Abstract

PURPOSE:To fit a branch pipe at a desired position of a composite pipe by attaching a prepreg mat in the periphery of a branch hole of a main pipe, and making a flange part of a branch pipe to abut on the prepreg mat, and fastening the flange part of the branch pipe against the main pipe for fixation with a presser tool. CONSTITUTION:A prepreg mat 3 is interposed between a flange part 51 of a branch pipe 1 and a branch hole 22 of a main pipe 2, and the branch pipe 1 and the main pipe 2 are fastened for fixation by a presser tool 4. The branch pipe 1 comprises a pipe main frame 10 made of the heat reversible resin, and the outer peripheral surface thereof is covered with a fiber reinforced layer 5. The main pipe 2 comprises a pipe main frame 20 made of the heat reversible resin, and the outer surface thereof is covered with a fiber reinforced layer 5. The prepreg mat 3 is made of the quality as same as the fiber reinforced layer 5, and a hole is provided in the central part thereof. The presser tool 4 consists of an annular part 41 and a band part 42. As a result, branch pipes can be connected easily and securely even if after forming a main pipe or after the pipe arranging.

一体化することとなる。That is, as shown in FIG. 6, this connection method involves inserting a branch pipe member d, which is provided with a flange C on the outside of one end of the branch pipe, onto the inner surface layer formed around the core mold a. Then, a reinforced resin molding material e is wound around the inner layer and the flange C to form an outer layer f, and a portion of the inner layer where the branch pipe of the branch pipe member d contacts is opened to form a branch pipe. The inner surface layer F and the outer surface layer F are integrally cured. In the branch structure thus obtained, the branch pipe member d is
Since the flange C is inserted, the flange C is embedded in the inner surface layer, and the inner surface layer and the branch pipe member d are firmly integrated.

If another branch pipe member d is required at a different position on the inner surface layer, there is an inconvenience that the branch pipe member d cannot be added. Furthermore, since the process of forming the inner and outer layers f and the process of attaching the branch pipe member d are performed at the same time, there is an inconvenience that the process becomes complicated. Furthermore, since the flange C is embedded in the inner surface layer, there is a problem in that if the flange C is installed in the wrong position, it cannot be repaired.

1 has a hole approximately the same diameter as the outer diameter of the branch pipe 1 provided in the center of the disc-shaped main body. By inserting the branch pipe 1 through this hole, the annular portion 41 comes into contact with the flange portion 51. The surface that comes into contact with the flange portion 51, that is, the inner surface of the annular portion 41, is made of a material with good mold releasability in consideration of the case where it comes into contact with uncured resin. For example, metals, plastics, etc. that have been given a plating finish, a mirror finish, a gel coat finish, etc. are preferable. Further, the band portions 42 are connected from opposite positions of the annular portion 41, go around the main pipe 2, and can be tightened together.

Although the annular shape is interposed between the peripheral edge of the branch hole 22 and the flange 51 of the branch pipe 1, the present invention is not limited to this, and as shown in FIG. The present invention can also be carried out using a prepreg mat 30 whose inner circumferential portion has two layers 31 and 32 so as to envelop it. In this case, since the flange portion 51 is covered and bonded, stronger adhesive strength can be obtained.
