Description

Noise reduction between floors

The present invention relates to an interlayer noise reduction material. More particularly, the present invention relates to an interlayer noise reduction material for reducing interlayer noise by placing a floor finishing layer constructed on a slab between floors of a building with foam material and cement.

Inter-floor noise is noise pollution mainly generated in multi-family houses or apartments. Floor noise refers to the sound of toilet water, floor impact sound, piano sound, audio sound, conversation sound, TV sound, etc. And heavy impact sound (bottom impact sound caused by heavy and soft impact, legal standard less than 50㏈). In the past, single-family-oriented life, problems began to emerge as apartments, such as apartments, became commonplace, and due to the noise of floors due to the characteristics of multi-family homes with multiple layers of walls and floors in between, Arguments can occur. In particular, the floor impact sound (solid transfer sound) generated by direct impact on the concrete surface among floor noises is easily transmitted to neighboring households, and these noises mainly carry children's running sounds and objects from the lower floors upstairs. It is the sound of falling or falling, and the noise between floors, like other noise pollution, has an adverse effect on mental and physical health, which has long been a social issue such as many problems and complaints among neighboring residents.

In order to solve the noise problem between floors, the provisions of the Accreditation and Management Standard for Floor Shock Sound Block Structure for Apartment Houses No. 2016-824, and the Construction Standards for Presidential Decree No. 28628, etc. It proposes housing construction standards related to the prevention of noise between floors. In addition, various research papers for preventing noise between floors (experimental research on the effect of reducing floor impact sound according to the change of slab thickness and stiffness-Kim Tae-hee, performance evaluation for each floor finishing structure considering the floor impact sound of multi-family house) are published and published. have.

In addition, various methods have been invented and proposed to prevent interlayer noise, which is a social problem, and related related art for preventing such interlayer noise is Patent No. 10-1740046.

1 is a view showing the configuration of the floor impact sound prevention material of the prior art Patent No. 10-1740046 associated with the conventional floor impact sound protection material.

Referring to Figure 1, the conventional floor impact sound prevention material is placed on the floor surface of the interlayer slab of the building structure is a gel (Gel) material, the gel sheet to block the floor impact sound belonging to vibration; A rubber sheet laminated on top of the gel sheet and made of a rubber material to block a heavy impact sound belonging to a low frequency; A foam sheet laminated on top of the rubber sheet and made of a foam material to block a light impact sound belonging to a high frequency; And an adhesive sheet laminated between the foam sheet, rubber sheet, and gel sheet, respectively. Through this configuration, it provides a floor shock sound prevention material that can block different noises generated in the life of the apartment house, such as floor shock sound belonging to vibration, heavy shock sound belonging to low frequency, light shock belonging to high frequency.

However, the conventional floor impact sound protection material may be effective in reducing or preventing interlayer noise, but there is a problem in that it is insufficient to reinforce the stiffness of the floor finishing layer on the upper part of the slab.

The floor shock sound, which can be classified into a light shock sound and a heavy shock sound, has an anti-noise effect as the thickness of the medium to which the floor shock sound is transmitted increases and the stiffness increases. Among these, it is known to be mainly related to the stiffness of the medium in the noise transmission path, especially for low frequency noise such as heavy impact sound. In other words, the higher the stiffness, the lower the frequency.

However, the prior art shown above may be effective in preventing high-frequency noise, such as lightweight impact sound, because it is laminated with several panels for noise prevention, but because it is not a structure that is reinforced with floor stiffness, Has the disadvantage of less effective in preventing low noise.

Among the related arts, there are some disclosed structures for absorbing noise by installing a predetermined number of substrates on the panel and covering the bottom of the support with a rubber cover, but even in this case, the supports touching the floor are geometrically. More than three points are in the tool, so most of the support points are not attached to the floor and float at a very small interval.This structure makes the bottom impact sound of the upper slab act as a diaphragm and the bottom finishing layer and slab of the upper slab. The space between them serves as a ring, and the second gap sound is generated by the gap between the slab and the slab upper finishing layer, so that the function of absorbing the floor shock sound is reduced or rather amplified.
