To provide a pressing fixture for concrete forms, which easily and efficiently constructs a haunch portion of a concrete structure, to thereby reduce construction costs.

The pressing fixture A is provided for the concrete forms F, F for use in constructing the haunch portion of the concrete structure. According to the pressing fixture A, a rotation center O is set at its central portion, and a rotary fixture 18 is arranged at the rotation center such that its shaft portions 19a, 19b extend rightward and leftward from the rotation center, followed by fixing angle adjusters 1, 10 to the shaft portions 19a, 19b, respectively. Then, one of the angle adjusters 1 is rotated along a rotation radius R1 of the other angle adjuster 10, and both the angle adjusters 1, 10 are connected together at a predetermined location, followed by tilting one of the shaft portions 19a, 19b of the rotary fixture 18.
