Title:
ANCHORAGE METHOD FOR COLUMN REINFORCEMENT IN COLUMN HEAD OF UPPERMOST FLOOR IN REINFORCED CONCRETE STRUCTURE
Document Type and Number:
Japanese Patent JP2713121
Kind Code:
B2
Abstract:
PURPOSE: To secure a sufficient anchored leaf column reinforcements and solve shortage of concrete filling in the panel zone by simplifying the arrangement of column reinforcements in the column head in the uppermost floor to ease jamming of reinforcements in the uppermost floor panel zone.
CONSTITUTION: When column reinforcements are extended up to the uppermost floor by welding column reinforcements at the upper ends of column reinforcements extended from the downfloor, reinforcements bent like a hair pin are used as the uppermost floor column reinforcements 1A-1D. These two legs are connected with butt-welding to a pair of existing column reinforcements 1 positioned in the diagonal direction in the horizontal section or the parallel direction thereto and the upper horizontal part of the uppermost floor column reinforcements are contained in the uppermost panel zone. With respect to the column reinforcements having no counterpart in a pair of two pieces to connect the hair pin type uppermost floor column reinforcements 1A-1D, the uppermost floor column reinforcements bent like a hook at the front end are connected with butt welding and the hook is contained in the upper most floor panel zone.
