Description

A construction method of a drainage system and a drainage device in a metal roof

Technical Field

The invention relates to the technical field of drainage engineering, and in particular to a construction method of a drainage system and a drainage device in a metal roof.

Background technique

With the continuous development and application of steel structure buildings in recent years, thanks to its advantages such as light weight and high rigidity, a large number of large-span and large-area buildings have begun to use metal roofs. However, due to the different shapes of different metal roofs and their complexity, the drainage design of metal roofs is somewhat difficult. Traditional roof drainage methods mainly include unorganized drainage and organized external drainage. The commonly used unorganized drainage method is that rainwater falls to the ground along the eaves under the action of gravity, which causes great inconvenience to pedestrians. In the cold winter, due to the low temperature, icicles are easily formed at the eaves, and there is a risk of falling at any time, which poses a great safety hazard. It can also prevent the risk of large-scale sliding of snow on the roof to a large extent. Organized external drainage is difficult to meet the design requirements of some buildings that require no rainwater pipes on the facade of the building.

In view of this, those skilled in the art need to develop a construction method for a drainage system and a drainage device in a metal roof.
