The specific embodiment

In order to further illustrate principle of the present utility model and structure, now by reference to the accompanying drawings preferred embodiment of the present utility model is elaborated.

Refer to Fig. 4 to Fig. 6, the utility model provides a kind of chassis of container, and chassis of container comprises two bottom side beams 1, front beam 2, back end beam 3, many foundation crossbeam 4 and steel floor 5.

The symmetrical longitudinal arrangement of bottom side beams 1, two bottom side beams 1, the structure of bottom side beams 1 and the bottom side beams of prior art 1 ' not difference, can directly adopt the bottom side beams 1 of prior art ' the save trouble of transformation.

Front beam 2 connects the end of two foundation curb girder 1 the same sides simultaneously, and the structure of front beam 2 and the front beam of prior art 2 ' not difference can directly adopt the front beam 2 of prior art ' the save trouble of transformation.

Back end beam 3 connects the other end of two foundation curb girder 1 the same sides simultaneously, and the back end beam 3 of back end beam 3 structures and prior art ' not difference can directly adopt the back end beam 3 of prior art ' the save trouble of transformation.

Bottom cross beam 4, bottom cross beam 4 is fixed between two bottom side beams 1 at certain intervals.In the present embodiment, the general C type bottom cross beam that adopts of the bottom cross beam 4 of steel floor 5 position while weldings, so that the welding between polylith floor connects, the bottom cross beam 4 of other non-butt weld positions is L-type structure.

Steel floor 5, steel floor 5 covers on bottom cross beam 4, steel floor 5 comprises a plurality of steel floors unit 51 of longitudinal arrangement splicing, is arranged at intervals with the reinforced rib 511 of many longitudinal extensions on described steel floor unit 51, and the direction of reinforced rib 511 is vertical with the direction of bottom cross beam 4.The effect of reinforced rib 511 is the intensity that increases steel floor 5, just can reduce like this thickness of steel floor 5 in the situation that of same intensity.In the present embodiment, the reinforced rib 511 on adjacent described steel floor unit 51 is connected to each other.Between a plurality of steel floors unit 51, interconnected benefit is between the reinforced rib 511 that can make on each steel floor unit 51, to connect the intensity of further reinforcement steel floor 5.In the present embodiment, the direction of described reinforced rib 511 is vertical with the direction of described bottom cross beam 4.Both orthogonal situations identical with respect to both directions can further be strengthened intensity like this.In the present embodiment, reinforced rib 511 is a part for steel floor unit 51 formation that raises up.By steel floor 5, convexed to form that relatively manually to add the mode of reinforced rib 511 convenient, make also simpler.In other embodiments, reinforced rib 511 also can be recessed to form downwards for a part for steel floor 5, and reinforced rib 511 can also be directly directly set on smooth steel floor 5.Steel floor can also be horizontally-spliced structure or laterally longitudinally mix splicing construction, horizontally-spliced steel floor structure, and steel floor at least comprises two floor unit, floor splicing welding joint just only has one like this, can adopt that automatic welding is disposable to be completed.

The two ends of the reinforced rib 511 of steel floor 5 can be open architectures, also can be enclosed construction, the two ends that Open architecture refers to reinforced rib 511 are not connected with the edge at the two ends of steel floor unit 51, and referring to reinforced rib 511, enclosed construction runs through whole steel floor unit 51, enclosed reinforced rib 511 can be with elongated beading, can be also that several closed at both ends formula beading alignment are arranged.

Refer to Fig. 6 and Fig. 7, in the present embodiment, projection or leg-of-mutton projection that reinforced rib 511 is circular arc, in other embodiments, the convex shape of reinforced rib can arrange arbitrarily as required.General 3 ~ 6mm the steel plate of selecting of steel floor, the height H of reinforced rib 511 outstanding steel floor substrates is 5 ~ 15mm.Steel floor is thinner, and floor beading height is higher, and the spacing of floor beading is closeer, and the bottom cross beam spacing of corresponding bottom support is also closeer.Because less reinforced rib is only set on steel floor, can play the object that improves steel floor intensity and planeness, the relatively flat steel floor structure of the rolled steel dosage of reinforced rib steel floor is not significantly increased, and due to steel floor strength increase, can also reduce steel floor thickness, and/or increase the spacing of bottom cross beam, reduce the quantity of bottom cross beam, and then reduce steel floor steel use amount, reduce costs.

Preferentially, steel floor thickness 3 ~ 5mm, the outstanding substrate height of reinforced rib is 5 ~ 10mm, and reinforced rib spacing is 50 ~ 100mm, and the spacing of corresponding bottom cross beam is 200 ~ 250mm, because of rational steel floor reinforcing rib structure, and the spacing setting of corresponding rational bottom cross beam, the underframe weight of this freight container and the weight of conventional wood covering are basic identical, and cost is significantly reduced, and service life is longer compared with wood covering, be more conducive to be accepted by client.In other embodiments, concrete scope is also can be as required different and adjust, and at this, does not repeat.

Refer to Fig. 8 to Figure 10, in the present embodiment, the protruding top of the reinforced rib 511 contacting with bottom side beams 1, front beam 2 or back end beam 3 extends to form weld part 512 to bottom side beams 1, front beam 2 or back end beam 3.Because the bossing of reinforced rib 511 does not contact with bottom side beams 1, front beam 2 or back end beam 3, the welding operation of this part and quality control are had to larger difficulty, and the present embodiment in when welding by weld part 512 bendings being supported to the welding operation of the bossing and bottom side beams 1, front beam 2 or the back end beam 3 that weld to improve reinforced rib 511 on bottom side beams 1, front beam 2 or back end beam 3.Because these weld part 512 sizes are less, during welding, only by hammering, can complete bending, convenient to operation.

The utility model also provides a kind of freight container, and freight container comprises above-mentioned chassis of container.

Because underframe only changes on floor, so not needing to carry out too much extra transformation, freight container just can not adapt to, therefore underframe of the present utility model can be suitable for the freight container of prior art.

In sum; the utility model by arranging reinforced rib on steel floor; improve the intensity of steel floor, thereby reduced the density of thickness and the bottom cross beam of steel floor, and then reduced manufacturing cost; and the surface evenness of steel floor is better; be easier to be accepted by client, be conducive to applying of steel floor freight container, finally substitute wood covering; and then realization solves timber resources, the object of protecting the global environment.

The foregoing is only better possible embodiments of the present utility model, and unrestricted protection domain of the present utility model.Every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification sheets and accompanying drawing content to do, or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
