The present invention relates to a demolding deck capable of detaching a sheathing board after a truss girder and the sheathing board is integrally assembled and concrete is cured. More specifically, the present invention relates to a spacer which provides sheath thickness to a truss girder while easily and conveniently being assembled and facilitating demolding of the sheathing board, and a demolding deck using the same. According to an appropriate embodiment of the present invention, a channel-buried type spacer includes a support block formed of a main block body, and a plurality of leg blocks configured to be protruding from both ends and a central end of the main block body toward a lower portion of the main block body in predetermined lengths, and including a coupling groove having a screw thread formed at a lower portion of the leg blocks protruding from the central end; and a burying channel formed of a horizontal board horizontally buried in the main block body, and a vertical board vertically extended from both surfaces of the horizontal board at partial regions of the both ends of the horizontal board to be protruded toward an upper portion of the main block body. |
