Menyekanisha uburyo bwagutse bwimbeho ikonje
Mu nyubako z’inganda n’imbonezamubano, beto ya fer yakoreshejwe imyaka myinshi
Inzira ndende hamwe n’umwanda mwinshi.Mumyaka yashize, hamwe nitsinzi ryashyushyeH-beamibicuruzwa bya Ma Steel na Lai Steel
Nk’uko byatangajwe ku isoko, ikoreshwa ry’ibyuma mu nganda zubaka ryagiye ryiyongera.Inyubako zinyuranye zubaka inyubako zigeragezwa, amazu yicyitegererezo ninyubako nyaburanga byamenyekanye kimwekindi.Ibipimo nibisobanuro byubushakashatsi nubwubatsi nabyo byatangiye kwinjira murwego rwo gutera imbere buhoro buhoro.Inganda zubaka ibyuma byubushinwa zateye intambwe nini mumyaka yashize.
Ariko, kuri ubu, inyubako zubatswe n’Ubushinwa zikoreshwa cyane cyane mu byuma bishyushye bya H bisa n’ibyuma bitandukanye.Ubushobozi bw'icyuma gishyushye H gifite ishusho ya H mu Bushinwa bugeze kuri toni miliyoni 3, kandi umusaruro w’icyuma cyasuditswe n’icyuma cya H hamwe n’ibyuma bitandukanye na byo ni toni ibihumbi magana.Umusaruro w'imiyoboro isudira mu Bushinwa urenga toni miliyoni 7 ku mwaka, muri zo umusaruro waimbeho ikonje kandi ifite urukiramendenuburyo butandukanye bwubukonje bwubatswe bwubaka ibyuma biri munsi ya 5% yumusaruro wose wibyuma bikonje.Ikoreshwa ryibyuma bikonje mu nganda n’ubwubatsi bw’ubwubatsi mu Bushinwa biri mu ntangiriro.Imirongo ikonje ikonje hamwe nurukiramende rwubatswe rwasuditswe rwatangiye gusimbuza ibyuma bishyushye H-shusho nkicyuma cyubatswe.Ibindi byuma bikonje bikoreshwa cyane mubikorwa byubwubatsi.

Kugeza ubu, Minisiteri y’Ubwubatsi yubatse inyubako zipima ibyuma mu nyubako n’inganda n’imbonezamubano, nka
Amazu abiri yerekana imyubakire ya minisiteri yubwubatsi yubatswe muri Tianjin mu 2002. Imiyoboro yicyuma yakoreshejwe muri uyu mushinga
Inkingi ya beto ibyuma bikozwe mubyuma bishimangira ibyuma byubatswe (SRC) sisitemu yimiterere, ubuso bwumushinga wose
8000m2, umubiri nyamukuru ufite igorofa cumi nimwe, inkingi imwe ikozwe mu muyoboro uzengurutse, indi nkingi ikozwe mu cyuma cya kare
350x350mm, ubunini buratandukana hasi, muri yo igorofa ya 1 ~ 3 ni 16mm, 4 ~
14mm kuri etage ya 6, 12mm kuri etage ya 7 kugeza 9, 10mm kuri etage ya 10 kugeza 11, hanyuma isukwa mumiyoboro yicyuma
C40 beto.
Igiti gikozwe mu gusudira I-beam hamwe na 350x200x10x18mm, hamwe na plaque hasi
Nibisate byubahwa hamwe nibisumizi byimbaraga zikomeye zizenguruka imbavu.Muri kiriya gihe, nta muhinguzi wo mu Bushinwa wigeze akora umuyoboro wa kare ufite umurambararo munini cyane, bityo ibyuma bikoresha ibyuma bya kare byakoreshwaga muri uwo mushinga, wasangaga amasahani ane asudira inkingi za BOX.
Umushinga werekana imyubakire yimyubakire ya minisiteri yubwubatsi ya Tianjin Yuantai Derun Steel Pipe Manufacturing Group Co., Ltd ikuramo ibintu bibiri bivuye mugukoresha ibyuma byubatswe bikonje (cyane cyane umuyoboro urukiramende) mumazu yubatswe:
Ubwa mbere, umwanya wamasoko yubunini bunini bukonje bwubatswe nurukiramende ni runini, kandi umubare wuzuye wa etage yo kubaka ibyuma ni
Hamwe na etage 10 ~ 18, izo nyubako zo hagati no hejuru zirazamuka nazo zifite ibisabwa bimwe mubisobanuro byerekana imiyoboro ikonje ikonje.
Icya kabiri, imiyoboro ya kwadarato ifite ibyiza bigaragara hejuru yicyuma kizunguruka kubwimpamvu eshatu:
Ubwa mbere, kare na ruziga rufite uburebure bumwe na diametre bifite ubushobozi bwo gutwara no gukora imitingito
Nibyiza.Ukurikije ikizamini cyakozwe na kaminuza yo muri Tianjin ku magorofa atatu ya metero kare ebyiri zingana na tariyeri izenguruka
Uburebure bw'uruhande rw'imiyoboro ni 150mm, na diameter y'umuyoboro uzengurutse ni 150mm.Ibisubizo by'ibizamini byerekana ko ibyambere birwanya imbaraga zitanga umusaruro
Ubushobozi bwo kwikorera hamwe nubushobozi bwo gutwara ibintu burenze 80% kurenza ibya nyuma, naho icyerekezo cyibiza ni hafi kabiri cyanyuma;
Icya kabiri, kubaka imiyoboro ya kare iroroshye.Inkingi ifatika yimiterere yicyuma igomba kuba imbere
Kubwubatsi, igice kizengurutswe gihinduka igice cya kare;
Icya gatatu, biragoye guhangana nisano iri hagati yizenguruko ya beto ninkingi.Imiterere yicyuma kizaza mubushinwa
Ku isoko, imiyoboro ikonje ikonje hamwe nuyoboro urukiramende bizagira umugabane wingenzi.
Ubushyuhe bwo hejuru bwo gutunganya ibyuma birashobora kuzamura cyane umunaniro wibikorwa byibicuruzwa.Kurugero, tekinoroji yumwimerere yo gutunganya ibinyabiziga igice cya axe ikozwe mubyuma nubuvuzi busanzwe, kandi ubuzima bwumurimo bwiyongereyeho inshuro zigera kuri 20 uhindura kuva mubushyuhe bwo hejuru ukajya kuvura ubushyuhe.Byongeye kandi, kuvura ubushyuhe bwo hejuru bigabanya imyanya yubusa yibice.Intego yo kuvura ubushyuhe bwo hejuru ni ukunoza neza ibiranga ibicuruzwa.Ikoreshwa cyane mubice bitandukanye, bifitanye isano ya hafi nibiranga byombi.
