BACKGROUND ART Conventionally, long steel structural materials have been used for pillars and beams of prefabricated residential buildings, and mounting holes and brackets have been formed to connect various members to each. To be done. Of these, a nut is fixed to a predetermined mounting hole in advance in order to simplify work at a construction site. For example, in a box type living room unit, an outer wall panel and an eaves unit are attached along a beam member. Therefore, holes are arranged in the C-shaped steel for beams along the longitudinal edge, and a nut is welded and fixed to the back side of the predetermined hole. Further, also in the rectangular steel pipe for a column, similar holes and nuts are formed near the end openings following the beam.

Here, the nut fixation as described above is not performed for all long structural members, but is performed only for a predetermined hole. Therefore, the work of fixing the nut is
In a finishing process or the like in a production line for a long structural material, workers selectively perform it according to the long structural material.

[0004]

By the way, when fixing the above-mentioned nut, the nut is kept in contact with the predetermined hole of the long structural material by holding it, and the periphery thereof is welded to the surface of the long structural material. Work is required. At this time, it is necessary to accurately hold the back surface of the nut so that the back surface of the nut closely contacts the surface of the long structural material.

However, in welding by a worker, it is necessary to hold the nut with one hand and operate the welding machine with the other hand, which may result in insufficient positioning and holding of the nut, and when the nut is small. Has a problem that it is difficult to operate, for example, it is necessary to hold the nut near the welding site. Especially in the line processing of long structural materials,
Due to the complexity of the operation as described above, it is difficult to shorten the time required for fixing the nut, which causes a problem of reducing the production efficiency.

An object of the present invention is to provide a nut positioning holder which can fasten a nut at a predetermined position quickly and reliably.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show a nut positioning holder 10 according to the present invention. In this embodiment, C
Nut 22 when welding nut 22 to flange 21 of shaped steel 20
Positioning and holding will be described. The nut positioning holder 10 includes a body 11 made of iron, and a holding portion is provided on the surface of the body 11.
12 and an abutting surface 13 are formed, and a holding portion 14 is fixed to the back surface.

The holding portion 12 is a concave portion formed in the main body 11 and can accommodate the surface side of a predetermined nut 22. Abutment surface
13 is formed by a surface of a spacer 16 having a predetermined thickness fixed to the main body 11 with a bolt 15, and the surface of the spacer 16 is flush with the back surface of a predetermined nut 22 housed in the holding portion 12. The one with the proper thickness is selected. Clipping part 14
Is formed of a substantially U-shaped elastic material, the base end side of which is fixed to the back surface of the main body 11, and an arcuate portion 17 is formed at the tip so as to substantially face the contact surface 13. .

In this embodiment, the nut 22 is housed in the holding portion 12 of the main body 11, the nut 22 is placed along the back surface of the flange 21, the main body 11 is inserted from the peripheral side, and the holding portion 14 is held. Open and open the arc part 17 of the tip to the flange 21.
The flange 21 is sandwiched between the contact surface 13 and the contact surface 13. As a result, the main body 11 has the nut 22 and the contact surface 13
The nut 22 is clamped in parallel with the flange 21 via, and the back surface of the nut 22 is held in close contact with the flange 21. Then, by appropriately moving the clamped main body 11 and aligning the shaft of the nut 22 with the hole 23 of the flange 21 or the like, the desired positioning is correctly performed.

According to the present embodiment as described above, the nut 22 can be properly held without using hands for welding or the like. In particular, by contacting the flange 21 via the contact surface 13, the main body 11 becomes parallel to the flange 21, and the back surface of the nut 22 can be brought into close contact with the flange 21.
Further, since the clamping portion 14 performs elastic clamping, it can be appropriately moved along the flange 21, and the work of adjusting the nut 22 to the position corresponding to the hole 23 can be facilitated.
