かった。For example, in Japanese Utility Model Laid-Open No. 63-147397, 2
In the case of joining the carbon fiber reinforced resin composite prisms to each other in a substantially L-shape, the end faces of the prisms are obliquely cut and joined together, and two reinforcing members are utilized by utilizing that the surface of the prism is a flat surface. Although they are arranged so as to straddle the prism, they are joined to each other in an L shape, so that the lateral beam cannot be joined to any position of the side beam. Further, since the prisms are notched diagonally, the rigidity and strength are lowered, and therefore reinforcement is required.However, in the case of a tubular body having a curved surface that is not composed only of a flat surface such as a cylindrical shape or an elliptical shape other than the prismatic shape. In some cases, the reinforcing member using a flat surface could not be used.

替えは困難である。Further, in Japanese Patent Laid-Open No. 3-231063, a cylindrical cross beam is inserted into a side beam having a box-shaped cross section made of a fiber-reinforced resin composite material and bonded with an adhesive. In order to secure it, the inside of the honeycomb core is filled with a resin and used for the joining portion, and the structure is complicated and the weight increases, which hinders the weight reduction. Therefore, in the present invention, as in Japanese Patent Application No. 5-104910, a joint surface having a curvature substantially equal to the outer surface of the fiber-reinforced resin tubular body which is the joint object is provided for each corresponding joint object, and the joint surface is The members of the tubular body that compose the above are arranged according to the arrangement of the article to be joined and integrated so that one tube body of the article to be joined can penetrate, but since it is also adhesive joining, replacement of parts It is difficult.

Fiber reinforced resin composite material prepreg is used to pierce through holes, bolts, and other holes to pierce the fiber reinforced resin composite material hollow beam with the other fiber reinforced resin composite material beam. A cross-bonding method of a fiber-reinforced resin composite hollow beam which allows conventional design technology and replaces parts can be obtained by sandwiching the sandwich and connecting the sandwiched pieces using bolts, rivets and the like. In the fiber reinforced resin composite material, the strength around the hole was weak and bolt joining could not be used for high strength parts, but the one reinforced with the fiber reinforced resin composite material in advance and sandwiched with the lightweight bonding member on the inner and outer surfaces was bolted. Since it is tightened using a rivet or the like, the force is transmitted by the surface pressure, so that it can be applied to a high strength portion.

も多くなる。For these fiber-reinforced resin composite beams, the so-called filament winding method, in which reinforcing fibers are passed through a liquid resin, wound around a metal cored bar, heated and then the cored bar is pulled out, is most commonly known. However, a sheet winding method, a pultrusion molding method, a hand lay-up molding method, or the like may be used. The hollow beam to be perforated at the time of molding is reinforced at the perforated portion with a fiber reinforced resin composite material prepreg of about 1 to 4 mm. Reinforcement thickness is 1
If it is less than mm, the compressive strength is weak and the tightening force cannot be obtained. If it is more than 4 mm, the bolt length is required to be long and the weight is heavy.

る。As described above, according to the present invention, since it is difficult to weld or bolt-join a fiber-reinforced resin composite material, the conventional method of relying on adhesive bonding is generally used for a metal, but the fiber-reinforced resin composite material has a higher hole-surrounding strength. It was possible to make bolt connections that were not used because they were weak. For this reason, it becomes possible to apply fiber-reinforced resin composite materials to high-strength parts of building structural materials and high-speed railway vehicles.By using this method, the strength design cultivated with conventional metals can be used, and parts can be freely replaced. Can be implemented.
