Steel structure of irregular building structure Twist construction method

摘要

The present invention relates to a twist construction method for a steel structure of an atypical building structure. The present invention includes: a molding preparation step of preparing a molding in accordance with the shape of a steel structure; a molding placement step of placing a position fixture in accordance with the shape of the steel structure and then placing a molding to be bent on the position fixture; a molding processing step of fixing one end of the molding seated on the position fixture and performing bending while heating the curved portion; and a molding assembly step of moving the molding bent through the molding processing step to an installation place, painting the molding, and then welding the molding and joining the molding through a fastener to form a steel structure. According to the twist construction method for a steel structure of an atypical building structure of the present invention, a circular pipe, a plate material, a plate material welding pipe, and the like constituting an atypical frame forming the skeleton or the exterior of an architectural structure can be processed into a desired shape. In addition, it is possible to improve installation quality by coping closely with installation angles and installation tolerances, and it is possible to shorten the construction period by improving installation convenience.
