DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a fixing board 4, a heat insulating layer 5, and a sound insulating layer 6 of the floor finishing material 2 are laminated from above on a floor base board 3 provided between the floor finishing material 1 and the floor finishing material 2. It has a multilayer structure.

[0006] The fixing plate 4 is made of wood such as veneer or other materials that can be used for building materials. In the heat insulating layer 5, a thick heat insulating panel 7 made of a porous material is used. The heat insulating panel 7 is a molded plate of foamed plastic such as styrene foam, urethane foam, or polyvinyl chloride, or rock wool or glass wool. Compression molded plate. The sound insulating layer 6 is a thin cushion material 8 having elasticity, and the cushion material 8 is a vibration damping material, a sound absorbing material, and a sound insulating material made of natural rubber or synthetic rubber such as SRC, CR, and NBR. It is a sheet material made of foamed plastic such as styrofoam, urethane foam, or polyvinyl chloride. It is desirable to provide an intervening plate 9 made of the same material as the fixed plate 4 between the heat insulating panel 7 and the cushion material 8, but as shown in FIG.
The intervening plate 9 may not be provided. Therefore, the floor base board 3 according to the present invention is configured to be easily processed by a cutting instrument such as a saw.

In another embodiment, as shown in FIGS. 4 and 5, a plurality of projections 10 are provided on the upper or lower surface of the panel body 7a.
A heat insulating panel 7 in which 10a are regularly arranged is fixed to a fixing plate 4.
, And a heat insulating layer 5 is formed by a space portion 11 formed above or below the panel body 7a by the heat insulating panel 7 and the projections 10, 10a..., And the projections 10, 10a.
The sound insulating layer 6 is formed by the space 11 formed above or below the panel body 7a by a. The panel body
In the floor base board 3 having the heat insulating panel 7 in which the projections 10, 10 a... Are formed on 7 a, an installation plate 18 of the same material as the fixing plate 4 may be provided below the heat insulating panel 7.

Further, as shown in FIG. 6, a plurality of through holes 12, 12a... Are regularly formed in the fixing plate 4, or as shown in FIG. ... may be formed.

The floor substrate 1 may be constructed by the same construction method as in the prior art, and in FIG.
Although the structure constituted by the 14, the joist 15 and the base plate 16 is illustrated, the structure is not limited at all.

Next, the operation of the floor substrate having heat insulation and sound insulation according to the present invention will be described. The floor base board 3 is spread over the floor base 1 constructed in the same manner as the conventional method, and the floor finishing material 2 is spread over the floor base board 3 to construct the floor portion 17.

Living noises generated by walking on the floor portion 17 or falling objects are absorbed by the sound insulation layer 6 and are attenuated to the floor base 1 below and transmitted to the lower floor. The transmitted sound becomes smaller. Also, by forming the through holes 12, 12a,... In the fixing plate 4, the sound absorbing effect is improved.
The formation of 13a prevents the floor base board 3 from warping.

[0012]

In summary, the present invention relates to an underfloor board 3 provided between the underfloor 1 and the finishing material 2, wherein a heat insulating layer 5 and a sound insulating layer 6 below a fixing plate 4 of the finishing material 2 are formed. At the same time, the heat insulating layer 5 was made of a heat insulating panel 7 made of a porous material, and the sound insulating layer 6 was made of a cushion material 8, so that the floor base board 3 had a sound insulating function and a heat insulating function simply by being spread over the floor base 1. Since the floor portion 17 can be constructed, such work can be simplified.

Further, the heat insulating panel 7 and the cushioning material 8 are relatively soft, and the strength of the floor base board 3 is slightly lower. However, since the intervening plate 9 is provided between the heat insulating panel 7 and the cushioning material 8, the floor base board is provided. 3 itself can be reinforced, and the heat insulating panel 7 and the cushioning material 8 cannot be bonded to each other depending on the material. It can be fixed securely.

The heat insulating layer 5 is provided with at least one of the upper and lower portions of the panel main body 7a by the heat insulating panel 7 having a plurality of projections 10, 10a. , And the sound insulation layer 6 is composed of the projections 10, 10a,... And the space 11, which is formed in at least one of the panel bodies 7a by the projections 10, 10a,. Has a two-layer structure, so that the heat insulating effect can be further improved.

Further, a plurality of through holes 12, 12a...
Is provided, the sound absorbing effect of the floor base board 3 can be further improved, and a plurality of grooves 13, 13a... Are provided on the lower surface of the upper fixing plate 4, so that the adhesive material is As a result, it is possible to improve the integration of the fixing plate 4 and the heat insulating panel 7 and offset the floor base board 3 whose both ends are easily lowered and warped by the fixing plate 4 which is easily warped to the opposite side. The practical effect is extremely large, for example, the floor base board 3 can be maintained in a flat plate shape.
