防火卷帘设置要求都在这里！

1、 General regulations

防火分隔部位设置防火卷帘时，应符合下列规定：

When installing fire resistant rolling shutters in the fire separation area, the following regulations should be met:

1.除中庭外，当防火分隔部位的宽度≤30m时，防火卷帘的宽度应≤10m；当防火分隔部位的宽度＞30m时，防火卷帘的宽度应≤该部位宽度的1/3，且应≤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.

解释：这条规范不包含中庭即，中庭部分防火分隔用的防火卷帘，其宽度没有限制！！！

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作为分界线。当需要防火分隔的部分其宽度＞30m时，设为D，即防火卷帘的宽度在1/3D和20之间取小

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.防火卷帘应具有火灾时靠自重自动关闭功能；不应采用水平、侧向防火卷帘。

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.除规范另有规定外，防火卷帘的耐火极限不应低于规范对所设置部位墙体的耐火极限要求。

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.当防火卷帘的耐火极限符合现行标准《门和卷帘的耐火试验方法》GB/T7633有关耐火完整性和耐火隔热性的判定条件时，可不设置自动喷水灭火系统保护。当防火卷帘的耐火极限仅符合现行标准《门和卷帘的耐火试验方法》GB/T7633有关耐火完整性的判定条件时，应设置自动喷水灭火系统保护。自动喷水灭火系统的设计应符合现行标准《自动喷水灭火系统设计规范》GB50084的规定，但火灾延续时间不应小于该防火卷帘的耐火极限。

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.

将3与4条，放到一起解释：

Put 3 and 4 together to explain:

举例，多层煤粉厂房，二级耐火等级，每层采用防火墙划分若干个防火分区，防火分隔部位宽度为27m，由于工艺要求，防火墙上设置防火卷帘。

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.

则该非隔热性防火卷帘应如何设置？

How should the non thermal insulation fireproof roller shutter be set?

第3条说的是防火卷帘的耐火极限要与它所在的墙体的耐火极限一样。

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条说的是防火卷帘是否需要设置自喷系统保护的问题。

Article 4 discusses the issue of whether a self spraying system needs to be installed for protection of fireproof rolling shutters.

如果防火卷帘既有耐火完整性又有耐火隔热性，可不设自喷保护；若只有耐火完整性，应设自喷保护。

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.
