Title:
METHOD OF REINFORCING FLAT SLAB AGAINST SHEAR
Document Type and Number:
Japanese Patent JP3916226
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method of reinforcing a flat slab against shear capable of easily carrying out bar arrangement work without interfering an upper end bar and a lower end bar with each other by approximately horizontally arranging a reinforcing bar against shear consisting of reinforcement and spiral reinforcement (or hoop) between the upper end bar and the lower end bar of the flat slab and progressively increasing shear proof strength (punching fracture proof strength) in the vicinity of a joint section between the flat slab and a column.
SOLUTION: A reinforcement bar against shear 8 having a height coming into contact with the upper end bar and the lower end bar between the upper end bar 4 of the flat slab 1 supported on the column and the lower end bar 5, is constituted by rolling the outer circumference of a plurality of parallel vertical reinforcing bars with the spiral reinforcement bar 7 or the hoop and has a length so as to sufficiently resist shear force, and it is approximately horizontally set by the arrangement crossing the shear fracture surface assumed as the flat slab with the column 10 as the center.
