Ithini ikhowudi yee-handrails eKhanada?

Ihlelwe ngu: Viewmate All Glass Railing

EKhanada, imithetho ye-handrail kunye ne-guardrail ilawulwa kakhulu yiNational Building Code (NBC). Nangona kunjalo, amaphondo afana ne-Ontario (OBC) kunye ne-BC (BCBC) aneenguqu zawo ezithile.

1. Iimfuneko zoBude

Izinyuko: Ii-handrails mazibe phakathi kwe-865mm (34″) kunye ne-1070mm (42″) xa zilinganiswa ngokuthe nkqo ukusuka kumphetho ongaphambili we-stair tread (i-stair nosing).

Iigadi (Iibhalkoni/Iindawo zokuHlala): Ukuba i-handrail ikwasebenza njengomlindi (umz., kwibhalkoni), kufuneka ibe nokuphakama kwe-1070mm (42″) ubuncinane xa ithontsi lingaphezulu kwe-600mm (24″).

2. Ukuqonda

Ireyile kufuneka "ibambeke" ukuze ikwazi ukubamba ngokuqinileyo xa kuthe kwawa.

Iireyile ezijikelezayo: Ububanzi bangaphandle bufanele bube phakathi kwe-30mm kunye ne-43mm (i-OBC ichaza i-30mm–50mm).

IiRails Ezingajikeleziyo: Kufuneka zibe nomjikelezo ophakathi kwe-100mm kunye ne-155mm, kunye nobukhulu obukhulu be-cross-section obuyi-57mm.

Ukuvula: Kufuneka kubekho umgama ongaphantsi kwama-50mm (2″) phakathi kwe-handrail kunye nodonga/iglasi ukuze iminwe ikwazi ukudlula ngokukhululekileyo.

3. Ukuqhubeka kunye nokuphela

Ukuqhubekeka: Ii-handrails kufuneka ziqhubekeke kulo lonke ubude bezitebhisi. Kwizitebhisi ezibanzi (ngaphezulu kwe-1100mm), ii-handrails zinokufuneka kumacala omabini.

Ukuphela: Iziphelo mazibuyiselwe eludongeni okanye epalini. Oku kuthintela impahla okanye iingxowa ukuba zingabambeki esiporweni, nto leyo enokubangela ukuba ziwe.

4. Amandla oMthwalo kunye noLwakhiwo

I-NBC yaseKhanada ingqongqo kakhulu malunga nemithwalo yokhuseleko:

Izibambo kunye nee-guard kufuneka zinyamezele umthwalo oxineneyo we-1.0 kN (malunga ne-225 lbs) osetyenziswa kuyo nayiphi na indlela nangaliphi na ixesha.

Kwiinkqubo zeglasi, kufuneka kusetyenziswe iglasi yokhuseleko eqinisiweyo okanye elaminethiweyo ehlangabezana nemigangatho ye-CAN/CGSB.

5. "Isiphumo Sezinyuko" (Iindlela Zokukhusela)

Kangangeminyaka emininzi, iKhanada yayithintela iirelingi "ezinyukayo" (ezithe tye). Nangona i-NBC ka-2015/2020 iye yayikhulula kancinci le nto kwezinye izicelo zokuhlala, abahloli abaninzi basekuhlaleni basawunyanzelisa umthetho ongenakunyuswa. Ukuze uhlale ukhuselekile, qinisekisa ukuba uyilo lwakho aluvumeli umntwana ukuba anyuse iirelingi njengeleli.

Isigqibo: Soloko unxibelelana nesebe lezakhiwo likamasipala wakho ngaphambi kokuba u-odole izinto zokwakha. Nangona i-NBC ibonelela ngesikhokelo, abahloli basekuhlaleni banelizwi lokugqibela malunga "neemvume zokuhlala."
