Abstract

PURPOSE: To simplify a prestress introduction work, by arranging a trussed assembly reinforcing steel and a prestress introducing steel in parallel up and down in a form and placing concrete in said form under the condition in which a tension is added to said steel.
CONSTITUTION: A side form and a tension device for prestress introducing tension steel are arranged at the cut face of a prestressed concrete beam of semi-finished product on a form 1 for manufacturing said beam, while prestress introducing tension steel 3 is arranged in said form. Then, a trussed assembly reinforcing steel 4 made by connecting upper and lower stringers 4a, 4b each other through a lattice steel 4c by means of welding, said upper and lower stringers 4a, 4b being as double arranged reinforcing steel, is vertically fixed in said form 1 above said tension steel 3 parallel therewith. After that, said tension steel 3 is tensioned according to the required amount of prestress and concrete is then placed in said form 1.
