Umqadi we-H, eyaziwa ngokuba ziikholamu ze-universal okanye ii-I-beams, zizinto ezisisiseko zesakhiwo kulwakhiwo lwanamhlanje kunye nobunjineli. Icandelo labo elinqamlezileyo lifana nonobumba u-'H' okanye u-'I'. Le milo ikhethekileyo inika umlinganiselo okhethekileyo wamandla-kubunzima, nto leyo eyenza ukuba zingabi yimfuneko ekuthwaleni imithwalo enzima.
Esi sikhokelo sibanzi siza kuhlola ihlabathi leemitha ze-H zaseYurophu eziqhelekileyo. Siza kujonga iinkcukacha, usetyenziso, kunye nomahluko ophambili kwiiprofayili eziphambili: amacandelo e-HEA, HEB, kunye ne-HEM.
Zithini ii-H Beams?
Abavelisi baqengqa imiqadi ye-H ibe ngamalungu esinyithi anecandelo elinqamlezileyo elifana nonobumba u-“H.” Ziqulathe ezimbini ezihambelanayoiiflangeiqhagamshelwe ngokuthe nkqoiwebhuOlu yilo lusasaza umthwalo ngokufanelekileyo kwaye lumelana namandla agobekayo kwiindlela ezahlukeneyo. Inkqubo yokujika-jika ishushu iyenziwaIntsimbi yeCarbonUmqadi we-H, evelisa iiprofayili ezihambelanayo ezineempawu ezibalaseleyo zoomatshini.
Iingenelo eziphambili zezakhiwo ze-H Beam
Umthamo oPhezulu wokuthwala umthwalo:Uhlobo lwe-H lusasaza intsimbi ngokufanelekileyo, lubeka uninzi lwezinto kude nombindi wayo. Oku kwandisa amandla abalulekileyo (umzuzu wokungakhathali kunye ne-section modulus), okwenza ukuba ikwazi ukuxhasa imithwalo enzima.
Ukuguquguquka:Ifanelekile kwiikholamu, imiqadi, iipurlin, kunye nezakhiwo ezahlukeneyo ezidityanisiweyo.
Ukusebenza kakuhle kweendleko:Ukusetyenziswa kwezinto ezincinci ukuze kubekho amandla afikelelekayo kukhokelela kuyilo lwezoqoqosho
Ubulula bokwenza:Kulula ukuwelda, ukubopha, kunye nokulungisa ngokweemfuno ezithile zeprojekthi.
Ukuthembeka Okuqinisekisiweyo:Ubukhulu obumiselweyo kunye nokusebenza okuqikelelweyo phantsi koxinzelelo
Ukuntywila nzulu: Iibhanti ze-H ezisemgangathweni zaseYurophu – HEA, HEB, HEM
Imiqadi ye-H esemgangathweni yaseYurophu ihlulwe ngokuyintloko ngokwemilinganiselo yayo kunye nobunzima bayo ngemitha nganye. Uthotho oluqhelekileyo lolu:
Iimitha ze-HEA (Uthotho lokukhanya)
Imisebe ye-HEA ibonakaliswa ngokulinganiselaiiflange ezincinci nezincincixa kuthelekiswa nobude bazo. Zidla ngokubizwa ngokuba “zii-light series” okanye “zii-IPE-like” light h-beams kodwa zine-flanges ezibanzi.
Izicelo eziqhelekileyo:Izinto zesakhiwo sesibini, ii-purlins, iikholamu ezikhaphukhaphu, kunye nokusetyenziswa apho kulindeleke imithwalo ephakathi.
Uphawu oluPhambili:Ixabiso liphantsi xa kuthelekiswa nobude obunikiweyo, nto leyo evumela ukugoba okujikeleze i-major axis.
Ii-HEB Beams (Uthotho oluPhakathi/oluQhelekileyo)
imiqadi ye-HEB imeleuthotho oluqhelekileyo okanye oluphakathi-ububanzi obuphakathi be-h, equkaiiflange ezibanzi nezityebileyokuneenxalenye ze-HEA ezinobude obufanayo.
Izicelo eziqhelekileyo:Iikholamu eziphambili ezithwala umthwalo kunye neebhanti kwizakhiwo, kwizakhelo zoshishino, nakwiibhulorho. Olu lolona luhlu lusetyenziswa kakhulu kulwakhiwo ngokubanzi.
Uphawu oluPhambili:Ukusebenza kakuhle kakhulu, okunika ukumelana okunamandla kokugoba kunye nokucinezelwa, okwenza ukuba zilungele iikholamu.
IiHEM Beams (Uthotho Olunzima)
Imisebe yeHEMinzima kwaye inamandlaamalungu osapho. I-HEM Beams zii-h-beams ezinzima kwaye zinomthwalo omkhulu we-h-beam. Zineiiflange ezibanzi nezityebileyophakathi kwaba bathathu, kunye nobukhulu bewebhu nabo banda kakhulu.
Izicelo eziqhelekileyo:Iikholamu ezinzima kwizakhiwo ezinemigangatho emininzi, inkxaso yesiseko yoomatshini abanzima, iiprojekthi zobunjineli bokwakha (ezifana neepiers), kunye naso nasiphi na isakhiwo esithwalwa yimithwalo ephezulu kakhulu.
Uphawu oluPhambili:Umthamo womthwalo we-axial ophezulu kunye nokuqina. Ububanzi beflange yabo obukhulu bubonelela ngozinzo olukhulu xa ithintelwa kukugoba.
Izinto Ezibalulekileyo Eziqwalaselweyo Xa Kukhethwa
Ukukhetha phakathi kwe-HEA, HEB, kunye ne-HEM beams kufuna uvavanyo olucokisekileyo lobunjineli. Izinto eziphambili ziquka:
Uhlobo lomthwalo kunye nobukhulu:Imithwalo ye-Axial (compressive) ikhetha amacandelo e-HEB okanye e-HEM, ngelixa iimeko zokugoba ezicocekileyo zinokusebenzisa i-HEA okanye i-HEB.
Ubude beSpan:Ii-span ezinde zihlala zifuna iindawo ezinzulu ukuze zikwazi ukumelana nokugoba ngokwaneleyo.
Iimfuneko zozinzo:Ukuxhathisa ukugoba (kwasekhaya nakwehlabathi) kuphuculiswa ziiflanges ezijiyileyo kunye neeweb ezifumaneka kwicandelo le-HEB kunye ne-HEM.
Iinkcukacha zoQhagamshelo:Ububanzi kunye nobukhulu beflange buchaphazela ukudityaniswa kwe-welding kunye neebholithi.
Imiqobo yoYilo:Indawo ekhoyo inokunciphisa ubunzulu okanye ububanzi becandelo.
Ukuphuculwa kwexabiso kunye nezinto:Injongo kukuhlangabezana nazo zonke iikhrayitheriya zokhuseleko kunye nokusebenza ngecandelo elingabizi kakhulu, ukunciphisa ubunzima bentsimbi iyonke.
Izicelo Eziqhelekileyo Kushishino
Ulwakhiwo lweSakhelo:Umzimba wezakhiwo eziphakamileyo zorhwebo, zemizi-mveliso, nezezindlu.
Ukwakhiwa kweBhulorho:Iigirter kunye nezakhiwo ezixhasayo.
IiMezzanines kunye namaQonga eMizi-mveliso:Iifreyimu zokuxhasa umgangatho ophakamileyo.
Iziseko zoomatshini abanzima:Iziseko ezizinzileyo zeepress, iiturbines, kunye nezixhobo ezinkulu.
Iinkqubo zokuQokelela iiWarehouse:Iifreyimu ezithe nkqo zokugcina izinto ezixineneyo.
Itshasi yeLori kunye neTreyila:Amalungu aphambili esakhelo se-longitudinal.
Itshathi ye-HEA,HEB,HEM
Isiphelo
Ukuqonda umahluko ocacileyo phakathi kwamacandelo e-HEA, HEB, kunye ne-HEM beam kubalulekile kuyilo lwesakhiwo olusebenzayo nolukhuselekileyo kunye nezixhobo zesakhiwo sentsimbi.Imisebe ye-HEAbonelela ngesisombululo esikhaphukhaphu sezinto zesibini.imiqadi ye-HEBisebenza njengehashe elisebenzayo elinokuguquguquka kwiintlobo ngeentlobo zezicelo eziphambili zesakhiwo.Imiqadi yeHEMukubonelela ngokuqina okufunekayo kwiimeko ezinzima kakhulu.
Soloko ujongana neekhowudi zoyilo ezifanelekileyo kwaye usebenzisane neenjineli zesakhiwo ezifanelekileyo ukukhetha iprofayili ye-H beam efanelekileyo kwiprojekthi yakho ethile. Ukhetho olufanelekileyo luqinisekisa ukuthembeka kwesakhiwo, ukusebenza kakuhle kwezinto, kunye nempumelelo yeprojekthi.
