Description

Technical Field

[0001] The utility model relates to a tower platform beam installation tool, in particular to a temporary fixing and correction device for installing an H-steel beam. Background Art

[0002] During the installation of the platform beam of the wind power steel tower, the control of the connection nodes between beams and columns has always been a key point in the installation and construction of the steel tower. In previous projects, the control of the installation nodes of beams and columns has always been achieved by using a crane for initial installation, manual secondary correction, and welding construction. This method has the following defects.

[0003] (1) Crane use: During construction, the crane needs to use the lifting belt to hold the flat beam for a long time, and the lifting belt can only be unhooked after the steel beam is installed and welded. The crane is used for a long time. During the installation and welding process of the steel beam, the steel beam is easily disturbed and shifted, and there is a risk of the crane lifting belt breaking.

[0004] (2) Construction personnel: During construction, construction workers need to adjust the position of steel beams based on their construction experience. The construction accuracy is difficult to control. If the operation is not standardized or the quality awareness is not strong, the position of the steel beams may easily shift.

[0005] In view of the above, it is necessary to find a solution to the problem during the construction process. For example, if the position of the steel beam is offset during the construction process, it is easy to change the force form of the beam-column node, causing the platform to tilt and become unstable, and there are quality risks such as structural safety. The temporary fixing and correction device installed on the H-beam can effectively and easily solve the above problems. Its working principle is the coordination of the fixing fixture and the fine-tuning device. This device consists of three parts, namely the fixing fixture, the fine-tuning device, and the supporting structure. Utility Model Content

[0006] The purpose of the utility model is to provide a temporary fixing and correction device for the installation of H-steel beams, which overcomes the shortcomings of the existing technology and adopts a column fixing fixture, a beam fixing fixture and a fine-tuning device to align and correct the welding of the H-shaped steel beam and the column to achieve accurate and safe effects.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A temporary fixing and correction device for installing an H-beam, comprising:

[0009] Support part, used for bearing and positioning;

[0010] A beam fixing fixture is provided at the top of the support portion and is used to fix the H-steel beam, comprising a hoop plate I with a rectangular cross section, two wing plates I, at least one rib plate and a fixing bolt I, wherein the ends of the hoop plate I are integrally formed with the two wing plates I, one side of the middle portion of the hoop plate I is fixedly connected to the support portion, and the other side is reinforced by the rib plate, and the wing plate I is provided with a screw hole for the fixing bolt I to pass through, so as to adjust the position of the fixed H-steel beam;

[0011] A column fixing fixture is fixed to the side end of the support portion and is used to fix the column. It includes a hoop plate II with a circular cross section, two wing plates II, and a fixing bolt II. The two ends of the hoop plate II are respectively integrally formed with the two wing plates II. The middle part of the hoop plate II is fixedly connected to the support portion. The wing plate II is provided with a screw hole for the fixing bolt II to pass through, which is used to adjust and fix the position of the column.

[0012] The fine-tuning device is arranged at the top of the support part and is used to fine-tune the position of the H-steel beam. It includes a base plate, two side plates, several fine-tuning ribs and several fine-tuning bolts. The base plate is arranged at the top of the support part and is connected to the side plates on both sides. The base plate is provided with screw holes and is connected to the fine-tuning ribs through fine-tuning bolts. The side plates are also provided with screw holes for realizing the lateral position adjustment of the H-steel beam through fine-tuning bolts.

[0013] Furthermore, the number of the ribs is three.

[0014] Furthermore, the number of the fine-tuning bolts is twelve, six of which are used for fine-tuning the longitudinal position adjustment of the rib plate, and the other six are used for lateral position adjustment of the side plate to ensure accurate correction of the position of the H-beam.

[0015] Furthermore, the width of the cross section of the hoop plate I is 2 mm larger than the width of the cross section of the H-shaped steel beam; the width of the cross section of the hoop plate II is 4 mm larger than the diameter of the column cross section, and the width of the bottom plate is 4 mm larger than the width of the cross section of the H-shaped steel beam. Beneficial effects

[0016] 1. Precise control of fine-tuning function: A fine-tuning device with a width set to (B1+4mm) and equipped with six fine-tuning bolts on the bottom plate and twelve fine-tuning bolts on the side plates allows for extremely precise position adjustment of the H-beam, ensuring height alignment with the column welding points, reducing secondary work and potential safety hazards caused by position deviation;

[0017] 2. Dual guarantee of safety and durability: All components of the device, such as hoops, flanges, and ribs, are made of high-strength materials and firmly connected by fixing bolts. This not only enhances the stability of the overall structure, but also can withstand various external forces and impacts at the construction site, extending its service life.

[0018] 3. Simplified installation process: The operation method is simple and clear. By fixing the column first and then fine-tuning the position of the H-steel beam, the tedious trial and error process in traditional installation is avoided, which greatly saves labor costs and reduces the difficulty of construction.

[0019] Prevention of welding defects: Special emphasis is placed on the inspection and adjustment steps - before final welding, the fine-tuning bolts are loosened one by one to check the offset of the H-beam relative to the weld point, and unqualified components are corrected or replaced in a timely manner, effectively avoiding weld damage caused by excessive shear stress and ensuring welding quality and structural safety.
