Description
Technical field
The utility model belongs to technical field of structural engineering, is specially a kind of iris type level to the locking shock isolating pedestal.
Background technology
Earthquake is one of serious natural calamity.According to statistics, in the world because the quantity of the building structure that earthquake attack to destroy, far away more than the wind building structure quantity that the natural calamity that waits other destroys of shaking.The antidetonation of building structure is theoretical also constantly developed with seismic measures, and the construction work personnel study to transform to building structure and make it can resist earthquake disaster, minimizing casualties and economic loss to have experienced following differentiation: (1) rigid structures system; (2) flexible structural system; (3) flexible bottom layer structural system; (4) ductility structural system; (5) isolation structure system.At present, the use of earthquake isolating equipment makes seismic design of structures develop into " disappearing " by " resisting ", is representing the latest development direction of structural seismic technology.At present, the most frequently used shock-resistant and energy-dissipating technology is that the earthquake isolating equipment of mainly being made up of shock isolating pedestal (also having document to be called the shock insulation pad) and damper is set.
But, earthquake isolating equipment only is set can brings obvious defects later, no matter mainly be the earthquake size that takes place, its basic displacement all might cause line break, it is many unfavorable that this can bring operation, maintenance etc.Particularly for nuclear power plant, in case important line break, even can bring out the nuclear safety accident.In Chinese utility model patent " nuclear power plant's nuclear island architecture basics earthquake isolating equipment of band blocking function " (application number 200920167910.3); Consideration is being provided with the shock insulation pad simultaneously; The level that has proposed the shock insulation pad is set to initial blocking device originally; Make shock isolating pedestal only under the super design reference seismic events, just bringing into play its isolating affection; Make whole nuclear island structure when the super design reference earthquake, also can be in the structural safety state, and can reduce the risk that the big displacement in basis is caused to greatest extent.This utility model has adopted the structural configuration of shear-type, is surmounting under the design basis earthquake incident, and the screw rod of this device can be cut off, thereby has removed the locking of the initial level direction of shock insulation pad.But because screw rod is near excessively apart from the shock insulation pad in this utility model, the screw rod of the disconnection that impelling goes out when cutting off or other parts may damage the shock insulation pad, influence the work of shock insulation pad.
Summary of the invention
The purpose of the utility model is to provide a kind of iris type level to the locking shock isolating pedestal, under the prerequisite that does not change superstructure, can significantly improve the anti-seismic performance of structure, and the line break risk that can avoid the big displacement in basis to cause to a great extent.
The technical scheme of the utility model is following: a kind of iris type level comprises that to the locking shock isolating pedestal concrete bearing, shock isolating pedestal, space enclosing structure, resistance advance steel plate, driven rod, dividing plate and superstructure base plate; Shock isolating pedestal is positioned on the concrete bearing, and the two connects through joint bar or bolt; The placement of setting all around that steel plate is pressed close to shock isolating pedestal is advanced in four resistances, and its base is articulated in concrete bearing; Space enclosing structure is positioned at around the shock isolating pedestal, is the rectangle steel tendon concrete structure of closure, with the common arrangement of reinforcement cast of concrete bearing, the plugboard trough that its four sides respectively has an opening to make progress; Four dividing plates vertically insert in four plugboard troughs at space enclosing structure four sides, and to advance steel plate corresponding with resistance; Four driven rods connect corresponding dividing plate and advance steel plate with resistance; Shock isolating pedestal is connected through joint bar or bolt with the superstructure base plate.
There is a brittle zone at said dividing plate middle part, and the brittle zone is connected through manomelia with on every side diaphragm body, is provided with in the middle part of the brittle zone to cut with scissors and encircles.
Respectively there is the cavity of a horizontal direction at said space enclosing structure four sides, and it is hinged that steel plate is advanced in driven rod one end and resistance, and the other end is connected with the hinge ring of dividing plate brittle zone through the cavity of space enclosing structure horizontal direction.
Said four dividing plates vertically insert in four plugboard troughs at space enclosing structure four sides, fix with latex cement or epoxy resin.
Said driven rod is processed by common solid construction steel, and diameter is 6cm.
Said resistance is advanced steel plate and is processed by general structural steel, and thickness is 2cm, and the center has a hinge ring.
Said shock isolating pedestal is the lead core stacking rubber earthquake isolation support of square sectional, and the length of side is 20cm, and thickness is 80cm, is formed by 100 layers of rubber layer and 100 layers of steel plate arranged alternate, and the centre has vertical through hole, and the circular lead for retractable pencil rod of diameter 5cm vertically inserts wherein.
Said concrete bearing is a reinforced concrete structure, is seated on the ground of building.
Said superstructure base plate is a steel concrete raft plate.
The remarkable result of the utility model is:
(1) " steel plate-driven rod-dividing plate is advanced in resistance " forms initial level to shock isolating pedestal to locking, promptly when original state, shock isolating pedestal in level to moving.When being no more than antidetonation benchmark acceleration, shock isolating pedestal only plays the effect of common bearing, can not cause breaking of pipeline because of big basic displacement;
(2) after the brittle zone of dividing plate breaks, still be hinged on the driven rod, can not cause destruction because of flying of brittle zone to the peripheral region;
(3) effect that steel plate plays the protection shock isolating pedestal is advanced in resistance, prevents that the external world from flying thing shock isolating pedestal is damaged;
(4) around shock isolating pedestal, an initial level that is formed by " steel plate-driven rod-dividing plate is advanced in resistance " is respectively arranged to locking; After the initial level lockout of a horizontal direction; If the earthquake acceleration of another horizontal direction does not surpass benchmark antidetonation acceleration, then the locking of the initial level of this horizontal direction still can work on;
(5) driven rod only can transmit pressure in this device; So same direction only has a clapboard stress; Thereby avoided the reciprocal effect of two dividing plates of same direction; Be convenient to confirming of dividing plate brittle zone intensity, and when a dividing plate caused the brittle zone to destroy because of pressurized after, another piece dividing plate possibly not go to pot still;
This device does not need the support of the external energy or signal, and easy to maintenance, only needs ruined dividing plate is taken out from the slot of space enclosing structure, changes new dividing plate and with it and driven rod is hinged gets final product.
