特级防火卷帘门需要注意什么？

1. We consulted most of our customers about the level of fire doors. In general, the drawing will show the height of the fire door. The fire door is divided into three grades: A, B and C, indicating the fire integrity of the fire door, i.e. fire resistance time. At present, China's standard is that the fire resistance time of class A is not less than 1.5 hours, that of class B is not less than 1.0 hours, and that of class C is not less than 0.5 hours. Class A is usually used in more important places, such as KTV compartment door, power distribution room and computer room. Class B is usually used for corridors and other places, while class C is usually used for pipeline wells.

2 .防火门材料:所用防火门的等级将在一般建筑图纸上标出，但所用材料不会在图纸上标出，所以很多用户会问是否有几扇防火门？它们都是标准的吗？等等。防火门通常分为钢木门和钢防火门，无论是钢木门还是钢防火门，它们分为三个等级: a、b和c。一般来说，安装在建筑物上的防火门并没有规定使用什么材料。然而，我们在实践中的做法是，钢防火门通常在室内和室外使用，因为它们在打开和关闭时相对安静，钢防火门不会相互碰撞，除了防火之外，钢防火门还可以起到更好的防盗和防损坏作用。

2. Fire door materials: the grade of fire doors used will be marked on the general architectural drawings, but the materials used will not be marked on the drawings, so many users will ask whether there are several fire doors? Are they all standard? wait. Fire doors are usually divided into steel wood doors and steel fire doors. Whether steel wood doors or steel fire doors, they are divided into three grades: A, B and C. Generally speaking, fire doors installed on buildings do not specify what materials to use. However, our practice in practice is that steel fire doors are usually used indoors and outdoors, because they are relatively quiet when opening and closing, and steel fire doors will not collide with each other. In addition to fire prevention, steel fire doors can also play a better role in anti-theft and damage prevention.

3 .防火门的样式和这里要打开的样式主要是指门的形状，如单门、双门、母门等。在实践中，我们认为宽度为1米的防火门可以做成单扇门，宽度为1.2米的防火门可以做成双扇门或母门形状。如果门的一面被建筑物挡住，另一面是敞开的，但是因为门太宽而无法打开，它会影响入口和出口以及美观，母亲门会被做成母子形状，一边大一边小，通常比例是3 / 7。防火门的开启方向主要是指单扇门是向左还是向右开启。我们的一般识别方法是人们站在门外，这意味着所有防火门都向外打开，不允许向里面打开。防火门的开启方向必须与疏散通道的方向相反。因此，向外开门的人站在门外，看着门对面的铰链。如果铰链在左边，它在右边被称为右边，两边的尺寸也由母门决定。

3. The style of fire door and the style to be opened here mainly refer to the shape of the door, such as single door, double door, mother door, etc. In practice, we believe that a fire door with a width of 1m can be made into a single door, and a fire door with a width of 1.2m can be made into a double door or a mother door. If one side of the door is blocked by the building and the other side is open, but the door cannot be opened because it is too wide, it will affect the entrance, exit and beauty. The mother door will be made into a mother child shape, with one side large and the other small, usually with a ratio of 3 / 7. The opening direction of the fire door mainly refers to whether the single door is opened to the left or right. Our general identification method is that people are standing outside the door, which means that all fire doors are opened outward and are not allowed to open inward. The opening direction of the fire door must be opposite to that of the evacuation passage. So the person who opened the door stood outside the door and looked at the hinge opposite the door. If the hinge is on the left, it is called the right on the right, and the size of both sides is also determined by the mother door.

4 .订购防火门尺寸和洞口防火门尺寸:一般来说，有两种涂漆和未涂漆的。我们称之为净尺寸。通常，没有必要扣除它们。未刷漆的意味着可以在没有水泥找平的情况下看到门洞内的砖块。这种门开口需要扣除宽度和高度，通常宽度为20毫米，高度为10毫米。如果你需要铺设地砖，你还需要扣除地砖的尺寸，你还需要强调是放下框架还是嵌入它们。

4. Order fire door size and opening fire door size: Generally speaking, there are two kinds of painted and unpainted. We call it net size. Usually, it is not necessary to deduct them. Unpainted means that the bricks in the door opening can be seen without cement leveling. The width and height of this door opening need to be deducted. Usually, the width is 20mm and the height is 10mm. If you need to lay floor tiles, you also need to deduct the size of floor tiles, and you also need to emphasize whether to put down the frame or embed them.

5、防火门门扇是否加防火玻璃，能增加照明效果。

5. Whether the fireproof glass is added to the door leaf of the fireproof door can increase the lighting effect.
