Iyini ikhodi yezandla zokuphatha eCanada?

Kuhlelwe ngu: Viewmate All Glass Railing

ECanada, imithethonqubo ye-handrail kanye ne-guardrail ilawulwa kakhulu yi-National Building Code (NBC). Kodwa-ke, izifundazwe ezifana ne-Ontario (OBC) kanye ne-BC (BCBC) zinezinhlobo zazo ezithile.

1. Izidingo Zokuphakama

Izitebhisi: Izinsika zokuphatha kumele zibe phakathi kuka-865mm (34″) no-1070mm (42″) uma zilinganiswa ziqonde phezulu kusukela emphethweni ongaphambili wesitebhisi sokugibela izitebhisi (ikhala lezitebhisi).

Onogada (Ama-Balcony/Ama-Landing): Uma i-handrail isebenza njengomqaphi (isb., ebhalkhoni), kumele okungenani ibe ukuphakama okungu-1070mm (42″) uma ukwehla kungaphezu kuka-600mm (24″).

2. Ukuqonda

Isitimela kumele "sibambeke" ukuze sibambe kahle uma kwenzeka ukuwa.

Imizila Ejikelezayo: Ububanzi bangaphandle kufanele bube phakathi kuka-30mm no-43mm (i-OBC ichaza u-30mm–50mm).

Imizila Engajikelezi: Kumelwe ibe nomngcele ophakathi kuka-100mm no-155mm, kanye nobukhulu obukhulu besigaba esiphambeneyo obungu-57mm.

Ukuvuleka: Kumelwe kube nomkhawulo okungenani ongu-50mm (2″) phakathi kwe-handrail nodonga/ingilazi ukuze iminwe ikwazi ukudlula ngokukhululeka.

3. Ukuqhubeka Nokuqedwa

Ukuqhubeka: Izibambo zokubambelela kumele ziqhubeke ubude bonke bezitebhisi. Ezitebhisini ezibanzi (ngaphezu kuka-1100mm), izibambo zokubambelela zingadingeka kuzo zombili izinhlangothi.

Ukuphela: Iziphetho kumele zibuyiselwe odongeni noma esigxotsheni. Lokhu kuvimbela izingubo noma izikhwama ukuthi zingabambeki esitimeleni, okungaholela ekuweni.

4. Amandla Omthwalo Nokwakheka

I-NBC yaseCanada iqine kakhulu maqondana nemithwalo yezokuphepha:

Izibambo zokuphatha kanye nezihlangu kumele zikwazi ukumelana nomthwalo oqinile ongu-1.0 kN (cishe amakhilogremu angu-225) osetshenziswa kunoma iyiphi indlela nganoma iyiphi indawo.

Ezinhlelweni zengilazi, ingilazi yokuphepha ethambile noma eqinisiwe ehlangabezana nezindinganiso ze-CAN/CGSB kumele isetshenziswe.

5. "Umphumela Wezitebhisi" (Izivikelo Zokuvikela)

Sekuyiminyaka eminingi iCanada ivimbela izindonga “ezikhuphukayo” (ezivundlile). Nakuba i-NBC ka-2015/2020 ikhulule lokhu kancane kwezinye izinhlelo zokusebenza zokuhlala, abahloli abaningi bendawo basasebenzisa umthetho ongakhuphukeli. Ukuze uphephe, qiniseka ukuthi umklamo wakho awuvumeli ingane ukuthi ikhuphuke izindonga njengezitebhisi.

Isinqumo: Njalo thintana nomnyango wakho wokwakha kamasipala wendawo ngaphambi koku-oda izinto zokwakha. Nakuba i-NBC inikeza uhlaka, abahloli bendawo banezwi lokugcina mayelana "nezimvume zokuhlala."
