[0018] See Figures 1 to 3 , the present utility model is a cross-shaped steel column erection and welding anti-deformation device, which has a base plate 1. Further, in the present utility model, the base plate is made of a thick and wide steel plate, and a rectangular frame 4 is welded on the upper surface of the base plate. The rectangular frame is arranged vertically, and a set of pressing mechanisms 3 are provided in each of the left, right, and upper directions of the rectangular frame. The pressing mechanisms on the left and right sides are symmetrically arranged, and the pressing mechanism located above is in the middle and arranged vertically downward; further, in the present utility model, a fixed bottom groove 2 is provided on the inner bottom surface of the rectangular frame, and this fixed bottom groove is used for clamping steel plates, specifically for clamping the middle vertical steel plate. The fixed bottom groove and the pressing mechanism above are arranged vertically opposite to each other; the pressing mechanism has a pressing screw 8, and a rotating handle 12 is provided at the outer end of the pressing screw. Further, in the present utility model, the rotating handle adopts a cross-shaped handle or a circular ring handle, and a pressing block 7 is provided at the inner end of the pressing screw, and the pressing block is placed inside the rectangular frame. Further, in the present utility model, the pressing block is rotatably connected to the corresponding pressing screw, and a rectangular clamping groove 6 is provided on the pressing contact surface of the pressing block.

[0019] The present utility model is a set of anti-deformation tooling made for the welding of cross-shaped steel columns. As Figure 4 shown, the cross-shaped steel column is composed of a middle vertical steel plate 9 and side steel plates 11 which are symmetrically arranged and welded on both sides. When erecting and welding the cross-shaped steel column, it is carried out as follows:

[0020] First, assemble the middle vertical steel plate and the side steel plates on both sides on an assembly machine. After assembly, perform local spot welding for shaping. Then, hoist it onto a certain operating table, and successively install multiple sets of the devices of the present invention on the preliminarily shaped cruciform steel column. Place the rectangular frames of the present invention at multiple positions in the front, middle, and rear. Clamp the bottom of the middle vertical steel plate in the cruciform steel column to the middle of the fixed bottom groove. Then, start adjusting the pressing mechanisms in the up, left, and right directions simultaneously, so that the pressing contact surfaces of the pressing blocks therein abut against the middle vertical steel plate and the side steel plates on the left and right sides. Tighten the pressing screw by turning the handle for pressing. After pressing, full-length welding can be carried out.

[0021] When in use, the anti-deformation device of the present invention is not used alone, but multiple devices are used in cooperation to clamp the steel plates to be welded. In this way, when welding the assembled steel plates later, the situation of welding deformation basically will not occur, and the welding quality is guaranteed.

[0022] As a simple tooling, the present invention can be completely fabricated in the workshop. The following base plate should preferably use a relatively thick and wide steel plate to facilitate stable placement and subsequent operations.
