1 is a perspective view showing a deck plate according to the present invention, Figure 2 is a cross-sectional view of FIG.

1 and 2, the deck plate 10 according to the present invention is coupled to the parent plate reinforcement cap plate 13 to the deck plate main body 11 to secure the continuity of the end, the deck plate main body 11 of The truss-type reinforcing bar 14 connects the flat portions 111 to close the ribs 121 opened in the width direction with the lateral distribution with the adjacent ribs, so that the ribs 121 that are opened and placed during the concrete pouring are formed. It prevents the lateral distortion of the plate 10 and effectively resists the external force acting (especially the bending moment). In addition, the open end surface is closed to secure the deck shape and the continuity of the end.

Further, as shown in FIGS. 1 and 16, the bending bending reinforcement plate 125 is integrally formed at both ends of the deck plate main body 11 in the longitudinal direction, thereby preventing penetration of the pouring concrete and closing the cross section, thereby increasing the strength further.

In the present invention, the deck plate body 11 has a flat portion 111 and two side surfaces 121a, 121a extending inclined from the flat portion 111, the two adjacent deck plate body (11, 11) end The coupling portion 121e is connected in the width direction (lateral direction) to form a cross-sectional shape having a plurality of open ribs 121 parallel to each other separated by the flat portion 111. The open rib 121 has a gap between the side surfaces 121a and 121a of the neighboring rib 121, and the gap may be wider than the width of the bottom surface 121b. Therefore, the opened rib 121 has a bottom surface 121b and both side surfaces 121a, and an upper surface between the flat portions 111 has an open structure.

The deck plate body 11 configured as described above may have a constant width and may be connected to each other by overlapping end portions of both sides in the width direction of the adjacent deck plate body 11. The bottom surface 121b constituting the rib 121 is formed with a dove tail groove 121c for coupling the hardware for installing the ceiling finishing material, and a dove tail rib 121d defining the dove tail groove 121c is formed. The vertically bisected end coupling portion 121e is used to overlap the side surfaces of the adjacent deck plate body 11. When the dove tail groove 121c is not formed in the bottom surface 121b of the rib 121, that is, when the end coupling portion 121e of the above-described form is not formed, the end bending process for the separate overlapping seam is performed. Such end bends can be made and are known in the art.

On the other hand, from above, the two adjacent deck plate bodies 11 having the flat portion 111 and the two side surfaces 121a and 121a extending obliquely from the flat portion 111 are formed in the width direction using the end coupling portion 121e.
