[0002]

[Prior Art]

 In a conventional floor panel, generally, for example, as shown in FIG. 4, the support legs 2 are provided at positions separated from the end of the floor panel 1 by a constant distance. Therefore, when the floor panel 1 is laid on the slab 3 in the room, the floor panel overhangs from the support leg 2 in the peripheral portion of the room 4, and a weak portion is formed at the portion in response to the load indicated by the arrow A. .. On the other hand, the periphery of the room 4 is a place where furniture or the like is placed and strength is required, so it is necessary to take measures to increase the strength against load.

Therefore, as shown in FIG. 5, there is one in which a bundle 5 is set around the room 4, and a joint joist 6 is placed on the bundle 5 to increase the strength (see Japanese Utility Model Publication No. 57-38040). ). Further, as shown in FIG. 6, there is a case in which a sash 6 is fixed to the wall surface 7 of the room 4 by using a stopper 8 (see Japanese Utility Model Laid-Open No. 57-89736). In addition, as shown in FIG. 7, there is one that makes it difficult for the impact sound to be transmitted downstairs. For this, a skirting board 9 is used to escape the compressed air generated under the double floor due to the impact from the peripheral part of the room 4 to the room 4 side (see Japanese Utility Model Laid-Open No. 3-41044).

[0004]

[Problems to be solved by the device]

 By the way, in such a conventional flooring structure as shown in FIGS. 5 and 6, the horizontal level and the floor height are determined by the wall surface 7 and the joist 6 is stopped, but If you make a mistake in the horizontal level, you will have to readjust it, and there will be no place for compressed air due to the shock applied to the floor to escape, which makes the floor impact noise louder than if you let the air into the room. There is a problem that it propagates downstairs. In the one shown in FIG. 7, the underfloor air is allowed to escape to the indoor side, but the space between the joists 6 and the floor floor panel 1 and the slab 3 is hermetically sealed so that the impact noise is actually attenuated. It wasn't something to make them do.

The present invention was made in view of such conventional problems. Even if a plurality of floor panels are provided, the horizontal level of the floor can be easily obtained and the impact sound given to the floor can be attenuated. The purpose of the present invention is to provide a floor structure that reduces the propagation of floor impact sound downstairs.

[0006]

[Means for Solving the Problems]

 As a means for solving the above-mentioned problems, the present invention has a configuration in which a gutter supporting leg is provided in the lower part of the gutter, and the gutter supporting leg is a plate-shaped base placed on the slab, It consists of a support bolt standing upright from the base and a plate-shaped joist support that is screwed to the support bolt and supports the joist. The joist is the joist support of the joist support leg. Support leg mounting portion to be placed on the floor, an insertion portion into which the support bolt of the joist support leg is inserted, a horizontal portion on which the floor panel is placed, and a thickness of the floor panel or more The protruding joist has a more protruding portion, and the joist is placed on the joist support of the joist support leg, and the floor panel is placed on the horizontal part of the joist, and the wall surface of the joist It was decided to attach an elastic body to the part facing to, with a space.

[0007]

[Action]

 Next, the operation of the present invention will be described. The girth joist support legs are erected on a plate-shaped base with bolts placed on the base. The girth joist support is plate-shaped and is screwed into the bolt to support the girth jog from below, but the height of the girth jog support is adjusted by rotating the bolt and girth jog support, and the girth jog support legs are adjusted in height. It will be possible. In addition, there is a space between the plate-shaped base and the bridge joist, and air passes through. The girder joist is a support leg mounting part supported by the girth jog support leg, and is placed on the girth jog receiver of the girder joist support leg, and the insertion part is provided in the center of the girder joist. The support leg bolts are inserted.

The floor panel is placed on the horizontal part of the upper part of the joist, and the total of the height of the protruding part protruding from the horizontal part and the thickness of the floor panel and the floor finishing material placed on it is Since they are almost the same, the upper surface of the protruding portion and the floor floor panel are substantially at the same height. Also, since the elastic body is locked in place on the wall side of the room with the joist, the elastic body absorbs the vibration of the floor floor panel, and between the base of the joist support leg and the joist stand. Since there is a gap in the space, the underfloor air compressed by the impact passes through this gap and the gap between the joist support legs, and then passes through the gap between the wall and the elastic body provided between the joist. It escapes to the inside of the room, and floor impact noise is reduced and propagated downstairs.

【Example】

 The invention will be described below with reference to the drawings. FIG. 1 is a diagram showing the configuration of the present invention. As shown in FIG. 1 and FIG. 2, the overall structure is such that an outer joist 15 is installed around the room 12, and a floor panel having height-adjustable support legs 10 is laid on the slab 13 of the room 12. The floor finishing material 34 etc. are laid on it. The joint joist 15 is placed on the joint joist support leg 14, and the joint joist 15 is continuously formed in the peripheral portion of the room 12. A rubber block 30 as an elastic body is interposed between the joist 15 and the wall surface 26 of the room 12 to leave a gap 32.

The joist support leg 14 includes a base 16 in which an iron plate 37 is attached on a rubber pad 35 to form a plate-like shape, and a bolt 17 having its head placed on the base 16 and placed upward. , And a joist receiver 18 having a substantially U-shaped cross section that is screwed to the bolt 17 and supports the joist 15 from below. At the portion where the sash joist receiver 18 is screwed into the bolt 17, a thick hole 19 is formed by making a round hole in the U-shaped bottom plate of the sash joist receiver 18, and a screw is cut in the round hole. The nut portion 20 is used. Of the U-shaped bottom portion of the sash joist receiver 18, the portion other than the nut portion 20 is the sash joist mounting portion 21 on which the support leg mounting portion 22 of the sash joist 15 is placed. The rubber pad 36 is placed thereon.

The joint joists 15 are provided with support leg mounting portions 22 and bolts 17 of the joist supporting legs 14 that engage with the joist supporting portions 21 provided on the joist receiving portions 18 of the joist supporting legs 14. There is an insertion part 23 to be inserted. The bolt 17 is loosely inserted into the insertion portion 23 so as to have a sufficient gap. On the other hand, on the upper part of the joist 15, a horizontal portion 24 on which the floor panel 11 is placed, and a projection protruding from the horizontal portion 24 by a thickness obtained by adding the thickness of the floor finishing material 34 to the thickness of the plate of the floor panel 11 A section 25 is provided.

Then, a rubber block 30, which is an elastic body, is attached to a portion of the thick joist 15 that faces the wall surface 26 of the chamber 12 with a space therebetween. Here, an uneven portion 27 is formed at an appropriate position on the wall surface 26 side of the room 12 of the outer joist 15, and the rubber block 30 is locked at this portion, and also on a portion of the rubber block 30 facing the uneven portion 27. The structure is such that the uneven portion 28 is provided. Further, as shown in FIG. 3, a rubber block 30 as an elastic body may be mounted in the member of the outer joist 15. However, these uneven portions 27 and 28 may not be provided in some cases.

The diaper joist support leg 14 has a base 16 fixed to a bolt 17 and a head thereof, and a diaper joist receiver 18 has a nut portion 20 screwed to the bolt 17 so that the diaper joist 15 is attached from below. Although supported, the bolt 17 and the nut portion 20 of the gutter support 20 rotate to adjust the height of the gutter support 18, and the gutter mounting portion 21 of the gutter support 18 moves up and down. Accordingly, the thick joist 15 moves up and down, and the height of the thick joist 15 can be adjusted. As a result, the horizontal level of the floor panel 11 can be easily obtained, and the floor can be easily installed.

A gap 31 is always formed between the plate-shaped base 16 and the U-shaped joist support 18 depending on the adjustment position, and air passes through. On the other hand, the support leg mounting portion 22 of the outer joist 15 is engaged with the outer joist mounting portion 21 of the outer joist receiver 18 of the outer joist support leg 14, and in that portion, from the lower side of the outer joist 15 to the insertion portion 23. The bolt 17 of the joist support leg 14 is inserted into the insertion portion 23.

The floor panel 11 is placed on the horizontal portion 24 above the joist 15, and the height of the protruding portion 25 projecting from the horizontal portion 24 and the total thickness of the floor panel 11 and the floor finishing material 34 are approximately the same. Since they are the same, the upper surface of the protruding portion 25 and the floor finishing material 34 are flat. Further, since the rubber blocks 30 are locked at intervals on the wall surface 26 side of the room 12 of the joist 15, the vibrations of the floor panel 11 are absorbed by the rubber blocks 30.

Further, there is a gap 31 as a height adjustment allowance between the base 16 of the joist support leg 14 and the joist support 18, and the joist 15 is placed at an appropriate position on the wall surface 26 side of the room 12. Since the rubber block 30 is locked, there is a gap 32 between the rubber block 30 and the wall joist 15 and the wall surface 26 of the room 12, and the underfloor air compressed by the impact is generated. As shown by the arrow 33, the shock noise passes through the gap 31 of the thick joist support leg 14 and the gap 32 and passes through to the inside of the room 12, and the impact sound is propagated downstairs.

In the above-described embodiment, the diaper joist support 18 of the diaper joist support leg 14 is a U-shaped plate, but the shape is not necessarily limited to this. Further, since the rubber pad 35 is used at the lower end of the base 16 of the joint joist support leg 14, there is sound insulation performance to the downstairs, and the rubber pad 36 and the like is provided between the support leg mounting portion 22 of the joint joist 15 and the joint joist receiver 18. The rubber pads 35 and 36 can be omitted, though the sound insulation is improved by inserting the rubber pads.
