Ntoo fireproof qhov rooj kuj yog ib feem tseem ceeb rau txhua yam ntawm tej yaam num xws li kev tos txais zoo li tsev so, chaw so, chaw nyob, lossis tsev lag luam xws li tsoomfwv lossis chaw ua haujlwm ntiag tug thiab lwm yam. Hauv qab no yog cov qauv ntxhib rau siv.
1. Kev faib tawm (Core hauv paus: Kev ntsuas hluav taws kub):
- Chav Kawm A qhov rooj hluav taws: Kev ntsuas hluav taws kub ntau dua lossis sib npaug li 1.50 teev. Qhov no yog qib siab tshaj ntawm qhov rooj hluav taws.
- Chav Kawm B qhov rooj hluav taws: Kev ntsuas hluav taws kub ntau dua lossis sib npaug li 1.00 teev. Qhov no yog ib qho ntawm cov qib uas feem ntau siv.
- Class C hluav taws qhov rooj: Kev ntsuas hluav taws kub ntau dua lossis sib npaug li 0.50 teev. Feem ntau yog siv nyob rau hauv cov cheeb tsam uas yuav tsum tau qis dua.
2. Daim Ntawv Thov Scenario (raws li "Code for Fire Protection Design of Buildings" GB50016):
- Class A hluav taws qhov rooj:
Cov qhov rooj tau teeb tsa ntawm hluav taws-cov khoom tiv thaiv los yog cov phab ntsa hluav taws xob (xws li kev faib tawm ntawm qhov sib txawv ntawm qhov hluav taws kub hauv tsev so, cov qhov rooj ua los ntawm cov khoom siv tseem ceeb xws li chav twj tua hluav taws thiab chav faib hluav taws xob mus rau txoj kev hauv tsev).
Cov qhov rooj tau nruab rau hauv txoj kev khiav tawm ntawm qhov chaw hluav taws kub.
Qhov rooj ntawm cov pa luam yeeb- pov thawj stairwells thiab lawv cov chav hauv siab -cov tsev nce siab (feem ntau yuav tsum tau Chav A).
Qhov rooj ntawm qhov hluav taws kub of elevator anterooms (feem ntau yuav tsum tau Class A).
Kev tshuaj xyuas lub qhov rooj ntawm cov ncej ntsug xws li cable shafts, yeeb nkab shafts, pa luam yeeb ducts, thiab khib nyiab chutes (yog hais tias qhov hluav taws kub tiv thaiv ntawm phab ntsa ncej yog siab dua los yog sib npaug li 1.00h, Class C qhov rooj yuav tsum tau siv; txwv tsis pub, Class A qhov rooj yuav tsum tau).
- Class B hluav taws qhov rooj:
Qhov rooj ntawm cov stairwells uas nyob ib puag ncig (tsis yog- siab- nce lossis qee qhov xwm txheej).
Qhov rooj ua rau cov staircases sab nraum zoov.
Qhov rooj nruab nrab ntawm cov chav thiab kev khiav tawm txoj hauv kev (xws li lub tsev so qhua chav qhov rooj ua rau txoj kev hauv tsev, tsev noj mov chav tsev qhov rooj, thiab lwm yam). Qhov no yog hom hluav taws kub tshaj plaws hauv tsev so.
Cov qhov rooj ntawm lub qhov rooj (xws li cov pa luam yeeb-cov pov thawj stairwell anterooms, hluav taws of elevator anterooms, thiab cov chav tsev sib koom) mus rau kev khiav tawm txoj hauv kev (qee zaum yuav yog ib chav sib txawv dua li lub qhov rooj stairwell).
Qhov rooj ntawm qhov cua thiab cov khoom siv cua txias chav (thaum qhib rau hauv lub tsev).
- Class C hluav taws qhov rooj:
Kev tshuaj xyuas lub qhov rooj ntawm cov ncej ntsug xws li cable shafts, yeeb nkab shafts, pa taws tso pa, thiab khib nyiab chutes (thaum qhov ntsuas hluav taws kub ntawm cov ncej phab ntsa yog ntau dua lossis sib npaug li 1.00h).
Qhov rooj ntawm cov khoom siv chav nyob hauv cov chaw uas tsis yog - muaj neeg coob coob ntawm cov tsev (xws li cov chav tsis yog -tseem ceeb) (raws li cov cai tshwj xeeb).
3. Cov khoom siv:
Cov qhov rooj hluav taws feem ntau yog cais los ntawm cov khoom siv rau hauv:
- Cov qhov rooj hluav taws kub hlau: Hom ntau tshaj plaws. Lub qhov rooj thiab lub qhov rooj nplooj ncej yog ua los ntawm txias- dov steel phaj, thiab sab hauv yog ntim nrog hluav taws kub- tiv taus thiab kub- cov ntaub ntawv insulating (xws li perlite board). Ntoo Hluav Taws Qhov Rooj: Lub qhov rooj thiab lub qhov rooj nplooj ncej yog ua los ntawm cov nplaim hluav taws- cov khoom siv hluav taws xob los yog cov nplaim hluav taws- cov khoom siv hluav taws xob tsis zoo, thiab sab hauv muaj hluav taws kub - tiv taus thiab kub- cov ntaub ntawv insulating. Lawv yuav tsum tau txais cov nplaim taws tshwj xeeb- kev kho mob retardant thiab ua tau raws li qhov yuav tsum tau muaj kev ntsuas hluav taws kub sib xws.
- Hlau- Ntoo Hluav Taws Qhov Rooj: Lub qhov rooj ncej yog ua los ntawm steel, thiab lub qhov rooj nplooj ncej yog ua los ntawm cov nplaim hluav taws- retardant ntoo los yog nplaim hluav taws- cov khoom siv ntoo retardant, los yog lub qhov rooj ncej yog ua los ntawm cov ntoo / nplaim hluav taws- cov ntaub ntawv ntoo retardant, thiab lub qhov rooj nplooj ntawv yog ua los ntawm steel.
- Qhov Rooj Hluav Taws Xob ntawm Lwm Cov Khoom Siv: Xws li cov hlau tsis muaj steel thiab iav qhov rooj hluav taws (uas yuav tsum ua kom tau raws li kev ncaj ncees thiab kev rwb thaiv tsev). Tsis hais txog ntawm cov khoom siv, lawv yuav tsum xeem dhau lub teb chaws muaj ntawv pov thawj hom kev xeem thiab ua tau raws li cov qauv ntsuas hluav taws xob sib xws.
4. Cov ntsiab lus tseem ceeb:
- Tsis Siv Neeg Kaw: Cov qhov rooj hluav taws feem ntau yuav tsum tau nruab nrog lub qhov rooj kaw kom ntseeg tau tias tsis siv neeg kaw thaum muaj hluav taws (feem ntau qhib qhov rooj hluav taws yuav tsum muaj hluav taws xob tso tawm hluav taws xob kaw thaum muaj hluav taws kub).
- Kev sib khi: Yuav tsum muaj hluav taws kub zoo- cov hlua khi tiv taus (xws li cov hlua khi intumescent) ntawm lub qhov rooj thiab lub qhov rooj ncej, thiab nruab nrab ntawm lub qhov rooj nplooj (rau ob lub qhov rooj), uas nthuav dav thaum cua sov los kaw qhov khoob.
- Sequence Closer: Muab ob npaug los yog ntau- nplooj hluav taws qhov rooj yuav tsum tau nruab nrog ib ntu los ze zog kom ntseeg tau tias lawv kaw kom raug.
- Kev Kos Npe: Cov qhov rooj hluav taws yuav tsum muaj daim ntawv teev npe tas mus li qhia cov chaw tsim khoom, cov khoom npe, cov qauv tshwj xeeb, kev ntsuas hluav taws kub, thiab cov qauv siv tau.
