Sawubona! Futhi ngaleso sikhathi isihloko esizozithutha ngaso yisahluko se-I-line. Manje ungahle uchazeke, kungani ke i-H-Beams? I-H-beam yisahluko esiphambili esibekwe ngokujwayelekile njengendawo ekuqaleni yezinkulungwane zokwakha ezayisebenziswa manje phakade. Kanti, lezi zinconyane ekuphileni ngoba manje unazo izindlela ozodinga ukuyikhipha. Lokhu kwenza kube lula ukusebenzisa emakhishini okwakha. Qaphela, akukho H-beam onjalo. Akune lokho onke kusebenza emphahleni. Ngaleso sikhathi sizothetha ngendlela ongayibala ngayo ukuthi i-H-beam yakho iyathembeka.
Ukuchazi Kweqiniso Elifanayo
Izimpendulo ezibalulekileyo kungumthetho omkhulu kakhulu (ukulawula ubungako beprofayela H nobuntombi babo) => Umthetho omkhulu kakhulu we-H- isihlahla SeCarbon izibhamu ziqukatha ngamathuba amaningi ukuqwaluka kwabo, ukuthi kufanele kube yini ifomu yazo, nokuthi lo mfundo waphi ofakelwa. carbon steel sheet uma izibhamu ze-H zifuneka zisebenziswe emsheneshweni: kumele ziqhathanise ngokuphelele ngezi zimpendulo, khona-ke kunehlungwini lokushisa. Kodwa, uma zama ukulahlekelwa lezimpendulo kungaba nomthelela omkhulu ngoba phakathi kwe pPGI ubuchwepheshe bezibhamu akuzange benze okuthinta kuye. Ngakho ke kumele sibophelele lezinto eziphathelene ngempela.
Izilinganiso Ezibalulekile
Kodwa, ngokwesithuthi se-H-beam, kumele sikhangele izikhathala ezithile ukuze siyiqhobeke njengalungileyo. Kungakanjani okuphezulu kusithuthi ukusuka kuqiniswe, phansi, nokumelene nomunye umunwe? Futhi, ngokubona, kumele sibone ubukhulu beflange, kepha amaqoshiso amancane ephezulu noma phansi yesithuthi se-H-beam, futhi sibone ubukhulu be-web engaqeda umunye umunwe kwenye. Kumele sifakelane lezi zimbini izikhathala ukuze isithuthi se-H sihlale salunge. Uma one of these two dimensions ayikhangelwanga ngempela, isithuthi se-H singaba nesimo esihlatshwayo. Kunezixhobo ezakhiwe ngokuthaka ukuze kikhangelwe ngempela, lokhu kuyilokho okubalulekile ukuqinisekisa ukusetshenziswa kwempela kalesi siqalekiso. Ukuqinisekisa ububi, izithuthi ze-H kumele zijonge izinyathelo ezilandelayo kufanele zenzeke kakuhle ukuqinisekisa ukuthi izithuthi ze-H zilungile. Okokuqala, sijonga ubunzima bwezinto eziphathelene nesitsha esifanele ukusetshenziswa; umlilo akumele uphulwe. Ukwenza kwesithuthi se-H kwenziwa ngokukhangeleka, izikali nezimpendulo kumele zichekwe ukuze kuhlale kuchazwe ukuze kugcinwe kabusha ngaphambi kokuba kugcwaliseke. Emva kokugcwalisa isithuthi se-H, k
