I-portal scaffold yi-standard standardized steel pipe scaffold eyenziwe yi-portal frame, cross support, connecting rod, buckle scaffold board okanye straight frame, lock arm, njl.njl., ize ixhotyiswe nge-horizontal reinforcement rod, cross bracing, sweeping rod, sealing rod, bracket and base, kwaye iqhagamshelwe kwisakhiwo esiphambili ngeendawo ezidibanisa udonga. I-portal steel pipe scaffold ingasetyenziswa kungekuphela nje njenge-scaffold yangaphandle, kodwa ikwasetyenziswa njenge-internal scaffold okanye i-full scaffold.

injongo

1. Isetyenziselwa ukuxhasa uphahla kwisakhiwo sezakhiwo, iiholo, iibhulorho, ii-viaducts kunye neetonela okanye njengesakhelo esiphambili senkxaso yesakhiwo sesakhiwo esibhabhayo.

2. Yenza izikhonkwane zegridi zangaphakathi nezangaphandle zezakhiwo eziphakamileyo.

3. Iqonga lokusebenza elinokushukunyiswa lokufakelwa kwe-electromechanical, ukulungiswa kwe-hull kunye neminye imisebenzi yokuhombisa.

4. Indawo yokuhlala yexeshana, indawo yokugcina impahla okanye ishedi yokusebenzela inokwenziwa ngokusebenzisa i-portal scaffold kunye ne-roof truss elula.

5. Isetyenziselwa ukuseta iholo yexeshana kunye nenkundla enkulu

I-fastener scaffold ineempawu zokuqhaqha eziguquguqukayo, ukuthuthwa okulula kunye nokusebenza ngokubanzi. Ke ngoko, isetyenziswa kakhulu eTshayina. Kwinjineli ye-scaffold, ukusetyenziswa kwayo kungaphezulu kwama-60%. Yeyona scaffold isetyenziswa kakhulu kwaye isetyenziswa kakhulu okwangoku. Nangona kunjalo, olu hlobo lwe-scaffold alunasiqinisekiso sokhuseleko esifanelekileyo kunye nokusebenza kakuhle kolwakhiwo, kwaye alunakwanelisa iimfuno zophuhliso lweeprojekthi zokwakha ezinkulu.

Kukho iinkcukacha ezininzi kunye nobukhulu bezinto eziphambili

Kukho iinkcukacha ezininzi kunye nobukhulu bee-scaffold ze-portal kwihlabathi liphela, kuquka iiyunithi zamazwe ngamazwe kunye neeyunithi zokulinganisa zaseBritane. Umzekelo, ububanzi besakhelo se-portal esingu-1219 kwiyunithi yesiNgesi yi-4 '(1219mm) kwaye ukuphakama yi-6′ (1930mm), kwaye ububanzi besakhelo se-portal esingu-1219 kwiyunithi yamazwe ngamazwe yi-1200 mm kwaye ukuphakama yi-1900 mm. Ububanzi be-gantry beenkampani ze-scaffold zangaphandle buquka ikakhulu i-900, 914, 1200 kunye ne-1219 mm. Kukho ubukhulu obuninzi bokuphakama kwe-gantry, okwenza iseti yenkqubo.

Iinkcukacha zemveliso zabavelisi abaliqela eTshayina nazo azingqinelani. Ezinye zixelisa iinkcukacha zemveliso zangaphandle, kwaye ezinye iiyunithi zophando zasekhaya ziyila iseti yenkqubo ngokwazo. Ezinye zamkela ubungakanani baseBritane kwaye ezinye zamkela ubungakanani beeyunithi zamazwe ngamazwe. Umzekelo, ububanzi be-gantry yi-1219mm kwinkqubo yesiNgesi, i-1200mm kwinkqubo yeeyunithi zamazwe ngamazwe, kwaye isithuba sefreyimu yi-1829mm kunye ne-1830mm ngokwahlukeneyo. Ngenxa yale milinganiselo yahlukeneyo, i-gantry ayinakusetyenziswa omnye komnye. Njengomnye umzekelo, kukho iinkcukacha zokuphakama ezingaphezu kwesibhozo kunye nobukhulu be-gantry, kwaye kukwakho nobukhulu besithuba phakathi kweepini zokudibanisa, okubangela iinkcukacha ezininzi kunye neentlobo ze-cross diagonal bracing.

Kungenxa yobubanzi bobukhulu obuhlukeneyo ukuba sidinga amashishini anamandla njengathi ukuze sihlangabezane neemfuno ezahlukeneyo zabathengi. Wamkelekile ukubuza, nceda usithumelele i-imeyile ukuze ufumane iinkcukacha.
