the specific embodiment:
The utility model is that one can earthquake-resistant real estate building, comprise main building 1, as shown in Fig. 3-Fig. 7, it is characterized in that: below earth's surface, the bottom of the floor of main building 1 has double-layered ground structure, be first floor ground 5 and second layer ground 3, second layer ground 3 is arranged on the top of first floor ground 5; Between first floor ground 5 and second layer ground 3, be provided with intermediate isolating layer 4.
Below earth's surface, the double-layered ground superstructure of main building 1 floor bottom has shear wall structure basement 6.
Four jiaos, the floor of main building 1 should be reinforced rigid structures, doubles reinforcing bar arranging density.
Principle of the present utility model is as follows:
double-layered ground structure
First floor pouring reinforced concrete ground, must be foundation with addressing ground geological condition history according to the vertical height of floor, determines the first floor foundation structure degree of depth, height and the width.Be that first floor ground fracture also has the second layer ground antidetonation of setting up defences in other words, in other words if second layer ground safety firmly, floor general safety does not just have large problem.
Because first floor foundation structure is being protected second layer foundation structure, to move all comprehensive function power such as the elastic force of the seismic wave that dissipated in " system " moving motion to floor, inertia force, flutter power.So little many of seismic wave energy that second layer ground is accepted than first floor ground, therefore floor has obtained protection in earthquake elastic wave.
Intermediate isolating layer structure, is the separation layer between first floor ground and second layer ground, is referred to as intermediate isolating layer.Its meaning is to allow floor entirety and " the earth isolation ", and similar floor " floats over " Earth Surface, floats over sea as the steamer in ocean.What they were different is, when building " floats over " apparent motion of the earth, friction factor is large, and that steamer floats over the surface operation friction factor in sea is little, identical something in common not again that Here it is, so intermediate isolating layer structure arrived the cushioning effect to seismic wave conduction second layer ground.
first floor foundation structure
6-10 or the design of 10-30 floor foundation structure, according to general layout plan engineering layout, first floor ground and indoor load bearing wall are structure as a whole altogether.
intermediate isolating layer
Intermediate isolating layer requires to accomplish identical with first floor, second layer ground geometric area, require smooth, friction factor is little, high-storey selection 2mm corrosion resistant plate, general floor selects 2-4mm plastic plate to make intermediate isolating layer.
second layer foundation structure
The same pouring construction of second layer foundation structure and floor basement, selects reinforcing bar material and reinforcing bar arranging density and first floor to double reinforcing bar arranging density foundation structure identical.
basement space
Following basement space outer, earth's surface is to double-layered ground, requires the extruding of filling sandy soil, with set up defences severe earthquake elastic wave to high level acutely rock, crooked.
four jiaos, floor
Floor four-corner structure is floor body of wall flex point, and its closes chain to the safety of two sides body of wall, is the set up defences main points of antidetonation of high-storey building engineering.
Require four jiaos, floor and the same pouring construction in body of wall two sides and second layer foundation structure basis, and accomplish can not be because of the moulding of building ventilating duct or washroom or floor, and protrude or the position of four jiaos, recessed floor, affect the vertical rigidity structure of floor.
aseismic analysis
In the time that seismic energy collides or breaks through the earth's crust, subsurface rock layer is because being subject to intense impact, produce vibration elastic ripple with the propagation as the billow of radial similar ocean, it is exactly this ripple, because by the difference of ground physical property, and the speed of propagating is not identical yet, not identical speed energy is greatly destructive to real estate, and this elastic wave is referred to as seismic wave.
When little energy level earthquake occurs, when elastic wave kinetic energy acts on floor first floor foundation structure, because intermediate isolating layer cushioning effect, the elastic wave energy that dissipated, floor slightly trembles, and this earthquake elastic wave energy is roughly in 4-5 level.
When the earthquake of moderate level attacks, crowd cuts down as the little bamboo of climbing up in rivers torrent, earthquake elastic wave kinetic energy conducts in the time of vertical high-storey building, be greater than the kinetic energy of ground surface, scale-up elastic force, inertia force, flutter power rock floor, this moment, most undefended buildings collapse down at the sound.In other words, when seismic wave kinetic energy acts on first floor foundation structure, because second layer ground floor rocks, weakened earthquake elastic wave kinetic energy, 7.1 grades of earthquake kinetic energy are only similar in appearance to approximately 6 grades of geological process power thus.
When severe level earthquake surprise attack, earthquake elastic wave kinetic energy is equal to or greater than real estate gross pressure energy, and similarly seismic wave kinetic energy lifts real estate building.The elastic force of seismic wave, inertia force, flutter power are to floor shake vigorously thus, but because floor double-layered ground and seismic wave elastic force energy are not very stiff and demanding antagonism, but to move " system " moving active force seismic wave combined stress that dissipated, the kinetic energy that has slowed down seismic wave acutely rocks vertical high-storey, Here it is double-layered ground, the result that first floor and the second layer and intermediate isolating layer act on each other.As Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, in earthquake, all to move the embodiment of braking, stand the test of earthquake elastic wave.
Principle of the present utility model is done to simulated experiment below:
Fig. 1 (a) is by the high diameter 200mm of 60mm cask, is welded on square iron plate upper as chassis, and two A, B glass are placed in the inside, and A glass bottom is firmly adhered to chassis.B glass bottom lies against chassis, and is crowded with sandy soil in drum.
Experimental model 1:
With O point two hammers or three hammers on common hand hammer bang chassis, similar earthquake elastic wave releases energy to the earth's crust.The A glass of strong bond breaks.There is no bonding complete the rocking of B glass, rocking of similar roly-poly type in other words.
Fig. 1 (b) is fixing two bolts that mechanical performance is identical with on Fig. 1 (a) phase same iron plate, and upper bolt adds spring washer and is anchored on iron plate.Lower bolt pine is connected in iron plate.
Experimental model 2:
With O point two hammers or three hammers of the upper bolt of common hand hammer bang, similar earthquake elastic wave releases energy to the earth's crust.Arrow represents the direction of iron hammer shearing force effect, and bolt is fracture completely under gravity shear action.
Lower bolt is pine connection because diameter is less than iron plate aperture many, hammer into shape with O point two hammers or three of the iron hammer bang bolt of equivalent weight, similar earthquake elastic wave releases energy to the earth's crust, arrow represents the direction of iron hammer shearing force effect, under Action of Gravity Field, bolt right-hand member produces active force downwards, and bolt left end upwards produces active force, has not only disperseed iron hammer active force, and impelling screw rod resilience in iron plate circular hole, the shearing force bolt of the iron hammer that therefore dissipated is completely harmless.
By little experimental model, similar direct observation earthquake elastic wave releases energy to the earth's crust, to the destruction of its earth's surface real estate construction work, studies thus earthquake-resistant real estate building.
The utility model is this can earthquake-resistant real estate building; to be based upon to seismic wave model testing and on the basis of earthquake elastic wave, inertial wave, the research of flutter ripple; and the antidetonation embodiment proposing; be that double-layered ground is to move braking; dissipation seismic wave combined stress; slowed down the impact force of seismic wave to building, real estate building has obtained protection in earthquake thus.
