I-scaffold ye-portal iyi-scaffold yepayipi lensimbi ejwayelekile eyakhiwe ngohlaka lwe-portal, ukwesekwa okuphambeneyo, induku yokuxhuma, ibhodi le-scaffold ye-buckle noma uhlaka oluvundlile, ingalo yokukhiya, njll., bese ifakwe induku yokuqinisa evundlile, i-cross bracing, induku yokushanela, induku yokuvala, i-bracket kanye nesisekelo, futhi ixhunywe nesakhiwo esiyinhloko sesakhiwo ngezingxenye ezixhumanisa udonga. I-scaffold yepayipi lensimbi ye-portal ingasetshenziswa hhayi nje kuphela njenge-scaffold yangaphandle, kodwa futhi njenge-scaffold yangaphakathi noma i-scaffold egcwele.

inhloso

1. Isetshenziselwa ukusekela uphahla olusefomini yezakhiwo, amahholo, amabhuloho, ama-viaducts kanye nemigudu noma njengohlaka oluyinhloko lokusekela ifomu lokundiza.

2. Yenza izisekelo zegridi zangaphakathi nezangaphandle zezakhiwo eziphakeme.

3. Ipulatifomu yokusebenza enyakazayo yokufaka i-electromechanical, ukulungisa i-hull kanye neminye imisebenzi yokuhlobisa.

4. Indawo yokuhlala yesikhashana, indawo yokugcina impahla noma ishede lokusebenzela lingakhiwa ngokusebenzisa i-portal scaffold kanye ne-roof truss elula.

5. Isetshenziselwa ukusetha ihholo lesikhashana kanye nenkundla yokuma

I-fastener scaffold inezici zokuhlukaniswa okuguquguqukayo, ukuthuthwa okulula kanye nokusetshenziswa okunamandla. Ngakho-ke, isetshenziswa kabanzi eShayina. Kubunjiniyela be-scaffold, ukusetshenziswa kwayo kubalwa ngaphezu kuka-60%. Yi-scaffold esetshenziswa kakhulu futhi esetshenziswa kabanzi njengamanje. Kodwa-ke, lolu hlobo lwe-scaffold alunaso isiqinisekiso sokuphepha esibi kanye nokusebenza kahle kokwakha okuphansi, futhi alukwazi ukuhlangabezana nezidingo zokuthuthukiswa kwamaphrojekthi okwakha amakhulu.

Kunezinhlobo eziningi zemininingwane kanye nosayizi wezingxenye eziyinhloko

Kunezinhlobo eziningi zemininingwane nosayizi bezicafu zesango emhlabeni wonke, kufaka phakathi amayunithi aphesheya kanye namayunithi okulinganisa aseBrithani. Isibonelo, ububanzi bohlaka lwesango lwe-1219 ngeyunithi yesiNgisi bungu-4 '(1219mm) kanti ukuphakama kungu-6′ (1930mm), kanti ububanzi bohlaka lwesango lwe-1219 ngeyunithi yamazwe ngamazwe bungu-1200 mm kanti ukuphakama kungu-1900 mm. Ububanzi besango lezinkampani zezicafu zezinye izizwe buhlanganisa ikakhulukazi u-900, 914, 1200 kanye no-1219 mm. Kunezinhlobo eziningi zokuphakama kwesango, okwakha isethi yesistimu.

Izincazelo zomkhiqizo zabakhiqizi abaningana eShayina nazo aziguquguquki kakhulu. Abanye balingisa izincazelo zomkhiqizo wangaphandle, kanti amanye amayunithi ocwaningo lwasekhaya aklama isethi yesistimu ngokwawo. Amanye asebenzisa usayizi waseBrithani kanti amanye asebenzisa usayizi weyunithi yamazwe ngamazwe. Isibonelo, ububanzi be-gantry bungu-1219mm ohlelweni lwesiNgisi, u-1200mm ohlelweni lwamayunithi lwamazwe ngamazwe, kanti isikhala sohlaka singu-1829mm no-1830mm ngokulandelana. Ngenxa yalezi zilinganiso ezahlukene, i-gantry ayikwazi ukusetshenziselwana. Njengesinye isibonelo, kunezincazelo zokuphakama ezingaphezu kweziyisishiyagalombili nosayizi be-gantry, futhi kukhona nosayizi abaningi besikhala phakathi kwezikhonkwane zokuxhuma, okuholela ekucacisweni okuningi kanye nezinhlobo zokubopha okuphambeneyo.

Kungenxa yobubanzi bosayizi ukuthi sidinga amabhizinisi anamandla njengathi ukuze sihlangabezane nezidingo ezahlukene zamakhasimende. Siyakwamukela ukubuza, sicela usithumelele i-imeyili ukuze uthole imininingwane.
