<P>PROBLEM TO BE SOLVED: To provide a precast concrete poured casted aluminum capable of using a casted aluminum as a formwork for precast concrete to make the casted aluminum into an exterior wall. <P>SOLUTION: A precast concrete poured casted aluminum 10 comprises: a casted aluminum 12 made of iron coated with aluminum to be used as a formwork for precast concrete; and a concrete 14 to be filled in the casted aluminum 12. The precast concrete poured casted aluminum 10 is equipped with: a heat buffer material 16 placed between the casted aluminum 12 and the concrete 14 to buffer a difference of heat expansion rate between the casted aluminum 12 and the concrete 14; and a connection mechanism 18 absorbing a difference in displacement due to a the difference of the heat expansion rate between the casted aluminum 12 and the concrete 14 to connect the casted aluminum 12 and the concrete 14. <P>COPYRIGHT: (C)2012,JPO&INPIT |
