Plate, when two revolving support components are equipped at outside of the group to frame 1, outside the wing plate of spill side plate and welded H section steel
Side is bonded, and the connecting plate on spill side plate is oppositely arranged, and is had and is pre-tightened clearance D, then carries out preload effect by preload piece 24,
So that revolving support component 2 is fixedly connected with frame 1 with group.
Wherein, the preload piece is preferably bolt and nut.
Large-size stainless steel welded H section steel group pair provided by the invention and revolution welder, can be realized H profile steel web and
Wing plate is precisely aligned and is rigidly fixed, and the revolution that can be realized weld seam two sides is alternately welded, and welding deformation is prevented.
The present invention also provides a kind of welding methods of large-size stainless steel welded H section steel, it is preferred to use above-mentioned welder,
As shown in figure 1-9, it the described method comprises the following steps:
Step 1, then installation, adjustment group place it in horizontal position to frame 1.
In the present invention, it measures first and ensures the top surfaces of multiple positioning plates 111 in same level, side is coplanar
And it is parallel with the side of framework 11 is adjusted.Then framework 11 will be adjusted to be placed in two horizontal pad piers, then by multiple locking clamping blocks
12 are fixed in adjusting framework 1 by rotary shaft 13, are organized in groups to frame.
Step 2, the web 100 of H profile steel to be welded and wing plate 200 are placed in and are adjusted in framework 11, make a wherein side wing
Precisely group pair is carried out with web, then fixes the position of the side wing.
Wherein, two blocks of wing plates are individually positioned in the two of positioning plate by the top surface that web is first lain in a horizontal plane in positioning plate 111
Side；Then using the height of web as standard, wing plate height adjusting part 115 is adjusted, so that the welding groove of wing plate and web is located at
Sustained height realizes precisely group pair；Wing plate fixing piece 116 is pre-tightened again, so that being adjacent on the inside of wing plate with the side of positioning plate, wing plate
Position fix.
Step 3, the welded gaps of web with the wing plate fixed are adjusted, then by the fixed web of locking clamping block 12, then
Another side wing is fixed on to adjust in framework 11.
In the present invention, after the welding groove position of wing plate and web is fixed, welded gaps are adjusted to predetermined value；Then
Pass through the position of the fixed web of locking clamping block, wherein so that the fast pulley 122 of locking clamping block is connected to the upper surface of web 100, and
Locking member 124 is pre-tightened, so that locking clamping block 12 is fixedly connected with framework 11 is adjusted.
The inventors discovered that web 100 is fixed position under the collective effect of positioning plate and locking clamping block, side and positioning
