Description

Floor Construction Method for Reducing Noise Between Floors

The present invention relates to a floor construction method for reducing inter-floor noise that can effectively attenuate floor impact and noise.

In recent years, apartment houses, which are mainly used as residential spaces, and apartment houses such as tenement houses, are experiencing various problems due to the noise problem between floors. .

Playing an instrument such as a piano or sound from audio or television is classified as air transmission noise, and noise generated by dropping or running an object can be classified as impact noise.

Since the Korean apartment house is a wall-type structure in which the wall supports the load, it is characterized by the fact that solid noise, that is, the structure noise, is transmitted along the wall and the floor. Most of them are blocked by the slab structure, but when an impact or vibration is directly applied to the floor by a person's walking or dropping an object from the upper floor, it is converted into a solid propagation sound and is hardly attenuated. It has the characteristic of radiating into adjacent generations.

The floor impact sound is roughly divided into a light impact sound that generates a lot of high-frequency components, such as the sound of a bowl or object falling, and a chair moving sound, and a heavy impact sound that generates a lot of low-frequency components, such as an adult walking or jumping children.

In order to block various types of inter-floor noise as described above, conventionally, impact-resistant members such as carpets or mats were laid on the floor to block or reduce noise. There is, in the prior art, the buffer layer is made of a single-layer structure, there was a problem that the effect of reducing the floor impact sound is insignificant.

In order to solve the above problems, a method of laying a synthetic resin mat having a foam layer first and then pouring a mortar has been proposed when constructing the floor of a building, but even in this case, a phenomenon in which the sound of solid propagation is transmitted on the mat occurs. , there was a problem in that the cost of floor construction increased because synthetic resin mats are expensive.
