Description

FIELD OF THE INVENTION [0001] The present invention relates to a floor finishing module,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightweight impact sound reduction floor finishing module, and is a technology applied to shipbuilding marine and building fields. More particularly, the present invention relates to a bottom finishing module capable of reducing a light weight impact sound through a bottom portion that finishes the surface at the top portion and a damping portion that reduces vibration, which is installed on the integrated housing type and cushion bottom structure.

Noise and vibration transmitted from upper to lower floors in apartment houses such as cabins and apartments are always an important problem, and the biggest problem is that the impact on the upper floor is transmitted through the ceiling or wall of the lower floor It can be called floor impact sound.

The floor impact sound means that the floor slab vibrates due to impacts caused by people walking, dropping, moving, etc., on the floor, and the vibration is reflected as negative sound in the air.

This floor impact sound is a sound generated by light weight and has a large amount of high frequency components. It has a long and low duration due to light impact noise (high frequency noise) caused by scratching the upper floor and noise generated by heavy objects It is characterized by frequency components and can be divided into heavy impact sound (low frequency noise) caused by children running or walking on the upper floor.

The Ministry of Land, Transport and Maritime Affairs revised the "Housing Construction Standards, etc." in 2017 to strengthen the design standards to meet the light floor impact noise of less than 58dB and the heavy floor impact sound of less than 50dB. Since strengthening the standard for floor impact sound has a great influence on the construction time, it is necessary to prevent the increase of cost due to the strengthening of the floor impact sound and to solve the interlayer noise problem.

In the case of the integrated floor structure, it is effective to reduce the heavy impact sound, but it is somewhat insufficient to reduce the light impact sound. In addition, due to the steel structure, due to the nature of the ship and plant floor structure, the reduction of lightweight impact sound is insufficient.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the related art as described above, and it is an object of the present invention to provide a floor structure for finishing a surface at an uppermost portion of a building floor structure, a damping portion for reducing vibration, And a bottom finishing module for maximizing the effect of lightweight impact sound reduction by filling grooves in the upper part of the fibreboard and filling urethane foam.

In order to accomplish the above object, a floor finishing module for finishing a floor structure of a building according to the technical idea of the present invention and reducing a light weight impact sound includes a surface layer 130 exposed to the outside, a floor layer 150 forming a floor, A first elastic layer 230 formed below the bottom part 100 to reduce vibration transmitted from the floor layer 100 and a second elastic layer 230 formed below the first elastic layer 230. [ And a second elastic layer 290 formed under the metal support layer 260 and reducing vibrations transmitted from the upper portion of the metal support layer 260 And a vibration damping unit 200.

The lightweight impact sound reduction floor finishing module according to the present invention includes a bottom portion for finishing the surface and a damping portion for reducing the vibration transmitted from the upper portion, thereby improving the lightweight impact sound reduction efficiency.

Since the damping part is inserted and compressed inside the bottom part which finishes the surface, it is easy to manufacture because there is no bonding step and the float can be prevented when the water touches.

The high-density fiberboard part is provided with grooves, and the urethane foam is filled, thereby maximizing the reduction effect of the lightweight impact sound and increasing the thermal conductivity according to the purpose, thereby securing the Ondol floor structure performance.

It is possible to adjust the thermal conductivity by varying the material of the metal support layer according to the purpose and to adjust the thickness of each layer to improve the space utilization and to include the second elastic part projection which is applied to the lower part of the damping part, Can be maximized.
