Abstract: The present invention relates to an apparatus for constructing an exterior panel for an outer wall of a building, and particularly, to an apparatus for constructing an exterior panel for an outer wall of a building, comprising: a plurality of first brackets fastened by respective anchor bolts arranged at a predetermined interval on a side surface of a slab or on the wall of the building such that the first brackets are equidistantly arranged at a predetermined interval in a vertical direction on the side surface of the slab or on the wall of the building; a plurality of square-shaped exterior panel installation rods each of which has a front surface with a central line along which a plurality of elongated bolt holes are formed at a predetermined interval in a vertical direction, wherein each of the exterior panel installation rods is vertically arranged between at least two of the first brackets and welded to an installation rod fixing piece of each of the first brackets; a plurality of second brackets fastened at a predetermined interval onto the respective front surfaces of the exterior panel installation rods by first bolts and first nuts coupled to the bolts, wherein a head of each of the first bolts has a shorter axial directional width smaller than the shorter axial width of the elongated bolt hole of the exterior panel installation rod, and a longer axial directional width larger than the shorter axial width of the elongated bolt hole such that the first bolt gets caught at the elongated bolt hole; and exterior panel fixing pieces each of which has an outer end equipped with a fixing pin inserted into a fixing hole penetrating through upper and lower surface of the exterior panel, and has an inner end fastened at the end of a horizontal support piece of the second bracket by the second bolt and the second nut so as to support the exterior panel, wherein each of the exterior panel fixing pieces is fastened integrally to the exterior panel installation rod at the state where the exterior panel is thus-supported. The exterior panel installation rod fixed at the corner of a building, from among the plurality of exterior panel installation rods, has a plurality of elongated bolt holes formed vertically, at a predetermined interval, in one of both side surfaces of the exterior panel installation rod along the central line of the side surface. According to the present invention, the necessity of using a horizontal beam and a reinforcement plate for fixing a vertical beam which might otherwise be used in conventional apparatuses is completely eliminated to thereby significantly reduce costs for constructing an outer wall using an exterior panel, significantly reducing the gap between the wall of a building and the exterior panel, remarkably improving work stability, and drastically shortening a construction period. In addition, the exterior panel installation rod of the present invention is square-shaped, and therefore, the exterior panel installation rod is prevented from being twisted by the weight of an exterior panel and the like, to thereby maintain the stability and aesthetic enhancement of the constructed exterior panel over a long period of time. Further, exterior panels can be installed at both sides of a single exterior panel installation rod at the corner of the building, without using an additional support, a vertical beam or the like, thereby constructing exterior panels in a simple and inexpensive manner, and remarkably improving workability.
