Imirasire ya H ikurikije amahame y’i Burayi ishyirwa mu byiciro hakurikijwe imiterere yayo, ingano n’imiterere ya mekanike. Muri uru ruhererekane, HEA na HEB ni ubwoko bubiri busanzwe, buri bumwe bufite uburyo bwihariye bwo kubukoresha. Hasi hari ibisobanuro birambuye kuri ubu buryo bubiri, harimo itandukaniro ryabwo n’uburyo bukoreshwa.
HEAUrukurikirane
Uruhererekane rwa HEA ni ubwoko bw'icyuma cya H-beam gifite imigozi mito ikwiriye inyubako zisaba inkunga yo ku rwego rwo hejuru. Ubu bwoko bw'icyuma bukunze gukoreshwa mu nyubako ndende, ibiraro, imiyoboro y'amazi, n'ibindi bikorwa by'ubuhanga. Igishushanyo mbonera cy'igice cya HEA kirangwa n'uburebure bw'igice kinini n'urushundura rworoshye, bituma kiba indashyikirwa mu kwihanganira ibihe binini byo kugonda.
Imiterere y'igice: Imiterere y'igice cy'uruhererekane rwa HEA igaragaza ishusho isanzwe ya H, ariko ifite ubugari buto bw'urukiramende.
Ingano: Uduce duto duto ni twagutse ariko uduce duto duto, kandi uburebure busanzwe buri hagati ya mm 100 na mm 1000, urugero, ingano ya HEA100 ni hafi mm 96 × 100 × 5.0 × 8.0 (uburebure × ubugari × ubugari bwa web × ubunini bwa flange).
Uburemere bwa metero (uburemere kuri metero): Uko umubare w’icyitegererezo wiyongera, uburemere bwa metero nabwo buriyongera. Urugero, HEA100 ifite uburemere bwa metero bugera kuri 16.7 KG, mu gihe HEA1000 ifite uburemere bwa metero burebure cyane.
Ingufu: Ingufu nyinshi n'ubukana, ariko ubushobozi bwo gutwara imizigo buke ugereranije n'uburyo bwa HEB.
Ubudahangarwa: Uduce duto cyane n'ubugari bw'inzu usanga ari duto cyane mu bijyanye no kudahungabana iyo duhuye n'igitutu n'igihe cyo gupfunyika, nubwo dushobora kuzuza ibisabwa byinshi mu miterere y'igishushanyo mbonera gikwiye.
Ubudahangarwa bwo gushyushya: Ubudahangarwa bwo gushyushya ni buke kandi bukwiriye inyubako zidasaba imbaraga nyinshi zo gushyushya.
Imikoreshereze: Bitewe n'uburebure bwayo bunini bw'igice n'imbaraga nziza zo kunama, ibice bya HEA bikunze gukoreshwa aho umwanya ari ingenzi cyane, nko mu nyubako ndende z'inyubako ndende.
Igiciro cyo gukora: Ibikoresho bikoreshwa ni bike, uburyo bwo gukora biroroshye, kandi ibisabwa ku bikoresho byo gukora ni bike, bityo ikiguzi cyo gukora ni gito.
Igiciro cy'Isoko: Ku isoko, ku burebure n'ingano bimwe, igiciro kiba kiri hasi ugereranije n'uruhererekane rwa HEB, rufite inyungu ku giciro kandi rukwiriye imishinga ihenze.
HEBUrukurikirane
Ku rundi ruhande, uruhererekane rwa HEB ni umurambararo wa H-beam munini, ufite ubushobozi bwo gutwara imizigo bwinshi ugereranije na HEA. Ubwo bwoko bw'icyuma bukwiriye cyane cyane inyubako nini, ibiraro, iminara, n'ibindi bikorwa aho imizigo minini igomba gutwarwa.
Imiterere y'Igice: Nubwo HEB nayo ifite imiterere imwe ya H, ifite ubugari bwa flange bunini kurusha HEA, butanga ubushobozi bwo gutuza no gutwara imizigo neza.
Ingano: flange ni nini kandi uruziga rurakomeye, uburebure nabwo buri hagati ya mm 100 na mm 1000, nk'uko HEB100 ibivuga ni hafi mm 100 × 100 × 6 × 10, bitewe n'ubugari bw'urukiramende, ubuso bw'igice n'uburemere bwa metero bya HEB bizaba binini kuruta ubw'icyitegererezo cya HEA gihuye nacyo munsi y'umubare umwe.
Uburemere bwa metero: Urugero, uburemere bwa metero ya HEB100 ni hafi 20.4KG, ni ukwiyongera ugereranije na 16.7KG bya HEA100; iri tandukaniro rirushaho kugaragara uko umubare w'icyitegererezo wiyongera.
Ingufu: Bitewe n'uko ifite flange nini n'ubugari bw'urukuta, ifite imbaraga zo gukurura, aho igera n'imbaraga zo gukata, kandi ishobora kwihanganira kunama, gukata no gukata cyane.
Gutuza: Iyo ishyizwe mu biremereye byinshi n'imbaraga zo hanze, igaragaza gutuza neza kandi ntishobora guhindagurika cyangwa kudatuza.
Imikorere ya Torsional: flange nini n'ubugari bw'urukuta bituma iba nziza mu mikorere ya torsional, kandi ishobora kurwanya neza imbaraga za torsional zishobora kubaho mu gihe cyo gukoresha inyubako.
Imikoreshereze: Bitewe n'uko ifite imigozi minini kandi ikaba minini, ibice bya HEB ni byiza cyane mu mikoreshereze aho bisaba inkunga n'ubudahangarwa byiyongera, nko kubaka ibikorwa remezo by'imashini ziremereye cyangwa kubaka ibiraro binini.
Ikiguzi cyo gukora: Hakenewe ibikoresho fatizo byinshi, kandi inzira yo gukora isaba ibikoresho n'imikorere myinshi, nko gukaza umuvuduko mwinshi no kugenzura neza mu gihe cyo gukora, bigatuma ikiguzi cyo gukora kiriyongera.
Igiciro cy'isoko: Ibiciro byo hejuru by'umusaruro bitera igiciro kiri hejuru ku isoko, ariko mu mishinga isabwa imikorere myiza, igipimo cy'igiciro/imikorere kiracyari hejuru cyane.
Igereranya ryuzuye
Mu gihe uhisemo hagatiHea / Heb, ikintu cy'ingenzi kiri mu byo umushinga runaka ukeneye. Niba umushinga ukeneye ibikoresho bifite ubushobozi bwo kunama neza kandi bitagizweho ingaruka zikomeye n'umwanya muto, HEA ishobora kuba amahitamo meza. Ku rundi ruhande, niba intego y'umushinga ari ugutanga ubushobozi bukomeye bwo guhagarara no kudahungabana, cyane cyane iyo hari imitwaro myinshi, HEB yaba ikwiriye kurushaho.
Ni ngombwa kandi kumenya ko hashobora kubaho itandukaniro rito hagati y’imiterere ya HEA na HEB ikorwa n’inganda zitandukanye, bityo ni ngombwa gusuzuma neza ibipimo bireba kugira ngo harebwe ko byujuje ibisabwa mu gihe cyo kugura no gukoresha. Muri icyo gihe, ubwoko ubwo aribwo bwose bwatoranyijwe, hagomba kugenzurwa ko icyuma cyatoranijwe cyujuje ibikubiye mu mahame ngenderwaho y’i Burayi nka EN 10034 kandi ko cyatsinze icyemezo cy’ubuziranenge. Izi ngamba zifasha kwemeza umutekano n’ubwizerwe bw’inyubako ya nyuma.
