Title:
EXECUTION OF COLUMN CONSTITUTION MEMBER
Document Type and Number:
Japanese Patent JP3263727
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To increase strength of a connection part and improve working efficiency and execution precision by locating a column constitution member in a pile hole after burying a casing in the underground and placing concrete in the excavated pile hole and integrally executing a pile and the column constitution member of a ground part.
SOLUTION: A casing 2 is buried in an underground, and a ground in the easing 2 is excavated down to a prescribed depth to form a pile hole 5 so as to insert a pile reinforcing bar cage. A frame 6 locating a column steel frame 10 being the column constitution member A of a ground part is installed upward of the casing 2, and after concrete 3 is placed in the pile hole 5, the column constitution member A prefabricating a column leg reinforcing cage 12 is hung down as the frame 6 is made a guide to bury the lower end in unhardened concrete 3 of a pile head part 4. Since a cast-in-place concrete pile 1 and the column constitution member A are integrally and continuously executed, ground case construction can be early performed, and shortness of a construction period and reduction of a construction cost can be contrived to improve working efficiency. In addition, since the column constitution member A is constructed as the frame 6 is made a guide, execution precision is improved.
