Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor construction method.

In this specification, "sound insulation" means floor impact sound insulation performance.

[0003]

2. Description of the Related Art In middle and high-rise houses, it has been customary to directly attach carpets as a floor surface material to a floor base. However, since carpets are difficult to maintain and require time and labor to replace them, in recent years, there has been a tendency to directly attach a wooden floor material to a floor base instead of the carpets. However, the wooden flooring material has a drawback that it is inferior in habitability because it has a significantly lower sound insulating property than carpets.

In order to solve this problem, a floor material having a foam attached to the entire lower surface of the wooden board may be directly applied to the floor base. Such a floor construction method has already been disclosed in Japanese Utility Model Laid-Open No. 56-394.
No. 5 is disclosed.

[0005]

Regarding the sound insulation, it is said that there is no problem if the sound insulation grade is L-55 or less. In the case of a foam having a foaming ratio taking only sound insulation into consideration, if the thickness is made sufficiently thick until the sound insulation grade reaches L-55, there is no problem in sound insulation. However, if the thickness of the foam is increased until there is no problem with sound insulation,
When heavy objects such as heavy furniture are placed on the floor, the floor will be locally subsided, and there will be another problem that the user feels uncomfortable due to ups and downs every time he walks. The purpose of this invention is
The object of the present invention is to provide a floor construction method that has good sound insulation properties and does not cause problems such as floor subsidence when a heavy object is placed or a bad walking feeling.

[0007] As the buffer member, foamed synthetic resins are common, specific examples of the synthetic resin can be cited polyethylene, the port re <br/> styrene emissions.

As the form of the whole pipe, a meandering pipe having parallel straight pipe portions, a pipe in which both ends of the parallel straight pipe are connected to an inlet side header and an outlet side header, etc. are common. In the case of such a pipe shape, in addition to the parallel groove portions, a groove portion capable of accommodating the entire pipe of the above-described shape is added . The cross-sectional shape of the pipe is usually circular, but is not limited to this,
In the case of a circular shape, its diameter is preferably 3 to 30 mm, particularly preferably 8 to 12 mm. Examples of tubing having a resilient, vinyl chloride, polypropylene, may be mentioned polyethylene emissions, in particular, suitable high density polyethylene.

The interval between the parallel grooves is 10 to 300.
mm, especially 30 to 70 mm is preferable. As a specific example of the liquid, water is generally used, but in addition, ethylene glycol,
It can be exemplified propylene glycol. It is preferable that the liquid does not completely fill the pipe and about 5% of air is present.

Nonwoven fabric or aluminum foil is suitable as a material for the tube escape prevention coating layer. In the former case, the cloth thickness is such that the presence of the tube can be confirmed through the coated surface. In the case of aluminum foil, the shape of the upper end of the tube is transferred to the aluminum foil so that it can be seen, and the presence of the tube can be confirmed by touching it when it is difficult to understand.

As a concrete example of the wooden board, plywood is generally used, but other particles such as particle board, hard board, medium specific gravity fiber board and the like can be mentioned, and the surface thereof is appropriately coated. This makeup is usually made of wood veneer, wood
It is performed by pasting a pattern sheet, a synthetic resin sheet, or cork on the surface or applying a coating .

[Function] Fig. 3 (a) shows the condition when no load is applied to the floor, and Fig. 3 (b) shows the condition when the load is applied, excluding the wooden boards for easy understanding. is there. When the load is applied, the level is slightly lower than when it is not applied, but the upper end of the cushion (2) is placed in the groove (1) almost at the same level as the upper surface of the cushion (2) and the pump is Liquid (4), which is circulated in
As a result, the presence of the pipe (3) to which the internal pressure is applied reduces the amount of deformation of the cushioning member (2) as compared with the case where such a pipe (3) does not exist. This means that the amount of sinking of the floor will decrease when placing heavy objects or walking.

[0013] buffer member (2) itself has in addition to sound insulation effect of the buffering action, a tube having elasticity liquids (4) has been placed
The presence of (3) further improves sound insulation. Because the floor
When a load is applied to the buffer member (2), the upper part of the buffer member (2) sinks, so the elastic pipe (3) inevitably deforms and the liquid inside
(4) Chi wavy, because vibration energy is brought consumption is converted into the wave energy of the liquid. In <br/> it is the mass is greater tubes are compared to empty tube further contains liquid (4) (3), again the floor impact is applied, the liquid having the greater mass (4 ) by the vibration of the cored tube (3), the vibration energy is consumed, resulting sound insulation effect.
