- Icyuma cy'umukara cyambaye ubusa: Ni cyiza cyane mu ikoreshwa ry'imbere no mu gutunganya ibikoresho mu mwanya wacyo.
- Irangi ririnda ingese: Ririnda ogisijeni n'ingese mu gihe cyo gutwara ibintu mu nyanja no kubibika mu gihe gito.
- Gushyushya no gutwika: Bikora irangi rikomeye kandi rikomeye rya zinc rituma ridashobora kwangirika igihe kirekire. Ni amahitamo meza ku nkombe, ahantu hakonje, inganda n'ahantu habi ho hanze kugira ngo byongere igihe cyo gukora inyubako.
1. Imikorere myiza cyane mu miterere no kugabanya ikiguzi
Imiterere myiza y'igice cy'icyuma itanga imbaraga kuva ku buremere. Imiterere ya H igabanya uburemere bw'icyuma kuva kuri 15% kugeza kuri 30% ugereranije n'imiterero isanzwe ya I mu gihe cy'imitwaro ingana, bigabanyiriza ikiguzi cy'ibikoresho n'uburemere budakomeye. Imiterere yoroheje yoroshya imirimo y'urufatiro kandi igagabanya ishoramari ry'umushinga wose.
2. Iyubahirizwa ry'amahame mpuzamahanga kugira ngo byoroshye kuyakoresha
Bihuye na EN 10025 S355JR/S355JO na ASTM A572 Icyiciro cya 50. Bishobora gukoreshwa mu buryo butaziguye nk'ibikoresho bisimburana nta kuvugurura, bikuraho ikiguzi cy'inyongera cy'isuzumabumenyi rya tekiniki n'impinduka.
3. Imiterere y’imashini yizewe n’umutekano w’inyubako
Ingufu z'umusaruro ≥355 MPa n'imbaraga zo gukurura 470–630 MPa bitanga ubushobozi bukomeye bwo gutwara ibintu, gukomera no guhindagurika kw'imitingito. Kugenzura neza ingano ya karuboni na CEV bitanga ubushobozi bwo gusudira bwizewe mu gukora no gushinga uruganda, bishyigikira inyubako zihamye zirambye.
4. Uburyo bwo kuvura ubuso bwihariye kugira ngo burwanye ingese
Amahitamo: ubuso bw'umukara buzungurutse, primer irinda ingese na galvanizing ishyushye. Uburinzi buhoraho bwa galvanizing bukora neza mu nkombe z'inyanja, ahantu hatose kandi hanini, bukongera igihe cyo gukora no kugabanya inshuro zo kubungabunga.
5. Gutanga serivisi mu buryo butaziguye no kugenzura ubuziranenge mu nganda
Igiciro cy’inganda zitaziguye ntikibamo ibiciro biri hagati. Buri gice kizana na EN 10204 3.1 MTC. Igenzura rya SGS, BV, TÜV rishyigikiwe n’abandi, kandi ireme ry’ubuziranenge rirahamye.
Iby’ubucuruzi n’ibya leta:Inkingi ndende, ibibuga by'indege, sitade, sisitemu z'inyubako zabanje gukoreshwa
Inganda n'Ibikoresho:Inzira z'ibiremereye byo mu bwoko bwa crane, imigozi y'uruganda, ububiko bunini bw'ibikoresho
Ibikorwaremezo n'Ingufu: Ibiraro byo gutwara abantu n'ibintu, imiyoboro y'amashanyarazi, ibyuma bitanga ingufu z'izuba n'umuyaga
Imashini zikoreshwa mu mazi n'izikomeye:Ibikoresho by'icyambu, hejuru y'urukuta rwo mu nyanja, inkingi z'ubucukuzi bw'amabuye y'agaciro, imitako y'ishingiro
Ibipfunyika bisanzwe
Gupakira mu mazi byo mu rwego rwo hejuru. Impapuro zose zifatanye n'imigozi y'icyuma gikomeye kugira ngo zikoreshwe neza kandi zinyure mu nyanja.
Uburinzi bw'ubuso
Amavuta arwanya ingese, irangi rya primer cyangwa irangi rishyushye riboneka, riteguwe hakurikijwe ibyo umukiriya akeneye.
Gushyira ikimenyetso no kumenya
Ibirango bidapfa amazi bishyirwa kuri buri gipfunyika, bigaragaza umubare w'ubushyuhe, urwego rw'icyuma, ingano, uburebure n'uburemere.
Amahitamo yo Kohereza
Ubwinshi bw'ibicuruzwa byoherezwa binyuze mu byuma bitwara ibintu byinshi; uburebure busanzwe bugera kuri metero 11.8 bushobora gushyirwa mu byuma bitwara ibintu bifite uburebure bwa metero 20 / metero 40.
Uko ibyo bitanga bihagaze
Irangi rishyushye cyangwa risutswe. Uburyo bwose bwo gukurikirana ibicuruzwa, hamwe n'Impamyabumenyi z'Ibizamini bya Mill Test Certificates (MTC) zemewe na EN 10204 3.1.
Igihe cyo Kuyobora no Kugenzura
Igihe cyo gukora: iminsi 7–30. Kohereza ibicuruzwa mu ruganda mu buryo butaziguye. Isuzuma rya SGS, BV cyangwa TÜV rikozwe n'abandi mbere y'uko bishyirwa mu bikorwa riraremewe.
Q1: Ese imirasire ya GB Q355B H-beams ishobora gusimbura EN S355JR na ASTM A572 Gr.50 mu buryo butaziguye?
A: Yego. Q355B ihuye na EN S355JR na ASTM A572 Gr.50 mu miterere y'ibanze ya mekanike, ifite imbaraga zo gutanga umusaruro wa 345–355 MPa. Ikora nk'igisimbuzo kiziguye kandi gihuye neza nta mpamvu yo gusubiramo imiterere cyangwa kuvugurura imiterere.
Q2: Ni irihe tandukaniro ry'ubukana bw'ingaruka hagati ya Q355B na S355JO?
A: Q355B igera ku ngufu za ≥34 J ku bushyuhe bwa 20°C, bingana na EN S355JR. Ku mishinga yo mu gace gakonje isaba ubuziranenge bwa S355JO (ubukonje bwa 0°C), dushobora guhindura ibice bya micro-alloy mu gihe cyo gukora kugira ngo twuzuze ibisabwa mu bushyuhe buri hasi no gutanga ibyemezo bya MTC byihariye kugira ngo byemezwe.
Q3: Ni uburebure busanzwe buhari, kandi bugira izihe ngaruka ku mikorere yo kohereza ibicuruzwa?
A: Uburebure bwacu busanzwe ni metero 6, metero 9 na metero 12, hamwe n'uburyo bworoshye bwo kohereza bujyanye n'ibikenewe bitandukanye byo gutwara ibintu:
- Kohereza amakontena: Dufite uburebure bwa metero 11.8 imbere bw'amakontena asanzwe ya metero 20/40, twaciye imiringoti munsi ya metero 11.8 kugira ngo dukore imirimo yoroshye.
- Kohereza ubwato bunini: Uburebure bwa metero 12 zose n'ingano zagutse zihariye zirahari, zikwiriye gutumiza umushinga mugari.
Ikibazo cya 4: Ese hari uburyo bwo kuvura ingese ku buso bukoreshwa hanze?
A: Dutanga uburyo bworoshye bwo gutunganya ubuso kugira ngo bujyane n'uburyo bwo gukoresha imbere no hanze:
- Icyuma cy'umukara kibisi: Ni cyiza cyane mu ikoreshwa ry'imbere no mu gutunganya ibikoresho mu nyubako.
- Irangi ririnda ingese: Ririnda ogisijeni n'ingese mu gihe cyo gutwara ibintu mu mazi no kubibika mu gihe gito.
- Gushyushya no gutwika: Bikora umwambaro munini wa zinc kugira ngo urwanye ingese igihe kirekire. Ni amahitamo meza ku nkombe, ahantu hakonje kandi hakomeye, bigatuma ubuzima bw'inyubako burushaho kuba bwiza.
Q5: Ni gute wakwizeza ko ibicuruzwa bifite ubuziranenge kandi ko bikurikiranwa neza?
A: Ibicuruzwa byose bishyigikira uburyo bwo gukurikirana ubuziranenge bwuzuye. Buri gice kizana icyemezo cya EN 10204 3.1 gisanzwe cya MTC, gikubiyemo umubare wuzuye w'ubushyuhe, imiterere y'ibinyabutabire n'amakuru y'imikorere ya mekanike. Igenzura rya SGS, BV, TUV n'izindi nzego zemewe rishyigikiwe byuzuye kugira ngo harebwe ubuziranenge bwizewe.
