Technical Field

The invention relates to a passive fire protection system for a building, in particular to a fire protection cladding structure for a building pipeline.

Background

The fire resistance of building materials is an important safety standard for modern buildings. If the building material has unqualified fireproof performance, the fire disaster can cause great loss. Especially, the number of modern high-rise buildings is more and more, and the modern high-rise buildings have the advantages of complex functions, large scale and centralized personnel, so that greater fire safety hidden dangers can be generated.

The building pipeline needs to have certain fireproof function, and especially the fireproof performance of the ventilation pipeline is particularly important. In case of fire, a large amount of toxic gas is generated from various indoor furniture and decoration materials. Ventilation ducts are duct systems for air transport and distribution, which, in large public places, are responsible not only for ventilation but also for the removal of toxic gases. Therefore, the fire-proof performance of the pipeline is also very critical, and if toxic gas cannot be exhausted, casualties can be directly caused, the fire is easy to increase, and greater economic loss is caused.

However, the prior art has certain disadvantages. The existing building pipeline fire prevention generally adopts a hard fire-proof plate outer cladding structure. The heat insulating pipe is usually coated with rock wool as heat insulating layer and fire-proof plate as fire-proof layer is fixed around the rock wool. Firstly, the hard structure is usually formed by directly splicing a plurality of hard fireproof plates, and the splicing position of the plates has a gap, so that the sealing property is poor. Secondly, the density of this PLASTIC LAMINATED is high for this stereoplasm structure for this system is from great, and the transport is difficult, and the high place installation danger coefficient is high. Moreover, the hard structure can be coated with fire-proof pipeline only by matching and using metal keel and screw; the structure is complex, the construction difficulty is large, the construction period is long, and the cost is high. In addition, the fireproof plate and the metal keel are made of hard materials, so that the cutting noise is high and the dust pollution is serious; and the standardized construction of a complex and variable pipeline system cannot be carried out, the adaptability is poor, and the shock resistance is poor.

In view of the above, the present invention is to design a fireproof covering structure for a building duct, which can effectively solve the above problems of a fireproof hard structure for a building duct.
