COMPOSITE DECK STRUCTURE HAVING ENGINEERED LUMBER AND CONCRETE SLAB

摘要

The present invention relates to composite deck structure having civil engineering wood and a concrete slab, comprising: an engineered lumber formed by stacking a plurality of laminated timbers to be used as a structural material of a building; a bending steel plate of at least one part of which is buried in a longitudinal direction of the civil engineering wood therein; and a concrete slab formed by pouring concrete in front of an upper part of the engineered lumber. This composite deck structure is able to prevent a person from slipping on a concrete boundary surface by combining curved steel plates of various shapes with civil engineering wood laminated with a plurality of glued timbers; secures a combining performance and ductility of wood and concrete; allows a lower part of a concrete slab to act as a fire resistant covering material; and additionally forms a new composite member by combining curved steel plates which are simply curved to reinforce insufficient resultant yield strength of the civil engineering wood, and secures higher resultant yield strength than a conventional span-band type wood by changing the shape of its connector located between the wood and concrete, into an L-shape, T-shape or an asymmetric H-shape. Consequently, this composite deck structure is able to be featured as a major component of a high-rise and long-span composite building.
