Description

Technical Field

[0001] The utility model relates to the technical field of fireproof board installation, in particular to a fireproof board installation structure of a smoke exhaust passage. Background Art

[0002] The smoke exhaust system belongs to the fire protection system. With the development of society, my country's construction industry has also been booming, and the number of modern high-rise buildings has increased. These new buildings have the advantages of complex functions, large scale, and concentrated personnel, which can bring the best experience to people. However, such buildings also have huge safety hazards, especially fire safety hazards. Once a fire occurs, all kinds of furniture and decoration materials in the room will produce a large amount of toxic gas, which will not only affect people's evacuation and escape, but also restrict the normal development of fire fighting operations. Based on this factor, under the premise of scientific and reasonable design of smoke exhaust ducts, the fire resistance limit time of smoke exhaust ducts must be guaranteed to improve their smoke exhaust performance.

[0003] For example, in a patented method for installing a fireproof board of a smoke exhaust system (Announcement No.: CN105863092B), the following steps are included: installing the exhaust pipe in place; dividing the exhaust pipe into several pipe sections according to the flange; installing the insulation board frame at the flange; installing the first fireproof board on the insulation board frame, and laying the second fireproof board on the air duct so that the second fireproof board is fixed on the insulation board frame; wrapping the first fireproof board and the second fireproof board after splicing; bundling the exhaust pipe with the fireproof board with a packing tape, and sealing the joint between the first fireproof board and the second fireproof board with a fireproof tape. The present invention can improve construction efficiency, reduce waste of light steel hubs, and improve construction simplicity.

[0004] The above patent improves construction efficiency, reduces waste of light steel hubs, and improves construction simplicity through the use of insulation board frames and fireproof boards. In daily use, due to the fixation between the corner wrapping treatments, the exhaust pipe may be twisted on the exhaust pipe by bolts, causing the exhaust pipe to be pierced by construction workers, thereby affecting the exhaust effect of the device and reducing the sealing of the device. Therefore, it is necessary to invent a fireproof board installation structure for the exhaust channel to solve the above problems. Utility Model Content
