The electro-galvanizing layer is electroplated on the outer side of the steel pipe sleeve, the zinc layer is corroded slowly in acid, alkali and other mist, the first air pipe 20 in the galvanized layer pipe sleeve can be effectively protected, the first air pipe 20 is prevented from being corroded by the external environment, and the service life of the first air pipe 20 is prolonged. Further, since the zinc plating layer has excellent ductility, the zinc plating layer is not damaged even when the galvanized steel pipe sleeve 22 is subjected to various conditions such as cold punching, rolling, bending, and the like. The surface of the zinc layer also forms a thin and dense zinc oxide layer which is difficult to dissolve in water, so that when the wall 10 is infiltrated, a certain waterproof maintenance effect can be achieved for the first air duct 20.

Referring to fig. 1 and 2, in some embodiments of the present invention, the galvanized steel pipe casing 22 is filled with incombustible material 23 on both the inside and outside thereof. The non-combustible material 23 has a high ignition point, so that the self-ignition of the non-combustible material 23 can be effectively avoided when high-temperature media are transported in the air pipe, meanwhile, the filling of the non-combustible material 23 can also play a role in heat preservation, and when warm air or other media needing heat preservation are transported in the air pipe, the non-combustible material 23 can also play a good role in heat preservation and heat insulation on the premise of ensuring that the non-combustible material can not burn.

In some embodiments of the present invention, further, the noncombustible material 23 may be an asbestos cord. Asbestos ropes, also known as aluminum silicate fiber ropes, are commonly used as thermal insulation materials in various thermal devices and heat transfer systems, or are further processed into other asbestos products. Generally, it is made up by using asbestos as core and making them pass through the process of twisting and braiding. Has the characteristics of heat resistance, corrosion resistance, strong mechanical hardness and the like. Therefore, asbestos cords are filled inside and outside the galvanized steel pipe sleeve 22, so that the galvanized steel pipe sleeve 22 can be effectively protected, and the service life of the galvanized steel pipe sleeve 22 can be prolonged. The asbestos rope can be made of common asbestos twisted ropes which are twisted by a plurality of strands of asbestos wires and are soft, and the asbestos twisted ropes can be used as asbestos wires after being disassembled, can be wound on the outer sides of the galvanized steel pipe sleeves 22 with various sizes and the first air pipe 20, and also play a role in tightly plugging and sealing.

It should be noted that the non-combustible material 23 can also be made of glass wool felt, aluminum silicate needle-punched felt, etc., so that the utility model does not specifically limit the material of the non-combustible material 23, and can achieve the effects of effective flame retardation, heat insulation and heat preservation.

Referring to fig. 1, in some embodiments of the present invention, the second air duct 30 is fixedly connected to the floor 11 through a fixing mechanism 40. One end of the fixing mechanism 40 connects the second air duct 30, and the other end of the fixing mechanism 40 is fastened to the floor 11, so as to fix the second air duct 30 and keep it connected to the first air duct 20 through the flexible connecting pipe 21.

Referring to fig. 1, in some embodiments of the present invention, the securing mechanism 40 is a hanger. Instead of hangers, holders may be used to hold the second duct 30. Therefore, the structure of the fixing mechanism 40 is not limited in particular, and the second air duct 30 can be fixed and suspended and stably connected to the first air duct 20.

In some embodiments of the present invention, one end of the fixing mechanism 40 is installed on the floor 11 through the expansion bolts. When the expansion bolt is used, firstly, a hole with a corresponding size is drilled on the floor slab 11 by using an impact electric drill (hammer), then the bolt and the expansion pipe are arranged in the hole, and the bolt, the expansion pipe, the mounting piece and the floor slab 11 can be expanded into a whole by screwing the nut. The expansion screw utilizes the wedge-shaped inclination to promote the expansion to generate friction bond force, so as to achieve the fixing effect, further ensure that the fixing mechanism 40 can stably lift and fix the second air pipe 30 below the floor slab 11, and effectively avoid the occurrence of safety accidents.

Some embodiments of the present invention, the first air pipe 20 is a steel pipe with a pipe wall thickness of 2 mm. The thinner wall thickness can reduce the weight of the first duct 20 while ensuring the safety strength, thereby facilitating the installation of the first duct 20 in the wall 10. It should be noted that, according to different usage scenarios, the wall thickness of the first air duct 20 is not specifically limited, and may be 2 mm, 3 mm, or even 4 mm.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
