Being the FRP make soundproof wall which possesses

摘要

PROBLEM TO BE SOLVED: To provide a self-standing sound-proof wall made of FRP having high strength and rigidity, less deteriorated and durable even when used in an outdoor environment, preventing the adhesion surface between an FRP cylindrical body and an FRP skin layer from being separated even in an outdoor use environment with large temperature difference, having the strength and rigidity expected in design by the integration of two members to each other, eliminating the intrusion of rainwater into the mounting part, and eliminating the risk of corrosion such as rusting.;SOLUTION: This FRP sound-proof wall comprises an FRP sound-proof panel part and a mounting part having a depth of 5 to 20% of the height of the sound-proof panel part. The mounting part comprises a reinforcement member formed of an FRP cylindrical body enclosing a foam plastic.;COPYRIGHT: (C)2007,JPO&INPIT
