The production requirements of fire-proof rolling shutter door are very high, and we should pay more attention to the details. For example, the problem of blocking is to prevent the spread of open fire and fire smoke, which is an indispensable part of fire-proof rolling shutter door.

防火卷簾門的封堵根據不同位子，采用的材質也不一樣。一樘卷簾門有三面封堵：上封堵、左封堵、右封堵，我們先說說上封堵，上封堵一般采用卷簾門門體同款材質，制作一個包罩，然后罩住防火卷簾門的電機、卷軸及傳動裝置等，形成一個隔火隔煙的密閉空間，保護傳動裝置，避免火災影響防火卷簾門的運行。

The material used for blocking the fireproof rolling shutter door is also different according to different seats. A rolling shutter door is blocked on three sides: upper blocking, left blocking and right blocking. Let's talk about upper blocking first. The upper blocking is generally made of the same material as the rolling shutter door body, making a cover, and then covering the motor, reel and transmission device of the fireproof rolling shutter door to form a fire-proof and smoke-proof confined space to protect the transmission device, Prevent fire from affecting the operation of fireproof rolling shutter door.

一般的防火卷簾門的左、右封堵采用的是軌道+混凝土模式，如果安裝的是掩埋型軌道，我們只需要把軌道與墻體之間的縫隙填充好就可以。如果采用的是外露型軌道，我們需要做的就是固定好軌道之后，把軌道與角鐵還有墻體的縫隙用混凝土填充即可。

The left and right blocking of the general fire rolling shutter door adopts the track + concrete mode. If the buried track is installed, we only need to fill the gap between the track and the wall. If the exposed track is used, what we need to do is to fix the track and fill the gap between the track and the angle iron and the wall with concrete.

完成這些的話就算是完成防火卷簾門的封堵工程，于煙霧會不會透過軌道與門體的縫隙，這點大家不用擔心，理想門業的防火卷簾門軌道都會在軌道內安裝防煙膠條，很好的阻礙煙霧蔓延。

If these works are completed, even if the sealing project of the fire shutter door is completed, we don't have to worry about whether the smoke will pass through the gap between the track and the door body. The ideal fire shutter door track of the door industry will install smoke proof adhesive strips in the track to well hinder the spread of smoke.
