Profiled ntawv yog cov ntaub ntawv uas tsim nyog tshaj plaws raws li kev teeb tsa nrawm thiab zoo. Ua tsaug rau galvanizing thiab pleev xim, nws tuaj yeem kav 20-30 xyoo ua ntej lub ru tsev pib xeb.
Qhov loj me
Qhov pom kev zoo ntawm daim ntawv profiled rau lub ru tsev yog qhov ntev thiab dav ntawm daim ntawv, nws cov tuab. Tom qab ntawd tus neeg siv khoom tau them sai sai rau qhov kev ntxhib los mos (piv txwv li nthwv dej), uas tso cai rau nag lossis daus (nag, yaj dej los ntawm daus lossis cua daj cua dub) kom tsis txhob kis mus rau ob sab, tab sis kom ntws zoo.
Cov txheej txheem thiab kev ua haujlwm thaum lub sijhawm tsim khoom, kev thauj mus los, kev teeb tsa thiab kev saib xyuas ntawm lub ru tsev uas twb tau teeb tsa raug tswj hwm raws li GOST №24045-1994.
Ntev thiab dav
Raws li qhov ntsuas no - tag nrho thiab muaj txiaj ntsig ntev thiab dav ntawm pawg thawj coj saib corrugated. Kev siv qhov ntev - dav thiab ntev ntawm daim ntawv tom qab tsim: zoo li nthwv dej, ua tsaug uas cov ntawv hlau tau txais lub ntsiab lus ntawm "cov ntawv sau ", tsis txhob cuam tshuam qhov tseeb ("ncab") thaj tsam ntawm cov khoom siv hauv tsev, tab sis ua rau txo qis qhov ntev.
Daim ntawv tshaj lij tsis nyob rau hauv vain ua nthwv dej: yooj yim ntawm kev teeb tsa, tiv thaiv mus ntev mus los ntawm cov dej los ntawm nag lossis daus tso cai rau koj kom tusyees nteg cov khoom siv hauv tsev no ua txheej txheej saum toj kawg nkaus ntawm lub ncuav mog qab zib, tiv thaiv nws los ntawm kev txav chaw nyob hauv nag xob nag cua, khoov ntawm daim ntawv. los ntawm cua muaj zog, tshuab hauv qhov tawg uas yuav tsim nyob rau hauv cov chaw ntawm cov kab no.
Rolled ntev - qhov ntev ntawm cov ntawv hlau yooj yim, tseem tsis tau nthuav tawm rau phaj khoov txoj siv thauj khoom. Qhov no yog qhov taw qhia ntawm kev siv cov hlau, zinc thiab xim hlau. Tsis yog siv cov hlau thiab pleev xim, lossis ntim hauv cov chaw khaws khoom los ntawm ib pawg ntawm cov ntawv zoo ib yam lossis cov ntawv txheeb nyob ntawm seb qhov ntev thiab dav yog li cas - dov thiab muaj txiaj ntsig. Cov ntawv sau tau raug khaws tseg - hais txog thaj chaw nyob ntawm lub ru tsev - tsuas yog nrog kev teeb tsa tiag tiag.
Kev nteg nrog kev sib tshooj ntawm ib lossis ib thiab ib nrab nthwv dej tso cai rau koj kom txo qis thaj tsam ntawm ob peb feem pua ntxiv
Hauv qhov tseeb, qhov txuag tau tiag tiag ntawm daim ntawv profiled yog qhov tsis sib xws: qhov sib tshooj tshem tawm ib feem ntawm qhov ua tau zoo qub ntawm daim ntawv profiled.
Tag nrho qhov ntev thiab dav - qhov nrug ntawm cov npoo ntawm daim ntawv . Qhov ntev ntawm daim ntawv profiled yog los ntawm 3 txog 12 m, qhov dav - los ntawm 0.8 txog 1.8 m. Los ntawm kev xaj ua ntej, qhov ntev ntawm daim ntawv profiled tau ua nyob ntev los ntawm 2 txog 15 m - rau cov xwm txheej uas luv dua lossis ntev dua profiled ntawv yuav tau nqa mus rau lub ru tsev lathing nyuaj. Qhov muaj txiaj ntsig ntev thiab dav yog qhov ntev kawg uas tseem tshuav tom qab rho tawm qhov sib tshooj.
Qhov ntev ntawm daim ntawv raug xaiv raws li txoj hauv kev uas nws sib haum rau qhov ntev ntawm txoj kab nqes (rafters) thiab qhov deb uas lub ru tsev dai sab nraum ib puag ncig ntawm phab ntsa . Qhov tom kawg suav nrog qhov ntxiv 20-40 cm. Thaum siv cov ntawv luv luv, cov khoom siv tau muab tso nrog kev sib tshooj, uas txo qhov ua kom tsis muaj dej tsis zoo ntawm lub nkoj thiab rafters. Kev sib tshooj tsis tuaj yeem ntau dua ib nthwv dej.
Thickness thiab qhov siab
Cov ntawv hlau tau xaiv hauv tuab sib npaug li 0.6-1 hli. Hlau thinner tsis tuaj yeem siv tau - nws yuav raug rau hauv qhov cuam tshuam los ntawm lawg, daus lossis los ntawm cov tib neeg taug kev saum ru tsev . Cov ntawv hlau uas muaj cov hlau tau yooj yim puas txawm tias nyob rau theem teeb tsa - tsis txhob txuag ntawm qhov tuab. Ib ntus, tab sis qhov kev daws teeb meem phem tshaj plaws yog txhawm rau ib zaug 2-3 nplooj ntawv nrog tuab ntawm 0, 4-0, 6 hli, tab sis lub ru tsev zoo li no yuav tsis suav tias yog qhov ruaj khov tshaj plaws, txij li txheej txheej (nplooj ntawv) tau hloov pauv me ntsis txheeb ze rau ib leeg, tsis muaj teeb meem li cas lawv ntseeg tau. Tus kheej tapping screws nrog gaskets, tho qhov hauv lawv, yuav ncab cov qhov no, ua rau lawv lub ntsej muag zoo li, yog li ntawd, lub ru tsev yuav pib "taug kev".
Qhov siab ntawm daim ntawv sib txawv nws txawv ntawm 8-75 hli . Qhov sib txawv ntawm sab saud thiab qis ntawm ib nrab-nthwv dej tau tsim nyob rau theem ntawm kev tsim cov ntawv profiled. Cov ntawv txheeb phab ntsa uas siv rau kev tsim cov laj kab tsim nyog rau yuav luag txhua txoj haujlwm - txawm tias yog sab hauv, piv txwv li, thaum kho lub tsev rau khoom: rau lawv, qhov sib txawv no tsis mus dhau 1 cm. yam tsawg 2 cm.
Ntawm qhov kev sib tshuam ntawm daim ntawv vov tsev, qhov zawj tshwj xeeb tau tsim los txhawm rau tso dej ntau dhau.
Muab xam los
Qhov zoo tshaj, qhov muaj txiaj ntsig ntev ntawm daim ntawv profiled yog sib npaug rau nws qhov ntev kawg. Rau kev suav kom raug dua, thaj tsam ntawm lub ru tsev raug ntsuas thiab suav. Tom qab ntawd cov txiaj ntsig tau txais- suav nrog qhov ntev thiab dav ntawm lub ru tsev kom rov npog (lossis "los ntawm kos") tau faib los ntawm qhov muaj txiaj ntsig zoo tiag tiag ntev thiab dav ntawm daim ntawv profiled. Hauv qhov no, kev sib tshooj tau muab coj los rau hauv tus account - nws tsis yooj yim sua kom muab cov ntawv txheeb rau ib leeg, nruj me ntsis raws cov ntug.
Ua piv txwv - tus lej tiag tiag ntawm daim ntawv theej tawm, siv rau qhov chaw nyob ruaj khov ntawm lub nthab ntoo los ntawm nag, daus, lawg thiab cua, rau lub ru tsev . Cia peb hais qhov dav ntawm lub ru tsev nqes hav yog 12 m. Raws li cov ntaub ntawv kho, qhov tseem ceeb ntawm 1, 1 (+ 10% rau qhov dav ntawm daim ntawv) raug coj mus, coj mus rau hauv tus account yuav suav nrog kev tsim qee yam tus nqi pov tseg tsim thaum txiav cov ntawv. Ua raws li qhov kev hloov kho no, qhov dav ntawm txoj kab nqes hav yuav yog 13.2 m.
Thaum kawg txiav txim siab tus naj npawb ntawm cov ntawv theej tawm ntawm cov ntawv profiled, qhov txiaj ntsig tau muab faib los ntawm qhov ntsuas dav siv tau. Yog tias siv daim ntawv tshaj lij nrog NS -35 npav cim - 1 m dav - tom qab ntawd, suav nrog kev suav sau, tsawg kawg 14 nplooj ntawv yuav tsum tau ua.
Txhawm rau txiav txim siab tus naj npawb ntawm cov ntawv txheeb raws li lawv cov xwm txheej tag nrho, peb muab cov lej los ntawm qhov ntev thiab dav ntawm daim ntawv
Piv txwv li, 6-meter daim ntawv ntev ntawm NS-35 profile muaj qhov dav ntawm ib lub 'meter' thiab ib lub hlis twg. Hauv qhov no, nws yog 105 m2.
Yog hais tias lub ru tsev yog gable, tom qab ntawv suav nrog txhua qhov nqes hav sib cais. Nrog tib qhov nqes hav, qhov no yuav tsis nyuaj rau suav. Ib lub ru tsev nrog qhov nqes hav ntawm ib lub kaum sab xis sib txawv rau lub qab ntug yuav ua rau me ntsis nyuab dua rau kev suav - cov pwm thiab cov plaub fab tau muab cais cais rau txhua qhov nqes hav.
Yog tias koj tsis muaj sijhawm los ua tus qauv ntsuas koj tus kheej, koj tuaj yeem siv lub laij lej online, tsab ntawv uas suav nrog kev suav rau qhov ntsuas ntawm lub ru tsev ntawm kev teeb tsa. Nws yog qhov zoo dua los suav cov ntawv txheeb rau 4-pitched thiab ntau qib ru tsev nrog kev npaj tsis raug ntawm cov ntawv uas siv cov ntawv sau rau ntawm qhov chaw dua li suav los ntawm kos koj tus kheej.
Dab tsi los xav txog thaum xaiv cov ntawv?
Ua ntej tshaj plaws, tuab ntawm cov hlau rau lub ru tsev yuav tsum yog qhov siab tshaj plaws. Nws yog ib qho ntawm cov yam ntxwv tseem ceeb uas kev pab lub neej thiab lub zog ntawm lub ru tsev nyob . Qhov zoo tshaj plaws, nws yog millimeter steel uas ua tau zoo tiv thaiv kev cuam tshuam. Rau kev tsim tsheb, tsis txhob siv cov ntawv txheeb, cov ntawv hlau yooj yim nrog lub tuab ntawm 2-3 hli tau xaiv, uas tso cai rau txhua lub tsev tso tsheb hlau hlau sawv rau ntau dua ib xyoo lawm.
Raws li SNiP, qhov tuab ntawm 0.6 hli tuaj yeem xaiv rau kev tsim kho ntiag tug ntawm thaj chaw uas muaj kev ntseeg ruaj khov los ntawm cov neeg txawv . Nyob rau hauv rooj plaub ntawm chav tsev thiab tsim tsev, siv 1 hli hlau.
Ib qho tuab tuab tau siv rau ntawm lub ru tsev nrog cov txheej txheem lathing ua tau zoo raws li qhov muaj zog tag nrho ntawm tag nrho cov qauv - cov theem ntawm rafter thiab lathing boards / kab teeb yuav tsum tsis pub tshaj 60 cm, uas txhais tau tias tsis muaj qhov taw tes hauv kev siv cov hlau tuab tshaj li 1 hli.
Wave qhov siab yuav ua lub luag haujlwm tseem ceeb hauv kev muaj zog ntawm lub ru tsev . Txawm hais tias qhov no tsis yog panacea rau kev thauj khoom ntau dhau, piv txwv li, los ntawm coob leej neeg uas tau mus rau lub ru tsev kom pab lub ru tsev, nthwv dej ntawm 2 cm lossis ntau dua yog qhov kev daws teeb meem ib ntus. Qhov tseeb yog tias daim ntawv profiled khoov nyuaj dua, nws cov nyiaj pab them ib nrab rau cov hlau khoov. Txawm li cas los xij, qhov txwv tsis pub nqa khoom, piv txwv li, los ntawm tus neeg ua haujlwm hnyav uas tau hnav lub khau uas muaj pob taws khov heev thiab taug kev yooj yim ntawm lub ru tsev, yuav yooj yim ntxuav cov nthwv dej.
Ib nplooj ntawv ntev ntawm 4 m yog qhov tsim nyog rau txoj kab nqes uas nws qhov dav tsawg dua qhov ntev no . Kev suav yuav tsum tau ua rau hauv tus as khauj hlau, txhua sab sawb ntawm qhov uas yuav txo qee qhov dav ntawm txoj kab nqes uas npog los ntawm daim ntawv profiled. Mus txog 30 cm tuaj yeem mus rau hauv qab toj roob hauv pes - qhov tseem ceeb yog qhov qis dua ntawm cov ntawv sau tau dai rau ntawm armopoyas nrog Mauerlat, tiv thaiv ib feem ntawm phab ntsa ntawm lub tsev los ntawm kev los nag. Rau qhov nqes mus txog 6 m, daim ntawv 6-meter yog qhov tsim nyog. Rau qhov nqes hav sib txawv hauv qhov dav dav - txog 12 m - cov ntawv ntawm qhov ntev sib xws yog qhov tsim nyog; daim ntawv ntev dua, qhov hnyav dua nws yog rau nruab. Kev daws teeb meem, muab rau kev teeb tsa ntawm cov ntawv uas haum rau qhov dav ntawm txoj kab nqes, tso cai rau koj kom tshem tawm cov kab rov tav - tag nrho cov kab txaij yog ib leeg nkaus xwb.
Hom npog ntawm lub rooj tsavxwm corrugated
Yas coated decking zoo li cog lus nyob rau hauv cov nqe lus ntawm kev ua haujlwm ntev. Yog tias muaj pes tsawg leeg tiv taus qhov tsis zoo ntawm cov cua sov ntau thiab hluav taws xob ultraviolet, thiab tseem tsis tawg thaum txias, tom qab ntawv cov ntawv ntawd yuav siv sijhawm ntev - txog 40 xyoo.
Cov hlau yooj yim, uas yog "steel nqig", tsim nyog tau txais kev saib xyuas tshwj xeeb . - stewed ntawv hlau, muaj peev xwm ua haujlwm tsis tau 3-5, tab sis txog 30 xyoo thaum txheej tiv thaiv tev tawm.
Nws qhov tseem ceeb yog cov pa roj ntau dhau, suav nrog cov pa oxygen, tau raug tshem tawm ntawm cov hlau khaws cia tau ntev nyob hauv lub xeev yaj, thiab cov hlau no muaj qhov ntom ntom me ntsis, muaj zog ntau dua thiab tiv taus xeb.
Cov thev naus laus zis thiab cov qauv uas ua rau nws muaj peev xwm los tsim "nyob ntsiag to" hlau tau ua pov thawj los ua lub zog loj. GOST cov qauv rau kev nrum thiab dov hlau tau hloov pauv nrog rau thev naus laus zis . Kev tsim cov hlau tau nrawm dua - vim li ntawd, nws qhov ua tau ntev tau raug kev txom nyem. Xav txog qhov no, txheej txheej txheej hlau, suav nrog daim ntawv profiled, tau xaiv kom nws tsis ploj mus ntev thiab tsis hnav tawm ua ntej cov khoom siv los ntawm cov ntawv profiled tau raug nthuav tawm. Nws yog qhov muaj txiaj ntsig zoo los tshuaj xyuas lub ru tsev txhua rau rau lub hlis lossis ib xyoos rau tev ntawm txheej txheej tiv thaiv - thiab yog tias koj xav tias tsis xoob, ploj, rov ua dua tshiab siv cov xim pleev xim rau xeb thiab polymer (hluavtaws) xim.
Lub thickness ntawm txhua txheej txheej yog tsawg kawg 30 microns: txheej tuab dua yuav tev tawm sai dua, thiab cov hlau yuav xeb hauv ob peb hnub tom qab txheej txheej tiv thaiv raug tshem tawm tag. Qee cov kws tshaj lij siv cov ntawv ua cov ntawv galvanized, tab sis zinc tau yooj yim corroded los ntawm cov kua qaub, cov seem uas (sulfurous, nitrogenous, thee) ib txwm muaj nyob hauv nroog nag (nag). Rau lub ru tsev, txheej txheej zinc - txawm hais tias nws tsis ntshai dej li ntawd - tsis siv.
Cov tuam txhab muab cov ntaub ntawv npaj ua tiav rau kev ua haujlwm vov tsev tshaj tawm qhov kev pom zoo ua haujlwm-15-40 xyoo . Qhov tsawg kawg ntawm kev pab lub neej ntawm lub ru tsev yog siv tsis zoo ntawm lub ru tsev - piv txwv li, poob ntawm cov cuab yeej siv tes ua rau khawb ntawm txheej, ua kom tsis nco qab thiab yam tsis tsim nyog (tshwj xeeb yog hlau) ntawm lub ru tsev - yuav raug txo kom tsawg xwb. xyoo. Lawv tsis lees paub los ua pov thawj "lub neej" ntev dua ntawm cov ntawv sau, tsis hais lub zog thiab cov hlau zoo li cas, nws tsis tuaj yeem "nyob" 100 lossis ntau xyoo.
Cov ntawv hlau hlau, ntxiv rau nws qhov hnyav, tuaj yeem tiv taus qhov hnyav ntawm cov daus, cov neeg hla lub ru tsev thaum lub sijhawm nws kho (thiab kho lub sijhawm), nrog rau cov cuab yeej tso rau hauv qhov chaw ua haujlwm. Nyob rau tib lub sijhawm, lub ru tsev yuav tsum tau khov kho, muaj peev xwm tuav tau tag nrho cov kev cuam tshuam no ib zaug.
