<p><P>PROBLEM TO BE SOLVED: To provide a stair equipped with a truss structural body having high flexibility of arrangement of lattice materials and capable of arranging lattice materials in always keeping a harmony in spite of the magnitude of gradient of the stair. <P>SOLUTION: The truss structural body T1 is constituted of an upper chord member U having a plurality of upper chord node members 1 arranged at regular intervals, a lower chord member L having a plurality of lower chord node members 2 arranged at regular intervals and a plurality of lattice materials 30 arranged between the upper chord member U and the lower chord members L. A connecting bolt 33 on one end side of the lattice material 30 is screwed to a bolt insertion hole of each lower chord node member 2, and a tread S is fixed to the upper chord node member 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
