Document Type and Number:
Japanese Patent JP3252571
Kind Code:
B2
Abstract:
PURPOSE: To facilitate execution containing mounting and dismantling, and to improve a finished surface remarkably by using a paper core panel in place of forms at the time of the execution of the placing stop of concrete, the execution of an irregular surface, the execution of dehydating forms, etc.
CONSTITUTION: Surface boards 2, 2 are bonded with both surfaces of a paper core 1, and coated with waterproof agents 3, 3 continuing waterproofness for a fixed time, and dismantling members 4 are stuck on the circumferential side faces of the waterproof agents. Corrugated board sheets 11, 11 are bonded to the surfaces as the precedently placed sides of paper core panels 13 for concrete placing stop, and the surfaces of the sheets 11, 11 are coated with a setting retarder for delaying the setting of precedently placed concrete and the paper core panels 13 are mounted at the position of execution.
