Claims

[Scope of utility model registration request]

Overlapping peripheral plates 1a, 1a of adjacent cosiclete formworks 1, 1
A connecting portion 2A formed at the inner end of a flat plate-shaped joint member 2 for configuring a concrete separator that can be inserted and fixed in between, and an intermediate bar 5 for configuring a concrete separator.
The connecting portion 5A formed at the end of the connecting portion 5A has a conical or substantially conical peripheral wall portion 4A, and the large diameter side opening peripheral edge 4a of the peripheral wall portion 4A.
An internal space 4 of a truncated conical or substantially conical end treatment member 4 which is fitted onto the intermediate bar 5 and held in contact with the inner surfaces 1a, la of the cosiclete formworks 1, 1.
A pin for insertion joining and pulling out and separation in B, which has a non-penetrating head 3A at one end with respect to both the connecting parts 2A and 5A, of a pin shaft part 3B, which has a small part on the distal end side with respect to the head 3A. Both the connecting portions 2A are located near the
, 5A is provided with an impenetrable portion 3C, and a pin sticking-out retaining portion 3D is formed between the impenetrable portion 3C and the head 3A. .
