Description

Technical Field

[0001] The utility model relates to the technical field of air ducts, in particular to a household pre-buried galvanized air duct. Background Art

[0002] The air duct is a piping system used for air delivery and distribution. There are two types: composite air duct and inorganic air duct. Composite air duct is represented by air duct. It can be classified according to the cross-sectional shape and material. The production of stainless steel air duct is to apply sealant to the gaps such as the bite seam, rivet seam, and flange corners. The surface dust and oil should be removed before applying the sealant. According to the cross-sectional shape, the air duct can be divided into circular air duct, rectangular air duct, oblate air duct and other types. Among them, the circular air duct has the smallest resistance but the largest height dimension and is complex to produce. Therefore, the application is mainly rectangular air duct. According to the material, the air duct can be divided into metal air duct, composite air duct, polymer air duct. Among them, the metal air duct is the air duct made of various metal materials. Commonly used ones include galvanized iron sheets and stainless steel. With the continuous development of the storage tank industry, more and more industries and companies have used storage tanks, and more and more companies have entered the storage tank industry. Composite air ducts are composed of various inorganic or organic materials. They are divided into many types according to their composition, but most of them are lightweight, porous, and have high thermal resistance. The extruded insulation air duct series products are suitable for the installation of air conditioning and ventilation projects in industry and various buildings. They are widely used in food processing, machinery manufacturing, pharmaceutical products, electronics industry, shopping centers, cotton textiles, sports and entertainment cultural venues, hotels, guesthouses, supermarkets, office buildings, government agencies, small villas, family residences, aerospace manufacturing and other fields.

Then other main pipes are assembled from the top and bottom directions to ensure that the reinforcing steel bars are staggered and inserted into the inside of the docking groove. Finally, mold concrete is injected from the casting hole outside the wall body, so that the integrated pipe and the wall panel are combined to realize the pre-buried ventilation duct, which effectively solves the problem that the existing ventilation ducts are mostly built by masonry or composite board casting, and the construction process is troublesome and the construction process is inconvenient.
