Definitions
- the invention relates to a water drain for sealed flat surfaces with a vertical drain pipe, with a drain opening in the flat surface opens and is dimensioned so that at a low accumulation height of the water on the flat surface a free-flowing drain through the drain pipe takes place and at a greater accumulation height by the filling of the drain pipe, a negative pressure can be formed by the outflowing water.
- plane surfaces in this sense are such sealed surfaces on which due to their low or not present tilt water regularly or not fast drains enough so that accumulation water levels develop on the surface.
- the drain is inserted in a trough introduced into the flat surface and consists of a sieve forming side wall and a flat closed Cover.
- the lid is located below the edge of the trough, ie below the flat surface. The function of the closed lid is therein, with a vortex formation of the water outlet, the entry of air into to prevent the drainpipe, so that the drainpipe is completely filled with water can fill.
- the invention is therefore based on the problem, a water flow of the initially mentioned type so that higher flow rates at given maximum accumulation heights can be achieved.
- the water drainage according to the invention is based on a different functional principle as the previously known water courses. While the known water courses To the goal, a free flow of water through the drain pipe in as possible To ensure a more uniform shape, the invention is based Water drain on the use of a suction effect. Accordingly, the Forming a negative pressure by running in the filled drain pipe Water column is not prevented, but sought according to the invention, by the suction effect to achieve an increased flow through the drain pipe.
- the container used in the invention is designed so that above the inlet openings forms an air space, which upon reaching a Accumulation height on the flat surface, which corresponds to the height of the inlet openings, Airtight is completed, so that a vacuum chamber above the water surface formed in the container, which serves as a calming space for over the Inlet openings sucked water flow acts.
- a vacuum chamber above the water surface formed in the container which serves as a calming space for over the Inlet openings sucked water flow acts.
- the damming height the water below the level of the inlet openings, finds a normal Free-flowing drain through the drain pipe instead. Is it due, for example a heavy rainfall to an increase in the damming height of the water beyond the height of the inlet openings, the air space in the container sealed watertight above the inlet openings.
- the drain pipe In a complete Filling the drain pipe then creates a negative pressure in the air space, the increased suction of water into the container interior through the inlet openings through. Due to the increasing negative pressure is the Container filled more and more, with an increased flow rate through the drain pipe is achieved because the water level in the tank well above the water level Outside the container is, the drainage performance of a significant greater accumulation height than it actually is on the flat surface has trained.
- Wasserablaufs is the container with a container bottom and provided with a projecting into the drain opening pipe section.
- One Such container can be easily in the plane Insert surface existing drainpipe, especially if he attached to a fixed on the flat surface mounting plate becomes.
- the attachment of the container on the mounting plate is preferably carried out detachable, for which the container bottom preferably for Passage of arranged on the mounting plate locking elements having provided attachment openings.
- the mounting holes and locking elements can be special expediently be designed so that the container on the Locking elements placed and by a turn around his Central axis in a locked position in the manner of a bayonet closure can be brought. In this way succeeds both a simple installation as well as a simple disassembly of the container - and thus the entire water flow.
- the inventive Water drain necessarily arising noise can be in a particular embodiment of the invention thereby reduce that in the container at least one the drain opening comprehensive inner container is arranged in his Side wall corresponding to the inlet openings of the container Inlet has openings whose height is smaller than the height of Sidewall is and above the inlet openings airtight is trained.
- the inner container works in principle the same way as the container, so contributes to training a negative pressure by the running water at.
- the inner container forms its own vacuum system, the pressure drop between the negative pressure in the drain pipe and the atmospheric pressure bridged at least in two stages.
- the outside the inner container formed chamber of the container serves as Vortex chamber and forms a first pressure level, during the Inner container forms a second pressure level.
- Figure 1 shows a concrete ceiling 1 of a flat roof, with a waterproof roof covering 2 is covered, which is generally off consists of welded together bitumen membranes.
- the concrete ceiling 1 has a circular penetration at suitable locations, in which a drain pipe 3 is inserted.
- the drain pipe opens into a drain opening 4.
- the Concrete ceiling 1 In the region of the drain pipe 3 is the Concrete ceiling 1 at the top with an example circular Recess 5 provided, in which a base plate 6 is inserted and connected to the concrete ceiling 1 by known means is.
- the roof skin 2 is on the Surface of the base plate 6 is guided and is at its top with a ring-shaped mounting plate 7 sealingly clamped, with screws 8 through the roof skin through with the base plate 6 is connected.
- the top of the mounting plate 7 Aligns with the top of the roof skin 2.
- the drain pipe prepared in this way becomes an inventive Water drain by placing a cylindrical container.
- inlet openings 14th formed, which extend to the container bottom 12.
- figure 1 shows that the height of the inlet openings significantly lower as the height of the side wall 11 is. In the illustrated here preferred embodiment is the height of the inlet openings 14 less than one third of the height of the side wall 11th
- the container bottom 12 has attachment openings 15, through the locking elements 16 of the mounting plate 7 with a spacer 17 protrude and with an elongated head piece 18, which has a sloping underside 19 in the form of a lower edge has, on the container bottom 12 for its attachment on the mounting plate 7 presses.
- the mounting plate 7 made of a material with a pressed against the Container bottom 12 formed sealing effect.
- the mounting plate 7, for example, from a viscoplastic deformable Elastomer consist.
- the drain pipe 3 ends in the region of the recess 5 of the concrete ceiling 1.
- the formed pipeline is in the area of the heat insulating layer 21 through an inserted transition pipe section 22nd continued, then inserted into the pipe section 13 of the container 9 is.
- Figure 2 serves only to illustrate that the inventive Water drain, of course, even with a flat roof with insulation in a substantially unchanged manner feasible is.
- the attachment openings 15 each consist of a radial extended longitudinal slot 23 and a substantially vertical to standing arc section 24, the one on the center the container bottom 12 centered radius is.
- the longitudinal slot 23 allows the passage of the head piece 18 of the locking element 16 of the mounting plate 7 in the interior of the container 9.
- the spacer 17 in the arc section 24 By turning the container 9 in a clockwise direction the spacer 17 in the arc section 24 to the end guided, whereby the container 9 is locked to the mounting plate 7 is attached.
- At the attachment take in the illustrated Embodiment four locking elements 16 and four mounting holes 15 part. Through the sloping bottom 19 of the locking elements 16, the container bottom 12th firmly pressed against the mounting plate 7, so that there is a sealing Effect is readily achievable.
- FIG. 4 In the further embodiment shown in Figure 4 is the top wall 10 'of the container 9 with the side wall 11 by evenly distributed on a radius screws 25th releasably secured by a ring seal 26.
- an inner container 27 surrounding the discharge opening 4 is arranged, the of a cylindrical side wall 28 and a Cover wall 29 consists.
- the side wall 28 has the inlet openings 14 of the container 9 corresponding inlet openings 30 on, also as downwardly open slots in the side wall 28 are formed. Above the inlet openings 30 the inner container 27 is airtight.
- Figure 4 shows that the container bottom 12 with at a Mounting flange 31 fastened bolt 32 is attached. At the same time the inner container 27 is mounted in this way, the at a radially outwardly directed annular flange 33rd Through openings 34 for the bolt 32 has.
- the additional inner container 27 provides a stepped transition from the atmospheric pressure to the negative pressure in the drain pipe 3 and for a significant reduction in noise through the sucked through the drain pipe 3 water.
- the illustrated embodiments can be through the Modify specialist in many ways. That's the way it is, for example not mandatory that the top wall 10 by a flat plate is formed. It could also be arcuate or tapered be formed. Furthermore, the inlet openings 14 are also modified in shape, for example by a deviation from a straight top edge. Further can the inlet openings 14 also by a grid or a Variety of juxtaposed slots be formed to the penetration of clogging solids in the drain pipe. 3 to prevent. In general, however, it will be useful be, for this purpose a separate grid with distance from the housing. 9 provided.
- the inlet opening 4 the drain pipe 3 practically opposite the drain pipe 3 is not extended, because an extension rather the vacuum education interferes with the closed water column in the drain pipe 3. It is but not excluded by the invention, at the top of the drainage pipe 3 a with respect to the drain pipe 3 extended Drain opening 4 provide.
