Fire-Rated Security Entrance Door Technical Analysis Mandarin Oriental Hotel
Lub qhov rooj nkag mus rau qhov hluav taws kub yog lub hom phiaj tshwj xeeb rau kev nkag qhov rooj uas ua tau raws li ob pawg ntawm cov qauv tsim nyog hauv lub tebchaws rau kev tiv thaiv hluav taws thiab tiv thaiv tub sab. Qhov sib txawv ntawm cov qhov rooj hluav taws kub zoo tib yam thiab qhov rooj ruaj ntseg zoo tib yam, cov khoom siv no sib xyaw ua ke ob txoj haujlwm ntawm hluav taws kub & pa taws ntim thiab prying-resistant tiv thaiv kev quab yuam nkag. Nws yog dav siv rau qhov chaw nkag ntawm cov tsev nyob siab, cov tsev, tsev so thiab cov vaj tsev sib xyaw ua lag luam-chaw nyob, ua ib feem tseem ceeb rau kev ruaj ntseg hauv tsev thiab hluav taws kub.
Hauv kev coj ua engineering, muaj qhov tsis sib xws xws li kev txhais lus tsis raug ntawm cov qauv, cov khoom txiav cov ces kaum thiab daim ntawv pov thawj tsis raug siv feem ntau ua rau tsis ua tiav hauv kev lees txais hluav taws kub. Yog li ntawd, kev nkag siab txog nws cov qauv tsim, cov kev tsis sib xws nrog rau kev teeb tsa thiab kev lees paub yog qhov tseem ceeb rau kev ua tiav qhov project.
Hlau daim hlau: Nominal thickness ntawm lub qhov rooj ncej steel phaj siab dua los yog sib npaug rau 1.2 hli; qhov rooj nplooj nplooj phaj siab dua los yog sib npaug li 0.8 hli.
Qhov rooj nplooj ntoos core filling: Lub qhov rooj nplooj yuav tsum tau ntim nrog Class-A uas tsis yog-combustible high-density perlite hluav taws-resistant core board
Intumescent hluav taws-sealing strips: Intumescent hluav taws-sealing strips nyob ib ncig ntawm lub qhov rooj ncej, expansion ratio Ntau tshaj los yog sib npaug rau 5 ×. Ntau dua lossis sib npaug li 5 npaug.
Tshwj xeeb lub hom phiaj kho vajtse system: Hluav taws xob ntsuas kev ruaj ntseg xauv; tsis pub tsawg tshaj 3 teev hluav taws kub hinges.
Key Performance Indicators
Kev Ua Haujlwm Hluav Taws Xob
A1.0: Kev ruaj ntseg hluav taws kub thiab rwb thaiv tsev Ntau dua los yog sib npaug li 60 min (sib npaug rau Qib-B qhov hluav taws kub ntsuas raws li tus qauv qub, feem ntau siv rau cov tsev nyob siab). A1.5: Kev ruaj ntseg hluav taws kub thiab rwb thaiv tsev Ntau dua lossis sib npaug li 90 min (sib npaug rau Qib-A qhov hluav taws kub-rated qhov rooj raws li tus qauv qub, yuav tsum muaj rau cov tsev nyob tshaj 54 m).
Kev tiv thaiv kev ua txhaum cai (GB17565-2022)
Qib 3: Kev quab yuam nkag siab ntau dua lossis sib npaug li 10 min. Qib 4: Kev quab yuam nkag siab dua lossis sib npaug li 15 feeb. Qib 5: Kev quab yuam nkag siab dua lossis sib npaug li 30 min; anti-pick resistance Ntau dua los yog sib npaug li 15 min. Qib 4 & 5 tau txais kev pom zoo rau cov phiaj xwm nkag siab.
Cov Khoom Siv Tseem Ceeb & Cov Qauv Txheej Txheem
Hlau Phaj: Nominal thickness ntawm qhov rooj-ncej steel phaj siab dua los yog sib npaug rau 1.2 hli; Qhov rooj-nplooj nplooj phaj siab dua lossis sib npaug ntawm 0.8 hli, Q235 / Q345B steel. Kev ntsuas ntawm qhov chaw vernier-caliper raug pom zoo kom tsis txhob muaj qhov tsis tseeb-tshwj xeeb tuab thiab cov khoom skimping.
Qhov Rooj-nplooj Core Filling: Lub qhov rooj nplooj yuav tsum tau ntim nrog Class-A uas tsis yog-combustible high-density perlite hluav taws-resistant core board. Honeycomb daim ntawv lossis pob zeb zoo tib yam yog txwv tsis pub hloov. Core filling yuav tsum compact yam tsis muaj qhov hollow; tsis muaj hollow suab thaum tapping lub qhov rooj nplooj.
