JOINT STRUCTURE OF STEEL-MADE CURBSTONE-CUM-DRAINAGE DITCH UNIT

摘要

PROBLEM TO BE SOLVED: To solve the problem that the joint structure has a difficult point in working because of joining the flat part of a constant width of a sealing packing and a magnetic sheet on the outer periphery not only between end faces but also continuously connected and adjoined.;SOLUTION: In the joint structure, the sealing packing is mounted between the opposite water passage part end faces of the adjacent steel-made curbstone- cum-drainage ditch unit, pairs of tightening plates are fixed in the neighborhood of both the ends, a tightening fitting is attached to the tightening plate, and the adjacent steel-made curbstone-cum-drainage ditch units are press bonded to each other by tightening it.;COPYRIGHT: (C)2002,JPO
