STEEL PLATE STRUCTURE AND STEEL PLATE CONCRETE WALL

摘要

PURPOSE: A steel plate structure and a steel plate concrete wall are provided to easily discharge water vapor pressure existed inside of concrete, and to reduce the thickness of the wall and the steel plate. CONSTITUTION: A steel plate structure(10) comprises a pair of steel plates(12), struts(16), and perforated pipes(17). The steel plates are each other faced, and separated to form a certain space. The struts maintain a separation distance of the steel plates. The perforated pipes are located inside of the space, and extended from one end of the space to the other end. Multiple holes are formed in the perforated pipes.
