When further technical scheme is to lay longeron and arrange reinforcement, place gap according to the reserved base plate of base plate thickness.
When further technical scheme is combination frame, enforcement pad site solid welding is fixed.
When further technical scheme is to lay longeron, enforcement pad site solid welding is fixed；The solid welding of pad site is implemented fixed during described layout reinforcement.
Further technical scheme carries out integral solder according to following steps after being layout reinforcement:
A. implement longeron termination to weld with the pad position of bezel contact position；
B. implement reinforcement termination to weld with the pad position of longeron contact position；
C. implement reinforcement termination to weld with the pad position of bezel contact position.
Further technical scheme is step a is implement two terminations of each longeron to weld with the pad position of bezel contact position simultaneously.
Further technical scheme is step b is implement reinforcement termination to weld with the pad position of each longeron contact position simultaneously.
Further technical scheme is step c is implement reinforcement termination to weld with the pad position of two limit contact positions of frame simultaneously.
Further technical scheme carries out integral solder after being layout reinforcement is two-sided welding, and each welding sequence of described two-sided welding is identical.
Further technical scheme is placement base plate is fill in base plate by sectionally assembled or full slice system.
Compared with prior art, the invention has the beneficial effects as follows: the present invention, by changing the conventional assemble sequence of cargo floor assembly, reaches space for the creativity, improve welding operation environment, and then improve the purpose of welding quality.The present invention proposes more efficiently welding technique, further ensures the intensity of welding, effectively prevents the concentration of local of welded stress, reduces welding deformation itself, improves overall non-deformability.

Detailed description of the invention
All features disclosed in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
This specification (include any accessory claim, summary and accompanying drawing) disclosed in any feature, unless specifically stated otherwise, all can by other equivalences or there is the alternative features of similar purpose replaced.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in detail.
As shown in Figure 1 and Figure 2, according to one embodiment of present invention, the open a kind of engineering cargo floor general assembly of the present embodiment and welding method, the present embodiment is by changing the conventional assemble sequence of cargo floor assembly, reach space for the creativity, improve welding operation environment, and then improve the purpose of welding quality.Concrete, as it is shown in figure 1, the present embodiment engineering cargo floor general assembly and welding method are under assembled tool specification, lorry engineering cargo floor assembly puts into assembling, the first step successively by the order of 1～5, combines frame 1；Second step, lays longeron 2；3rd step, arranges reinforcement 3；4th step, places base plate 4；5th step, installs adnexa 5.
Wherein, it is preferred that the present embodiment places gap when laying longeron 2 and arranging reinforcement 3 according to the reserved base plate of base plate thickness.
At the first step, second step, it is fixed that the 3rd step three step implements the solid welding of pad site respectively.Concrete, when self-indulgent beam and layout reinforcement, place gap according to the reserved base plate of base plate thickness.The solid welding of pad site is implemented fixed during combination frame.The solid welding of pad site is implemented fixed when laying longeron；The solid welding of pad site is implemented fixed during described layout reinforcement.
Further preferred embodiment, as in figure 2 it is shown, in the present embodiment on jig, the assembly after 1,2,3 step combinations is implemented integral solder by a → b → c position order, wherein, aa, bb, cc position is double welds simultaneously.
Concrete, the present embodiment carries out integral solder according to following steps after arranging reinforcement:
A. implement longeron termination to weld with the pad position of bezel contact position；
B. implement reinforcement termination to weld with the pad position of longeron contact position；
C. implement reinforcement termination to weld with the pad position of bezel contact position.
Preferably, a and a position welding in Fig. 2, it is and implements two terminations of each longeron simultaneously and weld with the pad position of bezel contact position.When there being two longerons, two longeron terminations that the two ends of two longerons are had altogether are welded with corresponding bezel contact position simultaneously.
B and b position welding in Fig. 2, is enforcement reinforcement termination simultaneously and welds with the pad position of two face contact positions of a longeron with each longeron contact position and reinforcement termination.As having two longerons, the reinforcement termination contact site corresponding with the two sides of another longeron, corresponding contact site, reinforcement termination, the two sides of one of them longeron welds simultaneously.
C and c position welding in Fig. 2, is enforcement reinforcement termination simultaneously and welds with the pad position of two limit contact positions of frame.As seen from Figure 2, wherein the two limit of frame is two symmetrical limits, and it is parallel with longeron.
After one face of the assembly that frame, longeron and reinforcement are assembled into has been welded, overturn assembly, weld another side by abovementioned steps, mode, it is achieved the two-sided welding of reinforcement termination and frame and longeron.
As preferred embodiment, the present embodiment is when placing base plate, it is possible to adopts and sectionally assembled fills in base plate, it would however also be possible to employ full slice system fills in base, fills in base plate adjustment and all postpones, welds in the usual way.Adnexa installed by welding such as mud guard bearing, profile lamp socket, rope hook etc. on request again.Thus the reliability of cargo floor assembly processing technology can be improved, improve lifting load-bearing ability, technique, ensure that the structural strength of engineering cargo floor.
