FIG. 1 shows an example of a structure of a connecting portion in which the upper and lower column members 1 and 2 are cylindrical, and the column member 1 is placed on the top end of the column member 2 and connected.

In each of the column members 1 and 2, an erection piece 3 is fixed on the outer peripheral surface adjacent to the connection end so as to extend in the longitudinal direction of the cylinder, and a plurality of erection pieces 3 are appropriately arranged in the circumferential direction. Each of these erection pieces 3 is provided with a bolt hole 30. In the prior art, a splice plate 4 described below is brought into contact with the erection piece 3 to perform so-called bolt fastening with a bolt and a nut. In the present invention, the bolt fastening is performed via the vertical pin jig 5.

That is, the vertical pin jig 5 is formed by laminating two plate members 50, 50, and a long groove 51 is formed on one side surface with respect to the mating surface of the two plate members 50, 50, and is adjacent to the long groove 51. Similarly, a pin hole 52 is formed on the mating surface of the two plate members 50, 50, and extends along the length of the long groove 51. And the long groove 51
Bolt holes 53 corresponding to the above-described bolt holes 30 of the erection piece 3 are appropriately provided at the two plate members 50 and 50 corresponding to the side walls of the erection piece 3. That is, the vertical pin jig 5 has its long groove 51
Are covered by the erection piece 3 and engaged, and are fixed to the erection piece 3 by bolting connecting the bolt holes 30 and the bolt holes 53. Here, since the erection piece 3 extends in the longitudinal direction of the column members 1 and 2 and is fixed, the erection piece 3 extends in the column center direction, and therefore, the pin hole 52 of the vertical pin jig 5 fixed to the erection piece 3. Is
Since it extends along the length of the long groove 51 covered by the erection piece 3, it extends in the column direction. A through pin 6 described later is inserted into the pin hole 52.

The through pin 6 has a shaft that is inserted from the head 60 and extends through the pin hole 52 of the vertical pin jig 5, has a shaft length longer than the entire length of the pin hole 52, and has a taper 61 at the shaft tip. Provided. When the through pin 6 is constructed, the pin hole 52 of the vertical pin jig 5 fixed to the erection piece 3 of the upper column member 1 is formed.
The head 60 is separated from the edge of the pin hole 52 by the interposition of the stopper spring 7 at this time.

In the vertical pin jig 5 fixed to the erection piece 3 of the lower column member 2, one of the openings T of the pin holes 52 is cut in a substantially horn shape, and the tapered opening T is formed.
Secured side up. Here, since the through pin 6 is inserted into the pin hole 52 of the vertical pin jig 5 of the upper column member 1 and is in a hanging state at the time of construction, by removing the stopper spring 7, the opposite lower vertical pin Pin hole 52 of jig 5
FIG. 5 shows the insertion state. At this time, the lower pin hole 52 faces the connection end on the side of the tapered opening T, and the through pin 6 has the taper 61 at the tip of the shaft. Can be inserted smoothly.

On the other hand, the splice plate 4 is set to have a length that extends over the two erection pieces 3, 3 that are to be vertically arranged on the outer peripheral surfaces of the column members 1 by placing the column members 1 on the top end of the column member 2, A bolt hole 40 corresponding to the bolt hole 30 of the erection piece 3 is appropriately provided. Since the vertical pin jigs 5 are respectively fixed to the two erection pieces 3, 3 arranged vertically, the splice plate 4 is arranged on the front and back of the two vertical pin jigs 5, 5 arranged vertically. The inner erection pieces 3, 3 are brought into contact with each other on the front and back sides, and are fastened with bolts so as to sandwich them.

According to such a configuration, as shown in FIG. 5, the through-pin 6 is inserted between the pin holes 52, 52 of the vertical pin jigs 5, 5, which are arranged vertically when building. In other words, the pin hole
The fact that the through pin 6 can be inserted between the upper and lower portions 52, 52 means that there is no step or deviation between the upper and lower column members 1 and 2 and that they are at the correct positions. Therefore, first, the upper and lower vertical pin jigs 5, 5 are constructed so as to be substantially aligned, and if the through pin 6 is pushed into the lower pin hole 52 from above, there is a slight displacement in the lower pin hole 52. Even if there is a slight rotation with the insertion of the through pin 6, the position is correctly adjusted and corrected to the correct position. Since this is a simple operation of merely inserting the through pin 6, the positioning can be easily performed, and the bolting of the splice plate 4 is performed in a state where the through pin 6 is inserted, that is, the position is correctly adjusted. In this case, the work can be easily performed. At this time, there is no need for an operator for alignment as in the related art, so that the workability is excellent. Also,
Since the positioning is performed accurately by inserting the through pin 6, the building is performed with high accuracy.

<< Effects of the Invention >> As described above in detail in the embodiment, according to the connection structure of the column members according to the invention, the through pins are inserted between the pin holes of the vertical pin jigs arranged vertically at the time of construction. This means that there is no step or displacement between the upper and lower pillar members, and the pillar members are at the correct positions.

In other words, the position is correctly adjusted by a simple operation of merely inserting the through pin, and the position can be easily corrected. The bolts of the splice plate need only be inserted while the through pin is inserted. Excellent. Also,
