PREFABRICATED LIGHTWEIGHT GIRDERS FOR BRIDGE AND BRIDGE CONSTRUCTION METHOD USING SAME

摘要

The present invention relates to a structure of a bridge which enables a concrete girder, lightweight and prefabricated, to simply be assembled and rapidly constructed in an actual construction spot. To this end, the lightweight girder is formed of a first vertical unit and a second vertical unit spaced from each other, and a horizontal unit connecting the upper parts of the first and the second vertical units to each other to form a space unit with an opened lower part; is provided with a cogged joint on a lower part of a side surface of the first vertical unit, and provided with a hooking groove corresponding to the cogged joint on a lower part of a side surface of the second vertical unit wherein a width of the cogged joint is formed greater than that of the hooking groove; and has a plurality of traverse beams installed between the first vertical unit and the second vertical unit.;COPYRIGHT KIPO 2016
