Abstract
The invention discloses a shock insulating foundation, comprising a cushion layer, a foam groove and a foundation plate. The flexible cushion layer adopts cooked sticky rice and lime mixed cushion layer. A rubber prefabricated concrete plate is arranged above the flexible cushion layer, rubbers are arranged in the middle of the rubber prefabricated concrete plate. Limesand paste and sticky rice lime paste are used for building between the foundation prefabricated plates. The rigid cushion layer uses woods to stagger and overlap layer by layer. Rubber cast-in-place concrete plates are arranged at the upper part of the rigid cushion layer. The foam groove is arranged on periphery of the cushion layer. The invention has good anti-shocking performance and strong practicability.
Description
Technical field
The present invention relates to building foundation, particularly a kind of shock insulating foundation.
Background technology
By the natural vibration period that basic anti-seismic construction comes extending structure, make structure avoid the high energy frequency band of seismic wave, the swing on basis is converted to the lateral displacement of basis to ground during with earthquake, and seismic energy is absorbed by the distortion on basis self.Make the earthquake proof foundation reduce distortion and crooked by construction measure, reduce and wave degree (earthquake acceleration), thereby play the effect of antidetonation.The earthquake proof foundation is born vertical load on the one hand, prolongs the vibrations cycle with its deformation characteristic on the other hand.The earthquake proof foundation must have sizable displacement and deformability in the horizontal direction.Traditional basis does not have shock insulation function.
Summary of the invention
At the deficiencies in the prior art, the objective of the invention is to solve the bad problem of base isolation performance.
The present invention includes bed course, foam groove, foundation slab.Bed course adopts flexible cushion or rigidity bed course; Around the bed course foam groove is set, the foam groove width is 40～50cm, and thickness is identical with cushion thickness; Foundation slab adopts rubber precast concrete plank or rubber cast in place concrete plate.Have rubber, rubber thickness to account for precast plate thickness 1/3～1/4 in the middle of the described rubber precast concrete plank, the cast-in-situ concrete that described rubber cast in place concrete plate is every 20cm is provided with one deck rubber, and rubber thickness is 5～8cm.
The present invention is provided with the influence that foam groove reduces seismic wave by around the bed course, and as the first line of defence of shock insulation, by the second road defence line of flexible cushion as shock insulation is set, flexible cushion adopts glutinous rice and the lime mixture bed course that boiled.Flexible cushion thickness is 30～50cm.
There is the rubber precast concrete plank flexible cushion top, has rubber, rubber thickness to account for precast plate thickness 1/3～1/4 in the middle of the rubber precast concrete plank.Every rubber precast concrete plate thickness is 15～20cm, and 3～5 precast plates are built up foundation slab.Build by laying bricks or stones with sand-lime cream or glutinous rice emplaster between the precast plate of basis.
The present invention can also be by being provided with the second road defence line of rigidity bed course as shock insulation, and the rigidity bed course adopts wooden layering to be overlapping, and wooden every layer thickness is 10～15cm, superposes 3～4 layers, and gross thickness is 40～60cm.There is the rubber cast in place concrete plate rigidity bed course top, and rubber cast-in-situ concrete plate thickness is 60～80cm, whenever waters the concrete of smashing 15～20cm one deck rubber is set, and rubber thickness is 8～12cm.
The present invention is at the basic four jiaos accelerometers of burying the band alarm buzzer underground, and accelerometer is embedded in the position from basic end face 10cm.
The present invention has very high vertical bearer properties and very little compressive strain, can guarantee the safety of building; The second, have bigger horizontal shape ability, shear strain can reach 200% and do not destroy; The 3rd, have the elastic reset characteristic, building is set back automatically.

The specific embodiment
Describe in detail below in conjunction with accompanying drawing.
Embodiment 1
Present embodiment comprises foam groove 1, flexible cushion 2, rubber precast concrete plank 4.
Dig the empty ditch that width is 45cm earlier around the flexible cushion 2, empty ditch thickness is 40cm, and empty ditch scrapes out the filling foam, and foam groove 1 plays the effect that reduces the seismic wave influence.
Flexible cushion 2 adopts glutinous rice and the lime mixture bed course that boiled.Flexible cushion 2 thickness are 40cm.There is rubber precast concrete plank 4 flexible cushion 2 tops.In the middle of the rubber precast concrete plank 4 rubber, rubber thickness being arranged is 5cm.Every rubber precast concrete plank 4 thickness are 15cm, and 5 rubber precast concrete planks 4 are built up foundation slab.Build by laying bricks or stones with sand-lime cream 3 between the rubber precast concrete plank 4, during earthquake, rubber precast concrete plank 4 produces and rocks flexible changing of the relative positions densification between the rubber precast concrete plank 4, not only make rubber precast concrete plank 4 more closely knit stable, and consume a large amount of seismic energies.
Embodiment 2
Present embodiment comprises foam groove 1, rigidity bed course 5, rubber cast in place concrete plate 6.
Dig the empty ditch that width is 45cm earlier around the rigidity bed course 5, empty ditch thickness is 60cm, and empty ditch scrapes out the filling foam.
The four jiaos of accelerometers of burying the band alarm buzzer underground in basis, accelerometer is embedded in from the position of basic end face 10cm, and this position earthquake brief acceleration is convenient to more again bury underground with survivable.
