A male screw portion 42 is engraved on the outer periphery of the lower support member 41. A base 43 formed in a substantially square plate shape is arranged and fixed to the lower end of the lower support member 41 so as to be orthogonal to the cylinder center. The lower support member 41 is vertically erected on the floor surface by placing the base 43 on the floor surface, and fixed to the floor surface by an appropriate means (not shown) such as an anchor bolt. It is supposed to be done.

On the other hand, the upper support member 45 paired with the lower support member 41 has an inner diameter substantially equal to the outer diameter of the lower support member 41 and an inner diameter of the space 18 formed by the four floor panel groups 10. Is formed into a thin-walled cylindrical shape having an outer diameter of a small diameter, and an internal thread portion 46 that is screwed into the external thread portion 42 of the lower support member 41 is engraved on the inner periphery thereof. The upper support member 45 and the lower support member 41 are screwed together via the male screw portion 41 and the female screw portion 46 so as to be movable back and forth in the cylinder center direction.

The lock plate 47 for fixing the upper support member 45 to the lower support member 41 is disposed on the lower side of the upper support member 45 in the male screw portion 42 of the lower support member 41, and moves back and forth in the axial direction. It is screwed freely. The lock plate 47 is formed in a thin plate shape having a substantially oval shape in a plan view, and handle portions 48 are formed by both ends of the oval shape. That is, the handle portion 48 is extended to the outside of the outer peripheral edge of the receiving plate 49, which will be described later, so that the rotation operation of the lock plate 47 can be performed without being obstructed by the receiving plate 49. Further, a rib 47a is integrally provided on the outer peripheral edge of the lock plate 47 by bending the outer peripheral edge portion of the lock plate 47 at a right angle with a constant width and integrally projecting the rib 47a. The rigidity of is improved.

In this embodiment, the receiving plate 49 is formed integrally with the upper end of the upper support member 45. That is, the receiving plate 49 is deep-drawn together with the upper support member 45 to be integrally formed with the upper end portion of the upper support member 45 in a radially outward flange shape. The receiving plate 49 is formed in a circular ring shape having an inner diameter equal to the outer diameter of the upper support member 45 and an outer diameter larger than the space 18 formed by the group of four floor panels 10. That is, the receiving plate 49 is configured to contact the lower surface of the annular ridge 17 formed by the lower plate 12 of the floor panel 10 at the outer peripheral portion of the upper surface thereof and receive the load of the floor panel 10. .

A cushion 50 is laid on the upper surface of the receiving plate 49. The cushion 50 is made of rubber or resin and is integrally molded into a circular ring shape that is substantially the same as the receiving plate 49. Around the outer periphery of the cushion 50, a plurality of locking claws 51 are provided at equal intervals in the circumferential direction and project downward, and each locking claw 51 extends over the outer periphery of the receiving plate 49. The cushion 50 is fixed to the receiving plate 49 by being respectively locked to the edge portions of the lower surface thereof. Further, four partition walls 52 are provided on the upper surface of the cushion 50, and are integrally projected upward in the circumferential direction at intervals of 90 degrees. Each partition wall portion 52 is formed in an arc shape having a semicircular shape in a plan view, and is arranged so that its bent portion side is an inner side, and the annular projections 17 and 17 of the adjacent floor panels 10 and 10 are arranged. It is sandwiched between opposing side walls.

Next, a method of laying the floor panel 10 will be described. First, a plurality of floor panel supporting devices 40 according to the present invention are arranged at predetermined positions on the floor surface 53 corresponding to the corners of the floor panel group to be laid, respectively. Installed. That is, the lower support member 41 of the support device 40 for each floor panel is vertically erected on the floor surface by mounting the base 43 on the floor surface, and the base 43 is fixed by anchor bolts or the like. As a result, it is fixed to the floor surface 53.

Then, by rotating the upper support member 45, the position with respect to the lower support member 41 is changed and adjusted, and the height position of the receiving plate 49 is adjusted to a predetermined height that is selected in advance. To be done. After confirming that the height position of the receiving plate 49 has been adjusted to a predetermined height, the lock plate 47 is rotated and pressed against the lower end surface of the upper support member 45. When the lock plate 47 is pressed against the upper support member 45, the upper support member 45 and the lock plate 47 have a so-called double nut relationship with the male screw portion 42 of the lower support member 41. 45 is fixed to the lower support member 41 by the lock plate 47. Further, when the lock plate 47 is rotated, the handle portion 48 of the lock plate 47 is extended to the outside of the outer peripheral edge of the receiving plate 49, so that the rotating operation of the lock plate 47 is not hindered by the receiving plate 49. . Further, since the rib 47a is formed on the outer peripheral edge of the lock plate 47, the rigidity of the lock operation of the lower support member 41 of the upper support member 45 does not become insufficient.

Thereafter, four floor panels 10 are provided for each floor panel support device 40 on the support devices 40 for each floor panel arranged at the positions corresponding to the four corners of each floor panel 10. The corner portions of the supporting device 40 of the supporting device 40 are placed in abutting relation with each other, and are sequentially arranged and laid. That is, when four floor panels 10 are opposed to the floor panel support device 40 from above and four corners are butted with a phase difference of 90 degrees, the four corners A circular recess 14 and a cavity 18 containing it are formed. Then, when the four floor panels 10 are lowered onto the receiving plates 49 of the floor panel supporting device 40, the lower surface of the annular ridge 17 formed by the lower plate 12 of the four floor panels 10 supports the floor panels. The device 40 is placed on the upper surface of the receiving plate 49 via the cushion 50.

The lower surfaces of the annular ridges 17 on the lower plates 12 of the four floor panels 10 in the state of being placed on the receiving plate 49 are located at 90 degrees with respect to each other around the center line of the floor panel supporting device 40. They are aligned in a ring shape with a phase difference, and are in a state of forming voids 18. Relatively, a portion of the upper support member 45 of the floor panel support device 40 above the receiving plate 49 is located in the space 18 surrounded by the annular ridges 17 of the lower plate 12 of the four floor panels 10. It is in the inserted state. That is, the upper end portion of the support device 40 for the floor panel overlaps with a part of the thickness of the floor panel 10. Therefore, the support device 40 for the floor panel supports the floor panel 10 at a lower position by the amount of the overlapping.

As described above, after the four floor panels 10 are supported by the floor panel support device 40, the circular recesses 14 formed at the corners of the four floor panels 10 serve as connecting member mounting portions. The connecting member 21 of the connecting device 20 for the floor panel is inserted therein and mounted. First, when the connecting member 21 is inserted into the circular concave portion 14 in the aligned state, the four horizontal fixing convex portions 23 on the connecting member side are respectively inserted in the horizontal fixing concave portions 16 on the floor panel side. In addition to being fitted, the four holding members 24 are inserted into the insertion opening 15 from above. Further, the protrusion 27 protruding from the outer periphery of the connecting member main body 22 is fitted into one of the slits 19 formed in the corner portions of the adjacent floor panels 10, 10. By fitting the projection 27 and the slit 19, the connecting member 21 is in a state in which it is prevented from rotating with respect to the circular recess 14.

Subsequently, when the push-spreading member 30 is inserted into the insertion hole 26 of the connecting member 21, the four holding members 24 are pushed outward by the outer circumference of the main body 31 in the radial direction, so that the respective engaging claws are pushed. 25 are engaged with the lower surface side of the opening edge of the insertion opening 15 formed in the bottom wall of the circular recess 14 of the floor panel 10. At this time, the retaining portion 32 projectingly provided at the front end of the push-spreading member 30 is pushed down below the engaging claw 25 to be accommodated in the accommodation hole 44 of the lower support member 41. Then, the engagement of the engagement claws 25 with the insertion holes 15 prevents the connecting member 21 from coming out upward from the circular recess 14 serving as the connecting member mounting portion on the floor panel 10 side. Further, since the tip end portion of each holding member 24 meshes with the thread groove of the male screw portion 35 of the push-expanding member 30 inserted into the insertion hole 26, the push-expanding member 30 is accidentally pulled upward from the insert hole 26. Exiting is prevented.

On the other hand, by inserting the horizontal fixing projections 23 on the connecting member side into the four horizontal fixing recesses 16 on the floor panel side, the floor panels 10 are separated from each other in the horizontal direction. Is prevented. Due to the fixing action of the horizontal fixing member 23, the four floor panels 10 are reliably connected to each other via the connecting member 21, so that the four floor panels 10 are displaced from each other in the horizontal direction. It is possible to reliably prevent such a condition.

According to the embodiment described above, since the lock plate 47 for fixing the upper support member 45 to the lower support member 41 is formed in a thin plate shape, the thickness of the lock plate 47 is thin. The adjustable range of the support height can be ensured to a large extent, and as a result, the double floor can be constructed low.

Further, since the handle portion 48 is provided so as to project from the lock plate 47, engagement work of a tool such as a spanner can be omitted when fastening the lock plate 47, and the support device 40 for the floor panel 40. Even if it is installed near the floor, the fastening work can be performed relatively easily.

It is needless to say that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the invention.

For example, the shape and structure of the lock plate and the handle portion thereof are not limited to those of the above-described embodiment, and the shape and structure of high lock performance and operability are provided within the range where the above-mentioned effects can be exhibited. It can be modified appropriately.

Further, the shapes and structures of the lower support member and the upper support member are not limited to the configurations as in the above-described embodiment, but can be appropriately modified.
