Kuyini ukusetshenziswa kwensimbi H ugongolo?

Imishayo yensimbi H, eyaziwa nangokuthi imishayo yesigaba H noma ikholomu yensimbi h, iyingxenye ebalulekile yezakhiwo zensimbi namaphrojekthi wokwakha.Isakhiwo sensimbi ye-h beam senzelwe ukuhlinzeka ngokusekelwa okuhle kakhulu komthwalo futhi sisetshenziswa kabanzi ezinhlobonhlobo zezicelo ngenxa yamandla nokuqina kwazo.
Ukusetshenziswa kweIkholomu yensimbi yesigaba Hibalulekile ezakhiweni zensimbi njengoba zinikeza ukusekelwa kwesakhiwo okuphakeme nokuzinza.Noma ngabe ibhilidi lezentengiselwano, ibhuloho noma indawo yezimboni, i-H beam metal idlala indima ebalulekile ekuqinisekiseni ubuqotho namandla esakhiwo sonke.I-H-shape eyingqayizivele yale mishayo ibenza bakwazi ukumelana nemithwalo esindayo futhi banikeze ukumelana nokugoba nokugubha, okwenza kube kuhle ukusekela izakhiwo ezinkulu kanye nemishini esindayo.
Enye yezinto ezisetshenziswa kakhuluH insimbi yensimbiisekwakhiweni kwamafreyimu ensimbi ezakhiwo.Imishayo isetshenziselwa ukwakha uhlaka lwesakhiwo, ukunikeza ukusekelwa okudingekayo kwephansi, izindonga nophahla.Ukwengeza, imishayo yensimbi engu-h edayiswayo ivame ukusetshenziswa ekwakhiweni kwebhuloho, futhi ikhono layo lokumelana nemithwalo esindayo liyenza ilungele ukuhamba amabanga amade.
Ezilungiselelweni zezimboni, i-carbon steel h beam isetshenziselwa ukusekela imishini esindayo nemishini.Isakhiwo sayo esiqinile kanye namandla okuthwala imithwalo kuyenza ifaneleke ukudala amapulatifomu azinzile kanye nezakhiwo zokusekela imisebenzi yezimboni.Ngaphezu kwalokho, imishayo ye-H isetshenziswa ekwakhiweni kwemiklamo emikhulu yengqalasizinda njengezinkundla zemidlalo, izindawo zokugcina izimpahla, nezindawo zokukhiqiza.

Uma kuziwa ezindlekweni zensimbi ye-H, kubalulekile ukucabangela izinzuzo zesikhathi eside ezinikezayo.Nakuba ukutshalwa kwezimali kokuqala kungase kube phezulu uma kuqhathaniswa nezinye izinto, ukuqina namandla ensimbi ye-H-beam kwenza kube inketho engabizi ngokuhamba kwesikhathi.Ukumelana nokugqwala kwabo kanye nekhono lokumelana nezimo zemvelo ezinzima kubenza babe ukukhetha okuthembekile nokunokunakekelwa okuphansi kwezinhlobonhlobo zamaphrojekthi wokwakha.
Ukuthi udinga aInsimbi engu-30 ft Hnoma 10 m steel H ugongolo, kukhona ongakhetha ukuze ivumelane nezidingo zakho ezithile.Imishayo ye-H iza ngobukhulu obuhlukahlukene kanye nokucaciswa kwayo futhi ingalungiswa ukuze ihlangabezane nezidingo zamaphrojekthi wokwakha ahlukene.Ukwengeza, i-carbon steel H-izigaba zinikeza amandla amahle kakhulu nokuzinza, okuzenza zibe ukukhetha kokuqala kwezinhlelo zokusebenza zesakhiwo.
Ekuphetheni, ukusetshenziswa kwe-H-imishayo kubalulekile embonini yezokwakha, ukuhlinzeka ngokusekela okungenakuqhathaniswa nokuzinza kwezinhlelo eziningi zokusebenza.Insimbi emise okwe-H inesakhiwo esiqinile namandla aphezulu okuthwala, okwenza kube ukukhetha okuthembekile ekwakheni isakhiwo esiqinile nesiqinile esizomelana novivinyo lwesikhathi.
