Description

Technical Field

[0001] This utility model relates to the field of steel structure building technology, and in particular to a device for adjusting the misalignment of steel beams. Background Technology

[0002] Steel beam misalignment refers to the cross-sectional displacement that occurs at the joint of two butt-jointed steel beams during the installation or manufacturing process of a steel structure. This manifests as the flanges or webs of the beams not being fully aligned, resulting in misalignment at the joint. This deviation can occur horizontally (left-right misalignment), vertically (up-down misalignment), or both. If the misalignment exceeds the allowable value specified in the code, it will affect the load-bearing performance of the welded joint of the steel beam, impacting its appearance and potentially causing it to fail acceptance testing.

[0003] A highly adaptable adjustable connector for steel structures is disclosed in Chinese patent document CN220117457U. This connector includes a first steel beam, a first connecting plate, a second steel beam, a first connector, and a second connector. The first connecting plate is hinged to the lower part of the second connecting plate via a hinge shaft. An inclined support beam is rotatably mounted on the outer side of the second adjusting block via a rotating shaft. The connecting shaft passes through and is inserted into the interior of the first connecting plate and the connecting cylinder. This invention, through the coordinated arrangement of a first adjusting bolt, a first adjusting block, a support beam, a second adjusting block, a second adjusting bolt, a fixing groove, a fastening bolt, and a fastening nut, allows the connector to be adjusted to fit the required angle between the steel beams. Through the coordinated arrangement of the connecting shaft, the connecting cylinder, and the limiting bolt, another direction of angle adjustment between the first and second steel beams is achieved, further improving the adaptability and flexibility of the connector. However, this highly adaptable adjustable connector for steel structures has a complex structure and poor practicality.

[0004] To address the shortcomings of the existing technology, providing a device for adjusting the misalignment of steel beams is a problem worthy of research. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of cross-sectional offset at the joint of the steel beam, which leads to misalignment at the joint. It provides a device for adjusting the misalignment of the steel beam, which achieves the technical effect of easy disassembly and good adjustment of the misalignment.

[0006] The objective of this utility model is achieved through the following technical solution: A device for adjusting the misalignment of a steel beam includes a straightening steel plate, a nut fixedly connected to one side of the straightening steel plate, a bolt threadedly connected to the nut, and a threaded steel bar fixedly connected to the end of the bolt. The device has a simple structure and adjusts the vertical displacement of the screw by rotating the threaded steel bar to drive the ordinary screw. This facilitates the adjustment of the misalignment of the steel beam to meet the allowable range of the acceptance specifications. The device is also easy to make using scrap materials, and is simple, convenient, and allows for quick adjustment.

[0007] Optionally, the correction steel plate is in the shape of a "7". By setting the correction steel plate to the shape of a "7", when correcting the misalignment of the steel beam, the inner right angle of the correction steel plate 1 is aligned with the bottom right angle of the steel beam. Then, by rotating the bolt to adjust the position of the nut, the correction steel plate is displaced accordingly to adjust and correct the misalignment of the steel beam.

[0008] Optionally, the corrective steel plate is a 4cm × 3cm rectangular plate with a 2cm × 1cm rectangular corner removed. This shape of material is easy to find on steel structure construction sites and can be made using scrap materials, which is economical and convenient.

[0009] Optionally, the bolt is 6cm long and 1.2cm in diameter, and the inner diameter of the nut is matched with the diameter of the bolt. The standardized dimensions ensure good fit accuracy and transmission efficiency between the bolt and the nut. The reserved 0.5cm distance provides the necessary travel space for adjustment and avoids the mechanism from jamming. This means that the adjustment process is smooth and stable, making fine adjustment possible. The mechanical performance of the device is optimized through precise size control to ensure reliability and adjustment accuracy. Furthermore, the nut is 1cm long and the vertical distance between it and the straightening steel plate is 0.5cm.

[0010] Optionally, the length of the threaded steel bar is 6cm, and one end of the bolt is fixedly connected to the middle of the threaded steel bar to increase the torque when tightening the bolt and make it easier to adjust the screw's entry and exit, thereby facilitating the adjustment of the steel beam's misalignment.

[0011] Optionally, the correction steel plate and the nut are fixedly connected by welding, and the bolt and the threaded steel bar are fixedly connected by welding. Welding provides a strong and immovable connection, which can reliably transmit the force and torque generated during the correction process, prevent relative displacement or loosening of the components during use, and ensure the structural integrity and operational reliability of the entire device.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0019] like Figure 1 and Figure 2 As shown, a device for adjusting the misalignment of a steel beam includes a nut 2 fixedly connected to one side of a correction steel plate 1, a bolt 3 threadedly connected to the nut 2, and a threaded steel bar 4 fixedly connected to the end of the bolt 3. The structure is simple. The screw's vertical displacement is adjusted by rotating the ordinary screw through the threaded steel bar 4, which facilitates the adjustment of the misalignment of the steel beam to meet the allowable range of the acceptance specifications. Moreover, the materials are readily available and can be made using scrap materials. It is simple, convenient, and allows for quick adjustment.

[0020] like Figure 1 and Figure 2 As shown, the correction steel plate 1 is in the shape of a "7". By setting the correction steel plate 1 to the shape of a "7", when correcting the misalignment of the steel beam, the inner right angle of the correction steel plate 1 is aligned with the bottom right angle of the steel beam. Then, by rotating the bolt 3 to adjust the position of the nut 2, the correction steel plate 1 is displaced accordingly to adjust and correct the misalignment of the steel beam.

[0021] like Figure 2 As shown, the corrective steel plate 1 has an external dimension of 4cm × 3cm rectangular plate with a 2cm × 1cm rectangular corner removed. This shape of material is easy to find on the steel structure construction site and can be made using scrap materials, which is economical and convenient. Example 2

[0022] like Figure 2 As shown, bolt 3 is 6cm long and 1.2cm in diameter. The inner diameter of nut 2 is compatible with the diameter of bolt 3. The standardized dimensions ensure good fit and transmission efficiency between the bolt and nut. The reserved 0.5cm distance provides the necessary travel space for adjustment and avoids the mechanism from jamming. This means that the adjustment process is smooth and stable, making fine adjustment possible. The mechanical performance of the device is optimized through precise size control to ensure reliability and adjustment accuracy. Furthermore, the nut is 1cm long and its vertical distance from the straightening steel plate 1 is 0.5cm.

[0023] like Figure 2 As shown, the length of the threaded steel bar 4 is 6cm. One end of the bolt 3 is fixedly connected to the middle of the threaded steel bar 4, which increases the torque when tightening the bolt and makes it easier to adjust the screw's entry and exit, thus facilitating the adjustment of the steel beam's displacement. Example 3

[0024] like Figure 1 and Figure 2 As shown, the alignment steel plate 1 and nut 2 are fixedly connected by welding, and the bolt 3 and threaded steel bar 4 are fixedly connected by welding. Welding provides a strong and immovable connection, which can reliably transmit the force and torque generated during the alignment process, prevent relative displacement or loosening of the components during use, and ensure the structural integrity and operational reliability of the entire device.

[0025] The working principle of this utility model is as follows: The materials are readily available and readily found on construction sites, and the construction is simple. Traditional methods of adjusting steel beam misalignment require a large amount of manpower and equipment such as jacks, and the process is cumbersome and difficult to implement. This device increases the torque by lengthening the threaded steel at the end, and controls the misalignment distance between the mating steel plates by adjusting the offset through bolts. It is also easy to disassemble, making it convenient for on-site workers to implement, and it has a good effect on adjusting the misalignment.

[0026] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
