     TECHNICAL FIELD 
     The utility model relates to components and parts of a container, and in particular, to a support member of a container. 
     BACKGROUND ART 
     In the 1960s, the container has developed into a multimodal transport and international universal means of transportation, and the container refers to a large loading vessel which has certain strength, stiffness and specifications specifically for use in turnover. When the container is used to transport goods, the goods may be loaded directly in a shipper&#39;s warehouse and then transported to a consignee&#39;s warehouse for unloading, and it is unnecessary to take out and reload the goods from the container when a vehicle or ship is changed midway. A simple container has a unified specification, and its structural design has an advantage both in the assembly speed per production unit and the production cost. An international commonly used container is enclosed by a bottom side beam, a bottom beam, a corner column, a corner fitting and a top side beam to form a frame, and sheet materials are mounted on surfaces where the frame is located to form the container body.  FIG.  1    partially shows a local structure of the existing container.  FIG.  2    shows a structure of a top side beam in a container in a sectional state. As shown in  FIG.  1    and  FIG.  2   , the top side beam  90  is one of the important components of the container  9 , and a 60*60 mm square-tube top side beam structure is generally adopted in the prior art, wherein a first surface  91  of the square-tube top side beam  90  is connected to a top plate  93 , and a second surface  92  of the square-tube top side beam is connected to a side plate  94 ; in this way, the top plate  93  and the side plate  94  are connected together through the square-tube top side beam  90 . 
     However, during actual use, the square-tube top side beam structure has some disadvantages, for example, during actual transportation of a container loaded through a semi-trailer, as the top side beam of the container has a relatively small distance in a height direction, the top side beam can only play a role of supporting the top plate of the container; once the container is subject to a greater external impact, the top side beam can hardly play a role of protection, and the side plate near the top side beam is easily punctured by other containers; in some more serious situations, the goods in the container may also be damaged because the container is punctured, so that the container cannot be used normally, thereby reducing the overall use efficiency of the container. 
     In view of this, transportation enterprises expect that the protection function of the top side beam is improved through improvement on the top side beam so as to enhance the overall security of the container, which thus ensures transportation security of the goods in the container. 
     SUMMARY OF THE UTILITY MODEL 
     An object of the utility model is to provide a top side beam of a container. The top side beam of the container has a protection capability, can effectively reduce adverse impacts of an external force on the top side beam and a side plate near the top side beam to prevent the container from being damaged by an external impact and then improve the overall strength of the container, thereby avoiding that the container body is punctured and ensuring integrity and security of goods in the container. In addition, the top side beam of the container according to the utility model has a simple structure, is easy to manufacture, and facilitates convenient modification of the container. 
     In order to achieve the above object, the utility model provides a top side beam of a container, which has a web plate that extends vertically along a height direction of the container, to increase a vertical height of the top side beam to above 100 mm. 
     Different from the tube-type top side beam in the prior art, the top side beam of the utility model is provided with a web plate that extends vertically along the height direction of the container, and thus the top side beam has a greater size in the height direction of the container. That is to say, the side plate part originally disposed adjacent to the top side beam in the side plate of the container is replaced with the web plate of the top side beam that extends vertically in the height direction of the container; in this way, once subject to an enormous external force, the top side beam can play a better protection role, so as to avoid that the side plate of the container is punctured. 
     In the above technical solution, if the vertical height of the top side beam cannot reach more than 100 mm, the top side beam can play a small protection role of resisting the external force; to this end, it is necessary to maintain the vertical height of the top side beam more than 100 mm, so as to provide favorable protection measures for the top plate and/or the side plate of the container and the whole container. 
     Based on the technical solution of the utility model, there are no strict restrictions on the shape of the web plate and its own structure, which may be set according to actual production and manufacturing demands, as long as the top side beam having the web plate can adapt to the structure of the container. 
     Further, in the top side beam of the container according to the utility model, the vertical height of the top side beam is increased to 150-400 mm. 
     In terms of the top side beam of the container according to the utility model, if the vertical height of the top side beam is too small, it is impossible to provide favorable protection for the container; if the vertical height of the top side beam is too great, on one hand, it will affect structural settings of the side plate and the top plate connected to the top side beam, and on the other hand, it will increase material investment of the top side beam and increase the production and manufacturing difficulty of the top side beam. To this end, the vertical height of the top side beam is set between 150-400 mm, which can ensure the protection function of the top side beam without appreciably affecting the structure or weight of the container and increasing the production and manufacturing cost of the top side beam. A skilled artisan in possession of the invention will appreciate that a further increase in vertical height will further increase the weight and cost of the beam and the container, and that these considerations should be balanced against the desire for a top side beam in accord with the invention that provides acceptable impact protection. 
     Further, the top side beam of the container according to the utility model includes a top side beam body and the web plate fixedly connected to a side of the top side beam body, the web plate being used to shelter or protect an upper edge of the side plate of the container. 
     Based on the above technical solution, in one implementation, the top side beam body and the web plate fixedly connected therewith are integrally formed, that is to say, there is no connecting gap between the top side beam body and the web plate; in another implementation, the top side beam body and the web plate fixedly connected therewith are not integrally formed, that is to say, a fixed connection between the top side beam body and the web plate may be achieved through an existing connection manner, for example, welding or the top side beam body and the web plate may be connected through a bolt assembly. 
     Further, the top side beam of the container according to the utility model includes: an upper wing plate, a lower wing plate and a vertical plate which is connected between the upper wing plate and the lower wing plate as the web plate. 
     Based on the above technical solution, the upper wing plate is connected to a top plate of the container, and the lower wing plate is connected to a side plate of the container. Compared with the top plate or the side plate of the container, the vertical plate connected between the upper wing plate and the lower wing plate has a higher strength and a higher capability of resisting an external impact force. Furthermore, a vertical section of the top side beam is C-shaped or Z-shaped or S-shaped or I-shaped or rectangular. The wing plate can be formed of one or more metals or other force-resistant materials, and can be, for example, a steel plate. 
     Based on the technical solution of the utility model, the vertical section of the top side beam may be diverse. Herein, the top side beam of which the vertical section is C-shaped includes “C”-shaped (that is, normal C-shaped) top side beam opening towards right and also includes “ ”-shaped (that is, inverted C-shaped) top side beam opening towards left, and the normal C-shaped top side beam and the inverted C-shaped top side beam have mirror symmetry therebetween. Similarly, the Z-shaped top side beam also includes “Z”-shaped (that is, normal Z shape) top side beam and “ ”-shaped (that is, inverted Z shape) top side beam; and the S-shaped top side beam also includes “S”-shaped (that is, normal S-shaped) top side beam and “ ”-shaped (that is, inverted S-shape) top side beam. 
     It should be noted that, although the vertical plate or a partial structure of the vertical plate in the Z-shaped top side beam or the S-shaped top side beam is disposed obliquely, it also belongs to the “vertical plate” defined in the technical solution of the utility model. 
     In some implementations, when the vertical section of the top side beam is C-shaped or Z-shaped or S-shaped or I-shaped, the upper wing plate and/or the lower wing plate have/has a flange extending downwards or provided with a rolled (not sharp) edge that can further avoid impact damage to the container or its cargo. 
     Based on the above technical solution, the top side beam of which the vertical section is C-shaped includes a top side beam in a normal C shape and a top side beam in an inverted C shape; the top side beam of which the vertical section is Z-shaped includes a top side beam in a normal Z shape and a top side beam in an inverted Z shape; and the top side beam of which the vertical section is S-shaped includes a top side beam in a normal S shape and a top side beam in an inverted S shape. 
     A flange extending downwards is disposed on the upper wing plate or the lower wing plate or on both of them, with the purpose of further improving the strength of the upper wing plate and/or the lower wing plate, and at the same time, reducing adverse deformation that may occur when the top side beam is welded with the top plate of the container and/or the side plate of the container and reducing the welding difficulty. 
     Compared with a flange extending upwards, the upper wing plate and/or the lower wing plate being provided with a flange extending downwards may not affect drainage of the container while enhancing the strength of the upper and lower wing plates, which favorably avoids ponding of the container at the top side beam. 
     In some other implementations, when the vertical section of the top side beam is C-shaped or Z-shaped or S-shaped or I-shaped, a support plate is further provided between a free end of the upper wing plate and/or the lower wing plate and the vertical plate. 
     Based on the above technical solution, the top side beam of which the vertical section is C-shaped includes a top side beam in a normal C shape and a top side beam in an inverted C shape; the top side beam of which the vertical section is Z-shaped includes a top side beam in a normal Z shape and a top side beam in an inverted Z shape; and the top side beam of which the vertical section is S-shaped includes a top side beam in a normal S shape and a top side beam in an inverted S shape. 
     Herein, the free end of the upper wing plate refers to the end on the upper wing plate which is away from the vertical plate, and the free end of the lower wing plate refers to the end on the lower wing plate which is away from the vertical plate. 
     A support plate being disposed between the free end of the upper wing plate and the vertical plate is to improve the strength of the upper wing plate, reduce adverse deformation that may occur when the top side beam is welded with the top plate of the container and reduce the welding difficulty. Similarly, a support plate being disposed between the free end of the lower wing plate and the vertical plate is to improve the strength of the lower wing plate, reduce adverse deformation that may occur when the top side beam is welded with the side plate of the container and reduce the welding difficulty. 
     Based on the above implementation, under one circumstance, a support plate independent of the free end of the upper wing plate and/or the lower wing plate and the vertical plate is connected between them, that is to say, the support plate may achieve a fixed connection between it and the free end of the upper wing plate and/or the lower wing plate as well as the vertical plate through an existing connection manner (for example, welding) respectively. Under another circumstance, the free end of the upper wing plate and/or the lower wing plate and the support plate are integrally formed, that is to say, the support plate is formed by directly extending the free end of the upper wing plate and/or the lower wing plate to the vertical plate. 
     Furthermore, in the top side beam of the container according to the utility model, a stiffener protruding beyond a plate surface of the web plate is provided on the web plate. 
     As the probability that the web plate directly comes into contact with the external impact is the highest and the web plate is the easiest to deform and recess, disposing a stiffener protruding beyond a plate surface thereof on the web plate is for the purpose of improving the strength of the web plate and enhancing the resistance of the web plate to the external force. 
     Herein, the shape and structure of the stiffener may be diversified, for example, it may be a stiffener of which the vertical section is rectangular, may be a stiffener of which the vertical section is trapezoidal, and may also be a stiffener of which the vertical section is semicircular, or a stiffener of which the vertical section is triangular. 
     Similarly, the number of the stiffener is not strictly specified, which may be one or more. 
     Furthermore, the top side beam includes at least a first part and a second part vertically superposed in an order from top to bottom, wherein shapes of vertical sections of the first part and the second part are selected from at least one of C shape, Z shape, S shape, I shape and rectangular shape; and the vertical plate includes at least a vertical plate of the first part and a vertical plate of the second part. 
     Based on the above technical solution, the top side beam of which the vertical section is C-shaped includes a top side beam in a normal C shape and a top side beam in an inverted C shape; the top side beam of which the vertical section is Z-shaped includes a top side beam in a normal Z shape and a top side beam in an inverted Z shape; and the top side beam of which the vertical section is S-shaped includes a top side beam in a normal S shape and a top side beam in an inverted S shape. 
     In the above technical solution, the top side beam may also be obtained through pairwise superposition, and thus the vertical plate of the top side beam is made up of vertical plates superposed and combined, to further improve the protection capability of the top side beam and enhance the overall strength of the container. 
     In addition, the vertical height of the top side beam may be increased through superposition on the basis of the original top side beam, avoiding abandonment of the existing top side beam. 
     In addition, full use of different types of top side beams is also achieved through superposition, which has good flexibility and strong convenience. 
     Certainly, the number of the superposition part in the top side beam is not strictly restricted, which may be set according to actual production and manufacturing demands, as long as the top side beam obtained through superposition may not affect the structure of the container, for example, the top side beam may include a first part, a second part and a third part vertically superposed in an order from top to bottom. 
     Furthermore, an upper wing plate formed on the first part of which the vertical section is C-shaped or Z-shaped or S-shaped or I-shaped and/or a lower wing plate formed on the second part of which the vertical section is C-shaped or Z-shaped or S-shaped or I-shaped have/has a flange extending downwards. 
     Based on the above technical solution, the top side beam of which the vertical section is C-shaped includes a top side beam in a normal C shape and a top side beam in an inverted C shape; the top side beam of which the vertical section is Z-shaped includes a top side beam in a normal Z shape and a top side beam in an inverted Z shape; and the top side beam of which the vertical section is S-shaped includes a top side beam in a normal S shape and a top side beam in an inverted S shape. 
     When the first part and/or the second part adopt/adopts a structure of which the vertical section is C-shaped or Z-shaped or S-shaped or I-shaped, an upper wing plate of the first part and/or a lower wing plate of the second part are/is provided with a flange extending downwards to further improve the strength of the first part and/or the second part, which thus improves the strength of the top side beam, reduces adverse deformation that may occur when the top side beam is welded with the top plate of the container and/or the side plate of the container and reduces the welding difficulty. 
     Compared with a flange extending upwards, the upper wing plate of the first part and/or the lower wing plate of the second part being provided with a flange extending downwards may not affect drainage of the container while enhancing the strength of the upper and lower wing plates, which favorably avoids ponding of the container at the top side beam. 
     Furthermore, the vertical plate of the first part of which the vertical section is C-shaped or Z-shaped or S-shaped or I-shaped and/or the vertical plate of the second part of which the vertical section is C-shaped or Z-shaped or S-shaped or I-shaped have/has a stiffener protruding beyond its own plate surface. 
     Based on the above technical solution, the top side beam of which the vertical section is C-shaped includes a top side beam in a normal C shape and a top side beam in an inverted C shape; the top side beam of which the vertical section is Z-shaped includes a top side beam in a normal Z shape and a top side beam in an inverted Z shape; and the top side beam of which the vertical section is S-shaped includes a top side beam in a normal S shape and a top side beam in an inverted S shape. 
     It should be noted that the stiffener may adopt different types of structure or shape, for example, it may be a stiffener of which the vertical section is rectangular, may be a stiffener of which the vertical section is trapezoidal, and may also be a stiffener of which the vertical section is semicircular, or a stiffener of which the vertical section is triangular. 
     Evidently, the structure and/or the number of the stiffeners disposed on the vertical plate of the first part may be the same as or different from the structure and/or the number of the stiffeners disposed on the vertical plate of the second part. 
     Another object of the utility model is to provide a container, the container has higher strength, especially the top side beam of the container and the side plate connected to the top side beam have high strength, which is not easy to deform under the action of external impact, effectively avoids that the side plate of the container is punctured, favorably ensures the integrity of goods in the container, and reduces the loss ratio of the transported goods. 
     In order to achieve the above object, the utility model further proposes a container, which has any of the top side beams as mentioned hereinabove. 
     The top side beam according to the utility model can effectively resist external impact, which has a good protection function. 
     In addition, the top side beam according to the utility model can favorably reduce adverse impact of the external impact on the top side beam and the side plate connected to the top side beam to prevent the container from being damaged by an external force and then improve the overall strength of the container, thereby avoiding that the container body is punctured and ensuring integrity and security of goods in the container. 
     In addition, the top side beam of the container according to the utility model has a simple structure, is easy to manufacture, and facilitates convenient modification of the container. 
     At the same time, the top side beam of the container according to the utility model has a long service life, an economic production cost and an extensive application range.

The support plates  14  and  15  are triangular structures formed by directly extending the free end of the upper wing plate  11  and the free end of the lower wing plate  12  to the vertical plate  13  respectively, that is to say, the upper wing plate  11  and the support plate  14  are integrally formed, and at the same time, the lower wing plate  12  and the support plate  15  are also integrally formed. 
     As shown in  FIG.  4   , reference may be made to  FIG.  3    if necessary, the free end of the upper wing plate  11  refers to the end on the upper wing plate  11  which is away from the vertical plate  13 , and the free end of the lower wing plate  12  refers to the end on the lower wing plate  12  which is away from the vertical plate  13 . 
     Similarly, in the top side beams shown in the following drawings, the free end of the upper wing plate refers to the end on the upper wing plate which is away from the vertical plate, and the free end of the lower wing plate refers to the end on the lower wing plate which is away from the vertical plate.

The flanges  16  and  17  are formed by directly bending the upper wing plate  11  and the lower wing plate  12  downwards respectively, that is to say, the upper wing plate  11  and the flange  16  are integrally formed, and the lower wing plate  12  and the flange  17  are also integrally formed. 
     Compared with a flange extending upwards, the flange extending downwards may not affect drainage of the container while enhancing the strength of the upper and lower wing plates, which favorably avoids ponding of the container at the top side beam. 
     In another implementation, the vertical section of the top side beam may also be in an inverted S shape.

A stiffener  18  protruding beyond a plate surface of the web plate is provided on the web plate, and a vertical section of the stiffener  18  is trapezoidal, wherein the lower wing plate  12  has a flange  17  extending downwards, so as to improve the strength of the lower wing plate, reduce adverse deformation that may occur when the top side beam  1  is welded with the side plate  72  of the container and reduce the welding difficulty. The flange  17  is formed by directly bending the lower wing plate  12  downwards, that is to say, the lower wing plate  12  and the flange  17  are integrally formed. 
       FIG.  11    shows a structure of the top side beam of the container according to the utility model in a fifth implementation.  FIG.  12    shows a structure of the top side beam in a mounting state. 
     As shown in  FIG.  11    and  FIG.  12   , the structure of the top side beam in the implementation is similar to that of the top side beam in the fourth implementation, and their difference lies in that: the vertical section of the second part b in the top side beam is in an inverted C shape.

A stiffener  88  protruding beyond a plate surface of the web plate is provided on the web plate, and a vertical section of the stiffener  88  is trapezoidal. A support plate  84  is provided between a free end of the upper wing plate  81  and the vertical plate  83 , and a support plate  85  is also provided between a free end of the lower wing plate  82  and the vertical plate  83 .

The upper wing plate  81  is fixedly connected to a top plate  86  of the container, and the lower wing plate  82  is fixedly connected to a side plate  87  of the container. 
       FIG.  36    and  FIG.  37    show an embodiment of a container in accord with the invention wherein the top side beam has a web plate that extends vertically along the height direction of the container to increase the vertical height of the top side beam to above 100 mm, wherein the top side beam includes an upper wing plate  11 , a lower wing plate  12  and a vertical plate  13  which is connected between the upper wing plate  11  and the lower wing plate  12  forming the top side beam. The vertical plate  13  has longitudinal corrugations that run the full length of the vertical plate to add torsional stiffness and increase the impact resistance of the vertical plate. Moreover, the lower wing plate is rolled back upon itself such that no sharp edge protrudes toward the side plate of the container and risk of impact damage to the side plate or the goods in the container is avoided. 
     As some other main structures (for example, the bottom side beam, the bottom beam and the like) in the container and the underframe of the container of the utility model are not evidently different from the structure adopted in the prior art, they are not described in detail herein through other specification drawings. 
     It should be noted that the above description of the embodiments disclosed enables those skilled in the art to obviously make lots of similar changes and modifications to the embodiments, for example by substituting one disclosed aspect of the top side beam for another, or by adjusting the relative dimensions of various aspects of the top side beam. Such similar changes are all transformations that those skilled in the art can directly obtain from the content disclosed in the utility model or easily associate, and all belong to the protection scope of the utility model. Therefore, the utility model may not be limited by the embodiments.
