The slope of the sloping roof varies from 10 to 60 degrees. If it exceeds 10 degrees, it is the sloping roof, and 30 degrees is the best slope, so that the stress on the top surface is reduced and drainage is easy.
A sloping roof is generally 30%, and the slope of sloping roof is generally 10%-60%. A sloping roof with a slope exceeding 10% is a sloping roof. It is an external protective component that separates the top floor of the building from the outdoor. The roof can protect against rain, snow, sun, cold and heat.
Extended data:
Sloped roof, also known as sloping roof, refers to the roof with drainage slope generally greater than 3%. Sloped roofs are widely used in buildings, mainly including single slope type, double slope type, four slope type and folding type.
Double slope and four slope are widely used. The gable protruding from the top of the double-slope roof is called hanging mountain; A gable with a flat roof is called a hard mountain. The four corners of the traditional four slopes in China are inclined, which is called the Temple of Heaven. The main ridge extends and two mountain flower faces are formed on both sides, which is called inclined mountain. The tile line intersects with the sloping roof in the form of pyramid roof, and the treasure roof is often arranged at this point.
There are many kinds of roofing materials, and the selection should be based on supporting structure, roof slope, architectural appearance, durability, fire resistance, waterproof, self-weight, construction requirements, cost and other factors. Commonly used are:
Flat tile roof
This kind of roof is made of clay or cement mortar and molded into uneven flat tiles. The overall size of ceramic tile is generally 400× 230× 15mm, and there are hooks on the back of ceramic tile, which can be hung on the hanging tile. When laying, it must overlap up, down, left and right. This kind of roof is easy to build and widely used in civil buildings. Its disadvantages are small tile size, many joints and easy water leakage.
Wavy tile roof
This kind of roof is commonly used with asbestos cement corrugated tile, steel wire mesh cement corrugated tile, colored glass fiber reinforced plastic corrugated tile, galvanized corrugated iron tile, aluminum alloy corrugated tile and wood fiber corrugated tile after surface coloring and anti-corrosion treatment. Corrugated tiles are light in weight, good in appearance and waterproof, and all kinds of corrugated tiles are covered in similar ways.
For example, asbestos-cement corrugated tiles are usually directly nailed or hooked on purlins with galvanized iron screws or iron hooks, and the spacing between purlins is generally 900 ~ 1200mm. Tiles should be covered from top to bottom and from left to right, and the direction of covering from left to right should follow the dominant wind direction. In order to prevent the joints of the upper, lower, left and right tiles from being uneven, the corner-cutting paving method is generally adopted.
Other roofs
In addition, there are glazed tiles, small blue tiles, cylindrical slab tiles and precast reinforced concrete tile roofs. Glazed tiles are mostly used as roofs or cornices for large public buildings such as memorial halls; Small blue tiles and cylindrical tiles are mostly used in residential buildings; Reinforced concrete roofs include п-shaped plates, F-shaped plates and steel wire cement trough tiles. They are large in size and can be laid directly on the roof truss or purlin, and there is no need to make another roof.
