The present invention relates to a column structure and, more specifically, to a column structure with rigidity in respect to a load of a horizontal beam including: a post of which a cross sectional area becomes larger to a lower side and perpendicularly arranged on the ground; the horizontal beam joined to the post and where a sign lamp or a road sign is installed; and a coupling means coupling the post and the horizontal beam. The durability of the post is improved by forming a reinforcing surface protruding from the post to a front surface where the horizontal beam is installed to allow a lateral surface of the post where the horizontal beam is joined to obtain higher rigidity in comparison with outer surfaces. Thus, an effect of preventing the deflection of the post due to the load of the horizontal beam is obtained. |
