Imigangatho kunye neeModeli ze-H-beams kumazwe ahlukeneyo

I-H-beam luhlobo lwentsimbi ende ene-cross-shaped cross-section, ethiywe ngenxa yokuba imilo yayo yesakhiwo ifana nonobumba wesiNgesi "H". Inamandla aphezulu kunye neempawu ezintle zoomatshini, kwaye isetyenziswa ngokubanzi kulwakhiwo, ibhulorho, ukwenziwa koomatshini kunye nezinye iindawo.

Umgangatho weSizwe waseTshayina (GB)

Imiqadi e-H e-China iveliswa ngokukodwa kwaye ihlelwe ngokusekelwe kwi-Hot Rolled H-beams kunye ne-Sectional T-beams (GB / T 11263-2017). Ngokuxhomekeke kububanzi beflange, inokuthi ihlelwe kwi-wide-flange H-beam (HW), i-medium-flange H-beam (HM) kunye ne-flange-flange H-beam (HN). Ngokomzekelo, i-HW100 × 100 imele i-flange ebanzi ye-H-beam kunye nobubanzi be-flange ye-100mm kunye nobude be-100mm; I-HM200 × 150 imele i-Flange ephakathi kwe-H-beam kunye nobubanzi be-flange ye-200mm kunye nobude be-150mm. Ukongezelela, kukho intsimbi epholileyo epholileyo kunye nezinye iindidi ezikhethekileyo ze-H-beams.

Imigangatho yaseYurophu (EN)

Imiqadi ye-H eYurophu ilandela uthotho lwemigangatho yaseYurophu, efana ne-EN 10034 kunye ne-EN 10025, echaza iinkcukacha ezinobungakanani, iimfuno zemathiriyeli, iipropathi zoomatshini, umgangatho womphezulu kunye nemithetho yokuhlola ye-H-beams. Imiqadi eqhelekileyo yaseYurophu ye-H iquka i-HEA, HEB kunye ne-HEM series; uchungechunge lwe-HEA luqhele ukusetyenziswa ukumelana ne-axial kunye nemikhosi ethe nkqo, njengakwizakhiwo eziphakamileyo; uchungechunge lwe-HEB lufanelekile kwizakhiwo ezincinci ukuya kweziphakathi; kunye nochungechunge lwe-HEM lufanelekile kwizicelo ezifuna ukuyila ubunzima obulula ngenxa yobude obuncinci kunye nobunzima. Uluhlu ngalunye lufumaneka kwiindidi ezahlukeneyo zobukhulu.
Uchungechunge lwe-HEA: HEA100, HEA120, HEA140, HEA160, HEA180, HEA200, njl.
HEB Series: HEB100, HEB120, HEB140, HEB160, HEB180, HEB200, njl.
Uchungechunge lwe-HEM: HEM100, HEM120, HEM140, HEM160, HEM180, HEM200, njl.

Umqadi we-American Standard H(ASTM/AISC)

I-American Society for Testing and Materials (ASTM) iphuhlise imigangatho ecacileyo ye-H-beams, njenge-ASTM A6 / A6M. Imifuziselo ye-American Standard H-beam idla ngokubonakaliswa ngefomathi yeWx okanye yeWXxxy, umz., W8 x 24, apho u-“8” ubhekisa kububanzi beflange ngee-intshi kwaye “24” ichaza ubunzima ngenyawo nganye yobude (iiponti). Ukongeza, kukho W8 x 18, W10 x 33, W12 x 50, njl. njl.reI-ASTM A36, A572, njl.

Umgangatho waseBritane (BS)

I-H-beams phantsi koMgangatho waseBrithani ilandela iinkcukacha ezifana ne-BS 4-1: 2005 + A2: 2013. Iindidi ziquka i-HEA, i-HEB, i-HEM, i-HN kunye nabanye abaninzi, kunye nochungechunge lwe-HN lubeka ugxininiso oluthile kumandla okumelana nemikhosi ethe tye kunye nethe nkqo. Inombolo yomzekelo ngamnye ilandelwa linani ukubonisa imilinganiselo yobungakanani obuthile, umz. HN200 x 100 ibonisa imodeli enobude nobubanzi obuthile.

Umgangatho woShishino lwaseJapan (JIS)

UmGangatho woShishino lwaseJapan (JIS) we-H-beams ikakhulu ubhekisa kumgangatho we-JIS G 3192, oqulathe amabanga amaninzi afana nala.SS400, I-SM490, njl njl. I-SS400 yintsimbi yesakhiwo esiqhelekileyo esifanelekileyo kwimisebenzi yokwakha ngokubanzi, ngelixa i-SM490 inika amandla aphezulu kwaye ifanelekile kwizicelo ezinzima. Iindidi zibonakaliswa ngendlela efanayo njengaseTshayina, umz. H200×200, H300×300, njl njl. Ubukhulu obunjengobude kunye nobubanzi beflange bubonisiwe.

Imigangatho yoShishino lwaseJamani (DIN)

Ukuveliswa kwee-H-beams eJamani kusekelwe kwimigangatho efana ne-DIN 1025, umzekelo uchungechunge lwe-IPBL. Le migangatho iqinisekisa umgangatho kunye nokuhambelana kweemveliso kwaye ifanelekile kuluhlu olubanzi lwezicelo zoshishino.

Ostreliya
Imigangatho: AS/NZS 1594 njl.
Iimodeli: umz. 100UC14.8, 150UB14, 150UB18, 150UC23.4, njl.

Ukushwankathela, nangona imigangatho kunye neentlobo ze-H-beams zihluka ukusuka kwilizwe ukuya kwilizwe kunye nommandla ukuya kummandla, babelana nenjongo efanayo yokuqinisekisa umgangatho wemveliso kunye nokuhlangabezana neemfuno zobunjineli ezahlukeneyo. Enyanisweni, xa ukhetha i-H-beam efanelekileyo, kuyimfuneko ukuqwalasela iimfuno ezithile zeprojekthi, iimeko zokusingqongileyo kunye nezithintelo zebhajethi, kunye nokuthobela iikhowudi zokwakha zendawo kunye nemigangatho. Ukhuseleko, ukuqina kunye noqoqosho lwezakhiwo lunokuphuculwa ngokufanelekileyo ngokukhethwa kwengqiqo kunye nokusetyenziswa kwe-H-beams.
