Curing Method for Joint between Precast Concrete Block with In-situ Concrete

摘要

PURPOSE: A connection concrete construction method between precast concrete blocks is provided to stably connect the precast concrete blocks by efficiently curing connection concrete in a connection unit of the precast concrete blocks with steam. CONSTITUTION: A mold plate fixing frame is installed by crossing connection spaces between precast concrete blocks(10) which are adjacent to each other. A mold plate is hung by a fixing vertical rod, and connection concrete is placed on the mold plate. The mold plate, the fixing vertical rod, and the mold plate fixing frame are removed after connection concrete is cured. A curing steam pipe is installed on the upper surface and the lower surface of the connection concrete, and a dome-shaped curing cover covers the connection concrete. Steam is injected into the vertical end of the curing steam pipe, and fills the inside of the curing cover in order to cure the connection concrete.
