Abstract

The invention discloses an independent stiff cable which is used as an internal structure of a building by the flexibility of the steel cable. The independent stiff cable solves the problem of instant collapse occurred at connections of new posts or old posts and new beams and large plate hanging positions during a strong earthquake, which is caused by only using reinforcing steel bars and steel plates in a traditional building. The scheme comprises the steps of: additionally adding twisting or shuttling steel cables in a steel structure of generally designed reinforcing steel bars and steel plates and the like and connecting all parts of the whole building; therefore, the anti-earthquake flexibility of the whole building is effectively enhanced. Or, a steel cable is used for connecting anew beam group and a new post group so that the foundation of old bridge pile becomes large, deep and stable enough. Or, the steel cable is used for connecting the new beam group and the new pile group so that the foundation of the old pile becomes vast enough. The leverage effect is added, thereby the bending degree of pipe pole bodies is controlled. The shocking energy is quickly dispersed, absorbed and conducted, thereby seismic intensity is greatly reduced to a zero-destructive power degree.

Description

Independent stiff cable

Technical field:

The present invention relates to be a kind of with " cable wire " as the shockproof disconnected device of interior of building and utilization thereof.

As: first, be used in building and dam etc. usually and build thing, its structure RC is exactly steel concrete, SC is exactly steel reinforced concrete, SRC is exactly that the reinforcing bar reinforcing bar mixes soil.According to the present technology problem of giving birth to be: go through disorderly the pullling and return when squeezing rapidly of the high torsion of 3D angle high-frequency of violent earthquake, often make between the steel interior molecules, through this violent torsional motion, and make part build thing living moment result of caving in.Especially unsettled place, column beam joint place, or the long vast area floor of distance etc. caves in the soonest.Study carefully its error principle: a reinforcing bar or reinforcing bar, its characteristic are both after bending, must be softening through very high temperature, just can do no nocuity answer; If it is under normal temperature, strong when doing the action that cyclic bending replys again; Then must give birth to high temperature, the regeneration slight crack is eventually to dissociating.B steel plate or reinforcing bar building materials are all transported length and width and are limited, so cut into bits here and there before dispatching from the factory earlier; Do combination in the building site again; Its mode is nothing more than first overlapping reinforcing bar steel plate, again with the thin wire binding, or welding, or the locking of mat screw etc.Then stay naked eyes unavoidably and be difficult to the flaw discovered; When meeting with macroseism, countless big or small slight cracks appear earlier in concrete, and allow acid rain have the pipeline of infiltration causticize steel to make it from the coarse to fine; Therefore chemical change again, and grow the powerful bulbs of pressure, and then push concrete structure, to strengthening and widening the rift, with the passing of time after the vicious circle, if meet with macroseism again, namely moment collapses; Causing does not have the escape chance and injures and deaths.The present situation problem of second, just early stage bridge it " pier footing part ": because finance, technology, equipment were owed foot at that time, or do not adopt sand as yet because of the riverbed and reach firmly, so its pile generally presents " short, shallow, little " phenomenon, nowadays the riverbed transfinites because adopting sand, causes that to be faced with bridge pier exposed serious, must empty excessively if meet with torrent again, and shake old pile, must not prop up to fall eventually and form bridge cut-off, related numerously fall in the tumbling torrent with bridge people car is gone for ever; Bridge cut-off events such as Ru Houfeng, Li Gang, Pingdong go out not poor thoroughly, thereby seriously perplex the vast passerby of using, and shake local leadership, hinder local economic development ... Deng.And the prior art field: be to be to peel off behind the pile epidermis welded reinforcement etc. earlier, however the welding high temperature explosive split, and destroy pile intensity, or pad is not enough to borrow power, cause and be difficult to load and come off So this item " technology of the old bridge pier of reinforcement " is if " can't reach safety standard "; Then indulge very new bridge, in " bridge pier is exposed and then give birth to the continuous expansion of displacement, and is listed as the danger emigrant "; Only remain " remove and rebuild " way undoubtedly.As new increase bridge etc., a seated connection one and is removed reconstruction.The third, with regard to the problem of cable car pile part: " be the pursuit on the visual field, must build on the thin and weak mountain Period, so pile earlier in the sky system is seated on the extremely harsh geological conditions, as the Great Wall; Because of reciprocations such as running or wind-force or earthquakes, cause pile " excessively to rock " phenomenons such as sloping soil again; And grow periphery basic native stone loose landslide gradually, and with the passing of time cause pile to lose support should be arranged, have in the end as the Taibei city cat cable T16 post, be forced to move bar with temporary transient solution landslide problem.

Background technology:

Cable wire contains common cable wire, stainless steel cable or zinc-plated electric pole cable wire etc., and in transportation, wall scroll monovolume length reaches more than the kilometer; Cable wire characteristic tool: " integrally formed non junction, the bending impact that gets arbitrarily volume easy construction in the wrong, the high torsion of ability high-frequency high reps high angle " etc.It must be at " wall scroll ", and " single seam ", " winding side or circle thing around ", the steel mesh reinforcement bundle of " or pass, through " its beam or post or floor etc., and link up or enclose around whole floor one; Then finish the task of " not allowing that individually the firm antidetonations of separation are built the thing structure alone ".This engineering effort: " be reinforcing bar and steel plate, forever institute can not reach ".Whether study carefully the experience macroseism and collapse suddenly, the core key is: " material at beam and column joint place, the bending torsional buckling of the high torsion of high angle high reps high-frequency in the time of whether resisting earthquake ".Just tough as it " ligament " on our the bone joint on its speciality.Now do following material test: glass bar, piece, bending is just cracked slightly at normal temperatures; But same composition weight, but through dissolve be pumped into thread, become the topknot shape again after, the vertical bending torsional buckling that meets with as the high torsion of high angle high reps high-frequency as the macroseism ", still can save from damage as before.Hence one can see that, same composition, and it is to the identical high torsion of high angle high-frequency, and the number of times when being fractureed, the area of deciding what is right and what is wrong with it just is inversely proportional to ".Still have, the inner anti-high voltage structures thing of high-speed tire is cable wire; It faces for a long time, the situation of high pressure, high-frequency, high angle distortion; Build the thing internal state when never being second to macroseism.In like manner can demonstrate,prove, the speciality of cable wire should meet the demand of beam and column joint place it " tough " fully.Only engineering circle is still unmanned so far finds and carries out, and is unfortunate very.So be the guarantee broad masses security of the lives and property, and strengthen for the purpose of the national power; Wise and able government seemingly should promote this kind building method with all strength.

Summary of the invention:

First, to big or small building and dam aspect: namely " all beams and the important joint of post; or the unsettled place of large tracts of land floor; in use cable wire before the grouting; shuttle back and forth in tendon, the side of net; or winding or pass one by one and preset in all multiple holes of steel plate or its gap make the whole image of building tightly be bundled by same cable wire; Make arbitrary position all be difficult to break away from separately or avalanche because of macroseism.Second, to old bridge pier post aspect: it is exposed to be that old bridge pier post is washed till the stone bone with hydrochloric acid earlier, secondly clean with water under high pressure, then twine earlier with cable wire and make a circle in this pile week, pass " in all multiple preset steel plate hole of the grade beam hole " more one by one or twine " tendon ", this new post and reach the n circle time, " old pile with new the new pile of beam " combined closely to break away from or to extend or mobile to desiring all not have to either direction, reach the complete stage by means of power and power transmission; Be same as first and new beam be combined with new pile as rule again, be in the milk at last and finish.The third, to the aspect of old cable car pile: it is identical with second that it makes rule.

Technical solution of the present invention is: independent stiff cable is divided into " first, structure and second, method " two blocks.Be the present invention with " cable wire " as " structure " aspect within the beam of [four kinds of buildings] and post and the plate etc.; With and implement " method " (details step) aspect.So comprise: when use 1, when big or small building, 2 reservoirs, dam etc.; First 1., " structure " feature: the beam or post or the floor that lie in common design, steel mesh reinforcement, bundle or various steel plate on, " additionally increase the cable wire of one or more; make eternal be attached to around the tendon, the gap or pass the steel plate hole or a side or as known various methods etc. of tiing knots at present, and be hidden in the concrete ".Effect: tie up to when meeting with macroseism, its can mat its not only long but also tough characteristic, and effectively solved: " simple reinforcing bar or various steel plate it " joint gathers, or itself is too firm, in case when meeting with macroseism, " the easy disengaging in joint, or easily fractureed ", cause and build thing moment and cave in, to everybody's casualties " problem; This is before to have needed to be resolved hurrily and the difficult problem that can't solve.Second 1., " method " feature: lie in the connection of important beam, post, plate partly, must twine back and forth or through n bar or n circle with same cable wire; And " important post " should do the above winding of half-turn; Namely twine around the steel plates such as tendon or H type or place side, or pass in the default hole of steel plate or as known various methods of tiing knots at present." beam or plate portion " then cable wire system is staggered is interspersed among steel mesh reinforcement, the bundle etc. or down.Make integral body build thing eventually, as by same cable wire bundling tightly, grouting at last.Effect: [vertical " reinforcing bar or steel plate " had no progeny by shake entirely, and remaining cable wire still can " hold out alone this broken build thing in not weighing down, so the name independent stiff cable ".Help common people's safe escape in macroseism.Because having buried cable wire, and make its more anti-" behaviour for a long time " as inner layer of tire again; In like manner, it makes that to build thing shatter-proof cable wire, unexpected tear fracture].When 3, being the pier footing of the old short and small weakness of rescue; First 2., " structure " feature: be bridge floor outer on the both sides, downstream, planting not only deeply but also huge ground pile group and is being supported new grade beam group and body of a bridge weight and a stabilization by it.And each new grade beam respectively is linked to " cable wire " respectively, on the independent one or both sides of each once visited place stake of same row; Effect: " old abutment plinth is become firmly by weakness "; As when disliking support force still not enough, the new pile of part must be increased to nearly bridge floor each angle cable wire of mat each point again, the new grade beam that tiltedly plays, " connect the support band and draw, help and weigh and consider in order to uphold justice ".Second is 2., " method " feature: a excavates table soil earlier, make the stake of whole once visited places partly to reach predetermined ground of new grade beam part exposed; B ends with the stone exposed bone that concentrated hydrochloric acid is washed till the pile skin again, and cleans with water jets under high pressure; C makes new grade beam with H shaped steel plate or tendon etc., twine old pile one by one with cable wire, and pass default each steel plate hole on the new grade beam or tendon or hole or winding or and place side, make each " new grade beam and old pile ", mat n bar cable wire twines n circle etc., and makes permanent binding; D and " old post opposite side " practice is also identical; Each does binding with two ends it " pile group top newly " to e each " new grade beam two ends " respectively, its practice and second 1., identical; F partly new grade beam must be exposed to newly side outside the pile group concrete, comprises length and the hole of following required binding, and paints to wait and protect, with the usefulness of reservation bridge enlarging; The whole H shaped steel plate that presents single or multiple lift and be parallel to each other of g or steel mesh reinforcement etc., the new grade beam group that is formed is erected at respectively on the crown of pile group newly of both sides.If h is when disliking holding power still not enough, get with bridge each side new pile increase to a little less than bridge floor; Divide many oblique cable wires of length again, each a plurality of angle respectively, each links and is hung in each default hole that is fit to of new post and new grade beam, sees outside finishing below the back axle like as two groups or the above Cable stayed bridge; After the i grouting, and the backfill earthwork; Make and can't see arbitrary change below the bridge; Or only see the structure of tiltedly opening part.Usefulness: b makes the cement grip darker tighter, wide, tightly and not seeps water, and metal is not corroded, Gu can be durable in use.C makes whole junction, all ability macroseism and tear-proof.D makes between many bases, connects to a shatter-proof individuality.4, moving the disappearing excessively of the old pile of cable car wasted the aspect: first 3., " structure " feature: stake centered by old pile, other increases (about 20 meters) far away new stake slightly more than, and do permanent prehensile or put side with " new grade beam " and with " cable wire " separately, etc. mode and linking between this once visited place stake and new pile, 1. identical with first to mode of connection.Usefulness: behind the new grade beam of mat increase new pile far away slightly and length slightly, can exempt former post it " agglomerate shakes phenomenon altogether "; And can produce lever usefulness, foot stops shaft by overflexing; And pressure ram limit topsoil stone; And increase the area that energy is shaken in diffusion, and make its vibration limits ability of minimizing, reach the microseism of not having injury eventually; And effectively protect environment soil stone stable, and do not give birth to landslide, do not jeopardize below resident's safety.Second 3., " method " feature: be do between new grade beam and once visited place stake in conjunction with the time, the method for its combination, a, b, c, i 2. is identical with second.Usefulness: the old post of winding of mat cable wire etc., economical simple and exempt to hurt the original structure of old post; And exempt fatigue and cost and the time of moving bar; And anticorrosive, the eternal anti-macroseism of energy percolation-proof does not make the column beam joint place break away from because of macroseism ".

And the cable wire kind comprises: Stainless Steel rope, common cable wire, galvanized vanized steel cable, electric wire be with galvanized vanized steel cable etc., should be with regard to the needs of construction environment and change.
