Ama-H-beams ngaphansi kwamazinga aseYurophu ahlukaniswa ngokuya ngomumo wawo we-cross-sectional, usayizi kanye nezakhiwo zemishini. Ngaphakathi kwalolu chungechunge, i-HEA ne-HEB yizinhlobo ezimbili ezivamile, ngayinye enezimo ezithile zohlelo lokusebenza. Ngezansi kunencazelo eningiliziwe yalezi zinhlobo ezimbili, okuhlanganisa ukuhluka kwazo nokusebenza kwazo.
HEAUchungechunge
Uchungechunge lwe-HEA luhlobo lwensimbi ye-H-beam enama-flange amancane afanele izakhiwo zokwakha ezidinga izinga eliphezulu lokusekela. Lolu hlobo lwensimbi luvame ukusetshenziswa ezakhiweni eziphakeme, amabhuloho, imigudu, nezinye izinkambu zobunjiniyela.Umklamo wesigaba se-HEA ubonakala ngobude besigaba esiphakeme kanye newebhu elinganiselwe, eyenza iphumelele ekumelaneni nezikhathi ezinkulu zokugoba.
Umumo wesigaba esiphambanayo: Umumo wesigaba esiphambanayo sochungechunge lwe-HEA uveza umumo ojwayelekile we-H, kodwa onobubanzi obuncane be-flange.
Ibanga losayizi: Ama-flange abanzi ngokuqhathaniswa kodwa ama-web mancane, futhi ukuphakama kuvame ukuhluka ukusuka ku-100mm kuya ku-1000mm, isb, ubukhulu besigaba esiphambanayo se-HEA100 cishe bungu-96 × 100 × 5.0 × 8.0mm (ubude × ububanzi × ukujiya kwewebhu × ukujiya kweflange).
Isisindo semitha (isisindo imitha): Njengoba inombolo yemodeli ikhula, isisindo semitha siyanda. Isibonelo, i-HEA100 inesisindo semitha esicishe sibe ngu-16.7 KG, kuyilapho i-HEA1000 inesisindo semitha esiphezulu kakhulu.
Amandla: Amandla aphezulu nokuqina, kodwa umthamo ophansi wokuthwala umthwalo uma uqhathaniswa nochungechunge lwe-HEB.
Ukuzinza: Ama-flange amancane namawebhu abuthakathaka uma kuqhathaniswa nokuzinza lapho engaphansi kwengcindezi kanye nezikhathi zokugoba, nakuba asengakwazi ukuhlangabezana nezidingo eziningi zesakhiwo ngaphakathi kwebanga lokuklama eliphusile.
Ukumelana ne-Torsional: Ukumelana ne-torsional kulinganiselwe futhi kulungele izakhiwo ezingadingi amandla aphezulu e-torsional.
Izicelo: Ngenxa yobude bayo besigaba esiphakeme namandla amahle okugoba, izigaba ze-HEA zivame ukusetshenziswa lapho isikhala sibucayi, njengasesakhiweni esiyinhloko sezakhiwo eziphakeme kakhulu.
Izindleko zokukhiqiza: Izinto ezisetshenziswayo zincane kakhulu, inqubo yokukhiqiza ilula, futhi izidingo zemishini yokukhiqiza ziphansi, ngakho-ke izindleko zokukhiqiza ziphansi.
Intengo Yemakethe: Emakethe, ngobude nobuningi obufanayo, intengo ivamise ukuba ngaphansi kunochungechunge lwe-HEB, olunosizo oluthile lwezindleko futhi lufanele amaphrojekthi angabizi kakhulu.
HEBUchungechunge
Uchungechunge lwe-HEB, ngakolunye uhlangothi, luyi-wide-flange H-beam, enomthamo ophezulu wokuthwala umthwalo uma kuqhathaniswa ne-HEA. Lolu hlobo lwensimbi lufaneleka ngokukhethekile ezakhiweni ezinkulu zokwakha, amabhuloho, imibhoshongo, nezinye izinhlelo zokusebenza lapho imithwalo emikhulu idinga ukuthwalwa.
Ukuma Kwesigaba: Nakuba i-HEB iphinde ibonise umumo we-H ofanayo, inobubanzi obubanzi be-flange kune-HEA, ehlinzeka ngokuzinza okungcono namandla okuthwala umthwalo.
Ububanzi besayizi: i-flange ibanzi futhi iwebhu ishubile, ububanzi bobude busuka ku-100mm kuye ku-1000mm, njengokucaciswa kwe-HEB100 cishe ku-100×100×6×10mm, ngenxa ye-flange ebanzi, indawo yesigaba esiphambanayo kanye nesisindo semitha se-HEB sizoba sikhulu kunaleso esingaphansi kwemodeli ye-HEA ehambisanayo.
Isisindo semitha: Isibonelo, isisindo semitha se-HEB100 singaba ngu-20.4KG, okuwukunyuka uma kuqhathaniswa ne-16.7KG ye-HEA100; lo mehluko uba sobala kakhulu njengoba inombolo yemodeli ikhula.
Amandla: Ngenxa ye-flange ebanzi kanye newebhu ewugqinsi, inamandla aphakeme aqinile, indawo yokukhiqiza namandla okugunda, futhi iyakwazi ukumelana nokugoba okukhulu, ukugunda kanye netorque.
Ukuzinza: Uma kungaphansi kwemithwalo emikhulu namandla angaphandle, kubonisa ukuzinza okungcono futhi akujwayele ukuguquguquka nokungazinzi.
Ukusebenza kwe-Torsional: i-flange ebanzi kanye newebhu ebanzi iyenza ibe phezulu ekusebenzeni kwe-torsional, futhi ingamelana ngokuphumelelayo namandla okuguquguquka okungenzeka ngesikhathi sokusetshenziswa kwesakhiwo.
Izicelo: Ngenxa yokuvuleka kwayo okubanzi nosayizi omkhulu wezigaba eziphambanayo, izigaba ze-HEB zilungele izinhlelo zokusebenza lapho kudingeka khona ukwesekwa okwengeziwe nokuzinza, njengengqalasizinda yemishini esindayo noma ukwakhiwa kwamabhuloho abanzi.
Izindleko zokukhiqiza: Kudingeka izinto ezingavuthiwe ezengeziwe, futhi inqubo yokukhiqiza idinga amathuluzi nezinqubo ezengeziwe, njengokucindezela okukhulu nokulawula okunembe kakhulu ngesikhathi sokugingqika, okuholela ezindlekweni zokukhiqiza eziphakeme.
Intengo yemakethe: Izindleko zokukhiqiza eziphakeme ziholela enanini lemakethe uma kuqhathaniswa, kodwa kumaphrojekthi anezidingo eziphezulu zokusebenza, isilinganiso senani/sokusebenza sisaphezulu kakhulu.
Ukuqhathanisa okuphelele
Lapho ukhetha phakathiHea / Heb, ukhiye usezidingweni zephrojekthi ethile. Uma iphrojekthi idinga izinto ezinokumelana okuhle nokugoba futhi ingathinteki kakhulu yizingqinamba zesikhala, i-HEA ingaba yisinqumo esingcono. Ngokuphambene, uma iphrojekthi okugxilwe kuyo kuwukunikeza amandla okubopha aqinile nokuzinza, ikakhulukazi ngaphansi kwemithwalo ebalulekile, i-HEB izofaneleka kakhulu.
Kubalulekile futhi ukuqaphela ukuthi kungase kube nomehluko omncane wokucaciswa phakathi kwamaphrofayela e-HEA kanye ne-HEB akhiqizwa abakhiqizi abahlukene, ngakho-ke kubalulekile ukuhlola kabili amapharamitha afanelekile ukuze uqiniseke ukuthi ayahambisana nezidingo zokuklama phakathi nenqubo yokuthenga nokusetshenziswa kwangempela. Ngesikhathi esifanayo, noma yiluphi uhlobo olukhethiwe, kufanele kuqinisekiswe ukuthi insimbi ekhethiwe ihambisana nezinhlinzeko zamazinga afanele aseYurophu afana ne-EN 10034 futhi isiphumelele isitifiketi sekhwalithi esihambisanayo. Lezi zinyathelo zisiza ukuqinisekisa ukuphepha nokuthembeka kwesakhiwo sokugcina.
