Title:
CRACK-INDUCING JOINT AND JOINTER FOR FORMING THE SAME
Document Type and Number:
Japanese Patent JP2015052217
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To secure a required covering thickness concerning second rebars or steel materials, without providing an overhanging portion, when forming crack-inducing joints perpendicular to the second rebars or the steel materials in a concrete structure with the second rebars or the steel materials embedded in first rebars and outside of the first rebars.SOLUTION: Crack-inducing joints (22) of the present invention are formed in a concrete structure (10) with second rebars (20) or steel materials embedded in first rebars (18) and outside of the first rebars, and are perpendicular to the second rebars or the steel materials. The joints include first bottom parts (26) for defining a required covering thickness (D1) between the first rebars, and second bottom parts (28) that are the second bottom part (28) ranging in the first bottom parts, and defining a required covering thickness (D2) between the second rebars or the steel materials. The joint depth (B) in the second bottom parts is smaller than the joint depth (A) in the first bottom parts.
