Uyini umehluko phakathi kwe-C-beam ne-U-Beam?

Okokuqala nje,U-beamiwuhlobo lwensimbi okuma kwayo okuphambene kufana nohlamvu lwesiNgisi oluthi “U”. Ibonakala ngengcindezi ephezulu, ngakho-ke ivamise ukusetshenziswa kubakaki bephrofayela yemoto i-purlin nezinye izikhathi ezidinga ukumelana nengcindezi enkulu.

Emkhakheni wezokwakha nobunjiniyela,Insimbi U Beamnazo zivame ukusetshenziswa njengama-purlins, izakhiwo zokusekela, njll. Ziyakwazi ukumelana namandla ahlukahlukene, njengokucindezela. Bangakwazi ukumelana namandla ahlukahlukene, njengokucindezela, ukugoba nokugunda, futhi babe nokusebenza okuhle kwesakhiwo namandla okuthwala umthwalo. Ngaphezu kwalokho, ama-U-beams angahlanganiswa ngokukhululekile ukuze enze izinhlobo ezihlukahlukene zezingxenye zokwakha, njengamafreyimu ophahleni namabakaki.

Ngokombono wenqubo yokukhiqiza,C uhlakakanye nensimbi yesiteshi yendabuko uma kuqhathaniswa namandla afanayo e-C-beam ingasindisa u-30% wezinto ezibonakalayo, lokhu kuyinzuzo enkulu ye-C-beam, isizathu siwukuthi i-C-beam icutshungulwa ipuleti eligoqiwe elishisayo eligobayo elibandayo futhi libe yinto encane enezindonga futhi engasindi, ukusebenza kwesigaba esiphambene kanye nokuphakama kwayo, futhi amandla aphezulu kakhulu.

 

Ngaphezu kwalokho, siyazi ukuthi insimbi ye-u beam ingukukhiqizwa okugoqelwe ukushisa, ukushuba kukhulu kakhulu, kodwa isiteshi se-C siwukukhiqiza umugqa wensimbi obandayo (nakuba kukhona ukukhiqizwa okushisa okushisayo), ukushuba kuncane kakhulu uma kuqhathaniswa nensimbi yesiteshi, kodwa futhi kusukela ekubukeni kokuhlukaniswa kwabo, kukhona umehluko omkhulu. Okujwayelekile phansi ukubona insimbi yesiteshi ingahlukaniswa: insimbi evamile yesiteshi kanye nensimbi yesiteshi engasindi. Ukucaciswa kwensimbi evamile egoqelwe eshisayo ingu-5-40#. Ukucaciswa kwensimbi eguquguqukayo egoqiwe eshisayo enikezwe isivumelwano phakathi kwezinhlangothi zokuhlinzeka nezidingo ngu-6.5-30#. Ngokwesimo sensimbi yesiteshi ingahlukaniswa ngezinhlobo ezi-4: insimbi yeshaneli ebandayo eyakhiwe ngendlela elinganayo, insimbi engalingani emaphethelweni abandayo eyakhiwe, insimbi yeshaneli egoqiwe eyakhiwe ebandayo yangaphakathi, insimbi yamashaneli abandayo eyakhiwe ngaphandle. Kodwa insimbi yesiteshi i-C ihlukaniswe ngokuthi: i-galvanized C channel, i-hot-dip galvanized cable tray C, i-glass curtain wall channel C, i-Channel C engalingani, i-C steel rolled edge, uphahla (udonga) insimbi ye-purlin C, amaphrofayili ezimoto C insimbi nokunye. Ngale ndlela, kubonakala sengathi umehluko phakathi kwe-C-channel ne-u beam uyabonakala futhi ngokombono wokuhlukaniswa ngezigaba kuphela.

Okokugcina, indlela elula yokuhlukanisa phakathi kwe-u beam kanye ne-c channel yisimo sabo se-cross-section, i-C Channel Steel yigama eligcwele lensimbi egoqwe yangaphakathi eyakhiwe ngamakhaza, lapho singakwazi khona ukuthi i-C-channel cross-section iwunqenqema olugoqiwe, kuyilapho i-u beam steel iwunqenqema oluqondile.
