I-H-beams phantsi kwemigangatho yaseYurophu ihlelwe ngokwemilo ye-cross-sectional shape, ubukhulu kunye neempawu zomatshini. Ngaphakathi kolu chungechunge, i-HEA kunye ne-HEB zimbini iindidi eziqhelekileyo, nganye kuzo ineemeko ezithile zesicelo. Apha ngezantsi kukho inkcazo eneenkcukacha yale mifuziselo mibini, kubandakanywa iyantlukwano kunye nokusebenza kwayo.
HEAUthotho
Uchungechunge lwe-HEA luhlobo lwentsimbi ye-H-beam ene-flanges encinci efanelekileyo kwizakhiwo zokwakha ezifuna inkxaso ephezulu. Olu hlobo lwentsimbi luqhele ukusetyenziswa kwizakhiwo eziphakamileyo, iibhuloho, iitonela, kunye nezinye iindawo zobunjineli.Uyilo lwecandelo le-HEA lubonakaliswe ngokuphakama kwecandelo eliphezulu kunye newebhu encinci, eyenza ukuba iphumelele ekujonganeni namaxesha amakhulu okugoba.
Ubume becandelo lomnqamlezo: Ubume becandelo lomnqamlezo loluhlu lwe-HEA lubonisa ubume obuqhelekileyo be-H, kodwa bunobubanzi obumxinwa kakhulu.
Uluhlu lobungakanani: Iiflange zibanzi kodwa iiwebhu zincinci, kwaye ukuphakama ngokuqhelekileyo ukusuka kwi-100mm ukuya kwi-1000mm, umzekelo, imilinganiselo ye-cross-section ye-HEA100 imalunga ne-96 × 100 × 5.0 × 8.0mm (ubude × ububanzi × ubukhulu bewebhu × ubukhulu be-flange).
Ubunzima bemitha (ubunzima ngemitha): Njengoko inani lemodeli linyuka, ubunzima bemitha buyanda. Umzekelo, i-HEA100 inobunzima beemitha malunga ne-16.7 KG, ngelixa i-HEA1000 inobunzima obuphezulu bemitha.
Amandla: Amandla aphezulu kunye nokuqina, kodwa umthamo ophantsi wokuthwala umthwalo xa uthelekiswa nochungechunge lwe-HEB.
Uzinzo: Iiflange ezibhityileyo kunye neewebhu zibuthathaka ngokwentelekiso malunga nozinzo xa ziphantsi koxinzelelo kunye namaxesha okugoba, nangona zisenokuhlangabezana neemfuno ezininzi zesakhiwo ngaphakathi koluhlu loyilo olufanelekileyo.
Ukumelana ne-Torsional: Ukuxhathisa kwe-torsional kulinganiselwe kwaye ifanelekile kwizakhiwo ezingadingi amandla aphezulu.
Izicelo: Ngenxa yokuphakama kwecandelo eliphezulu kunye nokugoba okulungileyo, amacandelo e-HEA ahlala esetyenziswa apho indawo ibaluleke kakhulu, njengakwisakhiwo esisisiseko sezakhiwo eziphakamileyo.
Iindleko zokuvelisa: Izinto ezisetyenzisiweyo zincinci, inkqubo yokuvelisa ilula, kwaye iimfuno zezixhobo zokuvelisa ziphantsi, ngoko ixabiso lemveliso liphantsi.
Ixabiso leMakethi: Kwimarike, ubude kunye nobungakanani obufanayo, ixabiso lihlala liphantsi kune-HEB series, enenzuzo ethile yeendleko kwaye ifanelekile kwiiprojekthi ezingabizi kakhulu.
HEBUthotho
Uchungechunge lwe-HEB, ngakolunye uhlangothi, i-wide-flange H-beam, enomthamo ophezulu wokuthwala umthwalo xa kuthelekiswa ne-HEA. Olu hlobo lwensimbi lufanelekile ngokukodwa kwizakhiwo ezinkulu zokwakha, iibhuloho, iinqaba, kunye nezinye izicelo apho imithwalo emikhulu kufuneka iqhutywe.
Ubume beCandelo: Nangona i-HEB iphinda ibonise ukumila okufanayo kwe-H, inobubanzi obubanzi be-flange kune-HEA, enika uzinzo olungcono kunye nomthamo wokuthwala umthwalo.
Uluhlu lobungakanani: i-flange ibanzi kwaye iwebhu ibanzi, ububanzi bobude buvela kwi-100mm ukuya kwi-1000mm, njengokucaciswa kwe-HEB100 malunga ne-100 × 100 × 6 × 10mm, ngenxa ye-flange ebanzi, indawo yecandelo lomnqamlezo kunye nobunzima beemitha ze-HEB buya kuba bukhulu kunelo lenombolo ehambelana nemodeli ye-HEA efanayo.
Ubunzima beemitha: Umzekelo, ubunzima bemitha ye-HEB100 malunga ne-20.4KG, okunyukayo xa kuthelekiswa ne-16.7KG ye-HEA100; lo mahluko ubonakala ngakumbi njengoko inani lemodeli lisanda.
Amandla: Ngenxa ye-flange ebanzi kunye ne-web engqindilili, inamandla aphezulu okuqina, indawo yesivuno kunye namandla okucheba, kwaye iyakwazi ukumelana nokugoba okukhulu, ukucheba kunye ne-torque.
Ukuzinza: Xa uphantsi kwemithwalo emikhulu kunye namandla angaphandle, kubonisa ukuzinza okungcono kwaye kuncinci kwi-deformation kunye nokungazinzi.
Ukusebenza kwe-Torsional: i-flange ebanzi kunye ne-web engqingqwa yenza ukuba ibe phezulu ekusebenzeni kwe-torsional, kwaye iyakwazi ukuxhathisa ngokufanelekileyo i-torsional force enokuthi yenzeke ngexesha lokusetyenziswa kwesakhiwo.
Izicelo: Ngenxa yee-flanges zayo ezibanzi kunye nobukhulu becandelo elinqamlezayo, amacandelo e-HEB afanelekile kwizicelo apho inkxaso eyongezelelweyo kunye nokuzinza kuyadingeka, njengeziseko zoomatshini abanzima okanye ukwakhiwa kweebhulorho ezinkulu.
Iindleko zokuvelisa: Izinto ezingaphezulu ezifunekayo, kwaye inkqubo yokuvelisa ifuna izixhobo ezininzi kunye neenkqubo, ezifana noxinzelelo olukhulu kunye nolawulo oluchanekileyo ngexesha lokuqengqeleka, okubangela iindleko eziphezulu zokuvelisa.
Ixabiso lemarike: Iindleko eziphezulu zemveliso zikhokelela kwixabiso eliphezulu lemarike, kodwa kwiiprojekthi ezineemfuno eziphezulu zokusebenza, umlinganiselo wexabiso / wokusebenza usephezulu kakhulu.
Uthelekiso olubanzi
Xa ukhetha phakathiHea / Heb, undoqo uxhomekeke kwiimfuno zeprojekthi ethile. Ukuba iprojekthi idinga izinto eziphathekayo ezinokumelana nokugoba okulungileyo kwaye ayichatshazelwa kakhulu yimiqobo yendawo, ngoko i-HEA inokuba lolona khetho lungcono. Ngokuchasene noko, ukuba ugxininiso lweprojekthi kukubonelela ngesakhono esiqinileyo sokuqina kunye nokuzinza, ngakumbi phantsi kwemithwalo ebalulekileyo, i-HEB iya kufaneleka ngakumbi.
Kwakhona kubalulekile ukuqaphela ukuba kunokubakho ukungafani okucacileyo okuncinci phakathi kweeprofayili ze-HEA kunye ne-HEB eziveliswe ngabavelisi abahlukeneyo, ngoko ke kubalulekile ukujonga kabini iiparitha ezifanelekileyo ukuqinisekisa ukuthotyelwa kweemfuno zoyilo ngexesha lokuthenga kunye nokusetyenziswa kwangempela. Ngexesha elifanayo, naluphi na uhlobo olukhethiweyo, kufuneka kuqinisekiswe ukuba insimbi ekhethiweyo ihambelana nemimiselo yemigangatho yaseYurophu echaphazelekayo efana ne-EN 10034 kwaye idlulise isiqinisekiso somgangatho ohambelanayo. La manyathelo anceda ukuqinisekisa ukhuseleko kunye nokuthembeka kwesakhiwo sokugqibela.
