Tus Kws Kho: Saib Mate Txhua Lub Rooj Vag Iav
Cov cai teeb tsa tseem ceeb:
Cov iav txheem (dav ≤ 1.8 meters × siab ≤ 1.2 meters)
Ob lub pins rau ib lub iav vaj huam sib luag (sab saum toj / hauv qab lossis sab mounted) txaus rau thaj chaw cua tsawg.
Piv txwv li:
Ib lub vaj huam sib luag iav dav 1.2-meter → xav tau 2 tus pin.
Cov iav loj (dav > 1.8 meters lossis siab > 1.2 meters)
Yuav tsum muaj peb mus rau plaub lub pins rau ib lub iav vaj huam sib luag kom faib cov cua/cuam tshuam.
Cov vaj huam sib luag ces kaum feem ntau xav tau kev txhawb nqa ntxiv.
Cov yam tseem ceeb:
Lub zog cua (ASCE 7): Cov cheeb tsam ntug dej hiav txwv/cua hlob xav tau 50% ntau tus pin (piv txwv li, 3 tus pin rau lub vaj huam sib luag iav dav 1.5-meter).
Iav Thickness: 15mm iav tso cai rau qhov sib nrug ntau dua li 12mm iav.
Qib Kho Vajtse: ASTM F2090 cov ntsaws uas tau ntawv pov thawj txhais qhov siab tshaj plaws rau ib chav (feem ntau yog 1.2-1.8 meters).
Cov txiaj ntsig ntawm kev tsim kho tsis zoo:
Kev khoov ntawm vaj huam sib luag → kev tawg ntawm kev ntxhov siab hauv iav.
Qhov ntsaws overload → kev sib txuas tsis ua haujlwm rau iav lossis kem.
Tsis ua raws li cov cai ntawm pas dej ua ke (IBC 1607.7, AS 1926.1).
