[0021] 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.

[0022] The utility model provides a fixing and deviation-correcting device for welding the side plates of steel box beams, such as Figure 1-Figure 5 As shown, it includes a steel frame 4, a steel side plate 3 is installed at the bottom of one side of the steel frame 4, a nut 1 is arranged in the middle of the steel side plate 3, a bolt 2 is connected to the inner thread of the nut 1, a pressure plate 22 is installed at one end of the bolt 2, and the outer wall of the pressure plate 22, the steel frame 4 is sleeved in the middle of the column 5, the nut 1 on the steel side plate 3 rotates to drive the pressure plate 22 to press and position the steel box girder side plate, the steel frame 4 is adjusted in height by vertically sliding on the column 5, and is adjusted to the top of the device according to the different heights of the steel box girder side plates, so that the steel side plate 3 can press and position the steel box girder side plates.

[0023] In this embodiment, a pad 23 is installed on the outer wall of the pressure plate 22. The pad 23 is made of rubber material to ensure the compression and positioning of the side plate of the steel box beam.

[0024] Specifically, a handle 21 is installed at one end of the bolt 2 away from the pressure plate 22 to facilitate manual adjustment of the rotation of the bolt 2.

[0025] Furthermore, the columns 5 are located on the outside of the steel box girder side plates and are arranged at equal intervals to ensure that various parts of the outer wall of the steel box girder side plates are limited.

[0026] Furthermore, a nut hole is provided in the middle of the steel side plate 3 , and the nut 1 is welded and fixed at the nut hole, so as to facilitate the fixation of the nut 1 .

[0027] Furthermore, the steel side plate 3 is welded and fixed to one side of the steel frame 4, and the steel side plate 3 and the steel frame 4 are arranged perpendicular to each other, so as to facilitate the fitting of the steel side plate 3 and the steel box beam side plate.

[0028] Furthermore, inner grooves 41 are provided on the inner side walls on both sides of the steel frame 4, and movable plates 43 are provided inside the inner grooves 41. A plurality of springs 42 are installed at the bottom of the movable plates 43. Pressure is applied to the movable plates 43 by the springs 42, thereby generating a certain friction force between the movable plates 43 and the outer wall of the column 5, thereby ensuring the positioning of the steel frame 4.

[0029] Furthermore, the springs 42 are arranged at equal intervals to ensure stable support for the movable plate 43 .

[0030] When the fixing and deviation-correcting device for welding the steel box girder side plate of the utility model is used, firstly, the position of the steel frame 4 on the column 5 is adjusted according to the height of the steel box girder side plate, and the steel frame 4 is installed at the height position of the corresponding steel box girder side plate on the column 5 (it can be specifically adjusted according to the height of different steel box girder side plates to adapt to the welding of steel box girder side plates of different sizes). Use a ruler to measure the distance between the two side plates of the steel box girder and whether the linearity is straight. This step is continued until the welding work is completed. By vertically sliding the steel frame 4 on the column 5, it can be easily adjusted to an appropriate height. The steel side plate 3 is located at the steel box girder side plate and ensured to be close to the steel side plate 3. Subsequently, if the size and linearity do not meet the requirements, the handle 21 on the bolt 2 is rotated to drive the bolt 2 to rotate in the nut 1. Since a pressure plate 22 is installed at one end of the bolt 2, as the bolt 2 rotates, the pressure plate 22 will gradually press the steel box girder side plate to fix it. The pad 23 on the outer wall of the pressure plate 22 is made of rubber material, which can provide sufficient friction during the pressing process and avoid damage to the steel box girder side plate. The inner side walls on both sides of the steel frame 4 are provided with inner grooves 41, and movable plates 43 are installed in the inner grooves 41. The bottom of the movable plate 43 is supported by a number of springs 42 arranged at equal intervals. When the steel frame 4 slides to the appropriate position on the column 5, the spring 42 will apply pressure to the movable plate 43, so that a certain friction force is generated between the movable plate 43 and the outer wall of the column 5, thereby maintaining the stable positioning of the steel frame 4. After the welding of the steel box girder side plate is completed, the bolts 2 are loosened in time, and the positioning device is removed from the column 5 to carry out the construction of the next steel box girder side plate. The use of a fixing and deviation correction device for welding the steel box girder side plate can ensure the linearity and size during the welding process, achieving an economical, safe and efficient effect.

[0031] During the entire welding process, the device can effectively fix the steel box girder side plate to prevent it from shifting due to the high temperature and stress generated by welding. At the same time, the steel box girder side plates of different heights and sizes can be fixed through simple operations, greatly improving the welding accuracy and efficiency.

[0032] When the side plate welding of the steel box girder is corrected by using a jack or a welding triangular bracket, the size and linearity cannot be accurately controlled, the correction effect is poor, and there is a risk of the jack or the welding triangular bracket falling off, which is time-consuming and laborious. The use of a fixing and correcting device for welding the side plate of the steel box girder has a high material recycling rate, and almost no waste is generated during the process, which greatly saves costs. At the same time, it can be flexibly adjusted according to the size of different types of steel box girders, further improving the material turnover recycling rate. Therefore, when the fixing and correcting device for welding the side plate of the steel box girder is used for correction, it has good economic benefits. Nuts, bolts, steel side plates, steel frames and columns can all be recycled, and almost no damage occurs during the process. Even if damage occurs during the construction process, it can be processed and reused or used for other purposes, which will not cause pollution to the environment and has good environmental benefits. The use of a fixing and correcting device for welding the side plate of the steel box girder has the advantages of fast construction speed and high material recycling rate. The construction period and cost are guaranteed to a certain extent, and it has good social benefits.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
