A corrugated composition plate is provided to install vertically a vertical plate of a reinforcement member and a reinforcement plate for horizontal reinforcement, thereby reducing the use amount of materials, easily manufacturing a product, and improving the mobility of concrete due to a plurality of ventilation holes and exhaust holes. A corrugated composition plate includes a plurality of outer ribs(23), a plurality of inner ribs(22), and an insertion hole. The outer ribs(23) protrude downward from an outer end portion of a reinforcement plate(20). The inner ribs(22) protrude downward from an inner peripheral surface of a ventilation hole(21). The insertion hole is formed with a predetermined interval between the outer ribs(23), and a reinforcement member is inserted into the insertion hole. A protrusion member, which is inserted into the ventilation hole of the vertical plate, is provided at the end portion of the outer rib of the reinforcement plate. |
