Title:
DOUBLE STEEL TUBE CONCRETE BEAM-COLUMN NODE WITH BUILT-IN FRP RIB CONNECTING APPARATUS AND INSTALLATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/011759
Kind Code:
A1
Abstract:
The present invention relates to the field of building structures; the double steel tube concrete beam-column node with a built-in FRP rib connecting apparatus of the present invention comprises a double steel tube column, an I-beam, a node connecting member, an inner support member, and an outer ring plate; the double steel tube column comprises an inner steel tube and an outer steel tube; the node connecting member comprises a connecting inner tube and a connecting outer sleeve, the connecting inner tube and the connecting outer sleeve both being round steel tubes; the inner support member is a columnar structure, bolt holes being evenly distributed along the circumference at both ends thereof; the outer ring plate comprises a horizontal part and a ring-shaped part perpendicular to one another; upper and lower double steel tube columns are connected by means of node connecting members and inner support members, both ends of the inner support member respectively being inserted into the upper and lower inner steel tubes, and the FRP rib passing in sequence through the ring-shaped part, the outer steel tube, the connecting inner tube, and the inner steel tube and then being fixed in the bolt hole of the inner support member. The present invention uses the excellent tensile properties and anti-fatigue load capability of the FRP rib to effectively improve the anti-seismic energy dissipation capability of the node and enhance the safety and bearing capability of the structure.
