COMPLEX CONCRETE METAL SEAL STIFFENER FOR METAL PLATE ARCH TYPE STRUCTURE

摘要

PPROBLEM TO BE SOLVED: To provide a waved metal arch type structure reinforced by complex concrete. PSOLUTION: This waved metal arch type structure reinforced by the complex concrete includes (i) a first set of molded wave type metal plates (78) which are mutually connected and (ii) a second series of molded wave type metal plate (24) mutually connected so as to be overlapped on the first mutually connected plate set. The series of the second plate and the first plate set specify a plurality of continuous sealed cavities (80) which are filled with concrete (86) and extend laterally and individually. The inner surfaces of the cavities of the first and the second plates have a means (96) which provides shearing adhesion on the concrete and a metal interface to provide individual bending beams crossing the arch. This structure provides a positive/negative bending resistance relative to applied load and a resistance relative to bending and a combination of axle loads. PCOPYRIGHT: (C)2007,JPO&INPIT
