Tus Kws Kho: Saib Mate Txhua Lub Rooj Vag Iav
Cov yam tseem ceeb uas ua raws li txoj cai rau cov iav thaiv (daim ntawv thov rau ntawm lub lawj, ntaiv, lossis pas dej):
1. Lub Peev Xwm Thauj Khoom ntawm Cov Qauv (Tsis Sib Tham Tau)
-Kev Tiv Thaiv Kev Thauj Khoom Nyob:
A 200-phauskev thauj khoom uas muaj zogsiv kab rov tav ntawm txhua qhov chaw (IBC 1607.7.1).
Akev thauj khoom sib xws ntawm 50 phaus ib ko taw linearhlasab saum tojntug (ASCE 7-22).
Kev Txwv Kev Tig:Txwv rau L/60 (piv txwv li, siab tshaj plaws ntawm 1 nti rau qhov ntev 5-foot) thaum thauj khoom.
Kev Ntsuas Txheem:ASTM E2353 (yuav tsum muaj daim ntawv pov thawj los ntawm lwm tus).
2. Khoom Siv & Kev Tsim KhoomCov Lus Qhia Tshwj Xeeb
| Cheebtsam | Qhov Yuav Tsum Tau Ua |
| Hom iav | Tempered (ASTM C1048) los yog laminated tempered (ANSI Z97.1) -tsawg kawg nkaus 12 hli tuab. |
| Kho vajtse | 316 stainless hlau qib marine (ASTM F2090); txhuas alloy 6061-T6. |
| Ntug tiav | Cov npoo uas tau sib txuas/txhuam tiav lawm (tsis muaj qhov ntse raws li CPSC 16 CFR 1201). |
| Kev Nyab Xeeb Txog Kev Cuam Tshuam | Yuav tsum dhau qhov kev xeem pob zeb 100 hli (tsis muaj qhov sib txawv > 4″) kom tiv thaiv menyuam yaus kom tsis txhob raug ntes (IBC 1015.3). |
Qhov Siab ntawm Guardrail:
- Cov chaw nyob hauv tsev:36–42 ntiv tes (IBC 1015.2).
- Lag luam/ntaiv:Yam tsawg kawg yog 42 nti (ADA 505.4).
-Cov Kev Cai Tsheb Ciav Hlau Sab Saum Toj:
- Cov Ncej:Yuav tsum muaj ib txoj hlua khi sab saud uas tuav tau, qhov siab 34–38 ntiv tes, (IBC 1014.6).
- Cov leveling decks:Ib txoj hlua sab saud yog xaiv tau yog tias lub iav ua tau raws li qhov siab thiab qhov hnyav.
- Cov Khoom Txuas Hauv Paus:
- Cov ntsia hlau txuas uas muaj qhov tsawg kawg yog 1/2 nti, teeb rau hauv cov pob zeb ua vaj tse nrog epoxy (tsawg kawg yog 3-nti embedment).
4. Cov Ntaub Ntawv Tshwj Xeeb: Stair Iav Guardrails
-Kev Sib Txuas Tes Tuav:Iav tsis tuaj yeem ua tus ntaiv tes; xav tau ib tus ntaiv sib cais uas tuav tau.
- Kev Sib Txuas ntawm Cov Log Tsheb:Utilize countersunk taub hau pinsnrog UV-ruaj khov epoxy (piv txwv li, SikaFlex® 295).
- Phaj Kick:Yuav tsum muaj qhov siab tsawg kawg yog 4 ntiv tes ntawm lub hauv paus ntaiv kom tiv thaiv kev plam ko taw (OSHA 1910.29).
5. Cov Ntsiab Lus Ua Tsis Tau Zoo Feem Ntau
- "80% ntawm kev tshuaj xyuas tsis ua tiav suav nrog:
- Cov iav uas tsis tau ntawv pov thawj (siv 10 hli annealed es tsis yog 12 hli tempered)
- Qhov sib txawv > ntau dua 100 hli ntawm cov vaj huam sib luag
- Cov khoom siv hlau tsis xeb 304 uas xeb hauv thaj chaw ntug dej hiav txwv
- Tsis muaj cov ntawv qhia txog kev sim thauj khoom ntawm lwm tus neeg.
Cov Lus Qhia Los Ntawm Cov Kws Tshaj Lij
-Rau cov chaw muaj neeg coob coob:Siv 15 hli laminated iav nrog 1.52 hli PVB interlayer.
- Cov cheeb tsam cua:Txo qhov sib nrug ntawm lub qhov (spigot spacing) kom tsawg dua 1.2 meters (ASCE 7 wind maps).
-Cov ntaub ntawv pov thawj:Khaws cov ntawv pov thawj ntawm lub Hoobkas (rau iav) thiab ASTM F2452 (rau cov khoom siv kho vajtse).
- Ib txwm xa cov duab kos engineering kom tau txais kev pom zoo.Cov kev teeb tsa uas tsis ua raws li txoj cai yuav raug nplua ntau tshaj $ 5,000 thiab tej zaum yuav ua rau kev pov hwm tsis muaj txiaj ntsig.
