Yakagadzirirwa square machubhu emhando dzakasiyana siyana
1. Kutsauka kunobvumirwa kwemadziro emukobvu wepombi yeskweya hakupfuurire kana kubvisa 10% yezita remadziro ukobvu kana ukobvu hwemadziro husina kukura kupfuura 10mm, uye kuwedzera kana kubvisa 8% yehukobvu hwemadziro apo ukobvu hwemadziro hwakakura kupfuura. 10mm, kunze kwekukobvu kwemadziro ekona uye weld nzvimbo.
2.Iyo yakajairika yekutakura kureba yeskweya rectangular pombi ndeye 4000mm-12000mm, kazhinji 6000mm uye 12000mm. Iyo rectangular chubhu inotenderwa kuendesa zvipfupi uye zvisina kuisirwa kureba zvigadzirwa zvisingasviki 2000mm, kana muchimiro chechubhu yekubatanidza, asi Demander ichacheka interface chubhu kana ichiishandisa. Huremu hwehurefu hupfupi uye husina kusimba zvigadzirwa hazvipfuure 5% yehuwandu hwekuburitsa vhoriyamu, uye kune masikweya nguva machubhu ane huremu hwekufungidzira hwakakura kupfuura 20kg / m, haifanire kudarika 10% yehuwandu hwekutakura.
3. Iyo yekukombama degree yeskweya rectangular pombi haizove yakakura kupfuura 2mm pamamita, uye iyo yakazara yekukotama dhigirii haizove yakakura kupfuura 0.2% yehurefu hwakazara.
Nzvimbo dzekushandisa dzesquare chubhu: inoshandiswa zvakanyanya mukugadzira michina, indasitiri yekuvaka, indasitiri yesimbi, mota dzekurima, dzimba dzekurima dzekurima, indasitiri yemotokari, njanji, migwagwa mikuru yekuchengetedza, skeleton yemidziyo, fenicha, kushongedzwa uye chimiro chesimbi.
For engineering kuvaka, girazi keteni rusvingo, musuwo uye hwindo kushongedzwa, simbi chimiro, guardrail, muchina kugadzira, motokari kugadzira, imba mudziyo kugadzirwa, shipbuilding, mudziyo kugadzira, magetsi emagetsi, zvokurima kuvaka, zvokurima greenhouse, bhasikoro furemu, mudhudhudhu furemu, pasherufu, midziyo yekusimbisa muviri, nhandaro uye zvigadzirwa zvekushanya, fenicha yesimbi, zvakasiyana-siyana zveoiri casing, pombi yemafuta uye pombi pombi, mvura, gasi, tsvina Mhepo, kudziyisa uye kumwe kufambiswa kwemvura, kurwisa moto uye rutsigiro, indasitiri yekuvaka, nezvimwe.
