HEA HEB HEM H Beam H Steel Beam – Inkingi z'Uburayi za Flange
UKO IBICURUZWA BIGENDA
Izi nyito zigaragaza ubwoko butandukanye bw'imirasire ya IPE hashingiwe ku bipimo byayo n'imiterere yayo:
- Imirasire ya HEA (IPN): Izi ni imirasire ya IPE ifite ubugari bwa flange bunini cyane n'ubugari bwa flange, bigatuma ikoreshwa mu bikorwa bikomeye by'inyubako.
- Imitako ya HEB (IPB): Iyi ni imitako ya IPE ifite ubugari buringaniye n'ubugari bw'imitako, ikoreshwa cyane mu bwubatsi mu bikorwa bitandukanye by'ubwubatsi.
- Imirasire ya HEM: Iyi ni imirasire ya IPE ifite flange ndende cyane kandi nto, itanga imbaraga nyinshi n'ubushobozi bwo gutwara imizigo.
Turabibona6m S275jr H-Beamikunze gukoreshwa mu nyubako. Izi migi zigenewe gutanga ubushobozi bwihariye bwo kubaka, kandi guhitamo ubwoko bwo gukoresha biterwa n'ibisabwa n'umushinga runaka w'ubwubatsi.

IBIKORESHO
Imirasire ya HEA, HEB, na HEM ni ibice bisanzwe by’i Burayi bya IPE (I-beam) bikoreshwa mu bwubatsi no mu bwubatsi. Dore bimwe mu bintu by’ingenzi bigize buri bwoko:
Imirasire ya HEA (IPN):
Ubugari bw'urukiramende n'ubugari bw'urukiramende
Bikwiriye gukoreshwa mu nyubako zikomeye
Itanga ubushobozi bwiza bwo gutwara imizigo no kudacika intege
Imirasire ya HEB (IPB):
Ubugari bw'urukiramende n'ubugari bw'urukiramende
Ikoreshwa mu buryo butandukanye kandi ikunze gukoreshwa mu bwubatsi mu bikorwa bitandukanye by'ubwubatsi
Itanga uburinganire bw'imbaraga n'uburemere
Imirasire ya HEM:
By'umwihariko, icyuma gifunganye cyane kandi kigufi
Itanga imbaraga nyinshi n'ubushobozi bwo gutwara imizigo
Byagenewe gukoreshwa mu buryo bukomeye kandi butuma umuntu agira umuvuduko mwinshi
Iyi migi igenewe kuzuza ibisabwa byihariye mu nyubako kandi itoranywa hashingiwe ku mikoreshereze n'ibikenewe mu nyubako cyangwa mu nyubako.
UBUSABIZI
Imirasire ya HEA, HEB, na HEMifite uburyo bwinshi bwo gukoresha mu bwubatsi no mu nganda z’ubwubatsi. Zimwe mu nzira zikunze gukoreshwa zirimo:
- Kubaka inyubako:Imitako y'icyuma ifite ishusho ya Hzikunze gukoreshwa mu kubaka inyubako z'ubucuruzi n'inganda kugira ngo zitange inkunga y'inyubako ku mazu, ku bisenge, no ku bindi bintu bitwara imizigo.
- Kubaka ibiraro: Bikoreshwa mu kubaka ibiraro kugira ngo bishyigikire imiterere y'umuhanda n'ibindi bice by'inyubako.
- Inganda: Imitako ya HEA, HEB, na HEM ikunze gukoreshwa mu kubaka inganda nk'ububiko, inganda zikora, n'ububiko.
- Imiterere y'Inyubako: Ikoreshwa mu gukora imiterere y'inyubako nini n'imishinga y'ibikorwa remezo, itanga inkunga ku nkuta, ibisenge, n'ibindi bintu by'inyubako.
- Inkunga y'ibikoresho: Iyi mirasire ikoreshwa mu gushyigikira imashini ziremereye n'ibikoresho mu nganda zitandukanye.
- Imishinga y'ibikorwa remezo: Imiyoboro ya HEA, HEB, na HEM nayo ikoreshwa mu kubaka imishinga y'ibikorwa remezo nk'imiyoboro y'amazi, ibibuga by'indege, n'inganda z'amashanyarazi.
Muri rusange, iyi miyoboro ni ingenzi cyane mu gutanga inkunga ikomeye kandi yizewe mu mishinga itandukanye y’ubwubatsi n’ubwubatsi. Kuba ifite ubushobozi bwo gukora ibintu bitandukanye, imbaraga, n’ubushobozi bwo gutwara imizigo bituma iba ingenzi mu mishinga igezweho y’inyubako n’ibikorwa remezo.
IGENZURA RY'IBICURUZWA
Ibisabwa kugira ngo icyuma gikoreshwe mu ishusho ya H bikubiyemo ahanini ibi bikurikira:
Ubwiza bw'isura: Ubwiza bw'isura y'icyuma gifite ishusho ya H bugomba kubahiriza amahame n'ibisabwa mu gutondeka. Ubuso bugomba kuba bworoshye kandi burambuye, nta mikorobe, imishwanyagurike, ingese n'ibindi bidafite ubusembwa.
Ingano za jeometri: Uburebure, ubugari, uburebure, ubugari bw'urukuta, ubugari bw'urukuta n'ibindi bipimo by'icyuma gifite ishusho ya H bigomba kubahiriza amahame n'ibisabwa mu gutondeka.
Ihindagurika ry'icyuma: Ihindagurika ry'icyuma gifite ishusho ya H rigomba kubahiriza amahame n'ibisabwa mu gutondeka. Rishobora kumenyekana hapimwa niba imiterere y'icyuma kiri ku mpera zombi z'icyuma gifite ishusho ya H ingana cyangwa hakoreshejwe icyuma gipima.
Guhindura: Guhindura icyuma gifite ishusho ya H bigomba kubahiriza amahame n'ibisabwa mu gutondeka. Bishobora kumenyekana hapimwa niba uruhande rw'icyuma gifite ishusho ya H ruhagaze cyangwa rufite metero ipima.
Guhindagurika kw'uburemere: Uburemere bw'icyuma gifite ishusho ya H bugomba kubahiriza amahame n'ibisabwa mu gutondeka. Guhindagurika kw'uburemere bishobora kumenyekana hakoreshejwe gupima.
Imiterere y'ibinyabutabire: Niba icyuma gifite ishusho ya H gikeneye gusudira cyangwa gutunganywa mu bundi buryo, imiterere yacyo y'ibinyabutabire igomba kubahiriza amahame n'ibisabwa mu gutondeka.
Imiterere ya mekanike: Imiterere ya mekanike y'icyuma gifite ishusho ya H igomba kubahiriza amahame ngenderwaho n'ibisabwa mu gutondeka, harimo imbaraga zo gukurura, aho bigarukira, uburebure n'ibindi bimenyetso.
Isuzuma ritangiza: Niba icyuma gifite ishusho ya H gisaba isuzuma ritangiza, kigomba kugeragezwa hakurikijwe ibipimo ngenderwaho n'ibisabwa kugira ngo harebwe ko ubuziranenge bwacyo bw'imbere ari bwiza.
Gupakira no gushyira ikimenyetso: Gupakira no gushyira ikimenyetso mu byuma bifite ishusho ya H bigomba kubahiriza amahame n'ibisabwa mu gutumiza kugira ngo byorohere gutwara no kubika.
Muri make, ibisabwa byavuzwe haruguru bigomba kwitabwaho byuzuye mu gusuzuma icyuma gifite ishusho ya H kugira ngo harebwe ko ubuziranenge bwacyo bwujuje ibisabwa n'ibisabwa mu gutondeka, no guha abakoresha ibikoresho byiza by'icyuma gifite ishusho ya H.
GUPIKA NO KOHEREZA
Gupakira no kurinda:
Gupfunyika bigira uruhare runini mu kurinda ubuziranenge bw'icyuma cya ASTM A36 H mu gihe cyo gutwara no kubika. Ibikoresho bigomba gupfunyikwa neza, hakoreshejwe imigozi ikomeye cyangwa imigozi kugira ngo hirindwe ko byangirika cyangwa se bigashobora kugenda. Byongeye kandi, hagomba gufatwa ingamba zo kurinda icyuma kwangirika n'ubushuhe, umukungugu, n'ibindi bintu bibangamira ibidukikije. Gupfunyika ibipfunyika mu bikoresho birwanya ikirere, nk'ibya pulasitiki cyangwa imyenda idapfa amazi, bifasha mu kurinda ingese n'ingese.
Gupakira no gufunga kugira ngo bikoreshwe mu gutwara abantu:
Gupakira no gufata ibyuma bipakiye ku modoka itwara imizigo bigomba gukorwa witonze. Gukoresha ibikoresho bikwiye byo guterura, nka forklifts cyangwa cranes, bituma habaho umutekano kandi neza. Imitako igomba gukwirakwizwa neza kandi igashyirwa ku murongo kugira ngo hirindwe kwangirika kw'inyubako mu gihe cyo kuyitwara. Iyo imaze gupakirwa, gufata imizigo n'imigozi ihagije, nk'imigozi cyangwa iminyururu, bitanga icyizere cyo kugumana umutekano kandi bikarinda kwimuka.
GUSURA ABAKIRIYA
