する。(Function) As described above, in the present invention, since the Y-shaped reinforcing piece is integrally embedded across each of the T-shaped pieces of the fiber-reinforced composite material, the tensile force applied to the composite material is reduced. Bending forces are dispersed by the Y-shaped reinforcing piece, reducing peel forces generated in the T-shaped integral part.

されている。 The Y-shaped reinforcing piece 4 is made of titanium alloy with a plate thickness of 1 mm, for example, and is connected to a vertical part 4a embedded in the piece 2 that intersects at right angles at the T-shaped intersection part 1a.
A pair of inclined legs 4b, 4b buried in the intersection part 1a are branched out at an intersection angle of 60°, and at the tip of each leg part 4b there is a part that intersects horizontally at the T-shaped intersection part 1a. A horizontal portion 4c embedded in the piece 3 extends.

率）となる。 Since the embodiment shown in the figure is constructed as described above, the peeling force P acting on the fiber-reinforced composite material 1 is applied to both legs 4b of the Y-shaped reinforcing piece 4 by P'=1/2P (cos θ/ 2) It is dispersed as -1 , and the peeling force acting on the T-shaped intersection 1a is reduced. (Reference to Figure 4) In the figure, p indicates the stress at the T-shaped intersection 1a, and the stress at the intersection is calculated assuming that it has the same strain rate as the Y-shaped reinforcing piece 4. Therefore, the stress at the T-shaped intersection is the stress of the Y-shaped reinforcing piece×(elastic modulus of the T-shaped intersection/elastic modulus of the Y-shaped reinforcing piece).

る。 The stress reduction effect of the Y-shaped reinforcing piece 4 at the intersection 1a increases as the rigidity of the reinforcing piece 4 increases. If the required strength is not satisfied, the horizontal portion 4c of the Y-shaped reinforcing piece 4 and the piece 3 are connected with bolts 6. (3rd
(See figure) (Effects of the invention) In the present invention, as described above, by embedding a Y-shaped reinforcing piece across each of the intersecting parts in the T-shaped integral intersection part of the fiber reinforced composite material, the above-mentioned The stress at the intersection is reduced, which in turn increases the strength of the composite, and prevents separation between fiber layers of the composite due to peeling forces acting on the composite.
