Insimbi yokuzithinta
Izikulufu zokuphahla
Akusekho Iimbobo Zomtjhayeli. Bhora nje begodu utjhayele.
Yenziwe bona iphile isikhathi eside ukudlula uphahla ngokwalo.
I-Taper-Sharp Tip. Ukubhora nokubophelela ngesikhathi sinye
I-Sinsun Self-Tapping Roofing Screws: Engineering ukusebenza okuhlala isikhathi eside
I-Sinsun Self-Tapping Roofing Screws yenzelwe ukwenza ukubeka uphahla lwensimbi kube msinyana begodu kube lula.
Zinendawo yokubhora eqinileko edlula emashidini wensimbi ngaphandle kokubhora ngaphambilini, begodu zifakwe i-Al-Zn nofana i-PVDF ukuvikela ekuruseni.
I-EPDM washer ehlanganisiweko iqinisekisa ukuvala okungangeni amanzi emazingeni womtjhiso ahlukahlukeneko, ukusuka ku-40°C ukuya ku-120°C. Lokhu kuvikela ubujamo bezulu isikhathi eside.
Iinkulufu lezi zenzelwe ukubamba amashidi wensimbi ahlanganisiweko kanye namaphaneli wokuvikela ezakhiweni zensimbi.
Zitholakala ngobubanzi obusuka ku-#12 ukuya ku-14mm kanye nobude obusuka ku-25mm ukuya ku-100mm. Ukuze zibe namandla wokubamba nokusebenza kuhle, kufuze zibe ngama-20mm ukutjhinga.
- Ukuthembeka okuphezulu kokutjhayela nokufakwa kwe-Torque ephezuluIdizayini yehloko yewatjhi ye-hex iqinisekisa ukuvumelana okukhulu nama-socket driver kanye nama-impact wrenches, ukuqeda ukuphuma kwe-cam nokukhumula. Isikrufu ngasinye sibekwe phasi nge-torque ephezulu, ngalokho isikulufu ngasinye sifinyelela amandla wokubopha aklanyelwe nokusebenza kokuvala.
- Ukuvikelwa kokugqwala okwenziwe ngobunjiniyela kweendawo ezithilekoSinikela ngeentlobo ezihlukahlukeneko zokuqeda ukugqwala, kusukela ekugcotshweni okujwayelekileko kanye ne-Dacromet. Lokhu kukuvumela bona ukhethe izinga elifaneleko, elibizako lokuvikeleka ekuguqukeni kwezulu, ukuvezwa kwamakhemikhali, nofana ukufafazwa kwetshwayi ngokuya ngendawo yephrojekthi yakho neemfuneko zesikhathi sokuphila.
- Isivalo esithembekileko, sesikhathi eside esivikela ubujamo bezuluIwashi yokuvala ye-EPDM ehlanganiswe nefemu yenzelwe ukugandeleleka ngokufanako, okwenza bona kube nesithiyo esingangenwa mamanzi. Ihlala iqinile emazingeni womtjhiso aphezulu (-40°C ukuya ku-120°C), igcina isivalo ematjhumini weminyaka yokutjhisa nokuvezwa kwe-UV ukukhandela ukuvuza.
- Ukungena okuqinisekisiweko nokubamba amandlaNgeenkhetho ze-Tek point ezihlukaniswe ngokucacileko (isib., i-Tek 4, i-Tek 5), iinkulufu zethu zinikela ngekghono lokungena elingalindelekileko eentweni zensimbi. Lokhu kususa ukuqagela ngaphandle kokukhetha, ukuqinisekisa bona isikulufu singabhora phakathi kwepahla yoke begodu sifinyelele ubuncani bama-20mm ukufakwa ngaphakathi kwe-purlin ukuthola amandla woke wokudonsa.
| Ipharamitha | Ukucaciswa | Imininingwana / Amanothi |
| Umhlobo weThredi | Ukuzithepha, i-AS 3566 iKlasi 4 nofana okufanako | Iphuzu lokubhora elibukhali lokubhora, ukuthepha, nokubophelela ngasikhathi sinye. |
| Isitayela sehloko | Ihloko ye-Hex Washer (HWH) | Umhlobo weDrayivu: Ihloko enama-hexagonal eyenzelwe ukunamathiselwa kwesokhethi nofana i-nut driver, enikela ngokudluliswa kwe-torque ephezulu nokunciphisa ukuphuma kwe-cam. |
| Umtjhini wokuvala | Irabha ye-EPDM ene-High-Density, ehlanganiswe ne-Steel Washer | Iqinisekisa isivalo esiqinileko, esingangenwa mamanzi nesimo sezulu, esijamelana nokuvezwa kwe-UV nokutjhuguluka kwamazinga womtjhiso (-40°C ukuya ku-+120°C). |
| Iinsetjenziswa eziqakathekileko | Insimbi enamandla khulu, eneKhabhoni encani (iGreyidi 1022A nofana ngcono) | Inikela ngamandla atlhogekako wokuqina nokuqina okungaguqukiko kwephuzu lokubhora. |
| Ukuqeda ukugqwala | Inketho yoku-1: I-Galvanized (Ifakwe nge-Zinc) | Ukujamelana nokugqwala okujayelekileko kokusetjenziswa okujayelekileko. |
| Inketho yesibili: I-Dacromet (Zn-Al Chromate Coating) | Ukugqwala okuphezulu nokujamelana namakhemikhali ngaphandle kobungozi bokuphuka kwe-hydrogen. | |
| Indlela yesi-3: I-Galvanized etjhisako | Igcotshwe khulu ukuvikela ukugqwala eendaweni ezimbi. | |
| Inketho yesi-4: Ihloko enemibala (isib., i-PVDF/i-Polyester) | Ifakwe phezu kwesikhumba esisekelako (isib., esifakwe i-galvanized) ukufanisa umbala nobujamo bezulu obungezelelweko. | |
| Ubukhulu obujayelekileko | Ububanzi: #12 (5.5mm), #14 (6.3mm), njll. | Ubude: Ngokuvamileko busuka ku-25mm (1") ukuya ku-100mm (4") nofana ngokwesiko. Ubude bukhethwa ngokuya ngobukhulu bezinto ezipheleleko (iphaneli + i-purlin). |
| Amazinga wokuSebenza | Ikhambisana namazinga webubulo afaneleko wokujamelana nokuphakanyiswa komoya nokuqina kokudonsa. | |
Ukufakwa kwephahla lensimbi nebonda: Ukubophelela amashidi wensimbi, amaphaneli we-trapezoidal, namaphaneli wesangweji ahlanganisiweko kuma-purlins wensimbi nofana ama-girt ezakhiweni zezebubulo, zezokuthengisa, nezezokulima.
Umsebenzi wokubuyisela kabutjha nokulungisa: Ukuqinisa amashidi amatjha wensimbi phezu kwezakhiwo ezikhona nofana ukubuyisela izinto zokubophelela ezihlulekileko, ukunikela ukubamba okuthembekileko ngaphandle kokutlhoga imigodi ebhojwe ngaphambilini esisekelweni.
Ukunamathisela Iinsetjenziswa zokuphahla: Ukufaka izinto ezisekelako ezifana nama-ridge caps, ama-flashing, ama-gutter, kanye namabhakede wokufaka amaphaneli welanga ngqo emaphepheni wephahla wensimbi nofana amafreyimu.
Isici esiqakathekileko esihlanganisiweko yi-washer yokuvala (ngokuvamileko i-EPDM), ecindezela lokha nayifakwako ukwenza isivalo esingangenwa mamanzi esizungeze isikulufu, ukukhandela ukuvuza. Nayihlanganiswe nama-coating ajamelana nokugqwala, iinkulufu lezi zinikela ngesisombululo esipheleleko esiqinisekisa ukuthembeka kwesakhiwo, ukuvikeleka ebujameni bezulu, nokuqina kwehlelo loke lokuphahla.

Umbuzo: Ingabe kutlhogeka bona ngibhore imigodi ngaphambilini lokha nangisebenzisa iinkulufu zokuphahla ezizithephako?
A: Awa, lokho msebenzi omkhulu wesikrufu. Isikrufu sokuphahla esizibophelelako sifakwe indawo yokubhora (evamise ukuhlukaniswa njenge-Tek 4, Tek 5, njll.) engena ngaphakathi kwephepha lokuphahla lensimbi kanye ne-purlin yensimbi engaphasi ngesinyathelo sinye. Lokhu kuqeda isidingo sokwenza umsebenzi ohlukileko wangaphambi kokubhoboza, ukonga isikhathi esikhulu sabasebenzi neendleko. Qinisekisa bona umhlobo wephuzu lesikrufu ulinganiselwe ukujiya okupheleleko kwezinto ozibophelelako.

Umbuzo: Iwatjhi yokuvala ivimbela njani ukuvuza, begodu ihlala isikhathi esingangani?
A: Iwashi yokuvala, evamise ukwenziwa ngerabha ye-EPDM, ihlanganiswe unomphela ekhanda lewashi lesikrufu. Lokha isikrufu nasiqhutshwa ukuya ku-torque efaneleko, iwashi iyagandeleleka ukwenza i-gasket eragela phambili, engangeni amanzi ezungeze i-shank yesikrufu. Ama-washer we-EPDM wekhwalithi enzelwe ukugcina ukuthamba nokuvala ukusebenza emazingeni womtjhiso ahlukahlukeneko (ngokuvamileko -40°C ukuya ku-+120°C) begodu ajamelana nokuwohloka kwe-UV, okunikela ukuvala okuthembekileko kwesikhathi sokuphila kophahla (kanengi iminyaka ema-20+).

Umbuzo: Ngingakhetha njani ubude besikrufu esifaneleko sephrojekthi yami yokuphahla yensimbi?
A: Umthetho wesithupha uthi: Ubude besikrufu = Ubukhulu bephepha lensimbi + Ubukhulu be-Purlin + Ukufakwa okuncani. Into eqakathekileko kuqinisekisa bona intambo yesikrufu ihlangana ne-purlin yesakhiwo ubuncani bama-20mm (3/4 intshi). Ukwenza isibonelo, malungana nephepha lophahla elingu-0.5mm phezu kwe-purlin engu-2.0mm, udinga okungenani isikulufu eside esingu-20mm + 2.5mm = 22.5mm, ngalokho isikulufu esingu-25mm nofana esingu-30mm kungaba yinto ejwayelekileko. Qinisekisa ngaso soke isikhathi ngeenhlathululo zobunjiniyela.

Umbuzo: Uyini umehluko phakathi kwezikulufu ezijayelekileko ezifakwe i-VDF nezifakwe i-PVDF zokufulela?
Ipendulo: Umehluko ulele ekujamelaneni nokugqwala, ukuqina, kanye nobuhle. I-Standard Galvanized (Zinc) inikela ngokuvikeleka okuhle, nge-hot-dip galvanized coatings enikela ukuphila isikhathi eside. I-PVDF Coating yi-polymer coating ephezulu efakwe phezu kwesisekelo esine-galvanized, enikela ngokujamelana okuhle khulu nokufiphala kombala, ukutjhwaba, kanye namakhemikhali aqinileko. Yikhetho elikhethwako lamaphrojekthi adinga ukunzinza kombala kwesikhathi eside nokuqiniseka kobujamo bezulu.

Umbuzo: Kufanele ngenzeni nangabe isikulufu sophahla siqhutshwa khulu nofana siqhutshwa ngaphasi?
A: Zombili iimeko zibeka engozini isivalo esivikela ubujamo bezulu. Ukuqhutshwa khulu: I-washer icindezelwe khulu nofana ilimele; susa isikulufu, zalisa umgodi nge-sealant, bese ufaka isikulufu esitjha eduze. Ukuqhutshwa ngaphasi: I-washer ayigandelelwe ngokupheleleko; vele uqhube isikulufu sibe sebujameni obufaneleko. Ukusebenzisa i-drill ene-clutch elungisekako kuqakathekile ekukhandeleni ukutjhayela khulu.
