Ibipimo bishya byuma byuma byamanutse kandi bizashyirwa mubikorwa kumugaragaro mu mpera za Nzeri

Imiterere mishya yuburinganire bwigihugu kuri rebar rezo GB 1499.2-2024 "ibyuma bya beto ishimangirwa igice cya 2: ibyuma bishyushye byimbaho ​​byimbaho" bizashyirwa mubikorwa kumugaragaro ku ya 25 Nzeri 2024

Mugihe gito, ishyirwa mubikorwa ryurwego rushya rifite ingaruka zingaruka kubiciro byarebarumusaruro n’ubucuruzi, ariko mugihe kirekire birerekana ingengabitekerezo rusange iyobora politiki irangira kugirango ireme ryibicuruzwa byimbere mu gihugu no guteza imbere inganda zibyuma kugeza hagati no murwego rwo hejuru rwurwego rwinganda.
I. Impinduka nini muburyo bushya: kuzamura ireme no guhanga udushya
Ishyirwa mu bikorwa ry’ibipimo ngenderwaho bya GB 1499.2-2024 ryazanye impinduka nyinshi z’ingenzi, zigamije kuzamura ireme ry’ibicuruzwa bya rebar no guhuza ibipimo by’inyuma by’Ubushinwa bijyanye n’ibipimo mpuzamahanga. Ibikurikira nimpinduka enye zingenzi:

1.Ibipimo bishya bishimangira cyane imipaka yo kwihanganira uburemere bwa rebar. By'umwihariko, kwemererwa gutandukana kuri 6-12 mm ya diameter rebar ni ± 5.5%, mm 14-20 ni + 4.5%, na 22-50 mm ni + 3.5%. Ihinduka rizagira ingaruka ku buryo butaziguye ku musaruro wa rebar, bisaba ababikora kuzamura urwego rwibikorwa byubushobozi hamwe nubushobozi bwo kugenzura ubuziranenge.
2. Kubireba imbaraga-rebar amanota nkaHRB500E, HRBF600Ena HRB600, ibipimo bishya bitegeka gukoresha inzira yo gutunganya. Iki gisabwa kizazamura cyane ireme nibikorwa bihamye byimbaraga-zohejuruibyuma, no kurushaho guteza imbere inganda mu cyerekezo cyo guteza imbere ibyuma bikomeye.
3. Kubisobanuro byihariye byo gusaba, ibipimo bishya bitangiza imikorere yumunaniro. Ihinduka rizamura ubuzima bwa serivisi n'umutekano wa rebar munsi yumutwaro uremereye, cyane cyane kubiraro, inyubako ndende nindi mishinga ifite ibisabwa cyane kugirango imikorere yumunaniro.
4. Ivugurura risanzwe ryerekana uburyo bwo gutoranya hamwe nuburyo bwo kwipimisha, harimo kongeramo ikizamini cyo kugoreka inyuma ya rebar ya "E". Izi mpinduka zizamura ukuri no kwizerwa mugupima ubuziranenge, ariko birashobora kandi kongera ikiguzi cyibizamini kubabikora.
Icya kabiri, ingaruka kubiciro byumusaruro
Ishyirwa mu bikorwa ry’urwego rushya rizafasha umuyobozi w’ibigo bitanga umusaruro w’udodo kuzamura ireme ry’ibicuruzwa, kongera isoko ku isoko, ariko kandi bizana ibiciro by’umusaruro ukabije: nk'uko ubushakashatsi bubyerekana, umuyobozi w’inganda zikora ibyuma bijyanye n’urwego rushya ibiciro byibicuruzwa biziyongera hafi 20 yuan / toni.
Icya gatatu, ingaruka ku isoko

Ibipimo bishya bizateza imbere iterambere nogukoresha ibikoresho byibyuma bikomeye. Kurugero, 650 MPa ultra-high-strength-seismic bar bar irashobora kwitabwaho cyane. Ihinduka rizaganisha ku mpinduka zivangwa n’ibicuruzwa bikenewe ku isoko, bishobora gutonesha izo nganda zishobora gukora ibikoresho bigezweho.
Mugihe ibipimo bizamurwa, isoko ryisoko ryujuje ubuziranenge riziyongera. Ibikoresho byujuje ubuziranenge bushya bishobora gutegeka igiciro, bizashishikariza ibigo kuzamura ubuziranenge bwibicuruzwa.
