Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel column installation technology, and in particular to a positioning and adjustment device for fixing steel pipe columns. Background Technology
[0002] Triangular steel columns are a type of building with strong bending resistance. They are characterized by arranging the material area further away from the axis of inertia, which can enhance the bending resistance of the components under the same axial resistance and save materials.
[0003] Currently, steel column assembly typically employs a vertical assembly method due to site limitations. This method involves sequentially assembling and welding the steel columns from bottom to top, meaning assembling from the bottom up. Since most sections require installation at height, ensuring the verticality of each section meets specifications is crucial. Traditionally, a retaining plate is welded to the outside of the steel pipe at the connection between upper and lower sections, followed by adjustment using jacks. However, this method is prone to safety hazards due to loose jacks during adjustment, and the retaining plate can easily damage the base material later. Adjustment is then performed on the upper section. Once in place, the flanges of the upper and lower sections are fastened together with high-strength bolts. At this time, the cladding plates between the sections have not yet been installed and fixed. However, the steel column is too tall, and the wind has a great impact on the top of the uppermost section of the column, which is very easy to cause swaying and poses a safety hazard. In order to ensure construction safety, the crane can only be released after the cladding plates are completely positioned and installed. However, the complete positioning and installation of the cladding plates is very time-consuming, resulting in low on-site installation efficiency. The traditional method requires welding plates onto the steel pipe. After installation, the plates need to be cut off. During the cutting process, the base material is easily damaged, and the surface cannot be cleaned properly.
[0004] Therefore, we propose a positioning and adjustment device for fixing steel pipe columns. Utility Model Content

[0030] The working principle of this utility model is as follows: During the assembly and manufacturing of the steel column in the factory, the positioning lines of the clamps are clearly marked; before the steel column segments are shipped, the clamps are first installed and fixed according to the previously marked positioning lines. The adjustable support assembly is then connected to the first connecting assembly 11 below the first column steel pipe 10 via a pin; the prepared second column steel pipe 22 is hoisted above the installed first column steel pipe 10 using a crane, and the adjusting screw 16 on the adjustable support assembly is rotated to adjust the overall length of the adjustable support assembly, connecting the adjustable support assembly to the second connecting assembly 21 on the second column steel pipe 22. By adjusting the length of each adjustable support assembly, the verticality of the first column steel pipe 10 reaches the design requirements. At this point, gaps will appear between the first column steel pipe 10 and the second column steel pipe 22; these gaps are then filled with prepared thin shims. High-strength bolts were used to secure the flanges of the first column steel pipe 10 and the second column steel pipe 22. The verticality of the first column steel pipe 10 and the second column steel pipe 22 was checked again. If it was not up to standard, it was readjusted. After the data was qualified, the crane was detached from the fixed first column steel pipe 10 to prepare for the hoisting of the next segment. Finally, the inter-segment sealing plate was positioned and installed using an automatic lifting platform.
