Fireproof coating structure for building pipeline

Abstract

Provided is a fireproof coating structure for a building pipeline. The main body of the coating structure comprises a plurality of coating units. Each of the coating units comprises a rectangular fireproof composite sheet tightly covering the periphery of the pipeline around the axis of the pipeline. The rectangular fireproof composite sheet is composed of a fiber core blanket and an aluminum foilfiber composite veneer material. The rectangular fireproof composite sheet comprises a first end edge and a second end edge wrapping up around the pipeline. The second end edge is placed on the firstend edge, and extends to form a first lamination. The end, in the pipeline axial direction, of each of the coating units and the corresponding end of another adjacent coating unit overlap each otherand overlapped inside and outside, and a second lamination is formed. The periphery of the second lamination is bound with wire ties along the periphery of the pipeline, and / or, the periphery of the second lamination is provided with a plurality of fastening nails. By adopting the fireproof coating structure for the building pipeline, the problems of poor sealing, large additional weight and low adaptability of an existing building pipeline fire-resistant structure can be effectively solved, and the fireproof coating structure for the building pipeline has good fixing performance.

Description

technical field [0001] The invention relates to a building passive fire protection system, in particular to a fire protection covering structure of a building pipeline. Background technique [0002] The fire performance of building materials is an important safety standard for modern buildings. If the fire performance of building materials is not up to standard, once a fire breaks out, it will cause heavy losses. In particular, the number of modern high-rise buildings is increasing, which has the advantages of complex functions, large scale, and concentrated personnel, and therefore will generate greater fire safety hazards. [0003] Building pipes need to have a certain fireproof function, especially the fireproof performance of ventilation pipes is particularly important. In the event of a fire, various indoor furniture and decoration materials will produce a large amount of toxic gases. Ventilation ducts are piping systems used for air transportation and distribution. ...

AI Technical Summary

Problems solved by technology

First of all, the hard structure is usually directly spliced ​​by multiple hard fireproof boards, and there are gaps at the spliced ​​parts of the boards, resulting in poor airtightness

Secondly, the hard structure is the high density of the fireproof board, which makes the system heavy, difficult to carry, and high risk factor for installation at high places

Furthermore, the hard structure must be used together with metal keels and screws to complete the fireproof coating of the pipeline; the structure is complex, the construction is difficult, the construction period is long, and the cost is high

In addition, the fireproof board and metal keel are hard materials, which cause loud noise and serious dust pollution during cutting; it is also impossible to carry out standardized construction for complex and changeable piping systems, with poor adaptability and poor shock resistance
