[0019] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0020] In the description of this application, the term "for example" is used to mean "used as an example, illustration, or description." Any embodiment described as "for example" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0021] Example 1 See Figure 1 , Figure 2 This embodiment provides a lattice steel column, including a base 1, a lower section 2, a middle section 3, an upper section 4, and a connecting component 5; the base 1, the lower section 2, the middle section 3, and the upper section 4 are arranged sequentially from bottom to top, and the lower section 2 and the middle section 3, as well as the middle section 3 and the lower section 2, are connected by the connecting component 5; the longitudinal section structure formed by the base 1, the lower section 2, the middle section 3, and the upper section 4 is trapezoidal, and the cross-section of the top of the upper section 4 is smaller than the cross-section of the base 1.

[0022] For example, the base 1 includes four connecting rods 11, four base plates 12, and several second reinforcing plates 13. The four base plates 12 are connected by the four connecting rods 11, so that the four connecting rods 11 and the four base plates 12 form a quadrilateral, and each base plate 12 is provided with several second reinforcing plates 13 to improve the stability of the lower section 2.

[0023] This embodiment adopts a segmented structure, which is convenient to purchase and transport, and can be installed on site without the need for large-tonnage special equipment. It is also convenient to disassemble and maintain.

It should be noted that the nodes here are the nodes where adjacent sections of the first main steel bars 21 are welded together. The first connecting plate 23 is set at this point to improve the stability of the node; for example, the first connecting plate 23 can be a rhombus plate, the transverse center line of the rhombus plate corresponds to the node, and the rhombus plate is welded to the outer wall of the first main steel bar 21 at the node.

[0025] It should be noted that the lower parts of the four first main steel bars 21 correspond to the four base plates 12 respectively. One vertical surface of the second reinforcing plate 13 is fixed to the upper surface of the base plate 12, and the other vertical surface of the second reinforcing plate 13 is fixed to the corresponding first main steel bar 21. This avoids loosening of the joints, saves materials, and improves the stability of the structure.

[0027] For example, the first connecting steel 24 and the second connecting steel 25 are arranged crosswise in space, and the two ends of the first connecting steel 24 and the two ends of the second connecting steel 25 are respectively welded to the inner sidewalls of the four first main steels 21 in the lower section 2, so as to improve the overall load-bearing stability of the steel column and enhance the steel column's resistance to lateral displacement and torsion.

[0028] The steel column model can be marked on the first sign 26 to facilitate identification during installation and maintenance.

[0029] Furthermore, the lower section 2 also includes a first crossbar 27.

A first crossbar 27 is provided between adjacent two first diagonal steel bars 22. The first crossbar 27 is located above the first connecting plate 23. Through the design of the first crossbar 27 combined with the first diagonal steel bars 22, the stability and load-bearing strength of the first main steel bars 21 in the lower section 2 are improved.

[0036] See Figure 1 , Figure 2 , Figure 4 It should be noted that the column top component 6 includes two guy angle steels 61, two U-shaped angle steels 62, and a reinforcing steel 63. The two guy angle steels 61 are arranged in parallel, and their common ends are connected by a U-shaped angle steel 62, so that the guy angle steels 61 and the U-shaped angle steels 62 form a quadrilateral. The four corners of this quadrilateral are welded to the inside of the third main steel 41, and the reinforcing steel 63 divides the quadrilateral in two. For example, the guy angle steels 61 are provided with anchor holes 611 for easy installation of electrical equipment.

[0037] It should be noted that the first connecting steel 24 and the second connecting steel 25 are provided in a cross arrangement above the second connecting plate 34 in the middle section 3 and above the third connecting plate 44 in the upper section 4, in order to enhance the stability of the welded joints in the middle section 3 and the upper section 4, thereby improving the strength of the steel column.

This structural design improves the stability of the connection between the middle section 3 and the lower section 2.

[0041] It should be noted that, as needed, the first crossbar 27 may also be provided in the middle section 3 and the upper section 4, and the method of setting it is the same as that of setting it in the lower section 2.
