Definitions
- the invention relates to a device for draining water from flat roofs, balconies, terraces or other water-bearing surfaces, and a method for producing such a device.
- the invention also relates to a grass catcher for leaves, gravel or the like.
- Such devices are used to discharge the accumulated on a flat roof, a terrace or a balcony water - especially rainwater - in a drain pipe.
- Such devices are also referred to as gullies. They basically include an inlet body, which is usually funnel-shaped.
- a terminal foil or web for example, a roofing membrane made of flexible polyolefins (FPO) or a bituminous sheet
- FPO flexible polyolefins
- a roof surface can be drained in two ways: by means of a free-flow system or by a pressurized flow system.
- Pressure-flow roof drains are used to ensure safe and economical rain drainage of roof surfaces.
- the roof drain When operating such a drainage system, the roof drain is below full capacity. This results in a negative pressure in the drain pipe, with the result that - in contrast to a free-standing system - with relatively small pipe dimensions large amounts of rainwater can be removed.
- the inlet body made of metal (stainless steel) or plastic are designed.
- this standard thermoplastics use.
- Standard thermoplastics are one of the three groups in which thermoplastics are usually subdivided, among other things due to their temperature resistance: standard thermoplastics, engineering thermoplastics and high-performance thermoplastics.
- Standard thermoplastics are very versatile and are produced in large quantities. These include, for example, polyethylene or polyvinyl chloride. An often used material for the inlet body is polyethylene.
- DE 101 25 642 C1 discloses a device for sealing a water inlet in flat roofs, balconies, terraces or other low-rise buildings, which consists of an inlet body with a collar edge which rests in the inserted state of the inlet body on the roof surface, and wherein in the inlet insert insertable is, which also has a collar edge, and wherein between the collar edge of the inlet body and insert a connection foil is inserted, which is to clamp for sealingly establishing connection of a cover layer between them, wherein cast for receiving a sufficient tension in the inlet body, a ring for receiving clamping elements is, wherein the ring is formed with over the entire wall extending molded sleeves as injection molded part, so that there is a sleeve ring in the wall.
- the ring may be formed of a hard plastic, preferably of a polyamide plastic.
- the sleeves can be designed for self-tapping screws.
- the object of the present invention is to develop a device for draining water in such a way that the overall height of the device can be reduced without adversely affecting the strength and rigidity properties of the device.
- the inlet body may be formed on the one hand of a technical thermoplastic.
- engineering thermoplastics includes in particular polyamide (PA), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polycarbonate (PC), polyoxymethylene (POM), polypropylene (PP) and acrylonitrile-butadiene-styrene (ABS).
- PA polyamide
- PET polyethylene terephthalate
- PBT polybutylene terephthalate
- PC polycarbonate
- POM polyoxymethylene
- PP polypropylene
- ABS acrylonitrile-butadiene-styrene
- engineering thermoplastics have better mechanical properties than standard thermoplastics such as polyethylene or polyvinyl chloride.
- the device according to the invention can have a comparatively low structural height due to the better strength characteristics of the engineering thermoplastic. This may be advantageous when installing the inlet body in the roof skin.
- the inlet body may be formed from a thermoplastic composite material.
- a composite material (also referred to as a composite material) is understood to mean a material consisting generally of two major components (a bedding matrix and reinforcing elements such as particles or fibers). The mutual interactions of the two components gives such material improved mechanical properties.
- the use of such a composite material therefore improves the mechanical properties of the inlet body compared to inlet bodies of standard thermoplastics such as unreinforced polyethylene or polyvinyl chloride, so that the device according to the invention can again have a relatively low overall height due to the better strength characteristics.
- standard thermoplastic such as polyethylene use.
- the apparatus may further comprise a pressing member and means for clamping the pressing member against the inlet body, wherein the inlet body and pressing member are configured so that a terminal foil between the pressing member and inlet body can be jammed.
- the pressing element can be configured as a pressing ring or, in particular in the case of a roof drain for emergency drainage, as Aufstauring.
- the pressing member made of a thermoplastic or thermoplastic composite material.
- the pressing member is formed of the same material as the inlet body.
- the means for clamping the pressing element against the inlet body may comprise at least one bolt or a screw.
- the bolt or screw can then be positively secured in the inlet body and extend through a passage opening in the pressing element, wherein the pressing element is clamped from the side facing away from the inlet body of the pressing member by means of a complementary element against the inlet body.
- the complementary element may be a threaded nut.
- the means for bracing the pressing element against the inlet body may comprise at least one self-tapping threaded screw which is screwed directly into the inlet body, so that it protrudes in the direction of the pressing ring.
- the strength properties of the material used for the inlet body i. of the engineering thermoplastic or thermoplastic composite material, ensure that the self-tapping threaded screws have a secure fit in the inlet body.
- the press ring is thereby clamped against the inlet body that metallic countersunk screws are screwed directly into the inlet body. Over-tightening the screws by applying too high a tightening torque will lead to the destruction of the thread because the PE used does not have the required strength.
- the required bias for pressing the connection film can then not be maintained, and the tightness of the system is at risk.
- the device may also have a catcher for leaves, gravel and the like, which is placed on the inlet body.
- the means for clamping the pressing element against the inlet body can also serve to fix the collecting basket with respect to the inlet body.
- the catcher can be fixed by means of a bolt or a screw with respect to the inlet body, which also serves to clamp the pressing element against the inlet body at the same time. This reduces the number of required components for fixing the leaf trap basket.
- the inlet body it is possible in an area of the inlet body-namely, that which points to the pressing element in the assembled state-to form an annular depression which is designed as a bearing surface for a seal.
- the recess can do so be dimensioned so that at least the seal is embedded in the installed state in the inlet body.
- a height difference between the surface of the inlet body and the bearing surface formed by the annular recess is greater than the material thickness of the seal, in the assembled state and the pressing element can be at least partially embedded in the inlet body, so that the pressing element is not a major flow obstacle.
- the pressing element is at least up to half its height, better still up to two-thirds of its height embedded in the inlet body.
- the material used for the inlet body and possibly the pressing element can be present as a composite or composite material.
- a composite or composite material based on a technical thermoplastic.
- the material can be fiber-reinforced, in particular glass fiber, basalt fiber, carbon fiber or aramid fiber reinforced.
- a fiber reinforcement and a fabric or braid can be used to reinforce the plastic, wherein the fabric or braid can also be formed for example of glass fibers, basalt fibers, carbon fibers or aramid fibers.
- the material used for the inlet body and optionally the pressing element is a technical thermoplastic which comprises a polyamide (PA), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polycarbonate (PC), polyoxymethylene (POM), polypropylene (PP ) or acrylonitrile-butadiene-styrene (ABS).
- PA polyamide
- PET polyethylene terephthalate
- PBT polybutylene terephthalate
- PC polycarbonate
- POM polyoxymethylene
- PP polypropylene
- ABS acrylonitrile-butadiene-styrene
- ABS acrylonitrile-butadiene-styrene
- a well-suited material is thus for example polyamide, in particular fiber-reinforced, e.g. glass fiber reinforced polyamide.
- Polyamides are among the most important engineering thermoplastics. They are tough materials with high strength and rigidity, excellent impact strength and good abrasion and wear resistance. Polyamides have a relatively low glass transition temperature and are therefore often reinforced with glass fibers. In addition to the increase in strength and modulus, this increases the continuous use temperature significantly.
- the present invention also provides a method according to claim 13 for producing a device for draining water from flat roofs, balconies, patios or other water-bearing surfaces, which device may have the features described above.
- the inlet body are produced by injection molding and the bolt or the screw thereby placed in the production tool for the inlet body and molded with the thermoplastic material, or
- a self-tapping screw can be used, which - is screwed directly into the inlet body - from the side facing the press ring - directly.
- the invention also provides a catcher for a device for draining water from flat roofs, balconies, terraces or other water-leading surfaces, preferably a device of the type described above.
- the catcher is placed on an inlet body of the device. It has a number of evenly spaced, circumferentially spaced, disc-shaped, vertical slats that open radially inwardly into a plate-shaped central part. At the radially outer edge of the plate-shaped central part, a circumferential edge is formed, so that an inlet cross section of the collecting basket is reduced.
- the slats can be connected to each other at their outer upper ends via a circumferential outer ring.
- the central part, the fins and possibly the outer ring may be formed as a one-piece injection molded part.

- FIGS. 1 to 5 show different views of a roof drain 1 according to the invention.
- the roof drain 1 is provided for installation in a designated opening in a flat roof (not shown). It comprises an inlet body 2 with a ring-shaped or dish-shaped collar edge 20 which, in the installed state of the roof drain 1, rests on one of the layers which form the roof structure. In the case of a warm roof, the collar edge 20 may rest in particular on an insulation, in the case of a cold roof directly on the roof skin.
- a pipe socket 21 connects, which penetrates the roof surface and forms an inlet opening 22 and an outlet opening 29 for discharging the collected water.
- a connecting foil or web 7 eg of bitumen or FPO
- a seal 8 are braced against the inlet body 2 by means of a press ring 6.
- the connection film 7 is cut out in the area of the inlet.
- the reference numeral 30 designates mounting holes on the outer circumference of the inlet body 2, the reference numeral 31 radially extending reinforcing webs on its underside.
- Inlet body 2 and press ring 6 are configured in the present example of glass fiber reinforced polyamide.
- this engineering thermoplastic By using this engineering thermoplastic, the strength and the rigidity of these components are increased, and the construction height of the roof drain 1 can be reduced accordingly.
- another engineering thermoplastic could be used, even in unreinforced form, or a thermoplastic composite whose base does not necessarily have to be a engineering thermoplastic.
- the press ring 6 of the glass fiber reinforced polyamide has a greater material thickness (ie thickness, dimension in the vertical direction in the drawings) than conventional press rings, especially as conventional metallic press rings.
- the pressing ring 6 has the necessary strength to clamp the connecting foil 7 and the seal 8 between the press ring 6 and the inlet body 2, and thus to produce a firm bond for pressing the seal 8.
- Inlet body 2 and press ring 6 can be screwed with tightening torques of> 20 Nm.
- inlet body 2 and pressure ring 6 are screwed together at eight evenly spaced over the circumference of the roof drain 1 positions.
- the screw is realized by means of stud bolts 10 and associated nuts 11.
- the stud bolts 10 are here self-tapping screws that have been factory pre-assembled from the side facing the press ring 6 in the inlet body 2 to facilitate the installation of the roof drain 1 on site.
- the glass fiber reinforced polyamide plastic used for the inlet body 2 ensures a particularly good grip of the screws.
- One possible embodiment for the self-tapping screws are so-called double bolts.
- stud bolts can also be placed directly in the production tool of the inlet body 2 and molded with plastic, so that the manufacturing step of mounting the stud in the inlet body 2 is omitted.
- threaded pins can be embedded in a conventional manner by means of ultrasound or heat transfer into the inlet body 2, or it can be threaded inserts embedded in the manner in the inlet body 2 and studs are then screwed into these threaded inserts.
- the stud bolts 10 protrude from the inlet body 2 in the direction of the press ring 6, and in the press ring 6 corresponding through holes 62 are formed through which the stud bolts 10 are passed, then from the inlet body 2 side facing away from the press ring 6 by means of nuts 11th to be clamped against the inlet body 2.
- this Roof drains with Aufstauringen for emergency drainage are known per se; they are installed on roof surfaces at regular intervals for the safe drainage of rain during heavy rainfall events and should only develop their mode of action during heavy rainfall events.
- this Aufstauring can also be made of a technical thermoplastic, in particular a glass fiber reinforced polyamide, and preferably made of the same material as the inlet body 2.
- Figure 6 shows an exemplarynnenstauring.
- the roof drain also includes a catcher 4 for foliage, gravel and the like, which is placed on the inlet body 2.
- a catcher 4 for foliage, gravel and the like which is placed on the inlet body 2.
- two of the eight studs 10 have a much greater length. These longer studs are marked with 10 'in the drawings.
- a pipe socket 21 is formed, which therefore also consists of the glass fiber reinforced plastic and on the mounted state of the roof drain 1, a drain pipe, e.g. a down pipe (not shown) is connected.
- a pipe thread for example a 2 "thread, is formed on the free end of the pipe socket 21.
- the pipe thread can be molded directly onto the inlet body 2 in the injection molding tool
- it can be made of polyethylene (PE).
- PE polyethylene
- the pipe socket 21 has a threadless section.
- a surface heating By attaching a surface heating, the safe operation of the roof drain 1, even in winter months, can be ensured. It prevents the roof inlet from freezing in the event of freezing rain or snow.
- the inlet body 2 has a substantially annular shape in plan view. On the outer circumference of the inlet body 2, an outer annular surface 23 (see Figure 5) is formed, which points to the leaf trap 4 in the assembled state of the roof outlet 1. Radially within this first part surface 23, the inlet body 2 has a likewise annular and horizontally extending support surface 24 for the seal 8.
- the support surface 24 is recessed relative to the outer annular surface 23. It extends between a radially outer shoulder 25 and a radially inner shoulder 26, whose height in the present embodiment corresponds approximately to the material thickness of the seal, which may be for example about 3 mm. To achieve the lowest possible height, the seal 8 is thus completely embedded in the inlet body here.
- the seal 8 may be only partially embedded in the inlet body, wherein the shoulders 25, 26 but should be at least as high as half the material thickness of the seal. From the outer annular surface 23 of the surface of the inlet body 2 extends downwardly inclined towards the outer shoulder 25, whereby the height difference between the outer annular surface 23 and the bearing surface 24 for the seal additionally increases. The difference in height between the surface 23 of the inlet body and the bearing surface 24 formed by the annular recess is marked "H" in FIG. It is greater than the material thickness of the seal, so that in the mounted state and the press ring 6 can be at least partially embedded in the inlet body 2.
- the squeeze ring would be a flow obstruction if it were not buried in the inlet body 2: the rainwater would be dammed up to the height of the squeeze ring (in an exemplary embodiment, about 10 mm) before it could be removed, which in turn would mean that rainwater would be constantly present standing on the roof. By at least partially sinking the press ring entering rainwater in the roof drain, however, flow almost unhindered in the direction of the downpipe.
- the transition between the radially inner shoulder 26 and the pipe socket 21 of the inlet body 2 is formed by an inclined surface 27 which is inclined downwards in the direction of the pipe socket 21, and a rounded transition region 28.
- the inclined surface 27 is inclined at an angle of 17.5 degrees with respect to the horizontal, and the rounded transition portion 28 is formed with a radius of 10 mm.
- the pressing ring 6 is designed substantially annular and has in the central region via a passage opening 61, which is aligned in the mounted state of the roof drain with the outlet opening 29 of the inlet body 2 and through holes 71, 81 of the terminal film 7 and the seal 8. Both on its outer circumference as well as at the beginning of the through-opening 61, the pressing ring 6 has a rounded shape, in the present example with radii of 9 or 9.5 mm.
- the geometry of the leaf trap 4 is optimized for flow.
- the leaf trap 4 is formed of a number of evenly spaced, circumferentially spaced, disc-shaped, vertical slats 42, which open radially inwardly into a plate-shaped central portion 46.
- all slats 42 are connected to each other at the outer upper edge via a peripheral outer ring 44.
- Middle part 46, fins 42 and outer ring 44 are formed in the present embodiment as a one-piece injection molded part.
- the plate-shaped central part 46 forms in the central region a downwardly projecting thickening 47.
- the volume is reduced within the leaf trap 4, whereby the roof drain 1 faster in full filling and can build the necessary negative pressure to start the dewatering process.
- the rainwater flowing into the roof outlet 1 is deflected by the central thickening 47 in the direction of the outlet opening 29 in the inlet body 2 and thus the downpipe connected there.
- FIG. 7 shows a slightly modified embodiment of an inlet body 2 '. It differs from the inlet body 2 described above and shown in Figures 1 to 5 on the one in the positioning of the four mounting holes 30 ', which - unlike the inlet body 2 - are offset angularly with respect to the eight studs 10 here: In the circumferential direction of the inlet body 2, each attachment hole 30 'is disposed between two stud bolts 10.
- the inlet body 2 'differs from the inlet body 2 in that it is provided with a circumferential collar 32 on its outer circumference.
