Amazinga namamodeli we-H-beams Emazweni Ahlukahlukene

I-H-beam iwuhlobo lwensimbi ende enesiphambano esimise okwe-H, esiqanjwe ngenxa yokuthi umumo wayo wesakhiwo ufana nohlamvu lwesiNgisi oluthi “H”. Inamandla aphezulu kanye nezakhiwo ezinhle zemishini, futhi isetshenziswa kabanzi ekwakhiweni, ebhulohweni, ekwakhiweni kwemishini nakweminye imikhakha.

I-Chinese National Standard (GB)

Ama-H-beams e-China akhiqizwa kakhulu futhi ahlukaniswe ngokusekelwe ku-Hot Rolled H-beams kanye ne-Sectional T-beams (GB/T 11263-2017). Ngokuya ngobubanzi be-flange, ingahlukaniswa nge-wide-flange H-beam (HW), i-medium-flange H-beam (HM) kanye ne-narrow-flange H-beam (HN). Isibonelo, i-HW100×100 imele i-wide flange H-beam enobubanzi be-flange obungu-100mm nobude obungu-100mm; I-HM200×150 imele i-H-beam ephakathi nendawo enobubanzi obungu-200mm nobude obungu-150mm. Ngaphezu kwalokho, kunezinsimbi eziqinile ezakhiwe ngamakhaza nezinye izinhlobo ezikhethekile zemishayo ye-H.

Amazinga aseYurophu (EN)

I-H-beams e-Europe ilandela uchungechunge lwamazinga ase-Europe, afana ne-EN 10034 kanye ne-EN 10025, acacisa ngokucaciswa kobukhulu, izidingo zezinto ezibonakalayo, izakhiwo zemishini, ikhwalithi yendawo kanye nemithetho yokuhlola ye-H-imishayo. Izisekelo ezijwayelekile zaseYurophu ze-H-imishayo zihlanganisa uchungechunge lwe-HEA, HEB kanye ne-HEM; uchungechunge lwe-HEA luvame ukusetshenziselwa ukumelana namandla e-axial naqondile, njengasezakhiwo eziphakeme; uchungechunge lwe-HEB lufanele izakhiwo ezincane kuya ezimaphakathi; futhi uchungechunge lwe-HEM lufanele izinhlelo zokusebenza ezidinga umklamo wesisindo esilula ngenxa yobude bayo obuncane nesisindo. Uchungechunge ngalunye lutholakala ngamasayizi ahlukahlukene.
Uchungechunge lwe-HEA: HEA100, HEA120, HEA140, HEA160, HEA180, HEA200, njll.
HEB Series: HEB100, HEB120, HEB140, HEB160, HEB180, HEB200, njll.
I-HEM Series: HEM100, HEM120, HEM140, HEM160, HEM180, HEM200, njll.

I-American Standard H beam(ASTM/AISC)

I-American Society for Testing and Materials (ASTM) ithuthukise izindinganiso ezinemininingwane zemishayo ye-H, njenge-ASTM A6/A6M. Amamodeli we-American Standard H-beam avamise ukuvezwa ngefomethi ye-Wx noma i-WXxxy, isb, i-W8 x 24, lapho u-“8” ebhekisela kububanzi be-flange ngama-intshi futhi “24” isho isisindo ngefithi ngalinye lobude (amaphawundi). Ngaphezu kwalokho, kukhona i-W8 x 18, W10 x 33, W12 x 50, njll. Amabanga amandla avamile akabushaI-ASTM A36, A572, njll.

I-British Standard (BS)

Ama-H-beams ngaphansi Kwezinga LaseBrithani alandela izicaciso ezifana ne-BS 4-1:2005+A2:2013. Izinhlobo zifaka i-HEA, HEB, HEM, HN nezinye eziningi, ngochungechunge lwe-HN olubeka ukugcizelela okukhethekile ekhonweni lokumelana namandla avundlile naqondile. Inombolo yemodeli ngayinye ilandelwa inombolo ukukhombisa imingcele kasayizi othize, isb. HN200 x 100 ikhombisa imodeli enobude nobubanzi obuthile.

I-Japanese Industrial Standard (JIS)

I-Japan Industrial Standard (JIS) ye-H-beams ibhekisela ikakhulukazi ezingeni le-JIS G 3192, eliqukethe amabanga amaningana njengeI-SS400, I-SM490, njll. I-SS400 iyinsimbi evamile yesakhiwo efaneleka imisebenzi yokwakha evamile, kuyilapho i-SM490 inikeza amandla aphakeme aqinile futhi ifanele ukusetshenziswa komsebenzi osindayo. Izinhlobo zivezwa ngendlela efanayo neyaseShayina, isb. H200×200, H300×300, njll. Ubukhulu obunjengobude nobubanzi be-flange bubonisiwe.

I-German Industrial Standards (DIN)

Ukukhiqizwa kwe-H-beams eJalimane kusekelwe kumazinga afana ne-DIN 1025, isibonelo uchungechunge lwe-IPBL. Lawa mazinga aqinisekisa ikhwalithi nokuvumelana kwemikhiqizo futhi afanele uhla olubanzi lwezicelo zezimboni.

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

Ukufingqa, nakuba amazinga nezinhlobo zemishayo ye-H zihluka kuye ngamazwe kanye nesifunda ngesifunda, zabelana ngomgomo ofanayo wokuqinisekisa ikhwalithi yomkhiqizo nokuhlangabezana nezidingo ezihlukahlukene zobunjiniyela. Eqinisweni, lapho ukhetha i-H-beam efanele, kuyadingeka ukucabangela izidingo ezithile zephrojekthi, izimo zemvelo kanye nezingqinamba zesabelomali, kanye nokuhambisana namakhodi wokwakha wendawo kanye nezindinganiso. Ukuphepha, ukuqina kanye nomnotho wezakhiwo kungathuthukiswa ngempumelelo ngokukhethwa okunengqondo nokusetshenziswa kwemishayo ye-H.
