Izindinganiso namamodeli e-H-beams emazweni ahlukahlukene

I-H-beam uhlobo lwensimbi ende enesigaba esifana no-H, esiqanjwe ngokuthi isimo sayo sesakhiwo sifana nohlamvu lwesiNgisi oluthi “H”. Inamandla aphezulu kanye nezakhiwo ezinhle zemishini, futhi isetshenziswa kabanzi ekwakheni, ebhuloho, ekukhiqizeni imishini nakwezinye izinkambu.

Izinga Likazwelonke LaseShayina (GB)

Imishayo ye-H eShayina ikhiqizwa kakhulu futhi ihlukaniswe ngokusekelwe kumishayo ye-H egoqekile eshisayo kanye nemishayo ye-T ehlukanisiwe (GB/T 11263-2017). Kuye ngobubanzi beflange, ingahlukaniswa ibe yi-H-beam ebanzi (HW), i-H-beam ebanzi (HM) kanye ne-H-beam ebanzi (HN). Isibonelo, i-HW100×100 imelela i-H-beam ebanzi enobubanzi beflange obuyi-100mm kanye nokuphakama okungu-100mm; i-HM200×150 imelela i-H-beam ebanzi enobubanzi beflange obuyi-200mm kanye nokuphakama okungu-150mm. Ngaphezu kwalokho, kunensimbi encane eyakhiwe ngodonga olubandayo kanye nezinye izinhlobo ezikhethekile zemishayo ye-H.

Izindinganiso zaseYurophu (EN)

Imishayo ye-H eYurophu ilandela uchungechunge lwezindinganiso zaseYurophu, njenge-EN 10034 kanye ne-EN 10025, ezichaza ngokuningiliziwe izici zobukhulu, izidingo zezinto ezibonakalayo, izakhiwo zemishini, ikhwalithi yobuso kanye nemithetho yokuhlola yemishayo ye-H. Imishayo ye-H ejwayelekile yaseYurophu ifaka uchungechunge lwe-HEA, HEB kanye ne-HEM; uchungechunge lwe-HEA luvame ukusetshenziselwa ukumelana namandla axial kanye naqondile, njengasezakhiweni eziphakeme; uchungechunge lwe-HEB lufanele izakhiwo ezincane kuya kweziphakathi; kanti uchungechunge lwe-HEM lufanelekela izinhlelo zokusebenza ezidinga umklamo wesisindo esilula ngenxa yokuphakama nesisindo salo esincane. Uchungechunge ngalunye lutholakala ngobukhulu obuhlukahlukene obuhlukene.
Uchungechunge lwe-HEA: HEA100, HEA120, HEA140, HEA160, HEA180, HEA200, njll.
Uchungechunge lwe-HEB: HEB100, HEB120, HEB140, HEB160, HEB180, HEB200, njll.
Uchungechunge lwe-HEM: HEM100, HEM120, HEM140, HEM160, HEM180, HEM200, njll.

Umsebe we-H ojwayelekile waseMelika(ASTM/AISC)

I-American Society for Testing and Materials (ASTM) ithuthukise amazinga anemininingwane ye-H-beams, njenge-ASTM A6/A6M. Amamodeli e-American Standard H-beam avame ukuvezwa ngefomethi ye-Wx noma ye-WXxxy, isib. i-W8 x 24, lapho u-“8” ebhekisela ebubanzini be-flange ngamasentimitha kanye no-“24” ekhomba isisindo ngonyawo lobude (amakhilogremu). Ngaphezu kwalokho, kune-W8 x 18, W10 x 33, W12 x 50, njll. Amandla avamile akabushaI-ASTM A36, A572, njll.

Izinga laseBrithani (BS)

Ama-H-beam ngaphansi kwe-British Standard alandela imininingwane efana ne-BS 4-1:2005+A2:2013. Izinhlobo zifaka phakathi i-HEA, i-HEB, i-HEM, i-HN nezinye eziningi, kanti uchungechunge lwe-HN lugcizelela kakhulu ikhono lokumelana namandla avundlile naqondile. Inombolo ngayinye yemodeli ilandelwa yinombolo ukukhombisa amapharamitha athile osayizi, isib. i-HN200 x 100 ikhombisa imodeli enokuphakama nobubanzi obuthile.

Izinga Lezimboni LaseJapan (i-JIS)

I-Japanese Industrial Standard (JIS) ye-H-beams ibhekisela kakhulu ku-JIS G 3192 standard, equkethe amamaki amaningana afana nalawa:SS400, SM490, njll. I-SS400 iyinsimbi yesakhiwo ejwayelekile efanelekela imisebenzi yokwakha ejwayelekile, kuyilapho i-SM490 inikeza amandla aphezulu okudonseka futhi ifanelekela ukusetshenziswa okunzima. Izinhlobo zivezwa ngendlela efanayo neyaseShayina, isib. i-H200×200, i-H300×300, njll. Ubukhulu obufana nokuphakama nobubanzi be-flange buyaboniswa.

Izindinganiso Zezimboni ZaseJalimane (i-DIN)

Ukukhiqizwa kwe-H-beams eJalimane kusekelwe ezindinganisweni ezifana ne-DIN 1025, isibonelo uchungechunge lwe-IPBL. Lezi zindinganiso ziqinisekisa ikhwalithi kanye nokuvumelana kwemikhiqizo futhi zifanelekela izinhlobo eziningi zezicelo zezimboni.

I-Australia
Amazinga: AS/NZS 1594 njll.
Amamodeli: isib. 100UC14.8, 150UB14, 150UB18, 150UC23.4, njll.

Ngamafuphi, yize amazinga nezinhlobo ze-H-beams zihluka kuye ngezwe nesifunda nesifunda, zabelana ngomgomo ofanayo wokuqinisekisa ikhwalithi yomkhiqizo nokuhlangabezana nezidingo zobunjiniyela ezahlukahlukene. Empeleni, lapho ukhetha i-H-beam efanele, kubalulekile ukucabangela izidingo ezithile zephrojekthi, izimo zemvelo kanye nemikhawulo yesabelomali, kanye nokuhambisana nemithetho nezindinganiso zokwakha zendawo. Ukuphepha, ukuqina kanye nomnotho wezakhiwo kungathuthukiswa ngempumelelo ngokukhetha okunengqondo nokusetshenziswa kwe-H-beams.
