ABSTRACT:
There is provided a clamp for concrete forms which has improved durability compared with a conventional P-clamp, and can withstand vibrations necessarily produced by a vibrator when the concrete is placed. This clamp for concrete forms comprises a substantially U-shaped clamp body which rivets end parts of a pair of L-shaped clamp arms to each other so as to be rotatable and holds a connection part of the concrete forms, and a clamp lever body which presses one clamp arm toward the other clamp arm to press both clamp arms against each other by riveting ends of a pair of arm parts with respect to the other clamp arm so as to be rotatable, and rotates them toward the clamp arm, and engages an opening part formed between the pair of arm parts with the L-shaped bent shoulder part of the other clamp arm.
