The steel plate 9 and the lower body 7 are connected through the high-strength bolts 5&6. The device is left-right symmetric. After the locking device is assembled, the upper body and the lower body produce horizontal displacement under the action of earthquakes, the inner body 4 transmits force to the shear pins 3 which are stressed at the moment to provide a horizontal locking function under the action of small earthquakes, the shear pins 3 are sheared and fractured when large earthquakes occur, a rubber support begins to play a role to move horizontally to consume energy, the inner body 4 can be subjected to vertical displacement by the pre-compression of the rubber pad 8, and accordingly blocking of movements of the inner body 4 when the support moves back and forth is avoided.
Description
Technical field
The invention belongs to building structure damper field, particularly combined type precompressed automatic rebounding type horizontal shear blocking device.
Background technology
Nuclear power plant structure is as a kind of special construction system, and earthquake is one of biggest threat of its safety.When suffering earthquake, all structure, system, parts and the equipment of nuclear power station is almost excited simultaneously, the integrity of the integrality of entail dangers to structure and equipment, component function.
The life and property loss that special violent earthquake causes is startling, if special violent earthquake occurs in nuclear power station region, the consequence caused will be catastrophic.Within 1999, Chi-Chi Earthquake causes Taiwan first nuclear power station 2 compressor emergency shutdowns; Japan Niigata earthquake in 2007; cause Bai Qi to cut plumage nuclear power station to close; there are 9.0 grades of violent earthquakes in coastal waters, Miyagi Prefecture, Japan in 2011; Fukushima nuclear power station 4 units are caused to be blasted; cause serious nuclear leakage accident, the economy caused, environmental loss are difficult to estimate.
Current nuclear power station structure design is still based on traditional anti-seismic technology, emerging earthquake isolation technology is seriously delayed at the research and apply of nuclear power station construction applications, up to now in the whole world all commercial off-the-shelfs nuclear power plant, two are only had to employ base isolation technology.Within 1977, first rubber isolator is used for the Koeberg nuclear power station in South Africa, within 1984, is applied to the Cruas nuclear power station of France.Shock insulation effectively can reduce the acceleration earthquake reaction of nuclear island, but the over-large displacement of Seismic Isolation of Isolation Layer may cause turnover nuclear island line break simultaneously, easily causes secondary destruction.This becomes the key issue that restriction seismic isolation technology is applied in nuclear power structure.
Summary of the invention
Consider the limitation of existing technology, the object of this invention is to provide combined type precompressed automatic rebounding type horizontal shear blocking device, for the shock design to Seismic Isolation of Isolation Layer displacement Sensitive Buildings structure, make nuclear power station isolation structure under small earthquakes effect, resist geological process by superstructure, earthquake isolating equipment is in blocking, unlocks when large shake carrys out interim blocking device, shock isolating pedestal enters work, is ensured the safety of superstructure by the level of shock isolating pedestal to distortion earthquake energy.
For achieving the above object, the technical solution used in the present invention is as follows:
Combined type precompressed automatic rebounding type horizontal shear blocking device, comprises upper body inner ring, upper body outer shroud, shear pin, interior body, high-strength bolt, lower body, rubber pad, steel plate; Described upper body inner ring and upper body outer shroud are by being welded to connect; Affiliated upper body inner ring is connected by shear pin with interior body; Described interior body is connected by high-strength bolt with lower body; Described rubber pad and lower body are fixed by binding material bonding; Affiliated steel plate is connected by high-strength bolt with lower body, and device is symmetrical.
Further, the end of described shear pin is provided with screw thread, upper body inner ring and interior body is fixed by tightening screw thread.
Compared with prior art, the present invention has following outstanding advantage:
1), in solving, under small earthquake effect, the displacement of shock insulation nuclear power station Seismic Isolation of Isolation Layer is excessive to be caused line fracture thus causes the problem of secondary destruction, and blocking device unlocks under large shake effect, and shock isolating pedestal enters consumption in operation seismic energy.
2) by regulating the material of high-strength shear key, quantity, size and weak section diameter to change the lock-in threshold of blocking device, thus designing requirement is reached.
3) rubber pad that blocking device is connected with lower body has rebound characteristics, when high-strength bolt junction steel plate, lower body and interior body, and rubber pad precompressed, after shear pin is cut off, rubber resilience, interior body produces vertical displacement, avoids the obstruction to upper body inner ring movement when bearing moves around.
4) after blocking device unblock, shear pin is cut off, and upper body and lower body all do not damage, and can reuse after shake.
