Japanese Patent JP3326223
Kind Code:
B2
Abstract:
PURPOSE:To eliminate the need for assembling a form in a narrow place and to promote work efficiency by laminating a foaming polystyrene block in a hollow section in a reinforced concrete strut, and using it as the form and a scaffold. CONSTITUTION:A foaming polystyrene block is laminated in the hollow section of a strut surrounded by vertical reinforcements 2. It is used for a scaffold in the case of execution and, at the same time, it is also used for an inside form. After that, a horizontal reinforcement 5 is arranged on the upper surface of a highest layer of the foaming polystyrene block. Then, an outside form is executed at a specific interval. After that, concrete is placed between the layer of the foaming polystyrene block and outside form. The uplift of the foaming polystyrene block in the case of the compaction of concrete is controlled by the horizontal reinforcement 5. While repeating state of work mentioned above, the reinforced concrete strut is extended up to the required height. According to the constitution, the installation and removal of the scaffold are not required, and a construction period can be reduced.
