Iingcebiso zokukhetha ze-American Standard I-beam kunye nentshayelelo

Umgangatho waseMelikaNdiyakhazimlayintsimbi 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, qwalasela umgangatho 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 ngokweemeko ezithile zokusingqongileyo.

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 zihambelana neemfuno 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 kuvavanyo lwabanye abasebenzisi kunye namava

Ungabhekisa kuvavanyo lwabanye abasebenzisi kunye namava ukuze uqonde izimvo zabo malunga nababoneleli kunye nomgangatho wemveliso ukwenza isigqibo sokuthenga esinolwazi ngakumbi.
