確保の容易さを満足させる接合方法、接合構造を如何に
実現するかが問題となる。However, if the steel pipe is used and the joining method by welding is adopted, there are the following problems. First, since water circulates inside the heat conduit, rusting is unavoidable, and stress corrosion cracking occurs particularly in the welded portion, and there is a problem in terms of durability. Secondly, since the steel pipe is heavy, it requires a lot of labor and equipment for construction, and is not easy to handle and transport. Thirdly, also in terms of construction accuracy, it was not easy to secure linearity by joining by welding. Therefore, it is conceivable to replace the steel pipe itself with another material, and as a candidate therefor, a heat conduit composed of GFRP, which is also excellent in strength, can be proposed, but in that case, it is possible to simplify the construction and secure the construction accuracy. The problem is how to realize a joining method and a joining structure that satisfy the easiness.

ＦＲＰ管から成る継手４を設ける。As shown in FIG. 1, two GFRP pipes 2 and 2 to which an annular seal material 1 is fixed are provided on the outer periphery of one end.
Each sealing material 1 has a tapered outer edge whose diameter gradually decreases toward the end of each GFRP tube 2. Separately from this, an annular protrusion 3 is provided on the inner periphery of the tubular center portion.
A joint 4 composed of an FRP pipe is provided.

外周との間に環状の密閉空間５が夫々形成される。Next, as shown in FIG. 2, one end of each of the two GFRP pipes 2, 2 is inserted into the joint 4 from both ends thereof, and the end portions of each of the GFRP pipes 2 are formed into an annular shape inside the joint 4. The sealing material 1 of each GFRP pipe 2 is pressed against each end of the joint 3 while being pressed against the protrusion 3. As a result, an annular closed space 5 is formed between the inner circumferences on both sides of the joint 3 and the outer circumferences of the GFRP pipes 2 facing each other.

The adhesive 8 is injected into each closed space 5 from the above to fill it as shown in FIG. 3, and at the same time, the air in the closed space 5 is discharged from each discharge port 7 provided on the outer periphery of the joint 4 to bond them. The agent 8 is solidified. As a result, an adhesive layer having a constant shape and thickness is formed.

Further, if unevenness 10 is provided on the outer peripheral surface of the end portion of the GFRP pipe 2 to be connected as shown in FIG. 4 and unevenness 11 is also provided on the inner peripheral surface of the joint 4, the bonding area of the adhesive is increased and the bonding force is increased. Is increased, resulting in a strong bond.
【００１４】なお上記実施例では継手４をＧＦＲＰ管と

きる。EFFECTS OF THE INVENTION In the method of joining GFRP pipes of the present invention, since a sealed space for injecting an adhesive is formed, it is simply G
Compared with the case where the adhesive is applied to the inner and outer surfaces of the FRP tube, there is no uneven coating, and a fixed amount of the adhesive may be injected. Therefore, it is possible to form an adhesive layer having a certain amount and a certain shape in a short time without requiring skill, and surely attach the adhesive layer to the GFRP pipe and the joint. Further, the thickness of the adhesive layer can be easily adjusted by selecting the diameter of the joint for the GFRP pipe to be connected.

Bubbles in the closed space can be expelled, and an adhesive layer of uniform quality can be formed. Further, it is not necessary to process the end of the GFRP pipe to be connected.

る。Further, in the joint structure of the present invention, the joint has an annular ridge on the inner periphery of the central portion thereof, and the end of the inserted GFRP pipe is pressed against the annular ridge, so that the adhesive injected into the closed space is bonded. There is no risk of the agent entering the GFRP tube where it joins. Further, since the fixed closed space is filled with the adhesive and solidified, the adhesive layer formed by these is constant, and the joining of the two GFRP tubes is extremely reliable.
