PURPOSE:To shorten the time of operation by making easier the delivery and fabrication of a formwork even in working site inconveniently situated by a method in which the periphery of a caged frame is covered with a film and then with a netting and concrete is placed into the frame. CONSTITUTION:The height of a cross-shaped iron tower supporter cleat 3 is adjusted by cobble stones 4 and a concrete block 5, the legs 1 of an iron tower are attached, and leveling concrete 7 is placed. Four one-split rings 8 are fixed to an arm 1 and 12 iron pipes 9 are fixed to the ring 8 at equal intervals to complete a caged frame. The periphery of the caged frame is covered with a soft and adhesive vinyl chloride stretched film 11 and then with a polyester- bonded netting 12 covered with vinyl chlorde. Concrete is placed into the formwork thus formed and hardened, the hole is back-filled with soil, and the concrete foundation structure is completed. |
