Isiteshi Steel - omunye lwezinhlobo ezivame kakhulu metal

Noma yimuphi ukwakhiwa (ezimbonini noma civil) kuqedile ngaphandle kokuba ukusebenzisa inani elikhulu hardware ezahlukene (metal izimpahla) ukuthi singasetshenziswa amadivayisi yasibamba, futhi njengengxenye kwesakhiwo zelungu. Ezimweni eziningi isimbembembe zenziwa yemihlobo ehlukeneko steel (carbon okungcono ongaphakeme), kanti ethandwa kakhulu phakathi kwabo kukhona imikhiqizo metal, ikakhulukazi amaphrofayli ukwakhiwa. Ngokwakha amaphrofayli zihlanganisa imikhiqizo efana imishayo, izinhlobo, mina-imishayo, iziteshi, engeli, njll

Lesi sihloko sigxile kakhulu iziteshi, ezisetshenziswa emikhakheni eyehlukene kokubili ukwakhiwa ezimbonini kanye civil.

Umqondo U-izigaba

Iziteshi Beam (isiteshi steel) ibizwa ngokuthi ugongolo elinendawo ezimise U-kwesigaba esiphambanweni; isigaba okunjalo kwezinkolo kubizwa ngokuthi "ibhokisi-like". Ezimweni eziningi iziteshi ezisetshenziswa njengeziwusizo isici esinikeza izinga esingeziwe ukuzinza futhi azidlulisele rigidity. Liphinde lunikeze ukumelana enhle kakhulu imithwalo Axial nokugotshiswa.

Yini eyenza?

Ngokuqondene yokukhiqiza impahla, ngokuvamile wasebenzisa izinhlobo ezihlukahlukene zezinhlamvu steel (steel kwesakhiwo nge alloying izithasiselo, ongaphakeme kanye eliphezulu carbon), kuncike nezidingo isakhiwo. Ngakho, eqinisweni, igama - the "isiteshi ensimbi." Kwezinye izimo, ezifana e wokwakha imoto, nemigoqo, kukhona izidingo ezikhethekile: Kumele ube izakhiwo anti-ezonakalisayo bona. Ngenxa yalezi zinjongo, wenza iziteshi steel ekhethekile insimbi, izindleko okuzoba ephakeme, kodwa engaqhathaniswa izici Thermo-ngokomzimba, zingabantu okuhlala isikhathi eside ngokungadingekile emathonyeni zangaphandle, ziqhathaniswa ashisayo isiteshi ibha.

ngezigaba

Isiteshi steel njengoba imikhiqizo metal iphuma kungenziwa labizwa ngokuthi elandelayo:

1. Kuye senqubo yokukhiqiza:

• Iziteshi Zezıhlabane iphuma steel (oluqanjwe ugingqe ashisayo);
• ekhethekile;
• equilateral Lwalugobile (oluqanjwe goba abandayo emshinini ekhethekile obumba);
• ukungalingani Lwalugobile (oluqanjwe ubuchwepheshe obufanayo njengoba ifomu odlule).

Phela, kufanele kuphawulwe ukuthi steel isiteshi ashisayo iphuma izimisele nibonakala ezahlukene: the yokugcina okukhethwa kukho lapho ubuso babanjwa, okungukuthi, umkhiqizo ayinakho emakhoneni ebukhali, kuyilapho ama-hot sill kukhona njalo emagumbini (bheka isithombe ngezansi.).

Iziteshi ashisayo iphuma

iziteshi lwalugobile

2. Kuye ukuma nosayizi:

• Thina - lolu hlobo has imiphetho engaphakathi emashalofini nge ukuchema kuzo ezithile;
• P - emashalofini umkhiqizo ngobuso parallel;
• E - imodeli ukonga nge imiphetho okucishe kufane nalokhu Shelving;
• L - ukukhanya uchungechunge onobuhle ngobuso parallel;
• C - umkhiqizo uchungechunge ezikhethekile.

3. Ngokusekelwe ukunemba ukusebenza iphuma, iziteshi ungaba:

• A - ekilasini (ngokunemba high ekilasini);
• B - ekilasini (ukunemba ngaphezulu);
• B - ekilasini (class esisodwa ngokunemba).
