Abstract

PURPOSE:To obtain a simple application method requiring no double-nuts for preventing loosening, by interposing a fixture between a bolt and a deformed part defined in a high nut after the high nut is screwed for height-adjustment in an erected bolt on a foundation surface. CONSTITUTION:A bolt 2 fitted on an installing plate 1 freely rotatably is erected on a foundation surface 25. Next, a high nut 6 in which a female screw 7 is formed at the lower part thereof and a deformed section-hole 8 such as a square, hexagonal, or petal shape is formed at the upper part is provided and secured to a support plate 5. Next, the bolt 2 is screwed into the nut 6 and a fixture 3 made of an elastic member is inserted not to be loosened in a fitting hole 29 of the fixture made in the bolt 2. And after the height is adjusted, floor panels 24 are laid on a plate 5 via a floor joist 23. The fixture may be made of a plate, plug, or clip and the deformed part may be arranged at the outer periphery. In this way, it is enough to only screw a bolt and hence, the work ability can be remarkably improved.

(Conventional technology and its problems) Recent intelligent buildings are equipped with a free access floor panel (24°) on the floor support bracket (B) to accommodate OA equipment.
Raised floors are often used. Now, since the height of this free access floor from the concrete slab that is the foundation surface (25') varies, the height of the bolts (2') and commercially available full screws as shown in Figure 8 is different. It was designed to be adjusted with floor support fittings (B) for free access floors placed horizontally at (8'). However, in this case, after adjusting the height of the free access floor, a double nut was fixed using a high nut (6') and a fixing nut (26°), but fixing with a double nut was time-consuming. Otherwise, the height that was adjusted when hanging the nut may be incorrect, or the floor support bracket (
There were drawbacks such as B) being misaligned. Another problem was that when the floor height was low, there was not enough space to hang nuts, making it difficult to do the work.
Therefore, if the double nut hooking was omitted, the bolt (2°) would rotate little by little due to vibration, causing the high nut (6') to sink, creating an uneven surface on the free access floor. Therefore, it was desired to propose a floor support bracket (B) that can be adjusted simply by turning a bolt (2 degrees). (Object of the invention) The present invention has been made in view of the drawbacks of the conventional example, and
The purpose of this is that high nuts and bolts can be fixed just by turning the bolts, which not only improves work efficiency, but also prevents unevenness of free access floors due to loosening of screws during use. There is no floor support hardware available. (The following is a margin) (Means for solving the problem) In the following, in claim (1) showing the first embodiment of the present invention, in order to solve the above problem, ■ Mounting on the base surface (25) A bolt (2) is rotatably set up on a mounting plate (1) to be mounted, and a locking member (3) is attached to the outer peripheral surface of the bolt (2) so that its tip protrudes.

After that, remove the free access floor panel (24) as described above.
All you have to do is install the . (The following is a blank space) (Effects) In the first aspect of the present invention, since the locking member of the bolt is engaged with the vertical groove formed in the axial direction of the irregularly shaped large diameter hole,
There is no need to hang double nuts as in the conventional example, and the high nut and bolt can be fixed after adjusting the height just by rotating the bolt, which not only improves work efficiency, but also prevents the thread from loosening during use. This has the advantage that there will be no unevenness of the free access floor caused by this. In claim (2), a cap having an irregularly shaped hole or irregularly shaped protrusion is fitted onto the tip of the bolt l and inserted into the large diameter hole of the tall nut to engage the engaging ridge of the cap with the ml. Therefore, as in claim (1), the height of the high nut and bolt can be fixed after adjusting the height by simply rotating the bolt, improving work efficiency, and at the same time, the threaded part can be removed during use. There will be no unevenness of the free access floor due to loosening.Furthermore, since it is held by the cap, the 5th screw is supported at two points, the top and the bottom, and the bolt and the high nut 1 are supported as in the case of a full screw. The screw connection with ... is stable.Claim (
In case 3), since the fixation is similarly performed using a cap, the same effect as in claim (2) can be obtained. In claim (4), since the rotation stopper is inserted into the large diameter hole of the high nut and the engagement ridge of the cap is engaged with the vertical groove, the rotation stopper can be simply inserted from above. This allows the high nut and bolt to be fixed via a rotation stopper, and has the advantage that bolt adjustment is very easy, similar to the above embodiment. In claim (5), since the rotation stopper clip attached to the top of the bolt is locked in a clip hole drilled in the support plate around the bolt, the bolt can be removed by an operation from the outside. It can be fixed and the bolt adjustment is very simple.In claim (6), the rotation stop bar is inserted into both vertical grooves at the point where the inner and outer m grooves match, so the claim is Like (4), bolt adjustment is easy.
