[0002] Steel structures are usually composed of columns, beams, trusses, plates and other components made of steel plates and steel sections. The various parts are spliced ​​by welding, riveting or bolting to form the main frame of the building. Compared with building structures made of other materials, the advantages of steel structures are: high strength and light weight. Under the same force, the steel structure has a small deadweight, can build a structure with a large span, and has good seismic performance; due to the weldability of steel, the connection of steel structures is greatly simplified, which is suitable for manufacturing structures of various complex shapes; the manufacture of steel structure components is mainly carried out in specialized metal component factories, which are convenient to manufacture, high in precision, high in degree of on-site assembly, and short in construction period. Among them, rectangular steel structure components usually require multiple sections of small rectangular steel structure components to be welded to obtain, but during the welding process, there is a certain probability that the welding part of the steel structure component will bend, resulting in the quality of the rectangular steel structure component not meeting the standard. Therefore, a steel structure component welding deformation correction device is needed to correct the steel structure component.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1-3 As shown, the utility model provides a technical solution: it includes a correction component 1, a limit component 2 is arranged above the correction component 1, the correction component 1 includes a correction plate 101, a clamping plate 102 is fixedly installed on the front of the correction plate 101, a chuck groove 103 is opened on the top surface of the clamping plate 102, a fixing plate 104 is slidably installed on the bottom surface of the chuck groove 103, a fixing screw 105 is threadedly inserted in the middle of one side of the clamping plate 102, one end of the fixing screw 105 is rotatably connected to one side of the fixing plate 104, a correction groove 106 is opened on the top surface of the correction plate 101, a correction cylinder 107 is fixedly installed in the middle of one side of the correction plate 101, one end of the piston rod of the correction cylinder 107 extends into the correction groove 106, and a correction pressure plate 108 is fixedly installed on one end of the extended piston rod of the correction cylinder 107;

[0019] The limiting assembly 2 includes a top plate 201, a limiting cylinder 202 is fixedly installed in the middle of the top surface of the top plate 201, the bottom end of the piston rod of the limiting cylinder 202 extends below the bottom surface of the top plate 201, and a limiting plate 203 is fixedly installed at the bottom extension end of the piston rod of the limiting cylinder 202.

[0020] In this embodiment, a vertical slider 206 is fixedly installed in the middle of both side surfaces of the limit plate 203. The two vertical sliders 206 correspond to the two vertical grooves 205 one by one. The vertical sliders 206 are slidably installed in the vertical grooves 205. A vertical plate 204 is fixedly installed on both sides of the bottom surface of the top plate 201. The middle of both side surfaces of the correction plate 101 are respectively fixedly connected to the inner side surfaces of a vertical plate 204 to make the lifting and lowering of the limit plate 203 more stable.

[0021] The limit plate 203 is located directly above the correction groove 106, and the width of the limit plate 203 is greater than the width of the chuck groove 103 and the correction groove 106. The limit plate 203 is lowered to limit the steel structure component to avoid the correction failure caused by the upward deviation of the steel structure component when the correction pressure plate 108 is correcting the steel structure component.

[0022] When in use, the steel structure component to be corrected is taken out, and then one end of the steel structure component is placed in the chuck groove 103.

After fixing, the limit cylinder 202 is started, and the limit cylinder 202 can drive the limit plate 203 to descend. The limit plate 203 descends and can contact the top surface of the steel structure, so that it can be limited. In order to avoid the upward deviation of the steel structure component and the failure of correction when the correction plate 108 is used to correct the steel structure component, after the steel structure component is limited from above, the correction cylinder 107 is started. Under the action of the correction cylinder 107, the correction plate 108 will move toward the steel structure component. The correction plate 108 can be used to push the bent part of the steel structure component, thereby pressing the bent part of the steel structure component caused by welding, thereby completing the rapid correction operation of the steel structure component.

[0023] To sum up, the steel structure component welding deformation correction device can limit the steel structure component by lowering the limit plate 203, so as to prevent the correction plate 108 from shifting upward when correcting the steel structure component, resulting in correction failure. At the same time, under the action of the correction cylinder 107, the correction plate 108 will move toward the steel structure component, and the correction plate 108 can be used to push the bent part of the steel structure component, so that the bent part of the steel structure component caused by welding can be pressed, so that the correction operation of the steel structure component can be completed quickly, effectively improving the correction efficiency of the rectangular steel structure component, and being more practical.
