Description

{Panel for cushioning}

The present invention relates to a shock absorbing panel, and more particularly, to a shock absorbing panel having a shock absorbing protrusion for absorbing an impact applied to a body of a mat, a shock absorbing panel having an upper groove formed therein for reducing vibrations introduced into the body, .

Most of the apartments in our country are constructed of wall structures that show the role of pillars and beams, and the floor structure also has a unique floor heating system called the ondol, which causes load bearing slab, heat insulation to prevent heat loss, lightweight foam concrete, Piping and finishing mortar to form the slab superstructure.

However, in the case of such a house with a wall structure, the problem of interlayer noise is more serious due to the resonance phenomenon transmitted through the wall where the impact vibration applied on the floor is integrated. Recently, as the quality of life has improved, many residents of the apartment complex have been complaining about the performance of the building environment. Especially, the problem of the floor impact noise has become a big complaint to residents.

In order to overcome such inconvenience, the government has introduced the minimum standard for floor impact sound (less than 58dB light weight impact sound and less than 50dB heavy weight impact sound) and implemented it from July 1, 2005.

Accordingly, the standard floor structure has a basic slab thickness of 210 mm, which increases the slab thickness from 30 mm to 75 mm compared to the conventional slab thickness of 135 mm to 180 mm. As a result, It is an economic burden.

Since the thickness of the interlayer can not be made thicker due to the economic burden and the increase of the building load, each household uses the mat by laying it on the floor or the room to reduce the interlayer noise.

Most of the mat is formed of a single-layer foamed synthetic resin or a laminated finish layer on the surface of the foamed synthetic resin layer. In addition, since the effect of blocking perfect noise and vibration is not expected, there is a possibility of disputes between the upper and lower floors Respectively.

On the other hand, there is no separate measure for the interlayer noise due to the resonance phenomenon transmitted through the wall.
