At least two sets of long rods 1 extend in the radial direction as a set, and a plurality of sets of two types of bolt insertion holes 3 and 4 having different directional directions are alternately bored, and one end of them has a large diameter. Parts 3a and 4a are provided. or,
The short round bar 2 is formed with at least two bolt insertion holes 5 extending in parallel in the radial direction.

In this embodiment, as shown in FIG. 3, the axis of each bolt insertion hole 3, 4, 5 is the center O1, O2 of the round bar 1, 2.
It is located slightly offset to one side.
Of course, unlike this, the bolt insertion holes 3, 4, and 5 may be provided so as to pass through the centers of the round rods 1 and 2. Further, the axes of the two types of bolt insertion holes 3 and 4 on the long round bar 1 have a predetermined angle R
The only direction is changing.

Then, the assembling is performed as shown in FIG. 1 and FIG. After arranging a plurality of long round bars 1 in parallel, first, between the two long round bars 1 located on the left side in FIG. 1,
A short round bar 2 is arranged so as to be located in a portion of the bolt insertion hole 3 having the same directing direction, and is similarly placed in a portion of the bolt insertion hole 4 having the same directing direction between the next long round rods 1 so as to be short. Place a round bar. Therefore, the short round bars 2 are arranged alternately between the long round bars 1 one by one. The present invention in which the short round bars 2 are arranged in the length direction is arbitrarily selected according to the length of the long round bars 1.

In this state, two bolts 6 are inserted into one of the bolt insertion holes 3 of the two long round bars 1 and the bolt insertion hole 5 of the one short round bar 2.
And the nut 7 is screwed into the threaded end portion of the bolt 6 so that the three adjacent rods 1, 2
Will be tightened together as a set. Also, the other long bolt rod 2 has a bolt insertion hole 4 and one short rod rod 2
Two bolts 6 are respectively inserted into the bolt insertion holes 5 of the above, and a nut 7 is screwed into the threaded end portion of the bolts to include one of the three round bars 1 and 2. Adjacent three round bars 1, 2 form a set and are clamped and fixed to each other. The heads of the bolts 6 and nuts 7 are arranged in the large diameter portions 3a, 4a of the bolt insertion holes 3, 4.

In this case, the short round bars 2 are alternately arranged at predetermined intervals in the axial direction, and the two types of bolt insertion holes 3 and 4 on the long round bar 2 extend in different directions by a predetermined angle R. Therefore, the space S between the short round bars 2 is used to insert the bolt 6 into the bolt insertion holes 3, 4, and 5 and
It is possible to easily screw the nut 7 into the round bar. By tightening and fixing the three adjacent rods 1 and 2 by alternately shifting them in the juxtaposed direction of the rods 1 and 2, A plurality of round bars 1 and 2 can be assembled in an arc shape.
