<P>PROBLEM TO BE SOLVED: To provide a prefabricated wire net which can be folded for hand-held transportation to a mountain-ringed region or a river area, easily connected to simply construct a rhombic wire net, and allows an upper end spike and a lower end turn-back for preventing approach to be simply constructed. <P>SOLUTION: A plurality of isometric zigzag spiral bars 1 are combined, allowing both ends to be aligned. The both ends of the zigzag spiral bars 1 are provided with rings 5 and 5 to which axes are respectively inserted to form a rhombic wire net 3 having an approximately rectangle shape. A plurality of the rhombic wire nets 3 are arranged for connection through combining the rings 5 in a direction of the zigzag spiral bars 1. An axis 4 is inserted through the combined rings 5 and 5 to connect the rhombic wire nets 3 and 3 which are arranged at both sides of the axis 4 and foldable around the axis 4 to form a wire net unit 3'. <P>COPYRIGHT: (C)2012,JPO&INPIT |
