Ubwoko bwaimirundo y'amabati y'icyuma
Dukurikije "Ikirundo cy'icyuma gishyushye gishyushye” (GB∕T 20933-2014), ikirundo cy'icyuma gishyushye gikozwe mu cyuma kirimo ubwoko butatu, ubwoko bwihariye n'amazina yacyo ni ibi bikurikira:Ikirundo cy'icyuma cyo mu bwoko bwa U, izina ry'ikode: Ikirundo cy'icyuma cyo mu bwoko bwa PUZ, izina ry'ikode: Ikirundo cy'icyuma gifata umurongo wa PZ, izina ry'ikode: PI Icyitonderwa: aho P ari inyuguti ya mbere y'ikirundo cy'icyuma mu Cyongereza (Pile), na U, Z, na I bihagarariye imiterere y'ikirundo cy'icyuma.
Urugero, ikirundo cy'icyuma gikoreshwa cyane mu bwoko bwa U, PU-400X170X15.5, gishobora kumvikana nk'ubugari bwa mm 400, uburebure bwa mm 170, n'ubugari bwa mm 15.5.
ikirundo cy'icyuma cyo mu bwoko bwa z
Ikirundo cy'icyuma cyo mu bwoko bwa U
Kuki atari ubwoko bwa Z cyangwa ubwoko bugororotse ahubwo ari ubwoko bwa U bukunze gukoreshwa mu buhanga? Mu by'ukuri, imiterere ya mekanike ya U-type na Z-type ni imwe muri rusange kuri imwe, ariko inyungu y'ikirundo cy'icyuma cya U-type igaragarira mu mikorere y'ibirundo byinshi by'icyuma bya U-type.
Ukurikije ishusho iri hejuru, bigaragara ko ubukana bwo kunama kuri metero imwe y'urukuta rw'icyuma rwo mu bwoko bwa U bunini cyane kuruta ubw'urukuta rw'icyuma rwo mu bwoko bwa U (aho urwego rw'umurongo utari wo hasi ruhinduka cyane) nyuma y'uko urukuta rw'icyuma rwo mu bwoko bwa U rukubiswe hamwe.
2. Ibikoresho by'icyuma bikozwe mu mpapuro
Icyuma Q345 cyarahagaritswe! Dukurikije "Icyuma cyo mu rwego rwo hasi cya Alloy High Strength Structural Steel" gishya gisanzwe cya GB/T 1591-2018, kuva ku ya 1 Gashyantare 2019, icyuma cya Q345 cyarahagaritswe gihinduka Q355, gihuye n'icyuma cya S355 gisanzwe cya EU. Q355 ni icyuma gisanzwe gifite imbaraga nkeya gifite imbaraga za 355MPa.
