TECHNICAL FIELD
[0001] The utility model relates to a rocking isolation bearing device. BACKGROUND
[0002] In recent years, earthquakes occur frequently in China, and the houses in rural areas are seriously damaged in the earthquakes, which brings serious disaster to the local rural areas. Since the economy is underdeveloped and the awareness of earthquake prevention and disaster reduction is weak, one of the reasons for the serious earthquake disaster is that there are many defects in the design, materials and construction of rural buildings. Therefore, it is necessary to design a low-cost isolation bearing that can reduce horizontal and vertical earthquakes in function. SUMMARY
[0003] In view of the above technical problems, the utility model provides a rocking isolation bearing device.

[0005] A rocking isolation bearing device comprises:
[0006] a bearing;
[0007] a steering ball base arranged on the upper part of the bearing;
[0008] a steering ball installed on the steering ball base;
[0009] two internal high compression springs arranged on the steering ball base and located on both sides of the steering ball, and the top parts of the two internal high compression springs are fixedly connected with the top plate on the upper part of the steering ball respectively;
[0010] a disc spring arranged on the top plate;
[0011] a limiting assembly arranged on the disc spring;
[0012] four U-shaped steels arranged on the bearing and annularly distributed outside the steering ball base, and the top parts of the four U-shaped steels are connected with each other.
[0013] The limiting assembly comprises a horizontal plate and a cylinder arranged at the bottom of the horizontal plate, and the disc spring is arranged in the cylinder.
[0014] The external high compression spring is vertically arranged in the U-shaped steel.
[0015] The bearing is composed of a plurality of horizontal steel plates arranged from top to bottom, and rubber plates are arranged between adjacent horizontal steel plates.
[0016] A plurality of balls are arranged between the steering ball and the steering ball base.
[0017] The utility model has the advantages of:
[0018] 1. The utility model solves the technical of traditional rural building not resisting earthquake, the utility model cost is low, can give attention to building left and right shock absorption, upper and lower vibration isolation technology simultaneously, and has the self-resetting function.
[0019] 2. The utility model is used for rural building foundation and upper structure connecting position, has the effect of vertical vibration isolation, horizontal two direction shock absorption. When the earthquake, longitudinal wave arrives first and produces vertical earthquake force, at this moment, the rubber vibration isolation support isolates the earthquake, when the transverse wave arrives, because the transverse wave has big destructive power to the building, produces horizontal force, by U-shaped steel and high compression spring left and right swing deformation energy dissipation, simultaneously, the disc spring swings forward and backward with the ball and compresses to produce tiny deformation energy dissipation. U-shaped steel is yielded and dissipated energy by vertical force and horizontal force, simultaneously, the compression spring provides restoring force, the ball in the lower part of disc spring is not stressed but provides the disc spring with the direction of sliding to all around.
[0020] 3. The utility model gives attention to the double effect of shock absorption and vibration isolation, and has the swing self-resetting function. Can be installed between rural self-built house upper structure and foundation, when the earthquake, the shock absorption and vibration isolation combination can effectively reduce the energy of seismic wave, thereby reducing the danger of structure collapse.

[0025] In order to make the purpose, technical scheme and advantage of the utility model more clear and explicit, the utility model is further explained in detail below in connection with specific embodiments and referring to the drawings. It should be understood that these descriptions are only exemplary, and are not to limit the scope of the utility model. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0026] As Figs. 1 to 3As shown, a swing reduction isolation bearing device, comprising: a bearing 1; a steering ball base 9 arranged on the upper part of the bearing 1; a steering ball 8 mounted on the steering ball base 9; two internal high compression springs 4 arranged on the steering ball base 9 and located on both sides of the steering ball 8, and the top parts thereof are fixedly connected with the top plate 7 on the upper part of the steering ball 8 respectively; a disc spring 5 arranged on the top plate 7; a limiting assembly 6 arranged on the disc spring 5; four U-shaped steels 3 arranged on the bearing 1 and annularly distributed on the outer side of the steering ball base 9, and the top parts thereof are connected with each other. The limiting assembly 6 comprises a horizontal plate and a cylinder arranged on the bottom of the horizontal plate, and the disc spring 5 is arranged in the cylinder. The external high compression spring 10 is vertically arranged in the U-shaped steel 3. The bearing 1 is composed of a plurality of horizontal steel plates arranged from top to bottom, and rubber plates are arranged between adjacent horizontal steel plates. The steering ball 8 and the steering ball base 9 are provided with a plurality of balls 2.
[0027] In use, the utility model is installed between the upper structure and the foundation, the small earthquake vertical seismic force is borne by the bearing 1 first, the medium and large earthquakes are borne by the disc spring 5 and the U-shaped steel 3 on both sides, the horizontal earthquake is sheared and hysteresis deformed by the U-shaped steel 3 left and right, and the external high compression spring 10 can provide self-resetting function, the steering ball 8 rotates horizontally in the steering ball base 9 along the direction of the earthquake by the ball 2, and the internal high compression spring 4 can provide self-resetting function. Since the self-weight of the upper structure of rural building is lighter, the disc spring 5, the U-shaped steel 3, the external high compression spring 10 and the internal high compression spring 4 can provide vertical supporting force while having toughness and ductility. The disc spring 5 is in a compressed state, the top plate 7 rotates with the steering ball 8, and the disc spring 5 also rotates and extrudes under the structure self-weight pressure, the U-shaped steel 3 should have a lower yield point in the design, so that the toughness and ductility are higher, the rigidity is smaller than that of the external high compression spring 10 and the internal high compression spring 4, and the self-recovery state can be achieved, and the yield rigidity of the disc spring 5 is much larger than that of the external high compression spring 10, the internal high compression spring 4 and the U-shaped steel 3.
