Description

Technical Field

[0001] The utility model relates to the technical field of tools for processing deformation of two edges of a steel box beam, in particular to an edge correction device for an upper panel of a steel box beam. Background Art

[0002] Steel box girder is a commonly used engineering construction material and an important bridge component. It is welded from steel plates and includes an upper panel and a lower panel arranged in parallel. Two webs arranged in parallel are welded between the upper panel and the lower panel. After the plates are welded together, the overall structure is similar to a rectangular box. When the steel box girder is used as an important component of a bridge, it bears the main load of the bridge and is responsible for transferring the load on the bridge deck to the piers. It has high strength and stability and can effectively share and transfer loads. Therefore, it is widely used in bridge construction, and the manufacturing quality is particularly important. Generally, after the steel box girder is manufactured, it needs to be corrected to ensure the accuracy of its structure and geometry, such as eliminating the deformation of the two edges of the upper panel during the manufacturing process.

[0003] The design grade of the web and panel weld is a full penetration first-level weld, and the upper panel exceeds the web by about 100mm on both sides. Since welding will produce very obvious shrinkage stress, it is easy to cause different degrees of collapse and deformation on both edges of the upper panel. In order to ensure the processing quality of the steel box girder, the above phenomenon needs to be corrected. The traditional correction method is mainly achieved by using artificial flames and external forces applied by the correction machine. The correction machine used is large in size and inconvenient for position adjustment. It is not flexible to use and adjust the upper panels of different widths, and the correction operation is cumbersome, resulting in low correction efficiency. Utility Model Content

[0006] As a preferred technical solution, the correction lifting card plate includes a correction lifting vertical plate, through which a beam through-hole for assembling the correction beam is provided, and the bottom end of the correction lifting vertical plate is fixedly connected with a correction lifting horizontal plate, and the correction lifting horizontal plate extends inwardly and is arranged vertically with the correction lifting vertical plate.

[0007] As a preferred technical solution, two clamping plate limiting grooves are relatively provided at the top end of the correction beam, and the two clamping plate limiting grooves are both located on the outer side of the upper panel of the steel box beam.

DETAILED DESCRIPTION

[0016] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, the edge correction device of the upper panel of the steel box beam is used to lift and correct the collapsed position of the edge of the upper panel 1 of the steel box beam. Specifically, it includes a correction beam 2 spanning directly above the upper panel 1 of the steel box beam, and at least two beam moving rollers 3 are arranged and installed at the bottom end of the correction beam 2. The beam moving rollers 3 are against the top of the upper panel 1 of the steel box beam, and can easily drive the entire device to move along the upper panel 1 of the steel box beam to adjust the correction position. It is easy to use and labor-saving, and no accessories need to be disassembled or assembled during the movement, which helps to improve the correction efficiency.

[0018] The bottom end of the correction beam 2 is relatively fixedly mounted with at least two beam lifting devices, and the two ends of the correction beam 2 are detachably mounted with correction lifting plates 4, and the lower end of the correction lifting plates 4 is limited against the bottom end of the edge of the corresponding side of the upper panel 1 of the steel box beam. The correction beam 2 can be lifted up by the beam lifting device, and under the assembly of the correction beam 2 and the correction lifting plates 4, the correction lifting plates 4 will move up synchronously, thereby driving the edge of the upper panel 1 of the steel box beam that forms a limit thereto to be lifted up, thereby completing the correction of the edge collapse of the upper panel 1 of the steel box beam.

[0019] Among them, the correction lifting card plate 4 includes a correction lifting vertical plate 41, and a beam through-hole for assembling the correction beam 2 is provided through the correction lifting vertical plate 41. The correction beam 2 can be detachably assembled with the correction lifting vertical plate 41 through the beam through-hole. The two have a large contact area and a large force strength, and do not require the aid of other accessories and tools, so the disassembly and assembly are simple and convenient. The bottom end of the correction lifting vertical plate 41 is fixedly connected with a correction lifting horizontal plate 42, and the correction lifting horizontal plate 42 extends inward and is arranged vertically with the correction lifting vertical plate 41. The correction lifting vertical plate 41 and the correction lifting horizontal plate 42 are arranged in an L shape. The correction lifting horizontal plate 42 can be an integrated flange structure at the bottom end of the correction lifting vertical plate 41, so that the processing technology is simple.

[0020] Two card plate limit grooves 25 are arranged opposite to each other at the top of the correction beam 2, and both of the card plate limit grooves 25 are located on the outside of the upper panel 1 of the steel box beam, and the correction lifting plate 41 is limitedly assembled in the corresponding card plate limit grooves 25. When the correction beam 2 is lifted by the beam lifting device, the synchronous lifting of the correction lifting plate 41 forms a horizontal limit to improve the stability of the assembly of the two during correction, which helps to ensure the smooth implementation of the correction task. The beam lifting device is set as a jack 5, which is simple to operate and easy to install.

[0021] like Figure 3 As shown, the correction beam 2 includes a beam body 21, and recessed beam insertion grooves 22 are respectively provided at both ends of the beam body 21. The two ends of the beam body 21 are also respectively provided with beam splits 23. Each beam split 23 is provided with a beam plug-in body 24 on one side facing the beam body 21. The beam plug-in body 24 and the corresponding beam insertion groove 22 can be detachably plugged and matched. The clamping plate limiting groove 25 is provided at the top of the beam split 23 on the corresponding side. Through the cooperation between the beam body 21 and the beam split 23, the width of the correction beam 2 can be adjusted to a certain extent to meet the correction of the two edges of the upper panel 1 of the steel box beam with different widths, so as to improve the versatility of this embodiment, and the adjustment is simple and convenient.
