Miyezo ndi Zitsanzo za H-beams m'Mayiko Osiyanasiyana

Mtengo wa H ndi mtundu wa chitsulo chachitali chokhala ndi gawo lozungulira looneka ngati H, lomwe latchedwa chifukwa mawonekedwe ake amafanana ndi chilembo cha Chingerezi "H". Lili ndi mphamvu zambiri komanso makhalidwe abwino a makina, ndipo limagwiritsidwa ntchito kwambiri pa zomangamanga, milatho, kupanga makina ndi madera ena.

Muyezo Wadziko Lonse Wachi China (GB)

Ma H-beams ku China amapangidwa makamaka ndikugawidwa m'magulu kutengera ma Hot Rolled H-beams ndi Sectional T-beams (GB/T 11263-2017). Kutengera ndi m'lifupi mwa flange, imatha kugawidwa m'magulu awiri: wide-flange H-beam (HW), medium-flange H-beam (HM) ndi narrow-flange H-beam (HN). Mwachitsanzo, HW100×100 imayimira wide flange H-beam yokhala ndi flange m'lifupi mwa 100mm ndi kutalika kwa 100mm; HM200×150 imayimira medium flange H-beam yokhala ndi flange m'lifupi mwa 200mm ndi kutalika kwa 150mm. Kuphatikiza apo, pali chitsulo choonda chopangidwa ndi makoma ozizira ndi mitundu ina yapadera ya ma H-beams.

Miyezo ya ku Ulaya (EN)

Ma H-beams ku Europe amatsatira miyezo yosiyanasiyana ya ku Europe, monga EN 10034 ndi EN 10025, yomwe imafotokoza mwatsatanetsatane zomwe zili muyeso, zofunikira pa zinthu, mawonekedwe a makina, mtundu wa pamwamba ndi malamulo owunikira ma H-beams. Ma H-beams wamba ku Europe amaphatikizapo HEA, HEB ndi HEM series; HEA series nthawi zambiri imagwiritsidwa ntchito kupirira mphamvu za axial ndi vertical, monga m'nyumba zazitali; HEB series ndi yoyenera nyumba zazing'ono mpaka zapakati; ndipo HEM series ndi yoyenera kugwiritsa ntchito zomwe zimafuna kapangidwe kopepuka chifukwa cha kutalika kwake kochepa komanso kulemera kwake. Mndandanda uliwonse umapezeka m'mitundu yosiyanasiyana.
Mndandanda wa HEA: HEA100, HEA120, HEA140, HEA160, HEA180, HEA200, ndi zina zotero.
Mndandanda wa HEB: HEB100, HEB120, HEB140, HEB160, HEB180, HEB200, ndi zina zotero.
Mndandanda wa HEM: HEM100, HEM120, HEM140, HEM160, HEM180, HEM200, ndi zina zotero.

Mzere wa H wa ku America Standard(ASTM/AISC)

Bungwe la American Society for Testing and Materials (ASTM) lapanga miyezo yatsatanetsatane ya ma H-beams, monga ASTM A6/A6M. Ma American Standard H-beam models nthawi zambiri amafotokozedwa mu Wx kapena WXxxy format, mwachitsanzo, W8 x 24, pomwe "8" imatanthauza m'lifupi mwa flange mu mainchesi ndipo "24" imatanthauza kulemera pa phazi lililonse la kutalika (mapaundi). Kuphatikiza apo, pali W8 x 18, W10 x 33, W12 x 50, ndi zina zotero. Ma common strength grades akachiwiriASTM A36, A572, ndi zina zotero.

Muyezo wa ku Britain (BS)

Ma H-beams pansi pa British Standard amatsatira zofunikira monga BS 4-1:2005+A2:2013. Mitunduyi ikuphatikizapo HEA, HEB, HEM, HN ndi zina zambiri, ndipo mndandanda wa HN umaika chidwi kwambiri pa kuthekera kopirira mphamvu zopingasa ndi zoyimirira. Nambala iliyonse ya chitsanzo imatsatiridwa ndi nambala yosonyeza magawo enieni a kukula, mwachitsanzo HN200 x 100 imasonyeza chitsanzo chokhala ndi kutalika ndi m'lifupi mwake.

Muyezo wa Zamalonda waku Japan (JIS)

Muyezo wa Zamalonda waku Japan (JIS) wa ma H-beams makamaka umatanthauza muyezo wa JIS G 3192, womwe uli ndi magiredi angapo mongaSS400, SM490, ndi zina zotero. SS400 ndi chitsulo chomangira chomwe chimagwiritsidwa ntchito pomanga nyumba zambiri, pomwe SM490 imapereka mphamvu yolimba kwambiri ndipo ingagwiritsidwe ntchito pa ntchito zolemera. Mitundu imafotokozedwa mofanana ndi ku China, mwachitsanzo H200×200, H300×300, ndi zina zotero. Miyeso monga kutalika ndi m'lifupi mwa flange imasonyezedwa.

Miyezo Yamakampani Yaku Germany (DIN)

Kupanga ma H-beams ku Germany kumadalira miyezo monga DIN 1025, mwachitsanzo mndandanda wa IPBL. Miyezo iyi imatsimikizira mtundu ndi kusinthasintha kwa zinthu ndipo ndi yoyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana.

Australia
Miyezo: AS/NZS 1594 etc.
Ma Modeli: mwachitsanzo 100UC14.8, 150UB14, 150UB18, 150UC23.4, ndi zina zotero.

Mwachidule, ngakhale miyezo ndi mitundu ya mipiringidzo ya H imasiyana malinga ndi dziko ndi dera, cholinga chawo ndi chimodzi chotsimikizira kuti zinthu zili bwino komanso kukwaniritsa zosowa zosiyanasiyana zauinjiniya. Mwachidule, posankha mipiringidzo yoyenera ya H, ndikofunikira kuganizira zofunikira za polojekitiyi, momwe chilengedwe chilili komanso zoletsa za bajeti, komanso kutsatira malamulo ndi miyezo ya zomangamanga zakomweko. Chitetezo, kulimba komanso ndalama zogwirira ntchito za nyumba zitha kukulitsidwa bwino kudzera mu kusankha ndi kugwiritsa ntchito mipiringidzo ya H.
