Abstract

PURPOSE:To close the end of a deck plate by simple work in closing the end of a deck plate of a concrete structure by press forming by using a punch and a lower die of specified structure. CONSTITUTION:A slant 11 is formed by pressing the end of crest of a deck plate 10 by using a punch provided with a side punch fixed to the base plate and a central punch that moves vertically at the center, and a lower die corresponding to the crest of the deck plate 10. An intermediate slant 13 and a ridge part 14 are pulled toward the slant 11 of the end of crest and bent to form crestlike ribs 15 on both sides of the slant 11. Then, the crestlike ribs 15 are pushed down toward the central punch 1 by pushing down the side punches 2 on both sides of the central punch 1. Then, they are folded to close the end of the deck plate 10.
