Ni igihe ntarengwa cyo gukoresha ibyuma bikingira ibirahure?

Hindura: Viewmate irangi ry'ibirahure byose

Uburebure ntarengwa bw'inkingi z'ibirahuri buterwa n'ibintu nk'ubugari bw'ibirahuri, ubwoko bwabyo, uburyo bwo kubishyigikira, n'uburyo bikoreshwa. Muri rusange:

1. Ku kirahuri cyuzuyemo uburebure bwa ¼ santimetero gifite hejuru n'inyuma gusa, uburebure ntarengwa busabwa ni santimetero 60 (hafi mm 1524).
2. Ku kirahuri cyuzuyemo santimetero 1.5 gifite hejuru n'inyuma gusa, uburebure ntarengwa busabwa ni santimetero 96 (hafi mm 2438.4).
3. Ku kirahuri cyuzuyemo uburebure bwa santimetero 1.5 gifite hejuru n'inyuma gusa, uburebure ntarengwa busabwa ni santimetero 120 (hafi mm 3048).

Ariko, mu bikorwa bifatika, ubugari ntarengwa bw'inkingi z'ibirahuri akenshi ntibwifuzwa kurenza metero 1.2. Byongeye kandi, ku nkuta nini z'ibirahuri, hakenewe ibirahuri binini, nk'ibirahuri bifite ubugari bwa mm 18 ku nkuta zifite uburebure burenga metero 1.7. Muri icyo gihe, amategeko agenga inyubako zo mu gace n'amahame ajyanye nabyo bigomba kubahirizwa, kandi injeniyeri cyangwa umwubatsi wemewe agomba kugisha inama kugira ngo amenye imbaraga zikwiye z'inyubako n'ubugari ntarengwa ku bikorwa runaka.

Hariho amahame n'amabwiriza agenga umutekano ku birahuri byo gutwikiramo ibirahure, agenwa mu gihugu no mu nganda bireba. Ay'ingenzi ni aya akurikira:

• Ingingo rusange ku ishyirwa mu bikorwa ry'amategeko agenga imyubakire y'abaturage(GB 55031 – 2022): Biteganyijwe ko uruzitiro rw'ibirahuri rw'igice cy'ibaraza, inzira yo hanze, inzira yo mu nzu, atriamu, patio y'imbere, igisenge cyo kugendwaho n'ingazi bigomba gukoresha ikirahuri gifite laminated. Iyo igice cyo hasi cy'uruzitiro rw'ibirahuri kitarenze metero 5 uvuye ku uburebure bw'ubutaka ku ruhande rumwe, ubugari bw'ikirahuri gifite laminated bugomba kuba munsi ya mm 16.76.
• Ibisobanuro bya tekiniki ku ikoreshwa ry'ikirahure cy'inyubako(JGJ 113 – 2015): Ku birahuri byo mu nzu, iyo igice cyo hasi cy'ikirahuri kiri munsi ya metero 3 uvuye ku uburebure bwo hasi ku ruhande rumwe, hagomba gukoreshwa ikirahuri gikomeye gifite ubugari butari munsi ya mm 12 cyangwa ikirahuri gikomeye gifite ubugari butari munsi ya mm 16.76. Iyo uburebure buri hagati ya metero 3 na metero 5, hagomba gukoreshwa ikirahuri gikomeye gifite ubugari butari munsi ya mm 16.76.
• Ibipimo ngenderwaho bya tekiniki ku bijyanye n'inyubako zirinda ibyuma(JGJ/T 470 – 2019): Byavuzwe ko ikirahure gikoreshwa mu kurinda inyubako kigomba kuba kirimo ikirahure cya laminated, kandi kigomba kuba gifite impande n'imirongo. Inkombe - gusya igomba kuba nziza - gusya, kandi ubugari bwa chamfer ntibugomba kuba munsi ya mm 1. Iyi ngingo, hamwe na JGJ 113, igabanya ikoranabuhanga ryo gutunganya ikirahure, ibyo bikaba bigira ingaruka ku buryo butaziguye ku ikoreshwa ry'imirongo y'ikirahure mu mutekano.

Byongeye kandi, amwe mu mahame remezo yo mu gace n'ibisobanuro byihariye by'inganda nabyo bishobora kugira amabwiriza arambuye ku bijyanye n'uburebure bw'inkuta z'ibirahure. Mu gihe cyo gushushanya, kubaka no kwakira inkuta z'ibirahure, ibisabwa bireba bigomba gushyirwa mu bikorwa neza kugira ngo umutekano ukomeze kwiyongera.
