引掛けるものである。In FIG. 3 showing an embodiment of the present invention, l is a metal joint, and a step 1b is formed on the outer circumferential surface, which is the bonding surface of the tip of the cylindrical portion 1a of the metal joint 1. The tip side has a large diameter. Further, 4 is an adhesive FRP layer interposed between the cylindrical portion 11 of the metal joint 10 and the end of the FRP pipe 2 into which it is fitted. This FRP layer 4
is a base material such as glass cloth impregnated with adhesive, which is wound around the outer periphery of the cylindrical part 1a of the metal joint 1, and then inserted into the FRP pipe 2 and heated at a predetermined temperature. hardened. Alternatively, the adhesive FRP layer 4 may be wound around the Fi metal joint 1, then hardened, inserted into the FRP pipe 2 via an adhesive, and bonded thereto. Then, the 10-stage metal joint 1b is inserted into the FiFRP layer 4 and hooked thereon.
上述のような接合方法によって構成された継手部材は、
一般にＦＲＰどうしの接着力はＦＲＰと金属との接着力
に比べて非常に大きいので、ＦＲＰパイプ２とＦＲＰ層
４との間の接合が強固であ＃）。The joint member constructed by the above-mentioned joining method is
Generally, the adhesive force between FRPs is much greater than the adhesive force between FRP and metal, so the bond between the FRP pipe 2 and the FRP layer 4 is strong.
またＦＲＰ層４と金属継手１との接合が、接着だけでは
なく、段１ｂのところで引掛ｐがあることにより、強固
であシ、このため、ＦＲＰパイプ２に対する捩りや軸方
向の引張力に対して十分な継手強度を有する。In addition, the connection between the FRP layer 4 and the metal joint 1 is strong not only by adhesion but also by the presence of the catch p at the step 1b. It has sufficient joint strength.

強用のＦＲＰ層５を設けると、より強固な継手構造が得
られる。As shown in FIG. 4, when the ten-stage metal joint 1b is sloped, the stress concentration at the second stage 1b is alleviated, so that a stronger joint structure can be achieved.゛Furthermore, if necessary, as shown in Fig. 5, a reinforcing FRP layer 5 can be provided on the outer peripheral surface of the FRP pipe 2 so as to correspond to the bonded part of the metal joint 1, to obtain a stronger joint structure. It will be done.
