Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a support device for a floor panel that is laid on a reference floor such as a concrete floor to form a double floor.

[0002]

[Prior art]

 A double floor to secure a free space below the floor used for arranging cables and ventilation ducts usually has multiple floor panels supported by a supporting device on the reference floor. It is configured by arranging adjacently. By the way, conventionally, as a support device for a floor panel constituting such a double floor, a support bolt with a required length and a locking projection on the upper surface of the support bolt fitted and supported via a tubular body. It is known that the floor panel seat is provided with an adjusting nut member screwed to a support bolt so as to vertically move the floor panel seat while hooking the floor panel seat. In such a supporting device, a support bolt is erected through a base at a position where a plurality of corner portions of a floor panel to be laid on the reference floor surface are assembled, and an adjusting nut member is screwed up and down. At the same time, adjust the height of the floor panel seat properly through the cylinder, and then fix the adjusting nut member and cylinder to the support bolt with the set screw. Then, while engaging the engaging recesses formed on the back surface of the corner of the floor panel with the engaging protrusions, the corners of the floor panel are sequentially placed on the floor panel seats to be adjacent to each other. It is something that can be laid.

[0003]

[Problems to be solved by the device]

 However, since the conventional supporting device has an adjusting nut member that adjusts and supports the floor panel seat at a predetermined height and a tubular body that is fixed to the supporting bolt with a set screw, the adjusting and supporting work is extremely difficult. Not only is it troublesome and time-consuming, but the set screws tend to loosen over time, making their fixation unstable. In addition, the floor panel seat only stabilizes the floor panel by engaging and engaging the engaging projections formed on the upper surface with the engaging recesses on the back surface of the floor panel. It is difficult to expect the support of the floor panel that is always satisfactory, because it easily causes rattling.

The present invention solves all the conventional problems, and not only the height of the floor panel seat can be adjusted very easily and reliably, but also the floor panel can be firmly fastened and supported. It is intended to provide a convenient floor panel support device that can be used.

[0005]

[Means for Solving the Problems]

 That is, the present invention has a supporting bolt 3 with a base 1 having a required length having a screw hole 4 along the axis, and an adjusting table 5 attached to the supporting bolt 3 via a nut member 6 so as to be vertically movable. A substantially cap-shaped floor panel seat 7 having a floor panel engaging protrusion 9 on the upper surface fitted to the adjustment base 5, and a screw of the support bolt 3 inserted through the floor panel seat 7 and the adjustment base 5. It is composed of a fastening bolt member 10 with a floor panel pressing head 11 that can be screwed into the hole 4.

[0006]

[Action]

 The support bolt 3 is erected at a predetermined position on the reference floor surface 18 through the base 1, and the nut member 6 is screwed up and down while the adjustment base 5 is used to adjust and support the floor panel seat 7 at a predetermined height. Excuse me. Then, as shown in FIGS. 2 and 3, while engaging the engaging concave portion 15 of the floor panel 14 with the engaging protrusion 9, the corner portions 16 of the floor panel 14 are sequentially assembled adjacent to each other. Place it on the seat 7. After that, the fastening bolt member 10 is inserted from the upper side through the floor panel seat 7 and the adjustment base 5 and screwed into the screw hole 4 of the support bolt 3, and the head panel 11 is used to install the adjacent bolts of the floor panel 14. The floor panel 14, the floor panel seat 7, and the adjustment base 5 can be integrally fastened together while pressing the corner portion 16 to securely support the floor panel 14.

[0007]

【Example】

 An embodiment of the present invention shown in the drawings will be described below. Reference numeral 1 is a rectangular plate-shaped base having an adhesive escape hole 2 at its periphery, 3 is a support bolt standing upright at the center of the base 1 and having a required length, 4 is an axis of the support bolt 3. It is a screw hole formed along. Reference numeral 5 is a substantially inverted hat-shaped adjustment base that is attached to the support bolt 3 via a nut member 6 so as to be movable up and down, 7 is a substantially circular cap-shaped floor panel seat that is externally fitted to the adjustment base 5. Reference numeral 9 denotes a bolt insertion hole formed in the central portion of the floor panel seat 7, and 9 denotes four engaging projections provided at the outer peripheral edge of the upper surface of the floor panel seat 7 at predetermined intervals. . Reference numeral 10 is a fastening bolt member that is screwed into the screw hole 4 of the support bolt 3 through the bolt insertion hole 8 of the floor panel seat 7. The head portion 11 of the fastening bolt member 10 is a floor panel 14 described later. It is formed in a substantially disk shape so as to be pressed down from above, and a minus groove 12 into which a tip of a coin or a fastening tool is inserted and a hexagonal hole 13 are formed to communicate with each other on the upper surface thereof. In addition, 14 is a rectangular floor panel, 15 is an engaging recess formed on the back surface of each corner 16 of the floor panel 14 so as to correspond to the engaging projection 9 of the floor panel seat 7, and 17 is the same. A notched latching step portion formed in the corner portion 16, and 18 denotes a standard floor surface such as a concrete floor surface.

In the supporting device constructed as described above, first, the base 1 is placed on the reference floor surface 18 where two or four corner portions 16 of the floor panel 14 are adjacently gathered together with an adhesive or a bolt. It is fixed by any fixing means, and the support bolt 3 is erected on the reference floor surface 18. Then, the nut member 6 is screwed up and down along the support bolt 3 to adjust the floor panel seat 7 to a predetermined height by the adjusting base 5. Then, while engaging the engaging recess 9 with the engaging protrusion 9, the corner portion 16 of each floor panel 14 is placed on the floor panel seat 7, and the nut member 6 is attached as necessary. The height of the floor panel 14 is finely adjusted by screwing it up and down. At this time, since the floor panel seat 7 for mounting and supporting the floor panel 14 in the locked state is externally fitted to the adjusting base 5, the rotation adjusting operation of the adjusting base 5 accompanying the screwing of the nut member 6 is performed. It can be done smoothly. When the fine adjustment of the height of the floor panel 14 is completed, the fastening bolt member 10 is inserted from above from the bolt insertion hole 8 of the floor panel seat 7 and the adjustment base 5 and screwed into the screw hole 4 of the support bolt 3. At the same time, the corner portion 16 of the floor panel 14, the floor panel seat 7, and the adjustment table 5 are integrated while holding down the hanging step portions 17 of the corner portions 16 that are adjacently gathered by the head 11. The floor panel 14 is firmly and firmly fixed and supported by being fastened.
