Miyezo ndi Zitsanzo za matabwa a H M'mayiko Osiyanasiyana

H-beam ndi mtundu wachitsulo chachitali chokhala ndi gawo lofanana ndi H, lomwe limatchedwa chifukwa mawonekedwe ake amafanana ndi chilembo cha Chingerezi "H". Lili ndi mphamvu zambiri komanso makina abwino, ndipo amagwiritsidwa ntchito kwambiri pomanga, mlatho, kupanga makina ndi zina.

Chinese National Standard (GB)

H-matabwa ku China amapangidwa makamaka ndi m'magulu kutengera Hot adagulung'undisa H-matabwa ndi Sectional T-matabwa (GB/T 11263-2017). Kutengera m'lifupi mwa flange, imatha kugawidwa m'magulu amtundu wa H-mtengo (HW), sing'anga-flange H-mtengo (HM) ndi yopapatiza-flange H-mtengo (HN). Mwachitsanzo, HW100 × 100 amaimira lonse flange H-mtengo ndi flange m'lifupi mwake 100mm ndi kutalika kwa 100mm; HM200 × 150 imayimira sing'anga flange H-mtengo ndi flange m'lifupi mwake 200mm ndi kutalika kwa 150mm. Kuonjezera apo, pali zitsulo zozizira zokhala ndi mipanda yopyapyala ndi mitundu ina yapadera ya matabwa a H.

Miyezo yaku Europe (EN)

Miyezo ya H ku Europe imatsata miyeso ingapo yaku Europe, monga EN 10034 ndi EN 10025, yomwe imafotokoza mwatsatanetsatane mawonekedwe, zofunikira zakuthupi, makina amakina, mawonekedwe apamwamba komanso malamulo oyendera ma H-mitengo. Mitundu yodziwika bwino ya ku Europe ya H-mitengo imaphatikizapo HEA, HEB ndi HEM mndandanda; mndandanda wa HEA umagwiritsidwa ntchito kulimbana ndi mphamvu za axial ndi zowongoka, monga m'nyumba zazitali; mndandanda wa HEB ndi woyenera kumagulu ang'onoang'ono mpaka apakatikati; ndipo mndandanda wa HEM umagwirizana ndi ntchito zomwe zimafuna mapangidwe olemera kwambiri chifukwa cha kutalika kwake ndi kulemera kwake. Mndandanda uliwonse umapezeka mumitundu yosiyanasiyana.
HEA Series: HEA100, HEA120, HEA140, HEA160, HEA180, HEA200, etc.
HEB Series: HEB100, HEB120, HEB140, HEB160, HEB180, HEB200, etc.
HEM Series: HEM100, HEM120, HEM140, HEM160, HEM180, HEM200, etc.

American Standard H mtengo(ASTM/AISC)

Bungwe la American Society for Testing and Equipment (ASTM) lapanga miyezo yatsatanetsatane ya matabwa a H, monga ASTM A6/A6M. Mitundu ya mitengo ya American Standard H-beam nthawi zambiri imawonetsedwa mumtundu wa Wx kapena WXxxy, mwachitsanzo, W8 x 24, pomwe "8" imatanthawuza m'lifupi mwake mwa mainchesi ndipo "24" imatanthawuza kulemera kwa phazi lililonse la utali (mapaundi). Kuphatikiza apo, pali W8 x 18, W10 x 33, W12 x 50, ndi zina.reChithunzi cha ASTM A36A572 ndi ena.

British Standard (BS)

Ma H-beams pansi pa British Standard amatsatira zodziwika bwino monga BS 4-1:2005+A2:2013. Mitunduyi ikuphatikiza HEA, HEB, HEM, HN ndi ena ambiri, ndi mndandanda wa HN womwe umatsindika kwambiri kuthekera kopirira mphamvu zopingasa komanso zoyima. Nambala iliyonse yachitsanzo imatsatiridwa ndi nambala yosonyeza kukula kwake, mwachitsanzo, HN200 x 100 imasonyeza chitsanzo chokhala ndi kutalika kwake ndi m'lifupi mwake.

Japanese Industrial Standard (JIS)

The Japanese Industrial Standard (JIS) kwa H-mitengo makamaka amatanthauza JIS G 3192 muyezo, amene ali giredi angapo mongaChithunzi cha SS400, SM490, etc. SS400 ndi wamba structural zitsulo zoyenera ntchito yomanga wamba, pamene SM490 amapereka mphamvu kumakoka apamwamba ndipo ndi oyenera ntchito zolemetsa-ntchito. Mitundu imasonyezedwa mofanana ndi ku China, mwachitsanzo, H200×200, H300×300, ndi zina zotero.

German Industrial Standards (DIN)

Kupanga kwa matabwa a H ku Germany kumatengera miyezo monga DIN 1025, mwachitsanzo mndandanda wa IPBL. Miyezo iyi imatsimikizira kuti zinthu zili bwino komanso zimakhazikika ndipo ndizoyenera kugwiritsa ntchito mafakitale osiyanasiyana.

Australia
Miyezo: AS/NZS 1594 etc.
Zitsanzo: mwachitsanzo 100UC14.8, 150UB14, 150UB18, 150UC23.4, etc.

Mwachidule, ngakhale kuti miyezo ndi mitundu ya matabwa a H imasiyanasiyana kumayiko ndi dera ndi dera, amagawana cholinga chimodzi chowonetsetsa kuti zinthu zili bwino komanso kukwaniritsa zosowa zosiyanasiyana zamainjiniya. M'zochita, posankha bwino H-mtengo, m'pofunika kuganizira zofunikira zenizeni za polojekitiyi, zochitika zachilengedwe ndi zovuta za bajeti, komanso kutsatira malamulo omanga nyumba ndi miyezo. Chitetezo, kulimba ndi chuma cha nyumba zitha kupitilizidwa bwino posankha mwanzeru komanso kugwiritsa ntchito matabwa a H.
