STRUCTURE OF CONTINUOUSLY CONNECTING PRECAST CONCRETE PANEL AND HONEYCOMB GIRDER STEEL BEAM AND CONTINUOUS CONNECTION METHOD

摘要

PURPOSE: Structure for continuously connecting a precast concrete panel to a honeycomb girder steel beam and a continuous connecting method are provided to manage and maintain conveniently by increasing the span and reducing moment with assembling beams successively, and to improve comfortableness in traveling on the bridge by relieving tensile stress to the upper concrete slab with a tendon. CONSTITUTION: Two composite precast concrete panel beams(100) are placed at right and left sides of a shoe plate(201), and the shoe plate is combined with a sole plate(202). A joint connecting bottom plate is inserted between a web(101) of a steel beam and a concrete pouring part(50), and contacted to the lower part of the web by a height adjusting plate. A flange connection part(20) is formed by mounting upper and lower flange connecting plates(203,206) to a flange(104) with bolting, and a web connection part(30) is formed by combining the web with web connecting plates through bolting. The lower part of the web is welded into the upper part of the joint connecting bottom plate, and the joint connecting bottom plate is combined with a steel reinforcement bar. Non-shrinkage concrete(205) is poured in the form around the concrete pouring part, and an anchorage(111) is installed in a lower connecting plate(120). A tendon(113) is fastened to resist moment to the honeycomb girder connection part.
