The sleeve shaft 30 is connected to the support plate 26 or the hollow plate 27. The support plate 26 and the hollow plate 27 are located on the inner side of the first sliding arc plate 18 and the second sliding arc plate 19. A plurality of sixth springs 29 are connected between the hollow plate 27 and the second sliding arc plate 19.

[0019] In the present embodiment, considering that it is difficult to align the ribs or reinforcing ribs to the correct welding position, a steel structure welding device for construction of the present invention is provided. When welding, first, the device is placed on the horizontal plate 13 of the steel structure, and the device is pushed to the position where welding is required by the moving wheel 14. The final stop position of the base 11 can be calculated and fixed, and then the telescopic member 1 is started to drive the top plate 17 to move upward. When the bottom of the support plate 26 and the hollow plate 27 are just located above the ribs, the telescopic member 1 is used to drive the top plate 17 to move downward. At this time, the bottom of the support plate 26 and the hollow plate 27 contact the ribs. When the downward movement continues, the ribs enter between the support plate 26 and the hollow plate 27, and the support plate 26 rotates toward the first sliding arc plate 18, and the hollow plate 27 rotates toward the second sliding arc plate 19 until the top plate 17 is moved downward. The support plate 26 and the hollow plate 27 are attached to and squeezed on the two side surfaces of the rib plate. In this state, the top plate 17, the first side arc plate 15 and the second side arc plate 16 continue to descend. When they reach a certain height, the storage assembly 6 drives the moving wheel 14 to be recovered, so that the suction cup 5 is in contact with the cross plate 13 of the steel structure, and the device as a whole is fixed by the suction cup 5. At this time, the top plate 17 just completely contacts the top of the rib plate, so that the rib plate can be fixed from both sides and ends of the rib plate. The top plate 17 squeezes the end of the rib plate, so that the other end of the rib plate can be pressed against the cross plate 13 of the steel structure. After the rib plate is fixed, the rib plate can be welded and fixed. After the welding on one side of the rib plate is completed, the telescopic member 1 is started to make the support plate 26 and the hollow plate 27 move away from the rib plate, and the base 11 is withdrawn, so that welding on the other side can be carried out.

[0020] The squeezing effect of the support plate 26 and the hollow plate 27 can cause the ribs to maintain a vertical state with the cross plate 13. By placing the entire device on the cross plate 13 of the steel structure and moving it on the cross plate 13 through the moving wheels 14, the ribs can be kept vertical with the cross plate 13. In addition, through the cooperation of the storage component 6 and the suction cup 5, the base 11 and the cross plate 13 can be fixed by the suction cup 5, thereby avoiding the ribs from shifting during the welding process and omitting the operation of manually supporting the ribs.

[0021] See also Fig.10 , Fig.11 In one embodiment, one end of the support plate 26 located outside the first sliding arc plate 18 is connected to the first flat plate 23, and one end of the hollow plate 27 located outside the second sliding arc plate 19 is connected to the second flat plate 24.

[0026] A second spring 21 and a third spring 22 are provided to prevent the rib end from being offset, thereby ensuring that the rib is always located at the center of the first side arc plate 15 and the second side arc plate 16 .

[0027] See also Figure 7 , Figure 8 In one embodiment, wedge plates 10 are slidably mounted on both sides of the top plate 17 , and a plurality of fourth springs 25 are connected between the top plate 17 and the wedge plates 10 .

[0028] In this embodiment, the top plate 17 is driven downward by the telescopic member 1. At this time, the bottom of the support plate 26 and the hollow plate 27 contact the rib plate. When the downward movement continues, the rib plate enters between the support plate 26 and the hollow plate 27, and the support plate 26 rotates toward the first sliding arc plate 18, and the hollow plate 27 rotates toward the second sliding arc plate 19 until the support plate 26 and the hollow plate 27 are attached to and squeezed on both sides of the rib plate. In this state, the top plate 17, the first side arc plate 15 and the second side arc plate 16 continue to descend. When the end of the rib plate passes through the wedge plates 10 on both sides, the rib plate can be squeezed and clamped by the wedge plates 10 on both sides.

At this time, the top plate 17 just completely contacts the top of the rib plate, so that the rib plate can be fixed from both sides and ends of the rib plate. The end of the rib plate is squeezed by the top plate 17, so that the other end of the rib plate can be close to the cross plate 13 of the steel structure. After the rib plate is fixed, the rib plate can be welded and fixed. After the welding on one side of the rib plate is completed, the telescopic member 1 is started to make the support plate 26 and the hollow plate 27 move away from the rib plate, and the base 11 is withdrawn, so that welding on the other side can be performed.

[0030] In this embodiment, the top plate 17 is driven downward by the telescopic member 1. At this time, the bottom of the support plate 26 and the hollow plate 27 contact the rib plate. When the downward movement continues, the rib plate enters between the support plate 26 and the hollow plate 27, and the support plate 26 rotates toward the first sliding arc plate 18, and the hollow plate 27 rotates toward the second sliding arc plate 19 until the support plate 26 and the hollow plate 27 are attached to and squeezed on both sides of the rib plate. In this state, the top plate 17, the first side arc plate 15 and the second side arc plate 16 continue to descend. When the end of the rib plate passes through the wedge plates 10 on both sides and contacts the top contact plate 8, the rib plate can be squeezed and clamped by the wedge plates 10 on both sides. At this time, the storage component 6 drives The moving wheel 14 is recovered, so that the suction cup 5 is in contact with the horizontal plate 13 of the steel structure, so that the entire device is fixed by the suction cup 5. At this time, due to the recovery of the moving wheel 14, the top plate 17 continues to descend, so that the first spring 9 is squeezed to the limit position. Therefore, the end of the rib plate can be further squeezed and fixed with the help of the first spring 9. The end of the rib plate is squeezed by the top plate 17, so that the other end of the rib plate can be pressed against the horizontal plate 13 of the steel structure. After the rib plate is fixed, the rib plate can be welded and fixed. After the welding on one side of the rib plate is completed, the telescopic member 1 is started to make the support plate 26 and the hollow plate 27 move away from the rib plate, and the base 11 is withdrawn, so that welding on the other side can be carried out.
