JIG FOR TESTING STEEL LATTICE GIRDER OF SHOTCRETE LINING, AND TEST METHOD FOR LATTICE GIRDER USING SUCH JIG

摘要

PURPOSE: A jig for testing steel lattice girders and a loading test method for steel lattice girders using the jig are provided to stably support second and third bars of a triangle steel lattice girder from sides. CONSTITUTION: A jig for testing steel lattice girders comprises a main body(20) and a side fixing member(30). The main body provides a space(S) in which a triangle steel lattice girder(1) is placed in the shape of inverted triangle. The side fixing member is installed on the top of the main body and transformed in the transverse direction to fix a side of the triangle steel lattice girder.
