[0016] The following will be combined with the accompanying drawings of the utility model to clearly and completely describe the technical solution of the utility model. It is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the utility model. In the description of the utility model, it should be noted that the terms "upper", "lower", "inside", "outside" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when used, which is only for the convenience of describing the utility model or simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0017] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] See also Figure 1 to Figure 3 The utility model is an adjustable end plate welding anti-deformation correction tool, comprising a first clamping jaw 1, a second clamping jaw 5 and a telescopic component, wherein the first clamping jaw and the second clamping jaw are respectively used to clamp the end plate 8 of the steel member and a web of a cross-shaped steel column, and the telescopic component comprises two connecting screws 3 and an intermediate driving body, wherein the two connecting screws are respectively threadedly connected to the two ends of the intermediate driving body, and the intermediate driving body simultaneously drives the two connecting screws to synchronously shrink toward the middle or extend to both sides; the outer ends of the two connecting screws are respectively connected to the first clamping jaw and the second clamping jaw.

[0019] Furthermore, the intermediate driving body in this embodiment is composed of a long rectangular frame 4, the middle of the long rectangular frame is hollow, and the two ends of the long rectangular frame are respectively threaded with two connecting screws, and the threads on the two connecting screws have opposite rotation directions. Furthermore, the intermediate driving body in the utility model can also be made of a threaded sleeve, and the threads in the threaded sleeve are divided into two sections of threads with opposite rotation directions.

[0020] In practical applications, both of the above methods can be selected and used according to actual conditions. However, if a threaded sleeve is used, it is best to drill a hole in the middle of the threaded sleeve to facilitate the insertion of the steel rod.

[0021] Furthermore, in this embodiment, a connecting screw is welded to the top of the second clamping jaw, and another connecting screw is rotatably connected to the first clamping jaw through a rotating shaft. Furthermore, in the utility model, the first clamping jaw is arranged in a vertical U-shaped structure 6, and the opening of the vertical U-shaped structure is arranged downward. Further, in the utility model, the second clamping jaw is arranged in a transverse U-shaped structure 7, and the opening of the transverse U-shaped structure is arranged in a forward or backward direction. Further, the U-shaped opening in the transverse U-shaped structure in the utility model adopts a flat plate opening shape.

[0022] When the utility model is actually used, it is used in conjunction with the end plate welding, and the specific operation is as follows:

[0023] First, the end plate and the cross-shaped steel column are spot welded and preliminarily fixed. Then, the tool of the utility model is started. The first clamp is clamped on the end plate, and the second clamp is clamped on the side edge of the web of the cross-shaped steel column. Since the bayonet of the transverse U-shaped structure is attached to the edge of the web, it will be naturally clamped. Then, a steel rod or a rod is inserted into the long rectangular frame 4 and rotated. Through the rotation of the long rectangular frame, the two connecting screws are tightened synchronously so that the two connecting screws are contracted and tightened toward the middle synchronously, until the end plate and the steel column are at a vertical angle of 90 degrees. Then, full welding is performed to completely weld the entire end plate and the end of the steel column into one.

[0024] In the above process, two sets of the tool of the utility model can be used simultaneously to clamp the web plate and the end plate from both sides.

[0025] The utility model can also be used for the later correction work of the welded end plate. After the end plate is welded, if it is found that the end plate is bent and deformed, the tool of the utility model is added, and then the long rectangular frame is rotated, and the two connecting screws are pulled to the middle synchronously, and then fixed for a period of time. Through the toughness of the steel plate itself, it corrects itself after being fixed for a period of time. It is relatively flexible to use.

[0026] The utility model designs a set of simple and easy-to-operate clamping tools, which are used in conjunction with welding the end plates, thereby preventing welding deformation and playing a certain corrective role on the end plates during or after welding, and has good practical promotion and use value.
