The present invention relates to an elbow assembly structure controlled at omnidirectional angles capable of allowing bent parts to be widely used regardless of installation purposes and locations. The elbow assembly structure comprises: a hollow body (10) formed into one shape among′+′,′inverse T′,′Y′, and′L′shapes; connection holes (20) extended from the body in all directions at independent positions, and communicating with the hollow body; and multiple connection members (30) formed into a laterally symmetric fan shape to form a path on a curved surface and successively fixed on the end of the connection holes to make sections extended from the connection holes at various curvatures. Protrusion parts (35) are extended from one side of the connection members (30) to be introduced into the connection holes (20) or the close connection members. At this time, laid l-shaped fitting pieces (36) are arranged on the protrusion parts at regular intervals. Also, one or more E-shaped fixing pieces (37, 21) in which the close fitting pieces (36) are fitted by rotating at a specific direction protrude from the other side of the connection members or the inner surface of the connection holes.
