PURPOSE: A truss assembly is provided to securely keep a position even though a fixing blot receives lots of load while the bolt is fixed to a truss bar. CONSTITUTION: A truss assembly comprises a first truss bar(500a), a fixing bolt(400), a second truss bar(500b), and a fixing angle. The first truss bar is formed into a tetragon shape with a hollow space inside and comprises an opening(510) in a front side along a longitudinal direction. The fixing bolt is installed to be moved along the opening. The fixing bolt comprises a head and screw body where a nut is fixed to. The second truss bar is installed to be intercross with the first truss bar. The fixing angle is fixed to the fixing bolt, thereby supporting a decoration panel for an external wall of a building. |
