Connecing, headwall 1 and side wall 3 are installed on underframe.
Wherein, it is connected by fabricated structural shape 4 respectively between headwall 1 with side wall 3 and between headwall 1 with roof 2, solder type
The rectangular area that material 4 is located between headwall 1 and side wall 3 from inner side pad or is formed between headwall 1 and roof 2, headwall 1 with
Being reserved with seam between side wall 3 and between headwall 1 and roof 2 respectively, fabricated structural shape 4 is provided with the projection for filling seam
Position.
Concrete, the fabricated structural shape 4 between headwall 1 and side wall 3 is the first fabricated structural shape, and the first fabricated structural shape is arranged
Boss is the first boss 41, the first boss 41 along the diagonal outwardly convex of the first fabricated structural shape,
One boss 41 is for filling seam reserved between headwall 1 and side wall 3.Meanwhile, the first boss 41 has and headwall 1
The first plane 411 that outer surface flushes, and the second plane 412 flushed with side wall 3 outer surface.
Above-mentioned arrange, first plane 411 and the setting of the second plane 412, it is ensured that the first boss 41 and end
Wall 1 and side wall 3 are generally flush with in outside, it is ensured that the planarization of car body outer surface and aesthetic property.
Further, being welded to connect of the first fabricated structural shape and headwall 1 and side wall 3 for convenience, the first boss 41 has
Have the first inclined-plane 413 forming bevel for welding between headwall 1 end, and and side wall 3 end face between form bevel for welding
Second inclined-plane 414.
Concrete, the side on the first inclined-plane 413 is connected with the first plane 411, and opposite side connects with the end plane of headwall 1
Touching, during welding, wlding is filled in the bevel for welding formed to the first inclined-plane 413 and headwall 1 end, and then after polishing, first is flat
Face 411, weld seam and headwall 1 end face form a plane completed, good looking appearance, it is not necessary to arrange ornamental strip 13, save zero
Number of packages amount, and, simplify structure and technique.
Same, the side on the second inclined-plane 414 is connected with the second plane 412, and opposite side connects with the end plane of side wall 3

Above-mentioned setting, can meet the position characteristics between roof 2 and headwall 1, due to top and the roof 2 of headwall 1
There is between end a certain distance, therefore, the length of fourth plane 422 is set greater than the length of the 3rd plane 421, can
So that forming a complete right angle after having welded between roof 2 with headwall 1, improve aesthetic property.
Further, the second boss 42 has the 3rd inclined-plane 423 forming bevel for welding between headwall 1 end, with
And and roof 2 end face between form the 4th inclined-plane 424 of bevel for welding.
Wherein, the side on the 3rd inclined-plane 423 is connected with the 3rd plane 421, and opposite side contacts with the end plane of headwall 1,
During welding, wlding is filled in the bevel for welding formed to the 3rd inclined-plane 423 and headwall 1 end, then after polishing, and the 3rd plane
421, weld seam and headwall 1 end face form a plane completed, good looking appearance, it is not necessary to arrange ornamental strip 13, save part
Quantity, and, simplify structure and technique.
Same, the side on the 4th inclined-plane 424 is connected with fourth plane 422, and opposite side connects with the end plane of roof 2
Touching, during welding, wlding is filled in the bevel for welding formed to the 4th inclined-plane 424 and roof 2 end, then after polishing, and Siping City
Face 422, weld seam and roof 2 end face form a plane completed.
Meanwhile, the second fabricated structural shape is extruded square tube section, the Surface of profile laminating of the second fabricated structural shape
In the inner surface of headwall 1, the Surface of profile of the second fabricated structural shape another side is by arranging backing plate 21 to fit in the interior table of roof 2
Face.
Further, since the second fabricated structural shape is arranged on the top of car body inner chamber, therefore, in order to prevent the second fabricated structural shape from existing
Fall under self gravitation effect, gripper shoe 22 can be set, meanwhile, in order to avoid gripper shoe 22 in the bottom of the second fabricated structural shape
Taking vehicle body space, gripper shoe 22 can be fitted the surface configuration of headwall 1.
Where like it should be noted that the 3rd inclined-plane 423 can also be arranged on headwall 1, the 4th inclined-plane 424 can also
It is arranged on roof 2, it is not limited to the scheme gone out given in the present embodiment.
Certainly, the shape about the second fabricated structural shape can also be triangle tubing, it is possible to facilitate extruded structure
, it is again not limited to the structure gone out given in the present embodiment.
Further, the inner chamber of the second fabricated structural shape is provided with groove 425 in the position corresponding to the second boss 42, with
The wall thickness making the second fabricated structural shape keeps consistent substantially, beneficially the processing of section bar, reduces the weight of section bar simultaneously.
Further, the second boss 42 is provided with what interior corner with headwall 1 and roof 2 respectively matched at its root
Position, right angle, is i.e. used for and headwall 1 and the Access Division of roof 2 clamping.
Same, offering of position, above-mentioned right angle, it is possible not only to facilitate the second fabricated structural shape and headwall 1 and roof 2
Spacing, convenient processing, furthermore, it is possible to being stuffed entirely with of wlding during convenient welding, it is to avoid the 3rd inclined-plane 423 and the 4th inclined-plane
At 424 grooves formed respectively, wlding is filled not exclusively, causes the pollutant such as rainwater to immerse.
This car body utilizes fabricated structural shape 4 to substitute right angle frame 11 of the prior art, the intensity of fabricated structural shape 4 and resistance to deformation energy
Power is noticeably greater than right angle frame 11, can significantly improve the non-deformability of whole car body, and structural strength is higher, passes through meanwhile
