The connector has an "L" shaped cross-section. Symmetrically arranged connectors are provided on both sides of the second web. The connector includes a first connecting plate and a second connecting plate. The first connecting plate contacts the second web. The first connecting plate has a second waist-shaped hole corresponding to the first waist-shaped hole. The second waist-shaped hole and the first waist-shaped hole are arranged in an "X" shape. The first locking bolt passes through the second waist-shaped hole and the first waist-shaped hole. The second connecting plate contacts the first web. The second connecting plate has a fourth waist-shaped hole corresponding to the third waist-shaped hole. The fourth waist-shaped hole and the third waist-shaped hole are arranged in an "X" shape. The second locking bolt passes through the fourth waist-shaped hole and the third waist-shaped hole.

[0007] As a further description of the above technical solution: The second connecting plate has a bent edge at its end, and the end of the bent edge contacts the flange of the I-beam.

[0008] As a further description of the above technical solution: The first synchronous plate is provided with several first through holes arranged along its own length direction. The first synchronous plate is arranged along the length direction of the T-shaped steel. The first synchronous plate contacts the first connecting plate. The screw of the first locking bolt passes through the first connecting plate.

[0009] As a further description of the above technical solution: The first synchronization plate includes several first synchronization plate units, which are arranged sequentially along the length of the T-shaped steel. The ends of two adjacent first synchronization plate units overlap to form a first overlapping part, and the first locking bolt passes through the first overlapping part.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0021] Please see Figure 1-5 This utility model provides a technical solution: a high-strength prefabricated irregular-shaped structural column, comprising: The I-beam 1 includes a first web 11, on which two rows of third waist-shaped holes 111 are symmetrically arranged, and each row of third waist-shaped holes 111 includes a plurality of third waist-shaped holes 111 arranged along the length direction of the first web 11. T-shaped steel 2 includes a second web plate, the bottom of which contacts the first web plate 11, and the second web plate is provided with a plurality of first waist-shaped holes 21 arranged along its own length direction. The connector 3 has an "L" shaped cross-section. The connector 3 is symmetrically arranged on both sides of the second web. The connector 3 includes a first connecting plate 31 and a second connecting plate 32. The first connecting plate 31 contacts the second web. The first connecting plate 31 has a second waist-shaped hole 311 corresponding to the first waist-shaped hole 21. The second waist-shaped hole 311 and the first waist-shaped hole 21 are arranged in an "X" shape. The first locking bolt 33 passes through the second waist-shaped hole 311 and the first waist-shaped hole 21. The second connecting plate 32 contacts the first web 11. The second connecting plate 32 has a fourth waist-shaped hole 321 corresponding to the third waist-shaped hole 111. The fourth waist-shaped hole 321 and the third waist-shaped hole 111 are arranged in an "X" shape. The second locking bolt 34 passes through the fourth waist-shaped hole 321 and the third waist-shaped hole 111.

[0022] The irregularly shaped structural column inside the wind turbine tower consists of two parts: an I-beam 1 and a T-beam 2. The webs of the I-beam 1 and the T-beam 2 are fixed together by a connector 3. The connector 3 is fixed to the T-beam 2 and the I-beam 1 by a first locking bolt 33 and a second locking bolt 34, respectively. This irregularly shaped structural column, through its prefabricated design, facilitates the disassembly and replacement of deformable parts. Furthermore, it effectively improves structural strength, enhances resistance to deformation, and improves the safety of the internal functional facilities of the wind turbine tower.

[0023] Working principle: The first locking bolt 33 on connector 3 passes through the second slotted hole 311 and the first slotted hole 21, allowing the distance between the bottom of the second web plate and the first web plate 11 on the I-beam 1 to be adjustable. The second locking bolt 34 passes through the fourth slotted hole 321 and the third slotted hole 111, allowing the I-beam 1 and the T-beam 2 to move and adjust their relative positions along their length, thus enabling flexible adjustment of the shape of the irregularly shaped column. See appendix. Figure 3-4 Taking the adjustment of the distance between the bottom of the second web plate and the first web plate 11 on the I-beam 1 as an example, since the second waist-shaped hole 311 on the connector 3 and the first waist-shaped hole 21 on the T-beam 2 are arranged in an "X" shape, when the second web plate of the T-beam 2 is far away from the first web plate 11, as long as there is an intersection point between the second waist-shaped hole 311 and the first waist-shaped hole 21, it can still be locked using the first locking bolt 33. Similarly, by using the "X" shape arrangement of the fourth waist-shaped hole 321 and the third waist-shaped hole 111, the relative positions of the I-beam 1 and the T-beam 2 can be adjusted in the length direction. Example 2

[0024] Based on the above embodiments, this embodiment further improves upon the following technical solution: the end of the second connecting plate 32 is provided with a bent edge 322, and the end of the bent edge 322 contacts the flange of the I-beam 1.

[0025] When fixing the I-beam 1 and the T-beam 2, the connecting pieces 3 on both sides of the T-beam 2 are first fixed to the second web plate. A first locking bolt 33 fixes the connecting pieces 3 on both sides of the second web plate. Then, the second web plate of the T-beam 2 and the connecting pieces 3 are inserted together between the two flanges of the I-beam 1. The setting of the bent edge 322 can prevent the connecting pieces 3 from colliding and being damaged with the flanges of the I-beam 1. Example 3

[0026] This embodiment further improves upon the above embodiment by providing the following technical solution: The first synchronous plate 4 has several first through holes arranged along its own length. The first synchronous plate 4 is arranged along the length of the T-shaped steel 2 and contacts the first connecting plate 31. The thread of the first locking bolt 33 passes through the first connecting plate 31. When the connector 3 is installed, several first locking bolts 33 are positioned within the first through holes of the first connecting plate 31, allowing the spacing of several connectors 3 on one side of the T-shaped steel 2 to be controlled by the first synchronous plate 4, facilitating the installation of the connectors 3.

[0027] Preferably, the first synchronization plate 4 includes a plurality of first synchronization plate units 41, which are arranged sequentially along the length of the T-steel 2. The ends of two adjacent first synchronization plate units 41 overlap to form a first overlapping part, and the first locking bolt 33 passes through the first overlapping part.

[0028] A long, narrow first synchronization plate 4 is optimized into several short first synchronization plate units 41. The ends of two adjacent first synchronization plate units 41 overlap to form a first overlapping portion, and the first through holes of two adjacent first synchronization plate units 41 at the first overlapping portion correspond, so that the first locking bolt 33 passes through the first overlapping portion, thereby fixing two adjacent first synchronization plate units 41. Shortening the length of a single first synchronization plate 4 solves the problem of easy deformation of the long, thin plate structure of the first synchronization plate 4. At the same time, it facilitates disassembly and installation during later maintenance of irregularly shaped structural columns, reducing maintenance costs. Example 4

[0029] This embodiment further improves upon the above embodiment by providing the following technical solution: The second synchronization plate 5 is provided with several second through holes arranged along its own length. The second synchronization plate 5 is arranged along the length of the I-beam 1, and the second synchronization plate 5 contacts the second connecting plate 32. The screw of the second locking bolt 34 passes through the second connecting plate 32, and the screw of the second locking bolt 34 is located within the second through holes. The second synchronization plate 5 is a steel plate.

[0030] The second synchronous plate 5 improves the deformation resistance of the first web plate 11 and enhances the strength of the irregular structural column.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
