[0026] In order to provide a further understanding of the purpose, structure, features and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0027] Please refer to Figure 1 , Figure 2 , Figure 3 ,and Figure 7 A horizontal limit system of a spring vibration isolation support according to an embodiment of the utility model includes an upper structure and a lower structure. The upper structure includes an upper structure column 61, an upper floor slab 71, and an upper structure beam 91; the lower structure includes a lower structure column 62, a lower floor slab 72, and a lower structure beam 92; the upper structure and the lower structure refer to conventional floors of a building connected to a vibration isolation layer.

[0028] It also includes a vibration isolation layer; when in use, a vibration isolation layer of about 1.5m is usually added between building floors to isolate the vibration of the lower structure from being transmitted to the upper structure.

[0029] The vibration isolation layer includes an upper pier 81, a lower pier 82, a spring vibration isolation support 1, a horizontal limit device 3 and a connecting piece; the spring vibration isolation support 1 connects the upper pier 81 and the lower pier 82, and the spring vibration isolation support 1 is a spring vibration isolator. The upper structure is fixed to the upper pier 81, and the lower structure is fixed to the lower pier 82; through the coordinated use of the horizontal limit device 3 and the spring vibration isolation support 1, the system has the effects of vertical vibration isolation and reliable transmission of earthquake action.

[0030] The connecting piece is a steel pipe, including an upper steel pipe 21 and a lower steel pipe 22; the upper part of the upper steel pipe 21 is inserted into the upper pier 81, the lower part of the upper steel pipe 21 is fixed with an upper connecting plate 41, the lower part of the lower steel pipe 22 is inserted into the lower pier 82, the upper part of the lower steel pipe 22 is fixed with a lower connecting plate 42, and the two ends of the horizontal limit device 3 are respectively connected to the upper connecting plate 41 and the lower connecting plate 42. The upper and lower connecting plates are connected by the horizontal limit device 3, and then connected to the upper and lower steel pipes, so as to ensure that the horizontal seismic action is transmitted from the lower structure and the horizontal limit device 3 to the upper structure. In addition, the horizontal limit device 3 will not affect the vibration isolation efficiency of the spring vibration isolation bearing, and the function is feasible and easy to construct.

[0031] The horizontal limit device 3 is a honeycomb beam, which is used as a component of the horizontal limit device. When a pipeline needs to be arranged between the upper and lower piers, the pipeline can pass through the holes of the honeycomb beam, and the height of the space occupied by the pipeline is reduced, further controlling the height of the vibration isolation layer, thereby bringing economic benefits. The horizontal limit device 3 includes two types, one is a through honeycomb beam, and the other is a non-through honeycomb beam. The two ends of the through honeycomb beam are respectively connected to the upper connecting plate 41 and the lower connecting plate 42. The horizontal limit device 3 can reliably transmit horizontal seismic effects. The non-through honeycomb beam includes a honeycomb beam section 31 and a node plate 13. The honeycomb beam section 31 is symmetrically connected and arranged on both sides of the node plate 13. The ends of the two honeycomb beam sections 31 away from the node plate 13 are respectively connected to the upper connecting plate 41 and the lower connecting plate 42. Through the slidable connection at the node plate 13, it is ensured that the non-through honeycomb beam can transmit the horizontal seismic effects in the corresponding direction, and does not interfere with the through honeycomb beam perpendicular to it to transmit the horizontal seismic effects in the vertical direction. By adopting two types of horizontal limit devices, it is convenient to use different types of horizontal limit devices according to specific design conditions, stress conditions and construction operation space. The two types of horizontal limit devices 3 can also be used in combination to ensure that the horizontal limit device 3 has a better application range.

[0032] The through honeycomb beam has a circular hole on the side connected to the upper connecting plate 41, and an oblong hole on the side connected to the lower connecting plate 42. The upper connecting plate 41 and the lower connecting plate 42 have circular holes at corresponding positions, and the through honeycomb beam is connected to the upper connecting plate and the lower connecting plate by high-strength bolts. When the through honeycomb beam is in use, the oblong hole can ensure that the through honeycomb beam contacts the lower connecting plate after a certain displacement along the oblong hole, ensuring the transmission of horizontal seismic action, and can cooperate with the vertical deformation of the spring vibration isolation support. At the same time, the oblong hole can enhance the flexibility of the structure, improve the adaptability to installation errors, and facilitate installation.

[0033] A circular hole is provided on one side of the honeycomb beam section 31 connected to the upper connecting plate 41 or the lower connecting plate 42, and an oblong hole is provided on one side of the honeycomb beam section 31 connected to the node plate 13, a universal bearing 14 is installed in the oblong hole, corresponding circular holes are provided on the upper connecting plate 41 and the lower connecting plate 42, and circular holes are provided on both sides of the node plate 13. The honeycomb beam section 31 is connected to the upper connecting plate 41 or the lower connecting plate 42 by high-strength bolts, and a pin 5' is used to connect the honeycomb beam section 31 and the node plate 13. The universal bearing 14 is a fisheye bearing, which ensures that the pin can rotate arbitrarily in the universal bearing 14 to prevent it from getting stuck. The universal bearing 14 ensures that the honeycomb beam section 31 can rotate freely at the node plate 13 and is not stuck at the node. The structure of the non-through honeycomb beam has a certain deformation capacity, which reduces the bending moment and shear force at the node.

[0034] Bolts 11 are arranged around the parts of the upper steel pipe 21 and the lower steel pipe 22 inserted into the upper and lower piers. The bolts 11 strengthen the anchoring effect between the steel pipe and the pier concrete, and can transmit vertical shear force. The connection strength between the steel pipe and the pier is ensured, which is conducive to the transmission of force. The ends of the upper steel pipe 21 and the lower steel pipe 22 are respectively provided with sealing plates 10. By designing the sealing plates 10, the steel pipe is sealed, air is isolated from entering the steel pipe, and the steel pipe is prevented from rusting. It is ensured to have a long service life.

[0035] like Figure 1 and Figure 2Two spring vibration isolation supports 1 are arranged between the upper pier 81 and the lower pier 82, and four groups of horizontal limit devices 3 are installed between the upper pier and the lower pier. The four groups of horizontal limit devices 3 include two groups of transversely arranged through honeycomb beams and two groups of longitudinally arranged through honeycomb beams. Furthermore, the two groups of transversely arranged through honeycomb beams are arranged between the two spring vibration isolation supports 1, and the two groups of longitudinally arranged through honeycomb beams are symmetrically arranged on both sides of the spring vibration isolation supports 1. The spring vibration isolator 1 and the horizontal limit device are compactly arranged so that the system has the effects of vertical vibration isolation and reliable transmission of horizontal seismic effects at the same time, thereby achieving the comprehensive effect of "dual control of vibration and shock". By setting four groups of horizontal limit devices, it is ensured that the system has higher safety redundancy under the action of earthquakes.

[0036] like Figure 4 Four spring vibration isolation supports 1 are installed at the four corners of the upper pier 81 and the lower pier 82, and two sets of horizontal limit devices 3 are installed in the middle between the upper pier and the lower pier. The upper and lower steel pipes 21 and 22 are respectively inserted into the upper and lower piers, and two horizontal limit devices 3 are set in the transverse and longitudinal directions. Among them, one direction is a through honeycomb beam, and the other direction is a non-through honeycomb beam. The through honeycomb beam is fixed with a node plate 13 at the part perpendicularly intersecting with the non-through honeycomb beam. The two sides of the node plate 13 are connected to the honeycomb beam section 31 through a pin 5'. By setting spring vibration isolation supports 1 at the four corners, the vertical force of the system is ensured to be evenly distributed. Through the horizontal limit devices 3 in two directions connected vertically, the spring vibration isolator 1 and the horizontal limit device 3 are compactly arranged, so that the system has the effects of vertical vibration isolation and reliable transmission of horizontal earthquake action, and the comprehensive effect of "dual control of vibration and vibration" can be achieved. At the same time, the size of the column pier can be reduced and the utilization rate of the building space can be improved. The combined use of the through honeycomb beam and the non-through honeycomb beam ensures that the deformations in the horizontal and vertical directions of the vibration dual-control system do not affect each other. Example 1

[0037] like Figure 1 , Figure 2 and Figure 3 Two spring isolators 1 are arranged between the upper and lower piers, and two groups of horizontal limit devices 3 are arranged in the horizontal and vertical directions, which are of the same type and are through honeycomb beams. The connecting parts are steel pipes, and the upper and lower steel pipes are inserted into the upper and lower piers. The upper and lower connecting plates 41 and 42 are welded and connected with the upper and lower steel pipes. Bolts 11 are arranged around the part of the steel pipe inserted into the pier. The function of the bolts 11 is to strengthen the anchoring effect between the steel pipe and the pier concrete, and can transmit vertical shear force. The function of the sealing plate 10 at the end of the steel pipe is to isolate air from entering the interior of the steel pipe to prevent the steel pipe from rusting.

[0038] The through honeycomb beam has a circular hole on the side connected to the upper connecting plate 41, and an oblong hole on the side connected to the lower connecting plate 42. The size parameters of the oblong hole are determined according to the simulation results of the vertical vibration of the engineering structure. The upper and lower connecting plates have circular holes at corresponding positions, and the through honeycomb beam and the upper and lower connecting plates are connected with high-strength bolts. The upper and lower connecting plates are welded to the upper and lower steel pipes.

[0039] When the building is in normal use, the spring isolator vibrates vertically, which plays the role of transmitting vertical loads and isolating vibrations. At the same time, the upper steel pipe together with the upper connecting plate moves with the upper structure, driving the through honeycomb beam to produce vertical displacement and rotation, and the horizontal limit device does not affect the vibration isolation efficiency. When the building is subjected to horizontal earthquakes, the upper and lower structures undergo interlayer deformation, and the through honeycomb beam contacts the lower connecting plate after a certain displacement along the oblong hole, so that the horizontal earthquake can be transmitted from the lower structure and the horizontal limit device to the upper structure. When the building is subjected to vibration and earthquake at the same time, the spring isolator plays the role of transmitting vertical loads and isolating vibrations, and the upper and lower steel pipes and the horizontal limit device play the role of transmitting horizontal loads, and the two do not interfere with each other. Example 2

[0040] like Figure 3 , Figure 4 , Figure 5 and Figure 6 Four spring isolators 1 are arranged at the four corners of the upper and lower piers, and two groups of horizontal limit devices 3 are arranged in the transverse and longitudinal directions. One direction is a through honeycomb beam, and the perpendicular direction is a non-through honeycomb beam.

[0041] The connecting piece is a steel pipe, and the upper and lower steel pipes are inserted into the upper and lower piers. Studs 11 are arranged around the part inserted into the pier. The function of the studs 11 is to strengthen the anchoring effect between the steel pipe and the pier concrete, and to transmit vertical shear force. The function of the sealing plate 10 at the end of the steel pipe is to isolate air from entering the steel pipe and prevent the steel pipe from rusting.

[0042] The through honeycomb beam has a circular hole on the side connected to the upper connecting plate 41, and an oblong hole on the side connected to the lower connecting plate 42. The size parameters of the oblong hole are determined according to the simulation results of the vertical vibration of the engineering structure. The upper and lower connecting plates have circular holes at corresponding positions, and the through honeycomb beam is connected to the upper and lower connecting plates 41 and 42 using high-strength bolts. The non-through honeycomb beam has a circular hole on the side connected to the upper and lower connecting plates 41 and 42, and an oblong hole on the side connected to the node plate 13. A universal bearing 14 is installed in the oblong hole, and the size parameters of the oblong hole are determined according to the simulation results of the vertical vibration of the engineering structure. The upper and lower connecting plates have circular holes at corresponding positions, and the through honeycomb beam is provided with a node plate 13 at the position perpendicularly intersecting the non-through honeycomb beam. The node plate 13 has a circular hole at the corresponding position, and the non-through honeycomb beam is connected to the upper and lower connecting plates using high-strength bolts 5, and the non-through honeycomb beam is connected to the node plate 13 on the through honeycomb beam using a pin 5'.

[0043] When the building is in normal use, the spring isolator vibrates vertically, which plays the role of transmitting vertical load and vibration isolation. At the same time, the upper steel pipe and the upper connecting plate move with the upper structure, driving the through / non-through honeycomb beams to produce vertical displacement and rotation, and the horizontal limit device does not affect the vibration isolation efficiency. When the building is subjected to horizontal earthquake, the upper and lower structures produce interlayer deformation, the through honeycomb beam produces a certain displacement along the oblong hole and then contacts the lower connecting plate, the two sections of non-through honeycomb beams produce a certain displacement along the oblong hole, and the non-through honeycomb beams on both sides contact the through honeycomb beams to achieve force transmission, so the horizontal earthquake can be transmitted from the lower structure and the horizontal limit device to the upper structure. And the degrees of freedom of the nodes connecting the non-through honeycomb beams on both sides and the through honeycomb beams are not constrained, so the horizontal and vertical deformations of the horizontal limit system do not interfere with each other. When the building is subjected to vertical vibration and earthquake at the same time, the spring isolator plays the role of transmitting vertical load and vibration isolation, and the upper and lower steel pipes and the horizontal limit device play the role of transmitting horizontal loads. The two do not interfere with each other, and the principle is the same as above.

[0044] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any changes and modifications made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
