Inner truss system, shape steel-steel pipe concrete cross column and method for constructing same
The invention discloses an inner truss system, a shape steel-steel pipe concrete cross column and a method for constructing the same. The shape steel-steel pipe concrete cross column comprises outer wrapping steel pipes, inner filled concrete and the inner truss system. The inner truss system comprises shape steel with a crossed transverse section, angle steel with an inverted-L-shaped transverse section, pressure sleeves and draw bars. The pressure sleeves are longitudinally arranged on web plates of the angle steel and the shape steel along a truss system, two ends of each draw bar are respectively fixedly connected with the corresponding pressure sleeve on the corresponding web plate of the shape steel and the corresponding pressure sleeve on the angle steel, and the angle steel is distributed to form quadrilaterals; the angle steel is fixedly connected with the outer wrapping steel pipes. The inner truss system, the shape steel-steel pipe concrete cross column and the method have the advantages that the bearing capacity and the shear capacity of column components can be improved by the steel pipes and the inner truss system, the ductility of the components can be obviously improved, and the anti-seismic capacity of structures can be enhanced; outer planar support effects can be realized by inner trusses for the web plates of the shape steel, accordingly, width-thickness ratios and height-thickness ratios of the web plates can be decreased, and the stability of the web plates can be improved.
