Description

The present invention relates to a Drainage channel made of metal, preferably made of Stainless steel or galvanized sheet steel, in particular from Armco Sendzimir galvanized Sheet steel, with a substantially U-shaped Cross section, in the area of the U-web and / or in Area of the two U-legs drain openings are punched out, the two U-legs across, preferably at right angles, to the outside as a support are bent for at least one grate and to the two U-legs height adjustment devices are attached.

Such drainage channels are used for facades, Flat roofs, green roofs, patios or the like used to drain surface water. Around the drainage channels to the water level of the Making surface water adaptable is at conventional drainage channels one Height adjustment device for the storage of the Drainage channels provided.

Such height adjustment devices are in turn in the form of known drainage channels adjustable screw feet executed on the Drainage channels are permanently attached. At the Cutting prefabricated drainage channels to length dimensions required in practice, for example about 1,000 millimeters or about 1,500 millimeters it turned out to be extremely disadvantageous, that the fixed height adjustment devices not adaptable to the dimensions of the drainage channels are.

A drainage channel is known (DE 32 14 442 C2) for with a water-permeable covering provided flat roofs, consisting of one in this Cover provided groove-shaped recess that by one on a height-adjustable support arranged rust covered and covered by water-permeable side boundary walls is stiffened, the support from two in Angular profiles kept apart consists of the protruding legs of im Distance from each other, in cross section U-shaped brackets at the desired height are set, and being the side Boundary walls through on the outside of this Legs arranged pinhole are formed.

The protruding legs of the cross section U-shaped brackets have slot-like recesses through which screws extend which lead to the Set the angle profiles in the desired one Serve at high altitude, with the grille on the Angle profiles using a clamp bracket is set.

The well-known system for height adjustment has proven itself insofar as not unproblematic in that it doesn't the dimensions of the drainage channels can be adjusted so that the well-known drainage channel, for example depending on the respective spatial Conditions flexibly and individually adjustable is.

It is a gutter body to form one Trough across the surface of structures discloses (DE 44 29 457 A1), in which at the top parallel cover parts held a cover grate is and in which also on the side wall parts longitudinally offset fixable adjustment elements of the Gutter body are arranged to Horizontal adjustment on the channel body are arranged longitudinally displaceable. Furthermore can use the adjustment elements for height adjustment can also be adjusted in height and as a U-bracket be trained in their side legs have vertical slots open on one side.

It is true of this well-known drainage channel a possibility of height adjustment is provided, however, it is constructed in many parts, complicated and time consuming to use and only under difficult conditions can be readjusted.

Based on the disadvantages listed above and shortcomings of the known Drainage channels are in accordance with the present invention based on the task of a drainage channel for To make available at which the Height adjustment devices can be released in a simple manner attached and to the grid of the drain openings can be adjusted.

This task is accomplished through a drainage channel according to the preamble of the main claim by its characteristic features according to the invention solved that the height adjustment on the Drainage channel detachable using at least one Plug connection can be determined via insertion holes and that the insertion holes in a given Grids are arranged along the drainage channel.

The drainage channels that can be cut to length according to the invention are of substantially U-shaped cross-section Sheets, for example made of corrosion-resistant Steel sheets or made of high quality stainless Stainless steel sheets made to long-term Ensure functionality. Here are on lower section of the U-bridge or the two U-legs preferably as elongated holes in Trained longitudinal direction of the drainage channel Drain openings punched in, which lead to a removal of the in entering the drainage channel Cause surface water.

On the two U-legs can cross, preferably outwardly extending supports for an advantageously hot-dip galvanized grate - For example, a flat bar parallel grate, one Grating, an elongated perforated sheet, one Perforated sheet metal grate (such as copper) or one Parallel rod grate (e.g. made of brushed stainless steel or made of polished stainless steel) - arranged, which the Drainage channel covered and ingress of Foliage, dirt or other drainage openings potentially blocking substances. The for example, nose-shaped supports serve in this context as a safeguard for that the grate lies securely and immovably.

The drain openings are preferably according to one certain grid arranged on the U-webs what regarding a cut to the length of the building necessary measure proves to be appropriate.

To have a good effect of the drainage channel over their to allow entire length, it turns out to be advantageous to use the height of the drainage channel Height adjustment devices to the local Adapt conditions. such Height adjustment devices have so far been used known drainage channels with the U-legs firmly connected, for example by a Screwing or by welding what with the conventional tools available on site only with great difficulty or not possible at all was.

According to the invention are therefore on the U-legs Insert holes provided in which the Height adjustment devices using at least one Detachable and relocatable plug connection to the U-legs can be fixed. Even with extreme ones Bumps and / or obstacles as well as on site cut pieces can therefore be cut Height adjustment. at intervals of for example, about a hundred millimeters with just move two simple steps; it there is practically no waste, because the Remnants can be reused.

If the drainage channel is bent across Support for the foliage and dirt trap serving grates, it turns out to be expedient, in these bent supports To provide adjustment openings which are arranged so that they are in the grid with the insertion holes match and setting up the Height adjustment devices using a tool, for example by means of a screwdriver enable above.

In this context, the person skilled in the art becomes particularly concerned appreciate that the height adjustment in Contrary to conventional drainage channels is convenient, simple and easily accessible from above, without disassembling parts of the drainage channel would have to be because the respective adjustment head or the respective adjustment screw is also unhindered through the openings of gratings or Parallel grating accessible.

Here, the height adjustment device in a thread is particularly preferred on that in operative connection with the respective Adjustment head or with the respective adjustment screw can stand and by rotating the respective Adjustment head or the respective adjustment screw with a conventional screwdriver Height adjustment device and thus the Drainage channel changed continuously and to the be adapted to local conditions can.

Thus, the drainage channel is always piece for The height of the piece can be flexibly adjusted so that for example when an adjacent one settles Roof structure without problems even after years Disassembly of the aforementioned grate types readjusted can be. Furthermore, the drainage channel by means of the insertion holes in an expedient manner adjustable in the longitudinal direction.

Furthermore, the foot part of the Height adjustment device and / or the support according to a particularly preferred embodiment of the present invention from an envelope non-slip material, e.g. plastic, such as rubber or neoprene. This not only provides excellent protection from Damage or required against pollution, but also those for example in the floor area arranged drainage channels required Reliable slip resistance guaranteed.

If the drainage channel is particularly preferred Ways to be further developed are not just those Insertion holes, but also the adjustment openings and, if necessary, also for the incoming Drainage openings provided in a water predetermined grid along the drainage channel arranged.

For easier connection of cut to length, for example, even straight parts of the Drainage channel it proves to be advantageous with at least one of the two ends of the U-web to provide at least one notch in which a preferably double U-shaped connecting element for Connecting two drainage channels is insertable or on which a preferably double U-shaped Connecting element for connecting two Drainage channels can be plugged on.

Through these connecting elements or dome elements the drainage channels are already at the channel joint with the basic orientation in the horizontal direction and stabilized in the vertical direction, one aligned, bend and torsion-free as well as quick laying of the drainage channel is guaranteed, depending on the track length the construction work by about Double to triple increase; this saves time and especially high labor costs, being the assembly due to the simplicity and clarity of the system presented here also for unskilled Auxiliary staff rationally and without any problems is feasible.

Depending on the sealing structure and the adjacent surface, for example asphalt or Pavement, can be used for the drainage channel according to the present invention variable heights of each for example, about 73 millimeters to about 103 Millimeters, from about 93 millimeters to about 143 Millimeters or from about 113 millimeters to about 183 millimeters with three standard widths of for example about 150 millimeters, about 200 Millimeters or about 250 millimeters reach.

The insertion holes for the height adjustment devices are preferably as vertical slots trained in the locking hooks attached to the Height adjustment devices are attached, can intervene. In this context it can turn out to be useful, the locking hook after insertion into the vertical slots Locking tabs that go into the locking hook can be introduced and intervene in them lock.

The drainage channel can not only be in the form of a straight, not curved part. Depending on the structural conditions, but also of design preferences Drainage channel in an advantageous manner Form of a preferably rectangular corner piece with for example five or six Height adjustment devices and / or in the form of a T-piece and / or in the form of a cross piece be trained.

In the areas of the drainage channel that are free end, that is not to another Drainage channel or to another Connect drainage component, it can optical reasons and / or for security reasons be recommended an end cap or a bumper to attach to the end of the drainage channel to provide adequate completion of the Form drainage channel.

According to a particularly inventive embodiment the present drainage channel is at least one end of the drainage channel to at least one breakout outlet, preferably rectangular, especially roughly square as a terrace kit trained gully box laterally offset and / or connectable in the middle. Here is a Slot drainage with the usual gully sizes corresponding recesses.

In a preferred embodiment, the Terrace kit, the height of which is essentially should correspond to the drainage channel, one four-sided connection possibility, which as a departure trained connection openings as a result of Pretreatment, for example using a Laser beam, in a particularly simple manner must be broken out.

If you compare the drainage channel according to the present invention with conventional, from the State-of-the-art drainage channels, see becomes the specialist as well as the practitioner in particular appreciate that due to the compact Construction with a continuous channel floor a quick Runoff of surface water as well as a problem-free Cleaning is possible and the need for one additional material and assembly costs for additional, unstable and loose gravel stop strips omitted, which has a cost-reducing effect.

In this context, also favorably occur no sharp edges or protruding parts, no cutting work for height adjustment and none open butt joints.

Flow itself through the continuous channel floor extreme amounts of rain quickly and specifically for Drainage point; the risk of congestion is also through Icing significantly reduced in winter. On another great advantage of the essentially closed channel construction is the Ease of maintenance, removing the dirt wedged less and the Drainage channel according to the present invention also easier to clean.
