LATTICE GIRDER FOR STRENGTHENING A BENDING LOAD, A MAXIMUM LOAD, AND BENDING INTENSITY

摘要

PURPOSE: A lattice girder is provided to be easily manufactured with a simple structure change and to reinforce a load bearing power.;CONSTITUTION: A lattice girder comprises a first bar(10), a second bar(20), multiple unit connectors(5), and an auxiliary connector(3). The first bar is located at an upper vertex of a triangle, and a second bar is arranged in parallel at a lower vertex of the triangle. The unit connectors and the auxiliary connector are welded to a third bar. The connector comprises a first bar center welding unit, a second bar welding unit, a third bar welding unit, and a first bar side welding unit. The first bar center welding unit touches the lower surface of the first bar with a line. The second bar welding unit and the third bar welding unit are connected at both ends of the center welding unit by being downwardly extended. The first bar side welding unit is vertically extended from the end of the second bar welding unit and the third welding unit to the upper side, and is welded by being connected to the lower surface of the first bar.;COPYRIGHT KIPO 2013
