Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel column misalignment reinforcement technology in building engineering, and in particular to an auxiliary device for steel column misalignment reinforcement. Background Technology
[0002] In steel structure construction, misalignment of steel columns can lead to uneven stress distribution and affect overall stability. Traditional methods typically focus on correction, but once a steel column is misaligned after construction, correction is no longer possible, and if the misalignment exceeds the allowable value specified in the code, steel plates need to be used to reinforce the inside of the misaligned edge of the column to improve its load-bearing capacity. However, using steel plates of inappropriate thickness often results in the following consequences: (1) Insufficient load-bearing capacity: If the steel plate thickness is insufficient, it may not effectively improve the load-bearing capacity of the steel column, causing the column to deform or break under stress. This will reduce the overall stability and safety of the structure, and may even lead to structural collapse.
[0003] (2) Welding quality issues: Excessive steel plate thickness may increase welding difficulty, leading to incomplete welding or defects such as incomplete penetration, porosity, and slag inclusions. These welding defects can affect the strength and durability of the weld, reducing its reinforcing effect.
[0004] (3) Uneven stress distribution in the structure: Inappropriate steel plate thickness may lead to uneven stress on the reinforced steel columns, further affecting the stability of the structure. This can cause localized stress concentration and accelerate fatigue damage to the structure.
[0005] How to solve the above problems is the research topic of this plan. Utility Model Content
[0006] In order to achieve the above-mentioned objectives and address the above-mentioned technical problems, this utility model provides an auxiliary device for reinforcing misaligned steel columns.
[0007] The technical solution includes two mating U-shaped plates set at the misalignment of the upper and lower steel columns and a threaded rod set on the U-shaped plates. The threaded rod is set through the U-shaped plates, and a top plate assembly is set at one end of the threaded rod located in the inner area of the two U-shaped plates. The top plate assembly contacts the side wall of the steel column. The top plate assembly includes a single-layer top plate corresponding to the side wall of a single steel column and upper and lower top plates corresponding to the side walls of two upper and lower steel columns. The threaded rod is provided with a scale, and the threaded rod is fixed to the C-shaped plate by a nut.
[0008] The U-shaped plate includes a main board and side plates disposed at both ends of the main board; Each of the two side panels has a connecting lug on one side; The two U-shaped plates are fixedly connected by bolts.
[0009] Both the motherboard and the side panel are provided with two rows of through holes, one above the other. The threaded rod slides into the through hole.
[0010] The threaded rods located on the two side plates of the U-shaped plate have a single-layer top plate on one side and upper and lower top plates on the other side. The threaded rods located on the two main plates of the U-shaped plate have a single-layer top plate on one side and upper and lower top plates on the other side.
[0011] The beneficial effects of the technical solution provided by this utility model embodiment are: (1) The degree of misalignment between the upper and lower steel columns can be accurately measured by the scale on the threaded rod, thereby determining the required thickness of the steel plate. This ensures that the thickness of the reinforcing steel plate is appropriate and can effectively improve the load-bearing capacity of the steel column.
[0012] (2) By adjusting the nut and threaded rod, it can adapt to steel columns with different degrees of misalignment, and has strong adaptability. This makes the device suitable for a variety of misalignment situations, including slight and severe misalignment.

[0024] Example 1 See Figures 1 to 4 This utility model provides an auxiliary device for reinforcing misaligned steel columns, including two U-shaped plates 1 that are connected together at the misalignment of upper and lower steel columns and a threaded rod 2 that is set on the U-shaped plates 1. The threaded rod 2 is set through the U-shaped plates 1. A top plate assembly is set at one end of the threaded rod 2 located in the inner area of the two U-shaped plates 1. The top plate assembly contacts the side wall of the steel column. The top plate assembly includes a single-layer top plate 301 corresponding to the side wall of a single steel column and upper and lower top plates 302 corresponding to the side walls of the upper and lower steel columns. The threaded rod 2 is provided with a scale, and the threaded rod 2 is fixed to the U-shaped plate 1 by the nut 5.
[0025] The U-shaped board 1 includes a main board and side plates disposed at both ends of the main board; Each of the two side plates is provided with a connecting ear plate 101 on one side; The two U-shaped plates 1 are fixedly connected by bolts 4.
[0026] Both the motherboard and the side panel have two rows of through holes, one at the top and one at the bottom. The threaded rod 2 slides and matches the through hole.
[0027] The threaded rod 2 located on the two side plates of the U-shaped plate 1 has a single-layer top plate 301 on one side and an upper and lower top plate 302 on the other side. The threaded rod 2 located on the two main plates of the U-shaped plate 1 has a single-layer top plate 301 on one side and an upper and lower top plate 302 on the other side.
[0028] When steel columns are misaligned, reinforcement measures are required. This is achieved by adding steel plates at the misalignment points between upper and lower steel columns to improve the load-bearing capacity and stability of the columns, thus resolving the misalignment problem. Specific methods are as follows: First, the required thickness of the steel plate is confirmed by the device. The two U-shaped plates 1 are installed together at the misalignment of the upper and lower steel columns, and the connecting ear plates 101 are fixedly connected by bolts 4. The single-layer top plate 301 at the end of the threaded rod 2 at the upper row of through holes corresponds to the upper steel column, and the single-layer top plate 301 at the end of the threaded rod 2 at the lower row of through holes corresponds to the lower steel column. The top plate assembly is pressed against the side wall of the steel column in front and back and left and right correspondences and is fixed by nuts. The difference is calculated by recording the scale on the upper and lower threaded rods 2, so as to obtain the required thickness of the steel plate. Note: The side walls corresponding to the upper and lower top plates 302 are the side walls between the upper and lower steel columns without misalignment; Then, the butt weld is planed down to the substrate, and the paint in the welding area is removed; A steel plate with a cross-sectional width 50mm less than the original column is used on the inner side of the misaligned steel column. A plug hole with a diameter of 22 is pre-drilled in the middle of the steel plate, with a horizontal and vertical distance of 90mm. The steel plate is 400mm long and the plate width is equal to the cross-sectional width minus 50mm. Nine plug holes are used to ensure that the reinforcing steel plate fits tightly with the column. An 8mm welding gap is left in the area of the butt weld with the column. The steel plate is welded using a three-sided surround welding method, and then the butt weld is performed. After welding is completed, the weld seam is cleaned and trimmed to ensure that the surface of the welded joint is flat and smooth; The dimensions and shape of the weld seam are inspected at the diagonal, and non-destructive testing of the weld seam is performed to ensure that the size and shape of the welded joint meet the design requirements.
[0029] When a completed steel column is misaligned and cannot be corrected, and the misalignment deviation exceeds the allowable value specified in the code, this reinforcement method can significantly improve the load-bearing capacity of the steel column. It eliminates the need to replace the steel column, saving materials and construction costs. It is applicable to various misalignment situations, including minor and severe misalignments.
[0030] Example 2 Based on Embodiment 1, a flat surface is provided on the top of the threaded rod 2, and a scale is provided on the flat surface.
[0031] The required thickness of the steel plate can be obtained from the scale.
