The present invention provides a deck plate system having continuous haunched end portions using a cap plate, the system having deck plates, configured to be haunched, of which the end portions are bent, closed and reinforced, and the deck plates being applied to the deck plate system having the continuous end portions so as to reduce positive moment, thereby eliminating the need for the installation of shores during construction, forming a very efficient cross section after combining, effectively resisting the gaping and transverse torsion of the deck plates during construction, and ensuring more increased bending strength. One preferred embodiment of the present invention comprises: a deck plate body having a predetermined width in a cross sectional shape having a plurality of open ribs separated, in parallel to each other, by a flat part; a negative moment reinforcing cap plate comprising a cover part closing the open ribs at both end portions of the deck plate body in the longitudinal direction and a coupling part horizontally extended from both end portions of the cover part to be settled on and coupled to the flat part, and provided at positions spaced at predetermined distances from the end portion of the deck plate body; and truss-type prefabricated reinforcing bars provided in the width direction of the deck plate body so as to connect the flat parts, wherein end-reinforcing bent plates are integrally formed at both longitudinal end portions of the deck plate body, the end-reinforcing bent plates comprising: top-reinforcing bent parts formed by downwardly bending a predetermined section from the end portion of the flat part at a predetermined angle in order to prevent the infiltration of poured concrete and close and reinforce the cross section; and side-reinforcing bent parts formed by bending the lateral sides of each rib to be overlapped on the top-reinforcing bent parts, a dovetail groove is formed on the bottom surface forming the open ribs, and end coupling parts having the shape in which dovetail ribs defining the dovetail groove are vertically divided in half are used to lap-splice both end portions of the neighboring deck plates in the width direction. |
