PURPOSE:To raise the efficiency of operations by using a simple structure of a movable form device by connecting a stop lever to detachably support by bolts buried in a concrete structure and the working lever of an elevator to the form. CONSTITUTION:Through holes for bolts 3 are formed in the lower end portions of stop levers 2, 2 fixed to the back of a form 1, and an elevator 4 consisting of a base 4a, a slide support lever 4b, a power cylinder 4c, and a rod or vertically movable operating lever 4f is made up. The base 4a of the elevator 4 attached to the form 1 is fixed with bolts 3 to a concrete body A. The cylinder 4c is operated, the rod 4f is raised, the support lever 4b is moved upwards, while the form 1 is moved up to a given height. The stop levers 2 are fixed to the concrete body A to fix the form 1. The base 4a is removed and raised by the cylinder 4c, and fixed to the concrete body A, and then concrete is placed up to the height of the form 1. The same operations are repeated thereafter. |
