The technical scheme of this patent is described in more detail with reference to embodiment.
Refer to Fig. 1-4, a kind of spring vibration isolation structure for low layer masonry structure building, including reinforced concrete foundation
Collar tie beam 2；Reinforced concrete foundation collar tie beam 2 is supported by reinforced concrete structural column in foundation wall 4；The reinforced concrete foundation
The top of collar tie beam 2 sets the reinforced concrete supporting beam 1 supported by armored concrete Protection Pier 5, the steel of the lower section of reinforced concrete supporting beam 1
The upside of reinforced concrete foundation ring girder 2 is provided with isolation mounting 3；Isolation mounting 3 is spring vibration isolation device；The isolation mounting 3 with
Reinforced concrete foundation collar tie beam is attached by pre-embedded bolt；The size of reinforced concrete foundation collar tie beam 2 is 370X240
mm；The bottom of isolation mounting 3 sets constructional column 370X500 mm, construction column length 600mm；The size of reinforced concrete supporting beam 1
For 240X450mm；The size of armored concrete Protection Pier 5 is 370X500mm；The top of armored concrete Protection Pier 5 is set
3cm rubber blankets, apart from the bottom 3cm of reinforced concrete supporting beam 1；Distance should be not less than 80cm to the apex distance of isolation mounting 3 from the ground.
When not considering the situation of foundation failure, the eaerthquake damage of low layer brick masonry structure building is mainly due to Earth Surface During Earthquakes
Horizontal acceleration is excessive during motion, and because house is smaller natural vibration period, its overall acceleration, which can be considered, is equal to ground acceleration,
The horizontal inertial force in house is larger, and greater level shearing is produced in wall causes wall crazing, between some weak parts such as window
Wall easily forms intersection inclined crack, and the utility model technology, will by setting vibration insulation between foundation structure and superstructure
Ground level vibration is isolated so that the acceleration of incoming superstructure significantly weakens, and is dissipated earthquake motion by damper
The energy of input is from and ensureing superstructure and be not damaged.It is infrastructure structure below isolation mounting, reinforced concrete foundation
Collar tie beam apex distance ground level is 0.58m, and basis can use pile foundation or bar base depending on foundation condition, and infrastructure structure can be considered and ground
The firm body that base soil is in close contact, in geological process, its displacement is equal to place displacement and acceleration with acceleration.Seismic Isolation of Isolation Layer
Single vibration isolator horizontal rigidity is about 4000 ~ 8000KN/m, pre-embedded steel slab, vibration isolator bottom and top on foundation ring girder and joist
Vibration isolator and foundation ring girder and joist are connected by weld seam.After house bottom sets vibration isolator, the overall natural period prolongs
It is long, and in vibration insulation formation rigidity weak floor, geological process, energy is by vibration isolator absorbing and filtering caused by earthquake motion, and passes through
Its inside damper dissipate after, only fraction is delivered in upper building, so as to reduce the generation of earthquake, it is ensured that life and
Property safety；
Using Qingdao rural area from two layers of half houses owed by a citizen of lid（One layer of top loft）, floor height 3m, loft floor height highest point
For 3.833m.Outer wall thick 370mm, interior wall thickness 240mm, the long 12m in house, wide 11.8m, vibration insulation arrange 38 vibration isolators altogether, often
Platform vibration isolator horizontal rigidity is 6200KN/m, and vertical rigidity is 7800 KN/m.Room plane figure and vibration isolator arrangement are said as follows
Bright book accompanying drawing 4.
In order to investigate performance of the house in earthquake, it is entered from universal architecture finite element analysis software SAP2000
Row is modeled and calculate and analyzes, and wall and floor are simulated using thin shell element, and material property is derived from existing national standard《Masonry knot
Structure design specification》, beam simulated using frame unit, and vibration isolator uses linearly connected unit simulation, be concerned only with during calculating horizontal X to
The free degree, calculate operating mode and select corralit, In The Area of Qingdao comprising static load analysis and linear time history analysis, seismic wave
Fortification intensity is 7 degree of 0.1g, and seismic wave peak accelerator is adjusted to 240gal. slightly larger than earthquake resistant code requirement（220gal）.For
The performance capabilities of contrast shock insulation front-end geometry, calculates two models, and A is isolation structure, B be non-shock insulation conventional structure, leads
Want index result of calculation as follows：
Table A Structures under Earthquake response value
Project model A Model B ratios（B/A）
X is to mode cycle 0.55s 0.073s 0.133
Top acceleration 73gal 206gal 2.822
Bearing relative displacement 0.85mm 0mm 0
Base shear 170KN 1247KN 7.335
Finite element analysis results show：1st, using the low layer house owed by a citizen of isolation scheme, than the low layer house owed by a citizen of non-isolation scheme
Earthquake performance capabilities is more excellent, and the seismic shear of substrate can be greatly reduced, and reduces structural damage degree, it is ensured that structure is pacified
Entirely；2nd, horizontal acceleration is relatively low at vibration isolation house floor, and the security of its property such as furniture, suspension member also more has guarantor inside house
Card.
