Specific embodiment
The embodiment of the present invention will be described in further detail below.
Special-shaped Multicarity colossal column welding deformation controlling method of the invention, its preferably specific embodiment is：
Including step：
A, welding matrix pattern component outer wall horizontal position welding seam amount to 4；
4 cross joints in B, the huge post cavity of welding；
C, huge 4 cross joints of pole panel of welding；
D, welding inner chamber matrix pattern component connect 8 horizontal position welding seams；
E, 4 horizontal position welding seams of welding i-shape component；
F, the huge post of welding vertically divide 6 horizontal position welding of cavity plate to stitch；
G, huge 4 downhand welds of post sash plate of welding.
Before step A is carried out, first to 4 cross joints of 4 cross joints and the huge pole panel in the huge post cavity
Make tack welding.
Special-shaped Multicarity colossal column welding deformation controlling method of the invention, by optimizing welding process, changes site welding
Order is connect, welding deformation is reduced.
Specific embodiment：
Welding sequence is one of principal element of influence welding structure deformation, and the principle for arranging welding sequence is：1) try one's best
Using being symmetrically welded.2) asymmetric structure is arranged to some weld seams, should the few side of first welding line.3) first weldering amount of contraction is big
Weld seam, weldering amount of contraction is small afterwards obtains weld seam.The method that generally " horizontal after first standing " is taken in welding, i.e., weld cross joint, Zhi Houzai first
Welding horizontal position welding seam.Following welding sequence is taken after considering：
As shown in Figures 1 to 7：
Step one：Weld 4 cross joints in huge post cavity.
Step 2：Weld 4 cross joints of huge pole panel.
Step 3：Welding matrix pattern component outer wall horizontal position welding seam amounts to 4.(tack welding is done to eight cross joints before another weldering)
Step 4：Welding inner chamber matrix pattern component connects 8 horizontal position welding seams.
Step 5：4 horizontal position welding seams of welding i-shape component.
Step 6：Weld huge post vertically 6 horizontal position welding seams of point cavity plate.
Step 7：Weld huge 4 downhand welds of post sash plate.
As shown in figure 8, being learnt by field test：After eight vertical welding seam welding are finished, due to vertical weld contraction, make
Obtain two matrix pattern casings and inwardly extrude I-shaped casing, influence the installation of component in place, by optimizing welding sequence, by eight
After cross joint spot welding positioning, the peripheral horizontal position welding seam of preferential two matrix pattern cavitys completes vertical weld seam again afterwards, is sent out through overtesting
Now can be very good to solve problems, the welding sequence after improvement is as follows：
As shown in Fig. 9 to Figure 15：
Step one：Welding matrix pattern component outer wall horizontal position welding seam amounts to 4, and tack welding is made to eight cross joints before weldering.
Step 2：Weld 4 cross joints in huge post cavity.
Step 3：Weld 4 cross joints of huge pole panel.
Step 4：Welding inner chamber matrix pattern component connects 8 horizontal position welding seams.
Step 5：4 horizontal position welding seams of welding i-shape component.
Step 6：Weld huge post vertically 6 horizontal position welding seams of point cavity plate.
Step 7：Weld huge 4 downhand welds of post sash plate.
The optimization that the present invention passes through welding sequence, deforms excessive problem after solving matrix pattern cavity welding, improve
Housing cylinder Steel Structure Installation efficiency.The postwelding correction problem that engineering welding deformation causes is solved, construction efficiency is improve, and
It is safe and reliable.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any one skilled in the art in the technical scope of present disclosure, the change or replacement that can be readily occurred in,
Should all be included within the scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims
Enclose and be defined.
