PURPOSE: A hammer is provided to easily connect concrete form assembly panels by forming a groove into which a connecting pin in the assembly panel is inserted. CONSTITUTION: In a hammer(10) composed of a head(11) and a handle(12), a pin groove(13) is formed at the head. A connecting pin in an assembly panel is inserted into the pin groove. A circular groove(25) is formed at the outer circumference of the head. An inner groove(14) is formed from the lower end of the handle to the upper end. A cap is attached/detached to/from the inner groove, and has a screwdriver groove in the lower end. A coupling unit couples the cap with the handle.
