Inner truss type steel tube concrete L-shaped column and construction method thereof
The invention discloses an inner truss type steel tube concrete L-shaped column and a construction method thereof. The inner truss type steel tube concrete L-shaped column comprises a wrapping steel tube, filling concrete and an inner truss; the inner truss comprises T-shaped steel, inner truss subunits and T-shaped steel web lacing bars; the inner truss subunits are formed by welding the T-shaped steel; the T-shaped steel web lacing bars are longitudinally welded in a T-shaped steel web and the inner truss subunits along the T-shaped steel in a stacked manner; the T-shaped steel and the inner truss subunits are positioned at edges and corners of a quadrangle; the cross section of the wrapping steel tube is inversely L-shaped or n-shaped; and the wrapping steel tube is fixedly welded with flange plates of the T-shaped steel. The inner truss is tensioned at a corner of a special-shaped steel tube, so that effective width of a steel plate is reduced, a fulcrum is provided for deformation of the steel plate out of a plane, anti-unsteady capability of the steel plate can be improved, a hooping effect of the column is improved, and the bearing capacity of a steel tube concrete special-shaped column is improved obviously.
