Description of the Related Art In steel-framed or steel-framed reinforced concrete buildings, the correctness of the columns, beams, etc. constructed, falling, entering, entering, leveling, bending, etc., before the steel members are fully joined. (Hereinafter referred to as “building”). For example, when the column is a square steel pipe, as shown in FIG.
Then, after the columns E are sandwiched between the splice plates P and temporarily tightened with the high-strength bolts B to temporarily join the columns C together, the double-screw screw jack 50 or the like is attached to the erection piece E, Due to the extension of the screw jacks 50 on both sides of the column C,
It is general that the pillars C are re-installed and then the pillars C are permanently joined by welding. FIG. 5 is an assembly diagram showing the screw jack 50 attached to the erection piece E attached to the column C in an easily understandable manner. As can be seen from the figure, since the distance between the bolt heads 52 can be adjusted by turning the nut 51, the distance between the screw holes Eh of the erection piece E fixed to the bolt head 52 can be adjusted, and as a result, The pillar C can be rebuilt.

The opposite end of the screw hole 31 is fitted with the convex portion 22 having the circular cross section. A mating recess 32 is provided. Here, the nut 30 has a polygonal cross section in consideration of the engagement with the tool when turning it using a tool, and further aims at reducing the friction with the shaft supporting member 20 when turning, and is close to the shaft supporting member 20. The cross section was as thin as possible.

2 and the concave portion 32 in the nut 30 are cylindrical, and do not hinder the rotation of the nut 30 when it is turned.
The function of supporting the shaft so that 0 does not tilt.
Therefore, the convex portion 22 and the concave portion 32 are not limited to the columnar shapes as shown in FIG. Further, since the convex portion 22 and the concave portion 32 only need to produce the above-described operation and effect, the convex portion 22 and the
May be combined with a concave portion and the concave portion 32 of the nut 30 as a convex portion. Further, the lengths of the convex portions and the concave portions are set so as not to hinder the attachment of the steel member rebuilding device 40 according to the present invention to the erection piece E, as described later. .

And the nut 30, and by combining these three members, it is possible to configure the steel member re-installation device 40 according to the present invention, and the following operation is achieved. That is, the steel frame member re-installation device 40 according to the present invention is used in the form shown in FIG. 2, and the distance between the screw hole 11a and the screw hole 21a in FIG. 1 can be easily increased. Obviously it is not. Because the screw hole 11a and the screw hole 21
This is because, when increasing the distance to a, the steel column C is lifted against the weight of the steel column C. Then, by turning the bolt 30 in the direction of the arrow shown in the figure, the engagement between the screw rod 12 and the screw hole 31 produces a screw action, and the distance between the screw hole 11a and the screw hole 21a can be increased. At this time, the nut 30 is
Since the nut 30 is pivotally supported by the engagement between the concave portion 32 and the convex portion 22, the above-described screw action can be sufficiently exerted without the nut 30 being displaced with respect to the pivot support member 20. Conversely, when the distance between the screw hole 11a and the screw hole 21a is reduced, it is apparent that the nut 30 may be turned in the direction opposite to the arrow shown in the figure.

図が図２である。Next, an embodiment of the use of the steel frame member rebuilding device 40 according to the present invention will be described with reference to FIG. First, an erection piece E temporarily attached to both sides of a built-up steel column C is sandwiched from both sides with a splice plate P, and temporarily tightened with a high-strength bolt B to form the column C. Is temporarily joined. Next, the steel member rebuilding device 40 according to the present invention is attached. Generally, with the screw rod 12 screwed into the screw hole 31 as much as possible, an erection piece E is sandwiched between the two plate members 11b of the bolt 10 to correspond to the screw hole 11a of the bolt 10. The bolt 10 and the nut 30 are attached to the erection piece E by matching the screw holes Eh. Similarly, the erection piece E is sandwiched between the two plate members 21b, the screw holes 21a are matched with the corresponding screw holes Eh, and the shaft support member 20 is attached to the erection piece E. At this time, as described above, the protrusion 2
Since the length 2 does not hinder the mounting, the bolt 10, the nut 30, and the shaft support member 20 can be mounted on the erection piece E in this manner. Finally, the nut 30 is turned to fit the projection 22 of the shaft support member 20 into the recess 32 of the nut 30. In this manner, the installation of the steel frame member re-installation device 40 to the erection piece E is completed, and FIG. 2 shows this state.

うことができる。After the steel member rebuilding device 40 according to the present invention has been mounted in this manner, the nuts 30 on both sides of the column C are appropriately rotated by using a tool such as a torque wrench, thereby obtaining the screw as described above. Hole 11a and screw hole 21
The distance to a can be adjusted, that is, the pillar C can be rebuilt.

は充分である。At this time, it should be noted that there is a limit to the amount by which the distance between the screw hole 11a and the screw hole 21a can be adjusted using the steel member rebuilding device 40 according to the present invention.
When the nut 30 is turned over beyond the adjustable length, ie, within the screw stroke, at which the screw action between the screw rod 12 of the bolt 10 and the screw hole 31 of the nut 30 can be exerted at the maximum. The bolt 10 will come off. However, in reality, the steel member rebuilding device 40 corrects the deviation of the vertical angle of the long steel column at the base of the steel column. It is enough for rebuilding.

で、問題はないと言える。[0015] Further, in connection with the above, another thing to be noted is that the pillar C to be rebuilt is a steel material, so that one pillar C is sunk into another pillar C. That is impossible. Specifically, when rebuilding the pillar C by extending one of the steel frame member rebuilding devices 40 on both sides of one pillar C, the screw stroke of the steel frame member rebuilding device 40 is performed. In the case where the screw stroke is insufficient to make the steel frame member vertical, the rebuilding device 40 for the steel member on the opposite side is shortened to shorten the column C. It would be nice if rebuilding could be done, but that is not possible. However, as described above, the screw stroke is actually 10 mm.
There is no problem because it is enough to rebuild the steel column.

できるものである。When the rebuilding of the pillars C is completed as described above, the pillars C are permanently joined by welding, the steel frame member rebuilding device 40 is removed, and the erection piece E is removed.
Disconnect. In this manner, the re-installation of the column C can be performed easily and reliably by using the steel-frame member re-installation device 40 according to the present invention. In addition, here, the rebuilding of the column related to the square steel pipe has been described as an example, but the same applies to the case of the column related to the H-shaped steel, and the rebuilding of the beam can be performed in the same manner. In addition, the steel member re-installation device 40 according to the present invention may be used upside down from the state shown in FIG. 1 or may be used sideways.

However, the time required for screw processing is reduced by that much, and the configuration is made without using a left screw which is not generally used, so that a significant cost reduction can be achieved. As a result, the construction cost can be reduced.
