Title:
COMPOSITE BEAM
Document Type and Number:
WIPO Patent Application WO/2021/059410
Kind Code:
A1
Abstract:
Provided is a composite beam that uses a vertically asymmetric steel H-beam and that can be suitably used in floor structures for buildings such that if this composite beam is adopted for the floor structure of a building, deflection in the vertically asymmetric steel H-beam is suppressed during the construction process for the floor structure, and as a result, total deflection of the floor structure is suppressed when in use. The composite beam has a steel H-beam and a composite slab that is formed so as to configure a structure integrated with the steel H-beam by pouring concrete on a deck plate placed on the top face of the steel H-beam. The ratio At/Ab of the cross-sectional area At of the top flange on the steel H-beam to the cross-sectional area Ab of the bottom flange is 0.7/1.3 to less than 1.0, where the deck plate mountain side flange width is greater than or equal to the valley side flange width and the height of the deck plate is 25-100 mm.
