Lub qhov rooj iav qhov hluav taws kub yog dab tsi?
Lub qhov rooj iav uas tiv thaiv hluav taws kub yog qhov yuav tsum tau sib cais hluav taws. Ua raws li cov qauv hauv tebchaws tam sim no GB12955-2024 《Fire Resistant Doors》, GB50016 《Code for Fire-Protection Design of Buildings》and GB15763.1 》Fire-Resistant Glass express, nws yog assembled los ntawm hlau qhov rooj ntas, fire-resistant iav, tshwj xeeb purse-sensescent fire-poses hluav taws-resistant filling cov ntaub ntawv.
Muab piv nrog cov hlau zoo tib yam thiab cov qhov rooj ntoo uas muaj hluav taws kub, nws ua ke nrog kev sib cais ntawm cov pa taws thiab hluav taws, kev nyab xeeb khiav tawm, teeb pom kev zoo sab hauv tsev, pom qhov pom tseeb thiab zoo nkauj zoo nkauj. Niaj hnub no, nws tau dhau los ua cov khoom siv hluav taws xob muaj kev nyab xeeb rau cov khw muag khoom, cov tsev ua haujlwm, tsev kho mob, chaw nres tsheb hauv av, chaw ua haujlwm hauv tsev thiab cov khoom siv hauv tsev.
qhov ntsuas hluav taws kub tsis kam thiab hom iav
Paub qhov txawv ntawm qhov chaw teeb tsa ua ntej. Class-C monolithic fire-resistant iav qhov rooj yuav tsum tsis txhob raug coj mus rau kev khiav tawm.
Class-A1.50 (Qib-A, 90-feeb hluav taws tsis kam; Class-A kub-insulated hluav taws kub-resistant iav Ntau dua los yog sib npaug rau 35 hli) Daim ntawv thov qhov chaw: chav faib hluav taws xob, chav tswj hluav taws kub, lub tsev twj tso kua mis, qhib rau ntawm phab ntsa hluav taws kub, cov chaw cia khoom phom sij thiab cov cuab yeej siv tshuab. Yuav tsum tau yuav tsum tau: grouted composite tshav kub-insulated fire-resistant iav. Nws thaiv cov hluav taws kub kub hauv qhov hluav taws kub thiab tiv thaiv cov hluav taws kub hnyiab ntawm sab uas tsis muaj hluav taws xob los ntawm hluav taws kub.
Class-A1.00 (Qib-B, 60-feeb hluav taws kub tsis kam; Class-A hluav taws kub-resistant iav Ntau dua los yog sib npaug li 25 hli) Cov lus qhia dav dav tshaj plaws hauv kev tsim kho. Haum rau stair vestibules, corridors, shop partitions, mall walkways, underground evacuation exits and access doors for underground parking lots. Nws muab kev nkag mus rau nruab hnub nrig rau kev siv txhua hnub nrog rau cov pa taws thiab hluav taws kub rwb thaiv tsev thaum hluav taws kub. Qib-B hom insulated cua sov yog qhov kev xaiv tseem ceeb tshaj plaws rau feem ntau cov chaw nkag mus rau pej xeem.
Class-A0.50 (Qib-C, 30-feeb hluav taws tsis kam) Siv rau cov qhov rooj nkag mus rau cable shafts, piping shafts thiab ventilation shafts, nrog ib tug compact-loj iav saib qhov rais txais tau.
Class-C monolithic caesium-potassium hluav taws-resistant iav qhov rooj (tsuas yog hluav taws kev ncaj ncees muab, tsis muaj cua sov-insulating kev ua tau zoo) Tso cai rau sab nrauv-phab ntsa nruab hnub-hloov partitions thiab tsis-evacuation zoo nkauj sab hauv partitions. Kev yuav khoom yog txwv tsis pub rau cov stairwells, txoj kev khiav tawm thiab txhua txoj kev uas tib neeg siv tsis tu ncua.
Txoj cai xaiv nyuaj-thiab-ceev ceev: tsuas yog Class-A cov khoom siv hluav taws kub-insulated iav qhov rooj tuaj yeem ntsia tau rau ntawm txhua qhov rooj ntawm txoj kev khiav.
