Non-synthetic arch rib for which steel and reinforced concrete were used and the arch bridge construction technique for which this was used

摘要

The present invention provides a non-synthetic arch rib composed of steel ribs and reinforced concrete to be used to construct an arch bridge using non-synthesized steel and reinforced concrete without attaching a shear connector to the steel for specific cases of mechanical behavior. And it aims to provide an arch bridge construction method using the same. Non-synthetic arch ribs composed of steel and reinforced concrete according to the present invention for achieving the above object is characterized in that the steel is coated with a certain thickness of the steel, the reinforcement in the concrete. In addition, the arch bridge construction method using a non-synthetic arch rib composed of steel and reinforced concrete according to the present invention for achieving the above object comprises the steps of manufacturing the formwork; Reinforcing steel bars in the formwork; Inserting and fixing steel in the center of the formwork; After placing and curing concrete in the formwork, demoulding the formwork to produce arch ribs; Hardening the arch ribs to the reinforcement girder, and assembling and installing a hanger vertically between the arch ribs and the reinforcement girder, characterized in that consisting of the step of constructing the arch bridge by introducing the initial tension to the hanger.
