Layered horizontal tee joint

The invention aims at providing a layered horizontal tee joint. Layering steps are added in the horizontal tee joint and used for layered arrangement of cables in a bridge frame so as to achieve obvious distinguishing of the cable in the bridge frame, later repair and maintenance are facilitated, and the cables needing construction can be intuitively and quickly found. The layered horizontal tee joint comprises a tee joint body, triangular side plates, a rectangular base plate, base plate steps and side plate steps and is characterized in that two parallel triangular side plates are perpendicularly connected with the rectangular base plate to form the tee joint body, the base plate steps are perpendicularly connected to the rectangular base plate, and side plate steps are arranged between the two parallel triangular side plates. The layered horizontal tee joint has the advantages that the problem of converge and diffusion effects of the whole bridge frame in the horizontal direction is solved, multi-branch-path support is provided for the whole bridge frame, the internal anti-corrosion effect is improved through plastic spraying on the inner wall of the tee joint body, and the service life of the cables is prolonged.
