Description

Technical Field

[0001] The invention relates to a building passive fire protection system, and in particular to a building pipeline fire protection covering structure. Background Art

[0002] The fire resistance of building materials is an important safety standard for modern buildings. If the fire resistance of building materials is not up to standard, once a fire occurs, it will cause significant 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 cause greater fire safety hazards.

[0003] Building pipes need to have certain fire prevention functions, especially the fire prevention performance of ventilation ducts is particularly important. In the event of a fire, various types of furniture and decoration materials in the room will produce a large amount of toxic gases. Ventilation ducts are pipe systems used for air transportation and distribution. In large public places, they not only have to bear the role of ventilation, but also have to bear the removal of toxic gases. Therefore, the fire prevention performance of the pipeline itself is also critical. If the toxic gas is not removed effectively, it will directly cause casualties, and it is also easy to increase the fire and cause greater economic losses.

[0004] However, the existing technology still has certain drawbacks. Existing building pipeline fire protection generally adopts a hard fireproof board outer covering structure. It usually covers the outside of the pipeline with rock wool as a thermal insulation layer, and then fixes the fireproof board as a fire-resistant layer on the periphery of the rock wool. First, the hard structure is usually directly spliced ​​by multiple hard fireproof boards, and there are gaps at the splicing of the boards, and the sealing is poor. Secondly, the hard structure is that the density of the fireproof board is high, which makes the system heavy, difficult to carry, and has a high risk factor for high-altitude installation. Furthermore, the hard structure must be used in conjunction with metal keels and screws to complete the pipeline fireproof covering; its structure is complex, the construction is difficult, the construction period is long, and the cost is high. In addition, the fireproof board and the metal keel are hard materials, which make loud noises and serious dust pollution when cutting; it is also impossible to carry out standardized construction of complex and changeable pipeline systems, and the adaptability is poor and the seismic resistance is poor.

[0005] In view of this, how to design a fireproof coating structure for building pipelines that can effectively solve the above-mentioned problems of fireproof rigid structures of building pipelines is the research topic of the present invention. Summary of the invention

[0006] The invention provides a fireproof covering structure for building pipelines, the purpose of which is to achieve good sealing performance, light weight and high adaptability for building pipelines.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a fireproof coating structure for building pipelines, the innovation of which is that the main body of the coating structure is composed of a plurality of coating units, which are arranged linearly in sequence along the axial direction of the pipeline. The coating unit is a rectangular fireproof composite material sheet that tightly coats the outer periphery of the pipeline around the axial direction of the pipeline, and the rectangular fireproof composite material sheet includes a first end edge and a second end edge in the circumferential direction of the pipeline, and the second end edge is overlapped on the first end edge and then extends to form a first laminated portion. The end of each coating unit in the axial direction of the pipeline and the corresponding end of another adjacent coating unit are overlapped with each other to form an inner and outer laminated arrangement to form a second laminated portion. In addition, the outer periphery of the second laminated portion is wrapped with a cable tie along the circumferential direction of the pipeline, and / or the outer periphery of the second laminated portion is provided with a plurality of fixing nails, which fasten the layers of the second laminated portion, thereby positioning the coating structure on the outer periphery of the pipeline. The rectangular fireproof composite material sheet is composed of a fiber core blanket and an aluminum foil fiber composite veneer material, and the aluminum foil fiber composite veneer material is completely encapsulated outside the fiber core blanket.

[0008] The relevant contents in the above technical solution are explained as follows:

[0009] 1. The "fiber core blanket" is an inorganic fiber blanket whose main component includes silicate and has a heat insulation function. The "aluminum foil fiber composite veneer material" encapsulated on the surface of the fiber core blanket is a composite material of aluminum foil and glass fiber. The aluminum foil layer is located on the outside of the glass fiber layer. The "aluminum foil fiber composite veneer material" can increase the tensile and tearing strength of the coiled material, block moisture, and prevent fiber leakage.

[0010] 2. In this solution, preferably, the thickness of the fireproof composite material sheet is less than or equal to 50 mm, and the density ranges from 64 kg / m3 to 128 kg / m3.

[0011] 3. In this solution, preferably, the width of the first laminated portion is 75-90 mm.

[0012] 4. In this solution, preferably, the width of the second laminated portion is 75-90 mm.

[0013] 5. In this solution, preferably, a filament fiber tape is also attached to the first laminated portion, and the filament fiber tape is connected across the first end edge and the second end edge of the covering unit to temporarily fix it.

[0014] 6. In this solution, preferably, the wrapping unit between adjacent second laminated parts is provided with the said tie band for bundling along the circumference of the pipe, and / or, the wrapping unit between adjacent second laminated parts is provided with a plurality of said fixing nails.

[0015] 7. In this solution, preferably, the spacing between the fixing nails in the circumferential direction of the pipeline is less than or equal to 305 mm to ensure the fixing strength.

[0016] 8. In this solution, preferably, the spacing between the fixing nails in the axial direction of the pipeline is less than or equal to 270 mm to ensure the fixing strength.

[0017] Compared with the existing rigid fireproof structures dedicated to building pipes, the present invention provides a fireproof coating structure for building pipes, which can effectively solve the problems of poor sealing, large additional weight and low adaptability. The beneficial effects of the present invention are:

[0018] 1. The fireproof flexible coiled material covering structure adopts the lamination butt joint method of the first lamination part and the second lamination part, and has good sealing performance.

[0019] 2. Compared with the prior art, the fireproof flexible coiled material covering structure can be fixed by combining the reinforcement of filament fiber tape, cable tie and fixing nails. On the one hand, the required installation tools and accessories are few in specifications, and the standardization and versatility are strong; on the other hand, the structure is simple and the construction difficulty is low.

[0020] 3. A tie band is provided around the outer periphery of the second laminated part and / or between adjacent second laminated parts along the circumference of the pipe for bundling; a plurality of fixing nails are provided around the outer periphery of the second laminated part and / or between adjacent second laminated parts, and the fixing nails fasten the layers of the second laminated part. The above arrangement can effectively fix the coating structure on the pipe.

[0021] 4. Compared with the existing technology, this fireproof flexible coiled material covering structure has low requirements for on-site space and high adaptability, and can be well adapted to installation in narrow spaces and areas with complex and staggered pipelines.

[0022] 5. The fireproof flexible coiled material covering structure has low density and light weight, which is one tenth of the existing fireproof board. It is easy to transport and carry, and has a low risk factor when installed at high places.

[0023] 6. The fireproof flexible coiled material covering structure adopts flexible coiled material, which has high temperature resistance and heat insulation fireproof function. Among them, the fiber core blanket has heat insulation function, and the aluminum foil fiber composite veneer material encapsulated on the surface of the fiber core blanket can increase the tensile and tearing strength of the coiled material, block moisture, and prevent fiber leakage.
