Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a drainage ditch structure without a ditch cover on a flat roof. Background Art

[0002] The division of pitched roofs and flat roofs is determined by the size of the slope. Flat roofs are not absolutely flat, but also have a slope, but it is very small, otherwise it is impossible to drain the water on the roof. There is no strict definition of regulations yet. The waterproofing industry believes that a slope greater than 10% is a pitched roof. A roof with a slope less than 5% is a flat roof. Roof drains are drains installed on the roof so that water flows into the ground through the drainage head and does not penetrate the roof. The conventional practice of drains in flat roofs is to construct the roof drains after the drainage ditch brick membrane is completed. The roof waterproofing protective layer is the final surface layer of the drain, and finally the drain is trimmed and shaped with cement mortar and the slope is found. However, this flat roof drain method does not take into account the waterproofing of the flat roof wall, and it is difficult to block rainwater from leaking into the wall and roof; resulting in poor drainage and waterproofing effects. Therefore, it is necessary to provide a flat roof drain structure without a ditch cover to solve the above technical problems. Utility Model Content
