<p>A panel body capable of being assembled easily using the spiral wire and using spiral wire having a high rigidity and an excellent workability and impact resistance, where the wires of a specified outside diameter are twisted spirally at a specified lead and pitch so that the spiral diameter is approximately twice the outside diameter and the shape of the crest part is identical to that of the root part and each root part is positioned on the outside of a spiral center so as to form a number of spiral wires, the spiral wires are disposed on a first fixing frame having first fixing bars connected at specified intervals between the frame members opposed to each other at a specified interval so that the first fixing bars are engaged with the root parts of the spiral wires positioned on one surface side of the spiral wires, and second fixing bars are installed between the frame members of a second fixing frame at specified intervals and, when the first fixing frame is fixed to the second fixing frame, the second fixing bars are engaged with the root parts of the spiral wires positioned on the other surface side of the spiral wires in association with the first fixing bars so as to hold the spiral wires.</p> |
