FORM FOR MANUFACTURING CONCRETE PRODUCT

摘要

PROBLEM TO BE SOLVED: To solve the problem that utility in the case of repeating use is enhanced by using a hinge in an inner form for facilitating mold release in a form for manufacturing a concrete product but the durability of the hinge lowers when the weight of a part of the inner form is applied to the hinge. SOLUTION: The form for manufacturing the concrete product is constituted so that the inner form is arranged in an outer form and concrete is cast in the gap between the inner form and the outer form to manufacture the concrete product. The inner form 100 is composed of an inner form main body 110 and the bottom plate frame part 120 attached to the inner form main body 110 detachably and equipped with a bottom plate forming surface 120a for forming the bottom plate of the concrete product and the inner form main body 110 is equipped with a non-deformable fixed frame part 111, the movable frame part 113 movably connected to the fixed frame part 111 through a deformable connection member 112 and a regulation mechanism 114 for regulating the stress caused in the connection member 112 by the movable frame part 113.
