Background technology

In various natural disasters, earthquake is the most sudden and destructive.Strong earthquake can make structure collapses, makes Become great economic loss, even harm human life's safety.Neighbour circum-Pacific seismic belt, China east, south connects Eurasian earthquake zone, Being one of earthquake disaster is most in the world country, seismic profile is the most extensive.The short forecasting success rate of earthquake is the lowest, the U.S. Scientist is it is proposed that " earthquake is uncertain ", for reducing the loss that earthquake brings, only starts with from building (structure) building structure, carries The shock resistance of high buildings or structures.The aseismatic design concept that various countries are commonly used now is by suitable design, makes to build (structure) building structure forms ductility construction system.On the basis of tradition buildings or structures are fixed on, its design philosophy is to resist earthquake to make With based on " resisting ", the intensity of the structural elements of buildings or structures itself and plastic deformation ability is i.e. relied on to resist earthquake and make With, absorb seismic energy.Its means are essentially increasing section, increase arrangement of reinforcement, increase structure integral rigidity, its mesh of providing fortification against earthquakes It is designated as " no damage in small earthquake ", " middle shake can be repaiied ", " no collapsing with strong earthquake ".

Along with going deep into and socioeconomic development of China's reform and opening-up, (structure) building structure system of building becomes increasingly complex, people To build (structure) build use function requirement more and more higher.It addition, it is increasingly sophisticated to build the equipment within (structure) building structure, finishing etc. And costliness, the anti-seismic performance of structure is proposed higher requirement, the method for structure " the most anti-" can not meet and has been actually needed.For solving Certainly this problem, scholars has carried out numerous studies, and on this basis, seismic isolation structure system gradually grows up.Shock insulation skill Art refers to build between basis, bottom or substructure building (structure), arranges by the parts such as shock isolating pedestal and damping unit, composition tool There is the Seismic Isolation of Isolation Layer of integral reset function, to extend the natural vibration period of total system, increase damping, reduce input superstructure Geological process, thus reach to expect shockproof requirement.Seismic isolation technology can reduce earthquake response 1/12 to 1/4, reaches that " middle shake is not Bad ", the target of " big shake can repair ".Seismic isolation technology can protect superstructure internal unit and finishing in earthquake greatly simultaneously Middle damage.In seismic isolation technology, Base Isolation Technology is the most ripe, this technology set up defences strategy based on " every ", " with soft gram Just ", utilize special isolated component, to be concentrated in the bigger relative displacement of Seismic Isolation of Isolation Layer, intercept seismic energy and tie to top Structure transmits, and makes buildings or structures have higher reliability and safety.

Year, house town and country construction portion issued " the some suggestions subtracting seismic isolation technology about building engineering popularization and application ": Encourage emphasis set up defences class, special set up defences class building and be positioned at building of seismic fortification intensity 8 degree (containing 8 degree) above Areas of High Earthquake Intensity district Build employing and subtract seismic isolation technology.To seismic seeurity or use function have the standard of high requirements set up defences class building advocate employing subtract every Shake technology.It is positioned at seismic fortification intensity 8 degree (containing 8 degree) above Areas of High Earthquake Intensity district, key area for earthquake surveillance and protection or earthquake disaster Newly-built 3 layers (containing 3 layers) of rear phase of regeneration to go to school, kindergarten, the densely populated place public building such as hospital, should preferentially use and subtract Seismic isolation technology is designed.

Using most in the isolation structure that China is current is laminated rubber damping bearing.Laminated rubber damping bearing is logical Over cure is bonded together rubber with steel plate, and steel plate constraint rubber provides bigger vertical rigidity.And when coming earthquake, The rubber of steel plate interlayer can with occurred level to deformation, the natural vibration period of extending structure, thus reach to reduce seismic energy upwards The purpose of portion's structure input.But now widely used laminated rubber damping bearing, has cost high, makes with construction technology relatively For complicated feature, it is not appropriate for applying in the median low structure in the vast villages and small towns of China, and villages and small towns folk building is China The main carriers of earthquake disaster.In Wenchuan County in Sichuan violent earthquake, villages and small towns area in, low-rise building destroy be particularly acute, therefore, Antidetonation shock insulation for rural areas in our country present situation is studied extremely urgent.Cai Kangfeng etc. analyze the earthquake reason of rustic home, Appeal that exploitation is suitable to low cost shock insulation material and the seismic isolation technology of rural area, improve rural area with this and build the antidetonation energy that (structure) is built Power.

The simple seismic isolation technology of current low cost includes junked tire seismic isolation technology, rubber powder seismic isolation technology, sand and rubber Grain seismic isolation technology, SBS modified pitch seismic isolation technology, Colophonium-sand, rubber beams (tire bundle) seismic isolation technology, reinforcing bar Colophonium shock insulation skill Art, fiber rubber seismic isolation technology, fiber reinforcement engineering plastics plate laminated rubber vibration isolating technology etc..Generally speaking, its material is main It is sand, junked tire, reinforcing bar, Colophonium and fiber etc..

In on August 16, in, world-renowned american car trade journal Wardsauto announces, and by the same day, Chinese automobile is gathered around The amount of having is 78,000,000.Along with the progress faster of global industry, solid waste increases year by year, has the title of " black pollution " Junked tire be exactly one of them.According to statistics, the annual Scrap tire about 2,000,000,000 in the whole world, it reclaims and processes the also Cheng Liao world A difficult problem for property.In recent years, the junked tire day by day increased cycling and reutilization in civil engineering, have become as social economy and A hot issue in Environmental Development.Nowadays country encourages green building, and energy-conserving and environment-protective, if can close junked tire Reason uses, and not only alleviates environmental pollution, also provides welfare for building trade.Junked tire is applied to grinding of building construction industry Study carefully the most considerably less.It is thus desirable to propose one to utilize junked tire, both it is provided that enough bearing capacities, there is the energy that well consumes energy simultaneously Power, limit function, the novel seismic isolation structure system of reset function.

Present Research both at home and abroad

1. tyre pads vibration-isolating system

The key component of tire has natural rubber, synthetic rubber, all-steel cord or nylon cord, steel bead wire, white carbon black And other auxiliary agents, when superposition of being cut into slices by tire uses, the steel wire in tire and the steel plate effect in laminated rubber damping bearing Similar, the vertical rigidity of tire isolation cushion can be improved, by reasonably design, stacked wheel tyre cushion is placed in building, can be right Structure plays certain function of shock insulation.Chen Wen, Xiong Feng propose a kind of tire isolation cushion (STP) utilizing junked tire to make, It is the crown formation tire isolation cushion of superposition multilamellar junked tire, and lamination junked tire isolation cushion figure is as it is shown in figure 1, lamination gives up Used tire pad vibration-isolating system schematic diagram is as in figure 2 it is shown, be laid under foundation ring girder formation flexibility at a certain distance in Fig. 2 Seismic Isolation of Isolation Layer.

Deng when the tyre pads number of plies is different with the mode that stacks, the waste tire of automobile pad of different brands is carried out axial compression examination Test and test with static shear, test machinery and the dynamic trait of tire, it is proposed that the rigidity of the rectangular pad of two major axes orientations Computing formula.Junked tire the first stack shown in mode figure such as Fig. 3 (a), junked tire the second stacks mode figure such as Fig. 3 Shown in (b), Fig. 3 (a) and 3(b) in every layer of mat be all two panels or three tyre pads interlacings form, with Chen Wen, Xiong Fengsuo The difference doing tire isolation cushion is that both stack mode difference.

But the limit function of this vibration-isolating system, reset capability are limited, under rarely occurred earthquake, if the structure changing of the relative positions is relatively big, top master Body structure has dislocation landing and the probability toppled.

Rubber for tire bundle vibration-isolating system

The University Of Chongqing Li Ying people etc. propose Colophonium-sand, rubber beams vibration-isolating system, at Shangdi collar tie beam and the lower geosphere of building The bound rubber beams that between beam, built-in one junked tire is made, the middle part along rubber beams height is stayed and is set one Colophonium-sand sliding Layer, fills up the space between rubber and concrete with Colophonium ointment, and wherein bound rubber beams can play position-limiting action.Binding rubber Micelle vibration-isolating system schematic diagram is as shown in Figure 4.

This system is when earthquake, and rubber beams is once cut off destruction will lose its function, exist necessarily in aftershock temporarily Danger, its safety and shake after function continuity be worth discussion.

Rubber grain vibration-isolating system

Still keep equal utilization waste rubber granule and sand is mixed to form the thick mixture bed course of at least 200mm according to a certain ratio As shock insulation material, and carry out shaketalle test, it was demonstrated that the existence of rubber grain, rubber grain-sand can have been efficiently reduced and mix The dynamic shear modulus of compound, and the content obtaining rubber grain to control the stability of structure when about 35% best.Rubber grain- Sand cushion isolating schematic diagram is as shown in Figure 5.

Xiong Wei etc. use rubber-sand grains mixture to carry out shock insulation as foundation ditch backfilling material.When different acceleration Shaketalle test result under Cheng Qiangdu shows, maximum output acceleration can reduce 30% to 50%, it is possible to ensure that structure is in macroseism Safety under Zuo Yong.And isolating affection proposed with increasing of rubber grain content and thickening and becoming apparent from of cushion thickness, Suggestion rubber-sand bedding course thickness in Practical Project is no less than 200mm.

Place under the foundation as Seismic Isolation of Isolation Layer Deng using the mixture of rubber grain with soil, by changing thickness of soil, structure sheaf Number, structure width and buried depth etc., carried out numerical simulation analysis.Research shows: rubber grain-soil hybrid isolation layer can subtract The geological process of light superstructure, horizontal and vertical seismic loads decreases 60% to 70% and 80% to 90% respectively, ordinary circumstance Under, the acceleration of structure and story drift can reduce 40% to 60%.

Shi Jianbo etc. are obtained by shaketalle test, and when sand mixes with rubber grain, rubber content of colloid grain brings up to from 0% 40%, the aseismic ratio of structure rises very fast；When rubber content of colloid grain brings up to 60% from 40%, the aseismic ratio of structure rises and tends to flat Slow, explanation is not that the biggest damping effect of content of rubber grain is the best, and the isolating affection of the big shock insulation bed course in sand grains footpath is preferable. Test the most further and draw when rubber grain volume content is less than 50%, shock insulation when rubber grain volume content proportioning is 45% Best results.

Earthquake isolating equipment under the sand-rubber combined wall of a kind of band steel strand wires of proposition such as Wu Yanhui, on basis and top during construction Adding steel strand wires between structure, this device is provided with certain limit levels sliding displacement while inheriting sand cushion isolating performance Function, improve under geological process function continuity after building safety and shake.

Liu Fangcheng etc. propose geotechnical grid reinforcement rubber granule Seismic Isolation of Isolation Layer.Geotechnical grid is that cellular three-dimensional restriction is System, has the structure of powerful lateral limitation and rigidity, rubber soil is inserted the geotechnical grid of expansion, can improve prose style free from parallelism rubber soil Vertical modulus of compressibility, formed and there is the composite construction layer of good integrity.Drawn by numerical simulation analysis: consider simultaneously every Shake effect and economy, take Seismic Isolation of Isolation Layer thickness be 200mm, rubber sand match ratio be 30% preferable.

But needing to excavate the certain thickness earthwork during application of this system, quantities is relatively big, and rubber grain size is to knot Whether structure isolating affection has an impact needs to be studied further.Steel strand wires and the use of geotechnical grid, serve certain spacing work With, but construction costs also has corresponding raising, and structural system reset function is limited simultaneously.

Rubber powder vibration-isolating system

Dong Chengchun points out to add a certain amount of binding agent or accelerator etc. in the rubber powder of different-grain diameter, stirs After cure can be made into cylinder or cube isolated component.But the method is comparatively laborious, the more cost that adds of manufacturing procedure, and Its performance is unknown, also needs to test further.

Wang Rui, woods honor etc. of shaking proposes rubber powder as the material of Seismic Isolation of Isolation Layer, by different meshes and ulking thickness Rubber powder carries out quasistatic compression test, and result shows: the timing of rubber powder bed course mesh number one, under identical experiment power, and rubber powder The deformability of bed course strengthens with the increase of ulking thickness；When rubber powder ulking thickness increases to a certain degree, 80 mesh rubbers The deformability of rubber powder bed course is stronger；And energy absorption ability is the most different with the different affecting factors of experiment power, rubber powder shock insulation Schematic diagram is as shown in Figure 6.

Xie Yongliang etc., by rubber powder adds unloading and shaketalle test, simulate the shock insulation under blast impulse vibration environment Problem, uses linear isolation system and the linear Stiffness model solution case history of rubber powder bed course, and comparing calculation knot Fruit and result of the test draw, use result of calculation and the result of the test more phase of rubber powder bed course linear Stiffness isolation system Closely.

Superfine rubber powder is carried out further experimental study, by static(al) Experiment on Hysteretic Behavior and vibration table frequency sweep Test obtains rubber powder mesh number when being 80 mesh, and the ulking thickness of rubber powder is the biggest, and load capacity is the biggest, and isolating affection is the best.

This vibration-isolating system has certain function of shock insulation, but not only needs to excavate the certain thickness earthwork during actual application, And owing to rubber powder consumption is more, waste time and energy in manufacturing process, virtually improve engineering cost, simultaneously structural system Reset function is limited.

Experimental performance is as follows:

In this utility model, the vertical rigidity of lamination junked tire isolation cushion is relevant with its planar dimension and the lamination number of plies, flat Size the biggest vertical rigidity in face is the biggest, when lamination junked tire isolation cushion planar dimension is 180mmX180mm lamination 8 layers There is provided 82.5 KN/mm(design compressive stress 3MPa), 115.0 KN/mm(design compressive stress 4MPa), 137.7 KN/mm(design pressure Stress 5MPa), 144.6 KN/mm(design compressive stress 6MPa) vertical rigidity.

Lamination junked tire isolation cushion planar dimension is often to organize two during 180mmX180mm lamination 8 layers to carry out level to power Performance test obtains: horizontal rigidity is that 4.38 KN/mm(design compressive stress 3MPa) 5.23 KN/mm(design compressive stress 4MPa), 5.22 KN/mm(design compressive stress 5MPa), 5.84 KN/mm(design compressive stress 6MPa).

According to embodiment 1 and embodiment 2, when lamination junked tire isolation cushion planar dimension is 180mmX180mm lamination 8 layers Vertical rigidity is level designs compressive stress 3MPa to the 18.8(of rigidity) times, 22.0(design compressive stress 4MPa) times, 26.4(designs Compressive stress 5MPa) times, 24.8(design compressive stress 6MPa) times, the long-range level of vertical rigidity to rigidity and test hysteresis loop more Full, show that this utility model can preferably dissipate seismic energy to play function of shock insulation.This utility model can be by adjusting Convex on the degree of depth of teeth groove 3 on lamination junked tire isolation cushion planar dimension, the lamination number of plies, lower ground collar tie beam 1, Shangdi collar tie beam 2 The height of tooth 5, the height of square groove 10, the height of force transmitting board 14 and length etc. are because usually regulating vertical rigidity and level to rigidity And the two ratio, and then play good isolation property.Isolation property test in, when to modular level to promote relative displacement When reaching 60mm, the maximum residual displacement of component is only 8.3mm, has embodied the excellent reset function of this structural system.

Above technical characteristic constitutes embodiment of the present utility model, and it has stronger adaptability and implementation result, can Increase and decrease non-essential technical characteristic according to actual needs, meet the demand of different situations.
