Kho kom raug: Viewmate tag nrho cov iav railing
Lub thickness ntawm iav siv rau ntaiv (feem ntau yog raubalustrades, handrails, treads, lossis risers) tsis yog tus nqi ruaj khov - nws nyob ntawm hom iav, daim ntawv thov (cov kev cai nyab xeeb), qhov hnyav ntawm cov qauv, thiab cov cai hauv zos. Hauv qab no yog kev faib tawm ntawm cov tuab sib xws, cov kev xav tseem ceeb, thiab cov lej siv los xyuas kom muaj kev nyab xeeb thiab ua raws li txoj cai:
1. Hom Iav Tseem Ceeb rau Cov Ncej: Yuav tsum yog "Iav Kev Nyab Xeeb"
Ua ntej,txhua lub iav siv hauv cov ntaiv yuav tsum yog iav kev nyab xeeb(raws li cov cai thoob ntiaj teb ntawm lub tsev xws li US IRC, EU EN 12150, lossis Tuam Tshoj GB 15763.2). Qhov no tiv thaiv kev tawg ua tej daim me me uas muaj kev phom sij. Ob hom tseem ceeb yog:
- Iav Tempered (Iav Muaj Zog Kub): Qhov kev xaiv feem ntau - muaj zog dua li iav ib txwm muaj 5 npaug, thiab tawg ua tej daim me me, zoo li lub voos xwmfab.
- Iav Laminated: Ob lossis ntau txheej iav sib txuas nrog ib txheej polymer interlayer (piv txwv li, PVB). Txawm tias tawg lawm los, txheej interlayer tuav cov khoom seem rau hauv qhov chaw, ua rau nws zoo tagnrho rau cov chaw muaj kev pheej hmoo siab (piv txwv li, cov ntaiv, cov ntaiv sab nraum zoov).
2. Qhov tuab ntawm cov iav feem ntau yog raws li daim ntawv thov
Qhov tuab sib txawv ntau nyob ntawm seb lub iav puas siv rau ib qhobalustrade (kev tiv thaiv), tus ntaiv tes, los yogtread/riser(qhov uas nqa tau ntau dua li qhov uas tsis nqa tau ntau).
| Daim Ntawv Thov | Hom iav | Feem ntau Thickness Range | Kev Xav Tseem Ceeb |
| Stair Balustrade (Vaj Huam Sib Luag) | Tempered / Laminated | 8 hli - 12 hli | Tsis yog lub nra hnyav (tsuas yog tiv taus qhov siab ntawm sab, piv txwv li, kev nqes). 8 hli yog qhov feem ntau rau cov tsev nyob; 10–12 hli rau cov lag luam (cov neeg taug kev ntau dua). |
| Rooj vag ntaiv | Tempered / Laminated | 15 hli - 25 hli | Yuav tsum txhawb nqa tes nias (50–100N ib tus lej). Cov iav tuab dua (piv txwv li, 20mm) ua kom muaj kev ruaj khov thiab siv tau ntev. |
| Cov Ncej Ncej (Cov Kauj Ruam Iav) | Laminated (Cov Txheej Txheem Tempered) | 25mm - 40mm | Kev thauj khoomTxhawb nqa qhov hnyav ntawm tib neeg (yam tsawg kawg nkaus 500kg/m²). Feem ntau yog 2–3 txheej ntawm cov iav tempered (piv txwv li, 2x12mm + PVB = tag nrho 25mm) rau cov tsev nyob; 30–40mm rau cov lag luam. |
| Ncej Ncej (Vertical Vuas) | Tempered / Laminated | 8 hli - 10 hli | Tsis muaj lub nra hnyav (tsuas yog rau kev saib xwb). Nyias dua li cov balustrades, vim nws tsis tas yuav tiv taus lub zog sab. |
3. Cov Yam Tseem Ceeb Uas Cuam Tshuam Rau Qhov Thickness
Dhau ntawm daim ntawv thov, cov yam no yuav txiav txim siab qhov tuab kawg uas xav tau:
- Cov Cai Tsim KhoCov cai hauv zos (piv txwv li, Tebchaws MeskasCov Cai Tswjfwm Kev Nyob Thoob Ntiaj Teb (IRC), EUEN 13474) yuam kom muaj qhov tsawg kawg nkaus lub zog thiab tuab. Piv txwv li, IRC xav kom cov ntaiv ntaiv tiv taus 200 lbs (90kg) ntawm lub zog siv kab rov tav - qhov no yuav xav tau iav tuab dua rau cov balustrades siab dua.
- Span (Qhov Deb Ntawm Cov Kev Txhawb Nqa)Rau cov balustrade panels, qhov ntev dua (piv txwv li, 1.5m vs. 0.8m) xav tau iav tuab dua kom tiv thaiv kev khoov lossis tawg. Lub iav 10mm vaj huam sib luag yuav ua haujlwm rau 1m span, tab sis 1.2m span yuav xav tau 12mm.
- Cov Kev Cai Thauj KhoomCov ntaiv rau cov chaw ua lag luam (piv txwv li, cov khw loj, cov chaw ua haujlwm) xav tau cov iav tuab dua li cov ntaiv nyob hauv tsev, vim lawv yuav tsum txhawb nqa cov khoom thauj siab dua (piv txwv li, ntau tus neeg, cov khoom muaj log).
- Tej yam kev mob ib puag ncig: Cov ntaiv sab nraum zoov lossis cov ntaiv hauv cov chaw noo noo (piv txwv li, cov pas dej ua ke ze ntawm cov ntaiv) yuav siv cov iav laminated tuab dua los tiv taus huab cua thiab xeb.
4. Piv txwv cov xwm txheej
Yuav kom ua tau qhov no, ntawm no yog cov lus qhia tseeb hauv ntiaj teb tiag:
- Tsev Stair Balustrade: 10 hli tempered iav (span ≤1m, 900mm qhov siab).
- Tsev nyob iav TreadIav: 25mm laminated iav (2x12mm tempered iav + 1mm PVB interlayer).
- Kev Lag Luam Stair Handrail: 20 hli tempered iav (txhawb nqa 100N zog, 1.1m qhov siab).
- Sab nraum zoov Stair Balustrade: 12 hli laminated iav (tiv taus cua, nag, thiab kev hloov pauv kub).
5. Cov Lus Qhia Tseem Ceeb Txog Kev Nyab Xeeb
Tsis txhob siviav annealed (ib txwm)rau cov ntaiv - nws tawg ua tej daim ntse thiab txaus ntshai. Ib txwm xyuas kom meej tias lub iav tau ntawv pov thawj tias yog iav kev nyab xeeb (nrhiav cov ntawv cim zoo li "TEMPERED" lossis "LAMINATED" ntawm ntug) thiab tias qhov kev teeb tsa ua raws li cov cai hauv zos (tus kws kho vajtse lossis tus kws ua vaj tse yuav tsum paub meej qhov no).
Hauv kev xaus, qhov tuab ntawm cov iav ntaiv yog los ntawm8mm (risers / balustrades)mus rau40mm (cov khoom siv rau kev lag luam), nrog rau qhov nqi tseeb txiav txim siab los ntawm daim ntawv thov, code, span, thiab load. Ib txwm muab qhov tseem ceeb rau iav kev nyab xeeb thiab kev ua raws li cov cai hauv zos.
