[Prior art]
In recent years, in various buildings such as apartment houses, in order to reduce floor impact sound when constructing a double floor formed by arranging floor materials via a plurality of floor supports on a slab, for example, FIG. As shown in FIG. 6, the floor material 12 which arrange | positioned the several floor support tool 11 provided with the vibration isolator 11c which has cushioning properties on the slab 10, and laminated | stacked several floor member 12A, 12B, 12C on it. I try to arrange it. At this time, the end 12e of the flooring 12 located on the wall 13 side is supported by a support member called joist 14 when installed at a position 2 mm or more away from the wall 13 surface. Thereby, even when heavy objects such as furniture are installed near the wall, the end 12e of the flooring 12 is prevented from sinking. The joist 14 is grounded to the slab 10 via the support column 14a and the pedestal 14b.
The floor support 11 includes a support 11b having a rectangular pedestal 11a for attaching the flooring 12 to the upper part, and a vibration isolation made of rubber or the like that supports the lower part of the support 11b and contacts the surface of the slab 10. It consists of the material 11c and prevents vibration from the floor material 12 such as floor impact sound from being transmitted to the downstairs via the slab 10.
On the other hand, because the joist 14 is usually made of wood and does not have cushioning properties, the vibration (fixed propagation sound) from the flooring 12 is prevented from being transmitted to the downstairs via the wall 13. In order to prevent generation of air resonance sound under the double floor due to the vibration of the flooring 12, an air communication path (gap) 13s of about 2 mm is provided between the flooring 12 and the wall 13. Further, a baseboard 15 is attached along the surface of the wall 13 immediately above the flooring 12 on the surface of the wall 13 that hits the corner of the room. An air communication path (gap) 15 s of about 2 mm communicating with the air communication path 13 s is provided between the tree 15.
If the gaps 13s and 15s are large, it is possible to prevent the propagation of floor vibrations and the generation of air resonance noise, and the sound insulation performance is improved. However, due to the configuration of the room, between the floor material 12 and the wall 13, and Since the size of the gap between the flooring 12 and the skirting board 15 should be as small as possible, at present, the size of the gap is set to about 2 mm as described above.
Further, when the partition wall 16 is provided, a baseboard 17 attached between the outermost floor member 12A and the partition wall 16 and directly above the floor member 12A on the surface of the partition wall 16; A clearance 16s and a clearance 17s of about 2 mm are provided between the floor member 12A.
The partition wall 16 is attached to a ceiling-side runner 16a having a U-shaped cross section on the ceiling 18 side, which is a slab on the upper floor, and a floor-side runner 16b having a U-shaped cross section on the floor material 12 side. And fixing the intermediate column 16c as a base column between the recesses of the runners 16a and 16b, and attaching a wall material 16d such as a gypsum board to the surface of the intermediate column 16c. At this time, in order to improve the sound insulation performance, a cushioning material 16k such as rubber is spread on the bottom of the concave portion of the floor side runner 16b, and the lower end sides of the studs 16c and the wall material 16d are not fixed to the floor side runner 16b. To. Thereby, since the said partition wall 16 will be in the state suspended by the ceiling 18 via the ceiling side runner 16a, propagation of the vibration from an upper floor can be reduced.
[0003]
[Problems to be solved by the invention]
However, the flooring 12 is arranged while the gap between the flooring 12 and the wall 13 or between the flooring 12 and the partition wall 16 is reliably maintained at a predetermined dimension, or the predetermined gap is secured with the flooring 12. However, since the work of attaching the baseboards 15 and 17 requires great caution, not only the workability is bad, but also skill is required, so that the size of the gap varies depending on the worker. In particular, when the baseboards 15 and 17 are attached, the vertical spacing is constant, so that the construction cannot be performed well, and the sound insulation performance is greatly reduced.
Furthermore, when the above-mentioned gap cannot be secured sufficiently, or when the flooring 12 and the baseboards 15 and 17 are in contact with each other, there is a friction sound caused by rubbing the flooring 12 and the baseboards 15 and 17. There were problems such as occurrence.

FIG. 1 is a diagram showing an embodiment of the present invention, in which 10 is a slab that is a foundation floor, 11 is a column 11b having a rectangular base 11a for attaching a flooring 12 to the upper part, A floor support tool 12 comprising a cushioning material 11c having a cushioning property for holding the column 11b on the slab 10 and being grounded to the slab 10, and a flooring 12A as a floor member in order from the floor surface; The floor material formed by laminating particle boards 12C, 13 is a wall, 14 is grounded to the slab 10 via a support column 14a and a base 14b, and is installed at a position 2 mm or more away from the surface of the wall 13 When supporting the end portion 12e of the material 12, a joist 15 is attached to the base 13 on the surface of the wall 13 directly above the flooring 12 along the wall 13, 16 is a partition wall, and 17 is a partition wall 16. Attached skirting 20 is a cylindrical rubber member is a buffer material mounted at predetermined intervals on the bottom surface of the baseboard 15 and the skirting 17.
When constructing the double floor, in order to ensure sound insulation performance, between the wall 13 side end 12e of the flooring 12A located on the outermost surface of the flooring 12 and the wall 13, and the flooring 12A Air communication paths (gap) 13 s and 15 s of about 2 mm are provided between the skirting board 15, and 2 mm between the partition wall 16 and the flooring 12 A and between the flooring 12 A and the skirting board 17. before and after the gap (air communicating passage) 16s, it is necessary to provide the 17s, in this embodiment, as shown in FIG. 2, in advance a plurality of cylindrical rubber bottom surface of the baseboard 15 and the skirting 17 The members 20 are attached at predetermined intervals so that the air communication passages 13s and 15s and the gaps 16s and 17s can be secured at the same time when the baseboard 15 and the baseboard 17 are attached. In addition, the same code | symbol is attached | subjected about the component same as another conventional, and the description is abbreviate | omitted.
[0008]
The height of the cylindrical rubber member 20 is the size of the necessary gap 15s between the flooring 12A and the baseboard 15 or the size of the required gap 17s between the flooring 12A and the baseboard 17. When the cylindrical rubber member 20 is attached to the skirting board 15 and the skirting board 17, the wall 13 or the partition wall 16 side of the cylindrical rubber member 20 is connected to the wall 13 or the above. It is made to attach so that the partition wall 16 may not be touched. Further, since the cylindrical rubber member 20 is arranged at a predetermined interval, a wide gap 20s communicating with the gaps 13s, 15s or the gaps 16s, 17s is provided between the cylindrical rubber members 20, 20. There is. Therefore, when attaching the skirting board 15 and the skirting board 17, the floor member 12 and the wall 13 or the flooring member 12 and the partition wall 16 can be easily attached only by attaching the lower end side of the rubber member 20 to the flooring 12A. A sufficient air communication path can be secured between the two.
That is, the cylindrical rubber member 20 is not only an elastic body, but also has a gap 20s between the rubber members 20 and 20 as described above. In addition, it is hardly transmitted to the partition wall 16, and it is possible to reliably prevent the propagation of floor vibrations and the generation of air resonance noise, thereby greatly improving the sound insulation performance.
[0009]
In this way, in the present embodiment, when applying a double bed, the bottom surface of the baseboard 15 and the skirting 17, previously attached to a previously plurality of cylindrical rubber member 20 at predetermined intervals, After that, since the baseboard 15 and baseboard 17 are attached to the wall 13 and the partition wall 16, the sizes of the gaps 13s, 15s, 16s, and 17s necessary for sound insulation of the double floor are ensured. Can do. Further, since the skirting board 15 and the skirting board 17 can be easily attached, workability can be remarkably improved.
Moreover, since the size of the gaps 13s, 15s, 16s, and 17s is ensured, the floor material 12 and the wall 13 and the partition wall 16 or the floor material 12 and the baseboards 15 and 17 are rubbed. Generation of frictional noise can be prevented.
[0010]
In the above-described embodiment, the cylindrical rubber member 20 is used as the buffer material. However, the present invention is not limited to this, and various shapes such as a prismatic shape can be applied. At this time, as shown in FIG. 3, it is preferable that the cross-sectional shape of the buffer material 21 on the side in contact with the flooring 12 (flooring 12A) is an arc. Thereby, since a contact area with the flooring 12 can be made small, propagation of floor vibration can be further reduced and sound insulation performance can be further improved.
Further, in the above example has described the case where a plurality of cylindrical rubber member 20 is attached at a predetermined interval on the bottom surface of the baseboard 15 and the skirting 17, as shown in FIG. 4 (a), A long rubber member 22 having a plurality of recesses 22s opened on the flooring 12 side, or a long cross-sectional shape on the side in contact with the flooring 12 as shown in FIG. Even if the rubber member 23 is attached to the bottom surfaces of the skirting boards 15 and 17, the same effect can be obtained, and the attachment of the cushioning material (rubber members 22 and 23) becomes easy.
Alternatively, as shown in FIG. 5, a large number of gap portions 24 s communicating with the gap 15 s (gap 17 s) between the floor material 12 and the skirting board 15 (or between the flooring material 12 and the skirting board 17) are formed. by attaching an elongated rubber member 24 which is the bottom surface of the baseboard 15 (skirting 17), a gap portion 24s can be reliably formed without being affected by the unevenness of the surface of the flooring 12 (flooring 12A) . Further, since the deformation of the rubber member 24 due to its own weight from the skirting board 15 and the skirting board 17 is also suppressed, it is possible to reliably form the gap portion 24s.
