摘要

PROBLEM TO BE SOLVED: To provide a step joining member of reinforcement trusses for constructing a deck having a step, and to provide a stepped reinforcement truss.;SOLUTION: The step joining member 10 has the same width as an inner width w of the reinforcement trusses 80, 85 to be connected together, and consists of a channel steel 11 having a hole 18 formed at the center of a web 17 thereof, a first steel plate 15 blocking one end of the channel steel 11, and a second steel plate 16 fixed to the channel steel at a location that makes contact with a lower peripheral portion of the hole 18 or in the vicinity of the same, in a manner blocking a channel portion of the channel steel 11 in parallel with the first steel plate 15. Then top reinforcements 81, 86 of the respective reinforcement trusses and bottom reinforcements 82, 83, 87, 88 of the same are welded to the the step joining member 10, to thereby join the two reinforcement trusses together across the step.;COPYRIGHT: (C)2004,JPO&NCIPI
