STRUCTURE OF JOINING STEEL-CONCRETE COMBINED FLOOR PANEL TO ITS UNIT STEEL SKELETON

摘要

PROBLEM TO BE SOLVED: To provide a structure of joining a steel-concrete combined floor panel to its unit steel skeletons, allowing easy construction and preventing cracking resulting in corrosive deterioration without causing the shortage in filling a concrete. SOLUTION: The unit steel skeletons 20A of the floor panel 20 are constructed with grooved-steel joint reinforcing beams 30 directed sideways to open to the side and fixed to the upper face of a bottom steel plate 21 at predetermined intervals approximately perpendicularly to a bridge shaft. The adjacent unit steel skeletons 20A are joined with a plurality of fastening mechanisms 40 provided at predetermined intervals along a joint line 20B. The fastening mechanisms fasten fastening plates erected on the joint edges of the bottom steel plate 21 and having a preset width in the direction perpendicular to the bridge shaft with fastening bolts.
