In order to explain the structure and characteristics of the frame structure of the column structure using the helical muscle, a specific example will be given and described in detail below with reference to the drawings.

The structure of the column structure 100 using the spiral muscle of the present invention disclosed in FIGS. 1 a to 1 b, the first spiral muscle 200, the second spiral muscle 300, and the reinforcing reinforcing bar 700.

The first spiral bar 200 and the second spiral bar 300 are formed by winding reinforcing bars in a ring shape, and gaps 210 and 310 are formed between the reinforcing bars that draw a circle. One end of the outer periphery of the first spiral muscle 200 on the second spiral muscle 300 side is a connection side 220.

The first spiral muscle 200 and the second spiral muscle 300 are installed so that their axial directions are parallel to each other, and the connection side 220 of the first spiral muscle 200 is overlapped with a part of the second spiral muscle 300 to overlap the region. 400 is formed. In this case, the portion on the connecting side 220 of the reinforcing bar constituting the first helical bar 200 is inserted into the gap 310 of the second helical bar 300, and a part of the reinforcing bar constituting the second helical bar 300 is also included in the gap of the first helical bar 300. They are inserted into 210 and overlap each other. In this state, the places where the reinforcing bars of the first helical bar 200 and the third helical bar 300 cross each other are welded, connected, or connected by other appropriate methods.

  On the other hand, a reinforcing bar 700 is provided in advance inside the first spiral bar 200 and the second spiral bar 300. The reinforcing reinforcing bar 700 is intended to reinforce the structure of the first helical bar 200 and the second helical bar 300, and also has an action of limiting the range of the overlapping region 400 described above. That is, two reinforcing reinforcing bars that limit the overlapping range of the outer circumferences of the first spiral bar 200 and the second spiral bar 300 are arranged in the axial direction, two inside each of the first spiral bar 200 and the second spiral bar 300. And at least one or more other appropriate positions inside the first spiral muscle 200 and the second spiral muscle 300 are provided only for the purpose of reinforcement.

The reinforcing steel bars 700 are similarly connected or connected by other appropriate methods.

  As shown in FIG. 1c, the frame structure of the column structure using the spiral streaks described above is a column structure having a polygonal cross section when a formwork is provided along the shape of the outer periphery and concrete is placed. can get. As a matter of course, by changing the shape of the formwork, for example, a columnar structure having a cross section of an ellipse, a rectangle or the like can be obtained.

In the embodiment, the width of the gap 210 is equal to the width of the gap 310. Therefore, when the 1st spiral muscle 200 and the 2nd spiral muscle 300 are piled up, the reinforcing bar which constitutes the 1st spiral muscle 200 and the reinforcing bar which constitutes the 2nd spiral muscle 300 are alternately overlapped. However, the width of the gap 210 may be different from that of the gap 310 due to design requirements. For example, the outer peripheral frame of the reinforcing bars of the first spiral bars 200 constituting the two gaps 210 of the first spiral bars 200 may be changed so as to be inserted into the gap 310 of one second spiral bar 300. Such a change is not an indispensable element for achieving the purpose of the present invention, in which a part of the outer peripheral frame of the two helical muscles is overlapped to obtain a framework of a column structure having a composite structure, and therefore will not be described in detail. .

Moreover, the 1st spiral reinforcement 200 and the 2nd spiral reinforcement 300 are formed by winding a reinforcing bar in a wire ring shape as described above. The inner diameter is the same for both the first spiral muscle 200 and the second spiral muscle. However, the inner diameter may be changed depending on the design needs. Further, the first spiral line 200 and the second spiral line are wound in a circle, but this may be changed to an ellipse, a rectangle, or a polygon. In addition, the reinforcing bars that form the first spiral bar 200 or the second spiral bar 300 may be formed by winding a reinforcing bar whose diameter decreases from one end to the other end. These changes are not indispensable elements for achieving the purpose of the present invention, in which a part of the outer peripheral frame of the two helical muscles is overlapped to obtain a framework of a column structure having a composite structure, and therefore will not be described in detail. .
