A joist (or joist unit) 113 is provided along the height, and one side of the floor panel 114 is supported thereon. The other edge of the floor panel 114 that is not in contact with the joist is attached to the unit support leg 101 arranged on the base floor 111 at a predetermined pitch in a cantilevered state. The unit support leg 101 and the floor panel 114 are attached via the adhesive sheet 110 or the like attached to the upper surface of the support plate 108 of the unit support leg 101, and the floor panel 114 is pressure-bonded to the adhesive sheet 110 when the floor panel is laid.

際的ではなかった。As described above, in the conventional double floor construction using the unit supporting legs, the floor panel 114 is attached to the upper surface of the supporting plate 108 of the unit supporting leg 101 when the floor panel is laid. The floor panel 114 was fixed to the unit supporting leg 101 by crimping to the 110 and temporarily fixing it, and further after constructing the floor panel 114 in a predetermined area, by nailing the floor panel 114 to the support plate 108. . That is, since the pressure-sensitive adhesive sheet has no durability, it is used only for temporary fixing, and the floor panel and the unit supporting legs are finally fixed by nailing. However,
Even with nailing, repeated use of walking vibration after long-term use causes slack in fixing by nailing,
As a result, floor noise sometimes occurred. When fixing the floor panel and the unit support legs, it is possible to use an adhesive instead of nailing, but applying adhesive one by one on the upper surface of the support plate of the unit support leg only increases the work process. In addition, there is a problem that the operator's hands, clothes, and the surroundings are contaminated with adhesives, which requires subsequent processing and cleaning, resulting in a significant decrease in workability, which is not practical. .

がある。If the support bolts of the unit support legs and the level adjusting nuts are not securely fixed after the floor is constructed, the level adjustment may be misaligned due to the rotation of the support bolts due to repeated walking on the floor or the like, and the screwing portion may be damaged. There are problems such as backlash, falling floor, squeaking of floor, and step difference between floor panels. Therefore, it is necessary to fix the support bolt of the unit support leg and the level adjusting nut with an adhesive or the like. The fixing of the support bolt and the level adjusting nut is performed after the floor level is adjusted. Therefore, when the floor panel and the support plate of the unit support leg are fixed to each other when the floor panel is laid by using the adhesive as described above, the work of applying the adhesive is troublesome and the workability and the workability are low. Is significantly reduced.

In order to do so, it is necessary to fix the unit support leg 101 assembled as described above to the foundation floor 111. Conventionally, this fixing is performed by applying an adhesive to the lower surface of the floor-contacting base 104 of the unit support leg 101 and fixing the adhesive to a predetermined position on the base floor 111, so that the workability of a double floor is improved. However, there was a problem that the construction time was prolonged and the construction cost was increased.
Furthermore, when the floor-contacting base 104 of the unit support leg 101 is fixed to the foundation floor 111 with an adhesive, the support bolts 103 once installed by reaction when the load load during walking etc. There is also a danger that the support bolt will come off the hole in the floor base and collapse due to vertical vibration during an earthquake after the double floor is constructed.

The mesh-like body is provided so as to cover the adhesive flow part except for the holes of the support plate to which is attached.
With such a structure, a plurality of floor panels are laid on the unit support legs arranged at a predetermined pitch on the floor surface of the foundation floor with a predetermined gap so that the edges thereof are supported. Then, when the adhesive is injected from the above-mentioned gap between the adjacent floor panels, the injected adhesive propagates through the separated fibers of the mesh-like body provided on the support plate of the unit support leg and quickly enters the adhesive flow section. Since it diffuses and propagates or penetrates the fibers to diffuse / distribute over the entire mesh body and then solidifies, the bonding area between the support plate and the floor panel increases, and reliable bonding can be achieved. At the same time, the adhesive penetrates into the threaded portion of the support bolt and the level adjusting nut through the adhesive reservoir above the level adjusting nut to bond and fix them.

The fixing between the floor panel and the supporting plate of the unit supporting leg and the locking of the supporting bolt (fixing of the supporting bolt and the level adjusting nut) can be performed at the same time. As a result, even if walking vibration is repeatedly applied to the floor panel, there is no risk of loosening the fixing of the floor panel to the support plate as in the case of fixing with only nails, and it is possible to prevent the support bolts from loosening at the same time. , Can prevent ringing almost permanently. Also, instead of applying the adhesives one by one on the upper surfaces of the support plates of the unit support legs, after laying the floor panels, the adhesives may be injected from the gaps between the unit support leg arrangement portions between the adjacent floor panels. Since it is good, the workability is extremely good, and the problem that the adhesive adheres to the operator's hand, clothes, or the surroundings and stains is greatly alleviated as compared with the coating work. The adhesive reservoir may be formed by expanding the upper part of the level adjusting nut itself, or by chamfering the upper part of the insertion hole of the support plate into which the level adjusting nut is fitted to form the expanded part. However, this may be used as an adhesive reservoir.

With such a configuration, the adhesive flows in between the floor panel and the support plate of the unit support leg and between the level adjusting nut and the hollow support bolt by one-time adhesive injection work. In addition to bonding and fixing the space between them, the hollow support bolt flows down through the central through hole to reach the lower surface of the floor base, and the space between the base and the base floor is also bonded and fixed. Therefore, by one-time adhesive injection work, adhesion / fixation between the floor panel and the support plate and adhesion / fixation between the level adjusting nut and the hollow support bolt, and between the floor contact base and the foundation floor are performed. Bonding and fixing can be performed at the same time, and the workability of injecting the adhesive is significantly improved. Further, when one or a plurality of grooves are formed on the lower surface of the floor-contacting base from the lower end of the inner peripheral surface of the hole to the lower end of the outer-peripheral surface of the floor-contacting base, the lower surface of the floor-contacting base is The flow of adhesive between the floor and the floor surface of the foundation floor is carried out more smoothly and evenly, and the holes in the floor-contacting base and the grooves formed in the lower surface play the role of a cushion.

る。Further, on the lower surface of the floor-contacting base 10, four substantially hemispherical projections 19 are formed between the grooves 16 symmetrically with respect to the axis of the small hole 12. . Note that FIG. 11 shows a cross-sectional view taken along the line BB shown in FIG. By forming such a hemispherical projection 19 or a groove portion 16 protruding in a U-shape, the ground contact area with the foundation floor becomes small, and the load received through the support bolts is dispersed,
By showing moderate elasticity (sinking), floor impact noise,
In particular, the effect of reducing heavy floor impact sound is obtained, and particularly in an apartment house, it is effective in preventing the floor impact sound from propagating downstairs. The heights of the hemispherical projections 19 and the groove portions 16 are preferably about 2 to 4 mm, and are preferably the same height. If the height of the protrusion is too low, the floor impact noise reduction effect is weak, while
If it is too high, the depth of the floor will be large, a stable walking sensation cannot be obtained, and a step may easily occur on the floor, which is not preferable. A long distance from the lower end of the hollow support bolt 20 to the lower surface of the floor-contacting base 10 as in this embodiment is also advantageous for the floor impact noise reduction effect.
