<p>The present invention relates to an assembling lattice girder mainly applied to civil engineering or a building construction field, such as a tunnel, a vinyl house, a frame, a steel structure, etc. The assembling lattice girder can simplify a coupling structure between a stand bar and steel bars, wherein the steel bars are spaced apart at a predetermined distance, and can increase workability and productivity, and reduce production costs. The assembling lattice girder comprises: a plurality of first and second steel bars; a stand bar maintaining a gap between the steel bars; and a fixing means for coupling the steel bars and the stand bar. The stand bar is a three-dimensional single closed curve, and has an 8-shape connecting the first and second steel bars. The first steel bar in the middle of the stand bar is coupled on an upper surface of a first coupling part, and the second steel bars on both sides of the stand bar are coupled on lower surfaces of second coupling parts. The coupling portions between the first and second coupling parts and the steel bars are fastened by U-shaped first and second fastening bands.</p> |
