BEARING STRUCTURE OF STRING BEAM

PROBLEM TO BE SOLVED: To realize a reasonably and economically light-weighted string beam structure which does not hinder the characteristics of the string beam structure. SOLUTION: A bearing part 10 comprises a stainless plate 16 glued on a lower surface of a base plate 13 welded to an end part of the string beam 8, a top plate 18 fixed onto a lower frame 14 by the intermediary of a mortar member 19, a sliding plate 15 having a smaller width L than that of the base plate 13 and being interposed between the stainless plate 16 and the top plate 18, anchor bolts 20, ... protruding from the lower frame 14 and penetrating long holes 23, ... formed in the base plate 13, and nuts 22 being fastened by the intermediary of washers 21 in a state of leaving an allowance Dz. The long holes 23, ... formed in the base plate 13 are long in a span direction of the string beam 8. The base plate 13 is slidable on the sliding plate 15 in the span direction. A stopper 17 abutting the base plate 13 is placed beside the base plate 13 on the top plate 18 at a predetermined interval Dx. COPYRIGHT: (C)2007,JPO&INPIT
