Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bridge engineering, and in particular relates to a steel shell tower wall plate welding tool. Background Art
[0002] To meet the needs of an increasingly comprehensive and expanding transportation network, the use of steel-shell tower bridges is gradually expanding in the unique geographical conditions of the hilly southwest, such as those found in the region. Steel-shell towers are designed as thin-walled, U-shaped steel towers. While traditional steel-shell tower panels are thick and rigid, new thin-wall designs are becoming the industry's preferred approach. However, these panels present high demands in terms of fabrication, assembly and welding deformation control, and precision management. Improving panel processing accuracy and producing high-quality panels that meet both design precision and aesthetic requirements are pressing challenges.
[0003] At present, the interior of the steel tower wall is Figure 1 As shown in the figure, its main features are: (1) 10mm PBL shear key stiffeners are densely arranged in the horizontal and vertical directions on one side of the wall panel, and the stiffeners are assembled into a lattice frame shape; (2) The wall panel is only 10mm thick. The difficulties in its production are: (1) Due to the large number of longitudinal and transverse stiffeners, the longitudinal seams, transverse seams, and vertical seams are densely distributed after assembly, resulting in large deformation after welding and difficulty in adjustment; (2) The wall panel is relatively thin, with a thickness of only 10mm, and 10mm thick PBL shear key stiffeners are densely arranged in the horizontal and vertical directions of the wall panel, making it difficult to control the flatness after welding. In order to solve the above problems, a wall panel welding platform with high levelness, favorable heat dissipation during welding, flexible size assembly, easy disassembly, easy transportation, and low cost is required when welding the wall panel. Summary of the Invention
[0004] The purpose of the present invention is to solve the above-mentioned problems and to propose a welding tool for steel shell tower wall panels. The use of the welding tool of the present invention can effectively solve the problems of difficult deformation control and flatness control in wall panel production, and realize high-precision production of steel shell tower wall panels.

[0006] Furthermore, longitudinal beams are provided between the transverse beams, the upper surfaces of the longitudinal beams are flush with the upper surfaces of the transverse beams, and the longitudinal beams are also provided with supporting stiffening ribs and height measurement points.
[0007] Furthermore, the supporting stiffening rib is fixed on the upper surface of the beam.
[0008] Furthermore, the upper end of the column is connected to the lower side of the beam through a seat plate.
[0009] Furthermore, the crossbeam and the column are I-beams.
[0010] Furthermore, a U-shaped clamp is provided, one side of the U-shaped clamp is clamped on the wall panel to be welded, and the other side is clamped on the crossbeam, so as to fix the wall panel to be welded on the crossbeam.
[0011] Compared with the existing technology, the outstanding effects of the present invention are: ① The height measurement points and supporting stiffening ribs on the welding fixture can achieve high-precision production and flatness control of the wall panels; ② The welding fixture is flexible in size assembly and can quickly adapt to the production of wall panels of different sizes; ③ The bottom of the welding fixture is conducive to heat dissipation, which can improve welding deformation and improve welding efficiency; ④ The welding fixture is easy to disassemble and can be recycled, which reduces production costs and conforms to the concept of green manufacturing.

[0017] The embodiments of the present invention are further described below with reference to the accompanying drawings.
[0018] like Figure 2 As shown, the embodiment of the welding fixture of the present invention consists of three horizontal beams 1 and four longitudinal beams 5. Twelve vertical columns 1 are connected downwardly at the intersection of each horizontal beam 1 and longitudinal beam 5. The columns 1 are connected to pre-buried steel plates in the ground. To facilitate connection, a seat plate 6 is provided between the columns 2 and the horizontal beams 1. All connection methods are common to bolt welding, with bolt connection being preferred.
[0019] like Figure 3 As shown, in the assembled welding fixture, horizontal (h1, h2, ..., h12) and vertical (s1, s2, ..., s8) height measurement points 4 are arranged on the crossbeam 1 and longitudinal beam 5. The height of the support stiffener 3 is precisely machined based on the levels of the height measurement points 4, ensuring that the horizontal height of the upper edge of the support stiffener 3 is consistent at all locations. The support stiffener 3 is spot welded to the crossbeam 1 and longitudinal beam 5.
[0020] When manufacturing the steel tower wall panels, the steel plates to be welded are fixed to the crossbeam 1 from all sides using U-shaped brackets 7. The vertical PBL shear key stiffeners are assembled first, followed by the transverse PBL shear keys. Welding is done from the center outward, from the inside out, to ensure the flatness of the wall panels. The welds between the horizontal and vertical PBL shear key stiffeners and the underlying steel plates, as well as the intersection welds between the PBL shear key stiffeners, are welded from the center outward, from the inside out.
[0021] The utility model can also meet the flatness requirements of different wall panels by setting the number and spacing of the cross beams and the longitudinal beams.
