Ngokusho kwe-International Residential Code (IRC), i-handrail kumele iqale futhi ime ezindaweni ezihlinzeka ngokusekelwa okuqhubekayo kunoma ubani osebenzisa izitebhisi, kanye nokwelulwa okuqondile kokuphepha phezulu nangaphansi. Le mithetho yenzelwe ukuvimbela ukuwa lapho ukugijima kwezitebhisi kuqala futhi kuphele khona.
1. Nazi izidingo eziqondile:
Indawo Yokuqala (Ezansi Kwezitebhisi)
I-handrail kumele iqale ngqo ngaphezu kwekhala lokuqala lokunyathela (umphetho wesinyathelo esingezansi). Ngemuva kwalokho kumele yeluleke ngokuvundlile iye phambili okungenani amasentimitha angu-305 (305 mm) ngale kwekhala le-bottom riser. Lesi sandiso sinikeza ukwesekwa okuzinzile ngaphambi kokuba umuntu athathe isinyathelo sakhe sokuqala.
Indawo Yokuma (Phezulu Kwezitebhisi)
Ngokufanayo, phezulu, i-handrail kumele iqhubeke okungenani ngamasentimitha angu-305 (305 mm) ngokuvundlile ngaphezu kwekhala lesikhuphukeli saphezulu. Lokhu kwandiso kubalulekile ekuhlinzekeni ukwesekwa njengoba umsebenzisi ethatha isinyathelo sakhe sokugcina ekufikeni. Kumele iqhubeke, ngokuphakama okufanayo, endaweni yokufika eseduze uma izitebhisi ziholela kwenye indiza noma zishintsha indlela.
2. Umthetho Oqhubekayo
Phakathi kwala maphuzu, i-handrail kumele iqhubeke kuze kube yilapho izitebhisi zigijima khona, ngaphandle kokuphazamiseka yizinsika noma ezinye izithiyo.
Indlela ephephile yesandla ilandela le ndlela:
Ukufika (ukwelulwa okuvundlile okungu-12+ intshi) → Ukwehla/ukwenyuka ngethambeka lezitebhisi → Ukufika okuphansi/okuphezulu (ukwelulwa okuvundlile okungu-12+ intshi)
3. Imiphumela Ebalulekile Ewusizo
1）Ungalokothi uqale noma ume ngqo esitebhisini: Ukuqeda ngokuzumayo ireyili ekhaleni eliphezulu noma eliphansi kuwukwephulwa kwekhodi okuvamile futhi okuyingozi.
2） Xhumana nomnyango wakho wokwakha wendawo: Hlola njalo amakhodi endawo yakho kuqala, njengoba ezinye izindawo zingase zibe nezilungiso (isib., ezidinga ukunwetshwa okude).
3）Kuma-ramp: Umthetho ofanayo wokunweba ovundlile ongu-12 intshi uyasebenza phezulu nangaphansi kwama-ramp afinyelelekayo.
Ngamafuphi, i-handrail efakwe kahle ayipheli esinyathelweni sokugcina. Iqala lapho isondela ekufikeni futhi iphela ngokuphephile lapho iphuma, okuqinisekisa ukuthi ukusekelwa okuphephile nokubambayo kuhlala kufinyeleleka kuyo yonke indawo yokukhuphuka nokwehla.
