DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the assembly jig of the present invention will be described below with reference to FIG.

The assembly jig 19 has a jig body 20, a screw member 21, and a bracket receiving fitting 22.

The jig body 20 is made of an angle material having a predetermined length, and bearing mounting members 23 are fixed to both ends. The bearings 24 and 25 are mounted on these bearing mounting members 23. A protruding member 26 is fixed to the side surface of the jig body 20 near one bearing mounting member 23 (upper side in FIG. 1). A fixing screw member 27 is screwed onto the protruding member 26,
A handle 28 is provided at one end of the fixing screw member 27. Further, a plurality of holes 30 for the jig setting fitting 29 are formed on one side surface of the jig body 20.
A bolt 31 screwed into the jig set fitting 29 is inserted into the hole 30. In addition, a slit 32 having a predetermined length is formed parallel to the length direction of the jig body 20 on a surface of the jig body 20 that is orthogonal to the surface in which the hole 30 is formed. The screw member 21 is formed to be slightly longer than the length of the jig body 20, one end of which is axially supported by a bearing 24 of the jig body 20, and the other end of which is a bearing 25.
The bearing 33 is pivotally supported and protrudes from the bearing mounting member 23, and a handle 33 is provided at the protruding portion. Further, a bracket-like bracket 22 having an upper surface for attaching the bracket 1 is fixed to the substantially center of the screw member 21. Then, by rotating the handle 33, the screw member 21 is rotated and the bracket receiving metal fitting 22 is moved along the slit 32.

Next, the operation of the assembly jig 19 will be described.

It should be noted that although two sets of the assembly jigs 19 are set, one set will be explained here because they perform exactly the same operation.

First, the jig setting metal fitting 29 is fixed to a predetermined hole 30 of the jig main body 20, and the jig setting metal fitting 29 is inserted into the lower surface of the pillar member 2 as a building member. Next, the handle 28 is rotated to bring the tip of the fixing screw member 27 into contact with the upper surface of the column member 2, and the handle 28 is further rotated to bring the tip of the fixing screw member 27 into pressure contact with the upper surface of the column member 2. In this way, the pillar member 2 is sandwiched by the fixing screw member 27 and the jig setting metal fitting 29 to fix the assembly jig 19 to the pillar member 2. Then, the handle 33 is turned so that the upper surface of the bracket receiving fitting 22 is aligned with the bracket mounting line 4 of the pillar member 2. After that, attach the bracket 1 to the upper surface of the bracket receiving bracket 22 with a hoist (not shown) or the like,
If necessary, the handle 33 is turned to slightly move the bracket receiving metal fitting 22 to adjust the position of the bracket 1 with respect to the bracket mounting line 4 and weld the bracket 1 and the pillar member 2. When welding is completed, the handle 33 is rotated to remove the bracket receiving bracket 22 from the bracket 1, and
The handle 28 is turned to raise the fixing screw member 27 to remove the assembly jig 19 from the pillar member 2.

The main assembly jig 19 can be attached to the pillar members 2 of a plurality of sizes by selecting the position of the jig set fitting 29 and rotating the fixing screw member 27.

FIG. 2 is a view showing another embodiment of the present invention, in which a side plate 34 is fixed in the longitudinal direction of the jig body 19. A plurality of holes 30 are formed in the side plate 34, and a magnetic member 35 is attached to the side plate 34 in these holes 30.
A bolt (not shown) for fixing to is inserted. Then, the assembly jig 19 is fixed to the steel plate 36 by magnetically attaching the magnetic members 35 to the side surface of the steel plate 36 as a building member, and the fixing position of the bracket 1 with respect to the steel plate 36 can be determined. ing. By using the magnetic member 35 in this way, the assembly jig 19 can be fixed to a building member having an inclined flat surface.

FIG. 3 is a view showing still another embodiment of the present invention, in which the jig body 19 is formed with two slits 32 of a predetermined length parallel to the longitudinal direction. A screw member 21 is provided corresponding to each of these slits 32, an arm member 37 is screwed into the screw member 21 substantially at the center thereof, and between these arm members 37. A bracket receiving fitting 22 is provided. And
As shown in FIG.
A round hole 38 and a long hole 39 are formed, and the round hole 38
The bracket receiving bracket 22 is fixed to the arm member 37 by bolts 40 through the elongated holes 39. Further, the side plate 34 of the jig body 20 is provided with two magnetic members 35. By providing the bracket receiving bracket 22 via the two screw members 21 in this manner, the position (for example, height) of the bracket receiving bracket 22 can be changed and the bracket receiving bracket 22 can be tilted. The bracket can be fixed diagonally to.

[0018]

As described above, according to the present invention, the assembly jig includes a jig body, a screw member pivotally supported by the jig body, and a screw member screwed to the screw member. The bracket has a flat plate-shaped bracket receiving bracket that is movable along the jig body when the bracket is bracketed by rotating the screw member to a predetermined position of the building member. Since the bracket is attached to the receiving metal and the bracket is positioned, temporary mounting of the bracket receiving metal is unnecessary, and fine adjustment of the mounting position of the bracket with respect to the building member can be freely performed by operating the handle. Also, after welding the bracket to the building member, the assembly jig can be removed from the building member, so there is no need to remove the bracket receiving metal fittings and grind the removed traces, which greatly improves work efficiency. And so on.
