COMBINATION STRUCTURE OF FENCE

摘要

PURPOSE: A coupling structure of a fence is provided to fix a horizontal pipe to a post pipe simply without welding work and to reinforce the impact force of a post against external impact. CONSTITUTION: A coupling structure of a fence contains: a post pipe(10) provided with insertion holes(12a,12b) formed on right and left sides having an inside space(11), and a concave groove(13) formed in the longitudinal direction of the center of the backside; a cover member(20) mounted to the concave groove of the post pipe and coupled to form the unified side with the outside of the post pipe; a horizontal pipe(30) penetrating the post pipe through the insertion hole; and a reinforcement member(40) coupled to reinforcement ribs(14,15) to increase the stiffening force of the post against external impact and formed in the inside space of the post pipe.
