Detailed ways

Below in conjunction with accompanying drawing, the utility model is further elaborated.

Embodiment 1: As shown in FIG. 1A to FIG. 1E , the bottom structure of the container in this embodiment 1 includes an underframe 1 and a floor 2 laid on the underframe. The underframe 1 includes two parallel and longitudinally arranged bottom sides Beams 11 and 12, several bottom beams 13 horizontally arranged between the two bottom side beams 11, 12, the chassis 1 and the floor 2 laid on the chassis 1 together constitute the load-bearing structure of the container and the goods in the box.

Wherein, the floor 2 includes a wooden floor 21 and a steel floor 22 arranged at intervals on the bottom beam 13. The steel floor includes a base body 221 with an inverted U-shaped cross section, and the inverted U-shaped base body 221 extends horizontally at the opening. The two horizontal supports 222, 223 are generally called "Ω" type in the industry, and the two horizontal supports 222, 223 are fixedly connected with the upper flange 131 (shown in Figure 1E) of the bottom beam 13, and are located in the middle of the width direction of the container. The floor is wooden floor 211.

Compared with the existing container underframe that uses wooden floors, the container bottom structure of the utility model adopts the combination of steel and wood floors, and the added steel floor reduces the use of wooden floors correspondingly. The steel floor is pressed into "" Ω" type, the thickness is adapted to the thickness of the wooden floor, so that the upper surface of the entire floor is flush. The steel floor 22 and the wooden floor 21 are arranged on the bottom beam 13 at intervals, and the width is about 100mm-170mm. The horizontal supports 222, 223 of the steel floor 22 are welded to the upper wing 131 of the bottom cross beam, forming a rigid whole of the whole underframe and increasing the strength of the underframe. And the wooden floor 21 is directly connected with the bottom beam 13 .

Further, as shown in Figure 1E, in order not to increase the weight of the container due to the use of the steel floor, in addition to the steel floor 22 being formed by pressing a thin steel plate, the bottom beam of the container is also designed, that is, in addition to the wide bottom beam (in the figure (not shown), the width B1 of the upper wing plate 131 of other bottom beams 13 is smaller than the width B2 of the lower wing plate 132, thereby reducing the use of materials and facilitating the full utilization of materials.

Embodiment 2: As shown in Figures 2A to 2D, the bottom structure of the container in Embodiment 2 includes an underframe 1 and a floor 2 laid on the underframe, and the underframe 1 includes two parallel and longitudinally arranged bottom sides Beams 11 and 12, several bottom beams 13 horizontally arranged between the two bottom side beams 11, 12, the chassis 1 and the floor 3 laid on the chassis 1 together constitute the load-bearing structure of the container and the goods in the box.

Wherein, the floor 3 includes a wooden floor 31 and a steel floor 32 arranged at intervals on the bottom crossbeam 13. The structure of the steel floor 32 is the same as that of Embodiment 1, that is, it includes a base 321 with a substantially U-shaped cross-section, and the base 321 faces horizontally. The two horizontal supports 322 and 323 extending in the same direction are generally referred to as “Ω” in the industry, and the two horizontal supports 322 and 323 are fixedly connected to the upper wing plate 131 of the bottom beam 13 (shown in FIG. 1E ). The difference from Embodiment 1 is that in Embodiment 2, the floor located in the middle of the width direction of the container is a steel floor 324 .

Compared with the existing container underframe that uses wooden floors, the container bottom structure of the utility model adopts the combination of steel and wood floors, and the added steel floor reduces the use of wooden floors correspondingly. The steel floor is pressed into "" Ω" type, the thickness is adapted to the thickness of the wooden floor, so that the upper surface of the entire floor is flush. The steel floor 32 and the wooden floor 31 are arranged on the bottom beam 13 at intervals, and the width is about 100mm-170mm. The two horizontal supports 322, 323 of the steel floor 32 are welded and connected with the upper wing 131 of the bottom beam, forming a rigid whole of the whole underframe and increasing the strength of the underframe. And the wooden floor 31 is directly connected with the bottom beam 13 .

Embodiment 3: The container of the present utility model comprises a pair of side walls, a door end, a front end, a top plate and a bottom structure, and it is characterized in that the bottom structure of the container includes an underframe and a floor laid on the underframe, and the underframe includes two A bottom side beam arranged parallelly and longitudinally, and a plurality of bottom cross beams arranged transversely between the two bottom side beams.
