Reinforcement of the constructs with a fiber-reinforced plastic plate

摘要

PURPOSE:To prevent gap from developing and, in addition, easily discharge excess adhesive by a method wherein entrapped air is easily prevented from leaving, even when the air is entrapped between the adhesive, which is applied onto the surfaces of the beam and slab of concrete structure as well as other parts to be reinforced in various structures, and fiber reinforced plastic plate. CONSTITUTION:Prepreg 7 is produced by feeding matrix resin such as thermosetting resin to long carbon fibers, which are continuously fed onto continuously fed lower film having the predetermined width, and impregnating the carbon fibers with the matrix resin under heat and pressure with rolls or the like. Uncured prepregs 7 are laminated to one another. In addition, a plurality of through holes 8 are bored flatwise. Next, after each through hole 8 is filled with soft filling material or clayey material such as putty, sealant or the like so as to plug the through hole 8, the laminated prepregs 7 are heated at 130-180 deg.C for setting. After setting, by removing the clayey material, which fills the through hole 8, a fiber reinforced plastic plate 6 having through holes 8 is obtained.
