PURPOSE:To achieve reduction of labor and shortening of construction period at site by forming a floor for storage in an attic space into a panel so that the floor can be easily installed between the inner surfaces of opposed wall panels. CONSTITUTION:A floor panel 20 for storage in an attic space is constituted beforehand by connecting a framework 30 formed by assembling lateral and longitudinal core materials 31, 32, 33, 34, 35, 36 having dimensions nearly corresponding to the dimension between the inner surfaces of approximately opposed wall panels 11, 11 integrally with floor materials 21, 22, 23, 24 to be applied to the upper surface of the framework 30. Further, an opening 25 for a folding stair is formed to enter and leave the attic space. |
