Description
Technical field
The present invention relates to the safety assurance of isolation structure, especially belong to the restraint device of isolation structure layer extreme displacement in the isolation structure.
Background technology
Seismic isolation technology is the isolation structure layer to be set to intercept the seismic energy transmission between the superstructure of engineering structures and substructure, reduces the engineering structures earthquake response, alleviates a kind of new technology of seismic damage.In theory, the isolating affection of isolation structure depends on the rigidity of isolation structure layer, and rigidity is more little, and isolating affection is good more, and is corresponding, and this moment, the displacement of isolation structure layer was also big more.Therefore, give full play to the isolation structure isolating affection, reach optimum utility, the isolation structure layer is stablized under guaranteeing small earthquake (meeting earthquake frequently), should fully reduce the isolation structure stiffness layer.Yet; Identical two secondary earthquakes useless in the world; The isolation structure stiffness layer also is nonlinear change with earthquake energy size, isolation structure layer displacement difference under this just feasible actual each time geological process, and the isolation structure layer displacement that the theoretical ground seismic wave function of each bar analyzes is also different.So; From theory and practice, do not allow to consider that the isolation structure layer reaches its theoretical limit displacement under the violent earthquake (rarely occurred earthquake); The displacement of shock insulation deck is less than 1/2 of its tolerance limit displacement, with plan safety when generally considering violent earthquake (rarely occurred earthquake) in the engineering reality.
Summary of the invention
The object of the present invention is to provide a kind of isolation structure layer extreme displacement restraint device; Make people can relievedly reduce isolation structure layer isolated component rigidity; Give full play to the isolated component isolating affection, isolated component destroys and causes the havoc of isolation structure when preventing special violent earthquake simultaneously.
The technical scheme that the present invention taked is: it is meant the extreme displacement restraint device and at least one extreme displacement restraint device of vertically arranging of at least one lateral arrangement of packing in the isolation structure layer between superstructure upper beam and substructure underbeam; And the gap of this extreme displacement restraint device inside is less than or equal to the extreme displacement of isolation structure layer more than or equal to the extreme displacement of 1/2 isolation structure layer.
Beneficial effect of the present invention is: 1, isolation structure layer extreme displacement restraint device of the present invention; Make people when design and construction; The rigidity of isolation structure layer isolated component in the minimizing isolation structure that can be relieved is to reach the purpose of giving full play to the isolated component isolating affection; 2, isolation structure layer extreme displacement restraint device of the present invention, isolated component destroys and the havoc of the isolation structure that causes in the time of can preventing violent earthquake and special violent earthquake.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Be illustrated in figure 1 as principle of the invention figure; Fig. 2 is the schematic diagram of overlooking of Fig. 1; But knowledge capital is invented the extreme displacement restraint device 6 and at least one extreme displacement restraint device of vertically arranging 6 that it is meant at least one lateral arrangement of packing in the isolation structure layer 1 between superstructure 4 upper beams 2 and substructure 5 underbeams 3 from figure; And the gap of these extreme displacement restraint device 6 inside is less than or equal to the extreme displacement of isolation structure layer 1 more than or equal to the extreme displacement of 1/2 isolation structure layer 1.
Extreme displacement restraint device 6 of the present invention is meant on upper beam 2 two upper beam brackets 21 is set; While is provided with a underbeam bracket 31 on the underbeam 3 of the middle correspondence position of two upper beam brackets 21; Be shaped on upper beam magnet A22 and upper beam magnet B23 on the upper beam bracket 21 respectively, magnet A22 and upper beam magnet B23 corresponding underbeam magnet A32 and underbeam magnet B33 are shaped on respectively on the underbeam bracket 31 and put the beams in place; Upper beam magnet A22 and underbeam magnet A32, upper beam magnet B23 and underbeam magnet B33 have same magnetic; And the gap between upper beam bracket 21 and the underbeam bracket 31 is less than or equal to the extreme displacement of isolation structure layer 1 more than or equal to the extreme displacement of 1/2 isolation structure layer 1.。
In the concrete design and construction process, can the gap design between upper beam bracket 21 of the present invention and the underbeam bracket 31 be become to equal the extreme displacement of isolation structure layer 1, to reach best effect.
Upper beam magnet A22 of the present invention, upper beam magnet B23, underbeam magnet A32 and underbeam magnet B33 are made by permanent magnet, conventional electromagnet or superconducting electromagnet.
Extreme displacement restraint device 6 of the present invention is mounted in corner positions, the peripheral position of engineering structures or when earthquake, displacement is reflected relatively more responsive position, and concrete quantity and position of installing can be set according to the concrete condition of engineering structures.
Operating principle of the present invention is: when earthquake takes place; Owing between superstructure 4 and the substructure 5 relative displacement takes place; Be installed in put the beams in place 2 with underbeam 3 on upper beam bracket 21 and underbeam bracket 31 can produce relatively near motion because the corresponding surface of upper beam bracket 21 and underbeam bracket 31 is provided with the upper beam magnet A22 and the underbeam magnet A32 of same pole, when upper beam bracket 21 is moved near underbeam bracket 31 with superstructure; The upper beam magnet A22 of same pole and underbeam magnet B32 will produce repulsive force; Upper beam magnet A22 and underbeam magnet A32 the closer to, the repulsive force that then produces is big more, electromagnetism same sex repulsion has guaranteed can not bump between the bracket up and down; Simultaneously; In view of when design upper beam bracket 21 and underbeam bracket 31 between the gap be not more than the extreme displacement of isolation structure layer 1, therefore, this device can guarantee that the displacement of isolation structure layer 1 is no more than extreme displacement and can bump between the bracket up and down.Earthquake isolating equipment can play a role safely when so just having guaranteed the earthquake generation.
