Masikheni ungakabi ugezele ukuthi ngisho nekheli le-H. Ithephu lesikhathi somubambo, uhluke kakhulu kunqayi. Ukusukuma kufanelela ukubala amabomu ephakeme noma izindlela ezinethunywa zokuhlanganisa amabomu angaphambili, amashawa, izindlu nokuzihlangana. Kufanelelwa ngazo izindlela ezininzi zokusukuma ngoba ithela le-H ihlale kakhulu kunye nokufanelela okungakho. Leshumo lisebenzisa ukuvumelana ngoH-ithela futhi ukuthi yini kunye nokuba kungani kufanele, ngenxa yokuba kufanele, ngenxa yokuba kufanele, ngenxa yokuba kufanele.
Ngubani ithela le-H?
I-steel yomoya: le ndawo lokugcina kulula ngokushesha njengephondo leH. Amabili amaphuphu amahhoriwe neentsha eyahlukileyo ezikhona kusetyenziswa ngokuhlala isithuthi sesiqephu ngenxa yalokho lufuneka lizihlisele ukuba libe ngamaxesha oluhlukekileyo. Ngokulandelayo, yinto engakwazi ukubuyiselwa ngabantu ababulawa ngokusebenzela i-steel yomoya nguqukukeneyo. I-steel yomoya lengenziwe ukuba zilinde umoya okupheleleyo kunye namanye amabeke ezidingekayo. Yinto elandelayo ngokushesha kwake, ngoba lokhu kungaba ngokuya kuzama ukusetshenziswa ezindaweni ezinikazana nokuba kukho imisha enkulu ekusethweni, njengemibheni wezindlela ezincinci.
Umphasho omunye wokuqinisekisa okuthiwe ngokuhluhluke kakhulu ngenxa ye-H-beam steel kunye nezinsuzwano zethu ezilondoloziwe, okanye ngaphandle kwalokho, ezintathu zeWelded uyenza amagama abangaphambili emasendvo we-energy. Imibiko yezincwadi zihlela lokhu njengoba kungaba usizo. Ukusensa kanti akuyifisa ukubhala ngokuphelele kodwa asikhubazekile. Lomthombo ufunda ukuba ungakwazi ukusebenzisa izindlela eziningi, isixa senyuka ngesikhatsi esikhulu okanye endaweni yokugcina i-quake — lokhu lihluke kakhulu ukubonisa ukusafesana kwemibuilding.
Amaphawuli asebenzayo ngo-H-shaped steel
Kuna amalawulo amadibaniswayo angapheleleyo nokuthi umhlaba wasebenzi udinga ukusebenzisa imibiko le-H-shaped steel. Amalawulo amahlelwa ngokuthi amandla amandleni kakhulu, futhi ayiqinisekiswe ngokulandelana ngezwe ngezwe.
I-Japan iyiyo yindlela elithandwayo. Ama-Japanese azithi le ndlela yiyo lwendlela yabo (JIS). Ngokwesobizo wesigaba esishapedi, I-Japan ngakho angayazi ukuthi amagama ameyinye yiyo ezinikezwe kulesigaba sishapedi ngokuba kunye nokuthi umbiko wokuqala ubekho okufanele kwi-JIS ukuze zikhuseleke izinto zakhe ezinikezwe. Ukuthi kuhlanganise ukuthi isiqephu sikwazi ukubona umthetho wakho.
IChina ise ngenxa yeso. Umbuso: i-Chinese National Standard (GB) Le ndlela iyiphumeleyo kwi-JIS, kunye nokuhlola amanani eziyisophu ngalokhu ukuthi amaqhawekazi wenkunkuma kusetyenziswa ukuba zibe ngokulandelana neziphi zezimpahla. Amabhawulethi nezingeni zazicabanga ngokukhathalelwa kakhulu kumthetho ophambili, okanye uzicabangene ngamagama amarubi abafanele.
Amathupi Akhethiwe Ekushapedini
I-H-shaped steel ingxoxwa kakhulu ngokubhekisele, kodwa kukho imigomo esisodwa ukwazi amaninzi okanye amagreydi we metal leyo lomntla. I-levels ezikhona eziyindlebe zesi-H steel zizihulumeni ngezirhawu ezidinga, ngoko ke iziqiniso nezimvume zakho zazibonakale ngaphakathi. Ngokushesha, i-H-beams eyayiphelele kakhulu kwi-building yile JIS G3101 SS400. Yile yi-grade eyayiphelele ngokuphiwa ukuba idlulisa nokuthi inceda, futhi ayikho into ekuyiphindaphinda lokusebenza kwezinye izinto.
Bamabhenkisi babekho ukukhetha ukwazi lwe-H-beam amathupi. U-Wide flange kunye no-Narrow flange bayo abangabili abangemilayo we-H-beams. Ukuthi ngaphezulu kwezinsuku, ngaphandle kokuthi kufanele ukusuka nge-joggles okanye i-crimps, u-wide flange H-beams ibezise kuwo edges ngaphezulu kunye nokuthi bazifaka umlando wokuhlala ngaphezulu phakathi kwabantfu elishumi ngokuphambili kwe-narrow flange beams. Kuningi lamabhenkisi ukwazi ukuphila kwe-ibeam amathupi lokuzama ukukhetha amaxesha emasunguliweni.
Amahamsi ameH ayishintshwa ngemibuzo ezidingekileyo kunye negcino, okungakwazi ukuba zikhokhe umoya wabo ongavunyelwe. Ababhedlela babizwa ukulula ukukhetha i-H-beam esingisekelwe yindlela yakho yokusebenzela icamber.
Ukusebenza uH-Shaped Steel Ngokubhebhu
Ukusebenza uH-shaped steel usetyenziswa ukuthi kufanele ukwazi ukuba kusetshenziswa futhi imithetho yayo. Okungaba kuhle ukwazi ukuphindephindvwa kokudibanisa kweH-shaped steel kunye nokugcinwa kwake. Ukuthi le nformayini lihlaleke, ababhedlela bazokwenza izinhlobo zakhe zasendaweni ngokubhebhu kunye nokuhlala ngempumelelo.
I-H shaped steel ingakushintsha abantu bakwenze izinhlobo zokubhedlela ezihluke kakhulu ngokuphi ndawonye. Lokunye lokungakwazi ukuba umthengisi wesiti we-H uhlu lomkhankaso, lokuthi kulowera isiphathimende sokubhekana noma izifiso eziphumaphuma emva kwalokunye. Kungcono sifanele sibizwe ukuthi wonke umntu osebenzisa amagama angasebenzela kanye nokusebenzela imithombo.
Ngokwesobizo, futhi umuntu ophambili wabantu ababekhona kwisezilungiselelo zokulandelana kufanele alithi ngubani ngoH-shaped steel. Ukulungisa i-H-shaped steel, amastandawrd eziningi nayo nokusetyenziswa kuyahlala kuhlukele isimo seshuleyo ukuvumela ukuba isimo sikuhlukwe ngempumelelo. Thina eEhongsteel siyavumela ukuthi sihlale kwakhona ngesiphumo esikhize kakhulu le-H-shaped steel futhi sibonisa lapho amanani angama-databases akhona kusezilungiselelo.
