[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a support leg structure for a floor panel, and more particularly to a support leg for a floor panel that can reliably fix the support height and can easily adjust the support height.

[0002]

[Prior art]

 For wiring and piping under the floor, there is a double floor as shown in FIG. 7, for example. A plurality of support legs 60 are arranged and fixed at a predetermined interval on the foundation floor, and each floor panel 10 is placed in close contact with the support legs 60 to form a space 10S between the foundation floor and the floor panel 10. To do. Then, wiring and piping are performed in this space 10S.

The height of the support leg 60 can be adjusted by a screw mechanism, and the space 10S having a desired height can be obtained by adjusting the height of the support leg 60. The height adjustment of the support legs 60 is performed when the support legs 60 are arranged and fixed on the foundation floor surface.

That is, after each support leg 60 is arranged, the height of each support leg 60 is adjusted so that the plurality of floor panels 10 are horizontally positioned at a constant level. Here, the foundation floor surface is not necessarily horizontal, and in order to secure a constant level of the floor panel 10, the height of each of the support legs 60 is individually adjusted. After the heights of all the supporting legs 60 are adjusted in this way, the floor panel 10 is laid to complete the double floor.

By the way, when the height is adjusted by the screw mechanism of each support leg 60, it is necessary to fix the height. If the height is not fixed, for example, when the floor panel 10 is laid or wiring work is performed, the operator's foot comes into contact with the support leg 60, and the screw mechanism is twisted to change the height. This is because it will end up.

[First Conventional Example] As a first conventional example for fixing the adjustment height of the support leg 60, there is a double nut mechanism shown in FIG. 8A. The installation plate 61 of the support leg 60 is fixed to the foundation floor 12, and the installation plate 61 is provided with a support column 62 having a thread formed therein.

On the other hand, a panel receiving plate 64 is located above the support legs 60, and the panel receiving plate 64 supports the floor panel 10. A nut 63 is integrally fixed to the panel receiving plate 64, and the nut 63 is screwed into the thread of the support column 62. That is, by rotating the panel receiving plate 64 and the nut 63, the height of the support leg 60 is adjusted to obtain the space 10S having a desired height.

In the first conventional example, a fixing nut 65 is screwed into the support column 62. By strongly tightening the fixing nut 65 toward the nut 63, the panel receiving plate 64 and the nut 63 are prevented from rotating, and the height of the supporting leg 60 is fixed.

[Second Conventional Example] As a mechanism for fixing the adjustment height of the support leg 60, there is a second conventional example shown in FIG. 8B. In the second conventional example, the height is fixed by using a fixing screw 66 provided on the nut 63. The fixing screw 66 is located substantially perpendicular to the central axis of the support column 62, and the nut 63 is screwed into and penetrates the nut 63.

After the panel receiving plate 64 and the nut 63 are rotated to adjust the height, the fixing screw 66 is tightened. As a result, the support column 62 is pressed by the tip of the fixing screw 66, the rotation of the nut 63 is blocked, and the adjustment height of the support leg 60 is fixed.

[Third Conventional Example] Next, a mechanism described in Japanese Utility Model Laid-Open No. 4-27037 is shown in FIG. 9 and FIG. 10 as a third conventional example. 9 is an exploded perspective view, and FIG. 10 is a sectional view. An installation plate 71 for supporting legs 70 is fixed to the foundation floor 12, and the installation plate 71 is provided with a support column 72 having a thread formed therein.

On the other hand, a nut 76 is integrally fixed to the upper portion of the panel receiving portion 74, and the inner surface of the through hole between the nut 76 and the panel receiving portion 74 is fitted to the thread of the support column 72. A thread groove is formed. Then, the panel receiving portion 74 and the nut 76 are screwed into and attached to the support column 72. The height of the support leg 70 is adjusted by rotating the panel receiving portion 74 and the nut 76. The panel receiving portion 74 supports the floor panel 10 via the C intervention member 77.

After the panel receiving portion 74 and the nut 76 are rotated to adjust the height, the fixing height is fixed using the fixing nut 75. The fixing nut 75 has a screw thread formed on the outer surface, and the screw thread fits into a screw groove formed on the inner surface of the through hole between the nut 76 and the panel receiving portion 74. When the fixing nut 75 is fitted and tightly tightened, the fixing nut 75 pressurizes the tip end surface of the support column 72 and prevents the panel receiving portion 74 from rotating.

After fixing the adjustment height of the support leg 70 in this manner, the floor panel 10 is laid. The four corners of the floor panel 10 are cut out in an arc shape (see FIG. 9). Due to the notch, the floor hole 10K is formed so that the upper surface of the support leg 70 is exposed when the floor panels 10 are laid in close contact with each other. After laying the floor panel 10, the floor hole 10K is covered with a fixing plate 78 and fixed with a panel fixing screw 79.

[0015]

[Problems to be solved by the device]

 The conventional floor panel support legs have the following problems. After laying multiple floor panels 10, it may be necessary to readjust the height of the support legs. As described above, the height of each support leg is adjusted to a constant level before the floor panel 10 is laid, but an adjustment error may occur at this time. In such a case, it is necessary to readjust the height of the support legs after laying the floor panel 10.

In particular, when adjusting the height of the support legs, a large number of loaded floor panels 10 may be piled up in one place for the convenience of work, and the weight of the large number of floor panels 10 may be reduced. The base floor surface 12 itself may be bent due to the influence. Even if the height of each supporting leg is adjusted in this state, after the floor panel 10 is laid on the front surface of the floor, the bending of the foundation floor 12 is eliminated, and the level of the floor panel 10 is erroneous. I will end up. Further, after many years of use, the foundation floor 12 may be flexed afterward, and the supporting legs may have to be readjusted.

As described above, the height of the support leg may be readjusted after the floor panel 10 is laid. In the first conventional example shown in FIG. 8A, the fixing nut 65 is tightened against the nut 63 to fix the height of the support leg 60. Therefore, when readjusting the height of the support leg 60, it is necessary to loosen the fixing nut 65. At this time, the floor panel 10 must be removed. There is a problem that it takes time to readjust the height by the work of removing the floor panel 10.

Further, since the panel receiving plate 64 and the fixing nut 65 need to be rotated separately, there is also a problem that the work of height adjustment takes time. For example, when lowering the panel receiving plate 64 from the state shown in FIG. 8A, it is necessary to alternately rotate the fixing nut 65 and the panel receiving plate 64 to a desired position to adjust the height. After the panel receiving plate 64 is positioned at a desired height, the fixing nut 65 is tightened again to fix the panel receiving plate 64. Also in this case, the fixing nut 65 must be rotated and tightened separately from the panel receiving plate 64.

Also in the second conventional example shown in FIG. 8B, like the first conventional example, when readjusting the height of the support leg 70, the floor panel 10 must be removed, which is troublesome. There's a problem. The support leg 70 pressurizes and fixes the support column 62 with the tip of the fixing screw 66. For this reason, there is a disadvantage that the nadir of the support column 62 is crushed and the nut 63 cannot be screwed into this portion. Further, regarding the support leg 70 provided close to the wall surface, when the fixing screw 66 is positioned facing the wall surface, there is a problem that it is difficult to operate the fixing screw 66 and the workability is poor. .

On the other hand, in the third conventional example shown in FIG. 9 and FIG. 10, when readjusting the height of the panel receiving portion 74, it is not necessary to remove the floor panel 10, and there is a problem in this respect. Does not occur. That is, the height can be readjusted by loosening the panel fixing screw 79 with a screwdriver or the like through the floor hole 10K and then rotating the nut 76 and the panel receiving portion 74.

However, also in the third conventional example, as in the first conventional example, it is necessary to rotate the panel fixing screw 79, the nut 76, and the panel receiving portion 74 separately, and the work of height adjustment is performed. There is a problem that it takes time.

Therefore, an object of the present invention is to provide a support leg for a floor panel that does not require removal of the floor panel when readjusting the height of the support leg, and does not require any labor for height adjustment work.

[0023]

【Example】

 [First Embodiment] A plurality of support legs are arranged on the foundation floor at a predetermined interval to support the floor panel 10 (see Fig. 7). Then, a space 10S is formed between the foundation floor surface and the floor panel 10, and wiring and piping are performed in this space 10S.

A first embodiment of a support leg of a floor panel according to the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of a support leg in this embodiment, and FIG. 2 is a side sectional view showing a state in which a floor panel 10 is supported. As shown in FIG. 1, one end of a support bolt 4 is fixed to the installation plate 2 as an installation portion by welding. A thread, which is a bolt thread portion, is formed on the outer periphery of the support bolt 4. On the other hand, on the inner periphery of the bolt hole 6H of the support nut 6, a screw groove that is a nut thread portion that fits into the screw thread of the support bolt 4 is formed below (see FIG. 2). It is attached by screwing it in.

The fixing member 8 is fitted in the bolt hole 6 H of the support nut 6. A screw groove, which is a fixing screw portion that fits into the thread of the support bolt 4, is also formed on the inner circumference of the fixing member 8 and is screwed into and attached to the support bolt 4 (FIG. 2). See). In this embodiment, the fixing member 8 is made of a resin material.

A panel receiving plate 20, which is a panel receiving portion, is connected to an upper end of the support nut 6, and the panel receiving plate 20 supports the floor panel 10. When the support nut 6 and the panel receiving plate 20 are rotated, the support nut 6 and the panel receiving plate 20 move up and down in the directions of arrows 90 and 91 according to the screw mechanism with the support bolt 4. Thereby, the height of the floor panel 10 with respect to the foundation floor surface 12 can be adjusted. The support bolt 4, the support nut 6, the fixing member 8, and the panel receiving plate 20 are integrally assembled at the manufacturing stage.

After arranging a plurality of support legs on the foundation floor surface 12, before placing the floor panel 10 on the support legs, the height of each support leg is set so that the floor panel 10 is positioned horizontally at a certain level. Adjust the height. That is, the support nut 6 is rotated to move the panel receiving plate 20 up and down in the directions of arrows 90 and 91 to obtain a desired height.

After the height of the panel receiving plate 20 is adjusted, the panel receiving plate 20 is fixed to the support bolts 4 so that the adjustment height is not rounded. The height of the panel receiving plate 20 is fixed by tightening the fixing member 8. An operation groove 8G is formed on the upper end surface of the fixing member 8, and a driver or the like is inserted into the operation groove 8G to rotate the fixing member 8.

An operation hole 20H is formed in the panel receiving plate 20 so that the fixing member 8 can be rotated. The fixed member 8 is exposed from the operation hole 20H so as to be rotatable, and a driver or the like is inserted through the operation hole 20H.

FIG. 3 shows a partially enlarged view of FIG. When the fixing member 8 is rotated and lowered in the direction of arrow 91, the working angle portion 8D of the fixing member 8 presses the pressed slope 6M formed in the bolt hole 6H of the support nut 6. As shown in FIG. 3, the slope 6M to be pressed is formed so that the radius L1 from the center line 4C of the nut hole 6H becomes smaller as it goes in the pressing direction (direction of arrow 91) by the fixing member 8. .

The working corner portion 8D of the fixing member 8 presses the pressed slope 6M, so that the upper surface 6a of each thread groove of the support nut 6 is pressed against the thread of the support bolt 4 in the direction of arrow 91. The lower surface 8b of each thread groove of the fixing member 8 is also pressed against the thread of the support bolt 4. That is, the same action as the double nut occurs between the thread of the support bolt 4 and the screw groove of the fixing member 8 and the support nut 6, and the support nut 6 and the panel receiving plate 20 are positioned on the support bolt 4. Fixed. Since the fixing member 8 is made of the resin material as described above, the elastic force of the working angle portion 8D can more reliably apply the pressing force to the pressed slope 6M.

As described above, the adjustment height of the panel receiving plate 20 is fixed, and thereafter, a plurality of floor panels 10 are laid on the panel receiving plate 20 via the interposing plate 21, and as shown in FIG. To complete the floor. Squares of each floor panel 10 are cut out, and the cutouts form panel holes 10H corresponding to the support legs, as shown in FIG.

After laying a plurality of floor panels 10, it may be necessary to readjust the height of the support legs. In this case, first, a driver or the like is inserted into the operation groove 8G of the fixing member 8 through the panel hole 10H and the operation hole 20H, and the fixing member 8 is slightly loosened to release the pressure on the support nut 6.

Then, in this state, the panel receiving plate 20 is rotated to readjust the height. The rotation of the panel receiving plate 20 is operated by holding the panel receiving plate nut 23 which is welded and fixed to the upper portion of the panel receiving plate 20. Here, the rotational resistance due to the friction between the fixing member 8 and the support nut 6 is configured to be larger than the rotational resistance due to the friction between the fixed member 8 and the support bolt 4. Therefore, when the panel receiving plate 20 and the support nut 6 are rotated and moved in the direction of the arrow 90, the fixing member 8 rotates integrally with the support nut 6 due to the rotational resistance due to this friction.

Therefore, when the support member 6 is rotated on the support bolt 4 after the fixation member 8 is slightly loosened to release the pressing force on the support nut 6, the fixation member 8 is rotated by the frictional resistance due to the friction. Rotate with 6. Therefore, it is not necessary to rotate the fixing member 8 and the support nut 6, respectively, and the height of the panel receiving plate 20 with respect to the foundation floor 12 can be easily adjusted.

After readjusting the height of the panel receiving plate 20, the fixing member 8 is retightened to fix the adjusted height.

Second Embodiment FIG. 5 shows a second embodiment of the support leg of the floor panel according to the present invention. In the first embodiment described above, the inner periphery of the fixing member 8 is formed with the thread groove that fits into the thread of the support bolt 4. On the other hand, the fixing member 8 in the present embodiment has a thread groove formed on the outer peripheral surface and is fitted in the thread groove of the support nut.

Also in this embodiment, when the fixing member 8 is tightened, the working corner portion 8 D of the fixing member 8 presses the pressed slope 6 M of the support nut 6. As a result, the support nut 6 and the panel receiving plate 20 are positionally fixed on the support bolt 4. The other structure is similar to that of the first embodiment.

Third Embodiment Next, FIG. 6 shows a fixing member 25 in a third embodiment of the support leg of the floor panel according to the present invention. In each of the above embodiments, the operation groove 8G is formed on the upper end surface of the fixing member 8, and the fixing member 8 is rotated by inserting a driver or the like into the operation groove 8G. On the other hand, the fixing member 25 in the present embodiment is formed in a tubular shape, and the operation bar 25V is attached to the upper portion. When rotating the fixing member 25, the tool 26 is fitted to the operation bar 25V, and the operation bar 25V is held and rotated.

Other Embodiments In each of the above-described embodiments, the fixed member 8 is formed with the working angle portion, and the support nut 6 is formed with the pressed slope. However, as another embodiment, it is also possible to form the pressed slope on the side of the fixing member 8 and form the working corner on the side of the support nut 6.

Further, the present invention is not limited to the structure shown in the above-mentioned embodiment, but the adjustment height of the panel receiving portion can be fixed securely, and the fixing member together with the supporting nut can be fixed by the rotation resistance. Other configurations can be adopted as long as they can rotate integrally.

[0052]

Therefore, after adjusting the height of the panel receiving portion with respect to the foundation floor surface, this adjusted height can be fixed easily and surely.

Further, the rotation resistance between the fixing member and the support nut is greater than the rotation resistance between the fixing member and the support bolt. Therefore, if the support nut is rotated on the support bolt after the fixing member is loosened to release the pressure on the support nut, the rotation resistance causes the fixing member to rotate together with the support nut. Therefore, it is not necessary to rotate the fixing member and the support nut, respectively, and it is possible to easily adjust the height of the panel receiving portion with respect to the foundation floor.

In the support leg of the floor panel according to the second aspect, the rotation resistance due to the friction between the fixing member and the support nut is larger than the rotation resistance due to the friction between the fixing member and the support bolt.

That is, when the support nut is rotated on the support bolt after the fixation member is loosened to release the pressure on the support nut, the rotation resistance caused by the friction causes the fixation member to rotate together with the support nut. Therefore, it is not necessary to rotate the fixing member and the support nut respectively, and it is possible to easily adjust the height of the panel receiving portion with respect to the foundation floor.

In the support leg of the floor panel according to the third aspect, the fixing member is made of a resin material.

That is, when the fixing member is screwed in and tightened to press the support nut, a sufficient pressing force can be applied to the support nut, and the position of the support nut on the support bolt can be further improved.
