Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

Floor-to-floor noise prevention floor material manufacturing technology and construction technology

The problem of inter-floor noise is causing a great social crowd. In recent years, there has been a great deal of social wave so that there are several murders due to the interlayer noise between the upper stories.

This problem is caused by the fact that the builder of the building constructs the building by the cheap construction method, but the building material which can reduce the noise between the floor at the time of the construction of the building is not common in the market.

The present invention relates to a floor heating system, which is installed on a floor heating system and installed on an existing floor heating system, or after construction curing, or after construction of a building structure using iron or wood, Floor noise preventing flooring material ".

It should absorb shock vibration caused in daily life, maintain strength even under heavy load or momentary impact, and be easy to handle and install.

1. A hard cushion body 1 made of a PE foam sheet material and a roll sheet or an EVA foam sheet material and a roll sheet on an upper surface of a soft cushion body 2 made of a urethane foam sheet material and a roll sheet or a sponge foam sheet material and a roll sheet, Is pressed with a press using an adhesive or is passed through a roll mill to produce a cushion unit 10a

2. The cushion unit 10a is laminated by two or more layers using an adhesive so that the laminated cushion body 10 is manufactured

3. A laminated adhesive sheet 20 is attached to the upper surface of the laminated cushion body 10 to be printed or fabricated with a film or a cloth or a nonwoven fabric to provide an impact vibration reducing sheet having a laminated structure

       In the impact vibration reducing sheet of the laminated structure of the present invention,

       1. It absorbs the vibrations and noise generated in daily life,

       2. Strength is maintained even under heavy load or momentary impact,

       3. Easy handling and construction.

1: Shock vibration mitigating sheet structure of the laminated structure of the present invention
Fig. 2: Detail view of cross section of shock-absorbing sheet of the laminated structure of the present invention

The present invention relates to an impact vibration reducing sheet having a laminated structure that can be installed on a floor of a building, after installing the ondol and an existing board, or after building concrete is cured, or after construction of the building is made of iron or wood.

Consumer Protection Agency According to the press release on December 16, 2013, the conventional interlayer sound absorbing material is a flooring material or mat installed on the ondol, and most of the products sold on the market are lightweight impact sound (falling of small objects, (Which is represented by the sound of the children pounding, and the duration is long). However, there is a tendency to decrease the impact of the heavy impact sound The effect of mitigation is minimal or insignificant.

However, the impact vibration reducing sheet of the laminated structure of the present invention is superior in the interlayer noise reducing power compared to the conventional interlayer noise reducing material of the same thickness. That is, the shock-absorbing mitigation sheet of the laminated structure of the present invention has a structure in which the hard cushion body 1 of the stacked cushion unit 10a maintains the supporting force (supporting strength) as a floor material, and the soft cushion body 2 Effectively absorbs vibration noise transmitted to the floor concrete.

The reason for adopting this structure is that the thickness of the interlayer noise reducing material should be very thick when it is made of a single material of the soft cushioning body, and it is also inconvenient for walking or cleaning.

BRIEF DESCRIPTION OF THE DRAWINGS Fig.

end. Structure of a shock-absorbing mitigation sheet of a laminated structure

As shown in Fig. 1, in the impact vibration reducing sheet of the laminated structure of the present invention,

The laminated cushion body 10 and the unglazed adhesive sheet 20 in which the hard cushion body 1 and the cushion unit 10a of the elements of the soft cushion body 2 are laminated.

I. Fabrication of Impact Vibration Reduction Sheet of Laminated Structure

As shown in Fig. 2, in the impact vibration reducing sheet having a laminated structure,

1. A hard cushion body 1 made of a PE foam sheet material and a roll sheet or an EVA foam sheet material and a roll sheet on an upper surface of a soft cushion body 2 made of a urethane foam sheet material and a roll sheet or a sponge foam sheet material and a roll sheet, Is pressed with a press using an adhesive or is passed through a roll mill to produce a cushion unit 10a

2. The cushion unit 10a is laminated by two or more layers using an adhesive so that the laminated cushion body 10 is manufactured

3. A microglow pressure sensitive adhesive sheet 20 which is printed or fabricated with a film or a cloth or a nonwoven fabric is attached to the upper surface of the laminated cushion main body 10 to provide an impact vibration reducing sheet having a laminated structure.

* The laminated structure impact vibration reducing sheet may be provided while excluding the grained pressure sensitive adhesive sheet 20 in the structure and manufacturing process of the impact vibration reducing sheet having a laminated structure.
