FORM FOR MANUFACTURING BLOCK FOR ARCH STRUCTURE, AND MANUFACTURING METHOD OF BLOCK ASSEMBLY FOR ARCH STRUCTURE

PURPOSE: A mold device of an arch block for forming an arch structure and a manufacturing method of a block assembly unit for forming the arch structure using the same are provided to rapidly manufacture the many numbers of the arch blocks as a same shape by easily controlling a shape of the arch block. CONSTITUTION: A mold device(1) of an arch block for forming an arch structure comprises a bottom mold panel(10), a vertical surface slope form panel(20), a lateral surface form panel(30), and a slope movement control member(40). The slope movement control member moves the vertical surface slope form panel in a vertical direction and controls a slope. The slope movement control member comprises a slope connection panel, a slope expansion rod, a movement member, and a bottom rail member. A position of the slope connection panel and the lateral surface form panel and an inclination angle are controlled due to the movement of the movement member and the expansion of the slope expansion rod.
