Definitions
- t / w ⁇ l is satisfied as described above even outside the range of the above equation (3), that is, within the range of the above equation (2).
- the cross-sectional shape is such that R / t ⁇ 2.8, that is, it is approximately rectangular, sufficient strength can be obtained in the bent portion.
- the above-mentioned substantially rectangular shape may be an elliptical shape in addition to the rectangular shape whose short side is curved outward as described above.
- Equations (1) and (2) above are valid when the bending sections are independent. If there are two or more bending sections, one bending section is replaced by another bending section. A condition that does not affect the condition is required.
- Fig. 6 shows an example of this experiment.
- the thickness direction of the reinforcing bar 4 of the same type as that shown in the first experimental example another persimmon that is one size larger than this reinforcing bar 4 is shown. Strong muscles 4a are superimposed on each other to match the irregularities.
- reinforcing bars consisting only of FRP were shown.
- a coating layer 7 made of a thermoplastic resin may be provided on the surface thereof.
- the convex portion 5 shown in FIG. 7 is also made of a thermoplastic resin. In some cases, the convex portions 5 are not provided.
- the coating waste 7 does not have to be a thermoplastic tree US as shown in FIG.
- a coating layer 7 is formed by spirally winding a tape around an FRP core 6, or a coating layer 7 is formed by sandwiching the FRP core 6 between two films. It is conceivable.
