Document Type and Number:
WIPO Patent Application WO/2021/187226
Kind Code:
A1
Abstract:
[Problem] To provide a concrete form panel which, during installation of concrete form panels for a building/civil engineering framework construction, allows a fastener to be stably fixed to a separator, and which can be assembled efficiently without using a specific spacer. [Solution] An opening of a separator is formed as a tongue part which can be raised in a U-shaped quadrangular shape or parallelogram shape. The tongue part is formed such that when the tongue part is vertically raised on a surface side with respect to a recess-side bottom surface of a rib, along a folding line on the base side connected to the recess-side bottom surface of the rib part, a front-end edge surface of the raised portion of the tongue part and a protrusion-side flat surface of the rib are in flush positional relationship. When an external thread side of the separator is passed through the opening formed by raising the tongue part and the external thread is screwed with an internal thread of a fastener, both the front-end edge surface of the tongue part and the protrusion side-flat surface of the rib part are joined with a flange part of the fastener.
