<p>PROBLEM TO BE SOLVED: To halve its manufacturing number and the storage number, by providing a reinforcement edge crowning cap made to correspond to a projection dimension of two ways.SOLUTION: The reinforcement edge crowning cap 1 is provided for crowning vertical reinforcement edges X1 and X2 of crossing reinforcements S1 and S2, and has the vertical reinforcement insertion depths D1 and D2 of long-short two ways up to the inner bottom 2b of an insertion-fitting hole 2 for seating vertical reinforcement end surfaces Xa and Xb from respective end surfaces 3a and 3b in an insertion-fitting state to the insertion-fitting hole 2 of the vertical reinforcement edges X1 and X2 by forming the end surfaces 3a and 3b of upper-lower two stages having a predetermined step difference in one diameter direction in an opening part 2a of the insertion-fitting hole 2 of the vertical reinforcement edges X1 and X2, and can be used thereby to two kinds of crossing reinforcements S1 and S2 having projection dimensions T1 and T2 corresponding to the vertical reinforcement insertion depths D1 and D2 of such the two ways.</p> |
