[0002] During the on-site installation of steel truss bridges in the field of steel structure manufacturing, the webs of the beams are prone to local deformation due to their own structural characteristics and weight. Currently, the common adjustment method on-site at the bridge site is to use spot welding of steel supports, assisted by jacks or hand hoists to adjust the deformation of the beam webs. Although this operation method is relatively common, it requires the use of jacks and hand hoists for spot welding and fixing, which will cause damage to the steel components. In addition, it is a high-altitude operation at the bridge site, which is inefficient and difficult to implement.

[0003] As can be seen, the current method is not only limited in operation and spot welding can damage steel components, but also requires a large amount of labor and various fees for welding and repainting, is inefficient, and also hides safety and quality risks. Therefore, how to adjust steel components while avoiding structural damage and reducing paint damage; how to complete construction work safely and efficiently have become urgent issues to be solved. Therefore, it is urgent to develop a reusable and low-cost device that can meet the construction requirements of similar components and similar occasions in the future. Utility Model Content

[0005] Technical solution: The utility model includes a plate hook, a connecting piece and a dynamic telescopic mechanism. A plate hook is provided on one side of the connecting piece, and the other side is connected to the dynamic telescopic mechanism. The plate hook is connected to the end of the dynamic telescopic mechanism away from the connecting piece. The plate hooks on both sides are respectively mounted in the U-rib grooves of the beam on the corresponding sides, and the grooves of the plate hooks clamp the webs of the beams on both sides. The deformation adjustment of the beam is achieved through the relative rotation and extension of the dynamic telescopic mechanism.

[0006] The dynamic telescopic mechanism includes a bolt and a screw rod, the bolt and the screw rod are threadedly connected, one end of the screw rod is connected to the connecting piece, and the other end is connected to the bolt, and a plate hook is fixed to the end of the bolt away from the screw rod.

[0007] The bolt is a turnbuckle bolt.

[0008] The basket bolts and screws can realize the extension and retraction of the tooling. The extension and retraction range is related to different beam spacings and can be adjusted. The basket bolts and screws must meet strength requirements.

[0009] The plate hook is a steel plate with a thickness of 12-16 mm and a material not lower than Q235.

[0010] The plate hook is flame cut.

[0011] The connecting piece is replaced by connecting channel steel or steel materials with equal rigidity, such as I-beam, round pipe, angle steel and other existing materials.

[0012] A crossbeam using a non-destructive adjustment tool for deformation of a steel truss crossbeam comprises a plurality of groups of crossbeams arranged opposite to each other. A non-destructive adjustment tool is mounted between each group of crossbeams. The plate hooks on both sides of the non-destructive adjustment tool are respectively mounted in the U-rib notches of the crossbeams on the corresponding sides, and the notches of the plate hooks clamp the webs of the crossbeams on both sides. The tensioning or pushing-opening adjustment of the crossbeams on both sides is achieved through the relative rotation and extension of the dynamic telescopic mechanism. The screw operation can be stopped after the crossbeam spacing is adjusted to the theoretical distance.

The webs of the beams on both sides are clamped through the notches of the plate hooks. Finally, the deformation of the beams is adjusted by the relative rotation and extension of the basket bolts and the screw rod, thereby meeting on-site needs.
