Abstract

A drain device for draining flat roofs, balconies, terraces or other flat structures, has an inflow body provided with a collar rim. When the inflow body is mounted, the collar rim lies on the surface of the roof. A loose flange can be introduced into the inflow body. The flange also has a collar rim. A connector film can be tensed between the collar rims of the inflow body and the loose flange for establishing a tight connection of a covering layer between said two elements. In order to allow for abnormally large amounts of water to be drained, the inflow body is provided with a cavity, into which two drain pipes and lead. One of the drain pipes co-operates with a pressurized, i.e., a pumped drainage system, and the other one of the drain pipes cooperates with a free-flowing drainage system.

Claims7

Dependent claims

A device for draining a flat structure, comprising:

an inlet body formed with an inlet and with a collar rim to be placed on a surface of the flat structure when the device is installed, and with a chamber having a substantially flat base;
a loose flange member having a collar rim and being formed to be fitted into said inlet, wherein said collar rim of said inlet body and said collar rim of said loose flange member form a space to accommodate a connecting sheet and bracing the connecting sheet therebetween to produce a leaktight connection for a covering layer;
a first drainpipe and a second drainpipe each communicating with said chamber of said inlet body and connected to pressure drainage and free-flow drainage systems;
said first drainpipe having an inlet socket lying directly in said base of said chamber and said second drainpipe having an inlet socket above said chamber.
