Is supported through. Therefore, by adjusting the respective height adjusting means 21, the height at the position of the base portion 23 can be changed to support the upper surface 29a of the main body portion 47 in a horizontal state. Further, by this adjustment, even when the height of the structure 90 varies depending on the location, the upper surface 29a can be made horizontal.

  The height adjusting means 21 includes a support nut 41 and a support bolt 42, and can adjust the length between the main body 47 and the structure 90. The support nut 41 and the support bolt 42 are provided with flange portions 41a and 42a, respectively. The support nut 41 can be screwed onto the support bolt 42, and the distance between the flange portions 41 a and 42 a can be changed by rotating the support bolt 42.

The base portion 23 is a frustum-shaped antivibration rubber, and has a hole 43 in the center.
Then, the support bolts 42 are inserted into the holes 43 of the base part 23 so that the flange part 42 a contacts the upper part of the base part 23. Further, the support nut 41 is inserted into the through hole 48 of the main body portion 47 so that the flange portion 41 a contacts the lower side of the main body portion 47.

  In the floor support structure 1 of the present embodiment, the support member 11 is placed on the structure 90, and the floor panel 10 is placed on and supported by the support member 11. In addition, the protrusion 25 of the support member 11 is inserted into the space 32 below the floor panel 10 so that the floor panel 10 and the support member 11 do not shift. The two adjacent floor panels 10 are connected to each other by being inserted into the space 32 of another adjacent floor panel 10.

  A plurality of the long placement portions 29 of the support member 11 provided in the floor support structure 1 are provided, but the long placement portions 29 are installed on the structure 90 so that the long directions of the respective long placement portions 29 are in the same direction. Has been. Further, the main body portion 47 of the long placement portion 29 has through holes 48 near both ends in the long direction and is supported near both ends, so that the long placement portion 29 can be stably installed. can do.

Moreover, the panel support part 20 of the supporting member 11 is arrange | positioned in the corner | angular vicinity of each floor panel 10, and it can support even if a load is applied to which position. In addition, you may make it support the panel support part 20 of the supporting member 11 by arrange | positioning other than the corner | angular position of the floor panel 10 (side vicinity, center vicinity) as needed.
The panel support unit 20 is installed at a boundary portion between the floor panels 10, and a plurality of floor panels 10 are supported by the same panel support unit 20.

  When the floor panel 10 is installed, the floor panels 10 are installed with a little gap between them, and the support member 11 installed near the corner of the floor panel 10 has the floor panel 10 on the upper side near the center. Not covered. Therefore, after installation of the floor panel 10, if the through hole 48 is not covered by the panel support portion 20, a tool is inserted from above, and the support bolt 42 and the support nut 41 are relatively rotated to adjust the height. can do.

As shown in FIG. 8, the floor support structure 1 is installed by placing the floor panel 10 on the support member 11 while placing the support member 11 on the structure 90. At this time, while adjusting the height of the long placing portion 29, the upper surface 29a of the long placing portion 29 is made horizontal. Then, the panel support unit 20 is placed on the upper surface 29 a of the long placement unit 29 so that the lower surface 20 a of the panel support unit 20 contacts the upper surface 29 a of the long placement unit 29, and is engaged by the groove 40. Then, the square plate portion 24 becomes horizontal, and the protrusion 25 protrudes upward in the vertical direction.
As shown in FIGS. 2 and 8, the long placement portion 29 of the support member 11 has a long direction along any direction of the matrix of the floor panel 10. It is located near the boundary.

  Since the panel support portion 20 is placed on the long placement portion 29, the long placement portion 29 is installed before the panel support portion 20. At this time, all the long placement units 29 may be arranged in the installation region 93 first, and the long placement units 29 can be installed according to the panel support unit 20 to be installed. Moreover, when all the long mounting parts 29 are installed in the installation area | region 93 previously, the panel support part 20 can be installed in order corresponding to the floor panel 10 installed.

  Since the panel support part 20 is arrange | positioned in the boundary of floor panels 10 and the projection part 25 of the panel support part 20 is inserted in the space 32 of each floor panel 10, floor panels 10 can be connected. .
