Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1 and 2, the inner insert plate type steel pipe column butt joint node provided by the present invention includes a lower steel column 1, an upper steel column 2, an inner insert plate 3, a lining plate 4 and a steel wedge 5; wherein, hypomere steel column 1 and upper segment steel column 2 are the steel-pipe column, during the construction, carry out hypomere steel column 1 hoist and mount as the hoist and mount otic placode through the interior picture peg earlier, carry out the hoist and mount of upper segment steel column 2 after finishing, in the interior picture peg 3 of hypomere steel column 1 inserts upper segment steel column 2 completely in the upper segment steel column 2 of upper segment steel column 2 hoist and mount position, set up steel wedge 5 in the lateral wall upper surface of hypomere steel column 1 this moment, the outside of steel-pipe column sets up a plurality of and evenly distributed. After the upper section steel column 2 is located, the butt joint of the steel columns is measured by using a welding seam detection ruler, whether the misalignment of the upper and lower steel pipe column pipe walls is within a standard allowable deviation (less than or equal to 3mm) is checked, uniform alignment is carried out, and the position with larger misalignment is corrected by using a steel wedge 5 until the standard requirement is met. The cable wind rope is simultaneously pulled in four directions of the steel column and is used for adjusting the verticality of the upper steel column 2 and ensuring the stability of the upper steel column, and after the verticality and the plane position of the upper steel column 2 are adjusted, the upper steel column can be tightly attached to the lower steel column 1 through the steel wedge 5.
As shown in fig. 1, after the installation of the upper-section steel column 2 is completed and the planar position of the upper-section steel column is accurate, the cable wind rope can be tensioned, the butt welding seam is subjected to tack welding in the groove, the thickness of the welding seam is not more than 3mm, the length of the welding seam is not less than 40 mm, and the distance between the welding seam and the groove is 300 mm-600 mm; and taking out the steel wedge 5 after the positioning welding is finished. The butt welding seam is symmetrically welded by two welders at the same time (as shown in figure 2), and in the welding process, because the metal filling amount of the welding seam is large, the welding shrinkage is large, interlayer tearing is easy to generate, multilayer multi-pass welding is adopted, and the swing width is not easy to be overlarge.
Welding sequence of butt welding seam: each steel column is welded simultaneously at equal speed by two welders at symmetrical positions. And starting welding at the position in the steel pipe column in the anticlockwise direction. After welding one layer, the second layer and the subsequent layers are welded at the position 30 mm-50 mm away from the welding starting point of the previous layer. The welding slag should be carefully checked every welding pass. The final layer of cover weld seam can be welded by adopting small current. In the welding process, the two layers of crosses are welded alternately once.
The interposer 3 plays a role of: (1) the lower steel column is used as a lifting lug plate when being installed; (2) a limiting device used when the upper end steel column is installed; (3) the rigidity of the lower steel column 1 is increased, and deformation generated in the welding and installation processes is prevented. The function of the lining plate 4 is: (1) limiting the upper section of steel column during installation; (2) the steel column side wall is prevented from being punctured during full penetration welding, and root penetration welding is guaranteed. The steel wedge 5 has the following functions: (1) ensuring the splicing gap of 5 mm; (2) prevent the occurrence of welding defects such as poor penetration of the root portion and slag inclusion.
The above embodiments are only used for illustrating the technical solutions of the present invention and are not limited thereto, and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of the technical solutions of the present invention.
