The present invention pertains to a steel cage structure that is conveniently mounted, wherein a vertical steel bar is fixed to a frame at upper and lower ends thereof, and the frame is provided with steel cages that are connected to each other for convenient mounting and is formed in the shape of a circle or a polygon so as to make a column in various shapes. The steel cage structure is characterized in that: frame (10), which is formed in the shape of a circle or a polygon, is provided so as to be used as an end frame (30) and a connection frame (20); the frame (10) has a horizontal plate body section (11) and a vertical plate body section (12) such that the vertical plate body section (12) is perpendicularly fixed to the inside end of the horizontal plate body section (11); ribs (13) are fixed between the vertical plate body section (12) and the horizontal plate body section (11) at predetermined intervals; a plurality of screw grooves (14) are formed in the horizontal plate body section (11) at predetermined intervals such that the screw grooves (14) vertically penetrate the horizontal plate body section (11); a vertical steel bar (16) has screw sections (16-1) formed at upper and lower ends thereof and the end portions of the vertical steel bar (16) are inserted in the screw grooves (14) of the connection frame (30) so as to be coupled by nuts (18); hoops (17) are fixed outside the vertical steel bar (16) by binding wires (17-1) at predetermined intervals; and a welding section (16-2) is formed by welding in a state that the lower end of the vertical steel bar (16) is inserted in the screw groove (14) of the end frame (20) that is the frame (10) positioned at the front end of the base. |
