In addition, the connection mode between the first end plate 22, the second end plate 23, and the two second rigid plates 21 can be welding, riveting, or other fasteners for connection, and is not limited to bolt connection. Figure 11As shown, the second rigid plate 21 has a first hinged end 211 (also referred to as a hinged support) for connection, which is rotatably connected to the other end of the arc-shaped plate 71 by a bolt.

[0070] In the embodiment, as shown, Figure 9 The arc-shaped angle brace 7 can include the arc-shaped plate 71 and the buckling-restrained component.

[0071] One end of the arc-shaped plate 71 is rotatably connected to the energy-consuming beam 31, and the other end is rotatably connected to the second bending-resistant beam 2, for example, the other end of the arc-shaped angle brace 7 is hinged to the node plate (i.e., the second rigid plate 21). When the arc-shaped plate is stressed, the buckling-restrained component can restrain the out-of-plane deformation of the arc-shaped plate.

[0072] The buckling-restrained component can include a first buckling-restrained plate 72 and a second buckling-restrained plate 73. The first and second buckling-restrained plates are respectively located on both sides of the arc-shaped plate 71, and form a space matching the thickness and deformation mode of the arc-shaped plate 71 between them.

[0073] The arc-shaped angle brace can further include a fixing member for fixing the first and second buckling-restrained plates.

[0074] The first buckling-restrained plate 72 can be provided with a groove matching the thickness and deformation mode of the arc-shaped plate 71; and the second buckling-restrained plate 73 is a flat plate and can cover the groove of the first buckling-restrained plate. Of course, the present application is not limited thereto, and the first and second buckling-restrained plates can both be provided with grooves, and the grooves of the two can form a space matching the thickness and deformation mode of the arc-shaped plate 71.

[0075] Further, the first and second buckling-restrained plates are both arc-shaped plates, and the arc length sides of the two are provided with bolt hole positions distributed along the arc length and corresponding one by one.

[0076] Further, the fixing member includes a plurality of bolts, the number of which is the same as and corresponds to the number of bolt hole positions on the buckling-restrained plates.

[0077] Further, the two ends of the arc-shaped plate 71 can be provided with a first bolt hole 711 and a second bolt hole 712 for connection.

[0078] The energy-consuming process of the tower energy-consuming support device under seismic load will be described in detail as follows:

[0079] When the tower structure and the tower energy dissipation support device are subjected to seismic load, the first rigid plate 11 can rotate around the hinge support 5 and the lug plate 41, and the energy dissipation assembly 3 is simultaneously subjected to the load from the first bending-resistant beam 1 and the second bending-resistant beam 2 at the upper and lower ends. The energy dissipation beam 31 first slides relative to the limiting plate 32, that is, the lower end of the energy dissipation beam 31 slides in the length range of the long circular hole until the lower end of the energy dissipation beam 31 slides to one end of the long circular hole. At this time, if the load continues to increase, the relative sliding between the energy dissipation beam 31 and the limiting plate 32 cannot completely offset the load. Since the energy dissipation beam 31 is a deformable member, the energy dissipation beam 31 is compressed and bent by the supporting reaction force of the hinge support 5 to further offset the load. During the entire load process, the first bending-resistant beam 1, the second bending-resistant beam 2 and the connecting column 4 almost do not bend and deform. The load on the entire tower structure can be basically completely offset by the relative sliding and bending of the energy dissipation assembly 3, so that the original structure of the tower can remain stable in the seismic load and is protected from being damaged. Since the buckling-restrained assembly limits the deformation of the arc-shaped angle support out of the plane and also limits the deformation of the energy dissipation beam 31, the performance of the entire energy dissipation support device is greatly improved, and multi-stage energy dissipation is achieved.

[0080] Example 2

[0081] The present example provides a tower energy dissipation support device located in the middle of a tower structure.

[0082] Figure 8 The overall structure of the tower energy dissipation support device of the present example is shown in FIG. 2, Figure 12 The structural deformation of the tower energy dissipation support device of the present example is shown in FIG. 3.

[0083] As shown in FIG. 1, Figure 8 and Figure 12 The tower energy dissipation support device of the present example is arranged in the middle of the tower structure, and its overall structure is basically the same as that of the tower energy dissipation support device arranged at the top of the tower structure in Example 1. The first bending-resistant beam 1 is arranged in parallel with the tower beam above it and can form a double-layer truss structure with the tower beam. One end of the first bending-resistant beam 1 is bolted to the hinge support 5, and the other end is bolted to the lug plate 41 welded to the outer wall of the connecting column 4. Figure 7(As shown) the first bending beam 1 is hinged with bolts, but the invention is not limited to this. One end of the first bending beam 1 can also be hinged to the hinge support 5 through a pin or other connecting parts, or the first bending beam 1 can also be directly connected to the tower, as long as the first bending beam 1 can rotate freely around its connection point with the tower; the other end of the first bending beam 1 can also be hinged to the ear plate 41 through a pin or other connecting parts, or the first bending beam 1 can also be directly connected to the connecting column 4, as long as the first bending beam 1 can rotate freely around its connection point with the connecting column 4; the ear plate 41 can also be installed on the outer wall of the connecting column 4 by integral molding, screw connection or other connection methods.

[0084] Furthermore, a retaining ring 6 is installed at the upper and lower ends of the connection between the ear plate 41 and the connecting post 4. The retaining ring 6 is sleeved on the outside of the connecting post 4, and the upper and lower end faces of the ear plate 41 abut against the end faces of the retaining rings 6 on its upper and lower sides, respectively. Installing the retaining rings 6 can strengthen the connection between the ear plate 41 and the connecting post 4, ensuring that the connection between the ear plate 41 and the connecting post 4 meets the strength requirements. In this embodiment, the number of retaining rings 6 is 4, but the present invention is not limited to this, and the number of retaining rings 6 can also be other positive integers other than 4.

[0085] Except for the structural features described above which differ from those in Exemplary Example 1, all other structural features and the energy dissipation process under seismic loads are the same as in Exemplary Example 1. Therefore, the structural features and energy dissipation processes that are the same as those in Exemplary Example 1 will not be described again in this exemplary embodiment.

[0086] Exemplary Example 3

[0087] This exemplary embodiment provides an application of a tower energy-dissipating support device in energy dissipation and vibration reduction.

[0088] like Figure 12 As shown in the illustration, the tower energy dissipation support device located at the top of the tower structure in Exemplary Embodiment 1 is located at point A, and the tower energy dissipation support device located in the middle of the tower structure in Exemplary Embodiment 2 is located at point B. When the tower is subjected to lateral loads caused by an earthquake, the entire structure deforms, and the structural deformation at points A and B is as follows: Figure 12 As can be seen, the energy-dissipating components in the tower's energy-dissipating support device can undergo bending deformation after being subjected to load. At the same time, the lower end of the energy-dissipating beam can slide relative to the limiting plate, thereby jointly dissipating energy to offset the load. During the load process, the first bending beam, the second bending beam, and the connecting column hardly undergo bending deformation. The load on the entire tower structure can be basically completely offset by the relative sliding and bending that occur in the energy-dissipating components. Therefore, the original tower structure can remain stable under seismic loads and be protected from damage.

[0092] In summary, the tower energy dissipation support device in the present application is configured with a high-rise tower support of T-shaped energy dissipation section, which has good energy dissipation capacity.The T-shaped energy dissipation assembly can be easily replaced, and efficient post-earthquake repair is facilitated, solving the technical problem of complex and high-cost repair work caused by structural damage, greatly improving the seismic performance and service life of new energy support structure.
