Description

Technical Field

[0001] This utility model relates to the technical field of building construction, specifically to a verticality adjustment component and adjustment device for steel structure columns during installation. Background Technology

[0002] In steel structure construction, steel columns, as core load-bearing components, directly affect the stability, safety, and subsequent construction accuracy of the overall structure. Excessive verticality deviation can lead to uneven load distribution, stress concentration at joints, and even structural deformation or collapse. Therefore, efficient and precise verticality adjustment devices have become a key technical requirement in steel structure construction. Traditional adjustment methods mainly rely on manual operation, such as using wedge shims, hand-operated hoists with inclined steel wires as guy ropes, or bolt fine-tuning devices for correction. However, these methods have significant drawbacks. First, the operation requires repeated measurement, adjustment, and verification, which is inefficient and susceptible to human error. Traditional methods cannot meet the stringent requirements of modern steel structure engineering (such as super high-rise buildings and large-span stadiums) regarding installation errors (typically ≤1 / 1000 column height and ≤15mm) in terms of adjustment accuracy, efficiency, and safety. Second, there are significant safety hazards when adjusting heavy components. Therefore, it is necessary to develop a verticality adjustment device for steel column installation to achieve integrated operation of "precise alignment, dynamic adjustment, and stable locking" for steel column installation.

[0027] like Figures 1-3 As shown, preferably, the lifting end of the jack 1 is fixed with an abutment plate 13, which is arranged perpendicular to the lifting direction of the jack 1. By fixing the abutment plate to the lifting end of the jack, it is convenient to adapt and abut against the lower surface of the steel column clamp.

[0028] like Figures 1-3 As shown, specifically, the abutment plate 13 is a long strip-shaped structure, and the lifting end of the jack 1 is vertically and fixedly connected to the middle position of the abutment plate 13.

[0039] In this embodiment, the connecting steel plate 21 is a rectangular ring structure. A connecting hole is provided at each corner of the connecting steel plate 21, and at least one connecting hole is provided on each side of the connecting steel plate 21, so that the fit between it and the pre-embedded bolt 51 is more stable and reliable.

[0040] The verticality adjustment device in this embodiment avoids the traditional methods of using diagonal steel wire ropes and fixed anchor points, greatly improving installation efficiency, reducing process steps, and ensuring accuracy in preventing errors caused by metal springback during the later stages of steel structure column tensioning. This device solves the problem of limited workspace and reduces the time required for steel column installation and alignment, thus guaranteeing the precision of steel structure column installation.

It employs the verticality adjustment device described in Embodiment 4 and includes the following steps: loosening the adjusting nut 52 and the control elevation nut 53; calibrating the verticality of the steel structure column 2 using a theodolite; then adjusting the verticality and elevation of the steel structure column 2 using multiple jacks 1 to ensure they meet the set requirements; and finally, fixing the steel structure column by tightening the adjusting nut 52 and the control elevation nut 53.

[0042] Specifically, the verticality adjustment method in this embodiment is used during verticality calibration after the initial installation of the steel structure column. The column is fixed to the steel structure column using steel column clamps and a protective rubber layer, and then secured with bolt assemblies. Jack bases and jacks are installed on all four sides of the steel structure column. The jack bases are placed on pre-embedded bolts, and the jacks are positioned on the bases, with their upper ends contacting the steel column clamps to bear force. Finally, two theodolites are used externally to calibrate the verticality of the steel structure column. Adjustments are made by loosening the adjusting nuts and control elevation nuts. Then, the verticality and elevation of the steel structure column are adjusted using the jacks on all four sides. After the verticality and elevation are adjusted, the steel structure column is fixed by tightening the adjusting nuts and control elevation nuts, thereby ensuring the installation quality of the steel structure column and achieving an integrated operation of "precise alignment - dynamic adjustment - stable locking" for the steel structure column installation.

[0043] The verticality adjustment method in this embodiment significantly improves adjustment accuracy and efficiency; enhances construction safety and stability; shortens installation time; and improves project quality and economy.
