High-simba simbiinogona kushandiswa muzvigadzirwa zvesimbi kuchengetedza huwandu hwesimbi inoshandiswa uye kuderedza mari yekugadzirwa kwesimbi, kutakura uye kuisa.Sezvo michina yesimbi yakasimba-yakasimba misiyano isingaiti nesimbi yakajairika, nyanzvi dzekumba nekune dzimwe nyika dzakaita basa rakawanda rekutsvagisa pamusoro pekushandiswa kwesimbi yakasimba-yakasimba mumakore achangopfuura.

Mukuwedzera kune inonzwisisika nhengo yekugadzira, yakakwirira-yakasimba simbi zvivako zvinoda hukama hwakanaka pakati penhengo dzesimbi dzakasimba kuti dzigadzire chimiro chakachengeteka uye chakavimbika.

Kufambira mberi kwekutsvagisa kwemaitiro maviri akakosha ekubatanidza simbi yakasimba-yakasimba (welding uye bolting) kumba nekune dzimwe nyika inounzwa, kusanganisira: tsvakiridzo pamusoro pekuita kwekutakura-kuremerwa kwesimba resimbi butt-weld connection, tsvakurudzo pamusoro pekutakura-kutakura. kushanda kwepamusoro-simba resimbi fillet-weld yekubatanidza, kutsvagisa pamusoro pekuita-kuremerwa kwekuita kwesimbi-yakasimba friction-type bolting, tsvakiridzo pamusoro pekutakura-kuremerwa kwekuita kwesimbi-yakasimba yekutsikirira-mhando yekutsikirira uye tsvagiridzo pahydrogen- kunonoka kutyoka kwemabhaudhi akasimba egiredhi 12.9, zvichingodaro, uye inoratidza kufambira mberi kwekutsvagisa kweTongji University.Tongji University, inopfupikisa kufambira mberi kwetsvakiridzo iripo uye kutarisa kumberi kune ramangwana rekutsvaga.

Kushandiswa kwepasi-simba matching mubutt welding ye-high-simba simbi inogona kuderedza kupisa kwekushisa kwekushisa, kuderedza kukanganisa kwehuputi uye kugadzirisa ductility yejoint.

Nekudaro, pasi-kusimba kuenzanisa kunogona kuve nemhedzisiro yakakosha pakuremedza-kuremerwa kugona kweiyo welded joint.Vazhinji vaongorori vakaratidza kuti mhedzisiro yeEuropean kodhi EC3 pane yepasi-simba kuenzanisa yewelded majoini masimba ekuverenga zvigadziro zvine musoro kana kuchengetedza.

Yakakwirira-simba resimbi inonyorovesa chiitiko mushure mekugadzira uye saizi yedhigirii yekunyorovesa uye simbi yekusimbisa michina, kukunguruka muitiro uye kunzwa kwekupisa kurapwa, nekuda kwesimbi-yakasimba simbi mukukunguruka kwave imwe kana kupfuura kupisa kurapwa, iyo simbi iri pedyo. iyo weld uye yekupisa yekuisa uye kutonhora kutenderera kutenderera kwekugadzirisa, kuitira kuti isakwanise kuchengetedza iyo yepakutanga mechanical properties, uye naizvozvo kupisa-kukanganisa nzvimbo.

Zvimwe zvinhu zvinokanganisa kusimba kweiyo welded joint zvinosanganisira kusimba kweiyo weld material, hupamhi hweweld zone, kupfavisa zone simba, kupfavisa zone hupamhi, hupamhi-ukobvu reshiyo yechikamu chakasungwa uye weld bevel angle.

1) nzira dzakasiyana dzekutora slip load dzine simba guru pane-anti-slip coefficient, uye kukosha kwe-anti-slip coefficient yeChinese code ndeye 7% kusvika ku20% yakakura kudarika kukosha kweEuropean code.

2) Pamhepo inoputika, iyo yakayerwa kukosha kweiyo-anti-slip coefficient yesimbi yakasimba-yakasimba iri pakati pe0.45 ne0.50 maererano neEuropean code, uye kana imwe chiyero chekuchengetedza chengetedzo ichitariswa, kukosha kwedhizaini kunoenderana. 0.4 uye 0.45.

3) THe anti-slip coefficient of red rust surface mushure mepfuti kuputika kwesimbi yakasimba-yakakwirira kunowanzova kukuru kudarika iyo yepfuti inoputika.

4) Tiye anti-slip coefficient yehigh tensileswaya refubhurashi pamusoro pezvimiro zveEuropean iri padyo neukoshi hunotorwa zvinoenderana netsika dzeChinese, iyo anti-slip coefficient inodzikira nekuwedzera kwesimbi giredhi resimba.

5) Iko kurapwa kwepamusoro kwesimbi-yakasimba simbi yakapfurwa uye yakaputirwa ne-inorganic zinc-rich pendi inogona kuwedzera kugadzikana kwe-anti-slip coefficient yeiyo friction surface, uye mwero we-anti-slip coefficient kazhinji idiki pane imwe nzvimbo. nzira dzokurapa.Ukobvu hweiyo inorganic zinc-rich pendi coating inobatsira pakuvandudzwa kweiyo slip resistance coefficient, uye slip resistance coefficient of the thick coating ingangoita 10% yakakwirira kudarika iyo yeatete coating.
