Someone tell me about the design of sloped roofs in architecture

A sloped roof is a form of roofing.

The main forms of roofing for house buildings are single-side sloped, double-side sloped and four-side sloped roofs. The difference between them is that the roof is composed of several slopes. For example: single-side slope roof is the roof only a sloping plane, from one side of the external wall sloping to the opposite side of the external wall. Mostly used for workshop roofing; double-sided sloped roof refers to the roof has two folded two-way slope surface. Usually used for single-story residential. Such as rural housing is mostly double-slope roofing; four-slope roofing is in the two-slope roofing on both sides of the mountain wall and then add a slope roofing to form a four-slope roofing. Small houses and other levels are mostly four slope roof.

The top line of the slope should be straight or curved, and there should be 3% to 5% backslope in the direction of the top line of the slope.

Discharge unloading platform edge should be set up to set the safety block, its height is not less than 2/5 of the diameter of the tire, the top and bottom of the block width should be not less than 1/3 of the diameter of the tire and 1.3 times; set up a mobile block facilities, according to the requirements of the mobile block operation.

The earth and rock shall be discharged and discarded in the prescribed order, and when unloading and bulldozing operations are carried out on the same lot, sufficient safety distance shall be maintained between the equipment.

When unloading the soil, the car should be perpendicular to the working line of the row of soil; it is strictly prohibited to back up at high speed and ram the safety gear.

When bulldozing, bulldozers are strictly prohibited to bulldoze along the direction of the parallel slope top line at the edge of the row of soil field.

Discharging the soil safety gear or reverse slope does not comply with the provisions of the top line of the slope within 30 meters of the inner side of a large crack or uneven subsidence, prohibit the car to enter the hazardous area, discharging the soil field operators need to discharging the soil field to make timely treatment.
