I-portal scaffold iyisikafula sepayipi lensimbi elimisiwe elakhiwe ngohlaka lwengosi, ukwesekwa okuphambanayo, induku yokuxhuma, ibhodi lesikafula sebhantshi noma uhlaka oluvundlile, ingalo yokukhiya, njll., bese ihlonywa induku yokuqinisa evundlile, i-cross bracing, induku yokushanela, induku yokuvala, ubakaki nesisekelo, futhi ixhunywe nesakhiwo esiyinhloko sesakhiwo ngezingxenye zokuxhuma odongeni. I-scaffold yepayipi yensimbi ye-portal ingasetshenziswa hhayi nje njenge-scaffold yangaphandle, kodwa futhi njenge-scaffold yangaphakathi noma i-scaffold egcwele.

inhloso

1. Isetshenziselwa ukusekela uphahla ku-formwork yezakhiwo, amahholo, amabhuloho, ama-viaducts nama-tunnels noma njengohlaka oluyinhloko lokusekela i-formwork endizayo.

2. Yenza izikafula zegridi zangaphakathi nezangaphandle zezakhiwo eziphakeme.

3. Isiteji sokusebenza esinyakazayo sokufakwa kwe-electromechanical, ukulungiswa kwe-hull kanye neminye imisebenzi yokuhlobisa.

4. Indawo yesikhashana yendawo yokulala, indawo yokugcina izinto noma ishede lokusebenza lingakhiwa kusetshenziswa isikafula sephothali kanye ne-roof truss elula.

5. Isetshenziselwa ukusetha ihholo nesitendi sesikhashana

I-Fastener scaffold inezici ze-disassembly eguquguqukayo, ezokuthutha ezilula kanye nendawo yonke eqinile. Ngakho-ke, isetshenziswa kabanzi eChina. Ebunjiniyela be-scaffold, ukusetshenziswa kwayo kubalwa ngaphezu kwama-60%. Kuyi-scaffold esetshenziswa kakhulu futhi esetshenziswa kakhulu njengamanje. Kodwa-ke, lolu hlobo lwe-scaffold lunesiqinisekiso esibi sokuphepha kanye nokusebenza kahle kokwakhiwa okuphansi, futhi alukwazi ukuhlangabezana nezidingo zokuthuthukiswa kwamaphrojekthi wokwakha imali.

Kunezincazelo eziningi kanye nosayizi bezingxenye eziyinhloko

Kukhona ukucaciswa okuningi nosayizi bezikhafula zephothali emhlabeni wonke, okuhlanganisa amayunithi wamazwe ngamazwe kanye namayunithi okulinganisa aseBrithani. Isibonelo, ububanzi bohlaka lwephothali engu-1219 kuyunithi yesiNgisi ngu-4 '(1219mm) nobude bungu-6′ (1930mm), futhi ububanzi befreyimu yephothali engu-1219 kuyunithi yamazwe ngamazwe ngu-1200 mm nobude bungu-1900 mm. Ububanzi be-gantry yezinkampani zakwamanye amazwe ikakhulukazi zibandakanya u-900, 914, 1200 kanye no-1219 mm. Kunezilinganiso eziningi zobude be-gantry, okwakha isethi yesistimu.

Ukucaciswa komkhiqizo wabakhiqizi abaningana e-China nakho akuhambisani kakhulu. Abanye balingisa ukucaciswa kwemikhiqizo yangaphandle, kanti amanye amayunithi ocwaningo lwasekhaya aklama isethi yesistimu ngokwawo. Abanye bathatha usayizi waseBrithani kanti abanye bathatha usayizi weyunithi yamazwe ngamazwe. Isibonelo, ububanzi be-gantry bungu-1219mm ohlelweni lwesiNgisi, 1200mm ohlelweni lwamayunithi ngamazwe ngamazwe, futhi ukuhlukaniswa kozimele ngu-1829mm no-1830mm ngokulandelanayo. Ngenxa yalobu bukhulu obuhlukahlukene, i-gantry ayikwazi ukusetshenziswa komunye nomunye. Njengesinye isibonelo, kunezicaciso zobude obungaphezu kwesishiyagalombili nosayizi be-gantry, futhi kukhona nosayizi abaningi bezikhala phakathi kwezikhonkwane zokuxhuma, okuholela ekucacisweni okuningi kanye nezinhlobonhlobo ze-cross diagonal bracing.

Kungenxa yokuthi kungenxa yobubanzi obuningi bosayizi esidinga amabhizinisi anamandla njengathi ukuze ahlangabezane nezidingo ezahlukahlukene zamakhasimende. Siyakwamukela ukubuza, sicela usithumele i-imeyili ukuze uthole imininingwane.
