Document Type and Number:
Japanese Patent JP2015224496
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a grating and a manufacturing method thereof, for largely reducing a labor burden and work cost, and without imposing a stock space, inventory storage and management burden, by simply manufacturing a main member of a flat upper surface and a main member with slip resistance.SOLUTION: A plan view rectangular grating is formed by fixing an end plate 3 to respective side end surfaces 22 projecting in both-side lateral direction of a connection material 2, by fixing a side plate 4 to respective side end surfaces 12 projecting in both-side lateral direction of a main member 1, by crossing a band plate-like metallic main member 1 having an engaging object part 13 and mutually arranged in parallel at a constant pitch by vertically setting the band width direction and a slender band plate-like metallic connection material 2 having an engaging part 25 fitted to the engaging object part 13 in response to a pitch of the main member, at a right angle in a grating shape, and the main member 1 is formed by cutting out of a metallic plate material 5 by any one cutting processing among laser processing, plasma processing and water jet processing.
