<p>PURPOSE:To prevent cracks generated around holes for clamping when a structure made of a fiber-reinforced resin (FRP) is connected to another body by clamping the structure with a pin, a bolt, etc. CONSTITUTION:A connecting section in a structure made of FRPs is covered with a cap 3 made of a thin metal, holes 3b penetrated through the cap 3 and the structure are bored, and pins, bolts, etc., are inserted into the holes 3b and the structure and the cap are clamped, thus dispersing stress applied around the holes 3b, then preventing the generation of cracks. When a notch section 3a is formed at the end section of the cap 3 made of the metal at that time, stress is dispersed effectively, thus acquiring a suitable result.</p> |
