower molten layer 20 And is provided to be attached to the movement preventing portion 112 to solve the problem.

The sound-absorbing portion 114 is formed on the upper surface of the pad 110, so that noise generated in the floor of each building floor is absorbed, so that the sound-absorbing effect can be enhanced.

As a result, the sound-absorbing portion 114 is formed in a shape in which the area of the sound-absorbing portion 114 gradually decreases as the shape of the sound-absorbing portion 114 is downward. In contrast to the phenomenon of expanding the sound generated in a narrow area such as a trumpet, So that the noise of the room is absorbed.

The waterproofing layer 120 is seated on the upper surface of the pad 110 on which the sound absorbing part 114 is formed to impart a waterproof function to the pad 110. Polyethylene (PE) .

When the upper mortar layer 30 is formed on the surface of the nonwoven fabric layer 130 by being finished on the waterproof layer 120, the surface of the nonwoven fabric layer 130 is coarse due to the nonwoven fabric characteristic during the curing process, so that the bonding strength with the upper mortar layer 30 is improved, It is also possible.

Therefore, the construction procedure of the interlayer noise damping board 100 having the nonwoven fabric and the waterproof layer according to the present invention is as follows.

First, the lower mortar layer 20 is worked on the cement layer 10 constituting each layer of the building, and the movement preventive layer 20 is formed on the bottom surface of the pad 110 of the buffer board 100 when the lower mortar layer 20 is worked. So that the projecting portion 22 is formed at each position corresponding to the portion 112.

Next, the interlaminar noise-damping board 100 is placed on the lower mortar layer 20, and a movement preventing portion 112 formed on the bottom surface of the pad 110 is formed on the protruding portion 22 of the lower mortal layer 20 .

Next, the upper mortar layer 30 is worked on the nonwoven fabric layer 130 provided on the uppermost layer of the interlaminar soundproofing board 100, and the surface of the upper nonwoven fabric layer 130 is rough ) Is improved and sound absorption is also possible.

Next, the pipe embedding layer 40 in which the pipe 42 is buried is closed on the upper mortar layer 30 and closed with the finishing layer 50 on the pipe embedding layer 40.

The interlayer noise barrier board 100 having the nonwoven fabric and the waterproof layer of the present invention constructed in this manner has the movement preventing portion 112 formed on the bottom surface of the pad 110 to prevent the lower matal layer The waterproof layer 120 prevents the moisture from penetrating into the waterproof layer 120 and prevents the moisture from penetrating into the waterproof layer 120. In addition, It is possible to improve the binding force with the upper mortal layer 30 and to absorb sound.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. This is possible.
