AI Technical Summary

Technical Problem

The top corner reinforcement plates on the top of the container are prone to water accumulation, which can lead to corrosion at the end cap connection and affect the service life of the container.

Method used

An inclined guide slope and drainage channel are designed between the top corner reinforcement plate and the top plate to form a drainage channel. The guide slope and the top plate form a water channel to guide the accumulated water out of the side of the container and prevent water residue.

Benefits of technology

While meeting the strength requirements of the container, it effectively drains accumulated water, prevents rust, and extends the service life of the container.

Claims

1. A container top drainage structure, characterized in that, Includes end caps, corner brackets, corner reinforcement plates, and top plates; The end lintel includes an end beam and an end lintel plate. The end lintel plate extends inward from the top of the end beam, and the top plate overlaps the upper surface of the end lintel plate. The corner piece is fixed to the end of the end beam. The corner reinforcement plate is welded to the upper surface of the end lintel and welded to the inner side wall and inner end wall of the corner piece. The corner reinforcement plate includes a first side facing the top plate, a second side facing the middle of the end lintel in the length direction, and a guide slope connecting the first side and the second side. A drainage groove is formed between the first side and the edge of the top plate. The guide slope gradually slopes away from the top plate from the outside to the inside in the length direction of the end lintel to form a water guide groove with a width that gradually decreases from the inside to the outside between the guide slope and the edge of the top plate. The water guide groove and the drainage groove are connected and together form a drainage channel.

2. The roof drainage structure of a container according to claim 1, wherein The end cap plate includes a sealing plate covering the top of the end crossbeam, a water baffle formed by bending the inner side of the sealing plate downward, and an extension plate formed by bending the bottom edge of the water baffle inward. The edge of the top plate overlaps the upper surface of the extension plate, and at least a portion of the first side, the guide oblique side, and the second side of the top corner reinforcing plate are located on the extension plate.

3. The roof drainage structure of a container according to claim 2, wherein The end beam includes an outer side wall, an inner side wall, and a bottom wall connecting the bottom of the outer side wall and the inner side wall. The top of the outer side wall is welded and fixed to the sealing plate, and the top of the inner side wall is welded and fixed to the extension plate.

4. The roof drainage structure of a container according to claim 3, wherein The top corner reinforcing plate includes a first section that covers the upper surface of the sealing plate and is welded to the sealing plate, a second section that covers the water baffle and is welded to the water baffle, and a third section that covers the extension plate and is welded to the extension plate.

5. The roof drainage structure of a container according to claim 2, wherein The outer edge of the sealing plate protrudes from the outer wall of the end beam to form a baffle. A downward bend is provided on the baffle so that the part of the baffle located outside the bend forms a downwardly inclined drainage plate.

6. The roof drainage structure of a container according to claim 1, wherein The thickness of the corner reinforcement plate is D1, and the thickness of the top plate is D2, with D1 / D2 being 1.5~2.

2.

7. The roof drainage structure of a container according to claim 1, wherein The width of the drainage channel is 8.3~11.6mm, and the maximum width of the water guide channel is 2~4 times the width of the drainage channel.

8. A container characterised in that, Includes the container top drainage structure as described in any one of claims 1-7.
