The present invention relates to a cable tray connecting device, and more specifically, to a vertical type-cable tray connecting device having a simple structure to improve the coupling strength between the main body, upper connection part and lower connection part. The cable tray connection device comprises: an embedded main body; a hinge shaft pin; and a pair of upper extended members. The embedded main body has a pair of short width-walls and a pair of long width-walls, which face each other, and is embedded in a bottom slab, thereby forming a cable through passage in a vertical direction. Also, the embedded main body has hinge axial holes formed on both ends of the upper end of each long-width walls, the hinge axial holes formed along a hinge axial line in parallel with the short width walls. A hinge axial pin passes through the hinge axial holes. The upper extended members are installed on an upper end of the embedded main body to be in opposite to each other in such a manner where the upper extending members can be rotated between an extended position extended height-wise of the embedded main body and a folded position folded in a transverse direction with respect to the direction of the height. Moreover, each upper extending member has a hinge part formed on one end thereof, the hinge part having an axial pin through hole corresponding to the hinge axial holes. |
