Description
Technical field
The utility model relates to freight container, is specifically related to a kind of improvement of freight container longitudinal side wall structure.
Background technology
The longitudinal side wall of freight container adopts corrugated board structures usually, and its wave mode cross section helps strengthening the resistance to bending of longitudinal side wall, satisfies the requirement of freight container longitudinal side wall ISO strength test.For a long time, the freight container longitudinal side wall adopts traditional wave mode size with corrugated plating, the corrugated plating hypotenuse is bigger at the projection size I on wave crest plane, D is less for the ripple height, be unfavorable for improving the corrugated plating resistance to bending, make thicker steel plate and the high-intensity material of the essential employing of corrugated plating, could test by ISO.Adopt high-intensity material, can cause the material cost height, be unfavorable for reducing the container material cost; And adopt thicker steel plate, one side to increase rolled steel dosage and increased cost, and increased the casing deadweight on the other hand again, reduced the casing maximum loading, be unfavorable for improving the efficiency of loading of freight container.
Summary of the invention
The technical problems to be solved in the utility model is, the size of rational freight container longitudinal side wall wave mode is provided, the corrugated plating that longitudinal side wall is adopted can substitute the high strength material of former employing with low-intensity material, reaches the purpose that reduces container material cost and casing deadweight.
The technical scheme that the utility model addresses the above problem is, designs a kind of longitudinal side wall structure of freight container, it is characterized in that the shape of cross section of described sidewall is a kind of ripple struction of being made up of a plurality of identical crest 1, hypotenuse 2 and troughs 3.
In the longitudinal side wall structure of above-mentioned freight container, the height between described crest 1 and the trough 3 can be 36＜D≤54mm, and the length that described hypotenuse is projected in described trough plane can be 0≤I≤25, and the thickness of described sidewall corrugated plating is the 0.8-1.2 millimeter.
The longitudinal side wall structure of the freight container that provides by the utility model, scantling of structure by reasonable adjustment corrugated plating wave mode, can make longitudinal side wall adopt low-intensity material to substitute high strength material with corrugated plating, reach the purpose that reduces the container material cost, and adopt the steel plate thinner to test by ISO than conventional wave card, save material, reduced the casing deadweight effectively.Below in conjunction with accompanying drawing, further specify the utility model with a plurality of preferred embodiments.
Description of drawings
Fig. 1 is the front view of the utility model longitudinal side wall structure;
Fig. 2 is the A-A cross-sectional view of Fig. 1;
Fig. 3 is the structural front view of traditional longitudinal side wall;
Fig. 4 is the B-B cross-sectional view of Fig. 3;
Specific embodiment
The longitudinal side wall 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 sm 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 sm is high more, and the resistance to bending of corrugated plating is also strong more.
The tradition longitudinal side wall 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, the longitudinal side wall that the utility model provides is by improving corrugated plating ripple height D, reduce hypotenuse at the projection size I on crest 1 plane with suitable increase crest 1 width B and trough 3 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 longitudinal side wall corrugated plating bending strength equivalence of novel longitudinal sidewall, reach the material that adopts the cheap material of low-intensity grade to substitute high strength grade costliness, reduce the purpose of container material cost, also reach and reduce corrugated plating thickness, alleviate the purpose of box weight.
The novel longitudinal sidewall is 36＜D≤54 millimeter with the span of ripple height D between the crest 1 of corrugated plating and the trough 3, hypotenuse 2 can be according to the thickness of corrugated plating in the value of the projection size I on crest 1 plane, the size of wave height D, crest 1 and trough 3 is suitably chosen, when the height D between crest 1 and trough 3 was taken as 36＜D≤54 millimeter, hypotenuse 2 can be 0≤I≤25mm at the projected length I on crest 1 plane.
In conjunction with Fig. 1～Fig. 4, provide two kinds of longitudinal side walls typical wave mode size of corrugated plating and the comparison of material that traditional longitudinal side wall provides with corrugated plating and the utility model with the mode of tabulating:
| 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 | |
Data as can be seen from table, tradition longitudinal side wall corrugated plating hypotenuse projection size I too big (68 millimeters), ripple height D less (36 millimeters), the corrugated plating thickness T need reach 1.6 millimeters, needs to adopt higher-strength grade steel Corten A (yield strength 35Kg/mm
2), could test by ISO.
Novel longitudinal sidewall corrugated plating P1, reduce hypotenuse size I (15 millimeters) by increasing corrugated plating height D (38 millimeters), suitably increase crest and trough size, 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 longitudinal side wall.
Novel longitudinal sidewall corrugated plating P2, by increasing ripple height D (45 millimeters), reduce hypotenuse projection size I (12 millimeters), suitably increase crest and trough size, increase ripple height D (42 millimeters) simultaneously, 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 longitudinal side wall.
As seen, the novel longitudinal 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, thereby alleviate box weight, improve the purpose of casing maximum loading.
