To solve problems in a construction joint method of conventional technology which requires partition plates formed with reinforcement insertion holes in positions corresponding to reinforcements to be arranged, requires the partition plates adapted to the size of a column, a beam or the like to be jointed, requires to bore the reinforcement insertion holes adjusted to the positions of arranged reinforcements, and further requires a large number of partition plates.
A joint bar with a construction joint lath is formed by embedding a lath end 3, along a longitudinal direction, in a concrete bar 1 of suitable length with a quadrangular cross section of square, rectangular or trapezoidal shape formed of concrete not lower in strength than placed concrete so that the embedded end 3 of the lath 2 is in the embedded state so as not to project from the concrete bar 1.
