DECK PLATE

摘要

PROBLEM TO BE SOLVED: To provide a deck plate capable of preventing cracking of a thermal insulation material by dispersing pressure applied to the thermal insulation material even when the thermal insulation material is placed on the deck plate, endurable against a load such as weight of a worker and snow in construction work, and capable of facilitating work for laying a thermal insulation plate and a waterproof sheet, while making the most of a characteristic of the deck plate having a strong structure. SOLUTION: This deck plate 10a has a folded-plate material 11a of alternately regularly arranging a plurality of projection parts and recessed part by bending a metallic plate, and is provided with a recessed part cover 12a for covering the recessed parts. A cover upper part plane 14a of the recessed part cover 12a is formed so as to become the same plane as an upper flange 13a1and an upper flange 13a2of the projection parts.
