The platform 1 is rectangular, and wheels 2 are installed at each of its four corners. At least two of the wheels 2 are equipped with brakes for easy movement and welding. A support device and a clamping device are detachably fixed to the top of the platform 1. The clamping device works in conjunction with the support device to keep the steel structural component 11 in a relatively stable position. The support device includes several spaced support components 3, which provide stable support for the steel structural component 11. Each support component 3 includes a support rod 5 detachably fixed to the top of the platform 1. A horizontal support column 27 is fixed to the support rod 5. A support sleeve 6 is fitted onto the support column 27. A vertical support platform 7 is fixed to the end of the support sleeve 6 facing away from the support rod 5. A first locking bolt 8 is threaded onto the support platform 7. The end of the support column 2 facing away from the support rod 5 contacts the back of the support platform 7. The support platform 7 and the support column 27 are detachably fixedly connected by the first locking bolt 8, which facilitates installation and disassembly. At least one side of the support platform 7 is provided with a first arc-shaped groove 25, which is mainly used to support steel structural members 11 with a circular or annular cross-section. The other sides of the support platform 7 are flat, which is mainly used to support steel structural members 11 with flat sides, such as steel columns with a rectangular or square cross-section. The sides of the support sleeve 6, the support column 27 and the support platform 7 are all one-to-one, that is, the number of sides of the support sleeve 6, the support column 27 and the support platform 7 are all the same and one-to-one. After selecting a suitable side of the support platform 7 as the support surface, it is easy to quickly install the support sleeve 6 on the support column 27. The tightening device includes a height-adjustable mounting frame, which is convenient to adjust the height of the mounting frame according to the specifications of the steel structural member 11. The middle of the mounting frame is provided with a top tightening component 13 that can move up and down, which is used to tighten it on the top of the steel structural member 11.
[0021] The support platform 7 has four sides, two of which have first arc-shaped grooves 25. The two first arc-shaped grooves 25 can be the same or different to facilitate the support of different steel structural components 11. The support sleeve 6 and the support column 27 also have four sides. The support sleeve 6 has a mounting hole 26 in the middle that mates with the support column 27.

The top of the vertical column 17 is detachably fixed to the bottom of the top plate 12. When it is necessary to adjust the height of the outrigger 4, the second locking bolt 18 is loosened, the vertical column 17 is moved up and down to the appropriate height, and then the second locking bolt 18 is tightened.
[0025] Fixing plates 28 are fixed to the outer side of the sleeve 19 and the outer side of the support rod 5. The fixing plates 28 are detachably fixed to the vehicle plate 1 by bolts, which facilitates installation and disassembly.
[0026] The vehicle panel 1 has a horizontal connecting hole, and a connecting rod 9 is slidably connected in the connecting hole. One end of the connecting rod 9 extends out of the connecting hole. Symmetrical third locking bolts 10 are threaded on the side of the vehicle panel 1. The inner end of at least one third locking bolt 10 is pressed against the corresponding connecting rod 9. When the two vehicle panels 1 transporting the steel structure component 11 are docked, the connecting rod 9 on one of the vehicle panels 1 is extended to a suitable length, and then the corresponding third locking bolt 10 is tightened to lock the extension length of the connecting rod 9. During the docking process, the connecting rod 9 is inserted into the connecting hole of the other vehicle panel 1, which facilitates the docking of the steel structure component 11 on the two vehicle panels 1. After the two steel structure components 11 are docked, the corresponding third locking bolt 10 on the other vehicle panel 1 is tightened to connect the two vehicle panels 1 together, which facilitates welding and other operations.
[0027] At least two pallets 1 are selected, one for transporting the other for transporting the two steel structural components 11 that need to be joined. The number of pallets 1 can be increased as needed. During use, according to the cross-sectional shape of the steel structural component 11, a suitable support platform 7 side is selected as the support surface. Loosen the first locking bolt 8, remove the support platform 7, adjust the position of the support platform 7 so that the support surface of the support platform 7 faces upward, and then fit the support sleeve 6 onto the support column 27. Tighten the first locking bolt 8 for easy installation and disassembly. Place the steel structural component 11 to be joined on top of the pallet 1, with the bottom of the steel structural component 11 in contact with the support surface of the support platform 7. Then, follow the above operation to tighten the clamping block 21 of the clamping device onto the top of the steel structural component 11. Finally, adjust the position of the two pallets 1 to complete the joining.
