Abstract

Disclosed is a base structure of the container, comprising a base frame and a board laid on the base frame, wherein, the boards near the threshold of the door end adopt the steel board; other boards adopt the wood board. The specification of the steel board and the wood board corresponds to the size of the relevant part of the base frame. The base structure in the utility model can replace the wood board at the two sides of the door, the front end or the bottom side beam with the steel board according to the actual operation condition, which can solve the problem that the board at door end of the existed container is easy to be damaged and much specification of the board.

Description

Container bottom structure

Technical field

The utility model relates to a kind of tun that is used for object or storing material or transportation, is specifically related to a kind of container bottom structure.

Background technology

Freight container is as a kind of international standard transportation means of multimetering transport, and it can ranked and stacked pile, thereby reduces transportation and storage cost, improves transportation and stores efficient, therefore is used widely in the whole world.Existing general-duty freight container generally is made up of a pair of side wall, door end, front end, top board and bottom construction.Wherein, container bottom structure by underframe and above the underframe wood covering of bedding form, and existing underframe is the rigid frame posture structure of mainly being made up of bottom cross beam and bottom side beams, the carrying structure of the interior goods of case is formed on underframe and floor jointly.

The bottom construction of existing general purpose container as shown in Figure 1, 2, wherein,

The birds-eye view of Fig. 1 for seeing from top to bottom by the existing cooresponding putting position of 20 forty equivalent unit 40 bottom constructions, as shown in FIG., 20 forty equivalent unit 40 bottom constructions comprise: the bottom side beams 4 of pair of parallel and be fixed in many foundation crossbeam 3 between two bottom side beams, promptly a threshold 1, the right-hand member that is fixed in two foundation curb girders 4 of door end are the underbeam 5 of front end and are fixed on wood covering 2 on the bottom cross beam 3 for the left end that is fixed in two foundation curb girders 4.

Fig. 2 birds-eye view that the cooresponding putting position of bottom construction is seen from top to bottom when normally using by existing 40 forty equivalent unit 40s, as shown in FIG., 40 forty equivalent unit 40 bottom constructions comprise: the bottom side beams 4 of pair of parallel and evenly be fixed in many foundation crossbeam 3 between two bottom side beams; The left end that is fixed in two foundation curb girders 4 is that the threshold 1 of door end, the right-hand member that is fixed in two foundation curb girders 4 are the underbeam 5 of front end; The Undercarriage structure right part also is provided with goose neck tunnel girder 6, short bottom cross beam 8 and formed goose neck tunnel 7 thereof; Wood covering 2 is fixed on the bottom cross beam 3 or lacks on the bottom cross beam 8.

As Fig. 1, shown in Figure 2, according to present design, the required wood covering specification of 20 forty equivalent unit 40s is 2 kinds: 2A and 2B, and the general specification that adopts of 2A is 1160mm * 1010mm, 2B is 1160mm * 2400mm; 40 forty equivalent unit 40s then need 3 kinds of specifications: i.e. 2B, 2C and 2D, and the general specification that adopts of 2C is 1160mm * 1388mm, 2D is 636mm * 1626mm; And all smaller near the wood covering 2A or the 2C at door end place, the bottom cross beam of support floor is few, also damages than being easier to, and also bad plate must be taken out during maintenance, changes new plate into, complex procedures, cost height.

Sum up it, all there are the problem of following two aspects in existing 20 feet, the bottom construction of 40 forty equivalent unit 40s:

One, owing to fork truck when container loading and unloaded of cargo frequently passes in and out, the frequency of utilization of chassis of container is to be reduced gradually by door end forward end with being subjected to impact load, caused the container door end plank to damage easily, particularly, then almost seldom damage near the floor of front end underbeam near first floor of door end threshold;

Two, on the other hand, because 20 feet, but 40 feet standard container is subjected to the qualification of the length dimension, 40 ' goose neck tunnel length dimension, wood covering finish size of ISO regulation etc., their wood covering is arranged all can use the little wood covering of different size specification, and the increase of wood covering dimensions brings great inconvenience for buying, the production of freight container and the maintenance of wood covering of wood covering.

Summary of the invention

The utility model is intended to overcome the deficiencies in the prior art, and a kind of container bottom structure is provided, and this structure can be damaged and the more problem of wood covering dimensions to solve existing container door end plank easily according to the needs that are fit to actual condition.

For achieving the above object, the utility model adopts following technical scheme:

A kind of container bottom structure, comprise underframe and be layed in floor on the underframe, described underframe comprise pair of parallel bottom side beams, be fixed in many foundation crossbeam between the bottom side beams, be fixed in the door end threshold of an end of two foundation curb girders and the front end underbeam that is fixed in the two foundation curb girder other ends; Steel floor is adopted on floor near described door end threshold part, and wood covering is adopted on the remainder floor, and the specification of described steel floor and wood covering is corresponding with described underframe corresponding site size.

Described container bottom structure wherein, all adopts steel floor near the floor of described door end threshold part and near the floor of described front end underbeam part, and wood covering is adopted on the remainder floor.

Described container bottom structure wherein, all adopts steel floor near the floor of described door end threshold part and near the floor at described two bottom side beams two ends, and wood covering is adopted on the remainder floor.

Described container bottom structure, wherein, described steel floor and wood covering respectively with the bottom cross beam Joint of described underframe relevant position.

The utility model has following beneficial effect:

1, the utility model is simple in structure, reasonable idea.It efficiently solves original container door end floor and often is damaged, changes floor difficulty, cost problem of higher with design simply.And adopt bottom construction of the present utility model, the intensity assurance that is easy to get in floor when being damaged, is safeguarded also comparatively simple;

2, on the other hand, bottom construction of the present utility model has reduced the specification on 20 feet and the 40 feet floors of using, and has made things convenient for buying, production and maintenance.

3, the utility model has not only overcome the processing difficulties that whole steel floor brought, and has also kept the advantage that wood covering is easy to restraint of loads, has reduced the use amount of wood covering simultaneously, has more the value of environmental protection.
