眾所周知防火門(mén)的核心就是耐火時(shí)間，這兒的耐火時(shí)間是是指連著架構(gòu)可以滿足防火可靠性、完整性耐火性規(guī)定房門(mén)。防火門(mén)幾防火等級(jí)分甲、乙、丙三級(jí)，今天濟(jì)南防火卷簾門(mén)安裝維修人員主要介紹一下防火門(mén)的要求及其耐火時(shí)間。

As is well known, the core of fire doors is fire resistance time, which refers to the fire resistance time of the door that can meet the fire reliability, integrity, and fire resistance requirements of the connected structure. The fire resistance rating of fire doors is divided into three levels: A, B, and C. Today, the installation and maintenance personnel in Jinan mainly introduce the requirements and fire resistance time of fire doors.

The door of the room should use Class A fire doors.

防火系統(tǒng)分區(qū)消防救援窗或壁不好走道入口應(yīng)設(shè)前處理室，前處理室總面積不宜小于5m2;當(dāng)與消防電梯間合用前室時(shí)，其總面積不宜小于9m2;前處理室房門(mén)應(yīng)是甲等防火門(mén)。

當(dāng)鍋爐間內(nèi)設(shè)定儲(chǔ)油間時(shí)，其總儲(chǔ)藏量不得大于1.10m3，且儲(chǔ)油間應(yīng)使用防火墻與鍋爐間分隔;當(dāng)需要在防火墻上開(kāi)門(mén)時(shí)，應(yīng)設(shè)甲等防火門(mén)。

對(duì)防火門(mén)的相關(guān)規(guī)定還是比較嚴(yán)格，將防火門(mén)分成甲、乙二種，甲種防火門(mén)的耐火等級(jí)為1.51～2.10h。在我國(guó)甲等防火門(mén)耐火等級(jí)是1.5h，以火災(zāi)發(fā)生時(shí)避免擴(kuò)張火災(zāi)事故為主要目的。

The relevant regulations for fire doors are still quite strict, and they are divided into two types: A and B. The fire resistance rating of type A fire doors is 1.51-2.10 hours.

還是選擇高質(zhì)量的防火門(mén)，不必貪便宜，以防對(duì)咱們?cè)斐刹槐匾?jīng)濟(jì)損失，在其中甲等防火門(mén)耐火時(shí)間比較長(zhǎng)，可靠性也比較不錯(cuò)，非常大家采購(gòu)，歡迎咨詢http://luoboyy.com。

It is recommended to choose high-quality fireproof doors instead of being too cheap to avoid unnecessary economic losses. Among them, Class A fireproof doors have a longer fire resistance time and good reliability. It is highly recommended for everyone to purchase and welcome inquiries http://luoboyy.com .
