Problems solved by technology

[0005] At this stage, due to the frequent international trade, the volume of container transportation has increased sharply. People use some methods to increase the transportation efficiency of containers. The most intuitive way to increase the transportation efficiency of containers is to increase the space inside the container. To load more goods, some ultra-wide and ultra-long containers used in Europe and the United States have a larger internal space than ordinary containers and a relatively large amount of cargo. However, their external dimensions do not meet the requirements of the ISO standard and cannot be used for container ships. intermodal

Embodiment 1

[0034] Such as Figure 4 , 5 The shown container underframe 3 includes bottom side beams 300 on both sides, thresholds 301 and front end lower beams 302 located at both ends of the underframe, and a plurality of side beams parallel to and arranged between the thresholds 301 and front end lower beams 302 Bottom crossbeam 303 has bottom corner fittings 361 welded at both ends of threshold 301 and front end lower beam 302; above-mentioned bottom side beam 300, bottom crossbeam 303, threshold 301 and front end lower beam 302 are welded into a frame body, The wooden floor 37 is laid on the frame body, and its middle part is supported on the top surface of the bottom beam 303 . The inner side of the threshold 301 is provided with a threshold bending section 3011 for carrying the wooden floor 37 downwards and its upper surface is flush with the top surface of the bottom beam 303. Correspondingly, in order to ensure the smoothness of the wooden floor 37 of the container, the front en...

Embodiment 2

[0040] In order to increase the height of the inner space of the container more effectively, reduce the height of the bottom frame of the container, such as Figure 8 , 9 As shown, a notch 3611 is provided on the bottom corner piece 361 at the matching part overlapping with the wooden floor 37, and the end corner of the wooden floor 37 can be placed in the notch 3611, and the depth of the notch 3611 is the same as that of the wooden floor 37. The same thickness, so that the upper surface of the wooden floor 37 is flush with the upper surface of the bottom corner piece 361. Here, the purpose of opening the recess 3611 on the bottom corner piece is to maintain the structural integrity of the wooden floor 37 . From the purpose of realizing the support of the bottom corner piece 361 to the wooden floor 37, it is also possible to adopt such as Figure 10 In the shown manner, that is, a support platform 3612 for supporting the wooden floor is provided at the periphery of the botto...

Abstract

The invention relates to a container underframe comprising a doorsill, a frontend underbeam, a plurality of bottom cross beams, a floor and ISO standard bottom corner fittings, wherein the doorsill and the frontend underbeam are respectively positioned at both ends of the underframe and are mutually parallel; the bottom cross beams are positioned between the doorsill and the frontend underbeam and are parallel to the doorsill and the frontend underbeam; the floor is laid on the top of the underframe; the ISO standard bottom corner fittings are positioned at the four end corner bottoms of the underframe and are connected to the ends of the doorsill and the frontend underbeam; the floor is overlapped on the doorsill, the frontend underbeam and the bottom cross beams; the upper planes of the contacting parts of the doorsill and the frontend underbeam with the floor are aligned with the upper planes of the bottom corner fittings; and the four end corners of the floor are overlapped on the upper planes of the four bottom corner fittings. By reducing the height of the doorsill, the frontend underbeam and the bottom cross beams, the upper planes of the doorsill, the frontend underbeam and the bottom cross beams can be aligned with the upper planes of the bottom corner fittings, and the four end corners of the floor are overlapped on the upper planes of the bottom corner fittings, so as to increase the interior height of a container.

Description

technical field [0001] The invention relates to parts of a large container, in particular to a container underframe structure. Background technique [0002] As the main tool of international combined transport, containers have been widely used since 1956 and have been used for more than 50 years. With the continuous strengthening of international trade, container transport has become the main means of international combined transport. [0003] At present, the overall configuration of general-purpose containers is hexahedral. In terms of specific structures, such as figure 1 As shown, it generally includes an underframe platform 10 at the bottom of the box, front walls 12 and box doors 13 at both ends of the underframe platform 10, side walls 11 on both sides of the box, and the top of the box. The top plate 14 of the side wall 11, the corner posts 15 vertically positioned at the four end corners of the chassis platform 10 at the connection between the side wall 11 and the f...
