Kutheni IiProfayili zePhepha lokufulela zibalulekile
Uphahla lwemizi-mveliso lunokugubungela iindawo zokugcina iimpahla, iindibano zocweyo, amaziko okuvelisa, izakhiwo zokugcina, kunye nezinye izakhiwo ezinkulu. Izicwangciso zabo zophahla, ukuxhaswa kwenkxaso, iindlela zokuhambisa amanzi, kunye neemeko zokuvezwa ziyahluka. Iprofayili yephepha lokuphahla kufuneka isebenze kunye nezo nkcukacha zeprojekthi kunye nenkqubo yokufakela echaziweyo.
I-Corrugations kunye neembambo zibumba iphepha. Ngokuxhomekeke kwijometri yeprofayili kunye neenkcukacha ezipheleleyo, zinokuchaphazela indlela iphaneli ehamba ngayo phakathi kwenkxaso, indlela amashiti awelana ngayo, kunye nendlela amanzi ahamba ngayo eluphahleni. Ezi ziphumo azinakugwetywa ngegama leprofayile okanye ifoto yodwa. Ubukhulu beshiti, iipropathi zezinto eziphathekayo, izithuba zenkxaso, ukulungiswa, indawo yophahla, kunye neenkcukacha zofakelo nazo zibalulekile.
Kumaqela okuthenga, ukukhetha iprofayile kwangoko kunokunceda ukulungelelanisa uyilo lophahla, ukunduluka kobuninzi, iimfuno zoncedo, kunye nekowuteshini yomthengisi. Ikwakwenza kube lula ukuthelekisa unikezelo kwiinkcukacha ezifanayo. Xa amaxabiso entsimbi kunye neendleko zezinto eziphathekayo ziguquguquka, ukuthelekisa ukucaciswa kweprojekthi epheleleyo kunokuba luncedo ngakumbi kunokuthelekisa ixabiso leyunithi ngaphandle komxholo.
IiProfayili zamaza, iRib, kunye neTrapezoidal
IiProfayili zamaza okanye ezonakeleyo
Iprofayile yamaza ineentsimbi eziphindaphindiweyo ezigobileyo. Amaphepha enziwe ngamatye asetyenziswa kuluhlu lwezicelo zokuphahla, kwaye imveliso ekhethiweyo kufuneka ihambelane nesakhiwo kunye neemfuno zokufakela. Kwiprojekthi yoshishino, abathengi kufuneka baqinisekise ububanzi bekhava esebenzayo, ilungiselelo le-side-lap, ubude beshiti, indawo yokulungisa, kunye nokuhambelana neenkcukacha zephahla.
Iprofayili edibeneyo ingafanelana neprojekthi apho ifom yephepha elichaziweyo kunye nenkangeleko isebenza kunye noyilo lwephahla. Nangona kunjalo, igama elithi 'amaqokobhe' lilodwa alimxeleli umthengi imilinganiselo yephaneli, ukusebenza komthwalo, okanye ukufaneleka kokukhutshwa kwamanzi. Ezo nkcukacha kufuneka ziqinisekiswe ngokuchasene nemveliso yomthengisi kunye neemfuno zenjineli yeprojekthi.
Iiprofayili zeRibbed kunye neTrapezoidal
Iiphaneli ze-Ribbed okanye ze-trapezoidal zisebenzisa ukugoba okungaphezulu kwe-angular kuneprofayili ejikelezayo yamaza. Imilo yazo ingafanelana noyilo lophahla olubiza ipateni yembambo eyahlukileyo okanye ilungiselelo elithile lephaneli. Izithuba kunye nokuphakama kweimbambo kuyahluka ngokwemveliso, ngoko ke abathengi kufuneka bacele umzobo weprofayili kunokuba baqikelele imilinganiselo kwinkcazo yemveliso ngokubanzi.
Iqela leprojekthi kufuneka lijonge ukuba iphaneli ekhethiweyo ihambelana njani ne-purlins, i-side laps, iinkcukacha ze-ridge, i-eves, kunye nokungena kophahla. Iprofayile ebonakala ifanelekile kwikhathalogu inokufuna uhlengahlengiso kuyilo okanye izincedisi. Ukuba iprojekthi ichaza iprofayili ethile, qinisekisa ukuba umthengisi unokubonelela ngeprofayili kunye neenkcukacha ezihambelanayo zokufakela.
Abanye ababoneleli banikezela ngeefom zeprofayili ezongezelelweyo, kubandakanywa noyilo olumilise okwe-T okanye olunobume obufana no-V. Ubukho kunye neenkcukacha zixhomekeke kuluhlu lwemveliso. Ziphathe njengeeprojekthi ezikhethekileyo: cela umzobo, imilinganiselo, kunye nesikhokelo sofakelo, uze uthelekise noyilo oluvunyiweyo lophahla.
I Uluhlu lwemveliso ye-Roofing Sheet kunye Uluhlu lwePhepha lokuLawula uphahla lubonisa iinketho zokuphahla ezinokuphononongwa ngabathengi xa belungiselela ukucaciswa kweprojekthi.
Indlela yokuTshatisa iProfayili kwiSakhiwo soShishino
Ukukhethwa kweprofayili kufuneka kuqale ngoyilo lwephahla kunye nemiqobo yalo. Yabelana ngolu lwazi lulandelayo nenjineli yeprojekthi kunye nabo banokuba ngababoneleli ngaphambi kokuba ucele ikowuti.
Uyilo lophahla kunye noLungiselelo lweNkxaso
Qinisekisa isicwangciso sophahla, isalathiso sephaneli, inkxaso okanye uyilo lwe-purlin, kunye nayiphi na imida kubude bephepha okanye ukuthutha. Iprofayili kunye nemilinganiselo yephaneli kufuneka iququzelele kunye nesakhiwo. Musa ukucinga ukuba iprofayili ifanelekile kwisithuba senkxaso ethile ngaphandle kokuqinisekiswa kobunjineli.
Ukuba isakhiwo sinamacandelo amaninzi ophahla, iintlambo, izibane eziphahleni, ukuvuleka kwe-ventilation, okanye ezinye iindawo zokungena, zibandakanya oku kuphononongo lwesakhiwo. Ezi ndawo zinokuchaphazela ukusika kwepaneli, ukudanyaza, kunye neenkcukacha zofakelo.
I-Roof Slope kunye noLawulo lwaManzi
Indawo yophahla, iimeko zokuna kwemvula, indawo eyalathisa kuyo iiphaneli, iindawo ezidityanisiweyo, iigatha, nomgangatho wofakelo, zonke zinegalelo kulawulo lwamanzi. Iprofayili kufuneka ivavanywe njengenxalenye yenkqubo yophahla olupheleleyo. Buza umyili okanye umboneleli ukuba aqinisekise iinkcukacha ezicetywayo zomjikelo wecala kunye nesiphelo somjikelo, unyango lwe-eves, unyango lwe-ridge, kunye neemfuno ezidanyazayo zeprojekthi.
Iprofayili yephepha ngokwayo ayiqinisekisi ukuba uphahla luya kuba namanzi. Iinkcukacha ezivunyiweyo kunye nomba wofakelo oluchanekileyo, ngakumbi malunga neenguqu kunye nokungena.
Ukusetyenziswa kwesakhiwo kunye nokuVezwa
Indawo yokugcina impahla, indawo yokuvelisa, kunye nesakhiwo sokugcina unxweme sinokuba neemfuno ezahlukeneyo zeprojekthi. Qwalasela indawo esisebenza kuyo isakhiwo, ukuba sesichengeni sokufuma okanye iimeko ezidlekayo, ukufikelela kugcino, nazo naziphi na iimfuno zenkangeleko okanye umbala. Ezi ngqwalasela zinokuchaphazela kuphela ukhetho lweprofayili, kodwa kunye nezinto eziphathekayo kunye neenkcukacha zokugqoka.
Kwizakhiwo ezikufutshane neenkqubo zemizi-mveliso, cacisa ukuba ingaba uphahla lunokuba sesichengeni kwiikhemikhali, umsi, okanye ezinye iimeko ezijongene nesiza. Iqela leprojekthi kufuneka livavanye loo miqathango kwaye lichaze inkqubo efanelekileyo yemveliso.
Ukuphatha, uFakelo, kunye noLungiselelo
Qinisekisa ubude bamaphepha akhoyo, iimfuno zokupakishwa, amalungiselelo okothula, kunye nolandelelwano lokuhanjiswa. Iiphaneli ezinde zinokunciphisa inani lee-joints ezinqamlezayo kwezinye iiplani, kodwa ukuthutha kunye nokuphathwa kwendawo kufuneka kuthathelwe ingqalelo. Umthengisi kufuneka aqinisekise ukuba bubuphi ubude kunye neendlela zokupakisha ezikhoyo kwi-odolo.
Bandakanya indlela yokufakela kunye neemfuno zokuncedisa kuphononongo. I-Fasteners, i-washers, i-flashing, i-ridge pieces, kunye ne-trim ehambelanayo inokufuna ukulungelelaniswa kunye neprofayili ekhethiweyo kunye neengubo.
Iingqwalasela zeMathiriyeli kunye noKwaleka
Iprofayili yinxalenye enye kuphela yenkcazo yokuthenga. Abathengi bophahla lwemizi-mveliso kufuneka bachaze izinto ezisisiseko ezifunekayo, ukwambathisa, ukugqiba, umbala, imilinganiselo, kunye nemigangatho yeprojekthi esebenzayo.
Ngokomzekelo, abathengi banokuthelekisa i-galvanized, i-aluminium-zinc-coated, kunye nezinketho zokuphahla kwangaphambili apho zinikezelwa khona kwiprojekthi. Ukhetho olufanelekileyo luxhomekeke kwimeko-bume, iimfuno zoyilo, isicwangciso sokulondoloza, kunye neenkcukacha ezifanelekileyo. Musa ukuphatha amagama okwambathisa njengetshintshiselana okanye ucinge ukuba isambatho esithile sifanelekile kuyo yonke imeko yokuvezwa.
I iphepha lemveliso yophahla lwamazinki ngumzekelo omnye wokuphononongwa xa uthelekisa iinketho zamacangci. Abathengi kufuneka baqinisekise idatha yobugcisa bemveliso yangoku kwaye baqinisekise ukuba iinkcukacha ezidwelisiweyo zihambelana neemfuno zeprojekthi ngaphambi kokubeka iodolo.
Inkcazo epheleleyo inokuquka:
Umzobo weprofayili kunye nemilinganiselo
