Rotating and moving the hexagonal nuts 23 and 33 is a very troublesome work and is not a waste of time, and a spring washer is additionally required to prevent loosening. There was a disadvantage.

The present invention solves the above problems, and the tightening nut does not separate from the turnbuckle portion in height adjustment of the floor surface, so that the nut tightening work is simple and the loosening effect is simple. An object of the present invention is to provide a floor bundle capable of realizing the above.

[0010]

In order to achieve this object, the floor bundle of the present invention has the following construction. The floor bundle includes a foundation fixing portion having a first screw rod into which a tightening nut is screwed, and a large pulling bearing portion including a second screw rod into which the tightening nut is screwed and threaded in the opposite direction. And a turnbuckle portion that connects the two screw rods by screwing, and tightening by rotation of the turnbuckle portion between the tightening nut and the end flange of the turnbuckle portion. It is characterized by the provision of nut temporary fixing means for preventing the use nuts from separating.

In the floor bundle having such a structure, the nut temporary fixing means is provided between the tightening nut (hexagonal nut) and the end of the turnbuckle. The temporary nut fixing means is, for example, a flat plate-like receiving plate, which locks around the end flange of the turnbuckle portion while retaining the hexagonal nut.

Therefore, by rotating the turnbuckle portion 1,
When the two threaded rods are extended, the hexagonal nut remains close to the end flange of the turnbuckle and is not separated by the temporary nut fixing means.

On the other hand, at the stage where the position adjustment of the floor surface is completed,
Tighten the oriented hex nut to the end flange of the turnbuckle. At the time of this tightening, when the hexagonal nut is strongly turned against the anti-rotation force (engagement force between the peripheral stop locking piece of the receiving plate and the end flange of the turnbuckle), the anti-rotation projection piece Be damaged. This enables tightening of the hexagon nut.

The tightening of the hexagonal nut compresses the inclined leaf springs interposed between the hexagonal nut and the turnbuckle portion (end flange), thereby exerting a loosening prevention function.

Further, circumferential stop projections (locking pieces) 44, 44 are provided on the remaining opposing sides of the receiving plate 41, and the circumferential stop projections 44 are provided on the end flange 1 of the turnbuckle portion 1.
The receiving plate 41 is temporarily fixed to the end flange 12 (11) in a circumferential stop manner by engaging the surface of the linear portion 14 of 2 (11) in a surface contact manner.

Further, the nut temporary fixing means (receiving plate 41) 4
A through hole 42 into which a screw rod is inserted is formed in the surface of the plate, and a loosening washer function portion 46 is provided in the surface of the receiving plate 41 via a plurality of cut grooves (notch grooves) 45. Has been.

The loosening washer function portion 46 is an inclined leaf spring in the embodiment as shown in FIGS. 1 and 2. The plurality of inclined leaf springs 46 are provided in a circle by a plurality of cutout grooves 45 formed in the surface of the receiving plate 41.

In the example of FIG. 2, the tip end of each of the inclined leaf springs 46 is twisted clockwise, and one end of the inclined leaf spring 46 is projected upward from the horizontal receiving plate 41, and the other end thereof is received. The lower end portion 46a is projected downward from the surface of the plate 41. The inclined leaf spring 46 of the nut temporary fixing means (receiving plate 41) on the side of the first screw rod 22 is formed by twisting the tip end portion in the counterclockwise direction.

Therefore, as shown in FIG. 1, in the loosening washer function portion (each inclined leaf spring) 46, the upper end portion 46b supports the bottom surface 33b of the hexagonal nut 33 (23) and the lower end portion 46a turns. It is in contact with the end flanges (upper end flange 12, lower end flange 11) of the buckle portion.

In the floor bundle having such a structure, as shown in FIG. 3, in the normal state, the hexagon nut 23 is temporarily fixed to the end flange 11 by the temporary nut fixing means 4,
The square nut 33 is temporarily fixed to the end flange 12 by the temporary nut fixing means 4.

When adjusting the height of the floor surface, from the normal posture shown in FIG. 3, the foundation fixing portion 2 is fixed to the bund stone A as shown in FIG. 4, and the large pull support portion 3 is fixed to the large pull B. By rotating the turnbuckle portion 1, the height of the large pull bearing portion 3 is adjusted, that is, the floor surface height is adjusted to be flush.

2) It is fixed to 1 by a circumferential stop projection 44.

Thus, even if the turnbuckle portion 1 is rotated, the hexagon nuts 23 and 33 are maintained in a state of being positioned close to the end flange 11 (12) regardless of the extension of the screw rods 22 and 32. Therefore, the tightening work of the hexagon nuts 22 and 33 after adjusting the floor surface height may be performed by simply tightening from the fixed position.

Further, as shown in FIG.
When the hexagon nuts 23 and 33 are strongly rotated against the locking force of No. 3, the circumferential stop projection 44 is damaged. As a result, the hexagon nuts 23 and 33 can be tightened.

By tightening the hexagonal nuts 23 and 33, the inclined leaf springs 46 interposed between the hexagonal nuts 23 and 33 and the end flanges 11 and 12 are compressed and exert a loosening preventing function.

[0033]

As described above, according to the present invention, the nut temporary fixing means is interposed between the hexagonal nut screwed to the screw rod and the end flange of the turnbuckle portion to which the screw rod is screwed. Since it is decided to be installed and deployed, the hexagonal nut is not separated from the turnbuckle portion even when the turnbuckle portion is rotated, and the normal position is maintained.

Therefore, when the hexagonal nut is tightened to the turnbuckle after adjusting the floor height as in the conventional case, it is troublesome to move the separated hexagonal nut to the end flange of the turnbuckle. The problem is solved, and the work of tightening the hexagonal nut can be performed extremely reasonably and easily.

Further, since the loosening washer function portion (sloping leaf spring portion) is provided in the temporary nut fixing means, the loosening prevention function is exerted at the same time by tightening the hexagonal nut. It has an excellent effect that the object of the invention is achieved, such that disadvantages such as the need for a washer can be eliminated.
