As shown in FIG. 2, the cylindrical member 12 has three molded portions 12a formed at predetermined angles (180 °). Each forming portion 12 a has a predetermined width W in the inner circumferential direction of the tubular member 12 and has a predetermined length L in the axial direction of the tubular member 12. The relationship between the length L and the width W is set so that L> W. Moreover, the screw hole 12h for screwing a set screw is formed in the part which is not press-processed between the two shaping | molding parts 12a and 12a. Then, a set screw 20 for stopping rotation is screwed into the screw hole 12h (see FIG. 1).

The cam slider 32 and the cam driver 33 are supported by the press base 34 so as to be reciprocally movable in the radial direction. In the cam slider 32, a stud bolt 35 extending in the lateral direction is planted, and a nut 37 is screwed to the stud bolt 35 via a washer 36. A compression coil spring 38 is interposed between the washer 36 and the press base 34. Thus, the cam slider 32 is constantly urged radially outward by the urging force of the coil spring 38.

  In the press machine configured as described above, when the cam driver 33 is driven downward, the cam slider 32 and the punch 30 move inward in the radial direction, and a part of the cylindrical member 12 is recessed inward. . At this time, since the die 31 having a predetermined shape is disposed inside the tubular member 12, the tubular member 12 is spaced a predetermined distance inward at three locations spaced apart by a predetermined angle (180 °) in the circumferential direction. A recessed molding portion 12a is formed.

  After forming the three molded portions 12a as described above, as shown in FIG. 4, the molded portions 12a are threaded to form female threads 12s in the respective molded portions 12a. As shown in FIG. 4, since the valley diameter D1 of the female screw 12s is smaller than the inner diameter D2 of the cylindrical member 12 where the molded portion 12a is not formed, a screw is formed at a location other than the molded portion 12a. There is nothing. Then, after forming the female screw 12s on the cylindrical member 12, the flat member 11 and the cylindrical member 12 are integrated by welding to manufacture the floor support base 10.

  The floor support pedestal 10 manufactured as described above is screwed into the screw portion 52 s at the upper end of the support leg 52, and the support leg 52 is tightened by the set screw 20, similarly to the floor support pedestal 53 shown in FIG. 9.

The panel 1 can be mounted on the panel fixing bracket 58 and fixed.

  FIG. 6 is a perspective view showing another embodiment of the floor support base of the present invention. In the floor support base 10 shown in FIG. 6, the planar member 11 and the cylindrical member 12 are formed as an integral member. That is, the flat member 11 and the cylindrical member 12 are integrally molded by making a pilot hole in one flat plate and stretching it into a cylindrical shape, and the molded portion 12a is formed by pressing the molded cylindrical member 12. The floor support base 10 can be manufactured by forming and forming the female screw 12s in the forming portion 12a. Since the floor support base shown in FIG. 6 can be manufactured from one flat plate, the manufacturing cost can be further reduced.

FIG. 7 is a view showing various modifications of the tubular member 12 in the floor support base of the present invention. In the cylindrical member 12 shown to Fig.7 (a), the shaping | molding part 12a is extended over the full length of the height direction of the cylindrical member 12. FIG. In the cylindrical member 12 shown in FIG. 7B, a plurality of molding portions 12a are formed in a row in the vertical direction (three in the example shown in the figure). The molding portions 12a are formed in three rows spaced apart at an equal angle (180 °) in the circumferential direction. In the example shown in FIG. 7C, the cylindrical member 12 is formed by pressing a single flat plate to form the forming portion 12a and then bending the flat plate into a cylindrical shape. And the uneven | corrugated | grooved part 12p, 12p which mutually fits is formed in the butt | matching surface of the both ends of a flat plate, and the butt | matching surface is joined by caulking (coking) in the fitting part of the concavo-convex part 12p, 12p. Yes. In the example shown in FIG. 7D, after the square pipe is cut to form the rectangular tube-shaped cylindrical member 12, the forming portion 12a is formed by pressing.
In the example shown in FIGS. 7A to 7D, the female screw 12s is formed in the molding portion 12a by threading, as in the embodiment shown in FIGS.

The floor support base configured as shown in FIGS. 1 to 7 has the effects listed below.
1) Since the floor support base 10 can be composed of two parts, that is, the planar member 11 and the cylindrical member 12, it is possible to provide a product with a lower cost than conventional products.
2) By pressing the cylindrical member 12 made of a pipe from the outside of the cylindrical member 12, a part of the cylindrical member 12 is dented inward to form a molded part 12a. In this molded part 12a, Since the female screw 12s is formed, the strength is high with respect to the compression / tensile load.
3) The planar member 11 that receives the panel or the like can be subjected to burring to increase the strength of the support surface of the planar member 11.
4) Since the welded portion for joining the planar member 11 and the cylindrical member 12 is not in contact with the support surface that receives the panel or the like, the support surface is not affected by distortion due to welding heat. Processing can be omitted.
5) When forming the molded part 12a on the cylindrical member 12 by press working, the protrusion height of the molded part 12a from the inner peripheral surface of the cylindrical member 12 is adjusted by adjusting the depth of pressing of the punch 30. can do. Therefore, even if the inner diameter of the cylindrical member 12 (the portion where the molding portion 12a is not formed) is constant, the size of the female screw 12s formed on the molding portion 12a can be variously changed. Specifically, when the cylindrical member 12 is formed using a pipe having an inner diameter of 25.4 mm, the protruding height of the molded portion 12a is adjusted even if the inner diameter of the cylindrical member 12 is 25.4 mm. Thus, screws up to about M24, M22, and M20 can be formed. Therefore, one type of commercially available pipe can be used for several types of support legs.
6) Since the inner diameter of the cylindrical member 12 is larger than the diameter of the valley of the female screw 12s, the lower end portion of the cylindrical member 12 is supported when the lower end opening of the cylindrical member 12 is inserted into the screw portion 52s of the support leg 52. It becomes a guide for inserting the screw portion 52s of the leg 52, and the screw portion 52s of the support leg 52 can be easily inserted.
