The present invention provides a deck coupling apparatus comprising: a tetragonal support plate in which a part of the lower surface thereof can come into contact with the upper surface of a lower support; a deck coupling part which is formed by compressing two sides of the support plate, and is piece-coupled in a manner that the upper surface thereof supports the lower surface of a deck; and a support coupling part which can be coupled to the lower support as a part of one end of the support plate extends to the outside in the plate surface direction, wherein the other end of the support plate has a cut part in which a certain area is inwardly cut. Thus, the present invention has the advantage of enabling construction of a curved section of a deck by enabling angle adjustable coupling.
