Nyob hauv cov ntawv siv, lo lus "reinforcement" feem ntau pom. Lo lus yog txawv teb chaws, thiab cov ntsiab lus semantic tuaj yeem ua rau muaj kev ntxhov siab ntawm cov neeg uas tsis tshua paub txog qhov tshwj xeeb ntawm nws daim ntawv thov.
Rebar hauv kev tsim kho
Lub tswv yim kev lag luam "kev txhawb zog" tuaj yeem muab faib ua ob pawg loj ntawm lub ntsiab lus - qauv thiab thev naus laus zis.
Thawj yog siv rau hauv kev tsim cov vaj tsev. Reinforced qhob sib txawv ntawm cov monolith yooj yim los ntawm kev siv cov khoom siv thauj khoom, meshes lossis tawb.
Fittings ntsia rau hauv cov kav dej xa tawm thiab tswj cov dej ntws hauv cov dej thiab cov kav dej phwj tuaj. Sib sau cov ntsiab lus no ua haujlwm lub hom phiaj. Armature yog dab tsi ua rau kev ua haujlwm ntawm tag nrho cov txheej txheem.
kev txhawb nqa kev tsim kho
Cov qauv pob zeb yog hom tseem ceeb ntawm cov khoom siv hauv tsev. Qhob yog qee zaum hu ua pob zeb dag. Nws muaj kev tiv thaiv zoo heev rau compression, tab sis tawg kuj yooj yim thaum ncab thiab flexed. Qhov teeb meem no yog tshem tawm los ntawm kev ntxiv dag zog rau cov pob zeb loj nrog cov ntaub ntawvmuaj peev xwm ntawm absorbing tensile loads tsis poob ntawm lub zog. Kev loj hlob ntawm kev lag luam khoom siv hauv tsev tau nthuav dav ntau yam khoom siv fittings. Ntxiv nrog rau cov tsoos hlau, nws suav nrog cov khoom ua los ntawm cov khoom siv polymers, uas yog cov khoom siv ntxiv. Kev tshwm sim ntawm cov ntaub ntawv tshiab ua rau nws muaj peev xwm ua tau zoo dua rau hauv tus account cov yam ntxwv ntawm kev ua haujlwm ntawm cov khoom.
Txoj Cai Rebar Standards
Kev siv cov khoom siv thiab cov khoom siv rau kev tsim vaj tsev thiab cov qauv yog tswj nruj heev. Kev ua haujlwm nyab xeeb yuav tsum ua raws li cov qauv tsim los ntawm cov kws tshaj lij thiab tau pom zoo nyob rau theem kev cai lij choj. Steel reinforcement yuav tsum ua raws li GOST 10884-94, uas tswj lub cev thiab technical tsis ntawm cov khoom. Composite ua tau raws li qhov yuav tsum tau ua ntawm GOST 31938-2012. Steel rebar nkag mus rau hauv kev ua lag luam, raws li txoj cai, ua tau raws li cov kev cai, vim nws muaj kev tsim cov hauv paus tsim thiab kev siv technology. Hmoov tsis zoo, cov khoom ua los ntawm cov ntaub ntawv polymeric tuaj yeem muaj qhov sib txawv ntawm cov neeg siv khoom, uas yuav tsum tau ua tib zoo saib xyuas cov khoom yuav khoom. Nyob rau tib lub sijhawm, kev nyiam yuav tsum tau muab rau cov lag luam uas muab tag nrho cov yam ntxwv rau lawv.
steel reinforcement
Hlau los ntawm qhov kev txhawb nqa yog tsim (GOST 10884-94) tuaj yeem ua cov pa roj carbon thiab qis-alloy. Txhawm rau txhim kho adhesion nrog lub cev ntawm cov pob zeb, cov rods tuaj yeem muaj qhov profile raws sijhawm, cov kev txwv uas tau teev tseg hauv lub xeev tus qauv. Hom nokev txhawb zog yog qhov feem ntau pom thiab kawm tau zoo. Steel rebar yog ib txwm siv cov khoom siv ntxiv. Qhob reinforced nrog steel tuav, thav duab thiab meshes yog hu ua reinforced pob zeb. Yuav luag txhua lub tsev tsim yog tsim los ntawm nws, los ntawm lub hauv paus mus rau hauv pem teb panels thiab load-bearing ntsiab ntawm lub tsev thav duab. Factories tsim ib tug loj ntau yam ntawm reinforced pob zeb lug rau ntau yam hom phiaj. Niaj hnub no, kev tsim kho monolithic tau dhau los ua neeg nyiam, uas feem ntau ntawm lub tsev tsim tau tsim nyob rau hauv txoj haujlwm tsim los ntawm kev nchuav cov pob zeb rau hauv cov formwork nrog cov nteg reinforcing tawb. Yog hais tias nyob rau hauv lub prefabrication ntawm lub ntsiab txoj kev ntawm fastening rods yog welding, ces nyob rau hauv lub ntau lawm ntawm qhov chaw, qhov cuab lub zog yog feem ntau knitted nrog hlau. Ntxiv nrog rau kev txhawb nqa ntawm ib ntus profile, cov pas nrig du kuj tseem siv tau. Lawv lub zog adhesion rau pob zeb lossis mortar yog qhov qis dua, tab sis qee qhov kev siv cov khoom siv du-dov yog qhov tsim nyog.
Composite rebar rau pob zeb
Kev tsim kho niaj hnub yog hloov mus rau kev nthuav qhia ntau dua architectural thiab cov nqi qis dua. Polymer reinforcement tso cai rau koj ua qhov no zoo tshaj plaws. Ib qho txiaj ntsig tseem ceeb ntawm polymers hauv kev sib piv nrog cov hlau yog qhov hnyav dua thiab tsis kam tiv thaiv corrosion. Cov no suav nrog bas alt, carbon fiber, fiberglass reinforcement.
Cov yam ntxwv muaj zog ntawm cov khoom siv polymer feem ntau yogtshaj lub peev xwm ntawm steel. Zoo li cov hlau, cov khoom sib xyaw ua ke tuaj yeem yog ib ntus thiab qhov profile tsis tu ncua. Txawm li cas los xij, nws txoj haujlwm nyob rau hauv load muaj nws tus yam ntxwv. Tsis zoo li cov hlau, fiberglass reinforcement tsis ntws, thiab thaum lub siab tshaj plaws load tau mus txog, lub caij yog tam sim ntawd puas.
Steel vs composite: xaiv dab tsi?
Qhov xwm txheej ntawm kev ua haujlwm ntawm cov pob zeb ua kom muaj zog qhia tau tias muaj peev xwm raug cov dej noo ntawm qhov cuab lub zog thaum lub sij hawm qhib cov kab nrib pleb hauv cov khoom ua haujlwm hauv kev khoov thiab nro. Lawm, qhov no ua rau muaj kev pheej hmoo ntawm lub zog poob thiab txo cov kev pabcuam lub neej ntawm cov qauv. Thaum concreting los yog bricklaying nyob rau hauv lub caij ntuj no, cov hlau yog raug mus rau nruj kev txiav txim ntawm Frost-resistant additives, uas kuj tsim tau ib tug txo nyob rau hauv kev ua tau zoo. Cov ntaub ntawv Polymeric ua kom tsis txhob muaj qhov cuam tshuam tsis zoo ntawm corrosion ntawm cov kabmob ntawm cov tsev thiab cov qauv. Synthetic reinforcement muab qhov no. Txawm li cas los xij, cov khoom sib xyaw muaj qhov phem tshaj qhov hluav taws kub ua haujlwm, poob lub zog sai dua thaum rhuab. Qhov hnyav dua ntawm kev sib xyaw ua ke yog ib qho cuab yeej txaus nyiam rau tus kheej thiab kev tsim kho qis, uas, raws li txoj cai, tsis tau muab nrog cov cuab yeej nqa. Kev txo nqi tsheb thauj mus los thiab qhov chaw mus ncig yuav yog qhov tseem ceeb.
pib fittings
Qhov ntau ntawm kev siv fittings ntawm cov kav dej yog qhov dav heev. Nws yog siv nyob txhua qhov chaw, los ntawm cov kev sib txuas me me hauv kev lag luam ntiag tug mus rau cov khoom lag luam loj.qhov chaw. Cov yeeb nkab fittings hauv kev faib khoom sib txuas yuav tsum ua kom tau raws li cov kev xav tau siab rau kev nyab xeeb thiab kev ua haujlwm tsis muaj teeb meem. Cov ntsiab lus network no, uas sib txuas cov kev xav tau tsis sib haum xeeb, tuaj yeem yog qhov nyuaj heev. Piv txwv li, kaw-off li qub yuav tsum tiv thaiv hydrodynamic shock, uas nce mus txog qhov tseem ceeb ntawm cov yeeb nkab loj diameters. Yog li ntawd, cov hlau uas tsis yog hlau, xws li tooj liab thiab tooj liab, feem ntau suav hais tias yog cov khoom tsim nyog tshaj plaws, uas tso cai rau kev tsim cov khoom milled thiab cam khwb cia ntawm ntau qhov sib txawv. Txawm li cas los xij, lawv muaj tus nqi siab thiab tsis muaj zog. Yog li ntawd, steel, cam khwb cia hlau thiab polymers yog siv los ua cov ntaub ntawv los ntawm cov fittings yog tsim. Cov chaw tsim khoom tau lees paub qhov ua tau zoo ntawm cov khoom lag luam, uas tso cai rau koj los txiav txim siab xaiv ib lossis lwm yam khoom siv.
Polymers hauv cov kav dej sib txuas
Kev sib kis ntawm cov kav dej yas tau muab lub zog rau qhov pom ntawm cov khoom siv los ntawm cov yas lossis nrog cov khoom siv yas loj. Lawv nyiam tshaj plaws hauv kev siv pej xeem thiab kev lag luam ntiag tug. Qhov zoo dua tsis tuaj yeem hais tias cov fittings zoo li no yog qhov hnyav dua thiab tsis muaj corrosion ntawm cov kav dej thiab cov khoom sib txuas. Cov kav dej ua los ntawm cov ntaub ntawv polymeric tuaj yeem yog qhov ntev tsis txwv, sib piv rau cov qauv hlau loj. Lawv yooj yim heev rau kev sib txuas rau ntau txoj hauv kev.
Vuam ntawm polymers yog siv sij hawm tsawg dua thiab hluav taws kub piv rauhlau vuam. Ntxiv nrog rau qhov tsis muaj corrosion, cov kav dej thiab cov khoom siv polymer tsis raug cuam tshuam los ntawm cov nag lossis daus hauv cov kav dej thiab cua sov, uas tuaj yeem ua rau overgrowth ntawm qhov chaw sab hauv thiab txo qis hauv txoj kab uas hla. Kaw-off li qub, kev faib tawm thiab lwm yam, raug ntsia rau hauv cov kav dej siv cov txheej txheem siv hauv kev teeb tsa cov yeeb nkab txuas.
