Abstract
The utility model relates to a shock isolation support for buildings and structures, which is arranged between the bottom of a building and foundation substructure. The shock isolation support is composed of an upper and a lower spherical surface seat bodies which are symmetrically arranged and a rigidity spherical body arranged in the two spherical surface seat bodies. The utility model can carry out isolation to an earthquake effect at a house substructure place, and the earthquake effect is generated to a house by an earthquake motion. A destructive force born by the house is reduced. The utility model is suitable for be used in the buildings and the structures with various substructure forms.
Description
The utility model relates to a kind of building earthquake isolating equipment.What be particularly related to is a kind of shock isolating pedestal between building basal part and the foundation that is installed in.
The existing shock isolating pedestal that is installed between building basal part and the foundation is a lot, the common laminated rubber bases that forms as being superimposed, the helical spring bearing that constitutes by round metal cylindricality helical spring, be common sliding support of constituting of sliding material or the like by sand cushion, graphite linings, corrosion resistant plate and polyacetal resin by TR thin rubber plate and steel sheet, the shortcoming of these shock isolating pedestals or to the requirement height of material, to manufacture difficulty big, or the cost costliness, and do not possess automatically reset performance.
The purpose of this utility model provides a kind of simple in structure, shock isolating pedestal of manufacturing easily and having good reseting performance voluntarily.
The vibration isolating suspension of realizing the utility model purpose is made of upper and lower two symmetrically arranged sphere pedestals and the rigid spheres that is arranged in the described two sphere pedestals.Its shock insulation, the operating principle that resets are: of the present utility modelly go up that the sphere pedestal is affixed bottom building, lower peripheral surface pedestal and foundation be affixed.The number of the shock isolating pedestal of required setting can be determined according to the scale of construction, load size and the structural plan deployment scenarios thereof in house.Under static situation, rigid spheres is positioned at the pedestal lowest part, when earthquake takes place, the spheroid of this shock isolating pedestal is subjected to the effect of earthquake level and vertical force to produce rolling along spheric seating, mutual conversion by its kinetic energy and potential energy, make building be translation lentamente and move back and forth, and the reciprocation period that can make the house prolongs 5～7 times than period of motion in the house on conventional fixed basis with low frequency.Along with the raising of frequency of seismic wave, the house, top is by being inactive state.Simultaneously, because rigid spheres has the vertical applied force component in motion process, so this shock isolating pedestal has the energy dissipating of isolation effect equally to vertical geological process.When the earthquake effect stops, the rigidity spheroid can automatically revert to ball seat lowest part this initial position before the earthquake again, promptly realizes building is automatically reset.
The utility model is just isolated taphrogeny at the house foundation place " geological process " that the house produces, what make that the house is subjected to reduces greatly because of seimic destructive power, according to test, to being located in the house of 8～10 ° of earthquake zonies, after being provided with this shock isolating pedestal, the suffered geological process in house only shows as 5～6 °, and this has just fundamentally realized the requirement of " shaking not bad greatly " in house, high earthquake intensity area.Build the house and all can not be subjected to existing traditional earthquake resistant design code method predetermined restricted thereby can remove many restrictive conditions, especially highly seismic region in traditional seismic design, " forbidden zone " of the design of house, earthquake zone do not existed.Building and structure that this earthquake bearing is fit to various base forms such as insulated column basis, strip foundation, ring foundation, slab foundation use.
Provide embodiment below in conjunction with accompanying drawing:
Fig. 1 structural representation of the present utility model
The vertical view of Fig. 2 Fig. 1
Fig. 3 schematic diagram of installing and using of the present utility model
Referring to Fig. 1～3, the utility model is made of identical last sphere pedestal 1, lower peripheral surface pedestal 2 of two symmetrically arranged equal and opposite in directions, radius of curvature and the rigid spheres 3 that is arranged in the sphere pedestal 1,2.Last sphere pedestal 1 can be affixed with the closed collar tie beam 5 of building with bolt 4, and 2 available the same manners of lower peripheral surface seat are installed on the foundation 6.
Claims (1)
1, a kind of can be from the shock isolating pedestal of horizontal reset, it is characterized in that described shock isolating pedestal is made of upper and lower two symmetrically arranged sphere pedestals and the rigid spheres that is arranged in the described two sphere pedestals.
