1、 General regulations

防火分隔部位設(shè)置防火卷簾時(shí)，應(yīng)符合下列規(guī)定：

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

1.除中庭外，當(dāng)防火分隔部位的寬度≤30m時(shí)，防火卷簾的寬度應(yīng)≤10m；當(dāng)防火分隔部位的寬度＞30m時(shí)，防火卷簾的寬度應(yīng)≤該部位寬度的1/3，且應(yīng)≤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(guī)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(méi)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(dāng)需要防火分隔的部分其寬度＞30m時(shí)，設(shè)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(yīng)具有火災(zāi)時(shí)靠自重自動(dòng)關(guān)閉功能；不應(yīng)采用水平、側(cè)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(guī)范另有規(guī)定外，防火卷簾的耐火極限不應(yīng)低于規(guī)范對(duì)所設(shè)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(dāng)防火卷簾的耐火極限符合現(xiàn)行標(biāo)準(zhǔn)《門(mén)和卷簾的耐火試驗(yàn)方法》GB/T7633有關(guān)耐火完整性和耐火隔熱性的判定條件時(shí)，可不設(shè)置自動(dòng)噴水滅火系統(tǒng)保護(hù)。當(dāng)防火卷簾的耐火極限僅符合現(xiàn)行標(biāo)準(zhǔn)《門(mén)和卷簾的耐火試驗(yàn)方法》GB/T7633有關(guān)耐火完整性的判定條件時(shí)，應(yīng)設(shè)置自動(dòng)噴水滅火系統(tǒng)保護(hù)。自動(dòng)噴水滅火系統(tǒng)的設(shè)計(jì)應(yīng)符合現(xiàn)行標(biāo)準(zhǔn)《自動(dòng)噴水滅火系統(tǒng)設(shè)計(jì)規(guī)范》GB50084的規(guī)定，但火災(zāi)延續(xù)時(shí)間不應(yīng)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(jí)耐火等級(jí)，每層采用防火墻劃分若干個(gè)防火分區(qū)，防火分隔部位寬度為27m，由于工藝要求，防火墻上設(shè)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(yīng)如何設(shè)置？

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

第3條說(shuō)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(shuō)的是防火卷簾是否需要設(shè)置自噴系統(tǒng)保護(hù)的問(wèn)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(shè)自噴保護(hù)；若只有耐火完整性，應(yīng)設(shè)自噴保護(hù)。

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.
