pob zeb load-bearing qauv yog siv rau hauv kev tsim kho los muab cov tsev nrog ntsug rigidity. Lawv hloov tag nrho lub nra ntawm lub tsev mus rau hauv av thiab yog ib qho tseem ceeb heev hauv kev tsim kho.
Muaj ntau ntau yam ntawm cov qauv tsim. Txhua yam muaj ib tug tej yam load peev xwm, yooj coefficient, zoo thiab tsis zoo. Feem ntau, txhua kab yog siv nyob rau hauv kev tsim kho ntawm ntau-storey vaj tse, ntxiv dag zog rau balconies thiab terraces. Cov qauv tsim tuaj yeem ua tau raws li qhov qub thiab muab lub tsev zoo nkauj, nthuav ntau dua. Tsis tas li ntawd, pob zeb pob zeb tuaj yeem yog puag ncig, square lossis duab plaub.
Ntau yam ntawm cov vaj tse pob zeb
Muaj monolithic thiab prefabricated kem. Prefabricated qauv nyiam nrog lawv cov nqi thiab kev sib dhos ceev, vim qhov tseeb tias cov blocks yog tsim nyob rau hauv factories, xa mus rau qhov chaw tsim kho thiab tsuas yog tom qab ntawd sib sau ua ke. Cov qauv monolithic yog nchuav rau ntawm qhov chaw tsim kho, uas txhais tau hais tias koj yuav tsum siv sijhawm ntau tos kom sib tov kom qhuav. Tsis tas li ntawd, rau cov qauv monolithic, nws yog ib qho tsim nyog los npaj cov txheej txheem zoo thiab ua haujlwm ua ntej.
Qhov zoo ntawm cov pob zeb pob zeb
pob zeb pob zeb yog qhov ruaj khov heev. Cov qauv zoo li no ruaj khov, hluav taws kub resistant thiab zoo kawg nkaus tiv nrog atmospheric influences. Vim cov khoom siv dav dav, tus nqi qis heev.
Disadvantages of concrete columns
Txawm hais tias muaj ntau qhov zoo, cov pob zeb ua vaj tse tseem muaj qhov tsis zoo. Yog tias qhov kev suav ntawm qhov kev cia siab tau ua nrog qhov yuam kev, ces tawg ntawm cov qauv thiab txawm tias nws puas tuaj yeem ua rau yav tom ntej..
Xaiv hom kab kem
Muaj ntau yam tseem ceeb uas yuav tsum tau xav txog thaum xaiv hom pob zeb. Cov xwm txheej no suav nrog:
- huab cua hom;
- av nta ntawm qhov chaw tsim kho;
- npaj theem ntawm kev thauj khoom ntawm tus qauv;
- storey thiab tsev loj.
Xaiv tus qauv tsim, nws raug nquahu kom hu rau ntau tus kws tshaj lij rau kev tawm tswv yim. Nws yog qhov zoo dua los xam cov pob zeb ua ke nrog cov kws tshaj lij hauv cov tuam txhab tsim kho, vim tias los ntawm kev suav ntawm koj tus kheej, koj tuaj yeem ua yuam kev loj. Yog tias tsis muaj peev xwm nrhiav kev pab los ntawm lub tuam txhab tsim kho, ces kev suav tuaj yeem ua hauv online. Nco ntsoov tias qhov no yog theem tseem ceeb heev thiab lub luag haujlwm ntawm kev tsim kho. Lub zog thiab kev ntseeg siab ntawm cov pob zeb ua kom muaj zog thiab lub tsev tag nrho yog nyob ntawm qhov kev xaiv raug thiab suav.
Thaum xam cov pob zebkab lus xav txog:
- Kab hom.
- Ntau thiab chav kawm ntawm rebar.
- kwv yees load (nws yog ib qho tsim nyog sau cia tias qhov ntsuas no tseem siv rau hauv tus account qhov hnyav ntawm kem nws tus kheej).
- Zoo thiab chav kawm ntawm pob zeb.
- kab loj.
pob zeb kem tsim thiab nchuav txheej txheem
Yuav kom sib sau ua ke cov txheej txheem precast, koj yuav xav tau cov khoom siv thiab kev ua haujlwm, nws yuav tsis siv sijhawm ntau, yog li peb yuav tsis xav txog cov txheej txheem zoo li no.
Nws yog qhov nyuaj dua rau nchuav cov pob zeb monolithic. Kev teeb tsa yuav tsum tau ua ntawm qhov chaw tsim kho.
Tom qab xaiv hom monolithic ntawm kev tsim kho thiab suav cov khoom siv uas xav tau, nws yog qhov tsim nyog los pib npaj cov txheej txheem ntawm nchuav txhua. Nws yog ib qho tsim nyog los xaiv cov hlau rau fittings uas muaj zog thiab weldability. Nws kuj yuav tsum muaj adhesion zoo rau pob zeb.
Ua ntej koj pib sib sau ua ke, koj yuav tsum tshem thaj chaw ib puag ncig. Nws yog ntshaw kom ua lub formwork nyob rau hauv daim ntawv ntawm ib lub tog raj kheej, lub cheeb ntawm uas coincides nrog lub cheeb ntawm lub yav tom ntej kem. Nyob ib ncig ntawm lub tog raj kheej yog npog nrog lub ntiaj teb, thiab ib qho kev sib xyaw ua ke yog nchuav rau hauv nws. Lub thav duab ntawm kem yuav tsum tau mounted los ntawm muaj zog, tuab reinforcement. Cov fittings yuav tsum tau ntev li ntev tau thiab fastened nrog hlau mus rau rods protruding los ntawm pre-npaj foundation. Thaum lub thav duab yog tag nrho sib sau ua ke, lub zog yuav tsum tau qhwv nrog ib daim ntawv ntawm galvanized steel. Galvanized steel yuav tsum tau kho raws li qhov zoo tshaj plaws, xws li thaum lub sij hawm sau nws yog assumedlub nra hnyav rau lawv. Tom qab npaj cov qauv, koj tuaj yeem mus rau pouring lub pob zeb sib tov, qhov kev xaiv uas yuav tsum tau ua nrog tag nrho lub luag haujlwm. Filling yuav tsum tau ua nyob rau hauv cov khaubncaws sab nraud povtseg. Cov kev daws teeb meem yuav tsum tau ua ntu zus kom cov pa npuas tsis tshwm nyob rau hauv cov qauv. Yog tias tsim nyog, lub formwork thiab cov thav duab reinforcement yuav tsum raug kho.
Tom qab nchuav cov qauv pob zeb, nws yog qhov tsim nyog los rhuav tshem cov formwork. Dismantling yuav tsum pib tsuas yog tom qab cov pob zeb sib xyaw ua kom tiav, thaum cov qauv tau txais cov yam ntxwv tsim nyog. Dismantling tsis yog ib qho yooj yim txheej txheem, yog li nws yog ib qho tsim nyog los tso siab rau qhov no rau cov kws tshaj lij uas paub txog dab tsi ua raws li cov qauv tsim yuav tsum tau muab tshem tawm. Nws yog ib qho tseem ceeb thaum lub sij hawm dismantling txheej txheem kom tsis txhob puas lub kem thiab ua kom nws zoo, yog li ntawd, ua ntej pib, koj yuav tsum tau xyuas kom meej tias cov pob zeb muaj zog.
Cov kab ke ua vaj tse yog qhia hauv qab no. Txhim kho lawv hauv av yog qhia meej.
Txoj kev teeb tsa ntawm cov pob zeb muaj zog
Kev txhawb nqa pob zeb tau pom zoo kom muab tso rau ntawm cov npoo ntawm cov qauv thiab cov tsev. Cov qauv yuav tsum tau kho rau lub hauv paus thiab qab nthab nrog anchors.
Kev txhim kho cov kab ke yog cov txheej txheem siv sijhawm ntau thiab nws nyuaj heev los daws nws ntawm koj tus kheej, yog li peb xav kom koj nrhiav kev pab los ntawm cov kws tsim khoom tshwj xeeb.
Yog xav tau, qhov tsim no tuaj yeem hloov nrog lub phab ntsa me me ua los ntawm cib. Koj tuaj yeem ua cov phab ntsa ntawm koj tus kheej, thiabnws yuav raug nqi tsawg. Nws qhov tsis zoo yog tias nws yuav tsis tiv taus ntau dhau.
Tsis txhob hnov qab txog cov kev txhawb nqa hauv nruab nrab ntawm lub tsev, vim tias lawv yog cov khoom siv tseem ceeb heev. Lub installation ntawm xws li kev txhawb nqa xyaum tsis txawv ntawm lub installation ntawm kev txhawb nqa nyob rau hauv cov npoo ntawm cov qauv. Qhov txawv tsuas yog qhov rebar yuav tsum tau siv nrog ib seem hlau.
Kev hloov cov pob zeb ua ke
Raws li lub hom phiaj ntawm kev siv cov kab, lawv tuaj yeem hloov nrog cov ntaub ntawv hauv qab no:
- Square steel kav (yuav siv tau nyob rau hauv kev tsim kho ntawm ib-zaj dab neeg los yog ob-storey tsev, ntawm cov ces kaum ntawm lub tsev).
- Cib kab (nws yog qhov tsis xav siv yog tias npaj thauj khoom loj, vim tias cov khoom siv tsis tshua muaj zog thiab tsis tuaj yeem tiv taus qhov hnyav ntawm cov qauv).
- Cov qauv ntoo uas tuaj yeem ua los ntawm cov ntoo lossis cov cav ntoo (nws tuaj yeem siv rau hauv cov qauv zoo ib yam li veranda, gazebo).
Rau yuav luag tag nrho cov qauv no, nrog rau kev txhim kho cov pob zeb ua vaj tse, nws yuav tsum tau siv lub crane siv thiab koom nrog ntau tus kws tshaj lij.
Nws yog ib qho tsim nyog yuav tsum nco ntsoov ib zaug ntxiv tias cov txheej txheem ntawm cov kab sib xyaw nrog cov pob zeb sib xyaw yog siv sijhawm ntev heev, uas txhais tau hais tias nws nyuaj rau koj tus kheej. Nws yuav tsum muaj lub luag haujlwm zoo, kev txawj ntse thiab lub peev xwm los ua haujlwm nrog cov ntaub ntawv no. Nyob rau hauv tus txheej txheem ntawm concreting, nws yuav tsum tau ua raws li ntau txoj cai uas tau teev saum toj no.
