Qhov no framing style yog hu ua ncej thiab beam, thiab lub overhang yog ib cantilever.

Ib yam li ntawd, tej zaum koj yuav nug, yuav ua li cas deb ntawm lub lawj tuaj yeem cantilevered?

Joist Cantilevers Raws li cov ntxhuav ncua tshiab thiab IRC cov cai, cantilevers tau ncua mus txog ib feem plaub ntawm backspan ntawm lub joist. Qhov no txhais tau hais tias joists, xws li yav qab teb ntoo thuv 2x10s ntawm 16 ntiv tes nyob rau hauv nruab nrab, spanning 12 ko taw tau tso cai rau cantilever mus txog 3 ko taw ntxiv (saib daim duab, hauv qab).

koj puas tuaj yeem tau txais lub lawj beam? American Wood Council's Wood Frame Construction Manual hais tias kab teeb tau feem ntau cantilever mus txog 1/4 lawv ncua dhau ib qho ncej. Cov qauv tsim no feem ntau txwv rau kab teeb txhawb sib npaug joist lengths nyob rau hauv nws span raws li nyob rau hauv nws cov cantilevered seem.

Ua qhov no hauv kev txiav txim siab, lub hom phiaj ntawm cantilever yog dab tsi?

Cantilevers muab qhov chaw ntshiab nyob hauv qab ntawm kab teeb yam tsis muaj kev txhawb nqa kab lossis kev sib khi. Cantilevers tau los ua ib qho kev tsim qauv nrov nrog kev taw qhia ntawm cov hlau thiab cov pob zeb muaj zog. Lawv tau siv dav hauv kev tsim vaj tsev, tshwj xeeb hauv: Cantilever choj. Hloov pauv cov ntsiab lus thiab kev kwv yees.

Ntev npaum li cas koj tuaj yeem cantilever 2x8 lawj joist?

Yog txoj cai ncua cov ntxhuav tso cai rau a 2 x8x mus span 12 feet, ces tus cantilever tau ua 3fti.
