Ukuguqulwa kwecandelo
1. Icandelo likhubazekile ngexesha lokuthutha, okubangelwa ukugoba okufileyo okanye okuthambileyo, okwenza ukuba icandelo lingakwazi ukufakwa.
Uhlalutyo lwesizathu:
a) Uguqulo oluveliswayo xa amalungu enziwe, aboniswa ngokubanzi njengokugoba okucothayo.
b) Xa icandelo liza kuthuthwa, indawo yokuxhasa ayifanelekanga, njengenkuni ye-cushion ephezulu kunye nesezantsi ayimi nkqo, okanye i-stacking site subsidence, ukwenzela ukuba ilungu liya kuba nokugoba okufileyo okanye ukuguqulwa okucothayo.
c) Izixhobo zikhubazekile ngenxa yongquzulwano ngexesha lothutho, ngokuqhelekileyo zibonisa igophe elifileyo.
Amanyathelo othintelo:
a) Ngexesha lokwenziwa kwamacandelo, amanyathelo okunciphisa i-deformation iya kwamkelwa.
b) Kwindibano, amanyathelo afana ne-reverse deformation kufuneka yamkelwe.Ukulandelelana kwendibano kufuneka kulandele ulandelelwano, kwaye izixhaso ezaneleyo kufuneka zimiselwe ukuthintela ukuguqulwa.
c) Kwinkqubo yothutho nothutho, nikela ingqalelo kubume obufanelekileyo beepads.
Izisombululo:
a) Ukugoba okufileyo kwelungu kunyangwa ngokulungiswa ngoomatshini.Sebenzisa iijack okanye ezinye izixhobo zokulungisa okanye nge-oksijini yomlilo we-acetylene emva kokulungiswa kokubhaka.
b) Xa ulwakhiwo lugoba ngobunono deformation, thatha oxyacetylene idangatye ukulungiswa ubushushu.
2. Emva kokudibanisa amalungu entsimbi yentsimbi, ubude obugcweleyo bugqithise ixabiso elivumelekileyo, okubangelwa umgangatho ophantsi wofakelo lwentsimbi.
Uhlalutyo lwesizathu:
a) Inkqubo yokuthunga ayinangqiqo.
b) Ubungakanani beendawo ezidibeneyo azihambelani neemfuno zoyilo.
Izisombululo:
a) Amacandelo eNdibano yokuseta itafile yendibano, njengewelding ukuya emazantsi omgangatho welungu, ukuthintela ukungquzulana.Ukudibanisa itafile kufuneka ibe kwinqanaba ngalinye le-fulcrum, i-welding ukukhusela ukuguqulwa.Ngokukodwa kwindibano ye-boam okanye ileli, kuyimfuneko ukulungelelanisa i-deformation emva kokubeka i-welding, kwaye ubeke ingqalelo kubungakanani be-node ukuhambelana noyilo, ngaphandle koko kulula ukubangela ukuphazamiseka kwecandelo.
b) Ilungu elinobungqongqo obungalunganga kufuneka liqiniswe phambi kokuba lijike kwaye lidibanise, kwaye ilungu kufuneka lilinganiswe emva kokuphethuka, kungenjalo ilungu alinakulungiswa emva kwe-welding.
3. Amacandelo arch, ixabiso elomileyo elikhulu okanye elingaphantsi kwexabiso loyilo.Xa ixabiso le-arch lecandelo lincinci, i-beam igobile emva kokufakwa;Xa ixabiso le-arch likhulu, ukuphakama komphezulu we-extrusion kulula ukudlula umgangatho.
Uhlalutyo lwesizathu:
a) Ubungakanani becandelo abuhambelani neemfuno zoyilo.
b) Kwinkqubo yokwakhiwa, amaxabiso alinganisiweyo kwaye abalwayo awasetyenziswa
