Kuyini ukusetshenziswa kwensimbi ye-H beam?

Imishayo yensimbi ye-H, eyaziwa nangokuthi imishayo yesigaba se-H noma ikholomu yensimbi ye-h, iyisici esibalulekile sezakhiwo zensimbi kanye namaphrojekthi okwakha. Isakhiwo sensimbi ye-h beam senzelwe ukunikeza ukwesekwa okuhle kakhulu okuthwala umthwalo futhi sisetshenziswa kabanzi ezinhlotsheni ezahlukahlukene ngenxa yamandla nokuqina kwazo.
Ukusetshenziswa kweIkholomu yensimbi yesigaba se-HKubalulekile ezakhiweni zensimbi njengoba zinikeza ukwesekwa okuphezulu kwesakhiwo kanye nokuqina. Kungakhathaliseki ukuthi kuyisakhiwo sezentengiselwano, ibhuloho noma isakhiwo sezimboni, insimbi ye-H beam idlala indima ebalulekile ekuqinisekiseni ubuqotho kanye namandla esakhiwo sonke. Isimo se-H esiyingqayizivele salezi zingodo sizenza zikwazi ukumelana nemithwalo esindayo futhi zinikeze ukumelana nokugoba kanye nokugoba, okwenza zibe zilungele ukusekela izakhiwo ezinkulu kanye nemishini esindayo.
Enye yezindlela eziyinhloko zokusebenzisaUmsebe wensimbi ongu-Hisetshenziswa ekwakheni ozimele bensimbi bezakhiwo. Imishayo isetshenziselwa ukwakha uhlaka lwesakhiwo, inikeza ukwesekwa okudingekayo phansi, izindonga, kanye nophahla. Ngaphezu kwalokho, imishayo yensimbi ethengiswayo ivame ukusetshenziswa ekwakhiweni kwamabhuloho, futhi ikhono layo lokumelana nemithwalo esindayo liyenza ibe yindawo ekahle yokuhamba amabanga amade.
Ezindaweni zezimboni, i-carbon steel h beam isetshenziselwa ukusekela imishini esindayo kanye nemishini. Isakhiwo sayo esiqinile kanye nomthamo wayo wokuthwala imithwalo kwenza ifaneleke ekudaleni amapulatifomu azinzile kanye nezakhiwo zokusekela zemisebenzi yezimboni. Ngaphezu kwalokho, i-H-beams isetshenziswa ekwakhiweni kwamaphrojekthi amakhulu engqalasizinda njengezinkundla zemidlalo, izindawo zokugcina impahla, kanye nezindawo zokukhiqiza.

Uma kukhulunywa ngezindleko zomsebe wensimbi i-H, kubalulekile ukucabangela izinzuzo zesikhathi eside ezizinikezayo. Nakuba ukutshalwa kwezimali kokuqala kungaba phezulu uma kuqhathaniswa nezinye izinto, ukuqina kanye namandla ensimbi ye-H-beam kwenza kube inketho engabizi kakhulu ngokuhamba kwesikhathi. Ukumelana kwazo nokugqwala kanye nekhono lokubekezelela izimo zemvelo ezinzima kuzenza zibe ukukhetha okuthembekile nokunganakekeli kahle kwemisebenzi eyahlukahlukene yokwakha.
Kungakhathaliseki ukuthi udingaUmsebe wensimbi ongu-H ongu-30 ftnoma ugongolo lwensimbi engu-10 m H, kunezinketho ezifanela izidingo zakho ezithile. Imishayo ye-H iza ngobukhulu obuhlukahlukene kanye nokucaciswa futhi ingalungiswa ukuze ihlangabezane nezidingo zamaphrojekthi okwakha ahlukene. Ngaphezu kwalokho, izingxenye ze-H zensimbi yekhabhoni zinikeza amandla nokuqina okuhle kakhulu, okwenza kube ukukhetha kokuqala kwezicelo zesakhiwo.
Ekuphetheni, ukusetshenziswa kwe-H-beams kubalulekile embonini yokwakha, kunikeza ukwesekwa okungenakuqhathaniswa kanye nokuzinza kwezicelo eziningi ezahlukene. Insimbi enomumo we-H inesakhiwo esiqinile kanye nomthamo omkhulu wokuthwala imithwalo, okwenza kube ukukhetha okuthembekile kokwakha isakhiwo esiqinile nesihlala isikhathi eside esizohlala isikhathi eside.
