The invention relates to a horizontal shearing locking shock isolation device. The horizontal shearing locking shock isolation device comprises an upper body, hexagon socket cap screws, shear pins, a middle body, hexagon bolts, flat washers, hexagon socket cap screws, a lower body, a rubber rod, a sleeve and a cushion plate. The upper body and the upper structure are fixed through the hexagon bolts, the shear pins penetrate through the upper body and the middle body to be used for bearing horizontal shear force, the middle body and the rubber rod are connected, pre-tension force is applied to the middle body through the hexagon socket cap screws, the rubber rod is in a pre-tensioned state, and the sleeve limits horizontal motion of the middle body. Furthermore, the cushion plate and the rubber rod are bound through the vulcanization technology, pre-tension force is generated after the hexagon socket cap screws are tightened, the rubber rod is in a tensioned state through the pre-tension force, and therefore the purpose that the lower half portions of the shear pins rebound downwards after the shear pins are sheared off, and normal hysteresis of a rubber support is not affected is achieved.
Description
Technical field
The invention belongs to building structure damper field, particularly a kind of 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 a kind of horizontal shear locking earthquake isolating equipment, for the shock design to Seismic Isolation of Isolation Layer displacement Sensitive Buildings structure, make nuclear power station isolation structure under small earthquakes effect, geological process is resisted by superstructure, earthquake isolating equipment is in blocking, unlock when large shake carrys out interim blocking device, shock isolating pedestal enters work, ensured the safety of superstructure to distortion earthquake energy by the level of shock isolating pedestal, and shear pin is cut off rear the latter half can resilience downwards, do not affect the normal hysteresis of neoprene bearing.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of horizontal shear locking earthquake isolating equipment, comprises upper body, hexagon socket cap head screw, shear pin, intermediate, hexagon-headed bolt, plain washer, hexagon socket cap head screw, lower body, rubber bar, sleeve, backing plate; Described upper body is fixed by hexagon-headed bolt and superstructure, shear-pin is used for bearing horizontal shear force through upper body and intermediate, intermediate is connected with rubber bar, applying pretension by hexagon socket cap head screw to intermediate makes rubber bar be in pre-tension state, the motion of sleeve restriction intermediate levels.
Further, described backing plate and rubber bar bonding is made by sulfuration process, produce a pretension after tightening hexagon socket cap head screw, pretension makes rubber bar be in tension state thus realizes shear pin to be cut off the resilience downwards of rear the latter half, does not affect the object of the normal hysteresis of neoprene bearing.
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) shear pin can be realized and cut off the resilience downwards of rear the latter half, not affect the object of the normal hysteresis of neoprene bearing.
3) blocking device has the feature of anti-pulling simultaneously, prevents the vertical deformation that structure is excessive.
4) after blocking device unblock, double threaded screw is cut off, and upper and lower sleeve does not damage, and can reuse after shake.
