The invention relates to a steel-wood concrete combination column and a construction method thereof, which are used for solving the technical problem that the
mechanical property and the subsequent use performance of a wood core combination column are obviously influenced due to direct hydraulic jacking of a wood core into a steel
pipe. The wood core is located in the steel
pipe, the
diameter of the wood core is smaller than the inner
diameter of the steel
pipe, the wood core is formed by splicing a plurality of vertical battens in the horizontal direction, arc-shaped grooves are formed in the ends, close to the center of the wood core, of the vertical battens, the arc-shaped grooves of the vertical battens are spliced to form a cylindrical jacking cavity, the inner pipe is coaxially inserted into the jacking cavity, and a plurality of long holes are evenly distributed in the pipe wall of the inner pipe. Levers are hinged to the interiors of the long holes respectively, one ends of the levers are located in the inner pipe, the other ends of the levers penetrate through the long holes to be hinged to jacking blocks, the jacking blocks are located between the inner pipe and the
cavity wall of the jacking cavity, the
cam shaft is coaxially inserted into the inner pipe, a plurality of protruding parts are arranged in the circumferential direction of the
cam shaft, and the protruding parts drive the levers to rotate by rotating the
cam shaft. And the supporting blocks are driven to tightly abut against the
cavity wall of the supporting cavity, so that the vertical battens tightly abut against the inner wall of the steel pipe outwards in the radial direction.
