Gqibezela iSikhokelo kwiMicimbi yeSteel Structural: Amalungu aSekondari kunye neenkcukacha zoQhagamshelwano

Umba wangaphambili ubonise iinkcukacha kunye nemizobo yoyilo lwamalungu athwele umthwalo ophambili kunye nokuqinisa kunye nozinzo phakathi kwamalungu.isakhiwo sentsimbiamacandelo. Le seshoni iyaqhubeka nokuqaliswa kweesekondari kunye namacandelo aqhotyoshelweyo kunye nokudibanisa kunye nokufakelwa kwezakhiwo. Ngezantsi kukho iinkcazo zeendawo eziqhelekileyo zoyilo kunye noluhlu olupheleleyo lwecandelo ngalinye kwizakhiwo zentsimbi.

Amacandelo asesekondari kunye aqhotyoshelweyo abandakanya i-purlins, iintsika zesakhelo zodonga, iiplanga zesakhelo zodonga, iifreyimu zokubeka iliso, iifreyimu zecala, izitebhisi, i-stair slabs, iplatifomu, i-platform slabs, i-railings, i-handrails, i-access ladders, i-walkway plates kunye ne-spacer struts, iikholamu zocango, imiqadi yocango, iikholamu zefreyimu zefestile, iikholamu zefestile, iikholamu zefestile, iiplanga zefestile, Imiqadi yeparapet. Iipurlins zohlulwe zibe yi-purlins yophahla kunye ne-purlins eludongeni, ngelixa i-stair slabs igquma iipleyiti zokunyathela. Ukwenziwa kwemisebenzi yolwakhiwo enjengendawo ebiyelweyo, indawo yokudlula, ukukhanya kwemini kunye nokuphefumla, amacandelo alandelayo kunye ancanyathiselweyo ahambisa imithwalo yomoya, imithwalo yekhephu kunye neminye imithwalo kwisakhiwo esingundoqo. Ziyizinto eziyimfuneko eziqinisekisa ingqibelelo kunye nemisebenzi yenkonzo yezakhiwo zetsimbi.

Uqhagamshelo kunye nokufakelwa kolwakhiwo lubandakanya iipleyiti ze-gusset, iziqina, iiplate eziqinileyo, iipleyiti zeshim, iipleyiti zoqhagamshelo, iipleyiti ze-splice, iipleyiti zokugubungela, iipleyiti zokuvalwa kokuphela, iipleyiti zokuphela, iipleyiti ezisisiseko, isiseko sokuqina kwekholamu, iibholiti ze-anchor, iibholiti eziphezulu zokuqina, iibholiti zokuqina, iibholiti eziqhelekileyo, iibholiti ze-sleeve, iintsimbi eziqhelekileyo imisesane, i-diaphragms kunye ne-diaphragms enqamlezileyo. I-Stiffeners ihlulwe ibe yi-stiffeners enqamlezayo kunye ne-longitudinal stiffeners; iipleyiti ezisisiseko ziquka iipleyiti zekholam; iibholiti ze-ankile zekholamu zikwabizwa ngokuba ziibholiti zesiseko ezifakelweyo; izikhonkwane zokucheba zikwabizwa ngokuba zii-stud connectors; iidiaphragms zigquma iidiaphragm zangaphakathi kwiikholamu zebhokisi. Njengodidi olubalulekileyo lweisakhiwo sentsimbiamacandelo, uqhagamshelo kunye nokufakelwa kwesakhiwo kuqinisekisa ngokuthe ngqo ukuba onke amalungu athwele umthwalo angasebenza ngolungelelwaniso ngokufanelekileyo kwaye ingaba indlela yokudlulisa umthwalo iyaqhubeka kwaye ithembekile.

Ukuza kuthi ga ngoku, iindidi ezine eziphambili zezixhobo zentsimbi zesakhiwo ezihlelwe ngokubunjwa kwesakhiwo ziye zahlelwa. Zonke iziqendu ezingentla zidweliswe kwimidwebo yokwakha yezakhiwo zensimbi, ezifakwe kuhlalutyo lwamandla kwiingxelo zokubala zesakhiwo, kwaye zigcinwe ngokusisigxina kwizakhiwo ezigqityiweyo. Ukuhlanganiswa kwamacandelo kuyahluka kunye neentlobo zeeprojekthi ezahlukeneyo. Ukuqonda okuchanekileyo kokumiswa okusebenzayo kunye nengqiqo yoyilo lodidi ngalunye lwecandelo luyimfuneko yokuqulunqa amatyala obungakanani obuchanekileyo kunye nokumisela ngokufanelekileyo amaxabiso eyunithi abanzi, kunye nesiseko sokuqinisekisa ukuba injongo yoyilo lwezakhiwo zetsimbi inokuguqulwa ibe yizakhiwo eziphathekayo ezikhuselekileyo nezithembekileyo.
