Ni iki gipimo cya ASTM kuri C channel?

Mu bwubatsi no mu bwubatsi, ikoreshwa ry'icyuma cy'imiyoboro (akenshi kitwa icyuma cy'igice cya C) ni ikintu gisanzwe cyane. Iyi miyoboro ikozwe mu cyuma kandi ifite ishusho ya C, niyo mpamvu yitwa. Ikoreshwa cyane mu nganda z'ubwubatsi kandi ifite uburyo bwinshi bwo kuyikoresha. Kugira ngo ubwiza n'imiterere y'icyuma cy'igice cya C bikomeze kubungabungwa, Ishyirahamwe ry'Abanyamerika ryita ku bipimo n'ibikoresho (ASTM) rishyiraho amahame ngenderwaho kuri ibyo bicuruzwa.

Igipimo ngenderwaho cya ASTM kuriIcyuma gifite ishusho ya Cyitwa ASTM A36. Iri hame rikubiyemo imiterere y’icyuma cya karuboni cyiza cyo gukoreshwa mu kubaka ibiraro n’inyubako bikozwe mu migozi, bipfundikiye cyangwa bisudiye, ndetse no mu nyubako rusange. Iri hame rigaragaza ibisabwa ku miterere, imiterere ya mekanike n’ibindi bintu by’ingenzi biranga icyuma cya karuboni C-sections.

Kimwe mu bisabwa by'ingenzi by'ingenzi ku gipimo cya ASTM A36 kuriIcyuma cy'umuyoboro wa Cni imiterere y'ibinyabutabire by'icyuma gikoreshwa mu gukora. Ibipimo ngenderwaho bisaba ko icyuma gikoreshwa mu bice bya C kigira urugero runaka rwa karuboni, manganese, fosifore, sulfur na umuringa. Ibi bisabwa byemeza ko icyuma gikoreshwa mu miyoboro ya C gifite imiterere ikenewe kugira ngo gitange imbaraga n'uburambe bikenewe mu miterere y'inyubako.

Uretse imiterere y’ibinyabutabire, amahame ya ASTM A36 anagaragaza imiterere y’icyuma gikoreshwa mu cyuma cya C-section. Ibi birimo ibisabwa kugira ngo icyuma gikomere, imbaraga zo gukurura no kurekura. Iyi miterere ni ingenzi kugira ngo icyuma cya C-channel kigire imbaraga n’ubushobozi bwo kugenda neza kugira ngo gishobore kwihanganira imitwaro n’imihangayiko bivuka mu bwubatsi.

Amabwiriza ya ASTM A36 kandi areba ubushobozi bwo kwihanganira ibintu hamwe n’ibisabwa ku buryo bworoshye no kugorama ku byuma bigize igice cya C. Ibi bipimo byemeza ko ibice bya C bikozwe muri ubu buryo byujuje ingano n’imiterere bisabwa kugira ngo bikoreshwe mu mishinga y’ubwubatsi.

Muri rusange, igipimo cya ASTM A36 ku byuma bifite ishusho ya C gitanga urutonde rwuzuye rw'ibisabwa kugira ngo ibi byuma bibe byiza kandi bikore neza. Mu kubahiriza iri hame, abakora ibikoresho bashobora kwemeza ko ibice bya C bakora byujuje ibisabwa mu bwubatsi.

Muri make, igipimo ngenderwaho cya ASTM cyaIcyuma cy'umuyoboro wa C, izwi nka ASTM A36, igaragaza ibisabwa ku miterere y’ibinyabutabire, imiterere ya mekanike, n’ubushobozi bwo kwihanganira ibi byuma. Mu gihe byujuje ibi bisabwa, abakora bashobora gukora ibice bya C byujuje ibisabwa ku buryo buhanitse mu mirimo itandukanye yo kubaka. Byaba ibiraro, imashini z’inganda cyangwa inyubako, gukurikiza amahame ya ASTM y’icyuma cya C bishimangira umutekano n’ubwizerwe bw’icyuma gikoreshwa.
