Abstract:
1. A deck-to-girder connection structure connecting a precast or prefabricated deck to a girder, comprising: at least one rod shaped elevation adjustor inserted through the deck to support the deck spaced apart from an upper surface of the girder at a predetermined interval, so as to allow a length of the rod shaped elevation adjustor projected toward an upper face of the girder to be adjusted and to allow the precast deck to be supported; and at least one shear connector inserted through the deck, a lower portion of the shear connector extending toward the upper surface of the girder, an upper portion of the shear connector being fastened by at least one fastener, wherein, when the deck is supported at a predetermined elevation spaced apart from the upper surface of the girder by the elevation adjustor after the deck is placed on the girder, a filler material is filled in a space between the girder and the deck to cause the lower portions of the elevation adjustor and the shear connector to be covered by the filler material; and the fastener is fastened to the shear connector while pressing the deck downward; and wherein the deck is a deck made from fiber reinforced plastics having a multi-cellular cross-section in a transverse direction; at least one anchor block, which has a cross-section corresponding to a single-cellular cross-section, is inserted and fitted in the fiber reinforced plastic deck to cause the shear connector to be fitted through the fiber reinforced plastic deck and the anchor block; and the elevation adjustor has an outer surface formed with a thread, and at least one through-hole of the fiber reinforced plastic deck for accepting an elevation adjustor has an inner surface formed with a thread corresponding to the thread of the outer surface of the elevation adjustor, so that the elevation adjustor is screwed with and inserted into the fiber reinforced plastic deck.
