Detailed Description
In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the invention.
Fig. 1 is a schematic structural diagram of a container corner fitting 10 according to embodiment 1 of the present invention. As shown in fig. 1, the container corner fitting 10 may comprise: a top plate 11, a bottom plate 12, and side walls 13. The side wall 13 may be disposed between the top plate 11 and the bottom plate 12. The side walls 13 may be connected to the top plate 11 and the bottom plate 12 by welding. The side wall 13 also comprises at least two parts which are welded together. Specifically, grooves convenient for welding can be machined on each part according to the technological conditions. Therefore, the welding mode (laser welding, machine welding and other technologies) is adopted to avoid the defects of common air holes, sand inclusion, sand holes, insufficient pouring and the like of the casting type corner fitting, and the service life and the safety of the corner fitting are improved. Meanwhile, a large amount of dust and pollution generated by the traditional casting mode are avoided, and the health of operators is facilitated.
Correspondingly, the bottom plate 12 and the side walls 13 may be provided with through holes 14. Since the strength of the sidewall 13 is reduced when the sidewall 13 is formed with the through hole 14, a reinforcing plate 16 may be provided on the inner sidewall of the sidewall 13. The reinforcing plate 16 is also provided with through holes 14 which are adapted to be in communication with the through holes 14 in the side walls 13. The reinforcing plate 16 can be welded or integrally formed on the inner side wall of the side wall 13, so that the side wall 13 can have higher strength without thicker thickness, and further the overall weight of the container corner fitting 10 is reduced, so that the container corner fitting is 10% -40% lighter than a traditional cast corner fitting. For example, the top plate 11 and the side walls 13 may be 3-11mm thick. The thickness of the bottom plate 12 is 12-28.5mm, and the bottom plate 12 can also be provided with a through hole 14. The thickness of the side wall 13 (with the through hole 14) may be 3-11mm, and the thickness of the reinforcing plate 16 may be 3-10 mm.
Further, in embodiment 1, the reinforcing plate 16 is provided for stable fixation. The side of the top plate 11 corresponding to the reinforcement plate 16 may be provided with notches 15. The shape of the notch 15 is matched with the shape of the reinforcing plate 16, so that the end part of the reinforcing plate 16 can be clamped in the notch 15, and the reinforcing plate 16 can be stably arranged.
Fig. 2 is a schematic structural diagram of a container corner fitting 10 provided in embodiment 2, which is different from embodiment 1 in that no notch 15 is provided on the top plate 11 in embodiment 2. The top of the reinforcing plate 16 is flush with or lower than the top of the side wall 13. The reinforcing plate 16 may be provided on the side wall 13 by welding or integrally formed with the side wall 13.
Fig. 3 is a schematic structural diagram of a container corner fitting 10 provided in embodiment 3, which is different from embodiment 1 in that a plurality of notches 15 are formed on the side edge of the bottom plate 12 in embodiment 3, so as to form a step portion, and the lower end of the side wall 13 can be disposed on and fit with the step portion, so as to be welded with the bottom plate 12 more stably.
Fig. 4 is a schematic structural diagram of a container corner fitting 10 provided in embodiment 4, which is different from embodiment 1 in that a side wall 13 may be formed by two L-shaped metal members and a metal plate 132 respectively connected to two inner side walls of the L-shaped metal members. For example, referring to fig. 4, the L-shaped metal member may include a bent member 131 having a narrow side wall and an L-shaped metal member disposed opposite to the bent member. More specifically, the structure of the L-shaped metal piece includes a first plate extending in the length direction of the container corner fitting and a second plate extending in the width direction of the container. The thickness of the metal plate 132 is larger than the thickness of the L-shaped metal member and the bending member 131 having a narrow width. The metal plate 132 may be formed with a through hole 14. Since the metal plate 132 forming the side wall 13 is thick, and may be 5 to 20.5mm thick, the reinforcing plate 16 may not be provided. The side edges of the bottom plate 12 and the top plate 11 are provided with notches 15 adapted to the structure. Specifically, the thickness of the top plate 11, the side wall 13 and the minor side wall may be 3-11mm, and the thickness of the bottom plate 12 may be 12-28.5 mm.
Fig. 5 and 6 are schematic structural views of the container corner fitting 10 provided in embodiment 5, which is different from embodiment 1 in that the side wall 13 is formed by combining two L-shaped metal pieces, wherein one L-shaped metal piece can be formed by two thicker metal plates 132. The metal plate 132 is thick, and the reinforcing plate 16 may not be provided. Wherein, two metal plates 132 can be directly welded or connected by a connecting piece to form two side faces of the corner piece. Specifically, the thickness of the top plate 11 and the side wall 13 may be 3-11 mm. The thickness of the metal plate 132 may be 5-20.5 mm. The base plate 12 may be 12-28.5mm thick.
In the above described embodiments, the strength of the container corner fittings 10 is to be ensured. The container corner fitting 10 may be made of a material having a yield strength of >275MPa, and may be made of high strength steel or microalloyed steel, or a combination of several different yield strength steels (e.g., SPA-H or high strength steel combinations).
The present invention has been illustrated by the above embodiments, but it should be understood that the above embodiments are for illustrative and descriptive purposes only and are not intended to limit the invention to the scope of the described embodiments. Furthermore, it will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that many variations and modifications may be made in accordance with the teachings of the present invention, which variations and modifications are within the scope of the present invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
