As a conventional technique that improves this point, there is a structure as shown in Figs.
(Refer to Utility Model Publication No. 57-59529). The structure shown in FIG. 3 consists of main reinforcements 1, 1. The reinforcement structure 3 is made by winding rectangular hoop reinforcements 2 around ... at regular intervals, and spiral reinforcements are further placed around the outer periphery of the main reinforcements 1, 1°, which are located not at the corners but in the middle. 4 is reinforced. In the structure shown in FIG. 4, spiral reinforcements 4 are arranged on the inner circumference. Fifth

By arranging the structure independently of the outer reinforcement structure, after each reinforcement structure is assembled separately, the inner reinforcement structure can be inserted inside the outer reinforcement structure, or the inner reinforcement structure can be inserted into the inner reinforcement structure. The outer reinforcement structure can be placed on the outside of the reinforcement structure.

変形することにより行なえるため簡単となる。Next, the operation of the above embodiment will be explained. First, in terms of construction, after assembling both the reinforcement structures 3 and 7 separately as described above, the inner reinforcement structure 7 is inserted and arranged inside the outer reinforcement structure 3. Alternatively, they can be installed in the reverse order. In terms of earthquake resistance, the inner structure 7 takes care of the deformation of the core of the column, and the outer structure 3 takes care of the deformation of the outer periphery of the column, increasing the seismic strength as a whole. In the above embodiment, the vertical sub-reinforcements 8, 8. ...and hoop muscle 9°9. Although the inner reinforcing structure 7 is formed by bundling the two cylinders 8 and 9, the intersection of the two cylinders 8 and 9 may be welded by resistance welding or the like. According to this welded bond,
Since the stress distribution against deformation force is improved compared to wire binding, it is possible to further increase the strength in terms of earthquake resistance. Also, in terms of assembly, the hoop lines 9, 9. ...
In the rod-shaped state before deforming the main reinforcements 8, 8.・
... are arranged on a flat surface, each intersection is welded by resistance welding, etc., and then hoop lines 9°9
It is simple because it can be done by deforming g... into a square shape (FIG. 1) or a ring shape (FIG. 2).
更にラップ長の長さも針金結束の場合に比して短くする
ことができ、全体として材料の節減及び軽量化を図るこ

It may be formed only at the intersection with 8z, and the other intersections may be formed by wire binding.
