Isiphatho sesandla sifanele siqale size sime phi?

Ngokwe-International Residential Code (IRC), i-handrail kufuneka iqale kwaye ime kwiindawo ezibonelela ngenkxaso eqhubekayo kuye nabani na osebenzisa izitebhisi, kunye nolwandiso oluthile lokhuseleko phezulu nasezantsi. Le mithetho yenzelwe ukuthintela ukuwa apho ugqatso lwezitebhisi luqala kwaye luphela khona.

1. Nazi iimfuno ezichanekileyo:

Indawo Yokuqala (ezantsi kwezinyuko)
I-handrail kufuneka iqale ngqo ngaphezulu kwempumlo yokuqala yokunyathela (umphetho wenyathelo elisezantsi). Emva koko kufuneka yolulele phambili ngokuthe tye ubuncinane ii-intshi ezili-12 (305 mm) ngaphaya kwempumlo ye-bottom riser. Olu lwandiso lubonelela ngenkxaso ezinzileyo ngaphambi kokuba umntu anyuse inyathelo lakhe lokuqala.

Indawo yokuma (ephezulu kwezinyuko)
Ngokufanayo, phezulu, i-handrail kufuneka iqhubeke ubuncinane ngee-intshi ezili-12 (305 mm) ngokuthe tye ngaphaya kwempumlo ye-riser ephezulu. Olu lwandiso lubalulekile ekunikeni inkxaso njengoko umsebenzisi ethatha inyathelo lakhe lokugqibela ekufikeni. Kufuneka iqhubeke, ngokuphakama okufanayo, ecaleni kwendawo yokufika ekufutshane ukuba izinyuko zikhokelela kwenye indawo yokubhabha okanye zitshintsha indlela.

2. Umthetho Oqhubekayo
Phakathi kwezi ndawo, i-handrail kufuneka iqhubeke ubude bonke bezitebhisi, ngaphandle kokuphazanyiswa ziintsika okanye ezinye izithintelo.

Indlela ekhuselekileyo yesandla ilandela le ndlela:
Ukuhla (ulwandiso oluthe tye lwe-intshi eziyi-12+) → Ukwehla/ukunyuka kunye nomthambeka wezitebhisi → Ukuhla okusezantsi/okuphezulu (ulwandiso oluthe tye lwe-intshi eziyi-12+)

3. Iimpembelelo eziphambili ezisebenzayo
1）Ungaze uqale okanye ume ngokuthe ngqo kwinqanaba: Ukuphelisa ngequbuliso umqolo phezulu okanye ezantsi kwempumlo kukwaphulwa kwekhowudi okuqhelekileyo nokuyingozi.
2）Nxibelelana nesebe lezakhiwo lendawo yakho: Soloko ujonga iikhowudi zakho zengingqi kuqala, njengoko ezinye iindawo zinokuba nezilungiso (umz., ezifuna ulwandiso olude).
3）Kwii-ramps: Umthetho ofanayo wokwandisa othe tye we-intshi ezili-12 uyasebenza phezulu nasezantsi kwee-ramps ezifikelelekayo.

Ngamafutshane, i-handrail efakwe kakuhle ayipheleli kwinqanaba lokugqibela. Iqala xa usondela ekufikeni kwaye iphele ngokukhuselekileyo xa uphuma ekufikeni, ukuqinisekisa ukuba inkxaso ekhuselekileyo nebambekayo isoloko ifikeleleka kuyo yonke indawo yokunyuka nokwehla.
