(6) Because of its excellent strength, buckling does not occur and the floor does not sink.

(Example) Below, v! of the present invention! The 戊 will be explained according to the illustrated embodiment.

FIG. 2(a) shows a floor support Jt. according to the present invention. This is the first example of (^). The floor support metal fittings (^) are installed on a foundation surface (l2) such as a concrete slab.

The mounting plate (1) is a simple rectangular plate with a lower high nut (3) erected almost vertically in the center by caulking or welding, and a female thread is screwed on the inner peripheral surface. Left and right screws (
2) is provided with a threaded rod rotation part (4), such as a hexagonal wrench hook, in the center, and m screws facing in opposite directions are screwed on both sides of the threaded rod rotating part (4). The threaded rod rotation n(4) is
It is not limited to cases such as the above-mentioned spanner hook, but also for left and right screws (
2) A through hole that goes through? It is also possible to rotate the bar by inserting the bar into it, or by rotating the bar from side to side (
2) may be welded at right angles. The support plate (5) is for supporting the floor of a general house or a 7-lead access floor panel (11) directly or through the joists (10), and is a rectangular plate-shaped plate with a hole in the center of the bottom surface. A tall upper nut (6) is fixed by welding or caulking and is hung vertically. The inner peripheral surface of the upper high nut (6) is threaded with a female thread in the opposite direction to the female thread of the lower high nut. Vertical height Natsu}
(3) The female threads in (6) can be full threads, but as shown in Fig. 2, #1 screws are screwed only on the tip side, and the inner periphery of each plate side from this female screw is threaded left and right (2 ) may be formed to be larger than the outer diameter. This portion is defined as a large-diameter hole portion (8).

Then, tighten the left and right screws (2) vertically and vertically (3) (6
), and a large number of floor supports (^) according to the present invention are erected on the foundation surface (12) by gluing at predetermined intervals, and then the left and right threaded rods (2) are attached. Apply a wrench to the rotating part (4) and turn the left and right wands (2) to adjust the height of the free access floor. The support plate (5) moves up and down twice as much as the left and right screws (2) rotate.

Once the height adjustment is complete, turn the fixing nut screwed onto the left and right screws (2) and tighten the left and right screws (2) and the vertical height nut.
) and (8) are fixed. After that, the joists (10) are stretched over the support plate (5) at regular intervals, and then the free access floor panel (11) is laid. Even if, for example, interior components or OA equipment are placed or installed on the general residential floor or free access floor (24) laid in this way, the vertical height will not be high. There is no possibility of buckling.

FIG. 2(b) shows a second embodiment of the present invention in which a lower high nut (3) is inserted into the center hole of the mounting plate, the edge of the center hole is welded to the 7-run part, and This is an example in which the 7-run part of the lower high nut (3) is placed directly on the 7-run part, and the load from the floor is directly borne by the 7-run part, resulting in a structure that does not put much stress on the welded part.

(Effects) In the first aspect of the present invention, a tall nut is erected on the R placing plate placed on the foundation surface, and a tall nut is installed on the lower surface of the support plate for supporting the floor surface. A high nut is installed vertically, internal threads are screwed in opposite directions to each other on the inner periphery of both high nuts, a horizontal bar rotation part is provided in the center part, and male screws are screwed in opposite directions to both ends. Since the screws are threaded into both high nuts, the load from the floor is borne by the strong cylindrical high nut and the cylindrical left and right screws. Unlike the legs, it does not buckle and does not cause the floor surface to become uneven. In addition, since high nuts are used for the legs, they are much stronger than the legs made of sheet metal, so they can be made thinner than the legs made of 2t plates, which prevents them from becoming bulky. It is rice-based and convenient to carry and fill up inventory.

In addition, in claim (2), the inner peripheral part of the high nut closer to each plate material than the #1F2 thread is formed larger than the outer diameter of the left and right threads, and the female h thread threaded part is formed on the inner periphery of the tip of the high nut. This not only greatly shortens the time-consuming hji process, but also makes it easier for the plating solution to run out during plating, which also improves the efficiency of the plating process.
