Method for producing precast concrete member and joint key connecting tool

摘要

PROBLEM TO BE SOLVED: To enable favorable setting of a joint key for joining both joint end faces to each PCa (precast concrete) member to shorten a construction schedule.SOLUTION: A method for production of PCa member includes connecting a first female key 41 installed to a first joint end face formwork 52 for embedding in a first PCa member 11, and a second female key 42 installed to a second joint end face formwork 62 for embedding in a second PCa member 12 by a connection tool 80 having at both end parts, the pin inserting parts 81, 82 to be inserted in respective key holes 81a, 82a to be connected before concrete placing. Thereby, the central axis K1 of a key hole 41a in the first female key 41 and that K2 of a key hole 42a in the second female key 42 can be made straight-line, and difficulty on the joint operation of the first and second PCa members 11 and 12 is avoided to shorten a construction schedule.SELECTED DRAWING: Figure 14C
