The specific embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
A kind of rib board pulling method, it comprises following step:
The blanking and the making of vertical bone; Check vertical bone hookup wire; Check vertical bone setting accuracy; Check the floor cutting accuracy; Floor end opening channel-section steel is installed; Floor is penetrated vertical bone; Determine that welding process welds.
Below method of operation in each step and technological requirement are carried out detailed narration respectively.
1, at first in the blanking and manufacturing process of vertical bone, after web and panel blanking finish, the fairing of should polishing of panel free edge and end face.Accuracy standard in this process is as follows:
The squareness of web and panel :≤± 2.0mm (shown in Figure 5)
Centerline deviation between web and the panel :≤± 1.5mm
Panel and web weld together are formed the T section bar,
T section bar and other steel plate the squareness in when welding≤± 1.0mm
T section bar panel out-of-flat≤± per 2 meters of 1.0mm
T profile flange straightness accuracy≤± 1.5mm
After the panel of T section bar and the web welding completion, need carry out firer's correction.
2, in the process of checking vertical bone hookup wire, vertical bone hookup wire on base plate, outside plate and the longitudinal wall should be on the basis of reference high precision flame planer line, check line with the steel band of correctly putting on spacing of longitudinals, and vertical bone hookup wire dimension limit is ± 1mm.
3, will guarantee build-up tolerance in specialized range in vertical bone installation and precision measure process, concrete accuracy standard is as follows:
Build-up tolerance :≤± 1.0mm
Vertical bone web and base plate squareness :≤1.5mm (shown in Figure 1)
Vertical bone edge line degree :≤± 1.5mm
Require the same specification of vertical bone in the same segmentation, identical material.Vertical bone must be whole, and joint is not established in the centre.The different otch of floor otch katal passes through for vertical bone, and incision size should be determined according to the vertical bone shelves number that passes.
The form of cut or cuts of floor as shown in Figure 4, incision size c then determines according to the vertical bone shelves number that passes:
Vertical bone shelves number≤3 vertical bone web thickness+4mm of c=, about each 2mm (can make an explanation to the meaning of this parameter and a scope that can change up and down is provided?)
3＜vertical bone shelves number≤7 vertical bone web thickness+6mm of c=, about each 3mm
Vertical bone shelves number＞7 vertical bone web thickness+7mm of c=, about each 3.5mm
And the relation of each parameter shown in the figure is as shown in table 1:
Table 1 (unit: mm)
When 4, checking the floor cutting accuracy, specific requirement is as follows:
Oad cutting accuracy (length) :≤± 3.0mm
Oad cutting accuracy (highly) :≤± 2.0mm
Two ends otch spacing :≤± 3.0mm (shown in Figure 2)
5, floor end opening channel-section steel is installed.By test as can be known, when floor passes through many grades of vertical bones (more than 7 grades time),, can produce very big distortion because floor length direction rigidity is too little, thereby, must the end opening of floor fixedly channel-section steel with the rigidity of increase floor.Use chuck that channel-section steel is fixed.
6, floor being penetrated vertical bone is finished jointly by the tractive of a driving and three winchs.For drawing in of follow-up floor, the winch cable wire passes successively from the otch of front floor.Floor is in penetrating vertical bone process, if blocked by vertical bone web, the place of then floor can being collided prescinds about 2mm.
7, determine that welding process welds.
After floor was in place, welding process was determined (with reference to figure 3) according to assemblage gap, specifically:
Gap g≤4mm does not change the leg size
4mm＜gap g≤7mm leg size increases 2mm
7mm＜gap g≤12mm opens 30 ° of grooves of single face, adds ceramic substrate 1.
Gap g＞12mm adds benefit plate 2 and mounts, and with dash area 3 excisions.
