Imigangatho kunye neeModeli ze-H-beams kumazwe ahlukeneyo

I-H-beam luhlobo lwentsimbi ende ene-cross-section efana ne-H, ebizwa ngokuba yiyo ngenxa yokuba imo yayo yesakhiwo ifana nonobumba wesiNgesi othi “H”. Inamandla aphezulu kwaye ineempawu ezintle zoomatshini, kwaye isetyenziswa kakhulu ekwakheni, kwiibhulorho, kwimveliso yoomatshini nakwezinye iindawo.

Umgangatho weSizwe waseTshayina (GB)

Ii-H-beams eTshayina ziveliswa kwaye zahlulwe ngokwee-Hot Rolled H-beams kunye nee-Sectional T-beams (GB/T 11263-2017). Ngokuxhomekeke kububanzi beflegi, ingahlulwe ngokwee-wide-flange H-beam (HW), medium-flange H-beam (HM) kunye ne-narrow-flange H-beam (HN). Umzekelo, i-HW100×100 imele i-wide flange H-beam enobubanzi beflegi obuyi-100mm kunye nokuphakama kwe-100mm; i-HM200×150 imele i-medium flange H-beam enobubanzi beflegi obuyi-200mm kunye nokuphakama kwe-150mm. Ukongeza, kukho intsimbi encinci eyenziwe ngodonga olubandayo kunye nezinye iintlobo ezikhethekileyo ze-H-beams.

Imigangatho yaseYurophu (EN)

Ii-H-beams eYurophu zilandela uthotho lwemigangatho yaseYurophu, efana ne-EN 10034 kunye ne-EN 10025, ezichaza iinkcukacha zobukhulu, iimfuno zezinto eziphathekayo, iimpawu zoomatshini, umgangatho womphezulu kunye nemithetho yokuhlolwa kwee-H-beams. Ii-H-beams eziqhelekileyo zaseYurophu ziquka uthotho lwe-HEA, HEB kunye ne-HEM; uthotho lwe-HEA ludla ngokusetyenziselwa ukumelana namandla axial kunye nathe nkqo, njengakwizakhiwo eziphakamileyo; uthotho lwe-HEB lufanelekile kwizakhiwo ezincinci ukuya kweziphakathi; kwaye uthotho lwe-HEM lufanelekile kwizicelo ezifuna uyilo olulula ngenxa yokuphakama nobunzima balo obuncinci. Uthotho ngalunye lufumaneka kwiindidi ezahlukeneyo zobukhulu.
Uthotho lwe-HEA: HEA100, HEA120, HEA140, HEA160, HEA180, HEA200, njl.
Uthotho lwe-HEB: HEB100, HEB120, HEB140, HEB160, HEB180, HEB200, njl.
Uthotho lwe-HEM: HEM100, HEM120, HEM140, HEM160, HEM180, HEM200, njl.

Umqadi we-H oqhelekileyo waseMelika(ASTM/AISC)

I-American Society for Testing and Materials (ASTM) iphuhlise imigangatho eneenkcukacha ze-H-beams, njenge-ASTM A6/A6M. Iimodeli ze-American Standard H-beam zihlala zibonakaliswa kwifomathi ye-Wx okanye ye-WXxxy, umz., i-W8 x 24, apho u-“8” ebhekisa kububanzi beflegi ngee-intshi kwaye u-“24” umele ubunzima ngenyawo nganye yobude (iiponti). Ukongeza, kukho i-W8 x 18, i-W10 x 33, i-W12 x 50, njl. Amanqanaba aqhelekileyo amandla akwakhonaI-ASTM A36, A572, njl.

Umgangatho waseBritane (BS)

Ii-H-beams phantsi kweBritish Standard zilandela iinkcukacha ezifana ne-BS 4-1:2005+A2:2013. Ezi ntlobo ziquka i-HEA, i-HEB, i-HEM, i-HN kunye nezinye ezininzi, apho uthotho lwe-HN lugxininisa ngakumbi kumandla okumelana namandla athe tye nathe nkqo. Inombolo nganye yemodeli ilandelwa linani ukubonisa ubungakanani obuthile, umz. i-HN200 x 100 ibonisa imodeli enobude nobubanzi obuthile.

Umgangatho wezoShishino waseJapan (i-JIS)

I-Japanese Industrial Standard (JIS) yee-H-beams ibhekisa kakhulu kumgangatho we-JIS G 3192, oqulethe amanqanaba aliqela afanaSS400, SM490, njl. I-SS400 yintsimbi yesakhiwo eqhelekileyo efanelekileyo kwimisebenzi yokwakha ngokubanzi, ngelixa i-SM490 inika amandla aphezulu okutsalwa kwaye ifanelekile kwizicelo ezinzima. Iintlobo zibonakaliswa ngendlela efanayo neyaseTshayina, umz. i-H200×200, i-H300×300, njl. Ubukhulu obufana nokuphakama kunye nobubanzi beflegi buyaboniswa.

Imigangatho yoShishino yaseJamani (i-DIN)

Ukuveliswa kwee-H-beams eJamani kusekelwe kwimigangatho efana ne-DIN 1025, umzekelo uthotho lwe-IPBL. Le migangatho iqinisekisa umgangatho kunye nokuhambelana kweemveliso kwaye ifanelekile kwiintlobo ngeentlobo zezicelo zoshishino.

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

Ngamafutshane, nangona imigangatho kunye neentlobo ze-H-beams zahlukile kwilizwe ngalinye nakwimimandla ngemimandla, zabelana ngeenjongo ezifanayo zokuqinisekisa umgangatho wemveliso kunye nokuhlangabezana neemfuno ezahlukeneyo zobunjineli. Enyanisweni, xa ukhetha i-H-beam efanelekileyo, kuyimfuneko ukuqwalasela iimfuno ezithile zeprojekthi, iimeko zokusingqongileyo kunye nemida yebhajethi, kunye nokuthobela imithetho kunye nemigangatho yokwakha yasekuhlaleni. Ukhuseleko, ukuqina kunye noqoqosho lwezakhiwo lunokuphuculwa ngempumelelo ngokukhetha nokusebenzisa ii-H-beams ngendlela efanelekileyo.
