Uhlobo lwaseYurophu lwe-H-beam yeentlobo ze-HEA kunye ne-HEB zineentlukwano eziphawulekayo kwimilo enqamlezayo, ubungakanani kunye nokusetyenziswa.
HEA series
I-HEA yiflange eshushu eqengqelekayoH-umqadingokomgangatho waseYurophu, kunye ne "H"-shaped cross-sectional shape, ubuso obusebenza obufanayo (iiwebhu) kunye neepleyiti ezimbini zeflange. Uhlobo lwe-HEA lwe-H-beam lubonakaliswe ngama-flanges amancinci kunye nokuphakama okukhulu, okwenza kube yinto efanelekileyo kwiziganeko ezinexesha elikhulu lokugoba, njengamabhuloho, izakhiwo eziphakamileyo, njl.1. Ngokukodwa, i-HEA series steels idla ngokusetyenziselwa izakhiwo ezifuna amandla aphezulu kunye nokuqina, njengezakhelo zokwakha ezenza kakuhle phantsi kwemithwalo ethe nkqo kunye nethe tye.
HEB series
Ngokwahlukileyo, uhlobo lwe-HEB lwe-H-beam luyi-hot-rolled ribbed wide-flange H-beam phantsi komgangatho waseYurophu, kodwa iimpawu zayo zahlukile kwi-HEA. Indawo enqamlezileyo ye-HEB uhlobo lwe-H-beam inokuba ncinci kancinci kune-HEA, kodwa ububanzi bayo be-flange bubanzi kwaye iwebhu ibanzi, enika i-HEB uhlobo lwe-H-beam ukusebenza okungcono koxinzelelo kwaye ilungele iimeko zesicelo ezifuna ukuqina okukhulu kwe-flange2. Oku kuthetha ukuba kwezinye iimeko, nangona icross-amacandeloIndawo yeHEB incinci, inokubonelela ngenkxaso eyomeleleyo ngenxa yeflange yayo ebanzi kunye newebhu engqindilili.
1. Imilinganiselo ye-cross-sectional kunye neempawu zejometri
•HEA series (i-H-beam ekhaphukhaphu)
▪ Iiflange ezicutheneyo nezicekethekileyo (iiflange) kunye neentambo ezibhityileyo (iipleyiti ezithe nkqo eziphakathi).
▪ Ubunzima bokukhanya ngobude beyunithi kunye nommandla omncinci onqamlezileyo.
▪ Umzuzu ophantsi we-inertia (ukumelana nokugoba) kunye nemodyuli yecandelo, ilungele iimeko zomthwalo ophakathi.
•HEB series (standard H-beam)
▪ Iiflange ezibanzi nezingqindilili kunye newebhu engqindilili.
▪Ubunzima beyunithi obuphezulu kunye nokwandisa kakhulu indawo enqamlezileyo.
▪ Umzuzu ophakamileyo we-inertia kunye nemodyuli yecandelo, ukugoba okunamandla kunye nokumelana noxinzelelo, ilungele izakhiwo zomthwalo onzima.
3. Iipropati zoomatshini kunye neemeko zokusetyenziswa
HEA
▪Ifanele imithwalo ekhanyayo ukuya kwephakathi, efana nefreyimu yezityalo ezilula, amaqonga amancinane okanye izakhiwo ezingathwali mthwalo.
▪ Uqoqosho oluhle, ukonga iindleko zezinto eziphathekayo.
HEB
▪ Isetyenziswa kwiimeko ezinomthwalo onzima, njengemiqadi engundoqo yebhulorho, iintsika zezakhiwo eziphakamileyo okanye izixhaso zoomatshini abakhulu.
▪Ukuqina okuphezulu kunye namandla, kodwa ixabiso eliphezulu lezinto eziphathekayo.
4. Olunye uthotho lwe-H-beam yaseYurophu
▪Uchungechunge lwe-HEM: ii-flanges ezityebileyo kunye neewebhu, ezenzelwe imithwalo enzima (njengeziseko zezixhobo ezinzima zoshishino).
▪I-IPN/IPE series: Ifana ne-HEA/HEB, kodwa nge-parallel flange design (akukho slope kwicala langaphakathi leflange).
Iindawo zesicelo
Ngenxa yokungafani kwezi mpawu zingentla, ukusetyenziswa kwe-HEA kunye ne-HEB uhlobo lwe-H-beams kubunjineli bobunjineli kwakhona kugxininisa kwiinkalo ezahlukeneyo. I-HEA H-beam ifaneleke ngakumbi kwiindawo ezifuna ukuqina okuphezulu kunye namandla aphezulu, njengenkqubo yokuxhasa isiseko sezakhiwo ezinkulu okanye ityhubhu engundoqo yezakhiwo eziphakamileyo. I-HEB H-beam, ngenxa yobubanzi beflange enkulu kunye newebhu etyebileyo, isebenza kakuhle ngakumbi xa iphantsi kwemithwalo yoxinzelelo olukhulu. Ke ngoko, isetyenziswa rhoqo kwisiseko sesiseko soomatshini abanzima okanye izityalo zoshishino ezineemfuno eziphezulu zokuthwala umthamo.
