Title:
REINFORCING BAR ASSEMBLY
Document Type and Number:
Japanese Patent JP3074282
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a rigid foundation concrete structure having high support stability by connecting a variable-shape frame section expandable to the outside direction of a reinforcing bar frame body to the lower end side in the longitudinal direction of the reinforcing bar frame body.
SOLUTION: A hole expanded at the lower bottom section is formed in the ground. A reinforcing bar assembly is inserted into this hole with a variable- shape frame section 2 located on the lower side. The frame section 2 constituting the reinforcing bar assembly is connected to the lower end side in the longitudinal direction of a reinforcing bar frame body 1, and it can be expanded to the outside direction of the reinforcing bar frame body 1. When the lower end section of the frame section 2 reaches the lower bottom section of the hole, the frame section 2 is expanded at the lower bottom section of the hole by the tare weight of the reinforcing bar assembly, and the reinforcing bar assembly can be stretched around in the whole hole. When concrete is poured into the hole, concrete is filled around the reinforcing bar assembly, and reinforcing bars are stretched around in the whole concrete. A rigid foundation concrete structure having high support stability can be obtained.
