Imishayo ye-H ngaphansi kwezindinganiso zaseYurophu ihlukaniswe ngokwesimo sayo esinqamula isigaba, usayizi kanye nezakhiwo zemishini. Ngaphakathi kwalolu chungechunge, i-HEA kanye ne-HEB ziyizinhlobo ezimbili ezivamile, ngayinye yazo inezimo ezithile zokusetshenziswa. Ngezansi kunencazelo eningiliziwe yalezi zinhlobo ezimbili, okuhlanganisa umehluko wazo kanye nokusebenza kwazo.
I-HEAUchungechunge
Uchungechunge lwe-HEA luhlobo lwensimbi ye-H-beam enama-flange amancane afanelekela izakhiwo zokwakha ezidinga ukwesekwa okuphezulu. Lolu hlobo lwensimbi luvame ukusetshenziswa ezakhiweni eziphakeme, amabhuloho, imigudu, kanye neminye imikhakha yobunjiniyela. Umklamo wesigaba se-HEA ubonakala ngokuphakama kwesigaba esiphakeme kanye newebhu encane, okwenza kube ngcono ekumelaneni nezikhathi ezinkulu zokugoba.
Ukuma kwesigaba esiphambeneyo: Ukuma kwesigaba esiphambeneyo sochungechunge lwe-HEA kuveza ukuma kwe-H okuvamile, kodwa ngobubanzi be-flange obuncane.
Ububanzi bosayizi: Ama-flange abanzi kakhulu kodwa ama-webs mancane, futhi ukuphakama kuvame ukuba phakathi kuka-100mm no-1000mm, isib., ubukhulu be-HEA100 bungaba ngu-96 × 100 × 5.0 × 8.0mm (ukuphakama × ububanzi × ubukhulu be-web × ubukhulu be-flange).
Isisindo semitha (isisindo ngemitha): Njengoba inombolo yemodeli ikhula, isisindo semitha naso siyanda. Isibonelo, i-HEA100 inesisindo semitha esingaba ngu-16.7 KG, kuyilapho i-HEA1000 inesisindo semitha esiphezulu kakhulu.
Amandla: Amandla aphezulu nokuqina, kodwa amandla okuthwala umthwalo aphansi uma kuqhathaniswa nochungechunge lwe-HEB.
Ukuzinza: Ama-flange nama-web amancane kakhulu abuthakathaka ngokwezinga lokuzinza uma ecindezelwa futhi egoba, yize esakwazi ukuhlangabezana nezidingo eziningi zesakhiwo ngaphakathi kobubanzi bomklamo obufanele.
Ukumelana nokugoba: Ukumelana nokugoba kulinganiselwe futhi kufaneleka ezakhiweni ezingadingi amandla aphezulu okugoba.
Ukusetshenziswa: Ngenxa yokuphakama kwayo okuphezulu kwesigaba kanye namandla amahle okugoba, izingxenye ze-HEA zivame ukusetshenziswa lapho isikhala sibaluleke khona, njengasesimeni esiyinhloko sezakhiwo eziphakeme.
Izindleko zokukhiqiza: Izinto ezisetshenzisiwe zincane kakhulu, inqubo yokukhiqiza ilula kakhulu, futhi izidingo zemishini yokukhiqiza ziphansi kakhulu, ngakho-ke izindleko zokukhiqiza ziphansi kakhulu.
Intengo Yemakethe: Emakethe, ngobude nobuningi obufanayo, intengo ivame ukuba ngaphansi kunochungechunge lwe-HEB, olunezinzuzo ezithile zezindleko futhi olufanele amaphrojekthi azwela izindleko.
I-HEBUchungechunge
Ngakolunye uhlangothi, uchungechunge lwe-HEB luyi-H-beam ebanzi, enekhono eliphezulu lokuthwala umthwalo uma kuqhathaniswa ne-HEA. Lolu hlobo lwensimbi lufaneleka kakhulu ezakhiweni ezinkulu zezakhiwo, amabhuloho, imibhoshongo, nezinye izinhlelo zokusebenza lapho kudingeka khona imithwalo emikhulu.
Isimo Sesigaba: Nakuba i-HEB nayo ibonisa isimo esifanayo se-H, inobubanzi be-flange obubanzi kune-HEA, okunikeza ukuzinza okungcono kanye nomthamo wokuthwala umthwalo.
Ububanzi bosayizi: i-flange ibanzi futhi i-web ikhuluphele, ububanzi bokuphakama busukela ku-100mm kuya ku-1000mm, njengoba incazelo ye-HEB100 icishe ibe yi-100×100×6×10mm, ngenxa ye-flange ebanzi, indawo yesigaba esiphambeneyo kanye nesisindo semitha se-HEB kuzoba kukhulu kunemodeli ye-HEA ehambisanayo ngaphansi kwenombolo efanayo.
Isisindo semitha: Isibonelo, isisindo semitha se-HEB100 singaba ngu-20.4KG, okuwukukhula uma kuqhathaniswa no-16.7KG we-HEA100; lo mehluko uba sobala kakhulu njengoba inani lemodeli likhula.
Amandla: Ngenxa ye-flange ebanzi kanye ne-web ejiyile, inamandla aphezulu okudonseka, iphuzu lokukhipha kanye namandla okushefa, futhi iyakwazi ukumelana nokugoba okukhulu, ukushefa kanye ne-torque.
Ukuzinza: Uma ibhekene nemithwalo emikhulu namandla angaphandle, ikhombisa ukuzinza okungcono futhi ayithambekeli kakhulu ekuguqukeni nasekungazinzini.
Ukusebenza kwe-torsional: i-flange ebanzi kanye ne-web ejiyile kwenza kube ngcono ekusebenzeni kwe-torsional, futhi kungamelana ngempumelelo namandla e-torsional angase avele ngesikhathi kusetshenziswa isakhiwo.
Izicelo: Ngenxa yama-flange ayo abanzi kanye nosayizi omkhulu wesigaba esinqamulayo, izingxenye ze-HEB zilungele izinhlelo zokusebenza lapho kudingeka khona ukwesekwa okwengeziwe kanye nokuqina, njengengqalasizinda yemishini esindayo noma ukwakhiwa kwamabhuloho amakhulu.
Izindleko zokukhiqiza: Kudingeka izinto zokusetshenziswa ezengeziwe, futhi inqubo yokukhiqiza idinga imishini nezinqubo ezengeziwe, njengokucindezela okukhulu kanye nokulawula okunembile ngesikhathi sokugoqa, okuholela ezindleleni zokukhiqiza eziphakeme.
Intengo yemakethe: Izindleko zokukhiqiza eziphakeme ziholela entengo yemakethe ephezulu, kodwa kumaphrojekthi anezidingo zokusebenza eziphezulu, isilinganiso sentengo/ukusebenza sisaphezulu kakhulu.
Ukuqhathanisa okuphelele
Uma ukhetha phakathiHea / Heb, isihluthulelo sisezidingweni zephrojekthi ethile. Uma iphrojekthi idinga izinto ezinokumelana okuhle kokugoba futhi ingathinteki kakhulu yimingcele yesikhala, khona-ke i-HEA ingaba yisinqumo esingcono. Ngokuphambene nalokho, uma ukugxila kwephrojekthi kuwukunikeza amandla okuqina okuqinile kanye nokuqina, ikakhulukazi ngaphansi kwemithwalo emikhulu, i-HEB ingaba ngcono kakhulu.
Kubalulekile futhi ukuqaphela ukuthi kungase kube nomehluko omncane wemininingwane phakathi kwamaphrofayili e-HEA ne-HEB akhiqizwa abakhiqizi abahlukene, ngakho-ke kubalulekile ukuhlola kabili amapharamitha afanele ukuqinisekisa ukuhambisana nezidingo zomklamo ngesikhathi senqubo yokuthenga nokusebenzisa yangempela. Ngesikhathi esifanayo, noma yiluphi uhlobo olukhethiwe, kufanele kuqinisekiswe ukuthi insimbi ekhethiwe iyahambisana nezinhlinzeko zezindinganiso zaseYurophu ezifanele njenge-EN 10034 futhi isidlulile isitifiketi sekhwalithi esifanele. Lezi zinyathelo zisiza ukuqinisekisa ukuphepha nokuthembeka kwesakhiwo sokugcina.
