Strongback attachment system for concrete panel tilt-up construction |
摘要 |
A fastener system for temporarily securing a reinforcing beam or the like to a poured concrete structural member includes an anchor to be set in poured concrete with an exposed handle portion free of said concrete, and a shaft with a slotted end for receiving the handle portion. A spring loaded pin in the slot retains the handle portion in interlocking engagement with the shaft. An opposite end of the shaft secures a strongback beam to the concrete structure.
