Tus Kws Kho: Saib Mate Txhua Lub Rooj Vag Iav
Cov Kev Cai Rau Kev Tiv Thaiv Iav: Daim Ntawv Teev Cov Cai Ua Raws Cai (2024 IBC/ADA/ASCE)
1. Cov Khoom Siv
-Iav:
Tempered los yog Laminated Tempered (ASTM C1048 / ANSI Z97.1)
Yam tsawg kawg nkaus Thickness: 12mm (tsev nyob), 15mm+ (lag luam/cua hlob)
-Khoom siv kho vajtse:
316 Cov Hlau Stainless Qib Marine (ASTM F2090)
Cov hlua khi epoxy (ua los ntawm pob zeb ua vaj tse) los yog cov hlua khi through-bolts (ntoo)
2. Cov Qauv Kev Tsim Kho thiab Kev Nyab Xeeb
| Qhov Yuav Tsum Tau Ua | Cov lej siv rau kev siv | Kev Qhia Txog Kev Siv Tshuab |
|---|---|---|
| Kev Thauj Khoom Uas Muaj Zog | IBC 1607.7.1 | 200 lbs ntawm txhua lub sijhawm |
| Kev Txwv Tsis Pub Txav Mus Los | ASCE 7-22 | ≤ L/60 (piv txwv li, 1″ siab tshaj plaws rau 5ft span) |
| Qhov Siab (Nyob Hauv Tsev) | IBC 1015.2 | 36″–42″ saum qhov chaw taug kev |
| Qhov Siab (Lag Luam/Ncej) | ADA 505.4 | tsawg kawg 42″ |
| Kev Txwv Qhov Sib Txawv | IBC 1015.3 | ≤100mm (4 ") kev xeem pob kheej |
| Rooj vag sab saum toj (Tsuas yog ntaiv xwb) | IBC 1014.6 | Txoj kev tuav tau 34–38″ qhov siab |
3. Cov Txheej Txheem Tseem Ceeb rau Kev Teeb Tsa
Kev Kho Ntug: Cov npoo uas tau txhuam/seamed (CPSC 16 CFR 1201)
Kev khi:
Pob zeb ua vaj tse: 1/2″ epoxy anchors (3″ embedment)
Ntoo: 3/8″ through-bolts nrog cov phaj thaub qab
Qhov Sib Nrug Ntawm Lub Qhov Rooj: ≤1.5m (4.9 ft) rau 12 hli iav (ASCE 7 daim ntawv qhia cua)
Cov Ntaub Ntawv: Yuav tsum muaj cov ntawv qhia txog kev sim khoom ntawm ASTM E2353 sab nraud
4. Cov Ntsiab Lus Ua Tsis Tau Zoo thiab Kev Kho
- ❌ 10 hli iav annealed → Hloov nrog 12 hli+ tempered
- ❌ 304 stainless hlau kho vajtse → Hloov kho mus rau 316 SS nrog ASTM F2090 daim ntawv pov thawj
- ❌ Qhov sib txawv >100 hli → Kho cov clamps/spigots
- ❌ Tsis muaj tus ntaiv sab saud → Nruab tus ntaiv uas tuav tau (qhov siab 34–38″)
"Xyoo 2023 cov ntawv qhia txog kev raug mob qhia tias 72% ntawm kev ua tsis tiav yog vim muaj iav tsis tau ntawv pov thawj lossis cov khoom siv xeb."
— Pawg Neeg Saib Xyuas Kev Nyab Xeeb Hauv Tebchaws (NSC) Ceeb Toom
5. Cov Lus Qhia Los Ntawm Cov Kws Tshaj Lij
- Cov Cheeb Tsam Cua Hnyav: Siv 15 hli iav laminated + 50% ntxiv cov anchors
- Cov Chaw Ntug Dej Hiav Txwv: Qhia meej cov hlau tsis xeb 316L (tsis muaj ntsev)
- Cov Ncej: Siv cov ntsia hlau uas muaj lub hau countersunk nrog cov epoxy uas tiv taus UV (SikaFlex® 295) los sib txuas ua ke.
- Kev Pom Zoo Ua Ntej ntawm Chaw Tsim Khoom: Cov Txheej Txheem zoo liQ-Railinglos yogCR Laurencesuav nrog cov pob khoom ua raws li txoj cai
⚠️ Lus Cim Txog Kev Nplua: Kev teeb tsa uas tsis ua raws li txoj cai yuav raug nplua $ 5,000+ (Tebchaws Meskas) thiab tsis muaj kev pov hwm.
