I-staffolding inokudlala indima ethile yokhuselo, kodwa ukukhetha ukuphakama kwawo kufuna ingqalelo, ukuze ikhuseleke ngakumbi. Ngapha koko, zininzi izinto eziphakamileyo zokufudumeza, ekufuneka zikhethwe, ukuze ukhethe ukuphakama kwesakhiwo?
Kukho imigangatho eliqela yokubala ukuphakama ngaphandle kokuphakama kwe-scaffold:
Okokuqala, ukuphakama kokufakwa kwe-scaffold ziimitha ezingama-25-50, kunye nombhobho we-pitan of i-pire kufuneka womeleze uzinzo lupheleleyo lwe-scaffold. Umzekelo, kuyimfuneko ukuqhubeka nokubonelela ngenkxaso ye-desissor ye-deceudinal, nyusa inkxaso yase-Shear, enyusa amandla eentsika zodonga, kwaye unike inkxaso-mali engaphezulu kwe-40m kwiindawo ezinomoya. Ukujonga amandla okuqhuba phezulu kwe-vortex yomoya, unxibelelwano oluthe tyaba kufuneka lubonelelwe.
Okwesibini, ubalo lwe-scaffold kufuneka luhambelane nemigaqo efanelekileyo yenkcazo ye-scaffold kwaye uvunywe ngumntu ophethe inkampani.
Okwesithathu, xa ukuphakama kokukhula kudlula iimitha ezingama-50, i-scaffold inokomelezwa nge-bipolar okanye i-CTTE ikhutshiwe. Isakhiwo sescreedding kunye ne-beam siphakanyisiwe sonke ubude besakhiwo, kunye nenxalenye yomthwalo idluliselwa kwisakhiwo kwi-scaffold. Okanye sebenzisa ukwakhiwa kwento yokuqhubela phambili isikhephe ngasinye se-scalever kwi-cantilever kunye nesakhelo, ukwandisa kwisakhiwo, uyilo kwaye ubale.
Okwesine, i-scaffold kufuneka ikhule ekuphakameni okuthile ukuthintela ingozi yokhuseleko, kodwa ukuphakama kolwakhiwo akupheleli kukuphakama kwesakhiwo. Ke ngoko, ukuphakama kwecawa kufuneka kubalwe ngaphakathi koluhlu oluthile. Dibana neemfuno eziphezulu zeqela lokwakha.
Kwisabelo kwi-quota, umgama wenyathelo lokutsala kwe-statshi ithathwa njenge-1.2m, kunye nomgama wenyathelo lomgama wokuhlobisa uthathwa njenge-1.8m. Ukuphakama kwesakhiwo kuqala kwindiza apho kwakhiwa khona indawo apho kwakhiwa khona ibala kwindawo ephezulu yeprojekthi ekufuneka igqityiwe. Yahlula-hlula ukuphakama kwesakhiwo somgama. Ukuba i-quotient ifunyenwe linani elipheleleyo, emva koko thabatha 1; Ukuba i-quotient ifunyenwe ayisiyo malini, inani emva kokuba inqaku lokugqibela lilahliwe kwaye kuphela inxalenye ye-akhawunti ithathiwe. Umzekelo: IProjekthi yeMigangatho emithathu yokuHlala, ukusuka kumgangatho wangaphandle ukuya eluphahleni, ukuphakama kungu-10m. Emva koko i-10m / 1.8m = 5.56, inani lamanyathelo ngamanyathelo ama-5; Ukwakha udonga oluphakamileyo lwe-3.6m, i-3.6m / 1.2 = 3, kunye nenani lamanyathelo yi-3-1 = amanyathelo amabini.
