Technical Field

[0001] The present invention relates to the technical field of structural earthquake resistance, and in particular to an energy-absorbing earthquake-resistant tower structure, a tower energy-absorbing support device and applications thereof. Background Art

[0002] With the limited nature of conventional energy and increasingly prominent environmental problems, how to better achieve the high-quality development of my country's new energy buildings has become a key issue. Cantilever structures are commonly used in new energy building structures. Although they have long been widely used in my country, such as transmission towers, wind power towers, solar thermal towers and other energy buildings, truss support structures with many advantages such as small footprint, high rigidity and high degree of assembly are used more. For example, the Chinese utility model patent with the publication number "CN202732240U" discloses a wind power tower structure, including a platform, the upper end of the platform is connected to the tower, the lower end of the platform is connected to the tower, and the upper end face or lower end face of the platform is provided with a support column, and a plurality of diagonal bracing connecting rods are connected to the support column, and the other end of the diagonal bracing connecting rod is connected to the tower or tower. The patent discloses a transition section structure connected between the tower and the tower, and a support column is provided on the upper and lower parts of the support seat, and the other end of the support column is connected to the tower or tower. This structure is a typical truss structure, but if it is used in a strong earthquake zone, when it is subjected to destructive lateral loads caused by the seismic shear waves of the strong earthquake, since it does not have an earthquake-resistant structure, all the loads will be concentrated in the tower structure, which puts high demands on the performance of the tower material. After the earthquake, it will greatly affect the service life of the tower and bring more safety hazards. Therefore, based on the above technical problems, it is urgently necessary to propose a new tower earthquake-resistant structure to replace the tower structure to achieve the role of energy dissipation and shock reduction.

During the loading process, the first anti-bending beam, the second anti-bending beam and the connecting column hardly undergo bending deformation, and the load on the entire tower structure can be basically offset by the relative sliding and bending occurring in the energy-absorbing component; because the buckling restraint component limits the deformation outside the plane of the arc-shaped angle brace to the maximum extent and restrains the deformation of the energy-absorbing beam at the same time, the performance of the entire energy-absorbing support device is greatly improved, and multi-stage energy consumption is achieved.

At the same time, the lower end of the energy-absorbing beam may slide relative to the limiting plate to jointly consume energy to offset the load. During the loading process, the first anti-bending beam, the second anti-bending beam and the connecting column hardly bend and deform. The load borne by the entire tower structure may be basically offset by the relative sliding and bending occurring in the energy-absorbing component. Therefore, the original structure of the tower may remain stable under earthquake loads and be protected from damage.

Although it has been widely used in my country for a long time, for example: transmission towers, wind power towers, solar thermal towers and other energy buildings, among which truss support structures with many advantages such as small footprint, high rigidity and high degree of assembly are used more frequently, but most of the truss support structures do not have earthquake-resistant devices. If they are installed in strong earthquake zones, when they are subjected to destructive lateral loads brought by the seismic shear waves of strong earthquakes, all loads will be concentrated in the support structure body. Therefore, the support structure body is very easy to be damaged in an earthquake, resulting in serious safety accidents.

Among them, the hinge support 5 can be installed on the main structure of the tower, one end of the first anti-bending beam 1 can be connected to the hinge support 5, and the other end can be connected to the connecting column 4. The first anti-bending beam 1 can rotate freely around the connection points between it and the hinge support 5 and the connecting column 4, respectively, but the present invention is not limited thereto. The tower energy dissipation support device described in this exemplary embodiment may not include the hinge support 5, that is, the first anti-bending beam 1 can be directly connected to the main structure of the tower, as long as the first anti-bending beam 1 can rotate freely around the connection point between it and the main structure of the tower.

[0056] In this embodiment, the first anti-bending beam 1 and the second anti-bending beam 2 can be a composite beam formed by splicing a number of rigid plates together. The materials of the first anti-bending beam 1 and the second anti-bending beam 2 should have sufficiently high bending resistance and be able to always remain rigid and not bend when subjected to seismic loads, so as to maintain the stability of the overall structure of the tower.

[0057] Further, the first anti-bending beam 1 may include a first connecting plate 12, a second connecting plate 13 and two first rigid plates 11, wherein the two first rigid plates 11 are arranged in parallel and side by side, the first connecting plate 12 extends from one end of the two first rigid plates 11 into between the two first rigid plates 11, and the first connecting plate 12 is arranged parallel to the first rigid plates 11, and the second connecting plate 13 extends from the other end of the two first rigid plates 11 into between the two first rigid plates 11, and the second connecting plate 13 is also arranged parallel to the first rigid plates 11, but the present invention is not limited to this. The number of first rigid plates 11 in the first anti-bending beam 1 may also be 1, 3 or more, and the number of connecting plates in the first anti-bending beam 1 may not be limited to the first connecting plate 12 and the second connecting plate 13, as long as the first rigid plate 11 and the connecting plates can be arranged in parallel and fixedly connected and combined together.

The two first rigid plates 11, the first connecting plate 12 and the second connecting plate 13 can also be fixedly connected by other means such as welding, riveting, etc., the first connecting plate 12 and the hinge support 5 can also be hinged by other means such as a pin, the ear plate 41 can also be installed on the upper end of the connecting column 4 by other connection methods such as one-piece molding and screw connection, the second connecting plate 13 and the ear plate 41 can also be hinged by other means such as a pin, and the second connecting plate 13 can also be directly hinged to the connecting column 4, as long as the second connecting plate 13 can rotate freely around the connecting column 4.

[0059] Furthermore, the two first rigid plates 11 can be channel steels respectively. When the two channel steels are arranged side by side and opposite to each other, their cross-sections can be roughly in the shape of an "I". In the groove of each channel steel, a number of stiffening ribs 111 are arranged side by side along the length direction of the channel steel. The stiffening ribs 111 can enhance the bending strength of the channel steel when bolt holes are opened on the plate surface of the channel steel, so that the channel steel can maintain rigidity and not bend after being subjected to the load imposed by an earthquake; in this embodiment, the number of stiffening ribs 111 on each channel steel is 4, but the present invention is not limited to this, and the number of stiffening ribs 111 can also be other positive integers other than 4; the structure of the two first rigid plates 11 is not limited to channel steels, and can also be other material structures that can meet the bending strength and rigidity requirements.

[0060] In this embodiment, one end of the energy-absorbing component 3 can be fixedly connected to the first anti-bending beam 1, and its connection point is located at the center of the first anti-bending beam 1, but the present invention is not limited to this.

[0062] Furthermore, the other end of the energy absorbing beam 31 is slidably connected to the limit plate 32, and a second type of hole 311 is opened at the connection between the energy absorbing beam 31 and the limit plate 32. A first type of hole 321 is opened on the limit plate 32 at a position corresponding to the first type of hole 321, which passes through the left and right sides of the limit plate 32. The first type of hole 321 is an oblong hole, and the second type of hole 311 is a circular hole. The limiting connector 33 can penetrate the first hole 321 and the second hole 311 at the same time to connect the energy absorbing beam 31 and the limiting plate 32 together. Under the action of external force, the energy absorbing beam 31 can drive the limiting connector 33 to slide in the first hole 321, thereby realizing relative sliding between the energy absorbing beam 31 and the limiting plate 32, and the sliding stroke is limited to the length range of the first hole 321, but the present invention is not limited to this. The first hole 321 on the limiting plate 32 can also be opened as a round hole, and the second hole 311 on the energy absorbing beam 31 can be opened as an oblong hole, or the first hole 321 and the second hole 311 can both be opened as oblong holes. In this way, after the energy absorbing beam 31 and the limiting plate 32 are connected by the limiting connector 33, relative sliding between the energy absorbing beam 31 and the limiting plate 32 can be realized, and the sliding stroke can also be limited to the length range of the oblong hole.

[0063] Furthermore, the number of the second-type holes 311 opened on the energy-absorbing beam 31 is 1, and the number of the first-type holes 321 opened on the limiting plate 32 and penetrating the left and right sides of the limiting plate 32 is also 1, but the present invention is not limited to this.

[0064] Furthermore, the limiting plate 32 has an arc-shaped structure, but the present invention is not limited thereto. The limiting plate 32 may also have a straight line, a rectangle or other shapes, as long as the lower end of the energy-absorbing beam 31 can be axially displaced in the first type of hole 321 on the limiting plate 32.

[0065] Furthermore, if Fig.10As shown, the energy absorbing beam 31 has a second hinged end 312 (also called a hinged support) for connection, which can be rotatably connected to one end of the arc-shaped plate 71 through bolts. The second hinged end 312 can be located at the body of the energy absorbing beam 31, which can be determined according to actual conditions. The second hinged end 312 is welded or integrated with the energy absorbing beam 31.

In addition, the connection method between the first end plate 22, the second end plate 23 and the two second rigid plates 21 may also be welding, riveting or other fasteners, not limited to bolt connection.

[0067] Furthermore, one end of the first end plate 22 is butt-jointed with the second end plate 23, and the other end is welded to the side wall of the connecting column 4; one end of the second end plate 23 is butt-jointed with the first end plate 22, and the other end is integrally formed with the limiting plate 32, but the present invention is not limited thereto, and the first end plate 22 may also be fixedly connected to the connecting column 4 by other connection methods such as bolt connection and integral forming, and the second end plate 23 may also be fixedly connected to the limiting plate 32 by other connection methods such as welding and bolt connection.

[0068] Further, the upper and lower ends of the connection between the first end plate 22 and the connecting column 4 are respectively installed with a sleeve type reinforcement ring 6, the sleeve type reinforcement ring 6 is sleeved on the outside of the connecting column 4, and the upper and lower end surfaces of the first end plate 22 are respectively abutted against the end surfaces of the sleeve type reinforcement ring 6 on the upper and lower sides thereof, and the installation of the sleeve type reinforcement ring 6 can strengthen the strength of the connection between the first end plate 22 and the connecting column 4, ensuring that the connection between the first end plate 22 and the connecting column 4 meets the strength requirements. Among them, the number of the sleeve type reinforcement rings 6 is 2, but the present invention is not limited thereto, and the number of the sleeve type reinforcement rings 6 can also be other positive integers except 2.

[0069] Furthermore, if Fig.11As shown, the second rigid plate 21 has a first hinge end 211 (also called a hinge support) for connection, which can be rotatably connected to the other end of the arc-shaped plate 71 by bolts. The first hinge end 211 is welded or integrally formed with the second rigid plate 21.

[0070] In this embodiment, if Fig. 9 As shown, the arc-shaped corner brace 7 may include an arc-shaped plate 71 and a buckling restraining component.

[0071] One end of the arc plate 71 is rotatably connected to the energy dissipation beam 31, and the other end is rotatably connected to the second anti-bending beam 2. For example, the other end of the arc angle brace 7 is hinged to the node plate (i.e., the second rigid plate 21). When the arc plate is subjected to stress, the buckling restraint assembly can restrain the out-of-plane deformation of the arc plate.

[0072] The buckling restraining assembly may include a first buckling restraining plate 72 and a second buckling restraining plate 73. The first and second buckling restraining plates are respectively located on both sides of the arc-shaped plate 71, and a space matching the thickness and deformation mode of the arc-shaped plate 71 is formed therebetween.

[0073] The arc-shaped angle brace also includes a fixing member capable of fixing the first and second flexure restraining plates.

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

[0075] Furthermore, the first and second buckling restraint plates are both arc-shaped plates, and the arc length sides of the two plates are provided with bolt holes distributed along the arc length and corresponding to each other.

[0076] Furthermore, the fixing member includes a plurality of bolts, the number of which is the same as the number of bolt holes on the buckling restraint plate and corresponds one to one.

[0077] Furthermore, a first bolt hole 711 and a second bolt hole 712 for connection may be opened at both ends of the arc-shaped plate 71 .

[0078] The energy dissipation process of the tower energy dissipation support device when subjected to earthquake load is described in detail below:

[0079] When the tower structure and the tower energy-absorbing support device are subjected to earthquake loads, the first rigid plate 11 can rotate around the hinge support 5 and the ear plate 41, and the energy-absorbing component 3 is simultaneously subjected to loads from the first anti-bending beam 1 and the second anti-bending beam 2 at the upper and lower ends. The energy-absorbing beam 31 first slides relative to the limit plate 32, that is, the lower end of the energy-absorbing beam 31 slides within the length of the oblong hole until the lower end of the energy-absorbing beam 31 slides to one end of the oblong hole. At this time, if the load continues to increase, the energy-absorbing beam 31 and the limit plate 32 will slide relative to each other. The relative sliding between the plates 32 cannot completely offset the load effect. Since the energy absorbing beam 31 is a deformable component, the energy absorbing beam 31 will be compressed by the support reaction force of the hinge support 5 and bend to further offset the load effect. During the entire loading process, the first anti-bending beam 1, the second anti-bending beam 2 and the connecting column 4 hardly bend and deform. The load on the entire tower structure can be basically offset by the relative sliding and bending in the energy absorbing component 3. Therefore, the original structure of the tower can remain stable in the earthquake load and be protected from damage. Since the buckling restraint component limits the deformation outside the plane of the arc angle support to the maximum extent, and at the same time restrains the deformation of the energy absorbing beam 31, the performance of the entire energy absorbing support device is greatly improved, and multi-stage energy consumption is achieved.

Fig.12 A schematic diagram of the structural deformation of the tower energy dissipation support device of exemplary embodiments 1 and 2 of the present invention when subjected to load is shown.

[0083] like Figure 8 and Fig.12 As shown in , the tower energy dissipation support device in this exemplary embodiment is arranged in the middle of the tower structure, and its overall structure is substantially the same as the structure of the tower energy dissipation support device arranged on the top of the tower structure in exemplary embodiment 1, wherein the first anti-bending beam 1 is arranged substantially parallel to the tower beam above it and the two can form a double-layer truss structure with upper and lower layers, one end of the first anti-bending beam 1 can be hinged to the hinge support 5 by bolts, and the other end can be connected to the ear plate 41 ( Figure 74. As shown in the figure, the first anti-bending beam 1 is hinged with bolts, but the present invention is not limited to this. One end of the first anti-bending beam 1 may also be hinged with the hinge support 5 by other connecting parts such as a pin, or the first anti-bending beam 1 may also be directly connected to the tower, as long as the first anti-bending beam 1 can rotate freely around the connection point with the tower; the other end of the first anti-bending beam 1 may also be hinged with the ear plate 41 by other connecting parts such as a pin, or the first anti-bending beam 1 may also be directly connected to the connecting column 4, as long as the first anti-bending beam 1 can rotate freely around the connection point with the connecting column 4; the ear plate 41 may also be installed on the outer wall of the connecting column 4 by one-piece molding, screw connection or other connection methods.

[0084] Furthermore, the upper and lower ends of the connection between the ear plate 41 and the connecting column 4 are respectively installed with a sleeve type reinforcement ring 6, the sleeve type reinforcement ring 6 is sleeved on the outside of the connecting column 4, and the upper and lower end surfaces of the ear plate 41 are respectively abutted against the end surfaces of the sleeve type reinforcement ring 6 on the upper and lower sides thereof, and the installation of the sleeve type reinforcement ring 6 can strengthen the strength of the connection between the ear plate 41 and the connecting column 4, ensuring that the connection between the ear plate 41 and the connecting column 4 meets the strength requirements. In this embodiment, the number of the sleeve type reinforcement rings 6 is 4, but the present invention is not limited thereto, and the number of the sleeve type reinforcement rings 6 can also be other positive integers other than 4.

[0085] In this exemplary embodiment, except for the above-mentioned structural features which are different from those in exemplary embodiment 1, the remaining structural features and the energy dissipation process when subjected to seismic loads are the same as those in exemplary embodiment 1. Therefore, in this exemplary embodiment, the structural features and energy dissipation processes that are the same as those in exemplary embodiment 1 will not be repeated.

[0086] Exemplary Embodiment 3

When the tower is subjected to the lateral load caused by the earthquake, the entire tower is deformed. The structural deformations at A and B are Fig.12 It can be seen that the energy-absorbing components in the tower energy-absorbing support device can bend and deform after being loaded, and at the same time, the lower end of the energy-absorbing beam can slide relative to the limit plate to jointly consume energy to offset the load. During the loading process, the first anti-bending beam, the second anti-bending beam and the connecting column hardly bend and deform, and the load on the entire tower structure can be basically offset by the relative sliding and bending in the energy-absorbing components. Therefore, the original structure of the tower can remain stable under seismic loads and be protected from damage.
