Specific embodiment
Usually freight container is to be formed by pair of sidewalls, door end, front end, top board, floor and underframe.Undercarriage structure and floor mutual group become the carrying structure of goods in the case, are the main force structures of freight container, and its material consumption and material cost proportion in each big parts of freight container is very high.Thereby optimize Undercarriage structure and panel material with improvement, to reducing tank material cost and raising casing maximum loading, meaning is very big.The pair of sidewalls of freight container adopts corrugated plating as wallboard, has increased the intensity of sidewall wallboard, satisfies the requirement of freight container ISO strength test.Optimize the wave mode size of corrugated plating, can make the sidewall corrugated plating adopt thinner steel plate and than low-intensity material, guarantee and the equivalence of traditional sidewall corrugated plating intensity, satisfy the ISO test, adopt the optimization corrugated board structures can further reduce tank material cost and casing deadweight.
Fig. 1, Fig. 2, Fig. 3, Fig. 4 have represented the constituent elements structure of freight container of the present invention: promptly wall box 1A (two), door are held 2A, front end 3A, top board 4A, Undercarriage structure 5A and steel floor 5, and wherein Undercarriage structure, floor and sidewall are the objects that the present invention improves and optimizes.
As shown in Figure 5, chassis of container structure of the present invention mainly is made up of two foundation curb girders 1, some longerons 2, some bottom cross beams 3, weld with the side of bottom side beams 1 respectively at bottom cross beam 3 two ends, and longeron 2 intersects and welding with bottom cross beam 3, constitutes a complete rigid frame structure.Compare with traditional regular general cargo general purpose container Undercarriage structure (shown in Figure 10), its difference is, novel Undercarriage structure has increased some longerons 2, thereby guaranteeing under the prerequisite of underframe by the ISO test, the bottom cross beam spacing L1 of novel Undercarriage structure can be far longer than the bottom cross beam spacing L3 of traditional Undercarriage structure, thereby the quantity of bottom cross beam is significantly reduced.
As Fig. 5, shown in Figure 6, some longerons 2 intersect and welding with crossbeam of some ends 3, and longeron 2 distributes along the length direction of bottom cross beam 3.Test by ISO with less sectional dimension H2, B2 and thin wall thickness T 2 for guaranteeing longeron, girder space L2 should be not more than 600mm, be preferably and be not more than 300mm, preferably be not more than the width 180mm of container floor test wheel 4, making has at least a longeron directly to support test wheel 4, bottom cross beam spacing L1 should select suitably simultaneously, should not be too big, the shape of cross section of bottom cross beam 3 and longeron 2 can be: L type, I type, T type, U type, C type or frame type, the cross-sectional plane of bottom cross beam 3 and longeron 2 can be shape identical shaped or inequality.
It is multiple that longeron 2 and bottom cross beam 3 bonded assembly versions have, and the invention provides as Fig. 7, two kinds shown in Figure 8:
A. the groove that perforate 6 or opening make progress on bottom cross beam 3, longeron 2 pass hole 6 and intersect and welding with bottom cross beam 3;
B. longeron 2 and the two adjacent bottom cross beams 3 between employing and the two adjacent bottom cross beams 3 are welded to connect.
As Fig. 6, shown in Figure 9, bottom side beams 1, longeron 2, bottom cross beam 3 and steel floor 5 welding, the integral body and the loading ground of a rigidity of formation.After steel floor 5 welds with longeron 2, bottom cross beam 3, increase the bending strength of longeron and bottom cross beam, helped reducing its sectional dimension, reduced weight.According to the present invention, steel floor 5 can adopt thickness to be not more than 4 millimeters steel plate.
As Figure 11, shown in Figure 12, on the bottom cross beam of traditional Undercarriage structure, need to lay wood covering 8, constitute the loading ground of freight container.
Figure 13 is novel Undercarriage structure bottom cross beam 3 and being connected of steel floor 5, and Figure 14 is traditional Undercarriage structure bottom cross beam 7 and being connected of wood covering 8.The advantage of novel Undercarriage structure is as follows:
A. the height H 1 of the bottom cross beam 3 of novel Undercarriage structure more helps the bottom cross beam bending resistance greater than the height H 3 of the bottom cross beam 7 of traditional Undercarriage structure so that the section material of bottom cross beam 3 distributes;
B. bottom cross beam 3 is welded as a whole with steel floor 5, and the material of the near zone of steel floor 5 and bottom cross beam 3 welding will improve the bending strength of bottom cross beam 3 greatly;
Thereby under the condition by the ISO test, the wall thickness T 1 of bottom cross beam 3 is thinner, generally be about 2～3 millimeters, and the wall thickness T 3 of bottom cross beam 7 is thicker, is generally 4～4.5 millimeters.The base width B 1 of bottom cross beam 3 is close with the base width B 3 of bottom cross beam 7, and the height H 1 of bottom cross beam 3 is greater than the height H 3 of bottom cross beam 7, but comprehensive, the weight of bottom cross beam 7 will be bigger than the weight of bottom cross beam 3.
Novel steel floor is a general steel plate, with wood covering relatively: in light weight, cost is low, and the market supply of material is stable.Novel steel floor substitutes traditional wood covering, has reduced tank material cost and deadweight, and has avoided the influence of wood covering short supply to container production and cost.
Sidewall as another major part of freight container, must possess certain resistance to bending with corrugated plating, could pass through longitudinal side wall ISO strength test.The resistance to bending of corrugated plating is decided by that the yield strength m corrugated plating bending resistant section modulus W of corrugated plating bending resistant section modulus W and corrugated plating material is high more, and the resistance to bending of corrugated plating is strong more, and YIELD STRENGTH m is high more, and the resistance to bending of corrugated plating is also strong more.
The tradition sidewall is too small with corrugated plating ripple height D, makes that its bending resistant section modulus W is less, and hypotenuse is excessive at the projection size I on wave crest plane, makes material not be distributed in the crest and the trough of corrugated plating more, thereby makes its bending resistant section modulus W less.So the conventional wave card need adopt the material of thicker steel plate and higher-strength grade, could pass through the ISO strength test.
Under the prerequisite that satisfies freight container iso standard dimensional characteristic, novel sidewall passes through to improve corrugated plating ripple height D with corrugated plating, reduce hypotenuse at the projection size I on wave crest plane with suitable increase crest width B and trough width C, increase of the distribution of corrugated plating material, reach the purpose that improves corrugated plating bending resistant section modulus W at crest and trough.Thereby guarantee corrugated plating and the traditional sidewall corrugated plating bending strength equivalence of novel sidewall, reach the material that adopts the cheap material of low-intensity grade to substitute high strength grade costliness, the purpose that reduces the container material cost, also reach and reduce corrugated plating thickness, alleviate the purpose of box weight.
Novel sidewall is 36＜D≤54 millimeter with the span of the ripple height D of corrugated plating, and hypotenuse is I=0～25 millimeter in the span of the projection size I on wave crest plane.
In conjunction with Figure 15～Figure 18, following table provides traditional sidewall corrugated plating and two kinds of novel the sidewalls typical wave mode size of corrugated plating and comparisons of material:
| Wave mode and material | Wave mode size (mm) | The corrugated plating material | ||||||
| Crest B | Trough C | Ripple height D | Hypotenuse I | Ripple thickness of slab T | Title material | Yield strength Kg/mm 2 | ||
| The conventional wave card | 72 | 70 | 36 | 68 | 1.6 | Corten A | 35 | |
| Novel corrugated plate | P1 | 78 | 78 | 38 | 15 | 1.2 | SS41 | 25 |
| P2 | 78 | 78 | 45 | 12 | 1 | SS41 | 25 | |
From table data as can be seen, traditional sidewall is with corrugated plating hypotenuse size I too big (68 millimeters), ripple height D less (36 millimeters), the corrugated plating thickness T need reach 1.6 millimeters, and adopts higher-strength grade steel Corten A (yield strength 35Kg/mm
2), could test by ISO.
Novel sidewall corrugated plating P1 by increasing ripple height D (38 millimeters), reduces hypotenuse size I (15 millimeters), suitably increases crest and trough size, and the corrugated plating thickness T adopts 1.2 millimeters, adopts than low-intensity grade steel SS41 (yield strength 25Kg/mm
2), can guarantee its bending strength and the corrugated plating equivalence of traditional sidewall.
Novel sidewall corrugated plating P2 reduces hypotenuse size I (12 millimeters) by increasing ripple height D (45 millimeters), suitably increases crest and trough size, and the corrugated plating thickness T adopts 1 millimeter, adopts than low-intensity grade steel SS41 (yield strength 25Kg/mm
2), can guarantee its bending strength and the corrugated plating equivalence of traditional sidewall.
As seen, novel sidewall by adjusting wave height D and hypotenuse at the projection size I on wave crest plane, can realize adopting low-intensity material to substitute high strength material with corrugated plating, reduces the purpose of container material cost; Also can realize reducing the corrugated plating thickness of slab, the economical with materials consumption, thus alleviate box weight.
More than by adopting novel Undercarriage structure, steel floor and novel sidewall corrugated plating, make this novel steel floor freight container reduce the container material cost, reduced the casing deadweight and improved maximum loading, and avoided the influence of wood covering short supply container production and cost.
