Description
Technical field
The invention belongs to building aseismicity technical field, and in particular to a kind of shock insulation limit protection device.
Background technology
With continuing to develop for seismic isolation technology, the state such as the U.S., Japan, China and Italy widely uses basis in engineering
Shock insulation, the series connection technology such as shock insulation and Interlayer seismic isolation, form substantial amounts of isolation structure.Isolation structure generally uses rubber vibration isolation branch
Seat forms Seismic Isolation of Isolation Layer, and extending structure natural vibration period, increase damping reduces input of the seismic energy to superstructure, ties top
Translation occurs for structure without damaging.Therefore, the effect of shock insulation rubber bearing is that larger displacement is produced under geological process, then
Power consumption, it is ensured that superstructure safety.But, rubber earthquake isolation support limited location requirement, once shock isolating pedestal occur in earthquake compared with
Big displacement and more than limit value, the problem of toppling can be caused, then cause overall structure to collapse.Meanwhile, domestic and international researcher
Carried out numerous studies to Chi-chi earthquake, research find Chi-chi earthquake there is hanging-wall effect, it is beam-shaping effect, larger
Velocity pulse and dfisplacement pulse etc..These effects are produced to macrocyclic isolation structure and adversely affected very much, cause shock insulation branch
Larger displacement occurs for seat, can seriously cause shock isolating pedestal to exceed limit value and problem of toppling.Therefore, the limit of shock isolating pedestal is solved
Position problem is extremely urgent.
At present, some existing shock isolating pedestal stopping means cost height, complex process, be difficult to popularize and apply；Also one
A little shock isolating pedestal stopping means meet simple and convenient, the cheap requirement of construction, but protective is not enough, easily destroys
And cause shock isolating pedestal also to occur problem.

Energy bloom, consume energy spacing bloom, spacing bloom are fixed on fixed bloom, and the described spacing bloom of power consumption hangs down with fixed bloom
It is straight fixed, the interchangeable both sides for being located at the spacing bloom that consumes energy of described power consumption bloom and spacing bloom position, and limited with power consumption
Position bloom is in degree angle.
The width of described fixation bloom is power consumption bloom, the summation of the spacing bloom of power consumption and spacing bloom width.
The total height of described mild steel damper subtracts shock isolating pedestal upper junction plate height for the total height of shock isolating pedestal
Half.
The width of the one piece of bloom in bottom in described mild steel damper is 150mm -300mm, highly high for shock isolating pedestal
The 1/3 of degree, length is identical with the length of shock isolating pedestal.
The width of three blooms in top in described mild steel damper is 50mm -100mm, is highly mild steel damper
Total height subtract the height of bottom bloom, length is identical with the length of shock isolating pedestal.
Described mild steel damper selects Q345D steel.
Described junction steel plate and pre-embedded steel slab is that width is that 250mm -400mm, thickness are 20mm -30mm, length
And model Q345 identical with the length of shock isolating pedestal cuboid bloom.
The present invention can avoid shock isolating pedestal occur larger displacement and more than limit value, and can mass industrialized production every
Shake protector.The device hits spacing mild steel damper top three long successively when shock isolating pedestal displacement reaches limit value soon
Cube bloom, plays spacing and power consumption double action, prevents shock isolating pedestal from toppling and destroying.Therefore, with prior art phase
Than the present invention has not only easy construction, safe, and according to the size of shock isolating pedestal, can this is spacing with Aided design
Mild steel damper, so that the production of industrial mass, reduces cost.It is three long by the spacing mild steel damper top
Cube bloom consumes energy successively, so as to play effective spacing and protection to shock isolating pedestal.
