Embodiment 1

[0013] Embodiment one: see figure 1 and figure 2 , the three-dimensional energy-dissipating shock-absorbing device includes a base plate 1, a top plate 11, and a horizontal interlayer steel plate rubber pad 2. The lower part of the horizontal interlayer steel plate rubber pad 2 is connected to the bottom plate 1, and the upper part is connected to the lower connecting plate 3 to form a horizontal shock absorber. It includes a core column 6, a vertical shock absorbing support system and a guide force transmission sleeve 10, the horizontal shock absorber and an upper connecting plate 4 are consolidated by bolts, and a core column 6 is fixed on the upper connection In the middle of the plate 4, a vertical main shock absorber is arranged on the upper part of the core column 6. The vertical main shock absorber is formed by vertically overlapping and vulcanizing the polymer material 9 and the interlayer steel plate 7. The vertical main shock absorber A damping rod 8 is arranged in...

Embodiment 2

[0014] Embodiment 2: This embodiment is basically the same as Embodiment 1, and the special feature is that the polymer material 9 is a high damping polymer elastic material. Spring 5 is a combined disk spring. The damping rods 8 are lead damping rods, and two to four damping rods 8 are evenly arranged along the circumferential direction inside the vertical main shock absorber.

Embodiment 3

[0015] Embodiment 3: This three-dimensional energy-dissipating shock absorber is divided into two main parts, wherein the lower part is the horizontal shock absorber of the device, which adopts the commonly used sandwich steel plate rubber pad 2 at present, and its diameter, height and the setting of lead-free core in the middle are set according to The overall needs and the load carried by the upper part are selected. The sandwich steel plate rubber pad 2 is consolidated with the foundation (lower structure) through the bottom plate 1 of the lower part, and the upper part and the lower connecting plate 3 are vulcanized and fixed. The upper part of the lower connecting plate 3 is a vertical damping system. First, the core column 6 is welded to the center of the upper connecting plate 4, and then the disc spring 5 is inserted. The specification and quantity of the disc spring 5 can be adjusted according to the bearing capacity requirements. However, it is necessary to ensure tha...

Abstract

The invention relates to a three-dimensional energy-consumption shock-absorption device, which overcomes the defects of poor overturning resistance capability and difficult realization of vertical damping of the existing three-dimensional shock-absorption device. The three-dimensional energy-consumption shock-absorption device consists of an upper part and a lower part, wherein the lower part of the three-dimensional energy-consumption shock-absorption device is a common use horizontal rubber support seat, the upper part mainly consists of a polymer damping material, a sandwich layer steel plate, a lead damping rod and an auxiliary butterfly spring, the upper part and the lower part are in rigidity connection through two connecting plates, the polymer damping material, the sandwich layer steel plate, the damping rod and an external guide force transfer sleeve barrel form a vertical main shock absorption system which is combined with the butterfly spring, the vertical main shock absorption system and the butterfly spring are connected in parallel on a core post in the center of the connecting plates for simultaneously carrying the vertical load of the upper part, the carrying capability is higher, the vertical damping is great, the damping can be easily realized, and the energy consumption capability is strong. The polymer material is restricted by the sandwich layer steel plate in the transverse direction, the compression modulus is greatly improved, and the overturning caused by structure and earthquake nondeterminacy can be stably resisted. The invention has a scientificand reasonable structure, and has good horizontal and vertical rigidity and damping energy-consumption capability, good anti-bending capability, good stability, convenient processing and stable performance.

Description

technical field [0001] The invention relates to a shock absorber used in the field of civil engineering, in particular to a three-dimensional energy dissipation shock absorber with reasonable stiffness and strong damping and energy dissipation capacity. Background technique [0002] Earthquakes usually bring huge casualties and economic losses to human beings, and people are constantly looking for effective methods that can resist or weaken earthquake disasters. At present, three major structural vibration control technologies, passive control, semi-active control and active control, have been formed in the field of civil engineering. Among them, seismic isolation technology is the most mature and has been included in the norms of major earthquake countries in the world. These technologies are mainly based on horizontal earthquake control. However, earthquake engineering studies have shown that earthquakes are multi-dimensional. For some important structures, spaces, large ...
