The invention provides a kind of freight container.This freight container can comprise a pair side wall, Men Duan, hold relative front end, top board and the underframe 100 as hereafter discussed in detail with door.As depicted in figs. 1 and 2, underframe 100 floor 130 that comprises a pair bottom side beams 110, multiple bottom cross beam 120 and be laid on bottom side beams 110 and bottom cross beam 120.Below in conjunction with Fig. 1-Fig. 3, the underframe 100 of freight container is described in detail.
As depicted in figs. 1 and 2, a pair bottom side beams 110 of underframe 100 is separately positioned on the both sides of the bottom of freight container and arranges along the longitudinal direction of freight container in parallel with each other.Multiple bottom cross beam 120 is connected between a pair bottom side beams 110, and along the horizontally set of freight container.It should be noted that, " longitudinal direction " mentioned herein refers to the length direction of freight container.Correspondingly, " transverse direction " refers to direction vertical with the length direction (i.e. " longitudinal direction ") of freight container in horizontal surface, i.e. the Width of freight container.Under normal circumstances, multiple bottom cross beam 120 is arranged in parallel to each other.The shape of the cross-sectional plane of bottom cross beam 120 can be one or more in C type, L-type, T-shaped and I shape etc. substantially.
In order to reduce the use of wood covering, floor 130 transverse direction that can comprise along freight container is alternately arranged and along the steel floor 131 of the longitudinal extension of freight container and wood covering 132.Wherein, in order to strengthen the intensity of steel floor 131, the cross-sectional plane of steel floor 131 can be omega type, as shown in Figure 2.Particularly, the cross-sectional plane of the steel floor 131 lower horizontal part 131C that can comprise horizontal part 131A, extend to both sides from the vertical portion 131B of two ends to downward-extension of upper horizontal part 131A and the lower end on even keel from vertical portion 131B.Wood covering 132 is overlapped on the lower horizontal part 131C of the steel floor 131 be adjacent.Wherein, wood covering 132 can between two adjacent steel floors 131, also can between a steel floor 131 and longeron 110.When wood covering 132 is between two adjacent steel floors 131, the both sides of wood covering 132 can be overlapped on the lower horizontal part 131C of the steel floor 131 being positioned at both sides respectively.And when wood covering 132 is between bottom side beams 110 and steel floor 131, the side of wood covering can be overlapped on the lower horizontal part 131C of steel floor 131, opposite side then can by overlapping or being fixed in bottom side beams 110 by the mode such as to be spirally connected.
Can be clear that from Fig. 2, because wood covering 132 is overlapped on the lower horizontal part 131C of steel floor 131, therefore in the lap-joint of wood covering 132 with the lower horizontal part 131C of steel floor 131, the gross thickness (the thickness sum of the thickness of wood covering 132 and the lower horizontal part 131C of steel floor 131) on floor 130 is thicker than the thickness in other regions of wood covering 132.In this case, when floor 130 is laid on common bottom cross beam, only the floor of lap-joint contacts with bottom cross beam, and the floor in other regions may be unsettled, causes the intensity of underframe to reduce.Therefore, according to a preferred embodiment of the present invention, as shown in Figures 2 and 3, bottom cross beam 120 on the load-bearing surface of load carrying floor 130, be provided with depressed part 121.When floor 130 is laid on multiple bottom cross beam 120, the lower horizontal part 131C of steel floor 131 is contained in depressed part 121.And other parts of wood covering 132 directly can contact with bottom cross beam 120, thus the intensity of underframe 100 can be improved.
The degree of depth of depressed part 121 can be determined according to actual conditions.Preferably, the degree of depth of depressed part 121 equals the thickness of the lower horizontal part 131C of steel floor 131.Wherein, it should be noted that, the degree of depth of depressed part 121 refers to the vertical distance of the upper surface of bottom cross beam 120 to the inside face of the bottom of depressed part 121.In this case, the lower horizontal part 131C of steel floor 131 just can be contained in depressed part 121 in a thickness direction.Thus the lower horizontal part 131C of steel floor 131 and other regions of wood covering 132 can directly contact with bottom cross beam 120 and be supported on bottom cross beam 120, improve the intensity of underframe 100 further.
Similarly, the width of depressed part 121 also can be determined according to actual conditions.Preferably, the width of depressed part 121 equals the maximum width of steel floor 131.Wherein, it should be noted that, " maximum width " mentioned here refers to the distance between the outside of two of steel floor 131 lower horizontal part 131C.In this case, the lower horizontal part 131C of steel floor 131 can just be contained in depressed part 121 in the direction of the width, avoids there is gap.
The depressed part 121 of bottom cross beam 120 can be made by techniques such as such as punching presses.For the ease of processing and fabricating, according to a preferred embodiment of the present invention, bottom cross beam 120 can have identical cross-sectional plane at diverse location place.Particularly, as shown in Figure 3, when bottom cross beam 120 on the load-bearing surface of load carrying floor 130, be provided with depressed part 121 time, correspondingly, the surface relative with the load-bearing surface of load carrying floor 130 of bottom cross beam 120 is also provided with depressed part 122, wherein the depression direction of depressed part 122 and the degree of depth are all identical with the direction of depressed part 121 and the degree of depth, so that processing and fabricating.
In order to strengthen the intensity of underframe 100, steel floor 131 and bottom cross beam 120 can be fixedly connected with by the mode such as such as welding.In addition, because wood covering 132 is overlapped on the lower horizontal part 131C of steel floor 131, in order to strengthen wood covering 132, connection between steel floor 131 and bottom cross beam, connecting element 140 can also be set further at wood covering 132 and the lap-joint of steel floor 131, bottom cross beam 120, steel floor 131 to be fixed together with wood covering 132 in lap-joint.Connecting element 140 can have various ways, such as, screw etc. for being spirally connected.
Certainly, gap is there is not in order to make floor to contact with bottom cross beam as much as possible, alternatively, when the load-bearing surface for load carrying floor of bottom cross beam does not have depressed part, depressed part or step can also be formed in the end of the bottom of wood covering, for the mating shapes with steel floor and bottom side beams, avoid there is gap between parts.
In addition, in order to strengthen the intensity of underframe, according to another embodiment of the invention, reinforcement longeron can also be set.As shown in Figure 4 and Figure 5, underframe 200 comprises a pair longeron 210, multiple bottom cross beam 220 and floor 230.Floor 230 comprises the steel floor 231 and wood covering 232 that the transverse direction along floor 230 is alternately arranged.The cross-sectional plane of steel floor 231 can be omega type equally, i.e. the cross-sectional plane of the steel floor 231 lower horizontal part 231C that can comprise horizontal part 231A, extend to both sides from the vertical portion 231B of two ends to downward-extension of upper horizontal part 231A and the lower end on even keel from vertical portion 231B.Wood covering 232 is overlapped on the lower horizontal part 231C of the steel floor 231 be adjacent.Wherein, be also provided with the reinforcement longeron 240 longitudinally arranged between a pair bottom side beams 210, namely this reinforcement longeron 240 is between bottom side beams 210, and is parallel to the setting of bottom side beams 210 ground.Strengthen the below that longeron 240 is positioned at the upper horizontal part 231A of steel floor 231, such as, be fixedly connected on the below of the upper horizontal part 231A of steel floor 231 by modes such as welding, for supporting steel floor 231, thus strengthen the intensity of underframe 200 further.
The quantity strengthening longeron can be one, also can be multiple.The position strengthening longeron can be arranged on below the upper horizontal part of any one steel floor.In practice, quantity and the position of strengthening longeron can be determined by the actual strength needed for floor.In general, in the loading process of underframe, the intensity of the zone line on floor is more weak.Therefore, according to a preferred embodiment of the present invention, as shown in Figure 5, underframe 200 can comprise one and strengthens longeron 240, its zone line between a pair bottom side beams 210.Only arrange at the zone line of a pair bottom side beams 210 and strengthen longeron 240, both can ensure the intensity of underframe 200, the quantity strengthening longeron 240 can be reduced again, thus reduce productive costs.
From the above mentioned, between a pair longeron of underframe, be both provided with the reinforcement longeron extended longitudinally, be provided with again multiple bottom cross beam extended transversely.Therefore, strengthen longeron may intersect between a pair longeron with multiple bottom cross beam.According to one embodiment of present invention, strengthen longeron 240 can be provided with multiple opening (not shown), multiple bottom cross beam 220 can be each passed through multiple opening and be connected with a pair bottom side beams 210.Therefore, bottom cross beam 220 connects into entirety with reinforcement longeron 240 and a pair bottom side beams 210, further increases the intensity of underframe 200.
In addition, as shown in Figure 5, only steel floor 231 can be set above reinforcement longeron.The remainder on floor still all adopts wood covering 232.The manufacture difficulty on floor 230 can be reduced like this, lower manufacturing cost.Such as shown in Fig. 5, only arrange one at the zone line that the intensity of underframe is more weak and strengthen longeron 240, the top of this reinforcement longeron 240 arranges steel floor 231, adopts the wood covering 232 of monoblock in the both sides of this steel floor 231.
Certainly, in order to reduce the use of wood covering, the steel floor 331 of longitudinal extension also can be set in other position except strengthening longeron 340, as shown in fig. 6-7.When process costs is lower, holistic cost can be balanced by reducing feed stock cost (namely reducing the use of timber).Particularly, as shown in fig. 6-7, underframe 300 floor 330 that comprises a pair bottom side beams 310, multiple bottom cross beam 320 and be laid on bottom side beams 310 and bottom cross beam 320.Floor 330 can comprise the steel floor 331 and wood covering 332 that the transverse direction along floor 330 is alternately arranged equally.The cross-sectional plane of steel floor 331 can be omega type equally, i.e. the cross-sectional plane of the steel floor 331 lower horizontal part 331C that can comprise horizontal part 331A, extend to both sides from the vertical portion 331B of two ends to downward-extension of upper horizontal part 331A and the lower end on even keel from vertical portion 331B.Bottom cross beam 320 there is depressed part (not shown) on the load-bearing surface of load carrying floor 330, and be provided with between a pair bottom side beams 310 and extend longitudinally and be positioned at the reinforcement longeron 340 of the below of the upper horizontal part 331A of steel floor 331, to strengthen the intensity of underframe 300 as much as possible.The concrete structure of reinforcement longeron 340 of below of the depressed part on the load-bearing surface of bottom cross beam 320 and the upper horizontal part 331A that is positioned at steel floor 331 with reference to the description of above appropriate section, for simplicity, can repeat no more.
In sum, according to the floor that the floor of freight container of the present invention adopts steel wood to be alternately arranged, the use of wood covering is decreased.And the cross-sectional plane of steel floor is omega type, enhance the intensity of steel floor, thus enhance the intensity of underframe.
