Document Type and Number:
WIPO Patent Application WO/2023/195292
Kind Code:
A1
Abstract:
In order to simplify vertical joint construction between steel frame members to shorten construction time and reduce the cost required for construction, this steel frame member is used in a composite structure comprising concrete and the steel frame member disposed inside the concrete, wherein an anchoring steel sheet embedded by the concrete is provided to at least one end of the steel frame member. The anchoring steel sheet is provided to the inner peripheral side or outer peripheral side of the steel frame member. A protrusion is formed on at least a portion of the surface of the steel frame member. In a composite structure comprising concrete and the steel frame member disposed inside the concrete, a joint structure connecting a first steel frame member and a second steel frame member in the axial direction of the composite structure is provided with a first anchoring steel sheet on an end of the first steel frame member, and at least one among the outer surface and inner surface of the second steel frame member is disposed along the first anchoring steel sheet.
