Yog li ntawd, yuav ua li cas nyob deb ntawm ib tug joist cantilever?

Joist Cantilever Raws li cov rooj sib tham tshiab thiab IRC cov kev cai, cantilever tuaj yeem txuas mus txog ib feem plaub ntawm lub backspan ntawm lub joist . Qhov no txhais tau tias joists , xws li cov ntoo thuv sab qab teb 2x10s ntawm 16 ntiv tes rau hauv nruab nrab, ncua 12 ko taw tau tso cai rau cantilever mus txog 3 ko taw ntxiv (saib daim duab, hauv qab).

Qhov thib ob, koj tuaj yeem ua tau ntev npaum li cas ntawm 2x6 joist? Saib ntawm lub rooj hauv qab no, peb saib ntawd 2x6 ua pem teb joists tau yuav cantilevered mus txog 2 ko taw thiab 6 ntiv tes (2'-6 ") thaum lub joists yog spaced 16 "sib nrug.
