Umgangatho waseMelikaNdiyaqaqambayintsimbi esetyenziswa ngokuqhelekileyo yokwakha, iibhulorho, ukwenziwa koomatshini kunye nezinye iinkalo.
Ukukhetha inkcazo
Ngokwemeko ethile yokusetyenziswa kunye neemfuno zoyilo, khetha imilinganiselo efanelekileyo. Umgangatho waseMelikaIntsimbi ndiyayibethazifumaneka kwiinkcukacha ezahlukeneyo, ezifana ne-W4×13, W6×15, W8×18, njl njl.
Ukukhetha izinto eziphathekayo
Imiqadi ye-American Standard I-I-beams idla ngokuba yenziwe ngentsimbi eqhelekileyo ye-carbon structural. Xa ukhetha, nikela ingqalelo kumgangatho kunye namandla ezinto eziphathekayo kunye nezinye izikhombisi zokuqinisekisa ukuba ihlangabezana neemfuno zokusetyenziswa.
Unyango lomphezulu
Umphezulu we-American Standard I-beam unokunyangwa nge-galvanizing yediphu eshushu kunye nokupeyinta ukuphucula ukuxhathisa ukubola. Xa ukhetha, unokuqwalasela ukuba ngaba unyango oluphezulu luyafuneka ngokwemiqathango ethile yokusingqongileyo.
Ukukhetha umthengisi
Khetha abanikezeli abasemthethweni nabahloniphekileyo ukuba bathenge i-American Standard I-beams ukuqinisekisa umgangatho wemveliso kunye nenkonzo emva kokuthengisa. Ungabhekisa kuvavanyo lwemarike, isiqinisekiso somthengisi kunye nolunye ulwazi lokukhethwa.
Ukuhlolwa koMgangatho
Ngaphambi kokuthenga, unokucela umthengisi ukuba anikeze isatifikethi somgangatho kunye nengxelo yovavanyo yemveliso ukuqinisekisa ukuba i-American Standard I-beam ethengiweyo ihlangabezana nemigangatho efanelekileyo kunye neemfuno.
Ukuqinisekisa ukuba i-i-beam ethengiweyo ihlangabezana neemfuno zoMgangatho waseMelika, unokuthatha ezi ndlela zilandelayo:
Jonga imigangatho efanelekileyo yase-US
Qonda imigangatho efanelekileyo yase-US, efana nemigangatho ye-ASTM (i-American Society for Testing and Materials), ukuqonda iimfuno zokucaciswa kunye neemfuno zokusebenza kwe-i beams.
Khetha ababoneleli abafanelekileyo
Khetha ababoneleli abanegama elihle kunye nesiqinisekiso sobuchule sokuqinisekisa ukuba i-beam eveliswe ngabo ihlangabezana neemfuno zoMgangatho waseMelika.
Ukubonelela ngezatifikethi kunye neengxelo zovavanyo
Funa ababoneleli ukuba babonelele ngezatifikethi ezisemgangathweni kunye neengxelo zovavanyo lwemathiriyeli ezihambelanayointsimbi i imiqadiukuqinisekisa ukuthobela kwabo iimfuno ze-AFSL.
Yenza uvavanyo lwesampula
Unokukhetha ukwenza isampula yeminye imiqadi ethengiweyo kwaye uqinisekise ukuba iipropati zabo eziphathekayo kunye nokwakheka kweekhemikhali zithobela iimfuno ze-AFSL ngovavanyo lwebhubhoratri kunye nokuhlolwa.
Funa uncedo kumbutho wovavanyo lomntu wesithathu
Umbutho wesithathu ozimeleyo wokuvavanya unokuthunyelwa ukuba uvavanye kwaye uvavanye i-i-beams ezithengiweyo zokuqinisekisa ukuthotyelwa kwazo kwiimfuno ze-AFSL.
Jonga kuphononongo lwabanye abasebenzisi kunye namava
Ungabhekisa kuvavanyo lwabanye abasebenzisi kunye namava ukuze uqonde izimvo zabo malunga nababoneleli kunye nomgangatho wemveliso ukwenza isigqibo sokuthenga esinolwazi ngakumbi.
