The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed description:
Embodiment 1:
Like Fig. 4, the chassis of container 3 shown in 5; Comprise the bottom side beams 300 that is positioned at its both sides; Be positioned at the threshold 301 and front end underbeam 302 at underframe two ends; A plurality ofly be parallel to and be arranged between threshold 301 and the front end underbeam 302 bottom cross beam 303 side by side, all be welded with base angle part 361 at the two ends of threshold 301 and the two ends of front end underbeam 302; Above-mentioned bottom side beams 300, bottom cross beam 303, threshold 301, front end underbeam 302 are welded to connect into a frame body, and wood covering 37 is layed on this frame body, and the position, intermediate portion is supported on the top surface of bottom cross beam 303.Threshold 301 inner sides are provided with downwards and the threshold bending section 3011 of wood covering 37 is carried in its upper surface and concordant being used to of the top surface of bottom cross beam 303; Corresponding; In order to guarantee the smooth of container wood floor 37; Front end underbeam 302 medial extremitys are provided with downwards and the front end underbeam bending section 3021 of wood covering 37 is carried in its upper surface face and concordant being used to of bottom cross beam 303 top surfaces, and the two ends of wood covering 37 ride over respectively on front end underbeam bending section 3021 and the threshold bending section 3011.The upper surface of the top surface of bottom cross beam 303, threshold bending section 3011 upper surfaces, front end underbeam bending section 3021 upper surfaces and base angle part 361 is positioned at same plane; That is to say; The loading height S of this underframe 3 equals the height sum of the height and the wood covering 37 of base angle part 361, adopts under the situation of standard back corner fittings at base angle part 361, and the loading of this underframe height S is low with respect to the loading height K (referring to Fig. 3) of ISO container underframe; Thereby; Use the internal height of freight container of this underframe 3 higher than the internal height of ISO container, under guard box external size and inner length unmodified situation, its corresponding cargo bay is also big.
In conjunction with Fig. 5, Fig. 6, shown in Figure 7; Because the length of threshold 301 and front end underbeam 302 is less than the width of wood covering 37; Thereby; Four vertex angle parts of wood covering 37 must exceed the two ends of threshold 301 and front end underbeam 302 on the container width direction, it exceeds part and is overlapped on the upper surface that is connected base angle part 361.
At present; The thickness of wood covering commonly used is 28mm in the industry, allows ± error of 0.5mm, and the thickness of the employed wood covering of some American-European inland container depots can reach 38mm; 42mm is thick even; On the lower freight container of some requirement of strength, the thickness of its wood covering is then correspondingly less, can be about 25mm simultaneously.Thereby the wood ground 37 that present embodiment is explained structurally requires its basal surface concordant with the upper surface of base angle part 361, and its thickness can be 25mm-38mm, and at some in particular cases, its thickness can thicken to 42mm.At this; Consider that general base angle part 261 all adopts the high base angle part of 118mm that meets the freight container iso standard; So, loading height (surface of base angle part 361 is to the height of the floor upper surface) S=118mm+ (25mm-42mm)=143mm-160mm of the underframe that present embodiment is explained.
General general knowledge by the present technique field can be known; Dull and stereotyped steel floor or corrugated bar floor also can be adopted in the floor; The thickness of general dull and stereotyped steel floor is 2mm-8mm, and the thickness on corrugated bar floor is 8mm-35mm, and then its corresponding loading highly is 120mm-126mm and 126mm-153mm.
(surface of base angle part 361 is to the height of floor upper surface for underframe loading height; Referring to Fig. 5 height S) reduction can cause the reduction of whole underframe intensity; For this reason; Adoptable compensatory approach commonly used is the density and/or increase the sectional area of bottom cross beam, bottom side beams, threshold, front end underbeam etc. of arranging that increases bottom cross beam, but these methods all can cause the increase of cost of manufacture and the increase of underframe deadweight.Adopting yield limit to make framing members such as threshold, front end underbeam, bottom cross beam, bottom side beams greater than the high strength steel of 450Mpa is more useful selection; Needs according to underframe intensity; Can adopt the high strength steel of yield limit selectively greater than 450Mpa; Like the trade mark is the high strength steel of ZJ700W, makes said structure spare.Because adopt high strength steel, the sectional dimension of said structure spare can reduce relatively, can reduce the deadweight of whole underframe thus.
Embodiment 2:

General general knowledge by the present technique field can be known; Dull and stereotyped steel floor or corrugated bar floor also can be adopted in the floor; The thickness of general dull and stereotyped steel floor is 2mm-8mm, and the thickness on corrugated bar floor is 8mm-35mm, under the upper surface that guarantees the floor situation concordant with the upper surface of base angle part; Its corresponding loading highly is equal to the height of base angle part, is generally 118mm.
In the present embodiment; The floor is identical with embodiment 1 with the fit system of front end underbeam and threshold; Reach the front end underbeam and be provided with the front end underbeam bending section that is used for load carrying floor, threshold is provided with the threshold bending section that is used for load carrying floor, and the upper surface of this two bending section is concordant.
Description among material that framing member adopted in the present embodiment such as the embodiment 1 at this, no longer elaborates.
Above-mentioned two embodiment have explained the present invention's two kinds of ultimate attainment situation in use, that is, the surface on floor is concordant with base angle part upper surface and floor upper surface is concordant with base angle part upper surface.In actual use, the upper surface on floor can be between above-mentioned two kinds of situation.
Simultaneously, in actual use, length is that 40 feet or length surpass on 40 feet the freight container; Standing on its underframe have goose neck tunnel, is a burnishing surface for guaranteeing floor upper surface, shown in figure 11; Goose girder 38 upper surfaces of goose neck tunnel are concordant with floor upper surface, simultaneously, consider from the intensity of underframe; This goose girder 38 can adopt the high strength steel of yield limit greater than 450Mpa selectively, is the high strength steel of ZJ700W like the trade mark
The above for the person of ordinary skill of the art, can make other various corresponding changes and distortion according to technical scheme of the present invention and technical conceive, and all these changes and distortion all should belong to the protection domain of the accompanying right of the present invention.
