Detailed ways

In order to further illustrate the principle and structure of the utility model, the preferred embodiments of the utility model will be described in detail in conjunction with the accompanying drawings.

Please refer to FIG. 4 to FIG. 6 , the utility model provides a container underframe, which includes two bottom side beams 1 , a front end beam 2 , a rear end beam 3 , a plurality of bottom beams 4 and a steel floor 5 .

Bottom side beam 1, the two bottom side beams 1 are symmetrically arranged longitudinally, the structure of bottom side beam 1 is no different from the bottom side beam 1′ of the prior art, and the bottom side beam 1′ of the prior art can be directly used to save the need for reconstruction. trouble.

The front end beam 2 is connected to one end of the same side of the two bottom side beams 1 at the same time. The structure of the front end beam 2 is not different from the front end beam 2' of the prior art, and the front end beam 2' of the prior art can be directly used to save the need for transformation. trouble.

The rear end beam 3 is connected to the other end of the same side of the two bottom side beams 1 at the same time. The structure of the rear end beam 3 is not different from that of the prior art rear end beam 3′, and the prior art rear end beam 3′ can be directly adopted Save yourself the hassle of remodeling.

The bottom beam 4 is fixed between the two bottom side beams 1 at a certain interval. In this embodiment, the bottom beam 4 at the weld position of the steel floor 5 generally adopts a C-shaped bottom beam to facilitate the tailor welding connection between multiple floors, and the bottom beam 4 at other non-butt weld positions is an L-shaped structure.

The steel floor 5, the steel floor 5 is covered on the bottom beam 4, the steel floor 5 includes a plurality of steel floor units 51 arranged longitudinally and spliced, and the steel floor units 51 are provided with a plurality of longitudinally extending reinforcing ribs 511 at intervals, and the reinforcing ribs The direction of 511 is perpendicular to the direction of bottom beam 4. The function of the reinforcing rib 511 is to increase the strength of the steel floor 5, so that the thickness of the steel floor 5 can be reduced under the same strength. In this embodiment, the reinforcing ribs 511 on adjacent steel floor units 51 are connected to each other. The advantage of interconnecting multiple steel floor units 51 is that the reinforcing ribs 511 on each steel floor unit 51 can be connected to further strengthen the strength of the steel floor 5 . In this embodiment, the direction of the reinforcing rib 511 is perpendicular to the direction of the bottom beam 4 . In this way, the strength can be further strengthened when the two are perpendicular to each other relative to the same direction of the two. In this embodiment, the reinforcing rib 511 is formed by protruding upward from a part of the steel floor unit 51 . It is more convenient and easier to manufacture than manually adding reinforcing ribs 511 by protruding from the steel floor 5 . In other embodiments, the reinforcing rib 511 can also be formed by a part of the steel floor 5 being recessed downward, and the reinforcing rib 511 can also be directly provided on the flat steel floor 5 . The steel floor can also be a horizontal splicing structure or a horizontal and vertical hybrid splicing structure. The horizontal splicing steel floor structure includes at least two floor units. In this way, there is only one floor splicing weld, which can be completed at one time by automatic welding.

The two ends of the reinforcing rib 511 of the steel floor 5 can be an open structure or a closed structure. The open structure means that the two ends of the reinforcing rib 511 are not connected to the edges of the two ends of the steel floor unit 51, while the closed structure It means that the reinforcing rib 511 runs through the entire steel floor unit 51 , and the closed reinforcing rib 511 may be a full-length bead, or a plurality of closed bead with both ends arranged in alignment.

Please refer to FIG. 6 and FIG. 7 , in this embodiment, the reinforcing rib 511 is an arc-shaped protrusion or a triangular protrusion, and in other embodiments, the protrusion shape of the reinforcing rib can be arbitrarily set as required. The steel floor generally chooses 3~6mm steel plate, and the height H of the reinforcing rib 511 protruding from the steel floor substrate is 5~15mm. The thinner the steel floor, the higher the height of the floor beads, the closer the spacing of the floor beads, and the closer the spacing of the bottom beams corresponding to the bottom support. Because only small reinforcing bars are set on the steel floor, the strength and flatness of the steel floor can be improved. The steel consumption of the reinforced steel floor is not significantly increased compared with the flat steel floor structure, and due to the increase in the strength of the steel floor, It is also possible to reduce the thickness of the steel floor, and/or increase the spacing of the bottom beams, reduce the number of bottom beams, thereby reducing the steel consumption of the steel floor and reducing costs.

Preferentially, the thickness of the steel floor is 3~5mm, the height of the reinforcing ribs protruding from the base plate is 5~10mm, the spacing of the reinforcing ribs is 50~100mm, and the spacing of the corresponding bottom beams is 200~250mm, due to the reasonable structure of the steel floor reinforcing ribs, and the corresponding With a reasonable spacing between the bottom beams, the weight of the bottom frame of the container is basically the same as that of the conventional wooden floor, the cost is greatly reduced, and the service life is longer than that of the wooden floor, which is more conducive to being accepted by customers. In other embodiments, the specific range can also be adjusted according to different needs, which will not be repeated here.

Please refer to Fig. 8 to Fig. 10, in this embodiment, the most top of the rib 511 that is in contact with the bottom side beam 1, the front end beam 2 or the rear end beam 3 faces toward the bottom side beam 1, the front end beam 2 or the rear The end beam 3 extends to form a welding portion 512 . Since the raised part of the rib 511 is not in contact with the bottom side beam 1, the front end beam 2 or the rear end beam 3, the welding operation and quality control of this part are relatively difficult. 512 is bent against the bottom side beam 1 , the front end beam 2 or the rear end beam 3 for welding to improve the welding operation between the raised portion of the rib 511 and the bottom side beam 1 , the front end beam 2 or the rear end beam 3 . Due to the small size of the welding portion 512, the bending can be completed only by hammering during welding, and the operation is convenient and quick.

The utility model also provides a container, which includes the above-mentioned container bottom frame.

Since the underframe only changes on the floor, the container can be adapted without too many additional modifications, so the underframe of the present invention can be adapted to the container of the prior art.

In summary, the utility model improves the strength of the steel floor by providing reinforcing ribs on the steel floor, thereby reducing the thickness of the steel floor and the density of the bottom beam, thereby reducing the manufacturing cost, and the surface smoothness of the steel floor is more Well, it is easier to be accepted by customers, which is conducive to the promotion and application of steel floor containers, and eventually replaces wooden floors, thereby achieving the purpose of solving wood resources and protecting the global environment.
