<p>The present invention relates to a jig for installing a horizontal pole of a ladder type-structure where multiple horizontal poles are continuously and vertically installed. The jig for installing a horizontal pole of a ladder type-structure supports horizontal poles to be installed on an upper part of the structure by using a lower horizontal pole to allow a horizontal connection and weld the horizontal poles to be stably performed and easily matches horizontal angles and vertical angles between the horizontal poles on up and down sides. The jig for installing a horizontal pole of a ladder type-structure wherein horizontal poles are installed on upper and lower sides, respectively, comprises: a lower end support part supporting a horizontal pole to be supported, which is positioned on a lower side; at least two lift shaft parts erected on an upper surface of the lower end support part, where heights of the lift shaft parts can be vertically adjusted; and at least two upper end support parts formed on ends of upper parts of the lift shaft parts to support the horizontal pole to be installed, which is positioned on an upper side thereof.</p> |
