The fire rolling shutter has the same function as the firewall to play a horizontal fire separation. It is composed of 13 parts, such as shutter, base plate, guide rail, support, reel, box, control box, door rolling machine, limiter, door header, manual quick release switch, button switch and safety equipment. Generally, the equipment is at the location where it is not convenient to use firewall for separation. For example, open the elevator hall, escalator, the spacious business hall of the department store, the exhibition hall of the exhibition building, and the parts of the building with large openings that cannot use fire doors and windows. The fireproof rolling shutter door has been widely used in the construction project for the fireproof partition. In the equipment process of super fireproof rolling shutter, the previous technical preparation is essential. Because the technical requirements are relatively high, special attention should be paid to the equipment preparation of the super fireproof rolling shutter.
In the use of fire rolling shutter doors, super fire rolling shutter doors are loved by a wide range of users because they have better product functions than general fire rolling shutter doors. As a result, more and more people want to equip super fireproof rolling shutter doors. However, not everyone can quickly and effectively end the fire shutter equipment program, but professional methods and technologies are required to ensure the equipment quality.
On site technicians, constructors, budget officers and quality inspectors carefully understand the drawings, understand the planning intent, fully understand and master all the contents of the construction drawings, check whether the dimensions of the embedded parts and embedded holes between different disciplines are consistent or missing, especially the on-site construction personnel need to understand and check the drawings, do a good job in the joint review of the drawings, and equip measurement Measure things, materials and test tools, and do a good job in maintenance and confirmation. Optimize the construction organization planning, prepare the formwork assembly drawing, cast-in-place slab formwork support drawing, and plan the internal support; Prepare construction survey, construction scheme and quality control method of each sub part project, prepare preventive measures for common quality problems, and prepare construction process specifications.
After the technical preparation in all aspects is completed, the equipment for special fire shutter can be carried out smoothly in advance, and solutions can be found quickly when problems occur, so that the equipment work will not be affected and will be completed smoothly.
Classification and application scope of super fireproof rolling shutter door
Classification of fireproof rolling shutter:
By material: steel, composite, inorganic, etc.
According to the equipment method: in the wall and on the side of the wall (or inside and outside the tunnel).
According to the opening direction, it can be divided into two types: roll up and side roll.
There is no * * * specification for the classification of fire performance of fire resisting rolling shutters. General technical requirements for steel fire resisting rolling shutters (GB14102) divide general steel fire resisting rolling shutters into:
Level 1, fire resistance time 1.50h
F2, fire resistance time 2.0h
Composite steel fireproof roller shutter is divided into:
Class F3, fire resistance time 2.50h
F4, fire resistance time 3.00h
