Bridge floor Hantzsch's application manner

摘要

PROBLEM TO BE SOLVED: To provide a method for constructing bridge floor haunch in which a haunched part can be simply and rationally formed when it is required.;SOLUTION: A stud bolt 2 is fitted onto a steel girder 1. A support plate 3 is set on the stud bolt so as to correspond to the level of a bridge floor bottom face. Side plates 4 are detachably attached at the contour positions of the haunch. A space truss 5 with a provisional concrete form is laid on the upper face of the support plate 3. After laying it, the space trusses 5 are connected by a U-shaped rod 6. Concrete is placed in the welded reinforcements forming a truss to form a haunch together with the bridge floor. After the concrete is cured, the side plates 4 are removed in a disassembling process of forms.;COPYRIGHT: (C)2001,JPO
