PRECAST FORMWORK STRUCTURE

摘要

A precast form structure is provided to combine concrete to precast forms stably by providing shearing projections inside the precast forms. A precast form structure comprises precast forms(10) and steel bars(12). The precast form has a hole at center for concrete and shearing projections(15). The shearing projection is formed on the inner surface of the precast form to support the concrete. The steel bars interconnect the precast forms. Some of the steel bars are fixed to the forms at the top. Other of the steel bars are fixed to the precast forms at the bottom.
