Abstract

The utility model discloses a bottom structure of container which comprises two lateral beams (1) and a plurality of transverse beams (2) and is characterized in that at least one longitudinal beam (3) keeping cross with the transverse beam is arranged between two lateral beams; a floor, made of a variety of materials including steel, wood, plastic and composite material, is covered on the a rigid frame formed by the transverse beam or the longitudinal beam. The utility model adds the longitudinal beam at a conventional chassis frame structure of the current container to strengthen the chassis frame and raise a load-bearing capacity of the floor so that the bottom structure consisting of the chassis frame and the floor can meet a demand of the container for the load-bearing capacity. Because the transverse beam and the longitudinal beam can stagger up and down, thereby a well processing performance can be achieved to meet a production requirement for a production line of container.

Description

Container bottom structure

Technical field

The utility model relates to freight container, especially a kind of bottom construction of freight container.

Background technology

Freight container development has in decades made the containerzation transportation be able to widespread use in the whole world.In the loading and unloading of goods and transportation, the main supporting region of freight container is the bottom construction that Undercarriage structure and the floor by freight container constitutes jointly.At present, the habitual Undercarriage structure of industry mainly is made up of two bottom side beams and Duo Gen crossbeams longitudinally, as shown in Figure 1, 2.The floor then is a hylaea hardwood Apitong wood covering.

Because the whole world particularly to the pay attention to day by day of hylaea, makes the raw material supply of existing container floor be subjected to great restriction to environmental protection, and container industry is caused harmful effect.In order to reduce or to break away from this restriction, people have studied or have attempted using the material of other resource abundances.

But the intensity on the floor made from the material of other resource abundances generally is lower than Apitong hardwood flooring intensity.Therefore, existing Undercarriage structure and the container bottom structure that constitutes than the low-intensity floor can not satisfy freight container to demands for bearing capacity.

Improve for the structure to chassis of container, the place, diagonal angle of the sash that continuous longeron, discontinuous longeron have occurred, constitutes at longeron and bottom cross beam is provided with bevelled and strengthens schemes such as support beam.The shortcoming that these schemes are outstanding is exactly that manufacturability is poor, is not suitable for the welding process requirement of freight container flow production line.

Summary of the invention

The utility model is will solve existing container bottom structure intensity can not satisfy technical matters to demands for bearing capacity or manufacturability difference, a kind of improved container bottom structure is provided, to improve the intensity of underframe, the load-carrying capacity on floor is improved, thereby the floor that can use various materials such as timber or plastics or steel or composite material etc. to make is to reduce or to break away from the restriction of Apitong raw material supply anxiety to container industry.Simultaneously, its fabrication properties should be got well, to meet the production requirement of container logistics waterline.

For addressing the above problem, the technical scheme that the utility model proposes is:

A kind of container bottom structure comprises two curb girders, many crossbeams, wherein, is provided with a longeron that interlocks with described crossbeam between described two curb girders at least, covers the different shape floor on the rigid frame that is made of described crossbeam and longeron.

Described many crossbeams can be located at the top of described longeron, also can be located at the below of described longeron.The floor of being made by various materials such as steel, timber, plastics or composite material etc. then covers on the rigid frame that crossbeam or longeron constitute.

The utility model adopts the structure that longeron is set between two curb girders, make the intensity of underframe increase on the one hand, making the floor test medium and small vehicle-mounted lotus on the other hand disperses, become many crossbeams and longeron carries jointly by single crossbeam, improved the load-carrying capacity on floor, the floor that can use various materials such as timber or steel or plastics or composite material etc. to make, thus can reduce or break away from of the restriction of Apitong raw material supply anxiety to container industry; Because longeron and crossbeam can be staggered up and down each other, so have process industrial art performance preferably, meet the production requirement of container logistics waterline.

The specific embodiment

A kind of container bottom structure comprises two curb girders 1, many crossbeams 2, and the quantity of crossbeam can be determined according to related standards, is provided with at least one longeron 3 that interlocks with described crossbeam between described two curb girders, and the radical of longeron can be selected according to different situations; Cover the different shape floor on the rigid frame that is made of described crossbeam and longeron, the cross-sectional plane of described crossbeam and described longeron can be multiple shapes such as L type, I type, T type, ∩ type, C type, frame type.

The specific embodiment 1: as shown in Figure 3, Figure 4, described many crossbeams are located at the top of described longeron, and the cross sectional shape of longitudinal and cross beam is the C type, and promptly the cross section opening of longitudinal and cross beam is towards a side, as shown in Figure 5.The floor then is layered on the rigid frame that crossbeam constituted that cross sectional shape is the C type.

The specific embodiment 2: as shown in Figure 3, Figure 4, a kind of container bottom structure, described many crossbeams are located at the top of described longeron, the cross sectional shape of longitudinal and cross beam then is the ∩ type, promptly the cross section opening of longitudinal and cross beam down, as shown in Figure 6.The floor then is layered on the rigid frame that crossbeam constituted that cross sectional shape is the ∩ type.

The specific embodiment 3: as Fig. 7, shown in Figure 8, described many crossbeams are located at the below of described longeron, and the cross sectional shape of longitudinal and cross beam is the ∩ type, and promptly the cross section opening of longitudinal and cross beam down.The floor then is layered on the rigid frame that longeron constituted that cross sectional shape is the ∩ type.

Because the utility model has been set up longitudinal beam in existing chassis of container structure, make that the intensity of described underframe is strengthened, the load-carrying capacity on floor improves, thereby after spreading the floor 5 of making at the upper surface of underframe by various materials such as steel, timber, plastics or composite material etc., its bottom construction can satisfy freight container to demands for bearing capacity, thereby can reduce or break away from the restriction of Apitong raw material supply anxiety to container industry; Because longeron and crossbeam can be staggered up and down each other, so have process industrial art performance preferably, meet the production requirement of container logistics waterline.
