Title:
BAR REINFORCEMENT CEMENT SYSTEM STRUCTURE
Document Type and Number:
Japanese Patent JP2015028281
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a structure having large resistance force to external force such as tensile force without causing a crack, even if a method of introducing prestress is not adopted by arranging a PC steel material, in the structure of using a fiber-reinforced composition containing cement.SOLUTION: The bar reinforcement cement system structure 1 is formed by arranging an irregular-shaped reinforcement 3 in the fiber-reinforced composition 2 containing cement capable of revealing compressive strength of 100 N/mmor more. In the bar reinforcement cement system structure 1, a rate of the area (the gross area, when a plurality of irregular-shaped reinforcements 3 exist) of the irregular-shaped reinforcement 3 in the cross-sectional area of the bar reinforcement cement system structure 1, when cut in a vertical plane to the axis of the irregular-shaped reinforcement 3, is 0.03-20%.
