[0023] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The steel structure single-story industrial plant roof lifting construction adopts the method of adding new columns on the original structural columns, and using a lifting device to vertically lift the steel structure single-story industrial plant roof without dismantling the steel structure single-story industrial plant roof frame. Based on this construction method, the light solid web composite column 1 can be used as a new column to bear the roof load, and has the advantages of good mechanical properties, saving steel, light weight, and guaranteed quality of factory prefabrication.

[0025] See attached Figure 1-5 A light solid composite column for the roof of a steel structure single-story industrial plant, fixed on an existing structural column 2 by welding, includes a channel steel 3, a web 4, a connecting plate 5 and a stiffening plate 6, the web 4 is connected to the channel steel 3 on both sides, and the stiffening plate 6 is fixed at the beam-column connection node and on both sides of the web, and is used to strengthen the rigidity of the light solid composite column 1 to ensure local stability. A connecting plate 5 is fixed on the outside of the channel steel 3, and the connecting plate 5 is used to connect the steel structure roof truss 8. The connecting plate 5 is used as a connecting member between the light solid composite column 1 and the steel structure single-story industrial plant roof truss, and is fixed to the roof truss by welding and high-strength bolt connection.

[0026] The arc-starting plate 7 is also included, and the arc-starting plate 7 is arranged outside the channel steel 3. The arc-starting plate 7 and the steel structure roof truss 8 are fixed by full penetration welding. The arc-starting plate 7 is used to avoid the formation of concave welds at the starting point and end point of the weld due to inability to penetrate, and the formation of cracks and stress concentration after being subjected to force.

[0027] The materials of the channel steel 3, the web 4, the connecting plate 5, the stiffening plate 6 and the arc-starting plate 7 can all be ordinary steel or high-quality steel.

[0028] The web 4 is a flat steel plate, the channel steel 3 is U-shaped, and the center of the channel steel 3 is fixed to the end of the web 4 .

[0029] The connecting plate 5 is rectangular.

[0030] The channel steel 3 is welded and fixed to the web plate 4, the connecting plate 5, and the stiffening plate 6, and the channel steel 3 is welded and fixed to the arc-starting plate 7, and all are welded and prefabricated in the factory to improve the finished product quality and mechanical properties of the light solid composite column 1. The finished composite column prefabricated in the factory can be directly used for on-site installation.

[0031] As a structural column in the steel structure single-story industrial plant roof lifting construction, the light solid composite column 1 bears the roof load, making full use of the existing structure of the steel structure single-story industrial plant, and is installed on the existing structural column 2 of the steel structure single-story industrial plant. In the steel structure single-story industrial plant roof lifting construction, the light solid composite column 1 is used as the structural column of the lifting part, and is fixed to the existing structural column of the steel structure single-story industrial plant by welding. Before installing the light solid composite column 1, the connection part of the original structural column is cleaned, leveled, and polished so that the connection interface can be tightly connected, and then the assembly gap is processed with a groove to ensure that the entire thickness of the weldment is fully penetrated during the welding process to form a firm joint.
