  • Connecting structure for steel frame columns and steel frame girders
    Patent number: 7874120
    Abstract: Sufficient yield strength is achieved against tensile, compressive and shearing forces working on steel frame columns and steel frame girders by using simply configured connective fittings to reduce costs and construction periods. For this purpose, a connective structure of highly rigid steel frame columns and steel frame girders formed by connecting steel frame columns and steel frame girders each having a web part and flange parts with connective fittings is provided. Each of the connective fittings has a bottom plate part and, on a surface of the bottom plate part, side plate parts which rise at a substantially right angle to the bottom plate part and have inserting areas extending farther than a tip of the bottom plate part in the state of rising at the substantially right angle.
