Nigute wahitamo Umurabyo wa H ukwiye mu nganda z'ubwubatsi?

Mu nganda z'ubwubatsi,Imirasire ya Hzizwi nka "inkingi y'inyubako zitwara imizigo"—guhitamo kwazo mu buryo bufatika bigena mu buryo butaziguye umutekano, kuramba, no kugabanya ikiguzi cy'imishinga. Bitewe no kwaguka gukomeye kw'inyubako z'ibikorwa remezo n'amasoko y'inyubako ndende, uburyo bwo guhitamo imirasire ya H ihuye n'ibikenewe mu mishinga itandukanye byabaye ikibazo cy'ingenzi ku bahanga mu by'imashini n'amatsinda ashinzwe gutanga amasoko. Hasi hari ubuyobozi burambuye bwibanda ku miterere y'ingenzi, imiterere yihariye, n'ikoreshwa ry'imirasire ya H kugira ngo bifashe abakinnyi mu nganda gufata ibyemezo bya siyansi.

Tangira n'Ibiranga by'Ingenzi: Fata "Amahame Ngenderwaho" ya H Beams

Guhitamo imirasire ya H bigomba kubanza gushingira ku bintu bitatu by'ingenzi bitavugwaho rumwe, kuko bifitanye isano itaziguye no kumenya niba ibicuruzwa bishobora kuzuza ibisabwa mu miterere y'inyubako.

Icyiciro cy'ibikoresho： Ibikoresho bikunze gukoreshwa mu gukora imirasire ya H ni icyuma cyubatswe na karuboni (nk'Q235B, Q355B H Beammu bipimo ngenderwaho by'Abashinwa, cyangwaUmuringa wa A36, A572 Hmu bipimo bya Amerika) n'icyuma gikomeye cyane gikozwe mu buryo budakoresha aloyi nke. Umurimbo wa Q235B/A36 H ukwiriye imirimo yo kubaka imitungo rusange (urugero, inyubako zo guturamo, inganda nto) bitewe nuko ubasha gusudira neza kandi ugahenda; Q355B/A572, ifite imbaraga nyinshi zo gutanga umusaruro (≥355MPa) n'imbaraga zo gukurura, ikundwa cyane mu mishinga ikomeye nk'ibiraro, amaduka manini, n'inyubako ndende, kuko ishobora kugabanya ingano y'umurimbo no kuzigama umwanya.

Ibisobanuro by'ingano: Imirasire ya H igenwa n'ibipimo bitatu by'ingenzi: uburebure (H), ubugari (B), n'ubugari bw'urubuga (d). Urugero, umurasire wa H wanditseho "H300×150×6×8"bivuze ko ifite uburebure bwa mm 300, ubugari bwa mm 150, ubugari bwa web bwa mm 6, n'ubugari bwa mm 8. Imitako mito ya H (H≤200mm) ikunze gukoreshwa ku nyubako z'inyongera nko ku nkuta zo hasi n'inkunga zo gutandukanya; imitako iringaniye (200mm＜H＜400mm) ishyirwa ku nkuta z'inyubako z'amagorofa menshi n'ibisenge by'inganda; imitako minini ya H (H≥400mm) ni ingenzi cyane ku nyubako ndende cyane, ibiraro birebire, n'ibikoresho by'inganda.

Imikorere ya tekiniki: Ibande ku bimenyetso nk'imbaraga z'umusaruro, imbaraga zo gukurura, n'ubukomere bw'ingaruka. Ku mishinga yo mu turere dukonje (urugero, mu majyaruguru y'Ubushinwa, muri Kanada), imirasire ya H igomba gutsinda ibizamini by'ingaruka z'ubushyuhe buri hasi (nk'ubukomere bw'ingaruka -40℃ ≥34J) kugira ngo hirindwe kuvunika nabi mu bihe by'ubukonje; ku bice by'imitingito, ibicuruzwa bifite ubushobozi bwo kugenda neza (uburebure ≥20%) bigomba gutoranywa kugira ngo byongere ubushobozi bwo kurwanya imitingito.

Koresha Ibiranga Bidasanzwe: Huza "Ibyiza by'Ibicuruzwa" n'Ibikenewe mu Mushinga

Ugereranyije n'ibice by'icyuma bisanzwe nkaImirasire ya In'ibyuma bikoresha imiyoboro, imiyoboro ya H ifite imiterere yihariye ituma ikwiriye imiterere yihariye y'ubwubatsi—gusobanukirwa izi nyungu ni ingenzi mu guhitamo ibintu byihariye.

Ingufu nyinshi zo gutwara imizigo: Igice cy’imiringa ya H gifite ishusho ya H gikwirakwiza ibikoresho mu buryo bushyize mu gaciro: imiringa ikomeye (ibice byo hejuru n’ibyo hasi bitambitse) ifite umwanya munini wo kunama, mu gihe urushundura rworoshye (igice cyo hagati gihagaze) rurwanya imbaraga zo gukata. Iyi miterere yemerera imiringa ya H kugera ku bushobozi bwo gutwara imizigo bwinshi hamwe n’icyuma gito gikoreshwa—ugereranije n’imiringa ya I ifite uburemere bumwe, imiringa ya H ifite imbaraga zo kunama ziri hejuru ya 15%-20%. Iyi miterere ituma iba myiza ku mishinga ikurikirana kuzigama amafaranga n’inyubako zoroshye, nko mu nyubako zakozwe mbere no mu bwubatsi bwa modular.

Ihamye kandi yoroshye kuyishyiraho: Igice cya H gihuza ibice bingana bigabanya imiterere y’umugongo mu gihe cyo kubaka, bigatuma imirasire ya H ikomera iyo ikoreshejwe nk'imirasire ikomeye itwara imizigo. Byongeye kandi, imirasire yabo irambuye yoroshye kuyihuza n'ibindi bice (urugero: bolts, welds) nta gutunganya ibintu bigoye—ibi bigabanya igihe cyo kubaka ahantu ho kubaka ho ku kigero cya 30% ugereranije n'ibice by'icyuma bidakora neza, ibi bikaba ari ingenzi ku mishinga yihuta nk'amazu y'ubucuruzi n'ibikorwa remezo byihutirwa.

Kurwanya ingese no kurwanya inkongi y'umuriro (hamwe n'uburyo bwo kuyivura): Imirasire ya H idatunganyijwe ikunze kwangirika, ariko nyuma yo gusukura hejuru nko gukoresha galvanizing ishyushye cyangwa epoxy coating, ishobora kurwanya ingese mu bidukikije bikonje cyangwa ku nkombe (urugero, ku mbuga, ku mihanda yo ku nkombe). Ku bijyanye n'ubushyuhe bwinshi nko mu nganda zikora amatanura, imirasire ya H idashya (isizwe irangi ririnda umuriro) ishobora kugumana ubushobozi bwo gutwara imizigo mu gihe cy'iminota irenga 120 mu gihe habayeho inkongi, byujuje ibisabwa bikomeye mu kurinda inkongi.

Ingero z'Ishyirwa mu Bikorwa ry'Intego: Amahitamo Akwiye

Imishinga itandukanye y'ubwubatsi ifite ibisabwa bitandukanye kuri H-beams. Guhuza imiterere y'ibicuruzwa n'ibisabwa aho bikenewe ni byo byonyine bishobora kongerwa agaciro kabyo. Ibi bikurikira ni ibihe bitatu bisanzwe byo gukoreshwa n'ibisabwa kuvanga.

Inyubako zo guturamo n'iz'ubucuruzi ndende: Ku nyubako zifite amagorofa 10-30, imitako ya H-gauge iciriritse ikozwe mu cyuma cya Q355B (H250 × 125 × 6 × 9 kugeza H350 × 175 × 7 × 11) irasabwa. Ingufu zazo nyinshi zishyigikira uburemere bw'amagorofa menshi, mu gihe ingano yazo nto izigama umwanya wo gushushanya imbere.

Ibiraro n'inyubako ndende: Ibiraro birebire (uburebure bwa metero ≥50) cyangwa ibisenge bya sitade bisaba imirasire minini kandi ikomeye cyane ya H-beams (H400×200×8×13 cyangwa irenga).

Inganda n'ububiko bw'inganda: Inganda zikora ibintu bikomeye (nk'inganda zikora imodoka) n'ububiko bunini bisaba imirasire ya H ishobora gutwara uburemere bw'ibikoresho cyangwa imitwaro ipakiye.
