Roof with drainage gradient greater than 10% is called sloping roof or sloping roof. The form and slope of sloping roof mainly depend on building plane, structural form, roofing material, climate environment, customs and architectural modeling and other factors. ?
Slope roof The slopes of a double-slope or multi-slope roof intersect, and the horizontal intersection line at the top is called the positive ridge; The oblique line that the inclined planes intersect to form convex angles is called oblique ridge; The diagonal line that the inclined planes intersect to form a concave angle is called an inclined gutter. A sloping roof without a positive ridge is called a rolling shed roof. Hard hilltops, suspended hilltops and resting hilltops can all be made into roll-shed roofs.
In addition, the sloping mountain, Ding Dian and pyramid roof can also be arranged in the form of double eaves as required.
Extended data:
Whether the selection of roof slope is reasonable or not affects the waterproof effect of roof. The slope is mainly determined by the performance and structure of the selected roofing waterproof layer material. If you choose materials with good waterproof performance, large single block area and few joints, such as coiled materials, self-waterproof components, metal sheets, etc. The slope can be smaller; If the roof is paved with tiles, the tiles are small, there are many joints and the slope is larger.
In cold areas, in order to prevent a lot of snow on the roof, the slope should be steep; Roof with attic often adopts steep slope roof or two kinds of folding roofs with different slopes.
The 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.
