A COLUMN CAP FOR PERMANENT BEAM FORM, AND A CONSTRUCTION METHOD USING THE COLUMN CAP

摘要

PURPOSE: An underground structure constructing method using a column cap is provided to assemble PC(Precast Concrete) member which is manufactured in a factory, a metal permanent beam form, and a column cap on work site, and place concrete. CONSTITUTION: A permanent beam form(400) is installed at a PC column(100). A column cap(200) is installed at the head portion of the PC column(100). The column cap(200) includes a rectangular plate-shaped lower frame(210), a rectangular plate-shaped upper frame(220), and a plate-shaped blocking frame(230). The plate-shaped lower frame(210) is laid on the upper portion of the PC column(100). The plate-shaped blocking frame(230) connects the plate-shaped lower frame(210) and plate-shaped upper frame(220). A beam settling surface is formed on the plate-shaped lower frame(210) in order to settle the permanent beam form(400).
