Description

Technical area

The present invention relates to a generic drainage channel with a U-web as a channel bottom and adjoining U-legs on both sides as side parts with detachably fixed, height-adjustable feet at the ends of columns according to the preamble of claim 1.

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 feet placed on the side of the drainage channel take up space at the end of the columns, so that either sufficient 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 recorded with the known solution can not be achieved.

Furthermore, there are drainage channels, which have a large channel cross-section in U-shape even with variable height adjustment. Such known gutters with large gutter volume have a continuous gutter bottom. In the case of a gutter with a continuous gutter bottom lying on the ground, so-called tipping may occur in the case of unevenness beneath the surface-lying gutter body, for example transversely overlapping joints of bitumen waterproofing membranes, which may make up a height offset of up to 1.5 cm. This problem occurs in all known grooves in U-shape.

Presentation of the present invention: object, solution, advantages

Based on the disadvantages and inadequacies set out above and in appreciation of the prior art outlined, the present invention has the object to provide a generic drainage channel according to the preamble of claim 1, which is adjustable in terms of the volume of water to be discharged.

• dass der Rinnenboden Durchlässe für die Stützen der Füßchen aufweist,
• dass die bezüglich der Füßchen entgegengesetzt angeordneten Enden der Stützen an einem quer zur Erstreckung der Entwässerungsrinne vorgesehenen Bügel festgelegt sind und
• dass 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.

This object is achieved in a generic drainage channel according to the preamble of claim 1 according to the invention by its characterizing features, thus solved,

• that the channel bottom has openings for the supports of the feet,
• that with respect to the feet opposite arranged ends of the supports are fixed to a transversely to the extension of the drainage channel provided strap and
• that between each side part and the two ends of the bracket is fixed to this, parallel to the adjacent side part (with respect to the distance from the channel bottom) höhenverschiebbare channel recess is arranged.

Advantageous embodiments 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 in optimum width and easy to adjust in height on the one hand and also with regard to the volume of water to be discharged, even when installed.

The height adjustments are particularly simple if each support has an external thread and each bracket has an internal thread adapted thereto. If each support in the region of the passages on the channel bottom height adjustable with respect to the feet can be fixed, so the distance bottom to drainage channel and its depth for the volume of water can be adjusted separately from each other in a simple manner.

In an advantageous embodiment of the present invention, the roots are not on the U-shaped channel body, but are arranged below it. The plates made of plastic (thread feet), for example, can be placed directly and safely on the surface (sealing).

The gutter body may be slidably disposed in height in an exemplary adjustment range of about ten millimeters. This type of construction makes it possible to compensate for occasional unevenness in the ground through the U-shaped channel bottom (these irregularities can be up to ten millimeters).

Unlike in the prior art, the gutter body in the present invention must therefore not be elaborately relined to avoid tipping the drainage channel.

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

In an advantageous embodiment of this inventive concept, the support, adjacent to the feet on at least one taper to which the external thread connects, and the passages in the channel bottom are formed as a stepped slot with two different widths keyhole-like, the taper of the support in the installed state fits only in the narrower part of the slot and the wider only for insertion of the support during assembly.

The height adjustment, which can be accomplished via at least four threaded feet, is particularly simple when installed, provided the free end of the support is provided with an Allen key.

As an alternative to the insertion of the thread in the bracket by means of additional small angle, according to a preferred embodiment of the present invention in the bracket - for the purpose of forming a thread for receiving and adjusting the height of the threaded feet - rivet nuts, in particular standardized rivet nuts, are used, for example with a Thread diameter M10. Conveniently, these rivet nuts may be made of stainless steel.

Having each gutter recess of the drainage channel one or two recessed and possibly reaching to the edge of the groove recess slots through which the corresponding shaped end pieces are passed at one of the two ends of the bracket and projecting beyond, and adapted each side part to the slots of the channel recess and the beyond projecting corner pieces receiving straight slots, so can the gutter recess and the drainage channel in a simple manner to each other height adjustable lead and set.

In order to cut the drainage channel according to the invention to the desired level on the construction site, the stepped and the straight slots and the slots are arranged symmetrically on both sides of the longitudinal center plane of the channel bottom, as well as in the direction of extension of the drainage channel in a predetermined amount or Module repeatedly provided.

To exclude a so-called tilting, the plates of the threaded feet can be arranged below the gutter floor. Due to the punctual support of the plate, in particular four or six support points per channel body, unevenness can be compensated very easily and without much effort (such as punctual relining to compensate for differences in height below the gutter floor).

A maximum channel volume is ensured by the construction.

The displacement (in height) of the gutter lower part to the above-passing, in particular two, support profiles can be limited by the taper in the roots. The gutter floor always stays as close to the ground as possible.

This interaction of maximum channel volume and optimum compensation of unevenness in the subsurface is novel, because conventionally either the drainage channels with a relatively small channel volume optimally compensate for unevenness in the subsurface (elevated channel body) or ensure a relatively large channel volume, with the channel bottom directly on the channel Subsurface, such as on a flat roof seal, rests, combined with the disadvantage of tipping on troubled surfaces.

• In Abhängigkeit von der Einbausituation können die oberen beiden Seitenteile entsprechend der Anforderung an den Rinnenquerschnitt ausgetauscht werden. Die speziellen Profile werden dann in die beiden Querbügel eingehängt und vernietet oder verschraubt. Hingegen muss konventionellerweise der Rinnenkörper zur Anpassung des Rinnenquerschnitts an die Einbausituation komplett hergestellt werden.

The gutter according to the present invention can be composed of several individual parts so assembled / assembled in several parts:

• Depending on the installation situation, the upper two side parts can be exchanged according to the requirement for the channel cross-section. The special profiles are then hung in the two cross brackets 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 may preferably be to realize the connection between the bracket and the side parts via a mutual displacement of the individual parts (not by means of a riveting or screwing); the position of the components is then carried over the finally to be mounted threaded feet.

The modular structure of the drainage channel according to the present invention allows a very varied design freedom. The finished component is assembled from individual system components. With manageable individual elements, the drainage channel can be adapted according to the present invention to structural conditions, that is, the channel can be optimally adapted to the structural situation or design, so that according to the invention a standardized basic system / gutter system for many applications can be provided ,

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

An essential part of the drainage channel according to the present invention here is the variable and readjustable body, with two combinable adjustment options exist:

• slidable side wall elements -> variable absorption volume;
• (for example by means of Allen-cranks) height-adjustable feet -> troughs of the gutter to bumps / displacements compensated.

Those skilled in the drainage gutters will appreciate that the entire gutter height is available for draining the water, especially the rainwater; the higher the drainage channel is set, the greater the volume of the drainage channel.

As a material of the drainage channel, for example, sheet metal, in particular galvanized sheet steel, or stainless steel can be selected.

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

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

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

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

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

Conveniently, the ends 302 of the yoke 30 have pockets 303 into which one or two recessed slots 403 reaching to the edge of the channel recess 40 (see FIG. Fig. 1A ) intervene.

Over the side surface of the channel recess 40, the two ends 302 of the bracket 30 jump out, wherein the slots 403 and the straight slots 103 are arranged at right angles to the plane of the channel bottom.

The adjusting yoke 30 are thus connected to two hooks or projections 302 via matching cutouts 103 and 403 in the side parts 102 and 40, respectively. The additional rivet or screw 304 secures this connection, which allows the fabricator to variably shorten the length of the drainage channel 10, 10 ', 10 ", 10"' in place.

For this purpose, the adjusting yokes 30 are simply implemented only along the longitudinal extension of the drainage channel 10, 10 ', 10 ", 10'". The hooks 302 of the adjustment bracket 30 are in this case about two millimeters.

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

These projections 302 are added during assembly in the slots 403 of the channel recess 40 adapted straight slots 103 and are arranged in these slidable between the two ends parallel to the adjacent side part 102 and thus with respect to the distance of the gutter bottom 101 from the ground.

Appropriately, each support 201 in the region of the passages 104 on the channel bottom 102 adjustable in height to the feet 202 designed configured, the support 201 adjacent to the feet 202 at least one taper 204, to which the external thread 203 connects.

The passages 104 in the channel bottom are formed as a stepped slot with two different widths keyhole-like, wherein the taper 204 of the support 201 in the installed state fits only in the narrower part of the slot and the wider serves only for insertion of the support 201.

Each groove recess 40 is on the side facing away from the channel bottom 102 side with a support 401 for a (usual, for reasons of clarity of illustration only in Fig. 4A and in Fig. 4B shown) channel cover 50 provided. Here, the channel cover 50 can be a grid, in particular a mesh grid, a perforated grid, a longitudinal bar or linear grid, a cross-bar grate and / or a corner grid.

In order to cut the drainage channel according to the invention to the desired level on the construction site, both the stepped slots 104 and the straight elongated holes 103 and the slots 403 are arranged symmetrically on both sides of the longitudinal center plane of the gutter bottom 101, as well as in the direction of extension of the drainage gutter10 provided repeatedly in a predeterminable measure or module.

According to the second embodiment Fig. 2A to Fig. 2D the threads are not by means of additional small angle 305 (see first embodiment according to Fig. 1B ) inserted into the bracket 30; Rather, 30 two elements 306 'are used for simplicity and for the purpose of forming a thread for receiving and adjusting the height of the threaded feet in each bracket.

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

• Anders als beim ersten Ausführungsbeispiel (vgl. Fig. 1C) wird keine zusätzliche Niete oder Schraube 304 zur Verbindung der Einzelteile benötigt; vielmehr wird die Verbindung über eine gegenseitige Verschiebung der Einzelteile realisiert, und die Lagesicherung der Bauteile erfolgt über die abschließend zu montierenden Gewindefüße 202.

From the illustrations shown for the fourth embodiment of the Fig. 4A and the Fig. 4B is a riveted or screwed connection 304 (see. Fig. 1C ) alternative embodiment for the connection of the bracket 30 with the side members 40:

• Unlike the first embodiment (see. Fig. 1C ) no additional rivet or screw 304 is needed to connect the parts; Rather, the connection is realized via a mutual displacement of the individual parts, and the position assurance of the components takes place via the threaded feet 202 to be finally mounted.

This requires not only an improved Aufschwemm-fuse, but also benefits both during production and during subsequent assembly on site, for example, at the site.
