ができ、当該横架材３の強度の低下が抑えられる。First, as shown in FIG. 1, an operator inserts the foundation bolt 4 into one of the elongated holes 11a of the substrate 11 of the floor structure support tool 10, and the center of the bolt 12 is located at the center of the foundation concrete 1. It is positioned and placed so that it is positioned, and fixed by the nut 6. As a result, even when the foundation bolt 4 is installed at a position displaced from the center of the foundation concrete 1, it becomes possible to match the center of the bolt 12 with the center of the foundation concrete 1. Therefore, the bolt hole 3a through which the bolt 12 is inserted can be formed at the center of the horizontal member 3, and the decrease in the strength of the horizontal member 3 can be suppressed.

The lower end surface is clamped and fixed to the upper surface of the horizontal bridge member receiver 13. The horizontal bridge member 13 and the joint 15 are firmly fixed to the bolt 12 by the effect of the double nut. As a result, the horizontal bridge receiver 13 is horizontally placed on the foundation concrete 1,
It can be positioned easily and accurately. In addition, the so-called top-end leveling work for making the upper surface 1a of the basic concrete 1 horizontal and flat becomes unnecessary, and the construction becomes easy. In this way, the worker installs the floor structure support tool 10 at the position of each foundation bolt 4 installed on the foundation concrete 1, and as shown by the two-dot chain line, each bolt hole 3a of the horizontal member 3 The joints 15 and the bolts 16 are inserted into the above, and the horizontal members 3 are placed on the respective horizontal member receivers 13. As a result, the horizontal member 3 is easily and horizontally positioned and installed on the basic concrete 1 at a predetermined height.

力により、ナット２５の緩みが防止される。In this state, the lower surface of the horizontal member 3 faces the upper surface 1a of the basic concrete 1 with a gap required for ventilation (ventilation) under the floor. Therefore, no ventilation packing is required, and a ventilation gap is formed between the horizontal bridge member 3 and the upper surface of the basic concrete 1, so that ventilation under the floor becomes extremely good. Next, the worker bolts 1
Turn 6 to match the height of the horizontal member 3. For example, as shown by the solid line, the upper portion of the bolt 16 is projected above the horizontal member 3, the outer ring 21 and the inner ring 22 of the fixing member 20 are attached as shown, and the washer 23, the coil spring 24, and the washer 23 are attached. The fixing nut 25 is screwed in through. When the nut 25 is tightened, the coil spring 24 is contracted, and the spring force of the coil spring 24 reduces the inner ring 22.
Is pushed into the tapered hole 21a of the outer ring 21, and accordingly, the inner ring 22 contracts while pressing the outer ring 21, and the locking claws 22a bite into the screw on the outer peripheral surface of the bolt 16 to move in the opposite direction. Prevent movement and lock in place. As a result, the horizontal member 3 is constantly pressed and fixed to the horizontal member receiver 13. Further, the spring force of the coil spring 24 prevents the nut 25 from loosening.

る。The inner ring 22 is movable in the direction in which the small-diameter end side advances with respect to the bolt 16 (downward in the figure), so that when the horizontal bridge member 3 becomes thin due to aging, the inner ring 22 is accompanied by it. Ring 22 is coil spring 2
The outer ring 21 is moved while being pressed by the spring force of No. 4, and is locked and fixed by the locking claw 22a at a position balanced with the spring force. This prevents looseness of the horizontal member 3 and loosening of the nut 24 due to thinning of the wood. In this way, the fixing member 20 fixes the horizontal member 3 to the horizontal member receiver 13.

The fixing member 20 may be housed in the counterbore 3c. In addition, a plurality of locking claws may be formed on the lower surface of the outer ring 21 so as to project in the circumferential direction so as to be locked on the upper surface of the horizontal member 3. As a result, the bolt hole 3a becomes
On the other hand, lateral displacement of the outer ring 21 can be prevented even if the hole is slightly larger. Further, the horizontal member 3 may be fixed by using a washer or a spring washer and a fixing nut 25 instead of the fixing member 20.

Become. In such a case, by turning the nut 37 welded to the horizontal bridge member 13 to the right, the horizontal bridge member 13 is moved upward (raised) with respect to the bolt 36 and pushes up the horizontal bridge member 3. On the other hand, the bolt 16 and the fixing nut 25 that are tightening the horizontal member 3 are right-handed screws, so that the bolt 16 is slightly loosened. However, the bolt 16 and the joint member 38 that rotates integrally with the horizontal member receiver 13 immediately come together. And never loosen more than necessary. Further, since the bolt 36 has a large pitch of the threaded portion 36a, the bolt 36 can be greatly moved upward by slightly rotating the horizontal member receiver 36, and the workability can be improved. Although the lower bolt 36 has a left-hand thread and the upper bolt 16 has a right-hand thread, conversely, the lower bolt 36 may have a right-hand thread and the upper bolt 16 may have a left-hand thread.

Hold the central portion 47c of the bolt 47 with a wrench and turn it to the right.
As the bolt 47 rotates to the right, the bolt 47 rises while coming out of the support column 46. Upper part 4 of bolt 47
7b is a right-hand screw, and the horizontal bridge member receiver 13 rises as the bolt 47 rotates in the right direction, and pushes up the horizontal bridge member 3. At this time, the horizontal member 3 is fixed by the fixing member 20. The left screw 47a 'of the lower portion 47a of the bolt 47 is
Since the pitch is set to be larger than that of the right screw 47b ′ of the upper portion 47b, the horizontal member 3 can be largely lifted by slightly rotating the bolt 47. The bolt holes 3a of the horizontal member 3 may be counterbore holes. Further, as the fixing member, a washer and a bolt may be simply used instead of the fixing member 20.
