Tus Kws Kho: Saib Mate Txhua Lub Rooj Vag Iav
Qhov sib nrug ntawm cov iav latches (brackets) kom raug yog qhov tseem ceeb rau kev ruaj khov ntawm lub laj kab pas dej tsis muaj thav duab. Cov qauv kev lag luam teev tseg:
Cov Lus Qhia Tseem Ceeb Txog Kev Sib Nrug:
Qhov Sib Nrug Txheem:
Cov Ncej Ntsug: Cov pins raws cov ncej feem ntau yog sib nrug 4-6 feet (1.2-1.8 meters) sib nrug.
Hauv Qab Channel: Cov channel txuas ntxiv tshem tawm qhov xav tau cov latches nruab nrab.
Cov Yam Tseem Ceeb Uas Yuav Tsum Tau Txiav Txim Siab:
Iav Thickness: 12mm iav tuaj yeem sib nrug ntau dua li cov vaj huam sib luag nyias dua.
Qhov Siab Vaj Huam Sib Luag: Cov vaj huam sib luag siab dua (dhau 1.2 meters) xav tau qhov sib nrug ze dua (tsawg dua 1.5 meters).
Huab Cua Loj: Cov cheeb tsam cua hlob (tus qauv ASCE 7) xav tau lub sijhawm luv dua.
Cov Khoom Siv Kho Vajtse: ASTM F2090 cov ntsaws uas tau ntawv pov thawj txhais tau tias muaj peev xwm thauj khoom siab tshaj plaws rau ib chav.
Cov txiaj ntsig ntawm qhov chaw tsis raug:
Qhov ntev tshaj 1.8 meters tuaj yeem ua rau iav puas thiab ua rau cov kab nrib pleb tshwm sim hauv kev sib tsoo.
Kev co ntau dhau thaum muaj cua hlob tuaj yeem ua rau cov pob qij txha puas tsuaj.
Tsis ua raws li cov qauv thaiv pas dej ua ke (piv txwv li IBC 1607.7).
