[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] refer to Figures 1 to 5 ,like Figure 1 As shown, this embodiment provides a lightweight truss structure, which mainly consists of a bottom truss structure 1, a standard truss structure 2, a heightening section structure 3, and a bottom support assembly 4. The standard truss structure 2 is connected to the bottom truss structure 1, the heightening section structure 3 is connected to the standard truss structure 2, and the bottom support assembly 4 is installed on the bottom truss structure 1.

[0024] The bottom truss structure 1 mainly consists of several first main frames 11, a first base frame 12, a first upper frame 16, and several side supports. The first main frames 11 are distributed in parallel at intervals, with their lengths increasing sequentially, so that the first upper frame 16 can be inclinedly connected to the upper ends of the first main frames 11. The first base frame 12 is vertically connected to the bottom of the first main frames 11, giving the bottom truss structure 1 an overall right-angled trapezoidal shape. To enhance the reliability of the connections, first ribs 111 are provided between the first main frame 11 and the first base frame 12, and between the first main frame 11 and the first upper frame 16. Furthermore, at the end of the first upper frame 16 furthest from the standard truss structure 2 ( Figure 1 The upper right end of the plate is provided with a second rib 15, and a threaded pipe 151 is fixedly installed on it. The threaded pipe 151 is used to connect the base support assembly 4.

[0025] To further enhance the connection reliability between the first main frame 11, the first base frame 12, and the first upper frame 16, a side support is provided, consisting of several first supports 13 and several second supports 131. The first supports 13 are inclinedly connected between the first upper frame 16 and the first main frame 11, and the second supports 131 are inclinedly connected between the first main frame 11 and the first base frame 12, with opposite inclination directions. This effectively distributes the load among the first main frame 11, the first base frame 12, and the first upper frame 16, improving support strength. The connection point of the first supports 13 / second supports 131 avoids the position of the first rib 111; that is, when the connection point of the first supports 13 / second supports 131 is higher, the first rib 111 is lower, and when the connection point of the first supports 13 / second supports 131 is lower, the first rib 111 is higher.

[0026] Preferably, an auxiliary support 132 is connected between the rightmost second support 131 and the rightmost first main frame 11, so that the second support 131, the first main frame 11 and the first base frame 12 form a triangular structure to improve the connection stability.

[0027] Several channel steel lugs 122 are provided on the sides of the first base frame 12, the second base frame 24, and the third base frame 33 for connecting external stabilizing cables or additional components. Several pads 17 are provided on the first upper frame 16 to increase the contact area, distribute the load, or provide an installation platform.

[0028] During assembly, the first base frame 12, the second base frame 24, and the third base frame 33 are sequentially connected to each other via two sets of connecting plates 121. Similarly, the first upper frame 16, the second upper frame 21, and the third upper frame 34 are also sequentially connected to each other via connecting plates 121. Each set of connecting plates 121 is connected by bolts and locked with nuts. If necessary, flat washers, spring washers, or other gasket structures can be added to the nut side or the bolt head to enhance the reliability of the connection.

[0029] like Figure 2 As shown, the standard truss structure 2 mainly consists of several second main frames 22, a second base frame 24, and a second upper frame 21. The several second main frames 22 are distributed parallel to the left side of the first main frame 11. The second base frame 24 is vertically connected to the lower end of the several second main frames 22, and the second upper frame 21 is vertically connected to the upper end of the several second main frames 22. To enhance the strength of the joints, first ribs 111 are provided between the second main frames 22 and the second base frame 24, and between the second upper frame 21 and the second main frames 22. Several ear plates 211 are provided on the second upper frame 21. A pair of oppositely distributed third supports 23 are provided between the second base frame 24 and the second upper frame 21. The arrangement of the first ribs 111 and the third supports 23 avoids each other, that is, if the connection point of the third support 23 is higher, the first ribs 111 is lower, and vice versa.

[0030] like Figure 3 As shown, the heightening section structure 3 mainly consists of a third main frame 31, a third base frame 33, a fourth support 32, and a third upper frame 34. The third upper frame 34 and the third base frame 33 are vertically connected to the upper and lower ends of the third main frame 31, respectively. The fourth support 32 is inclinedly connected between the third main frame 31 and the third base frame 33, serving to support the third main frame 31 and the third base frame 33, enhance the connection rigidity between them, and improve the overall support strength.

[0031] like Figure 4 As shown, the base support assembly 4 is mainly composed of a screw 41, a nut 42, a base plate 44, and an angle steel 43. The screw 41 is inserted into the threaded tube 151, the nut 42 is screwed onto one end of the screw 41, the base plate 44 is connected to the other end of the screw 41, and the angle steel 43 is connected between the base plate 44 and the screw 41 to provide reinforcement.

[0032] In this embodiment, the first main frame 11, the first base frame 12, the first support 13, the second support 131, the auxiliary support 132, the first upper frame 16, the second upper frame 21, the second main frame 22, the third support 23, the second base frame 24, the third main frame 31, the fourth support 32, the third base frame 33, and the third upper frame 34 all adopt a rectangular hollow tube structure to achieve lightweighting while ensuring strength.
