[0002] With the rapid development of science and technology, there are more and more large-scale special-shaped buildings and structures, and various welding, hoisting and assembly methods for special-shaped components are constantly emerging. In the field of LED electronic display screens, various innovative display screens are constantly being designed, which not only add a sense of technology and modernity to various large and high-end buildings, but also play a certain role in establishing the image of the building; but the problem that comes with it is that the steel frame of the screen is getting bigger and bigger, and the shape is getting more and more peculiar, making the welding and hoisting of the steel frame more and more difficult, and the stability of the steel frame is difficult to ensure during the hoisting of the whole steel frame, and there are hidden dangers in the hoisting safety; how to realize the welding and hoisting of large special-shaped screen steel frames more simply and labor-savingly has become a problem to be solved. Based on this, the utility model designs a new type of riveting device for large special-shaped components. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a riveting device for large special-shaped components, which solves the problems of difficulty in ensuring stability, low safety, and difficult construction in the overall hoisting of traditional steel frames.

[0004] The utility model achieves the above technical purpose through the following technical means.

[0005] A riveting device for large special-shaped components, which is composed of multiple sub-components assembled by the riveting device. The riveting device includes an L-shaped customized bending piece and a chrysanthemum-shaped locking bending piece fixed on the sub-components. One end of the L-shaped customized bending piece extends out of the sub-component and is provided with a screw mounting hole. A welding nut for tightening the screw is welded and fixed at the screw mounting hole. The chrysanthemum-shaped locking bending piece is also provided with a screw mounting hole. The L-shaped customized bending piece and the chrysanthemum-shaped locking bending piece on adjacent sub-components are fixed by a screw with a limiter.

[0006] Furthermore, the sub-components, L-shaped custom bent parts, and daisy-shaped locking bent parts of the large special-shaped component are all provided with positioning column mounting holes for installing welding positioning columns, and the welding positioning columns are passed through the positioning column mounting holes and then welded and fixed.

[0007] Furthermore, the L-shaped customized bent part is formed by bending a stainless steel plate with a length of 160 mm, a height of 40 mm and a thickness of 2 mm.

[0008] Furthermore, the daisy-shaped locking bending piece is formed by cutting and bending a 2 mm thick stainless steel plate.

[0009] Furthermore, the welding positioning column is a stainless steel rod with a diameter of 6 mm.

[0010] The utility model has the following beneficial effects:

[0011] The utility model divides the entire screen steel frame into several groups, each group is assembled and docked separately, and a segmented connection device (i.e., an L-shaped customized bending piece and a daisy-shaped locking bending piece) is reserved at the docking edge of each group. Since the special-shaped components are heavy and large in size, such grouping is conducive to welding and reduces the potential safety hazards of hoisting caused by excessively large components. When docking, each component can be assembled and assembled into place by screwing the screw to form a complete whole, which is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS
