Abstract
Description
[0001] The drainage of penthouse roof terraces in apartment buildings is typically achieved using a drainage system. The construction of these roof terraces usually includes a layer of drainage material, primarily gravel or crushed stone, above the insulation and waterproofing. The actual water-bearing layer, in the form of paving slabs or similar materials, then rests on this drainage layer.
[0002] In combination with floor-to-ceiling doors, the drainage layer may only be able to be of limited height.
[0003] The roof drainage of the apartment building with penthouses is typically handled by a standard gutter system. However, this system cannot usually be directly connected to the sewer system because of the offset between the roof and the building's exterior walls, due to the aforementioned roof terrace area. Consequently, the roof drainage also occurs via the roof terrace area, resulting in an additional water load. During heavy rainfall, this additional water load can exceed the capacity of the roof terrace drainage system to handle and dissipate it. As a result, water accumulates and flows back into the floor-to-ceiling doorways of the penthouses.
[0004] Due to the limited structure described between the roof terrace waterproofing and the bottom edge of the floor-to-ceiling doors, a sensible and targeted drainage of the roof's water load cannot be achieved using conventional gutters and downpipes.
[0005] The invention specified in claim 1 is based on the problem of creating a conduit system for transporting rainwater, the modular design of which allows the drainage of the roof surface via the area of the roof terrace without placing an additional burden on the drainage system of the roof terrace.
[0006] This problem is solved by the features listed in claim 1.
[0007] The invention achieves targeted roof drainage via the roof terrace area – regardless of the height between the roof terrace waterproofing and the bottom edge of the floor-to-ceiling doors. This eliminates the need for additional conventional piping material, which, in its usual dimensions, would create a significant workload where available installation height is limited.
[0008] An advantageous embodiment is described in claim 2. By increasing the cross-sectional area of the pipe, a reduction in the flow velocity is achieved, which positively influences controlled and harmonious drainage.
[0009] An embodiment of the invention is described with reference to the Fig. 1, Fig. 2, Fig. 3 to Fig. 4 explained. It shows: Fig. 1 the modularly constructed piping system Fig. 2 the connecting piece Fig. 3 the intermediate piece Fig. 4 the end piece Reference symbol list 1 connector 2 Intermediate pieces 3 End piece A1 Cross-sectional area Inlet Connection piece A2 Cross-sectional area Drain connection piece
