Ikibanza cyo mu majyaruguru y'uburasirazuba
Impande icyenda zidasanzwe zubatswe zubatswe umwanya wibikoresho / ibikoresho fatizo Q235B umuyoboro usudutse / uburebure bwa metero 33 / uburebure bwa metero 76.55 / uburebure bwa metero 436.55.
Ibisabwa byo gukingira umuriro mubyuma byubatswe:
1. Igipimo cyo kurwanya umuriro cyuyu mushinga ni Icyiciro cya II;Igipimo cyo kurwanya inkongi y'umuriro kuri buri kintu kigizwe n'umutwaro w'inyubako kigomba kubahiriza ingingo zijyanye n’urwego rw’igihugu "Code for Fire Fire in Design Architecture" GB 50016-2014 (Edition 2018).
2. Mubyuma byumwanya wibyuma byubaka uyu mushinga.Imipaka irwanya inkingi yinkingi hamwe ninkingi hagati yinkingi igomba kugera kumasaha 2.5, kandi hagomba gukoreshwa impuzu zidindiza umuriro.Umupaka wo kurwanya umuriro wibiti byibyuma hamwe nubutaka bigomba kugera kumasaha 1.5, kandi hagomba gukoreshwa ibishishwa bito cyane.Abagize imitwaro yo hejuru yinzu, ibisenge hamwe nudukoni twa karuvati bagomba kugira igipimo cyumuriro cyamasaha 1.0, hamwe nudukingirizo duto duto.Ikizamini cyo guhuza ibipimo byo kuzimya umuriro hamwe n’irangi hagati bizakorwa, kandi icyuma cyatoranijwe cyo kuzimya umuriro cyujuje ibyangombwa bisabwa n’amabwiriza yo kurinda umuriro..
3. Ibikoresho byo kuzimya umuriro bigomba kuba ibicuruzwa byatsinze ikizamini cyikigo cyigihugu gishinzwe ibizamini kandi byemejwe n’ishami ry’umuriro, kandi bigomba guhuzwa na primer.Imikorere, ubunini bwububiko hamwe nibisabwa byujuje ubuziranenge byatoranijwe bigomba gukurikiza ibipimo ngenderwaho byigihugu "Fireproof Coatings for Structures" (GB14907-2018) hamwe nuburinganire bwigihugu "Gukoresha Ikoranabuhanga rya Fireproof Coatings for Steel Structures" (CECS24 -2020).
4. Nyuma yimiterere yicyuma cyubatswe, ibyuma byo gusudira nibice byangiritse byubwubatsi bigomba kubanza gukurwaho, kandi hejuru bigomba gusuzumwa.Irangi rimaze kurangira, ubugari bwa firime irangi burageragezwa, kandi ikoti irwanya umuriro irashobora gusiga irangi nyuma yo kuzuza ibisabwa.
5. Igice fatizo cyo gutwika umuriro ntigishobora kugira umwanda nkamavuta, umukungugu numucanga wibyondo;gutwika umuriro ntibishobora gukoreshwa cyangwa kubura, kandi igifuniko kigomba gufungwa nta gusiba, gutobora, kwiheba kugaragara, ifu irekuye, laitance nizindi nenge zigaragara, Mastoid igomba kuvaho.
6. Kugirango ugenzure umuriro hamwe nigishushanyo mbonera cyibikoresho, hakoreshwa uburyo bwo kurwanya umuriro, kandi umwanya wabonye ikizamini urasabwa tm ≥ tdtm: igipimo nyacyo cyo kurwanya umuriro cyibikoresho byubatswe munsi yumuriro td: the gushushanya imbibi zumuriro wibice byibyuma, reba ibisabwa hejuru.Umubare nyawo wo kurwanya umuriro wibice urashobora gukurikiza ibipimo byigihugu "Uburyo bwo gupima umuriro mukubaka ibice - Igice cya 1: Ibisabwa muri rusange" GB / T 9978.1-2008, "Uburyo bwo gupima umuriro kubice byubaka - Igice cya 5 . kubirwanya umuriro wibice byubaka - Igice cya 7: Ibisabwa bidasanzwe ku nkingi "GB / T9978.7-2008 Nukuri.
