End stone and set square, further comprising the steps of:
S1. according to the length of H-type rod piece, between determining between the quantity and each scribing line pedestal of required scribing line pedestal 1
Away from；
S2. the center line of H-type rod piece and its transverse center of two end webs, edge of a wing plate hole group are marked on scribing line pedestal
Line；
S3. according to the center line of H-type rod piece, the side stop location of flange plate is determined；
S4. the position of end stone is determined according to the cross central line of two end web holes of H-type rod piece group；
S5. H-type rod piece is lifted, its web is in a horizontal position, using horizontal adjustment cushion block by H-type rod piece integrated regulation
To horizontality；
S6. the flange plate of H-type rod piece and side block are adjacent to, then H-type rod length direction is adjusted, so that
The one end of H-type rod piece is closely attached on end stone；
S7. by edge of a wing plate hole group line-transect leads to the flange plate at H-type rod piece both ends using set square, for the transverse direction of web
Center line is delineated by benchmark line of end stone contact surface on the web of H-type rod piece.
In the step S2, in scratching process, it need to guarantee both ends of the hole group's cross central line spacing and H-type rod piece center
The straightness of line.
In the step S3, the position of side block has several, the contact of each position upper lateral part block and H-type rod piece
Face should be in same plane.
In the step S4, when arranging the end stone of H-type rod piece one end, Ying Liuyou surplus, and end stone is answered
Perpendicular to side block.
The scribing line pedestal is scribing line cast steel platform.
There are six the horizontal adjustment cushion block is set, it is located at the both ends and middle position of H-type rod piece.
The width of the end stone is greater than the steel wing plate spacing of H-type rod piece.
In the above technical solution, a kind of scribble method suitable on overlength H-type rod piece provided by the present invention is gone back
With the following the utility model has the advantages that
1. operation intensity of the present invention is low, used tooling is bolted on scribing line pedestal, and it is convenient to dismantle；
2. the present invention is versatile, for same type rod piece, it is only necessary to whole rod piece scribing line once can be completed in positioning, for
Different type rod piece, it is only necessary to the end stone of one end is adjusted, and side block is without being adjusted；
3. present invention scribing line precision is high, it is only necessary to will can carry out scribing line operation after the tool locatings such as block, not need laser
Other scoring equipments such as level meter；
4. invention has the advantages of high efficiency, required operating personnel's quantity is few, it is only necessary to 1~2 operating personnel, it will be able to quick, high
Carry out scribing line operation to effect.
