Embodiment Construction
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0018] refer to Figure 1-6 , a fireproof ventilation duct for a super high-rise building, comprising a first metal plate 3 positioned around the ventilation duct, a second metal plate 15 is installed outside the ventilation duct, and a polymer is installed between the second metal plate 15 and the first metal plate 3 Styrene foam board 10, by adding polystyrene foam board 10, it can play a heat insulation effect, thereby reducing the high-temperature heat transfer from the surrounding environment to the inside of the ventilation duct, thereby reducing the direct impact of high temperature on the ventilation duct, This also increases the service life of the ventilati...

The invention provides a fireproof ventilating pipeline for a super high-rise building and relates to the technical field of ventilating pipelines. The fireproof ventilating pipeline comprises a first metal plate located on the periphery of the ventilating pipeline, a second metal plate is mounted outside the ventilating pipeline, and a polystyrene foam plate is mounted between the second metal plate and the first metal plate. The first metal plate is further fixedly connected with the ventilating pipeline through two connecting pieces, a high-manganese steel plate is further coaxially mounted outside the first metal plate, and a graphite layer is arranged between the high-manganese steel plate and the first metal plate in a filled mode. A first metal block is arranged at one end of the high-manganese steel plate, and a third mounting groove capable of being matched with the high-manganese steel plate for mounting is formed in the side face, making contact with the high-manganese steel plate, of the first metal block. The fireproof ventilating pipeline for the super high-rise building is simple in structure, the fireproof and heat resistance effects can be achieved on the ventilating pipeline, assembly can be convenient, and thus the time needed for mounting is saved.
Description
technical field [0001] The invention relates to the technical field of ventilation ducts, in particular to a fireproof ventilation duct for super high-rise buildings. Background technique [0002] Ventilation ducts are used to replace and circulate air in the indoor environment. However, in the prior art, the ventilation ducts are made of metal, but in the surrounding high temperature environment for a long time, the ventilation ducts are also easily affected by the temperature, thus affecting the ventilation ducts. If there is damage in some places, and there are gaps in the connection between the ventilation pipes, the high temperature of the fire will easily cause distortion and damage to the sides of the ventilation pipes, which will affect the normal operation of the ventilation pipes, making it more expensive to replace the ventilation pipes. Human and financial costs. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomin...
