FIXING STRUCTURE FOR A TRUSS GIRDER FOR A REINFORCED CONCRETE SLAB AND THE FIXING METHOD CAPABLE OF PREVENTING THE SEPARATION OF A TRUSS GIRDER BY FIXING A TRUSS GIRDER TO A DECK PLATE

摘要

PURPOSE: A fixing structure for a truss girder for a reinforced concrete slab is provided to prevent the separation of a truss girder by welding or riveting a lattice member of a truss girder to the lower part of a folding unit of a deck plate. CONSTITUTION: The fixing structure for a truss girder(60) for a reinforced concrete slab contains a lattice member(52) extended longitudinally by abutting on both sides of one upper chord(54) and a pair of lower chords(56) by turns, and a deck plate(80) provided with projections(82) formed at regular intervals to fix a truss girder(60) composed of a crank(55) joined/welded to the upper chord(54) and the lower chord(56) selectively. The projection(82) is folded to face each other to form a folding unit(83) for abutting closely to the lower part of the lattice member(52), and the inner top of the folding unit(83) and the base of the lattice member(52) are fixed by a welding unit(92) or a coupling unit(94).
