Description

Technical Field

[0001] The utility model relates to an adaptive horizontal energy-dissipating combined support. Background Art

[0002] Horizontal rubber isolation bearings are a simple and effective isolation technology and have been widely used in various low-rise and medium-rise buildings.

[0003] At present, a Chinese patent with authorization announcement number CN209602947U discloses a seismic isolation rubber bearing, which includes an upper bearing plate, a lower bearing plate, a rubber body and a limit assembly; the rubber body is fixedly arranged between the upper bearing plate and the lower bearing plate, the top surface of the rubber body is fixedly connected to the bottom surface of the upper bearing plate, and the bottom surface is fixedly connected to the top surface of the lower bearing plate; the limit assembly includes a retaining wall and a middle seat plate; the retaining wall is arranged on the bottom surface of the upper bearing plate; the middle seat plate is arranged around the rubber body, and includes a vertical part and a horizontal part, the top end of the vertical part is located between the retaining wall and the rubber body, and the horizontal part is fixedly connected to the lower bearing plate.

[0004] When the horizontal displacement of the rubber body is large, the vertical part in the limiting assembly blocks the rubber body, and the retaining wall blocks the vertical part.

[0005] This type of seismic isolation rubber bearing has excessive damping under small earthquakes, and there is initial aerodynamic force, resulting in poor seismic isolation effect; under large earthquakes, the damping force is insufficient and cannot effectively suppress horizontal displacement. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide an adaptive horizontal energy dissipation combined support to achieve the effect of adaptive horizontal energy dissipation.

[0007] In order to solve the above technical problems, the technical solution of the utility model is: an adaptive horizontal energy-absorbing combined support, comprising a base plate and a rubber seismic isolation support fixed on the base plate, the rubber seismic isolation support is fixedly connected to an end plate on the side facing away from the base plate, a plurality of seat bodies are fixedly connected to the base plate, the plurality of seat bodies are arranged around the rubber seismic isolation support, the seat body is slidably connected to a guide pressure plate along its own height direction, the end plate moves horizontally and causes the guide pressure plate to move along its own height direction through a conduction component.

[0008] To implement the above technical solution, the concrete is located above the end plate, and the end plate on the rubber seismic isolation bearing moves horizontally in any direction under an earthquake. The guide pressure plate is moved along its own height direction through the conduction component, so that the friction between the guide pressure plate and the concrete is increased, thereby suppressing the horizontal movement of the concrete relative to it to consume energy; when the end plate on the rubber seismic isolation bearing has a large displacement, the energy consumption is large; when the end plate on the rubber seismic isolation bearing has a small displacement, the energy consumption is small, thereby realizing adaptive horizontal energy consumption.

[0009] As a preferred solution of the utility model, the conduction component includes a sliding hole, a conduction groove, a lifting rod, a lifting block, a wedge surface, and a conduction surface. The conduction groove is opened on the side wall of the end plate, one end of the lifting rod is slidably connected to the conduction groove, and the other end of the lifting rod is slidably connected to the sliding hole. The sliding hole is opened on the seat body, the wedge surface is opened on the lifting rod and is located in the sliding hole, the conduction surface is opened on the lifting block and conflicts with the wedge surface, and the guide pressure plate is connected to the lifting block through a guide column.

[0010] To implement the above technical solution, when the end plate of the rubber seismic isolation bearing moves horizontally in any direction under an earthquake, the inner wall of the conduction groove contacts the jacking rod, causing the jacking rod to move along the length direction of the sliding hole, and the conduction surface to move along the wedge surface, thereby causing the jacking block to move along its own height direction. Moreover, the greater the displacement of the jacking rod, the greater the displacement of the jacking block, thereby increasing the displacement of the guide pressure plate, thereby suppressing the horizontal movement of the concrete and performing adaptive energy consumption.

[0011] As a preferred solution of the utility model, the jacking block is provided with a threaded section, the threaded section is threadedly connected with an adjusting nut, and the adjusting nut is in contact with the lower surface of the guide pressure plate through a guide assembly.

[0012] To implement the above technical solution, the adjusting nut is rotated, and the height position of the guide pressure plate is adjusted through the guide assembly, so that the preload force under static conditions can be adjusted by lifting and lowering, and the guide pressure plate can be easily replaced.

[0013] As a preferred solution of the utility model, the guide assembly includes a limit washer and a disc spring. The limit washer is sleeved on the outside of the guide column and placed on the adjusting nut. The disc spring is sleeved on the guide column and one end of the disc spring is in contact with the guide pressure plate, and the other end of the disc spring is in contact with the limit washer.

[0014] To implement the above technical solution, the adjusting nut is rotated, and the limit gasket is moved synchronously with the adjusting nut through the conduction effect of the threaded section to adjust the height position of the guide pressure plate. Due to the use of disc springs, the jacking deformation is converted into positive pressure, and the jacking deformation is released to avoid structural jamming or damage.

[0015] As a preferred solution of the utility model, the disc springs are provided in plurality and are stacked.

[0016] Implement the above technical solution to improve structural strength.

[0017] As a preferred solution of the utility model, a high-hardness wear-resistant rubber is fixedly connected to the side of the guide pressure plate facing away from the seat body.

[0018] To implement the above technical solution, the provision of high-hardness wear-resistant rubber improves the protection of the guide pressure plate, and only the high-hardness wear-resistant rubber needs to be replaced, thereby reducing the subsequent maintenance costs.

[0019] As a preferred solution of the utility model, four of the seat bodies are provided, the cross section of the end plate is square, and one of the seat bodies is provided on each side of the end plate.

[0020] The implementation of the above technical solution reduces the production cost and ensures that all the lifting rods move synchronously when the end plate moves in any horizontal direction. BRIEF DESCRIPTION OF THE DRAWINGS
