Description
Technical field：
The invention belongs to steel construction system peace technical field, it is related to one kind to be carried out using general model
The method that datum line draws on the outside of H profile steel component flange plate.
Background technology：
Datum line is mainly used for carrying out flange plate side attached on the outside of the flange plate of H profile steel steel member
The installation of the group weldering positioning and integrated member of part is checked and (can just accomplish precision based on unified benchmark
Ensure), consider that it should overlap with web thickness center line for design stress.Generally draw
The method of the datum line by part Steel Ruler 3 in diverse location as shown in figure 1, measure the edge of a wing
The widthwise central point 4 of plate 5, the widthwise central point 4 for then connecting diverse location forms datum line
5, or directly using drawing, in the web group on flange plate 5, to position line, (2 groups of web is welded in the wing
Position line on listrium 5) regard datum line.
Above method draws on the outside of flange plate datum line because it exists so that flange plate is positioned in itself
Following shortcoming：
1st, datum line draw influence factor it is many (flange plate cutting stock precision, assembling precision,
Welding deformation etc.), quality should not ensure (it is difficult to ensure that in flange plate datum line and web thickness
Heart line overlaps)；
2nd, the precision because being largely determined by flange plate in itself and its with web group pair, therefore under
The process quality requirement of material, group pair and welding is relatively tight, so as to cause cost increase, claim for eot；
3rd, difficulty is modified to the datum line deviation caused by factors above big, can be caused into
This increase, efficiency reduction.
The content of the invention：
It is an object of the invention to provide the datum line side of drawing on the outside of a kind of H profile steel component flange plate
Method, the method is simple to operate, efficient, because can directly ensure to draw as positioning datum with web
Datum line and web thickness center line overlap on the outside of the flange plate of system, draw Mass accuracy it is high,
Influence and restraining factors are few, low to operation deviation and deformation requirements, and amendment is convenient, so that greatly
It is big to improve efficiency and reduce construction cost.
As above conceive, the technical scheme is that：A kind of outer side base of H profile steel component flange plate
Directrix draws method, it is characterised in that：Comprise the following steps：
1. general model is made：The model includes featuring working panel, the framework of scale label
Outer floor, framework inner rib plate, multiple stiffeners and web contact base plate；The outer floor of the framework
With framework inner rib plate along working panel inside and outside periphery bending group weld, the multiple stiffener with
Formed after working panel vertical welding as the stable ∏ types framework of general model main body；It is described steady
Determine the affixed web contact base plate in a side end face of ∏ type frameworks, being formed with scale in other end side carves
Degree；
2. general model is placed and looked for a little：General model is connected across H profile steel component flange plate not
Same position, web contact base plate will steadily be contacted with web surface during placement, it is ensured that working panel
Vertical with web surface, framework inner rib plate is close near the side of scale label and with flange plate；
3. datum mark draws and line：General model is connected across H profile steel component flange plate not
After with position, web half thickness value is read on scale label, benchmark is marked in this position
Point, then forms part datum line by the datum mark line of diverse location；
4. amendment is checked：Using general model base is checked in annex group pair or other centre positions
The accuracy of directrix, if any error, after the drawing of amendment datum mark is checked in encryption, connects each base
On schedule and check amendment datum mark datum mark and formed and check revised datum line.
The bottom surface that 0 position of said scale scale should contact bottom with web is alignd, web contact
Base plate and working panel keep vertical.
Aforementioned stable ∏ type frameworks both sides are respectively welded a handle.
The present invention efficiently realizes that the high accuracy of flange plate side base directrix is drawn by a general model
Line draws, and completes web thickness center to the accurate transmission of flange plate side.One limb when model is placed
Web is contacted with, and is steadily contacted with web surface by web contact base plate, it is ensured that working face
Plate is vertical with web surface, so as to reduce error, the framework inner rib plate of model is near scale label
Side and be close to flange plate, the point corresponding to web half thickness value is marked by scale label
Part datum line is formed between as datum mark, point after line, then can use other positions point to be answered
Core amendment.
The present invention is a kind of high accuracy, convenient, the efficient flange plate outside positioned with web
Datum line draws method.The method is simple to operate, efficient, because can by positioning datum of web
Overlapped with datum line on the outside of the direct flange plate for ensureing and drawing and web thickness center line, drawn
Mass accuracy is high, influence and restraining factors are few, low to operation deviation and deformation requirements, amendment
It is convenient, so as to substantially increase efficiency and reduce construction cost.

Specific embodiment：
Datum line draws method on the outside of a kind of H profile steel component flange plate, comprises the following steps：
1st, as shown in Figure 3,4：Make general model：The model includes featuring scale label
9 working panel 12, multiple stiffeners 13, the outer floor 11 of framework inner rib plate 14, framework
With web contact base plate 7.The outer floor of the framework and framework inner rib plate along working panel,
Bending group in neighboring is welded, and is formed as logical after the multiple stiffener and working panel vertical welding
With the stable ∏ types framework of model main body；The affixed web in one side end face of the stabilization ∏ type frameworks
Contact base plate, scale label is formed with other end side.
General model is made, model will ensure working panel 12 in a plane, and web connects
Bottom out plate 7 and keep vertical with working panel 12,0 position of scale label 9 contacts with web
The bottom surface of base plate 7 flushes.
2nd, model is placed and looked for a little：
As shown in Figure 2：General model 8 is connected across the diverse location of H profile steel component flange plate
(placement location sets with required precision, and required precision is high, takes that a position is near, quantity is more；Together
When end nearby and flange plate side has the position that annex group is welded to try one's best setting), during placement such as Fig. 5
Shown web contact base plate 7 will steadily be contacted with web surface 1, it is ensured that working panel 12 with
Web surface 1 is vertical.Framework inner rib plate 14 is tight with flange plate 6 near the side of scale label 9
Patch.
3rd, datum mark draws and line：
As shown in Figure 5：Model reads web after diverse location placement on scale label 9
Half thickness value, datum mark 4 is marked in this position.For example：Fig. 5 web thickness is 20mm,
Then the dot-dash datum mark 4 at the 10mm scales of scale label 9, then as shown in Figure 2 will not
The flange plate datum line 5 for drawing is formed with the line of datum mark 4 of position.
4th, amendment is checked：
As shown in Figure 6：Using general model benchmark is checked in annex group pair or other centre positions
The accuracy of line, if any error, after the drawing of amendment datum mark 15 is checked in encryption, connection is each
Datum mark 4 checks revised datum line 16 with the datum mark formation of amendment datum mark 15 is checked.
