By adopting the steel pipe column alignment method, the step A is to process the steel pipe column alignment structure, the step B is to adjust the relative position of the positioning plate 3 and the corresponding positioning clamp by adjusting the steel pipe column 4 above, the step C directly descends the steel pipe column 4 above to a specified position to complete alignment, because the two clamping arms of the positioning clamp plate 1 have a guiding effect on the positioning plate 3, and meanwhile, the two clamping arms of the positioning clamp plate 1 can limit the positioning plate 3, so that the efficiency of the steel pipe column 4 below the upper steel pipe column 4 in alignment can be improved. The steel pipe column alignment method is simple to operate and convenient to construct, the alignment efficiency of the two steel pipe columns 4 which are adjacent up and down can be improved, and the construction time for butt joint of the steel pipe columns 4 is greatly shortened.
Specifically, the present example will be described by taking the steel pipe column positioning structure described in example 1 as an example. The steel pipe column alignment method comprises the following construction steps:
firstly, assembling the positioning clamp: clamping the connecting sections 12 of the two clamping plates 1 at two sides of the supporting plate 7 and connecting the two clamping plates through the connecting bolts 8, wherein the width of the gap 13 between the two clamping plates 1 at one end close to the positioning plate 3 is larger than the width of the gap 13 at one end close to the supporting plate 7; the step of assembling the positioning fixture is to process the positioning fixture of the steel pipe column alignment structure, connect the two clamp plates 1 to both sides of the support plate 7 through the connecting bolts 8, and when connecting the two clamp plates 1, through the operation of incompletely screwing the connecting bolts 8, make the width of the gap 13 between the two clamp plates 1, which is used for being close to one end of the positioning plate 3, greater than the width of the gap 13, which is used for being close to one end of the support plate 7, the end of the gap 13, which is close to the positioning plate 3, is the inlet of the positioning plate 3, the inlet width of the gap 13 is greater, which is beneficial for the positioning plate 3 to enter the gap 13, and is convenient for the alignment construction of the upper steel pipe column 4 and the lower steel pipe column 4.
After all the positioning clamps are assembled, step a1 is performed: according to the design, all the positioning clamps and all the positioning plates 3 are respectively connected to the corresponding first interfaces and the corresponding second interfaces; connecting the vertical plates of all the first supporting brackets 21 and the vertical plates of all the second supporting brackets 22 to the inner wall or the outer wall of the corresponding steel pipe column 4 respectively according to design, enabling the transverse plates of the first supporting brackets 21 to extend out of the end face of the first connector, and enabling the transverse plates of the first supporting brackets 21 and the transverse plates of the second supporting brackets 22 to be arranged in a matched mode;
then, step C is carried out: and lowering the upper steel pipe column 4 to enable the positioning plate 3 to be positioned between the two corresponding clamping plates 1, enabling the positioning plate 3 to move towards the supporting plate 7 along the clamping plates 1 until the transverse plate of the first supporting bracket 21 abuts against the transverse plate of the second supporting bracket 22, and aligning the upper steel pipe column 4 with the lower steel pipe column 4. At this time, the transverse plate of the second support bracket 22 contacts the transverse plate of the first support bracket 21, and the first support bracket 21 can support the second support bracket 22, that is, the lower steel pipe column 4 temporarily supports the upper steel pipe column 4; and a gap for welding construction is formed between the lower end face of the upper steel pipe column 4 and the upper end face of the lower steel pipe column 4. After the alignment is completed, the bolts on the supporting plates 7 can be screwed in the corresponding steel pipe columns 4, and the clamping plates 1 and the positioning plates 3 are connected through the bolts, as shown in fig. 6, so as to form temporary supports, which facilitate the following welding operation.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
