canlilevered/floating stair

mga kacgp meron po ba kayong detailed drawing ng cantilevered stair.Thanks for advance.

what do you mean cantilevered stair? ..materials ( wood, steel, concrete)? stairs itself when no supporting post is cantilevered already.

concrete stair details:

just like this one sir.

for concrete its not possible unless you make the steps a bit larger, and or provide a cable on steps end connected on the second floor slab. if its steel structure, i think much better - steel steps connected on steel stair girder - use inverted channel

Ang secret lang dyan is maganda ang pagkabaon mo ng timber. It shoud be a solid wood inserted into a shear wall or a stair beam/diagonal beam.

another approach is kung fake wood ka lang, meaning thin planks lang, magpausli ka ng steel stairs, tapos balutan mo ng thin wood planks.

Pwede din layers of glass ang gamitin dito.

Ang nanotice ko lang dito, dapat magaling ang gagawa. Kasi nag-attempt na kami ng ganito dati, pero walang budget, hirap gayahin.

Anyway, dapat ipadetalye sa engineer ang structural component nyan, kasi architecturally, it works and it's easy. Good luck!

make beam running at the wall where you expect the tread to meet it. to provide a better moment reistance kabitan mo ng steel plates ang beam then lay on top yung treads mo, then make sure tge bottom is clean, the steel plates should me embedded then apply laminates under, alam na ng carpenter ang gagawin later

Thanks bro.

Meron pa akong isang naisip dito. Insted of steel beam, ok din kahit mga angle bars or nakavertical na flat bars. Tapos i-fill in lang ang gaps + top and bottom ng wood. Mas less ang bending. Siguro mga 4-6 na flat or angle bars per thread. Cheaper pa ang labas.

Pwede din siguro solid wood dito pero kailangan may nakalabas steel reinforcement bars na malaki, around 25mm dia pataas, then may hole yung solid wood steps tapos insert mo nalang,

kadalasan meron talagang naka embed na diagonal I-beam sa wall as stringer ng stair at saka meron na itong T- bar welded and serve as threads' support and duon ikabit yung mga threads na may cut o channel at simply iscrew na lang sa bottom...at kung naka hide naman ang mga support na bakal, make a hole channel sa gitna ng thread para pasukan ng round bar ilalag bolt at saka ipla-plug yung butas para matakpan ang mga ulo ng bolts para sa finish look...labor intensive ito kung manumanuhin kaya sa prefab na lang
