Embodiment Construction

[0042]Taking a prefabricated steel structure residential project as an example, the structural system adopts a steel structure, the floor is a laminated floor, and the outer wall is made of ALC autoclaved aerated concrete slabs, with thermal insulation and decorative integrated panels. The building has 18 floors above ground, with a floor height of 2.9 meters. Each building has a total construction area of ​​13,000 square meters and is delivered with fine decoration. The fresh air system is installed indoors, and the I-beam beams in the building are of different sizes such as 400×300mm, 500×300mm, 600×400mm and so on. After the I-beam flange cavity on one side is closed, the net cross-sectional area is about 0.06 to 0.12 square meters. The air flow speed of the fresh air system is designed to be 5m / s, and the number of fresh air changes is 8 times / h. It can be calculated that the fresh air exchange volume of each household is about 1500m 3 / h, which can meet the ventilation...

Abstract

The invention discloses an assembled steel structure combined air duct system and a construction method thereof, which include columns in the steel structure, I-beams connected between the columns, an air duct system containing the I-beams, and indoor ventilation areas The air duct system includes the fresh air unit, the fresh air duct and the exhaust duct connected to the fresh air unit, the fresh air ventilation duct connected between the fresh air unit and the fresh air duct, the exhaust ventilation duct connected between the fresh air unit and the exhaust duct, and the connection The fresh air outlet on the fresh air duct and the exhaust air outlet connected to the exhaust duct; both the fresh air duct and the exhaust duct are surrounded by a sealing plate connected to the opening on one side of the I-beam. The present invention forms the setting of the air duct after the I-beam is sealed, which is beneficial to use the structural characteristics, saves construction and cost investment; and the I-beam doubles as the air duct to ensure the full distribution and orderly connection of the air duct in the overall structure; Through the division of indoor areas, it is beneficial to meet the ventilation needs of different functional areas to the greatest extent.

Description

technical field [0001] The invention belongs to the field of building construction, in particular to an assembled steel structure combined air duct system and a construction method thereof. Background technique [0002] Indoor air quality is an important indicator of applicability in the use of buildings, and it is also the desire of modern people to pursue a higher quality of life. In order to protect people's lives and health, all types of civil buildings need to be equipped with exhaust, supply, and fresh air. And other ventilation systems to ensure indoor air quality. The fresh air system is one of the important categories. The fresh air system of the building needs to be equipped with independent air supply and exhaust ducts, and the fresh air and exhaust ducts are respectively laid to each main functional room. Existing fresh air system pipes need to be installed separately, the cost is high, and the length of the air pipe is long. When passing through side walls, dum...
