The specific embodiment
In the following description, having provided a large amount of concrete details understands the utility model more thoroughly to provide.Yet, it will be apparent to one skilled in the art that the utility model embodiment can be implemented without one or more these details.In other example, for fear of obscuring with the utility model embodiment, for technical characterictics more well known in the art, be not described.
In order thoroughly to understand the utility model embodiment, will detailed structure be proposed in following description.Obviously, the execution of the utility model embodiment is not limited to the specific details that those skilled in the art has the knack of.Preferred embodiment of the present utility model is described in detail as follows, yet except these are described in detail, the utility model can also have other embodiments.
The utility model provides a kind of freight container.This freight container generally comprises a pair of side wall, door end, holds relative front end, top board and underframe with door.Simple in order to illustrate, the utility model only shows the underframe of freight container.Below in conjunction with Fig. 1 and Fig. 2, underframe 100 of the present utility model is elaborated.
As depicted in figs. 1 and 2, underframe 100 comprises bottom side beams 110, bottom cross beam 120 and floor 130.Wherein, bottom side beams 110 lays respectively at the two bottom sides of freight container, along the longitudinal extension of freight container.It should be noted in the discussion above that " longitudinally " described here refer to the length direction of freight container, " laterally " that hereinafter will mention refers to direction vertical with " longitudinally " in horizontal surface.Bottom cross beam 120 is between bottom side beams 110.Generally, bottom cross beam 120 between bottom side beams 110 perpendicular to bottom side beams 110 ground settings.The shape of the cross-sectional plane of bottom cross beam 120 can be one or more in C type, L-type and I shape.Certainly, the utility model limits the shape of the cross-sectional plane of bottom cross beam 120 without wish, and it can, according to actual conditions, adopt existing any suitable crossbeam 120.
Floor 130 be laid on bottom cross beam 120 above and along the longitudinal extension of freight container.According to design of the present utility model, floor 130 can comprise along one or more steel floor 131 of the horizontal alternative arrangement of freight container and many wood coverings 132, to reduce the use of timber.Wherein, every wood covering 132 all equates along horizontal size h1, to unify the dimensions of wood covering 132, facilitates finished wood floors 132.In addition, preferably, when the number of steel floor 131 is two or more, steel floor 131 also can equate along horizontal size h2, to unify processing and manufacturing steel floor 131.
Can determining according to actual conditions along horizontal size of wood covering 132.According in an embodiment of the present utility model, wood covering 132 along horizontal size, can be 636mm.The existing floor with goose neck tunnel is generally generally 636mm in the size of the wood covering of the both sides of goose neck tunnel.Therefore, according in an embodiment of the present utility model, wood covering 132 can be further that the dimensions of the wood covering of the dimensions of wood covering 132 and goose neck tunnel is unified along the horizontal 636mm that is of a size of, facilitate processing and fabricating.
According to international standard, freight container size is transversely generally 2438mm.Preferably, according in an embodiment of the present utility model, when wood covering 132 is along horizontal while being of a size of 636mm, the number of wood covering 132 can be three, and the number of steel floor 131 can be two.In this case, can make freight container being of the required size transversely by adjusting the bottom side beams 110 of underframe 100 and the size along horizontal of steel floor 131.
As example, according in an embodiment of the present utility model, can widen the width of bottom side beams 110, as depicted in figs. 1 and 2.The width of the bottom side beams 110 of existing freight container is generally 82mm, therefore bottom side beams 110 can be widened along horizontal size h3, makes it be greater than 82mm.Yet, bottom side beams 110 can not be too large along horizontal size.In general, the place, four bights of the underframe of freight container can arrange corner fittings 140, so that conveying container.Bottom side beams 110 along horizontal size should be less than corner fittings 140 along horizontal size h4.Standard corner fitting 140 is generally 162mm along horizontal size h4.Therefore, according in an embodiment of the present utility model, the size h3 along horizontal of bottom side beams 110 is greater than 82mm and is less than or equal to 162mm.
Correspondingly, steel floor 131 can be 100mm~170mm along horizontal size h2, to meet freight container along horizontal dimensional characteristic.
In addition, also can not adjust bottom side beams 110 along horizontal size, and only adjust steel floor 131 along horizontal size.As example, according in another embodiment of the present utility model, as shown in Figure 3 and Figure 4, the floor 230 of underframe 200 comprises three wood coverings 232 and two steel floors 231.Wood covering 232 is similarly 636mm along horizontal size h1.Bottom side beams 210 along horizontal size h5, do not do any adjustment, be still 82mm.And steel floor 231 is adjusted into 160mm~220mm along horizontal size h6, to meet freight container along horizontal dimensional characteristic.
Steel floor 131 can be flat board, also can have for cross-sectional plane the corrugated plating of bellows-shaped.As example, according in an embodiment of the present utility model, the cross-sectional plane of steel floor 131 can be omega type, as shown in Figure 2.Cross-sectional plane is that the steel floor 131 of omega type has upper horizontal part, is connected to two vertical portions of two ends of horizontal part and two lower horizontal parts that are connected with two vertical portions and extend laterally.Wherein vertical portion can be vertical with lower horizontal part with upper horizontal part, as shown in Figure 2, also can and upper horizontal part and lower horizontal part between be inclination angle.Cross-sectional plane is that the steel floor 131 of omega type has good tensile strength, thereby can improve tensile strength and the load-carrying capacity on floor 130.
In sum, according to the floor of freight container of the present utility model, be the floor that steel wood is arranged alternately, and wood covering have identical size, can facilitate the processing and fabricating of wood covering.
The utility model is illustrated by above-described embodiment, but should be understood that, above-described embodiment is the object for giving an example and illustrating just, but not is intended to the utility model to be limited in described scope of embodiments.In addition it will be understood by those skilled in the art that; the utility model is not limited to above-described embodiment; according to instruction of the present utility model, can also make more kinds of variants and modifications, these variants and modifications all drop in the utility model scope required for protection.
