Description

technical field

• wobei die bezüglich der Füßchen entgegengesetzt angeordneten Enden der Stützen an einem quer zur Erstreckung der Entwässerungsrinne vorgesehenen Bügel festgelegt sind und
• wobei zwischen jedem Seitenteil und den beiden Enden des Bügels eine an diesen festgelegte, parallel zum angrenzenden Seitenteil (bezüglich des Abstands vom Rinnenboden) höhenverschiebbare Rinnenvertiefung angeordnet ist

(vgl. DE 20 2005 001 609 U1 ).The present invention relates to a generic drainage channel with a U-shaped profile, having a web as the channel bottom and legs adjoining it on both sides as side parts, with supports with height-adjustable feet that are detachably fixed to the ends of the supports,

• wherein the opposite ends of the supports with respect to the feet are fixed to a bracket provided transversely to the extension of the drainage channel and
• between each side part and the two ends of the bracket there is arranged a channel recess which is fixed to the bracket and is vertically displaceable parallel to the adjacent side part (with respect to the distance from the channel bottom).

(see. DE 20 2005 001 609 U1 ).

State of the art

Such drainage channels are used in a variety of embodiments (see, for example EP 0 980 942 A2 ). These have proven themselves. However, the small foot attached to the side of the drainage channel takes up space at the end of the supports, so that either appropriate space must be provided on the ground for the channel, or only a narrower drainage channel can be used. In addition, the requirement of changing the volume to be taken up cannot be met with the known solution.

There are also drainage channels that have a large channel cross-section in a U-shape, even with variable height adjustment. Such known gutters with a large gutter volume have a continuous gutter bottom. In the case of a channel with a continuous channel base lying on the subsurface, unevenness below the flat channel body - for example joints of bitumen sealing membranes overlapping the longitudinal direction of the channel, which can account for a height offset of up to 1.5 cm - can cause so-called wobbling. This problem occurs with all known U-shaped channels.

In the DE 20 2006 009 404 U1 discloses a drainage channel whose channel bottom has openings for the footrests. In the EP 1 191 148 A1 discloses a drainage channel whose channel bottom is adjustable in height by turning the foot.

Description of the present invention: task, solution, advantages

Proceeding from the disadvantages and shortcomings described above and considering the outlined prior art, the object of the present invention is to provide a generic drainage channel according to the preamble of claim 1, which is adjustable with regard to the volume of water to be drained.

• dass der Rinnenboden Durchlässe für die Stützen der Füßchen aufweist und
• dass jede Stütze im Bereich der Durchlässe am Rinnenboden höhenverstellbar zu den Füßchen festlegbar ist.

Vorteilhafte Ausgestaltungen und zweckmäßige Weiterbildungen der vorliegenden Erfindung sind in den abhängigen Ansprüchen gekennzeichnet.In the case of a generic drainage channel according to the preamble of claim 1, this object is achieved according to the invention by its characterizing features, i.e. by

• that the channel bottom has passages for the supports of the feet and
• that each support in the area of the passages on the channel floor can be fixed in a height-adjustable manner to the feet.

Advantageous refinements and expedient developments of the present invention are characterized in the dependent claims.

With the present invention, it is possible to always use the drainage channel with the optimum width and to easily adjust the height on the one hand and also with regard to the volume of water to be drained off on the other hand, even in the installed state.

The height adjustments are particularly easy if each support has an external thread and each bracket has an internal thread adapted to it. If each support in the area of the passages on the channel floor is adjustable in height with respect to the feet, the distance from the floor to the drainage channel and its depth for the water volume can be set separately from one another in a simple manner.

In an advantageous embodiment of the present invention, the thread bases do not stand on the U-shaped channel body, but are arranged underneath it. The plates (threaded feet), which can be made of plastic, for example, stand directly and securely on the substrate (sealing).

The channel body can be arranged to be adjustable in height in an exemplary adjustment range of about ten millimeters. This type of construction enables local unevenness in the subsoil to be compensated for by the U-shaped channel bottom (this unevenness can be up to ten millimetres).

In contrast to the prior art, in the case of the present invention the channel body does not have to be lined in a costly manner in order to prevent the drainage channel from tipping.

Advantageously, the brackets with the threaded feet can be displaced in the longitudinal direction, that is to say in the direction of the longitudinal extent of the drainage channel, if necessary.

In an expedient embodiment of this inventive idea, the support has at least one taper adjacent to the foot, which is followed by the external thread, and the passages in the channel base are designed as a keyhole-like stepped slot with two different widths, with only the taper of the support in the built-in Condition fits into the narrower part of the slotted hole and the wider part of the slotted hole is only used to insert the support during assembly.

It is particularly easy to adjust the height when installed using at least four threaded feet if the free end of the support is provided with an Allen key.

As an alternative to inserting the threads into the bracket by means of additional small angles, according to a preferred embodiment of the present invention, riveting nuts, in particular standardized riveting nuts, can be used for the bracket - for the purpose of forming a thread for receiving and height-adjusting the thread bases, for example with a Thread diameter M10. Conveniently, these rivet nuts can be made of stainless steel.

If each channel recess of the drainage channel has one or two recessed slots, possibly extending to the edge of the channel recess, through which the correspondingly shaped end pieces are passed at one of the two ends of the bracket and project beyond them, and each side part is adapted to the slots of the channel recess and the in addition, straight slots accommodating projecting corner pieces, the channel recess and the drainage channel can be guided and fixed to one another in a height-adjustable manner in a simple manner.

In order to be able to cut the drainage channel according to the invention to the desired length on the construction site, the stepped and straight elongated holes as well as the slots are arranged symmetrically on both sides of the longitudinal center plane of the channel base, as well as in the direction of the extension of the drainage channel to a specified extent or Module repeatedly provided.

In order to rule out what is known as tipping, the plates of the threaded feet can be arranged below the bottom of the channel. Due to the selective support of the plates, in particular four or six support points per channel body, unevenness can be compensated very easily and without great effort (such as selective lining to compensate for height differences below the channel floor).

A maximum channel volume is ensured by the construction.

The displacement (in height) of the channel bottom part to the top continuous, in particular two, bearing profiles can be limited by the taper in the threaded feet. The bottom of the channel always remains as close to the ground as possible.

This interaction of maximum channel volume and optimal compensation of unevenness in the subsoil is new, because conventionally, either the drainage channels optimally compensate for unevenness in the subsoil with a relatively small channel volume (elevated channel body) or ensure a relatively large channel volume, with the channel base directly on the Subsoil, such as on a flat roof seal, rests, combined with the disadvantage of tipping on unstable subsoil.

The channel according to the present invention can be composed of several individual parts i.e. detachably assembled / assembled in several parts:
Depending on the installation situation, the two upper side parts can be exchanged according to the requirements of the channel cross-section. The special profiles are then hooked into the two crossbars and riveted or screwed. On the other hand, conventionally, the channel body has to be completely manufactured to adapt the channel cross-section to the installation situation.

An alternative to the riveted or screwed connection between the bracket and the side parts can preferably consist in realizing the connection between the bracket and the side parts by mutual displacement of the individual parts (ie not by means of riveting or screwing); the position of the components is then secured via the threaded feet to be finally assembled.

The modular design of the drainage channel according to the present invention allows for an extremely varied design scope. The finished part is made up of individual system components. With manageable individual elements, the drainage channel according to the present invention can be adapted to structural conditions, i.e. the channel can be optimally adapted to the structural situation or the design planning, so that according to the invention a standardized basic system/channel system can be made available for many areas of application .

• in sich verschiebliche Seitenwandelemente --> variierbares Aufnahmevolumen;
• (zum Beispiel mittels Imbus-Kurbeln) höhenverstellbare Füßchen --> Wippeln der Rinne an Stößen / Versetzungen ausgleichbar.

An essential component of the drainage channel according to the present invention is the variable and readjustable base body, with two setting options that can be combined with one another:

• sliding side wall elements --> variable storage volume;
• (e.g. using Allen cranks) Height-adjustable feet --> teetering of the channel on impacts / offsets can be compensated.

Those skilled in the field of drainage channels will particularly appreciate that the entire height of the channel is available for the drainage of water, especially rainwater; the higher the drainage channel is set, the larger the volume of the drainage channel.

For example, sheet metal, in particular galvanized sheet steel, or stainless steel can be selected as the material for the drainage channel.

The drainage channel according to the present invention can be used for preferably flat roofs, roof terraces, balconies or the like.

In order to avoid superfluous repetitions, the following explanations relate to the configurations, developments, features and advantages of the present invention

• unless otherwise stated -
• both on that basis Figures 1A to 1D illustrated first embodiment of a drainage channel 10
• as well as on the basis Figures 2A to 2D illustrated second embodiment of a drainage channel 10 '
• as well as on the basis Figures 3A to 3D illustrated third embodiment of a drainage channel 10"
• as well as on the basis Figures 4A and 4B illustrated fourth embodiment of a drainage channel 10 ‴.

In the Figure 1C The drainage channel 10 shown is made of sheet metal and has a U-web as the channel bottom 101 and provided with U-legs adjoining it on both sides as side parts 102 for preferably flat roofs, roof terraces, balconies or the like. The bottom of the channel has passages 104, for example in the form of a so-called keyhole punch.

Through the passages 104 are passed supports 201 of the drainage channel 10 releasably fixed and height-adjustable feet 202 at the ends of supports 201 (cf. 2 ). Each support has an external thread 203 for height adjustment.

The opposite ends of the supports 201 with respect to the feet 202 are fixed in a height-adjustable manner on a bracket 30 provided transversely to the extension of the drainage channel 10 by means of an internal thread 301 adapted to the external thread 203, the free end of the support 201 being fixed with an Allen key for height adjustment in the installed state can be provided.

Between the two ends 302 of the bracket 30 and the side parts 102 of the drainage channel 10, a channel recess 40 is arranged during assembly, each of which is preferably fixed to the bracket 30 by means of a rivet or screw 304, the thread diameter of which is M5, for example.

The ends 302 of the bracket 30 expediently have pockets 303 into which one or two recessed slots 403 extending to the edge of the channel recess 40 (cf. Figure 1A ) intervene.

The two ends 302 of the bracket 30 protrude over the side surface of the channel recess 40, with the slots 403 and the straight elongated holes 103 being arranged at right angles to the level of the channel bottom.

The adjustment brackets 30 are thus connected to two hooks or projections 302 via suitable cutouts 103 and 403 in the side parts 102 and 40, respectively. The additional rivet or screw 304 secures this connection, allowing the fabricator to variably shorten the length of the drainage channel 10, 10', 10", 10‴ on site.

For this purpose, the adjustment brackets 30 are simply moved along the longitudinal extent of the drainage channel 10, 10', 10", 10‴. The hooks 302 of the adjustment brackets 30 protrude by about two millimeters.

This supernatant is used to connect the upper part 40 and the lower part, ie the U-profile 101, 102 of the channel body. Long, parallel slits 103 and 403 allow mutual displacement of the channel parts relative to each other for the purpose of height adjustment.

During assembly, these projections 302 are accommodated in straight elongated holes 103 adapted to the slots 403 of the channel recess 40 and are displaceably arranged in these between their two ends parallel to the adjacent side part 102 and thus vertically displaceable with regard to the distance between the channel bottom 101 and the ground.

For this purpose, each support 201 is expediently designed to be adjustable in height to the feet 202 in the area of the passages 104 on the channel base 102, the support 201 having at least one taper 204 adjacent to the feet 202, to which the external thread 203 connects.

The passages 104 in the bottom of the channel are designed as keyhole-like stepped slots with two different widths, with the taper 204 of the support 201 only fitting into the narrower part of the slot when installed and the wider part only for inserting the support 201.

Each channel recess 40 is provided on the side facing away from the channel bottom 102 with a support 401 for a (usual, for reasons of clarity of the representation only in Figure 4A and in Figure 4B shown) gutter cover 50 provided. The channel cover 50 can be a grating, in particular a mesh grating, a perforated grating, a longitudinal bar or linear grating, a transverse bar grating and/or a corner grating.

In order to be able to cut the drainage channel according to the invention to the desired length on the construction site, both the stepped elongated holes 104 and the straight elongated holes 103 as well as the slots 403 are arranged symmetrically on both sides of the longitudinal center plane of the channel bottom 101, as well as in the direction of the extension of the drainage channel 10 provided repeatedly in a predetermined amount or module.

According to the second exemplary embodiment Figures 2A to 2D the threads are not made by means of additional small angles 305 (cf. first exemplary embodiment according to Figure 1B ) inserted into the bracket 30; rather, for simplification and for the purpose of forming a thread for receiving and adjusting the height of the thread bases, two elements 306' are used in each bracket 30.

According to the third exemplary embodiment Figures 3A to 3D these two elements are standardized 306" rivet nuts made of stainless steel, which have a thread diameter of M10, for example.

From the representations shown for the fourth embodiment Figure 4A and the Figure 4B one goes to the riveted or screwed connection 304 (cf. Figure 1C ) alternative embodiment for the connection of the bracket 30 with the side parts 40:
Unlike the first embodiment (cf. Figure 1C ) no additional rivet or screw 304 is required to connect the individual parts; Rather, the connection is realized by mutual displacement of the individual parts, and the position of the components is secured via the threaded feet 202 to be assembled afterwards.

This not only requires improved anti-flooding protection, but also advantages both during production and during later assembly on site, for example at the construction site.
