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 nomnotho wezakhiwo kungathuthukiswa ngempumelelo ngokukhethwa okunengqondo nokusetshenziswa kwemishayo ye-H.
