Amanothi ekwakheni kwe-coupler-Type Steel Pipe Scaffoldings

1 Ukusuka engxenyeni yokusebenza phansi, ungqimba lwamapulangwe athukiwe kufanele kubekwe njalo nge-12m.

2. Ngaphandle kwesinyathelo esiphezulu esitezi esiphezulu, amalunga wesinyathelo ngasinye kwezinye izitezi kufanele axhunywe ngabakwa-Butt Fasterers lapho belula i-pole. Amalunga ezigxobo ezimbili eziseduze angeke abekwe ngaphakathi kwesinyathelo esifanayo. Ibanga eligxilile ekuqondisweni okuphakeme kwamalunga amabili ahlukaniswe yisigxobo esisodwa mpo ngaphakathi kokuvumelanisa akufanele kube ngaphansi kwama-500mm: ibanga ukusuka enkabeni yokujoyina ngakunye akufanele libe likhulu kunebanga lesinyathelo kungafanele libe libanga lesinyathelo. 1/3. Uma isigxobo esingemuva esiphezulu sinwetshwa ngokugqashuka, ubude be-overlap akufanele bube ngaphansi kwe-1000mm futhi kufanele bulungiswe ngokungaphansi kwama-fasteners ezi-2. Ibanga ukusuka emaphethelweni wepuleti yesembozo se-falleter yokugcina esiphethweni sePole akufanele kube ngaphansi kwe-10mm.

I-3. I-transververver evundlile kufanele ifakwe kwi-node enkulu, eboshwe ngama-fasteners alungile, futhi ukususwa akuvunyelwe ngokuphelele. Ibanga eliphakathi phakathi kwama-fasteners amabili angesokudla endaweni enkulu akufanele abe likhulu kune-150mm. Ku-Double-Row Scaffolding, ubude besengezo benduku evundlile evundlile ekugcineni kodonga akufanele lube lukhulu kune-500mm.

I-4. I-scaffolding kumele ifakwe izigxobo eziqonde mpo nasezivundlile. Izigxobo eziqonde mpo nezivundlile kufanele zilungiswe ezigxotsheni ezimile kude kungabi ngaphezu kwe-200mm kusuka ku-epithelium eyisisekelo usebenzisa ama-fasteners alungile. Lapho isisekelo sesigxobo mpo asikho endizeni efanayo evundlile, isigxobo esithe mpo endaweni ephakeme kufanele sinwetshwe ngezikhala ezimbili endaweni ephansi futhi zilungiswe esigxotsheni esithe mpo. Umehluko wokuphakama akufanele ube mkhulu kune-1m. Ibanga ukusuka e-axis yesigxobo ngaphezulu komthambeka kuya emthambekeni akufanele kube ngaphansi kwama-500mm.

I-5 Okokulila okukodwa futhi okuphindwe kabili kuphakama okuphezulu okungaphansi kwama-24m, izingxenye ezixhumeke ngodonga eziqinile kufanele zisetshenziselwe ukuxhuma ngokuthembekile esakhiweni, noma ukuxhumana okunamathiselwe odongeni usebenzisa imigoqo ye-tie kanye nezisekeli eziphezulu nazo zingasetshenziswa. Kuvinjelwe ngokuphelele ukusebenzisa izingxenye zodonga oluguqukayo ngemigoqo ye-tie kuphela.

I-6. Zombili iziphetho zomugqa wensimbi onomugqa onomugqa oqondile futhi ovulelekile wensimbi Ukuvalwa okuvaliwe ngokuphakama okuphezulu ngenhla kwama-24m, ngaphezu kwe-diagonal braces eguqukayo okufanele kusethwe emakhoneni, umuntu kufanele ahlelwe njalo ngezikhala ezi-6 phakathi. Ama-transverver diagonal brace kufanele ahlelwe ngokuqhubekayo kuphethini le-zigzag kusuka phansi kuya phezulu phakathi kwezigaba ezifanayo.
