GRATING RECEIVING FRAME FIXING DOUBLE-SIDED MAGNET SHEET PRODUCT IN MANUFACTURING PROCESS OF SIDE DITCH FOR ROAD, AND METHOD OF MANUFACTURING SIDE DITCH FOR ROAD USING THE PRODUCT

摘要

PROBLEM TO BE SOLVED: To reduce time, a labor cost and a cost by eliminating nut fastening work and postprocessing performed for fixing a receiving frame in a manufacturing process of a side ditch for a road with the grating receiving frame.;SOLUTION: When fixing the grating receiving frame and a metallic form of the side ditch for the road, clearance between the receiving frame and the metallic form can be eliminated by adopting a technique of sandwiching a resilient double-sided magnet sheet instead of nut fastening. Thus, quality of a finished product of the side ditch for the road can be improved, nut installing- removing work in the manufacturing process of the side ditch for the road can be eliminated, and invading concrete removing work to the clearance required for the postprocessing can be eliminated, that are the purposes of fixzation, thereby contributing to cost reduction.;COPYRIGHT: (C)2001,JPO
