Qhov luaj li cas ntawm cov ntaiv treads yuav tsum tau yoog raws li kev ua haujlwm ntawm ko taw thiab qhov tob ntawm cov neeg laus, uas yog qhov sib txawv ntawm cov ntawv thov sib txawv thiab muaj feem xyuam rau lawv txoj haujlwm.
Qhov ntev ntawm cov treads muaj xws li qhov siab thiab qhov tob, thiab qhov sib piv ntawm qhov siab mus rau qhov tob ntawm cov treads yog txoj kab nqes ntawm cov ntaiv. Cov treads raug ntsia rau ntawm tib lub kaum sab xis kom txo qhov siab lossis nce qhov tob ntawm cov treads, thaum txuas qhov ntev ntawm cov ntaiv, thiab rov qab tuaj yeem txo qhov ntev ntawm cov ntaiv. Yuav kom txhua leej txhua tus muaj kev zoo siab thaum nce ntaiv, tus nqi ntawm cov kauj ruam tuaj yeem tswj tau hauv qhov tsim nyog.
Kev xyaum tau ua pov thawj tias qhov kev nyiam tread yog kom tsim nyog nce qhov tob ntawm cov kauj ruam thiab txo qhov siab ntawm cov kauj ruam. Yog li ntawd, thaum tsim cov ntaiv, txoj kab nqes ntawm cov ntaiv yuav tsum tau txo. Thaum taug kev, nws yuav siv zog tsawg dua li kev taug kev nrog qhov siab thiab qhov tob. Txawm li cas los xij, qhov tob yuav tsum tsis txhob me dhau, thiab nws yuav tsum tsis pub tsawg tshaj 245 mm, thiab qhov tob ntawm 245 mm yog txaus.
Lub focal point ntawm ko taw ntog ze ntawm lub pob taws, thiab pob taws kuj tuaj yeem tawm, thiab feem ntau ntawm cov focal point yog nyob ntawm lub pedal. Yog li ntawd, qhov tob ntawm cov kauj ruam ntawm cov ntaiv yuav tsum tsis pub tsawg tshaj 245 hli thiab tsis siab tshaj 300 hli. Qhov siab ntawm cov kauj ruam yuav tsum tsis pub tsawg tshaj 155 hli thiab tsis tshaj 200 hli.
Nyob rau hauv txhua ntu ntawm tib lub staircase, qhov siab thiab qhov tob ntawm cov kauj ruam yuav tsum tau ua tib yam, kom cov kauj ruam thaum nce mus rau pem hauv ntej thiab pem hauv ntej yuav zoo ib yam, thiab nws yuav tsis ua rau tib neeg tsis xis nyob.
Stairs feem ntau yuav tsum xav txog tus naj npawb ntawm cov neeg hla mus los tsim qhov dav, thiaj li ua kom cov neeg ntws mus zoo. Qhov dav ntawm cov ntaiv rau ib txoj kev yog feem ntau tsim los ntawm 600 mm lossis ntau dua, qhov dav ntawm cov ntaiv rau ob txoj kev yuav tsum tau tsim los yog 1,200 mm lossis ntau dua, thiab cov ntaiv rau cov hla dhau yuav tsum tau nce ntxiv mus. ntau tshaj 2,400 mm, kom tsis txhob muaj neeg coob coob. Thaum qhov dav ntawm cov ntaiv ntau dua 1.2 meters, nws yuav tsum tau txiav txim siab los nruab ib lub tes tuav ntawm qhov kawg ze rau ntawm phab ntsa.
Stair treads tuaj yeem ntsia tau rau ntawm cov ntaiv ntawm ntau txoj kab nqes, thiab siv nrog ntau qhov siab thiab dav specifications.
