Examples of matters needing attention in installation method of fire shutter

In some warehouses or warehouse logistics fields, we will find that it is not an ordinary wooden door or steel door, but a fire shutter door similar to the one described below. As the name implies, their performance is more stable, and in emergencies such as fire, they can prevent the fire from spreading further, thus reducing losses and possible economic costs to some extent. Furthermore, we can know that the surface of the fire shutter is coated with a special coating, which can also play a safety role on the premise of beautiful decorative effect.

First, the installation method of fire shutter

1, ventilation pipes and water pipes shall not be set at the upper part of the hole where the shutter door is installed;

2. The power line (tn-s and fire signal line) is laid by the user to the electric cabinet next to the door rolling machine;

3. After the shutter door is installed, install the ceiling, and the edge of the ceiling should be 50mm away from the curtain plate to avoid friction;

4. When debugging and using, it is forbidden to copy the bottom? Stand up. Electrical facilities shall not be dismantled without authorization;

5. According to the fire laws and regulations, the fire shutter door is a special fire-fighting facility and shall not be used for other purposes. Nothing can be stacked directly under the shutters.

6, after the installation and debugging, start once every quarter, check the electrical and mechanical properties, pay attention to the operation safety during the inspection.

7. In the routine fire safety inspection every quarter, the chain lubricating oil for starting the motor must not be missed, which is also an important link missed by many property rights units or fire control units in the inspection.

Second, the fire shutter installation matters needing attention

The area calculation of fire shutter doors shall be carried out in accordance with the national standard "Budget and Final Accounts of Construction Projects".

The calculation method is: (the opening height of the fire shutter door +600mm)× (the opening width of the shutter door +200mm) Note: (the opening height is from the bottom of the beam to the rough ground, and the guide rail needs to be embedded)? The area of frame and lintel is calculated as: (width of hole) × (bottom surface+elevation) expanded calculation area.

What is the height of the roof after measurement? Keep a gap of 30cm.

Third, the layout position

According to the process decision, fire shutter doors should be set in addition to the firewall. If there is no firewall between two fire partitions, fire shutter doors should also be set. Generally located in the following parts.

(1) Close the evacuation stairs and lead to the walkway; Close the elevator room, the door leading to the front room and the front room leading to the walkway.

(2) Inspection doors of vertical pipeline wells such as cable wells, pipeline wells, smoke exhaust channels and garbage channels.

(3) Divide the fire zones and control the firewalls and doors on the fire partition wall in the building area of the zones. When it is difficult to install a firewall or fire door in a building, it should be replaced by a fire shutter door, and at the same time it must be protected by a water curtain.

Main application places of fire shutter

Mainly used in large supermarkets (hypermarkets), large shopping malls, large professional materials markets, large exhibition halls, factories, warehouses and other public places with fire protection requirements. In case of fire, the fire shutter door will automatically descend (descend) under the control of the central fire control system according to the preset procedure, so as to prevent the flame from spreading to other areas and win valuable time for fire fighting and extinguishing.

The manufacturing requirements of fire shutter doors are high, that is, the whole system is required to withstand the high temperature test of about 1 100 for a certain time, and the fire resistance time of fire shutter doors is the main index of fire shutter doors. In GB 14 102-93, the General Technical Conditions for Steel Fire-proof Rolling Door stipulates four fire-proof grades for fire-resistant time.

The use effect of fire shutter in the later period depends not only on the comparative choice of materials brands in the earlier period, but also on the installation skills and precautions. For example, from the above, we can know that the installation of fire shutter needs comprehensive operation with appropriate accessories. In addition, we should know the size and material characteristics of the product. So today, for example, we will introduce the installation steps and possible accessories and tools. You can prepare for your study in advance in case of emergency.
