Description

Technical Field

[0001] The invention relates to the technical field of building maintenance system engineering, and in particular to a natural drainage structure in the eaves of a metal roof aluminum plate and a control method thereof. Background Art

[0002] In recent years, with the development of modern architecture, steel structure has been continuously developing in the construction industry due to its own superior performance. Metal roof maintenance system has gradually replaced the traditional flexible or concrete roof maintenance system and has been widely used in conference and exhibition centers, large sports stadiums, railway passenger platforms, airport terminals, municipal and cultural public facilities, museums, theaters, various industrial and civil buildings, etc., making the building from bulky to light, from gray to beautiful.

[0003] Roof drainage usually adopts organized drainage or unorganized drainage. Unorganized drainage is also called natural drainage, which refers to a drainage method in which rainwater falls directly from the roof eaves to the outdoor ground under the action of gravity. This poses a great safety hazard. Organized drainage is difficult to meet the design requirements of some buildings that require no rainwater pipes on the facade of the building.

[0004] With the diversification of architectural shapes, decorative aluminum panels are widely used. However, due to the influence of architectural shapes, there are some roofs with natural drainage at the eaves. For roofs with natural drainage at the eaves, the usual practice is either to have irregular natural drainage on the aluminum plate or to have natural drainage inside the aluminum plate. The former is disorderly and unsightly; the latter generally uses purlins or steel frame extensions, and water washes on the steel frame, which is very easy to rust. Therefore, it is very important for the natural drainage inside the eaves of the metal roof aluminum plate to meet the internal drainage needs without affecting the durability of the structure. Summary of the invention
