After the error meets the requirements, they are temporarily fixed with steel plates before welding. During the on-site alignment of the upper and lower steel structure columns, the steel plates are first welded and fixed to the corresponding positions of the upper and lower steel structure columns; then, with the help of jacks and other equipment, the upper steel structure column is adjusted until the steel structure columns are aligned up and down; then the steel plate on the upper structure column and the steel plate on the lower steel structure column are fixedly connected through the center plate to achieve temporary fixation between the upper and lower steel structure columns.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 6 As shown, an embodiment of the present invention provides a steel column butt-jointed fixing structure, which includes: a U-shaped steel frame 1, a U-shaped extension frame 2 and a center connecting plate 6.

[0024] Specifically, such as Figures 1 to 5 As shown, a U-shaped extension frame 2 is movably provided in the U-shaped steel frame 1, and the U-shaped extension frame 2 is slidably installed in the U-shaped groove 1a opened in the U-shaped steel frame 1; the outer corners of the U-shaped steel frame 1 are fixedly embedded with welding ridges 11 to adapt to the shape of the steel column and facilitate welding with the steel column; bolt through holes 1b are opened on both side panels of the U-shaped steel frame 1; the outer corners of the U-shaped extension frame 2 near the top are fixedly welded with welding ridges 21 to adapt to the shape of the steel column and facilitate welding with the steel column; and the U Both side panels of the U-shaped extension frame 2 are provided with waist-shaped through-holes 2a. A center plate 6 is inserted into the U-shaped steel frame 1, and a plurality of center holes 6a are provided on the center plate 6 at equal intervals. Fastening bolts 7 for connecting the center plates 6 are mounted on the U-shaped steel frame 1. Some fastening bolts 7 pass through the bolt through-holes 1b and the waist-shaped through-holes 2a and are threadedly connected to the center holes 6a on the center plate 6. Other fastening bolts 7 pass through the waist-shaped through-holes 2a and are threadedly connected to the center holes 6a on the center plate 6. The U-shaped steel frame 1 is welded to the lower steel column via welded ribs 11, and the U-shaped extension frame 2 is welded to the upper steel column via welded ribs 21. The U-shaped steel frame 1 and the U-shaped extension frame 2 are fixed together via the center plate 6, ultimately achieving a temporary docking fixation between the upper and lower steel columns to facilitate subsequent welding work.

[0025] In some embodiments, a pressing plate 3 for abutting the U-shaped extension frame 2 is provided in the U-shaped steel frame 1, and the pressing plate 3 is elastically installed in the middle groove area of ​​the U-shaped groove 1a; a plurality of springs 4 are provided in the middle groove area of ​​the U-shaped groove 1a, one end of the spring 4 is fixedly connected to the inner wall of the U-shaped groove 1a, and the other end of the spring 4 is fixedly connected to the plate wall of the pressing plate 3; a threaded hole 1c is provided on the inner plate wall near the top of the U-shaped steel frame 1, which is interconnected with the middle groove area of ​​the U-shaped groove 1a, and a push screw 5 is threadedly connected to the threaded hole 1c, and the end of the push screw 5 is in contact with the U-shaped extension frame 2. When the push screw 5 is screwed in, the push screw 5 pushes the U-shaped extension frame 2, thereby pushing the pressing plate 3 to compress the spring 4, thereby realizing the movement of the U-shaped extension frame 2 toward the steel column.

[0026] In some embodiments, waist-shaped through holes 2a are provided on both side panels of the U-shaped extension frame 2, so that when the advancing screw 5 pushes the U-shaped extension frame 2 to move along the middle groove area of ​​the U-shaped groove 1a toward the steel column, the fastening bolts 7 can still fix the U-shaped extension frame 2 through the waist-shaped through holes 2a.

[0027] In some embodiments, two butt-jointed fixing structures can also be used to temporarily reinforce the upper and lower steel columns: specifically, after welding the two U-shaped steel frames 1 to the upper and lower steel columns respectively, there is no need to slide the U-shaped extension frame 2 inside the U-shaped steel frame 1 outward, and then insert the middle connecting plate 6 into the two U-shaped steel frames 1 and then fix the middle connecting plate 6 by tightening bolts 7 (as shown in the attached figure). Figure 6 shown).

[0028] The working principle of the steel column docking fixing structure provided by the utility model is as follows:

[0029] During the upper and lower splicing, alignment and welding process of the steel structure columns, in order to ensure the alignment of the upper and lower steel structure columns, it is necessary to first use a jack and a total station to adjust until the upper and lower steel structure columns are aligned. After the error meets the requirements, they are temporarily fixed with a U-shaped steel frame 1 before welding operations are carried out.

[0030] The specific operation is: stick the plate wall of the U-shaped steel frame 1 with the welding protrusion 11 to the welding end of the lower steel column and make the welding protrusion 11 against the lower steel column. After keeping the top of the U-shaped steel frame 1 in a horizontal state, use a welding machine to fix the welding protrusion 11 and the lower steel column.

[0031] Subsequently, the U-shaped extension frame 2 is slid up along the U-shaped steel frame 1 until the welding ribs 21 on the U-shaped extension frame 2 correspond to the welding area of ​​the upper steel column, and the advancing screw 5 is screwed in so that the U-shaped extension frame 2 pushes the pressing plate 3 and compresses the spring 4. When the welding ribs 21 on the U-shaped extension frame 2 fits the upper steel column, the welding ribs 21 are welded to the upper steel column by a welding machine, thereby completing the connection between the U-shaped steel frame 1 and the upper and lower steel columns; after completion, the middle connecting plate 6 is inserted from the U-shaped extension frame 2 into the U-shaped steel frame 1, and then the fastening bolts 7 are used to fix the middle connecting plate 6 to the U-shaped extension frame 2 and the U-shaped steel frame 1 respectively, thereby completing the temporary fixation before welding the upper and lower steel columns.

[0032] The present application provides welding ridges 11 and welding ridges 21 on the U-shaped steel frame 1 and the U-shaped extension frame 2, which facilitates the welding of the U-shaped steel frame 1 and the U-shaped extension frame 2 to the upper and lower steel columns. At the same time, the U-shaped steel frame 1 and the U-shaped extension frame 2 can be flexibly adjusted in length, so they can be stored when not in use. When in use, the U-shaped extension frame 2 is slid out of the U-shaped steel frame 1, and the welding ridges 11 on the U-shaped steel frame 1 are welded to the lower steel column, while the welding ridges 21 on the U-shaped extension frame 2 are welded to the upper steel column. Due to the sliding connection between the U-shaped steel frame 1 and the U-shaped extension frame 2, there will be no misalignment between the U-shaped steel frame 1 and the U-shaped extension frame 2 after they are respectively welded to the upper steel column and the lower steel column.

[0033] Each embodiment in this specification is described in a related manner. The same or similar parts between the embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
