It is about.

(Prior Art and Problems) In a building that houses computers, office automation equipment, etc., to secure wiring and piping required by these equipment under the floor and to secure an airflow space for air conditioning. The free access floor is used for this. A conventional technique of this type will be described with reference to FIGS. 10 and 11. 10th
FIG. 11 is a side view of an example of a conventional free access floor supporting leg used in a machine room accommodating a computer or the like, and FIG. 11 is an example of a conventional free access floor supporting leg used in an office room accommodating an OA device or the like. It is a side view. In the conventional technology, the support bolt that defines the floor height is fixed to the bottom plate, so the floor height of the free access floor is
It was regulated by the height of the original support leg.

As shown in FIG. 10, a free access floor used in a machine room accommodating a computer or the like is constructed by laying a plurality of floor boards 1 on support legs 2. The support leg 2 includes a support bolt 3 with a bottom plate 4, a support block 5, an adjusting nut 6, and a fixing screw 7.

In order to prevent lateral displacement of the floor plate 1 and to secure the earthquake resistance of the free access floor, the lower ends of the support legs 2 are fixed to the body floor surface 8 of the building by means such as adhesion.

FIG. 11 shows a case of a free access floor having a low floor height used in an office or the like accommodating OA equipment, but shows that the floor board 1 is supported by supporting legs 9 having a low height. ing. The low-height support leg 9 comprises a short support bolt 10 with a bottom plate 4, a bearing block 5, and a fixing screw 7.

FIGS. 10 and 11 show examples of the support leg in which the bottom plate and the support bolt are integrated.
In some cases, such as 0-115327 or No. 60-46733, the bottom plate and the support bolt are constructed as separate parts.

However, No. 60-115327 and No. 60-4

(Fig.) Female screw diameter, and in the case of SAIkai Sho 60-46733, when only the support leg with a diameter that matches the diameter of the post insertion hole of the lower leveler (Figs. 3 and 4) can be used, and the floor height is lowered However, in order to increase the floor height, the screw rod of No. 60-115327 or No.
If it is necessary to increase the diameter of the column of No. 46733, it is necessary to replace the leg seat and adjusting table of No. 60-115327, and the lower leveler and the upper leveler of No. 60-47373. There was a problem of becoming.

In addition, since the leg seat and the screw rod in Jitsukai Sho 60-115327 and the lower leveler and the strut in Jitsukai Sho 60-46733 are fixed with a set screw and a strut fixing male screw, respectively, a screw rod, There was structural concern about the columns coming off.

In this way, since the floor height of the free access floor used is different between the office room accommodating OA equipment and the machine room accommodating computers, etc., and the supporting legs do not have the function of changing the height, the usage of the room If the floor height changes and the required floor height changes, it is necessary to remove the existing support legs that are fixed to the building's body floor surface by adhesion, etc., and replace them with new support legs. did. Further, due to the construction work, noise and dust are generated, which requires countermeasures, and repairs may be required to restore the smoothness of the building floor surface.

(Purpose of the Invention) In view of the above problems, the present invention has a support leg with a bottom plate,
Alternatively, it is an object of the present invention to provide a supporting leg with a required bottom plate by removing the bottom plate, or a supporting leg capable of easily changing the floor height without the work of replacing it with the bottom plate.

(Means for Solving Problems) In order to solve the above problems and achieve the object, the present invention provides a bottom plate with a leveling material having a bolt portion at an upper portion and a female thread portion at a lower portion. By mating with a male screw, a part with the same function as a conventional support bolt with a bottom plate is formed, and the floor height of the free access floor can be changed by replacing the adjusting material with a different length. The main feature is that they are trained.

With the conventional technology, it is possible to replace the leveling material that has the same function as the support bolt of the support leg that regulates the height, and change the height of this leveling material to increase the floor height of the free access floor. Different from the fact that it can be changed, the floor height of the free access floor can be changed according to the present invention.
Alternatively, it is possible to remove the bottom plate and perform it without the work of replacing it with the required support legs with the bottom plate or the bottom plate.

In contrast to the conventional technique, in the present invention, by making the external thread of the seat plate with external thread have sufficient strength,
Even if the floor height is increased by replacing the diameter of the steel pipe and the thickness of the steel plate in the general conditioner, and replacing the long nut in the case of short conditioner with one that has no problem in strength, No. 60-47733, No. 60-1
It is possible to easily cope with this without removing the bottom plater of No. 15327 or the seat plate with the male screw corresponding to the leg seat.

As described above, in the present invention, the fine adjusting function is limited to only the upper part of the adjusting material, but the adjusting material is not fixed to the bottom plate by welding, adhesive, etc. Since it is fixed by being screwed onto the bottom plate, it is possible to realize a double floor with a low floor height, which is significantly superior in structural safety to the conventional technology.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 to 9. Fig. 1 is a side view of the free access floor support leg assembled with the upholstery material 11, and Fig. 2 is the short upholstery material 18.
Side view of a free access floor support leg with a low floor height assembled together with Fig. 3, Fig. 3 is a side view of the upholstery material 11, Fig. 4 is a sectional view of the upholstery material 11, and Fig. 5 is a short upholstery material. 18 side view, 6th
FIG. 7 is a sectional view of the leveling material 18, FIG. 7 is a side view showing the bottom plate 16 with external threads 17, FIG. 8 is its sectional view, and FIG. 9 is its plan view.

The upholstery material 11 and the short upholstery material 18 enable the floor height of the free access floor to be changed, and have the configurations shown in FIGS. 3 to 6. The upholstery material 11 is shown in FIG.
As shown in FIG. 4, the bolt portion 12 is connected to the upper portion of the steel pipe 14 through the steel plate 13, and the female screw portion is incorporated in the lower portion of the steel pipe 14 to form the structure. The short leveling material 18 is formed by screwing a bolt portion 19 into a long nut 20 and fixing it with a fixing screw 7. The bolt portion on the upper portion of the upholstery material receives the bearing block 5.

As shown in FIG. 7, FIG. 8 and FIG. 9, as the base portion of the support leg, the central male screw 17 is fixed and the bottom plate 16 with the screw 17 is formed.

FIG. 1 shows a case where a free access floor support leg is formed by using the upholstery material 11. When the floor height is required for the machine room that initially accommodates computers, etc., the support legs for the free access floor are the bottom plate 16 with male threads 17 and the adjusting material.
It is composed of 11, bearing block 5, adjusting nut 6, and fixing screw 7. The work to install this is the bottom plate 16 with male thread 17
Is fixed to the building floor 8 of the building, and the male screw 17 and the female screw 15
The leveling material 11 is screwed together with, and the free access floor floor level is brought out by the adjusting nut 6 in which the bolt part 12 of the leveling material 11 is screwed, and the bearing block 5 is connected to the bolt part 12 and the fixing screw 7 is used. Fix and complete by placing the floor plate on the bearing block 5.

When the purpose of the room is changed to an office, etc., if necessary, and if the floor height is not needed for the purpose of increasing the ceiling height, remove the bearing block 5 and adjust the height. Remove the material 11 from the male thread 17 of the bottom plate 16 with the male thread 17,
Is screwed onto the male screw 17 of the bottom plate 16 with the male screw 17, and the height of the free access floor is adjusted by the adjusting nut 6 in which the bolt 19 of the short height adjusting material 18 is screwed, and then the height is shortened. Construction is completed by connecting the bearing block 5 to the leveling material 18, fixing it with the fixing screw 7, and mounting the floor plate on the bearing block 5. For such simple construction, for example, in the case of a support bolt with a bottom plate, or a structure in which a pedestal has an insertion part and a pillar is inserted therein, it is necessary to remove and replace the support bolt with a bottom plate, the leg seat, and the leg plate. It cannot be achieved because there is

On the contrary, when the floor height is increased to cope with a large amount of cables or to secure an air-conditioning space for air conditioning, the bearing block 5 is removed and the short leveling material 18 is screwed.
Remove the bottom plate 16 with 17 from the male thread 17 and attach the height adjusting material 11 to the male thread 17
The height of the free access floor is adjusted by the adjusting nut 6 that is screwed into the male thread 17 of the bottom plate 16 and is screwed into the bolt portion 12 of the height adjusting material 11, and then the height adjusting material 11 is adjusted again. The work is completed by connecting the bearing block 5, fixing it with the fixing screw 7, and mounting the floor plate.

As is clear from this work content, compared to the conventional technology, the change in floor height of the free access floor is due to the support legs with the bottom plate, or with the bottom plate removed, the required support legs with the bottom plate,
Alternatively, it can be easily carried out by exchanging upholstery materials of different lengths while fixing the male-threaded bottom plate to the building's body floor surface without the work of replacing the bottom plate. A particularly simple structure for the male threaded bottom plate enables a wide range of height adjustments that are difficult to achieve with other structures.Because the bottom of the upholstery material and the male thread with the bottom plate are screwed together, It is an advantage of the present invention that it is possible to obtain a low floor height while guaranteeing structural safety that is significantly superior to that of the above structure.

(Effects of the Invention) As described above, the present invention can improve the floor height of the free access floor as compared with the conventional technology without removing the existing support legs or installing new support legs. Can be easily changed by replacing the upholstery material of different length with the bottom plate with the external thread fixed to the building floor surface.

As described above, according to the present invention, since the upholstery material is fixed to the bottom plate by being screwed, it is possible to form a safe support leg, and the threaded rod required in the prior art. The lower nut that fixes the position of is unnecessary, and it has become possible to realize a double floor with a floor height that is as low as the height of the nut. This is a great effect due to the screws provided on the bottom plate.
