To this end, the present invention relates to a flexible foamed article 1 in the form of a sheet in which an insertion hole 2 is formed at a predetermined interval, and an insertion groove 3 is formed in the bottom surface of each insertion hole 2, (10) fixed to the insertion hole (2) of the flexible foam (1) by a fixing means and fixed to the concave groove (3) of the flexible foam (1) And at least one shock absorbing groove 21 is formed on the bottom surface of the soft foam member 1 so that the fastener 10 is inserted into each insertion hole 2 of the flexible foam member 1 to form the flexible foam member 1 The vibration proof rubber 20 is fixed to the fixture 10 so that the vibration proof rubber 20 is positioned in each of the concave grooves 3 located on the bottom face of the flexible foam 1, And the rubber 20 are integrated.
Description
BACKGROUND OF THE
Generally, noise or impact noise is transmitted to the lower floor in the multi-storey apartment building because most of the noise caused by the sound of footsteps generated when moving in the living space of the upper floor resident,
These vibrations and noise are caused by the fact that in the case of a solid solid such as a concrete structure, the transmission is very good. If this is neglected, there is a possibility that a problem arises between the neighbors, so thorough measures are required.
Therefore, it is essential to construct a floor impact sound damping material, which is an interlayer structure for interlayer insulation sound insulation, in order to insulate sound insulation, impact vibration and floor heat energy management in the floor of each floor of a multi - storey apartment building.
A PE nonwoven composite plate excellent in absorbing sound insulating property, heat insulating property, impact absorbing ability and vibration absorbing ability is known in Korean Patent No. 10-0451400 (a polyester nonwoven composite sheet excellent in sound absorption and sound insulation properties and a manufacturing method thereof).
Since the above-mentioned technique is constituted by adhering the PE nonwoven fabric layer on one side or both sides of the rubber sheet material layer, the cost is increased by using the expensive rubber sheet material, and the expensive adhesive device for bonding the PE nonwoven fabric layer to the rubber sheet material layer is required There was a drawback to be made.
In addition, in the domestic public utility model 20-2010-0005135 (floor impact sound reduction material of the apartment house), since the protruding portion and depression portion are continuously formed on the bottom surface of the sound insulating material made of polyurethane, the urethane material cushioning material having the air layer is fixed, In this case, however, the use of expensive urethane-made cushioning material is disadvantageous in that the material cost and the construction cost are excessively consumed.
In addition, in the domestic public utility model 20-2009-0004623 (interlayer sound insulating material for buildings), a foam hole is formed at a predetermined interval in the vibration reduction layer, and an elastic body is injected into the foam hole and a damping layer is attached to the upper surface. This is because the polyurethane elastic body is formed in the vibration reduction layer by injecting the molten polyurethane material into each of the foaming holes of the vibration reduction layer using a separate foam molding machine, and thus the cost of the expensive foam molding machine is increased A separate damping layer must be formed on the upper surface of the vibration reduction layer.
In addition, since the neoprene rubber mount is mounted on the EPS board in the domestic registered utility model 20-0363675 (the insulating floor impact sound reduction material using the EPS board equipped with the neoprene mount having the air layer), the following A problem has occurred.
First, 900 × 900 is equipped with about five neoprene rubber mounts, so there is a limit to support the weight of the floor. As a result, the absorption performance of impact sound is significantly reduced due to deflection over time.
In order to compensate for this structural problem, the existing law established the residual strain test standard (KS F 2873 residual strain measurement method) on the physical properties of the floor impact sound cushioning material. The number of support mounts is 4 or more.
This is a new method to prevent the deterioration of the performance of the product when the product is pushed due to the long-term deflection phenomenon occurring over time when the product is applied only with a plate-shaped product such as styrofoam or a similar soft foam.
Second, a hole is formed in the EPS board, and the neoprene rubber mount is inserted into the hole. Therefore, the neoprene rubber mount can be easily removed from the hole during transportation or installation of the product. Therefore, careful attention is required not to drop the neoprene rubber mount, If the neoprene rubber mount is missing, there is a risk of insufficient construction.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a shock- Thereby facilitating the transportation of the interlayer structure and enabling rapid construction.
Another object of the present invention is to absorb vibration and noise applied to the upper and lower portions of the heat insulating panel.
Another object of the present invention is to make the fixture come into contact with the mortar layer by changing the shape of the fastener fixing the buffer rubber to the heat insulating panel so that the rubber directly acts as a damping when the impact is generated so as to reduce the impact noise.
According to an aspect of the present invention, there is provided a flexible foam comprising: a sheet-shaped flexible foam having insertion holes formed at predetermined intervals, each insertion hole having a concave groove formed thereon; And a vibration proof rubber which is fixed to the insertion hole of the flexible foam by being fixed by fixing means and fixing means and inserted into the insertion hole of the flexible foam, and at least one shock absorbing groove is formed on the bottom face of the flexible foam, And a vibration proof rubber is fixed to the fixture so that the vibration proof rubber is placed in each of the recessed grooves located on the bottom surface of the flexible foam. Impact sound cushioning material is provided.
According to another aspect of the present invention, there is provided a flexible foam comprising: a sheet-like flexible foam having insertion holes formed at predetermined intervals, the insertion holes being formed at the bottom of the insertion holes; And a vibration damping rubber which is fixed by rubber and fixing means and which is located in the concave groove of the flexible foam and at least one shock absorbing groove is formed on the bottom face of the elastic foam, And a pair of vibration damping rubbers are integrated with the flexible foam in the form of sheet so that the lower vibration damping rubber having the shock absorbing grooves is positioned in each of the recessed grooves located at the bottom of the soft foamed body. / RTI >
The present invention has the following advantages over the conventional apparatuses.
First, the anti-vibration rubber that absorbs impact and noise can be integrated into the sheet-shaped flexible foam by the fixture, so that it can be assembled in a large quantity in a factory, so that the construction can be carried out immediately in the field.
Second, since the fixture is made of a hard material such as plastic, it can be attached without sticking to the flexible foam, so that productivity and workability are excellent.
Third, since the impact sound can be absorbed in the upper surface as well as the bottom surface of the flexible foam according to need, it is possible to maximize the effect that the impact sound is transmitted to the lower layer.
Fourth, as plastic is used as a part of the total thickness, the thickness can be thinned, the stability of the upper structure can be maintained for a long time, and the floor impact sound can be reduced.
Fifth, it can be applied to semi-dry type without lightweight bubble layer according to the height adjustment of the fixed or anti-vibration rubber and the height adjustment of the flexible foam.
