The structure is allowed to enter the plastic deformation stage under seismic action to protect the overall structure from collapse. The core idea of this method is to utilize the plastic properties of structural members to absorb and dissipate seismic energy, thereby ensuring the overall stability of the building.

[0004] However, this traditional seismic design method makes plastic damage concentrated on the main structural members of the building. The main load-bearing members of the building structure will suffer serious plastic damage, and it is difficult to repair after the earthquake. It often needs to be demolished and rebuilt.

[0039] Embodiment 1

[0040] As Figure 1 As shown in the figure, this embodiment discloses an integral rocking energy-dissipating prefabricated structure, which includes a plurality of floor components 100, connecting columns 200, and energy-dissipating components 260. The connecting columns 200 are fixed on the floor components 100 and are perpendicular to the floor components 100. The plurality of floor components 100 are all arranged along the horizontal direction. A hemispherical protruding portion 240 is provided at the first end of the connecting column 200, and a hemispherical groove portion 250 is provided at the second end. Two adjacent floor components 100 are connected to each other through the cooperation of the protruding portion 240 and the groove portion 250 of the connecting column 200. The energy-dissipating component 260 includes a circular ring 261 and connecting rods 263. The circular rings 261 are respectively arranged on the outer surfaces of the first end and the second end of the connecting column 200, and a plurality of vertical mounting holes 262 are provided on the circular rings 261. When two adjacent floor components 100 are connected by the connecting column 200, the plurality of connecting rods 263 are respectively inserted into the corresponding mounting holes 262 of the adjacent circular rings 261 on the two connecting columns 200 along the vertical direction, and both ends of the connecting rods 263 are respectively fixed on the circular rings 261 on the two connecting columns 200.

[0041] As Figure 1As shown in the figure, in this embodiment, the overall sway energy dissipation prefabricated structure is provided with a total of five floor components 100. Among them, a hemispherical convex portion 240 is provided at the bottom of the connecting column 200 on the top floor component 100. The top end of the connecting column 200 on the four lower floor components 100 extends upward and the bottom end extends downward, and a hemispherical groove portion 250 is provided at the top end of the connecting column 200 on the four lower floor components 100, and a hemispherical convex portion 240 is provided at the bottom end. The upper floor component 100 is connected to the adjacent lower floor component 100 through the connecting column 200. The specific connection method is to install the convex portion 240 at the bottom end of the connecting column 200 of the upper floor component 100 into the groove portion 250 at the top end of the connecting column 200 of the lower floor component 100. The circular ring 261 on the outer surface of the connecting column 200 of the upper floor component 100 is close to the circular ring 261 on the outer surface of the connecting column 200 of the lower floor component 100, and the mounting holes 262 on both of them correspond one by one. The number of connecting rods 263 is the same as the number of mounting holes 262 on the circular ring 261. The connecting rods 263 are inserted into the corresponding mounting holes 262 of the two circular rings 261 along the vertical direction and are fixedly connected to the two circular rings 261.

[0042] Specifically, threaded portions are provided at both the top and bottom of the connecting rod 263. The threaded portion at the top of the connecting rod 263 is fixed to the upper part of the circular ring 261 on the outer surface of the connecting column 200 of the upper floor component 100 through a nut, and the threaded portion at the bottom of the connecting rod 263 is fixed to the bottom of the circular ring 261 on the outer surface of the connecting column 200 of the lower floor component 100 through a nut.

[0043] During an earthquake, since the floors are not rigidly connected, the convex portion 240 at the bottom of the connecting column 200 of the upper floor component 100 can slide in the groove portion 250 at the top of the connecting column 200 of the lower floor component 100, so that the floor components 100 can swing relative to each other to dissipate the energy input by the earthquake. And because the convex portion 240 at the bottom of the connecting column 200 of the upper floor component 100 meshes with the groove portion 250 at the top of the connecting column 200 of the lower floor component 100, and due to the constraints between the circular ring 261 and the connecting rod 263, relative sliding does not occur.

[0044] In addition, when the floor components 100 can swing relative to each other, the energy dissipation components 260 (connecting rods 263, circular rings 261) will be deformed and damaged to further absorb the energy generated by the earthquake.

[0045] Therefore, the above structural design can effectively protect the main structure from being damaged or undergoing plastic deformation during an earthquake. The energy generated by the earthquake is dissipated through the swaying between the floor components 100 and the deformation of the energy dissipation components 260. After the earthquake, only the energy dissipation elements need to be repaired and replaced, without the need to demolish and reconstruct the entire structure, greatly reducing the post-earthquake reconstruction workload.

[0046] As Figure 2 shown, the energy dissipation component 260 further includes reinforcing ribs 264. A circle of reinforcing ribs 264 is provided at the bottom of each ring 261. The reinforcing ribs 264 are arranged at intervals along the circumferential direction of the outer surface of the connecting column 200, and the reinforcing ribs 264 are perpendicular to the outer surface of the connecting column 200. The reinforcing ribs 264 are trapezoidal in shape. The reinforcing ribs 264 are connected to the bottom of the ring 261, and the reinforcing ribs 264 are used to increase the strength of the ring 261.

[0047] As Figure 2 shown, the position with the minimum diameter of the connecting rod 263 is located at the midpoint of the connecting rod 263. Specifically, the diameters at both ends of the connecting rod 263 are the same, and the diameter of the connecting rod 263 gradually decreases from both ends towards its midpoint. Such a structural design is to set the center of the connecting rod 263 as a weak point. When an earthquake occurs, the center of the connecting rod 263 is prone to deformation and damage, thereby absorbing the energy generated by the earthquake. Optionally, the material of the connecting rod 263 is steel.

[0048] As Figures 3 - 13 shown, multiple parallel connecting columns 200 are provided on the same floor component 100, including connecting middle columns 210, connecting side columns 220, and connecting corner columns 230. The connecting middle column 210 is located at the middle position of the floor component 100, and a horizontal outer strengthening ring 265 is provided on its outer surface. The outer strengthening ring 265 is provided with cantilever beams 266 extending in four directions, and the central angle between two adjacent cantilever beams 266 is 90°. The four cantilever beams 266 form a cross shape. The connecting side column 220 is located at the side position of the floor component 100, and a horizontal outer strengthening ring 265 is provided on its outer surface. The outer strengthening ring 265 is provided with cantilever beams 266 extending in three directions, and the central angle between two adjacent cantilever beams 266 is 90°. The three cantilever beams 266 form a T shape. The connecting corner column 230 is located at the corner position of the floor component 100, and a horizontal outer strengthening ring 265 is provided on its outer surface. The outer strengthening ring 265 is provided with cantilever beams 266 extending in two directions, and the central angle between two adjacent cantilever beams 266 is 90°. The two cantilever beams 266 form an L shape. The floor component 100 includes a plurality of I-beams 110, and the I-beams 110 are used to connect the connecting middle columns 210, connecting side columns 220, and connecting corner columns 230, thereby forming the overall framework of the floor component 100.

[0049] AsFigure 3 , 7 As shown, in this embodiment, there are 9 connecting columns 200 provided on each floor component 100, which can be classified into: connecting middle columns 210, connecting side columns 220, and connecting corner columns 230 according to types. Among them, there is 1 connecting middle column 210, which is arranged at the exact center of the floor component 100. There are 4 connecting side columns 220, which are respectively located in the front, rear, left, and right directions of the connecting middle column 210, and the cantilever beam 266 of the connecting middle column 210 and the cantilever beam 266 of the connecting side column 220 are fixedly connected through an I-shaped steel beam 110. The 9 connecting columns 200 form a structure in the shape of a Chinese character 'tian' (field). Among them, there are 4 connecting corner columns 230, and the 4 connecting corner columns 230 are respectively located at the four corners of the structure in the shape of a Chinese character 'tian' (field), and the cantilever beam 266 of the connecting corner column 230 and the cantilever beam 266 of the connecting side column 220 are fixedly connected through an I-shaped steel beam 110.

[0050] In this embodiment, each connecting column 200 is a prefabricated component. After being produced in the factory, it is transported to the site for assembly.

[0051] Optionally, the cantilever beam 266 is of an I-shaped structure, and its cross-sectional shape is exactly the same as that of the I-shaped steel beam 110, so as to facilitate the connection between the cantilever beam 266 and the I-shaped steel beam 110. Among them, the cantilever beam 266 and the working steel beam are connected by high-strength bolts.

[0052] As Figure 5 shown, further, the floor component 100 further includes a concrete slab 120, and the concrete slab 120 is fixed on the frame formed by the connecting columns 200 and the I-shaped steel beam 110. In this embodiment, there are 4 concrete slabs 120, and the 4 concrete slabs 120 are respectively fixedly installed in each small square of the frame structure in the shape of a Chinese character 'tian' (field).

[0053] As Figure 4 , 5 shown, in this embodiment, the structure of the connecting columns 200 of the floor component 100 at the top layer is different from that of the connecting columns 200 of the floor components 100 at other layers. Since the connecting columns 200 of the floor component 100 at the top layer do not need to be connected to other components, a hemispherical groove portion 250 is not provided at the top of the connecting columns 200 of the floor component 100 at the top layer. The other structures of the connecting columns 200 of the floor component 100 at the top layer are the same as those of the connecting columns 200 of the floor components 100 at the four lower layers.

[0054] As Figure 1 , 13As shown, preferably, the overall rocking energy-dissipating prefabricated structure further includes bottom columns. There are 9 bottom columns, and the 9 identical bottom columns respectively correspond to the respective connecting columns 200 in the floor assembly 100 in terms of position. The bottom of the bottom columns is fixedly installed on the foundation 400, and the top is provided with a hemispherical groove portion 250. The outer surface of the top of the bottom columns is provided with a ring 261, and a plurality of mounting holes 262 are provided on the ring 261. The groove portion 250 at the top of the bottom columns is connected to the protruding portion 240 at the bottom end of the connecting column 200 of the lowermost floor assembly 100.

[0055] As Figure 6 , 15 shown, the overall rocking energy-dissipating prefabricated structure further includes a self-centering assembly. The self-centering assembly includes prestressed steel strands 300, a first anchor 310, and a second anchor 320. The first anchor 310 is fixed inside the foundation 400, the second anchor 320 is fixed at the top of the connecting column 200 of the topmost floor assembly 100, and the prestressed steel strands 300 pass through the inside of the connecting columns 200 of each floor assembly 100, and both ends thereof are respectively connected to the first anchor 310 and the second anchor 320. Correspondingly, there are 9 groups of self-centering assemblies, and the 9 groups of self-centering assemblies are respectively installed corresponding to the 9 connecting columns 200.

[0056] In this embodiment, during the installation process, a preset tension (i.e., pre-tension) is applied to the prestressed steel strands 300 through a tensioning device, and then fixed at both ends of the structure with anchors. This pre-tension will generate compressive stress inside the structure. When the structure is subjected to external loads (such as seismic forces), these compressive stresses can offset part of the tensile stress, thereby improving the bearing capacity and stiffness of the structure. And the prestressed steel strands 300 have extremely high strength. The prestressed steel strands 300 penetrate the entire building structure and are fixed at the foundation 400 and the top with the first anchor 310 and the second anchor 320. When an earthquake occurs, the building structure can undergo inter-story rocking, and due to the high elasticity and pre-tension of the prestressed steel strands 300, it can help the building automatically return to its original position after rocking, reducing permanent deformation, and thus having the "self-centering" function.

[0057] The floor components 100 of the overall rocking energy-dissipating prefabricated structure in this embodiment are not rigidly connected. Through the cooperation of the hemispherical groove portion 250 and the hemispherical protrusion portion 240 (vertical embedded connection), the floor components 100 can rock during an earthquake (relative movement occurs between the connected connecting columns 200). Moreover, through the rocking between floors and the deformation of the energy-dissipating component 260, the energy input by the earthquake can be dissipated, protecting the main structure from earthquake damage. After the earthquake, only the damaged energy-dissipating components 260 such as the connecting rod 263 and the ring 261 need to be repaired and replaced, greatly reducing the post-earthquake reconstruction workload. In addition, the connecting columns 200 are connected through the hemispherical groove portion 250 and the hemispherical protrusion portion 240, which is suitable for the rocking movement trend between floors and can resist the shear force generated during the rocking process. And the prestressed steel strand 300 runs through the entire building structure, enabling the overall building structure to have a self-resetting function, and reducing the deformation of the structure relying on its own self-resetting function after a strong earthquake. Compared with other steel structure systems, the overall rocking energy-dissipating prefabricated structure in this embodiment adopts the concept of prefabricated buildings, with a fast construction speed, and can effectively ensure the post-earthquake function of the entire building structure, and has important practical significance for the post-earthquake recovery of the entire city.

[0058] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention. However, the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
