Thano haribikoresho byinshi byokoresha ubushyuhe bwumuriro bidukikije, ukurikije gukoresha ibihe bitandukanye kugirango dushyire mubikorwa, nkibisanzwe harimo ibikoresho byo gutwika amashyanyarazi hejuru yinzu cyangwa ibikoresho byo mu rukuta rwo hanze, ibyo uyu munsi byibanda ku gushyira mu byiciro ibikoresho byo kubika inkuta zo hanze kandi byihariye gushyira mu byiciro.
Hamwe niterambere ryihuse ryubwubatsi bugezweho, dufite byinshi bisabwa hejuru kumikorere yurukuta rwo hanze. Tugomba kwiga no guhanga udushya twububiko bwa plaque hamwe ningaruka nziza zo gukumira, imikorere myiza yo gutwika, kurengera ibidukikije bibisi, kandi igiciro gishobora kwemerwa nabantu bose.
Igipimo cyigihugu cyacu GB8624-97 kigabanya imikorere yo gutwika ibikoresho byubwubatsi mu byiciro bikurikira:
1.Icyiciro: ibikoresho byubaka bidashya: hafi nta bikoresho byaka.
2.B1: ibikoresho byubaka byaka: ibikoresho byaka bifite ingaruka nziza zo kwirinda flame. Biragoye gufata umuriro mu kirere imbere yumuriro ufunguye cyangwa munsi yubushyuhe bwo hejuru, ntibyoroshye gukwirakwira vuba, kandi iyo inkomoko yumuriro ikuweho, gutwikwa bizahita bihagarara.
3.Urwego rwa B2: ibikoresho byubaka bishobora gutwikwa: ibikoresho bishobora gutwikwa bifite ingaruka zimwe zumuriro. Mu kirere imbere yumuriro ufunguye cyangwa munsi yubushyuhe bwo hejuru bizahita byaka umuriro, byoroshye kuganisha ku gukwirakwiza umuriro, nkibiti byimbaho, ikadiri yimbaho, ibiti bikozwe mu giti, ingazi zimbaho, nibindi.
4.B3: ibikoresho byubaka byaka: nta ngaruka zo gukumira umuriro, byoroshye gutwika, ibyago byinshi byumuriro.
Ibikoresho byo kubika urukuta hanze bigabanijwe ukurikije igipimo cyumuriro:
1.imikorere yo gutwika Urwego rwibikoresho byokwirinda: ubwoya bwamabuye, ubwoya bwikirahure, ikirahure cyinshi, ceramic ifuro, sima ifuro, perlite ifunze, nibindi.
2.imikorere yo gutwika kubikoresho byo mu rwego rwa B1: nyuma yo kuvura bidasanzwe ikibaho cya polystirene (XPS) / nyuma yo kuvura bidasanzwe polyurethane (PU), fenolike, ifu ya rubber polystirene, nibindi.
3.gutwika imikorere ya B2 yo mu rwego rwo kubika ibikoresho: ikibaho cya polystirene (EPS), ikibaho cya polystirene (XPS), polyurethane (PU), polyethylene (PE), nibindi.
