Ibyiza by'inyubako zikozwe mu buryo bukonje kandi zivanze

Ibyiza by'imiterere y'icyuma gikonje cyasutswe mu buryo bw'imiterere

Ibisobanuro bigufi:

Mu kubaka inyubako n'inyubako, guhitamo ibikoresho bigira uruhare runini mu gutuma umusaruro wa nyuma uramba kandi ugakomera. Kimwe mu bikoresho bikunzwe mu nganda z'ubwubatsi ni icyuma gikonje gikozwe mu buryo bwa welded. Iki gikoresho gishya gitanga inyungu nyinshi, bigatuma kiba amahitamo ya mbere mu mishinga myinshi y'ubwubatsi.

Icyuma gikonje gikorwa no gupfunyika no gukora impapuro z'icyuma cyangwa imigozi ku bushyuhe bw'icyumba nta bushyuhe bukoreshejwe. Ubu buryo butanga ibikoresho bikomeye kandi biramba kurusha icyuma gikonje. Iki cyuma gikonje gitanga inyungu nyinshi z'ingenzi iyo gihujwe hamwe kugira ngo kibe ibice by'imiterere.

Imwe mu nyungu z'ingenzi zaibicurane inyubako zakozwe mu buryo bwa svede Icyuma ni igipimo cyacyo gikomeye cyane hagati y’uburemere n’imbaraga. Ibi bivuze ko gitanga imbaraga nyinshi mu gihe cyoroshye, bigatuma byoroha gufata no gutwara mu gihe cyo kubaka. Byongeye kandi, imbaraga nyinshi z’icyuma gikonje zituma habaho imiterere y’inyubako nto kandi nziza, bigatuma umwanya munini urushaho kuba mwiza kandi bikagabanya ikoreshwa ry’ibikoresho.

Indi nyungu ikomeye y'icyuma gikonjeshwa gikozwe mu buryo bukonje ni uburyo giteye kimwe kandi gihamye. Uburyo gikonjeshwa butuma icyuma gikomeza kugira imiterere ihamye mu bikoresho byose, bigatuma gitanga umusaruro ushoboka kandi wizewe. Uku gukonjeshwa ni ingenzi cyane kugira ngo inyubako ya nyuma ibe nziza kandi itekanye.

Uretse gukomera no kuba ibintu bihamye, icyuma gikonje cyakozwe mu buryo bwa Welded Structural steel gitanga ubuziranenge n'ubuziranenge bwiza cyane. Uburyo bwo gukora mu buryo bwa konje butuma habaho kwihanganirana no gushushanya neza, bigatuma ibice by'icyuma bihura neza mu gihe cyo guteranya. Uru rwego rwo gukora neza ni ingenzi kugira ngo haboneke umusaruro mwiza kandi ushimishije.

Byongeye kandi, icyuma gikonje cyakozwe mu buryo bwa Welded Structural steel kirakoreshwa mu buryo butandukanye kandi gishobora guhindurwa kugira ngo gihuze n'ibikenewe mu mushinga runaka. Gishobora kugirwa mu buryo bworoshye no gutegurwa mu buryo butandukanye, bigatuma habaho imiterere igoye y'inyubako. Ubu buryo bworoshye butuma gikoreshwa mu buryo butandukanye kuva mu bwubatsi bw'amazu kugeza ku nganda.

Gukoresha ibyuma bikonje byakozwe mu buryo bwa Welded Structural nabyo bigira uruhare mu mikorere irambye y'ubwubatsi. Imiterere yabyo yoroheje igabanya umutwaro rusange ku rufatiro n'inyubako zishyigikira, bigatuma habaho kuzigama amafaranga ndetse n'inyungu ku bidukikije. Byongeye kandi, kongera gukoresha ibyuma mu buryo bwa ongera gukoreshwa bituma biba amahitamo meza ku mishinga y'ubwubatsi.

Muri make, icyuma gikonje cyakozwe mu buryo bwa Welded Structural gifite ibyiza byinshi bituma kiba amahitamo meza ku mishinga y'ubwubatsi. Igipimo cyacyo gikomeye hagati y’uburemere n’imbaraga, uburinganire, ubuziranenge, ubwisanzure n’uburambe bituma kiba ibikoresho by’agaciro mu gukora inyubako ziramba kandi zinoze. Uko inganda z’ubwubatsi zikomeza gutera imbere, icyuma gikonje cyakozwe mu buryo bwa Welded Structural ...

Ibanjirije iyi: Imiyoboro y'amazi yo mu bwoko bwa Spiral Seam

Ibikurikira: Ibyiza byo gukoresha imiyoboro y'imyubakire ifite ibice bidafite icyobo mu bwubatsi
