Claims

[Scope of utility model registration request]

A washer frame 3 that can be attached to the back of a thick timber 2 that is in contact with the back of the concrete form 1, and a washer frame 3 that is held through the connection hole 4 of the washer frame 3 and has one end locked to the concrete form 1. Possible tie rod 5 and
A wedge is driven into a wedge hole 6 formed on the other end side of the tie rod 5 at the back of the washer frame 3, thereby tightening and fixing the concrete form 1 to the end piece 2 via the tie rod 5 and the washer frame 3. 7, at least one of the left and right guide plates 3a, 3b facing each other at an interval approximately equal to the thickness of the wedge 7 for guiding wedge driving in the washer frame 3 protrudes toward the other. At the same time, the wedge 7 on the side corresponding to the projection 8 is formed.
The projection 8 is formed on at least one side surface 7a, 7b of the wedge along the driving direction of the wedge between the inside of the narrow end 7c and the inside of the wide end 7d.
A grooved line 9 is formed to slide into the groove, and the distance D from the starting end 9a of the grooved line 9 to the tip 7c of the wedge 7 is equal to the distance D from the connecting hole 4 of the washer frame 3 to the protrusion 8 of the guide plate. The concrete mold is characterized in that the projections 8 are configured to hold the wedges 7 through grooves 9 fitted therein so as to be unable to separate from the washer frame 3.
