防火卷簾設置要求都在這里!
一、一般規定
1、 General regulations
防火分隔部位設置防火卷簾時,應符合下列規定:
When installing fire resistant rolling shutters in the fire separation area, the following regulations should be met:
1.除中庭外,當防火分隔部位的寬度≤30m時,防火卷簾的寬度應≤10m;當防火分隔部位的寬度>30m時,防火卷簾的寬度應≤該部位寬度的1/3,且應≤20m。
1. Except for the courtyard, when the width of the fireproof partition area is ≤ 30m, the width of the fireproof roller shutter should be ≤ 10m; When the width of the fireproof partition area is greater than 30m, the width of the fireproof roller shutter should be ≤ 1/3 of the width of the area and ≤ 20m.
解釋:這條規范不包含中庭即,中庭部分防火分隔用的防火卷簾,其寬度沒有限制!!!
Explanation: This regulation does not include the fire resistant rolling shutters used for fire separation in the atrium, and their width is not limited!!!
另外,30m作為分界線。當需要防火分隔的部分其寬度>30m時,設為D,即防火卷簾的寬度在1/3D和20之間取小
Additionally, 30m serves as the dividing line. When the width of the part that requires fire separation is greater than 30m, set it to D, that is, the width of the fire shutter should be smaller between 1/3D and 20
2.防火卷簾應具有火災時靠自重自動關閉功能;不應采用水平、側向防火卷簾。
2. The fireproof roller shutter should have the function of automatically closing by its own weight in case of fire; Horizontal and lateral fire resistant rolling shutters should not be used.
3.除規范另有規定外,防火卷簾的耐火極限不應低于規范對所設置部位墻體的耐火極限要求。
3. Unless otherwise specified in the specifications, the fire resistance limit of the fire resistant roller shutter should not be lower than the fire resistance limit requirements of the wall in the set position specified in the specifications.
4.當防火卷簾的耐火極限符合現行標準《門和卷簾的耐火試驗方法》GB/T7633有關耐火完整性和耐火隔熱性的判定條件時,可不設置自動噴水滅火系統保護。當防火卷簾的耐火極限僅符合現行標準《門和卷簾的耐火試驗方法》GB/T7633有關耐火完整性的判定條件時,應設置自動噴水滅火系統保護。自動噴水滅火系統的設計應符合現行標準《自動噴水滅火系統設計規范》GB50084的規定,但火災延續時間不應小于該防火卷簾的耐火極限。
When the fire resistance limit of fire resistant rolling shutters meets the criteria for determining fire resistance integrity and thermal insulation in accordance with the current national standard "Fire resistance test methods for doors and rolling shutters" GB/T7633, automatic sprinkler system protection may not be installed. When the fire resistance limit of fire resistant rolling shutters only meets the criteria for determining fire resistance integrity in the current national standard "Fire resistance test methods for doors and rolling shutters" GB/T7633, an automatic sprinkler fire extinguishing system should be installed for protection. The design of automatic sprinkler systems should comply with the current national standard "Code for Design of Automatic Sprinkler Systems" GB50084, but the fire duration should not be less than the fire resistance limit of the fire shutter.
將3與4條,放到一起解釋:
Put 3 and 4 together to explain:
舉例,多層煤粉廠房,二級耐火等級,每層采用防火墻劃分若干個防火分區,防火分隔部位寬度為27m,由于工藝要求,防火墻上設置防火卷簾。
For example, a multi-layer coal powder plant has a secondary fire resistance rating, and each floor is divided into several fire compartments using a firewall. The width of the fire compartment is 27m. Due to process requirements, fire rolling shutters are installed on the firewall.
則該非隔熱性防火卷簾應如何設置?
How should the non thermal insulation fireproof roller shutter be set?
第3條說的是防火卷簾的耐火極限要與它所在的墻體的耐火極限一樣。
Article 3 states that the fire resistance limit of the fireproof roller shutter should be the same as the fire resistance limit of the wall it is located on.
第4條說的是防火卷簾是否需要設置自噴系統保護的問題。
Article 4 discusses the issue of whether a self spraying system needs to be installed for protection of fireproof rolling shutters.
如果防火卷簾既有耐火完整性又有耐火隔熱性,可不設自噴保護;若只有耐火完整性,應設自噴保護。
If the fireproof roller shutter has both fire resistance integrity and fire insulation, it may not be equipped with self spraying protection; If there is only fire resistance integrity, self spraying protection should be installed.
