Abstract
A resin bonded glass fiber grating adhesively bonded together in unitary construction to form a lightweight, high strength industrial grating, which may include a non-skid elastomer surface and the capability to be rolled up for storage and a method of constructing the same.
Claims17
A method of manufacturing a grating constructed of resin bonded fibers, comprising the steps of:
- extending a plurality of dowels through registered apertures in a plurality of I-elements, said apertures being substantially the same size as the cross-sectional size of the dowels;
- applying to the dowels adjacent to the I-elements a heat setting adhesive which has a long pot life of about an hour or more at ambient temperature and which becomes highly fluid for several seconds and then heat sets in several seconds when heated to a flow temperature of about 100.degree. F. or more;
- heating the dowel and I-element intersection areas, including the adhesive, to said predetermined flow temperature to thereby cause the adhesive to become highly fluid thereby wetting the surface of the dowel and flowing by capillary action into the interior of the aperture in the I-element and thereafter heat setting to bond the dowel to the I-element.
