Accompanying drawing explanation
Fig. 1 is the assembly welding method of the present invention, adjusts schematic diagram during circular gap；
Fig. 2 is the assembly welding method of the present invention, adjusts schematic diagram during radial clearance；
In figure, reference is: wallboard 1, fixture 2, voussoir 3, hangers 4.
Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings: as shown in Figure 1:
Stave sheets assembly welding method, including longitudinal joint assembly welding step and circumferential weld assembly welding step, longitudinal joint assembly welding step includes that order is carried out
Following steps:
A, on two pieces of adjacent wallboards, it is respectively welded hangers 4, welds at least one fixture 2, fixture 2 in the longitudinal joint position of wallboard
Welding method is: Clamp for welding 2 on adjacent one piece of wallboard in two pieces of wallboards, described fixture 2 is L-shaped, L-shaped one end and wall
Plate welds, and the L-shaped other end exceeds edge, wallboard longitudinal joint place predeterminable range；
B, connect with the hangers 4 of adjacent wallboard respectively with chain block two ends, tighten up chain block, make two pieces of wallboards close to each other
To needs position, knocking in voussoir 3 in the gap of fixture 2L shape end, make voussoir 3 side push against fixture 2, opposite side promotes
Wallboard is radially moved into needs position；Spot welding fixation wall Board position, completes longitudinal seam welding；
Circumferential weld assembly welding step includes the following steps that carry out of order:
C, the circumferential weld position of wallboard weld described fixture 2, fixture 2 welding method is: a piece in two pieces of adjacent wallboards
Clamp for welding 2 on wallboard, fixture 2L shape one end welds with wallboard, and the L-shaped other end exceeds edge, wallboard circumferential weld place predeterminable range；
D, the wallboard on circumferential weld top of slinging with suspender, control upper and lower two pieces of wallboards 1 close to each other to needs position, to fixture 2L
Knocking in voussoir 3 in the gap of shape end, make voussoir 3 side push against fixture 2, opposite side promotes wallboard to be radially moved into needs
Position；After spot welding fixation wall Board position, complete girth welding.
As shown in Figure 1, 2, this assembly welding method, first at wallboard 1 appropriate location welding hangers 4 and fixture 2, utilize chain block
Adjust the circular gap of two pieces of wallboards 1, in the tip-clearance of fixture 2, knock in voussoir 3 adjust the radial clearance of two pieces of wallboards 1,
Can weld subsequently.
Concrete, for longitudinal joint assembly welding, operation order is it may be that as it is shown in figure 1, be respectively welded on two pieces of adjacent wallboards
Hangers 4, is used for connecting chain block, tightens up calabash, makes two pieces of wallboards 1 close, is i.e. to adjust wallboard circular gap.
At the longitudinal joint position Clamp for welding 2 of wallboard, as in figure 2 it is shown, fixture 2 welding method is: adjacent in two pieces of wallboards one
Clamp for welding 2 on block wallboard, described fixture 2 is L-shaped, and L-shaped one end is welded with wallboard, and the L-shaped other end exceeds wallboard longitudinal joint institute
At edge predeterminable range, knocking in voussoir 3 in the end of L-type, allow voussoir 3 side push against fixture 2, opposite side promotes and does not connect
That block wallboard 1 connecing fixture 2 moves radially, and is i.e. to adjust wallboard radial clearance.
Size according to wallboard 1 is different, can be to arrange a fixture 2 at wallboard 1 medium position, it is also possible to be on wallboard
Lower end is respectively provided with fixture 2, adjusts the radial clearance of two some positions of upper and lower side respectively, in like manner can also arrange more fixture 2.
Pulling chain block to adjust circular gap, after adjusting radial clearance with voussoir 3, spot welding is fixed, and then completes longitudinal joint
Welding.
Circumferential weld assembly welding method principle is essentially identical, the circumferential weld position of wallboard weld described fixture 2, with suspender such as drive a vehicle, calabash
Deng device, the wallboard on circumferential weld top of slinging, control upper and lower two pieces of wallboards 1 close to each other to needs position, to fixture 2L shape end
Gap knock in voussoir 3, voussoir 3 promotes wallboard to be radially moved into needs position, spot welding to fix, and then completes circular seam welding
Connect.
According to assembly welding flow process or the difference of welding position, can be first to weld girth welding after longitudinal joint, it is also possible to weld after first girth welding
Longitudinal joint.
Shape according to wallboard is different, during girth welding, can be to weld one or more fixtures 2 in circumferential weld position, it is simple to adjust
The radial position of multiple some positions.
Such as it may be that first carry out longitudinal joint assembly welding, then carrying out circumferential weld assembly welding, described step B obtains monoblock after completing longitudinal seam welding
Annular wall plate, in described step C, welds two described fixtures 2, the welding position of two fixtures 2 in the circumferential weld position of wallboard
Perpendicular to one another with the annular wall plate center position line of assembly welding.
It is i.e. the longitudinal joint assembly welding first completing a circle wallboard, obtains the wallboard of monoblock annular, wallboard two fixtures 2 of welding of annular, two
Fixture 2 center position line is perpendicular to one another, by two fixtures 2 can planar before and after adjust respectively with left and right directions,
After position determines, spot welding is fixed, then completes girth welding.
