<；P>；PROBLEM TO BE SOLVED: To provide a framed panel of an inexpensive structure, for easily constructing the roof of an agricultural greenhouse. <；P>；SOLUTION: In the flat plate-like framed panel 1, sticking a flexible sheet 3 of the same outline is stuck to a rigid frame body 2 of regular hexagon, reinforcing the flexible sheet 3 by three reinforcing tapes 4 fixed to the flexible sheet 3 so as to bridge each pair of opposite angles placed to be symmetrical about the point of the regular polygon, and fixing both ends of each of the reinforcing tapes 4 to angles 3A-3F of the rigid frame body 2. The framed panel 1 is put in a pulled state as a whole by pulling both ends of each of the reinforcing tapes 4 by a pulling wire 6 and retaining each of the reinforcing tapes 4 in a tense state. The roof surface of an agricultural greenhouse is easily constructed by using the framed panel 1, and the roof surface hardly causing looseness, damage and break and having high durability is obtained. <；P>；COPYRIGHT: (C)2011,JPO&INPIT
