Abstract
The invention discloses a method for controlling the welding deformation of a trapezoid-like cross section hollow sheet steel column, wherein an erection plate is firstly subjected to spot welding positioning with upper webs respectively and then subjected to discontinuous welding with webs when the position of the erection plate is accurately adjusted; then lower webs and the upper webs are laminated, the lower webs are welded with the erection plate; the steel column is overturned, a stiffening plate vertical to a wing plate is firstly combined with the wing plate and then welded with a stiffening plate in the direction vertical to the cross section of the column, afterwards, the wing plate is subjected to spot welding positioning with the upper webs and the lower webs; steel pipes are finally spliced and subjected to spot welding positioning with the two upper webs and the lower webs; and the wing plate is welded with the upper webs and the lower webs and the steel pipes are welded with the webs. Through the method provided by the invention, the construction process of the trapezoid-like cross section hollow sheet steel column is regulated while the welding length of the erection plate and the webs are reduced, thereby welding stress and deformation are effectively reduced and the processing formation of the trapezoid-like cross section hollow sheet steel column is guaranteed.
Description
Technical field
The present invention relates to class trapezoid cross section steel plate steel column welding procedure on an empty stomach.
Background technology
Class trapezoid cross section broad plate steel column on an empty stomach is big owing to the cross section, and thickness of slab is little, therefore, as easy as rolling off a log generation welding deformation in the process of welding production, the percent defective height is difficult to reach the requirement of standard.With Wukesong Indoor Stadium, Beijing is example, and its curtain wall steel support system has adopted class trapezoid cross section thin plate steel column on an empty stomach, and the steel column cross section is similar to isosceles trapezoid, according to former design, web and frame found the steel plate full weld, have manufactured experimently 4 Pin steel columns, far super design of welding deformation and code requirement all are waste product.The distortion of web plane both direction is mostly at 20～70mm, and welding stress discharges back up 150mm, and irregular.For reducing and eliminating welding deformation, once with web A, B bending after wing plate C blanking, in the hope of dealing with problems, but the bad control of bending angle, the wing plate distortion does not meet design requirement, and the welding deformation of web is not effectively controlled yet.Adopt symmetrical layering to weld the 1st step skip welding, weld length 50mm, spacing 150mm, the twice weld seam of symmetry welds simultaneously; The 2nd step was divided 3 welding with the skip welding spacing, and then last time, weld seam welded 50mm at every turn, until finishing.Welding deformation between wing plate, steel pipe and the web obtains bigger improvement, but the welding deformation of the upright steel plate of web and frame is not still controlled.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of class trapezoid cross section steel plate steel column welding procedure on an empty stomach, in the weld length that reduces upright steel plate of frame and web, reduce welding stress and distortion effectively, guaranteed the machine-shaping of broad plate steel column on an empty stomach of class trapezoid cross section.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: the class trapezoid cross section is thin plate steel column welding deformation controlling method on an empty stomach, it is characterized in that comprising the steps:
(1) make smooth processing platform, epiplastron, bottom web, wing plate, frame riser, the used steel plate of stiffener are pressed the blanking of figure paper size, spreading, smooth;
(2) the frame riser position line is drawn in epiplastron leveling, and first riser, second riser, the 3rd riser are located with epiplastron spot welding respectively, adjusts position accurately back and the welding of web interruption;
(3) the frame riser position line is drawn in bottom web leveling, closes sheet with epiplastron, bottom web and first riser, second riser, the 3rd riser welding;
(4) steel column is stood up, be placed on the shelf, upside down little, on wing plate, epiplastron, bottom web, draw the printed line of putting more energy into, earlier will be perpendicular to the stiffener of wing plate and wing plate combination, the stiffener of welding and column section vertical direction is located wing plate and epiplastron and bottom web spot welding then again;
(5) assembly unit steel pipe, steel column is stood up in steel pipe cutting, butt joint, straightening, make head-up little, steel pipe and two epiplastrons, bottom web spot welding location;
(6) wing plate and epiplastron, bottom web, steel pipe and web welding;
(7) smooth and crooked defective position flame correction, weld grinding is smooth, beats installing hole, is welded to connect otic placode;
(8) make a platform for lining, each segmented column of a steel column is carried out pre-assembly unit, promptly install by this numbering at numbering, scene;
(9) steel column impeller blasting reaches paint after the derusting grade, checks and accepts, and warehouse-in is waited to send out.
Preferably, described riser and epiplastron adopt and are interrupted the penetration welding.
Preferably, behind stroke frame riser position line, on the frame riser position line, beat the 12mm circular hole, bottom web and first riser, second riser, the 3rd riser plug welding welding.
Preferably, described wing plate and epiplastron, bottom web, steel pipe and web adopt penetration weld, the simultaneously symmetrical layering welding in both sides.
The present invention adjusts the construction technology of the broad slab of class trapezoid cross section empty stomach in the weld length that reduces frame riser and web, has reduced welding stress and distortion effectively, has guaranteed the machine-shaping of broad plate steel column on an empty stomach of class trapezoid cross section.
