An electric cable tray structure for a building includes a steel bar(3), a tray(40), a wire inserting rod(20), and a middle supporting body(10). The steel bar(3) is fixed on a ceiling slab to fix the middle supporting body(10). The tray(40) supports the wire inserting rod(20). Both ends of the tray(40) is inserted into a tray inserting hole(13) of the middle supporting body(10). The wire inserting rod(20) is connected by a wire inserting rod connection unit(30). Each of bolt units(4,5) is formed on top and bottom ends of the steel bar(3). The middle supporting body(10) is fixed on the bolt unit formed on the bottom end of the steel bar(30) to be rotatably connected.
