Wherein, description of reference numerals is as follows: 11, beading; 12, main body; 121, base portion; 122, the first alar part; 123, the second alar part.
The specific embodiment
In order to further illustrate principle of the present utility model and structure, now by reference to the accompanying drawings preferred embodiment of the present utility model is elaborated.
Consult Fig. 2 to Fig. 4, the container roof plate structure that the utility model provides comprises tabular main body 12 and the beading 11 that protrudes out main body 12, and beading 11 is the bar shaped of extending along top board structure Width.Main body 12 comprises that thickness is that base portion 121, the thickness of the first setting value is that the first alar part 122 and the thickness of the second setting value is the second alar part 123 of the 3rd setting value, the second setting value and the 3rd setting value are all greater than the first setting value, and the first alar part 122 and the second alar part 123 are respectively in the both sides of base portion 121 Widths; Beading 11 is across base portion 121, the first alar part 122 and the second alar part 123, and the two ends wave head part of beading 11 lays respectively at the first alar part 122 and the second alar part 123.
In this top board structure, the thickness of two side portions is greater than the thickness of centre portion, and the thickness that holds damageable wave head part is larger, has effectively strengthened the rust stable of the resistance to collision ability of rapid wear part, reduces its damage rate, reduces service expenditure.By the differentiation of top plate thickness, in guaranteeing top board operating needs, can reduce the weight of top board, thus the deadweight that can alleviate freight container.
Wherein, preferably, the first setting value is 1.2mm ~ 1.6mm, and as 1.2mm, 1.4mm, 1.5mm, 1.6mm etc., the second setting value and the 3rd setting value are 2.0mm ~ 3.0mm, as 2.0mm, 2.3mm, 2.5mm, 3.0mm etc.The existing top board structure thickness of Thickness Ratio of wave head part place, the two ends alar part 122,123 of beading 11 is large, increases the intensity of wave head part; And simultaneously, the Thickness Ratio of centre portion is existing little, therefore, the weight of the whole plate of top board structure can't increase because of the intensity of strengthening wave head part.In the present embodiment, the second setting value equates with the 3rd setting value, and the first alar part is identical with the thickness of the second alar part, the intensity being consistent.In other embodiments, the two also can be set to different-thickness according to the difference of practical working situation.
More preferably, the length that beading 11 is positioned at the first alar part 122 and the second alar part 123 parts is all not less than 300mm.According to damaged condition in existing top board structure, be to be generally the most damageable part within the scope of the 300mm of beading two ends, and this part compacting attenuation is the most serious, stress is also the most concentrated, the utility model, by the top plate thickness thickening of this part, improves intensity, reduces and damages phenomenon.The width of the first alar part 122 and the second alar part 123 is correspondingly greater than 300mm, the upper limit width of the first alar part 122 and the second alar part 123 can be set according to actual conditions, preferably as far as possible little in the situation that guaranteeing beading damageable zone thickness, to alleviate the overall weight of top board structure, save material, reduce costs.Take the thickness of base portion 121 as 1.6mm, the thickness of the first alar part 122 and the second alar part 123 is example at 2.0mm ~ 3.0mm, by the ratio of the first alar part 122, the second alar part 123 and base portion 121 is rationally set, can make the gross weight of whole plate be less than the top board of existing overall 2.0mm thickness.
Top board structure of the present utility model can adopt laser assembly solder plate, and the first alar part 122, the second alar part 123 are fixedly connected with by laser assembly solder with base portion 121.The first alar part 122, the second alar part 123 in the time splicing, make three's upper surface concordant with base portion 121, can prevent top board structure surface area water, and specious.On the laser assembly solder plate completing in splicing, suppress multiple beadings 11 again along top board structure length direction, wherein, beading 11 is the bar shaped of extending along top board structure Width.More preferably, base portion 121, the first alar part 122 and the second alar part 123 are monoblock steel plate respectively, the preseting length that the length of steel plate is top board structure; Adding man-hour, can on the former material of laser assembly solder plate (volume), suppress beading, then cutting off by the preseting length of top board structure, like this without the splicing of carrying out polylith top board, simplified processing process, reduces weld seam quantity.Certainly, in other embodiments, the form that also can adopt plurality of steel plates to splice along its length.Along with the development of laser assembly solder technology, the application of laser assembly solder plate (volume) will be more and more universal, do not wait the cost of plate iron (volume) also can constantly to decline, the utility model container roof plate structure is in having promoted product design, and its integrated cost also will be lower than existing top board structure.
Container roof plate structure of the present utility model can also be base portion 121, the first alar part 122 and the overall integrated structure of the second alar part 123, and the material of top board can adopt as plastics, aluminum alloy etc.
The utility model also provides a kind of freight container, adopts container roof plate structure as above.In this freight container, improve the product design of top board structure, reduce and damage, and by the appropriate design to top board structure, can also make container body weight saving.
These are only better possible embodiments of the present utility model, and unrestricted protection domain of the present utility model, the equivalent structure that all utilization the utility model specification sheetss and accompanying drawing content have been done changes, and is all included in protection domain of the present utility model.
