Amabwiriza mashya yo kuvugurura ibyuma yageze ku rwego rwo hejuru kandi azashyirwa mu bikorwa ku mugaragaro mu mpera za Nzeri

Verisiyo nshya y’urwego rw’igihugu rushinzwe ikoreshwa ry’ibyuma GB 1499.2-2024 "icyuma gikoreshwa muri beto ishyigikiwe igice cya 2: ibyuma bishyushye bifite imbaho" izashyirwa mu bikorwa ku mugaragaro ku ya 25 Nzeri 2024

Mu gihe gito, ishyirwa mu bikorwa ry'amahame mashya rigira ingaruka nke ku giciro cyaagakoresho ko kugaruraumusaruro n'ubucuruzi, ariko mu gihe kirekire bigaragaza ingengabitekerezo rusange y'intego ya politiki yo kunoza ireme ry'ibicuruzwa byo mu gihugu no guteza imbere ibigo by'ibyuma kugeza ku rwego rwo hagati n'urwo hejuru rw'uruhererekane rw'inganda.
I. Impinduka zikomeye mu gipimo gishya: kunoza ubuziranenge no guhanga udushya mu mikorere
Ishyirwa mu bikorwa ry’amahame ngenderwaho ya GB 1499.2-2024 ryazanye impinduka nyinshi z’ingenzi, zigamije kunoza ireme ry’ibicuruzwa bya rebar no guhuza amahame ngenderwaho y’Ubushinwa ya rebar n’amahame mpuzamahanga. Izi mpinduka enye z’ingenzi ni izi:

1. Igipimo gishya gishimangira cyane ubushobozi bwo kwihanganira uburemere bwa rebar. By'umwihariko, kunyuranaho kwemewe kwa rebar y'umurambararo wa mm 6-12 ni ± 5.5%, mm 14-20 ni + 4.5%, naho mm 22-50 ni + 3.5%. Iri hinduka rizagira ingaruka zitaziguye ku buryo rebar ikora neza, bigasaba abakora kunoza urwego rw'imikorere n'ubushobozi bwo kugenzura ubuziranenge.
2. Ku bijyanye n'ingufu zikomeye zo mu bwoko bwa rebar nkaHRB500E, HRBF600Ena HRB600, amahame mashya ategeka ikoreshwa ry'uburyo bwo gutunganya indobo. Iki gisabwa kizanoza cyane ubwiza n'imikorere y'izi mashini zikomeye.imbaho ​​z'icyuma, no gukomeza guteza imbere inganda mu cyerekezo cyo guteza imbere ibyuma bikomeye.
3. Ku bijyanye n'ikoreshwa ry'ibikoresho byihariye, iri hame rishya rishyiraho ibisabwa mu mikorere y'umuruho. Iri hinduka rizamura ubuzima n'umutekano wa rebar mu gihe cy'imizigo ihindagurika, cyane cyane ku biraro, inyubako ndende n'indi mishinga ifite ibisabwa byinshi mu mikorere y'umuruho.
4. Uburyo bwo gupima busanzwe buvugurura uburyo bwo gupima n'uburyo bwo gupima, harimo no kongeramo ikizamini cyo kugonga inyuma cya "E" grade rebar. Izi mpinduka zizamura ukuri n'ubwizerwe bw'ibizamini by'ubuziranenge, ariko zishobora no kongera ikiguzi cyo gupima ku bakora.
Icya kabiri, ingaruka ku kiguzi cy'umusaruro
Ishyirwa mu bikorwa ry’iri hame rishya rizafasha umuyobozi w’ibigo bikora imitako kuzamura ireme ry’ibicuruzwa, kongera ubushobozi bwo guhangana ku isoko, ariko kandi bizana ikiguzi gito cy’umusaruro: nk’uko ubushakashatsi bubigaragaza, umuyobozi w’ibigo bikora ibyuma akurikije ibiciro bishya by’umusaruro biziyongeraho hafi 20 Yuan kuri toni.
Icya gatatu, ingaruka ku isoko

Amabwiriza mashya azateza imbere iterambere n'ikoreshwa ry'ibikoresho by'icyuma bikomeye cyane. Urugero, ibyuma bifite imbaraga nyinshi za MPa 650 bishobora kwitabwaho cyane. Iri hinduka rizatuma habaho impinduka mu ruvange rw'ibicuruzwa n'ubukene bw'isoko, bishobora gutuma inganda z'ibyuma zishobora gukora ibikoresho bigezweho zikora ibikoresho bigezweho.
Uko amahame azamurwa, niko isoko ry’ibikoresho byujuje ibisabwa biziyongera. Ibikoresho byujuje ibisabwa bishobora gusaba ikiguzi cy’ikirenga, ibyo bikazashishikariza amasosiyete kunoza ireme ry’ibicuruzwa.
