Description

Technical Field

[0001] The invention belongs to the technical field of building structure seismic reduction and isolation, and particularly relates to a conical self-correcting building seismic isolation rubber bearing. Background Art

[0002] Seismic isolation bearings refer to the supporting devices set up in the structure to meet the seismic isolation requirements. Seismic isolation bearings are to add a seismic isolation layer between the upper structure and the foundation. The main categories include seismic isolation rubber bearings, elastic sliding plate bearings, friction pendulum seismic isolation safety bearings, etc.

[0003] Traditional earthquake-resistant technology is to firmly connect the building's superstructure and foundation, that is, to build the house stronger, use thicker steel bars, and pour more concrete, but the earthquake-resistant effect is not ideal. The design of the seismic isolation bearing can effectively reduce the vibration and force of buildings or structures during earthquakes, thereby protecting the safety of their structures and internal facilities. This type of seismic isolation bearing is usually used in important buildings or structures, such as bridges, nuclear power plants, high-rise buildings, etc., to improve their seismic resistance and safety. If rubber seismic isolation bearings are installed to serve as a soft connection with the ground, this technology can offset about 80% of the energy of an earthquake.

[0004] However, the existing seismic isolation bearings still cannot solve the problem of correcting the deviation of the rubber bearings during construction. It is necessary to prepare the bearing fixing anchors in advance and make corrections and adjustments on site. This method requires additional clamps and cannot completely guarantee the deviation of the bearings.

[0005] Therefore, how to provide a conical self-correcting building seismic isolation rubber bearing is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0006] The main purpose of the present invention is to provide a conical self-correcting building seismic isolation rubber bearing to solve the above technical problems. The device is provided with a rubber column with a truncated cone structure. When the rubber column is deflected by an offset force, the truncated cone structure will enable the rubber column to quickly return to the state before the offset, eliminate the offset effect, and realize the automatic correction of the rubber column.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A conical self-correcting building seismic isolation rubber bearing comprises an upper flange, a rubber column and a lower flange. The upper flange is fixedly connected to one end of the rubber column, and the other end of the rubber column is fixedly connected to the lower flange. The rubber column is a truncated cone structure.

[0009] Furthermore, a plurality of reinforcing plates are arranged inside the rubber column.

[0010] Furthermore, the upper flange and the lower flange are both provided with connecting holes.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention is provided with a rubber column with a truncated cone structure. When the rubber column is deflected by a deflection force, the truncated cone structure enables the rubber column to quickly restore the state before the deflection, eliminates the deflection effect, and realizes automatic deviation correction of the rubber column.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 5 As shown, the present invention provides a conical self-correcting building seismic isolation rubber bearing, including an upper flange 1, a rubber column 2 and a lower flange 4, wherein the upper flange 1 is fixedly connected to one end of the rubber column 2, and the other end of the rubber column 2 is fixedly connected to the lower flange 4, and the rubber column 2 is a truncated cone structure. When the truncated cone structure of the rubber column 2 is subjected to an offset force, the truncated cone structure will deform, such as Figure 5The rubber column 2 shown is offset to one side. Due to the conical surface design of the truncated cone, the effect of the offset can be offset, the original offset of the seismic isolation rubber bearing is guaranteed, the safety of the building is ensured, and the offset effect of the rubber column 2 is improved.

[0022] In this embodiment, a plurality of reinforcing plates 3 are disposed inside the rubber column 2 , and the reinforcing plates 3 are used to increase the deflection force that the rubber column 2 itself can withstand, thereby increasing the strength of the rubber column 2 .

[0023] In this embodiment, the upper flange 1 and the lower flange 4 are both provided with connection holes, and the connection holes are used to connect the seismic isolation rubber bearing to the building.

[0024] Working principle: When in use, the seismic isolation rubber bearing is connected and fixed to the building through the connecting holes on the upper flange 1 and the lower flange 4. After fixation, when the building is subjected to the displacement force caused by earthquakes or typhoons, the rubber column 2 is deformed for buffering. At the same time, since the rubber column 2 is a truncated cone structure, one side of the rubber column 2 tilts and shifts to one side during deformation. Due to the conical surface design of the truncated cone, the influence of the displacement can be offset, thereby ensuring the original displacement of the seismic isolation rubber bearing, ensuring the safety of the building, and improving the displacement effect of the rubber column 2.

[0025] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
