Concrete structures construction methods and concrete stress distributed systems and concrete stress dispersion structure

摘要

And it is an object of the invention is to provide a concrete structure construction method and the concrete stress distributed systems and capable of preventing the concrete stress dispersion structure cracks with a simple structure of providing a plurality of at intervals in the concrete reinforcing rod-like stiffener stress distributed collar . Has a concrete reinforcing rod-like stiffener 1a, and stress dispersion brim 3 provided in the vertical direction from the circumferential surface of the concrete reinforcing steel rod-like 1a, this stress dispersion collar 3, length of the concrete reinforcing steel rod-like 1a It is a concrete stress dispersion structure 7a which is characterized by multiple provided at intervals in a direction.
