良好である。□□□) As described in detail, according to the present invention, the structural member 3 is stretched by wrapping the rope 5 made of high-performance continuous fibers that are lightweight and strong between the main reinforcements 1. Since the reinforcement is adopted, the reinforcement work of the structural member 3 can be performed more easily and in a shorter time than the method of bending and wrapping reinforcing bars.Furthermore, since the rope 5 has the property of being easily bent, There is no need for any special bending process that is required when using reinforcing bars, making it easy to bend and work, and the workability is extremely good.

。）。In the above embodiment, the case where the rope 5 is simply wrapped around the main reinforcement 1 in a loop is described, but as shown in FIG. The rope 5 may be securely fixed to each main reinforcement 1, and the rope 5 may be securely fixed to each main reinforcement 1 as shown in FIGS.
It may also be wound spirally between the two (in the case of FIG. 4, the rope 5 is further wound around each main reinforcement 1 at least once). Furthermore, as shown in Figures 5 and 6, it is also possible to stretch the rope 5A between the main reinforcements 1 diagonally (in the case of Figure 6, the rope 5A can be stretched around each main reinforcement 1). (The main reinforcing bars 1 on the diagonal lines are connected with ropes 5A.)
更に、第７図に示すように、輪状に巻かれた一プ５の内
