Producing method of steel column assembly for filling concrete and steel column assembly

摘要

The present invention relates to a manufacturing method of a concrete filling column assembly using a manufacturing frame and a binding frame for facilitating the production of a column by attaching the binding frame at a predetermined interval inside the column and joining the corner steel to form a column, To a column assembly produced thereby. A preferred embodiment of the present invention relates to a manufacturing method of a flat panel display, comprising the steps of: (A) forming a U-shaped cross-section frame having vertically arranged unit members vertically arranged at both ends of a horizontal member and a horizontal member, A step of fabricating a binding frame made of an octagonal edge shape and made of a straight material made of angles and spaced apart from each other by a predetermined distance in four directions and an inclined material configured to connect a straight material and a straight material adjacent to each other in an oblique direction, ; (B) fixing a thick plate mounting member having a predetermined height to each corner where the horizontal member and the vertical member of the fabricating frame meet; (C) fixing a center plate of the lower part of the fabricating frame and a thick plate to the upper part of the plate mounting part, respectively, and fixing them; (D) bonding the binding frame at regular intervals in the longitudinal direction of the thick plate; (E) joining a thick plate to a straight line above the binding frame; (F) a step of joining the corner steel, which is formed with a cross-section and both ends of which are bent inward to form a reinforcing portion, at an edge so as to connect the upper and lower plates; (G) rotating the binding frame to which the thick plate is bonded by 180 degrees, placing it in the interior of the fabric frame, placing the corner steel at the corners to connect the upper plate and the adjacent plates; And (H) completing the concrete filling column assembly by removing the fabrication frame.
