Amahame n'Ingero z'imirasire ya H mu bihugu bitandukanye

Umugozi wa H ni ubwoko bw'icyuma kirekire gifite igice cya H, cyitiriwe imiterere yacyo isa n'inyuguti y'Icyongereza "H". Gifite imbaraga nyinshi n'imiterere myiza ya mekanike, kandi gikoreshwa cyane mu bwubatsi, ibiraro, inganda n'ibindi bikorwa.

Ibipimo ngenderwaho by'Igihugu cy'Ubushinwa (GB)

Imirasire ya H mu Bushinwa ikorwa cyane cyane kandi igashyirwa mu byiciro bishingiye ku mirasire ya H ishyushye na T-beams (GB/T 11263-2017). Bitewe n'ubugari bwa flange, ishobora gushyirwa mu byiciro bya H-beam (HW), H-beam (HM) na H-beam (HN). Urugero, HW100×100 ihagarariye H-beam ifite ubugari bwa 100mm n'uburebure bwa 100mm; HM200×150 ihagarariye H-beam ifite ubugari bwa 200mm n'uburebure bwa 150mm. Byongeye kandi, hari ibyuma bikonje bifite inkuta nto n'ubundi bwoko bwihariye bwa H-beams.

Amabwiriza y'Uburayi (EN)

Imirasire ya H mu Burayi ikurikiza amahame ngenderwaho y’i Burayi, nka EN 10034 na EN 10025, asobanura neza imiterere y’ibipimo, ibisabwa mu bikoresho, imiterere ya mekanike, ubwiza bw’ubuso n’amategeko agenga igenzura ry’imirasire ya H. Imirasire ya H isanzwe ikoreshwa mu Burayi irimo HEA, HEB na HEM; urukurikirane rwa HEA rukoreshwa mu kwihanganira imbaraga z’imirongo n’izihagaze, nko mu nyubako ndende; urukurikirane rwa HEB rukwiriye inyubako nto kugeza ku ziciriritse; kandi urukurikirane rwa HEM rukwiriye gukoreshwa mu buryo busaba igishushanyo cyoroheje bitewe n’uburebure n’uburemere bwarwo buto. Buri rukurikirane ruboneka mu bunini butandukanye butandukanye.
Urukurikirane rwa HEA: HEA100, HEA120, HEA140, HEA160, HEA180, HEA200, n'ibindi.
Urukurikirane rwa HEB: HEB100, HEB120, HEB140, HEB160, HEB180, HEB200, n'ibindi.
Urukurikirane rwa HEM: HEM100, HEM120, HEM140, HEM160, HEM180, HEM200, n'ibindi.

Umuraba wa H usanzwe wo muri Amerika(ASTM/AISC)

Ishyirahamwe ry’Abanyamerika ryita ku bipimo n’ibikoresho (ASTM) ryashyizeho amahame arambuye ku mirasire ya H, nka ASTM A6/A6M. Imirasire ya H-beam isanzwe ya Amerika ikunze kugaragara mu buryo bwa Wx cyangwa WXxxy, urugero, W8 x 24, aho "8" yerekeza ku bugari bwa flange muri santimetero na "24" yerekeza ku buremere kuri buri metero y’uburebure (ibiro). Byongeye kandi, hari W8 x 18, W10 x 33, W12 x 50, nibindi. Ingufu zisanzwe akongeraASTM A36, A572, n'ibindi.

Ibipimo ngenderwaho by'Ubwongereza (BS)

Imirasire ya H-beams ikurikije British Standard ikurikiza amabwiriza nka BS 4-1:2005+A2:2013. Ubwoko burimo HEA, HEB, HEM, HN n'izindi nyinshi, aho HN series ishyira imbaraga cyane ku bushobozi bwo kwihanganira imbaraga zitambitse n'izihagaze. Buri nomero ya moderi ikurikirwa n'inomero kugira ngo igaragaze ibipimo by'ingano runaka, urugero: HN200 x 100 igaragaza moderi ifite uburebure n'ubugari bwihariye.

Ibipimo ngenderwaho by'inganda zo mu Buyapani (JIS)

Amabwiriza y'Ubuyapani y'inganda (JIS) yerekeye imirasire ya H yerekeza ahanini ku gipimo cya JIS G 3192, kirimo amanota menshi nkaSS400, SM490, nibindi. SS400 ni icyuma gisanzwe gikoreshwa mu bwubatsi rusange, mu gihe SM490 itanga imbaraga nyinshi zo gukurura kandi ikoreshwa mu mirimo ikomeye. Ubwoko bugaragazwa mu buryo bumwe n’ubwo mu Bushinwa, urugero: H200×200, H300×300, nibindi. Ingano nk’uburebure n’ubugari bw’urukiramende biragaragazwa.

Amabwiriza y'inganda yo mu Budage (DIN)

Ikorwa rya H-beams mu Budage rishingiye ku bipimo ngenderwaho nka DIN 1025, urugero nk'uruhererekane rwa IPBL. Aya mahame yemeza ireme n'ubuziranenge bw'ibicuruzwa kandi akwiriye gukoreshwa mu nganda zitandukanye.

Ositaraliya
Amabwiriza: AS/NZS 1594 n'ibindi.
Modeli: urugero: 100UC14.8, 150UB14, 150UB18, 150UC23.4, n'ibindi.

Muri make, nubwo amahame n'ubwoko bw'imitako ya H-beams bitandukanye bitewe n'igihugu n'akarere, bihuriye ku ntego imwe yo kwemeza ireme ry'ibicuruzwa no guhaza ibyifuzo bitandukanye by'ubuhanga. Mu by'ukuri, mu gihe uhitamo imitako ya H-beam ikwiye, ni ngombwa gusuzuma ibisabwa byihariye by'umushinga, imiterere y'ibidukikije n'ingengo y'imari, ndetse no kubahiriza amategeko n'amabwiriza y'inyubako zo mu gace utuyemo. Umutekano, kuramba n'ubukungu bw'inyubako bishobora kunozwa neza binyuze mu guhitamo no gukoresha imitako ya H-beams mu buryo bushyize mu gaciro.
