Abstract

The present invention relates to an interlayer noise-blocking panel, characterized in that it is produced by attaching a fiber solidified plate impregnated with a solidified mixed solution to a nonwoven fabric of geotextile on both sides of a styrofoam of a predetermined thickness.

As described above, the interlayer noise and vibration blocking panel according to the present invention absorbs vibration by the elasticity of the styrofoam and promotes sound insulation by the airtightness of the styrofoam particles, while the high tensile strength of the fiber-fixed plates attached to both sides withstands the mortar load on the upper side. When installed on the floors of apartments, multi-family houses, townhouses, etc., it can reduce the vibration and noise between floors. In order to improve the tensile strength of the styrofoam bottom surface and the upper plastering mortar layer for the purpose of thermal insulation, it is possible to omit the construction of the bubble concrete layer to be applied at the bottom, thereby reducing the construction thickness between layers.

Description

Floor noise vibration blocking panel {PANEL TO INTERCEPT NOISE AND VIBRATION BETWEEN THE FLOOR AND CEILING}

The present invention relates to a floor noise vibration blocking panel, and more specifically, to reduce the transmission of vibration and noise between floors in apartments, multi-family houses, tenement houses, officetels, and buildings, and to insulate and foam the styrofoam installed in the floor construction. The present invention relates to an interlayer noise-blocking panel that can omit concrete work.

In general, the floors and floors of apartments, multi-family houses, townhouses, officetels or buildings are divided by ready-mixed concrete. Styrofoam with a thickness of 1 ~ 2cm is installed on the ready-mixed concrete, and 4 ~ 5cm of foam concrete that can support the upper plaster mortar layer is placed on it, and the heating pipe is installed on the foam concrete layer. Floor work is completed by plastering mortar of ˜4 cm thick.

As the floor construction is performed as described above, the floor of each floor is integrated with the wall, so noise and vibration generated from the upper floor are transmitted to the lower floor through the floor and the wall floor. In this case, people living in the lower floor (residents or householders) ) Is uncomfortable due to noise and vibration.

In order to solve this inconvenience, by placing a dust-proof pad between the ready-mixed concrete and foam concrete during the floor construction, Republic of Korea Utility Model No. 192046 (Application No. 2000-6667, "Interlayer anti-vibration pads on the building floor", citation Devises) can suppress transmission of noise and vibration generated in the upper layer to the lower layer.

However, since the interlayer dustproof pad on the floor of the building has no adhesion with the foamed concrete on the upper side, the thermal expansion coefficient is different, and has a low flexural strength, the dustproof pad is subjected to the load of foamed concrete and plaster mortar disposed on the upper surface. You will receive a lot of warpage. Therefore, when the anti-vibration pad is partially pressed by such a high load, the foamed concrete and the plaster mortar on the upper part have a problem in that they are damaged when used for a long time.

In addition, since the anti-vibration pad is made of synthetic resin, rubber, etc., it is not bonded to the foamed concrete or plaster mortar on the upper side, so that an interface is formed, which may cause cracks in the mortar layer if used for a long time. Therefore, we have studied the interlayer noise and vibration blocking panel with good insulation strength, high tensile strength, blocking noise and vibration, and insulating property.

The reliable method of blocking noise between floors is known as a double floor structure that forms a room floor with a space completely separated from the walls and floor concrete layer, and this method is 5 to 10 cm wide and 1 to 2 cm thick. Lay the rubber band on the edge of the ready-mixed concrete layer and put a long panel of 1 ~ 2cm wide to fit the length of the floor, and then construct a bubble concrete or plaster mortar layer on the top to make a double bottom structure. .

The present invention relates to a long panel capable of forming a double bottom structure layer, wherein the panel itself has a fiber-fixed plate attached to the styrofoam, while the elasticity of the styrofoam prevents vibration transmission and the airtightness of particles blocks noise. , The high tensile strength of the fiber-fixed plate attached to the upper and lower styrofoam to support the compressive load of the upper plaster mortar layer, and to be able to kill with the mortar mortar layer By omitting the foamed concrete layer and the styrofoam construction layer, it is possible to provide an interlayer noise vibration blocking panel which reduces the interlayer construction thickness and prevents bending breakage due to the compression load of the plaster mortar layer.

Figure 6 is a cross-sectional view showing an embodiment of using the interlayer noise and vibration blocking panel 10 according to the present invention.

According to Figure 6 in the existing construction layer on the ready-mixed concrete layer 40, which is divided between floors 1 to 2 cm, 5 to 10 cm in width of the anti-vibration rubber plate 45 and the interlayer noise and vibration blocking panel according to the present invention ( 10) to first block noise and vibration in the interlayer noise and vibration blocking panel 10 and secondly, a space of 1 to 2 cm formed between the ready-mixed concrete layer 40 and the interlayer noise and vibration blocking panel 10 layer (46). ) To completely block the noise and vibration.

This method is known as a reliable method for noise and vibration blocking due to the double bottom structure method, but general steel or wood panels are not insulated so that the heat of heating is transferred to the bottom, and the load of the upper plastering mortar layer 44 when manufactured to a long length is applied. As it is not able to withstand the bending, the plastering mortar layer 44 at the upper part is broken, and the upper layer crack is generated due to thermal expansion as the layer is separated due to lack of bonding with the cement system.

Therefore, the interlayer noise and vibration blocking panel 10 according to the present invention prevents thermal diffusion to the lower side with the thermal insulation of the styrofoam 20 inside, and the high tensile strength of the fiber solidified plates 22a and 22b attached to both sides of the upper plastering Since it can withstand the load of the mortar layer 44, the heating pipe 43 can be directly provided on the interlayer noise and vibration blocking panel 10, and the plaster mortar layer 44 can be constructed on the upper surface of the foam concrete layer 42. Not only can it be omitted, but also the paste of the plastering mortar layer 44 and the fiber-fixing plate 22b can be reduced, and the interlayer thickness can be reduced and the damage of the upper layer by thermal expansion can be prevented.

Vibration and noise can be reduced, and the interlayer noise and vibration blocking panel 10 has high insulation and tensile strength, and has a noise and vibration blocking ability, so that the load of the plaster mortar layer 44 is omitted even if the foam concrete layer 42, which is an existing interlayer construction, is omitted. There is an effect of preventing breakage due to bending.
