Abstract

The gutter has a gutter body (1) extending with respect to a slot-like gutter aperture (5) and exhibiting a triangular cross-section. Slotted walls (4) laterally limit the gutter aperture, and supporting flanges (7) support a floor cover and form a ceiling (2) of the gutter body. The slotted walls project from the supporting flanges, and passage apertures (10) for seeping liquid are formed in an edge area of the ceiling of the gutter body. The slotted walls are spaced from each other by a spacer (6), and bow-shaped mounting plates (11) are arranged on two sides of the gutter body.

Description

The invention relates to a slotted channel comprising a chamfered channel profile which has a channel body widened with respect to a slot-like channel opening and receiving limbs for a floor covering which protrude laterally from the slotted walls defining the channel opening.

Slotted channels have a slot-like channel opening in the floor extension, in relation to which the channel body widens toward the channel floor, wherein a floor covering, for example, tiles, can directly adjoin the slot walls delimiting the channel opening if a corresponding attachment of the floor covering to the slotted channel is ensured. For this purpose, using a chamfered channel profile is known (EP 1 719 849 A2) which, on both sides of the slotted walls delimiting the channel opening, has an attachment web bent backward in a fold toward the channel floor and a laterally protruding receiving limb, which originates from this attachment web pressing against the slotted walls, for the floor covering, which ensures ad-vantageous attachment conditions for the floor covering on the slotted channel. However, it is disadvantageous that in the event of a use in moist or wet rooms, for example, in bathrooms, the hazard exists that liquid will seep in along the outer attachment webs pressing against the slotted walls between the floor covering and the slotted channel and will reach the floor structure along the receiving limbs, so that under certain circumstances liquid damage has to be expected, which occurs over longer periods of time and is noticeable, for example, due to detachment of the floor covering from the receiving limbs.

In the case of slotted channels having a channel body which is U-shaped in cross section and is made of concrete, covering the channel body by way of two angle profiles arranged at a distance from one another, the limbs of which, which are adhesively bonded onto the end faces of the longitudinal walls of the channel profile, have passage openings and the limbs of which protruding from these adhe-sively-bonded limbs form the slotted walls, is known (DE 100 28 355 A1). The paving stones of the paved surface to be drained with the aid of such a slotted channel are laid up to the slotted walls, specifically onto a drainage layer, which is in turn applied onto a sealing web, to be able to discharge liquid seeping in via the paving along the drainage layer through the channel body, the top of which forms the passage openings for this purpose. However, the construction expendi-ture, the comparatively low carrying capacity of the channel top, and the circum-stance that a sealing web has to be provided, which cannot prevent the seepage of liquid into the floor structure in the event of damage, are disadvantageous.

Finally, in order to drain sanitary regions, providing a drainage channel is known (DE 20 2009 007 350 U1), which is provided with attachment flanges along the two longitudinal walls of the channel body, via which the channel body is supported on the adjoining screed. These attachment flanges can protrude inward over the longitudinal walls of the channel body and form a protruding attachment web for a floor covering. The distance between these attachment webs is bridged by a perforated cover element. Passage openings for discharging seeping water into the channel body are provided in the section of the attachment flanges protruding inward over the longitudinal walls. Neglecting the faet that this known construc-tion is not suitable for slotted channels, which do not require a top, after all, the attachment flanges welded onto the end faces of the longitudinal walls represent an additional construction expenditure, which is accompanied by the risk of warp-ing due to the welding heat and obstructs the setting of such drainage channels, because backfilling of the channel body is hardly possible.

The invention is therefore based on the object of designing a slotted channel for use in a moist or wet room region so that advantageous construction conditions can be ensured, without having to accept the risk of permanent damage due to seeping liquid in the region of the slotted channel.

Proceeding from a slotted channel of the type described at the outset, the invention achieves the stated object in that the channel top formed by an inwardly di-rected chamfering of the longitudinal body forms the receiving limbs, from which the chamfered slotted walls rise up, and in that passage openings for seeping liquid are provided in the receiving limbs.

Since as a result of these measures, the receiving limbs for the floor covering are not formed by laterally protruding profile sections bent back from the slotted walls, but rather by a channel top chamfered inward in relation to the longitudinal walls of the channel body, liquid penetrating into the region of the attachment joint of the floor covering, for example, outside the slotted walls can be dis-charged via the receiving limbs formed by the channel top into the channel body, because the channel top is provided with corresponding passage openings for seeping liquid. With the aid of the passage openings in the top of the channel body, which is accordingly widened in relation to the slot-like channel opening, the region of the floor covering adjoining the slotted channel can therefore be permanently drained. Since the channel profile is only chamfered and does not have any outwardly protruding webs or flanges, it is not only protected from damage, but rather can also be manufactured easily in a dimensionally-accurate manner, without having to accept strength losses.

The seeping of liquid is to be expected in particular in the region of the attach-ment joint between floor covering and slotted channel. For this reason, it is advis-able to have the receiving limbs descend from the longitudinal walls of the channel body towards the slotted walls and the passage openings to be provided in the transition region from the receiving limbs to the slotted walls. By this measure, seeping water is conducted along the channel top inward up to the slotted walls, where it can drain off through the passage openings into the channel body.

The clearance of slotted channels is delimited on top by standards, to be able to preclude a risk of injury. However, narrow slotted channels are accompanied by cleaning difficulties because of the restricted accessibility. To be able to remedy these difficulties in a simple manner, one or two longitudinal webs can be ar-ranged preferably releasably between the parallel slotted walls, wherein it is to be ensured that the clearance between the longitudinal webs and the slotted walls does not exceed the predefined limits.

The subject matter of the invention is illustrated by way of example in the draw-ing. In the figures:

Figure 1 shows a slotted channel according to the invention in a schematic cross section,

Figure 2 shows this slotted channel in an installed State, also in cross section, but in a smaller scale,

Figure 3 shows an illustration corresponding to Figure 1 of a construction variant of a slotted channel according to the invention, and

Figure 4 shows a further embodiment of a slotted channel according to the invention in an illustration corresponding to Figure 1.

The illustrated slotted channel comprises a chamfered channel profile, which forms a channel body 1, which is substantially widened in relation to a slot-like channel opening 2. The arrangement is made in this case so that the longitudinal walls 4 of the channel body 1 adjoining the channel floor 3 are chamfered inward to form a channel top 5, from which the chamfered slotted walls 6 protrude. To reinforce the slot edges, the slotted walls 6 are bent over like a fold outward to-ward the channel top 5, but this is not required. The distance of the slotted walls 6 from one another is ensured by spacers 7.

As can be inferred from Figure 2 in particular, the channel top 5 forms support flanges 8 for a floor covering 9, which consists of tiles 10 in the exemplary em-bodiment. The support flanges 8 are inclined dropping toward the slotted walls 6 starting from the longitudinal walls 4 of the channel body 1, so that seeping water reaching the support flanges 8 is conducted along the support flanges to the slotted walls 6. Since passage openings 11 for seeping water are provided in the transition region from the support flanges 8 to the slotted walls 6, the seeping water can drain off through the passage openings 11 into the channel body 1. The drainage via the channel top 5 is assisted by the inclination of the support flanges 8.

To set up the slotted channel, it is provided on both sides of the channel body 1 in the region of the longitudinal walls 4 or the channel body 3 with bow-like mounts 12, via which the slotted channel can be supported in relation to an underfloor 13. This support comprises threaded bolts 14, with the aid of which the height and the inclination course of the channel body 1 can be adjusted.

To move the slotted channel, the channel body 1 is adjusted via the threaded bolts 14 supported on the underfloor 13, before a screed 15 is applied to the underfloor 13. Because of the design according to the invention of the channel profile without protruding support flanges, the backfilling of the channel body 1 is substantially facilitated. The screed 15 is drawn off flush with the channel top 5 of the channel body 1, so that a continuous support surface up to the slotted walls 6 protruding from the channel body 1 results, which is formed in the region of the channel body 1 by the channel top 5 used as the support flanges 8. To lay the floor covering 9, firstly a watertight layer 16 can be applied in a typical manner, before the tiles 10 are adhesively bonded on this layer 16 via an adhesive layer 17. This adhesive layer 17 compensates for the slight gradient of the channel top 5. The attachment joints between the floor covering 9 and the slotted walls 6 and the tile joints can then be filled in a conventional manner using a corresponding joint sealant 18.

The slotted channel according to Figure 3 differs from the slotted channel accord-ing to Figure 1 essentially only in that the distance of the slotted walls 6 from one another is enlarged, to be able to provide a longitudinal web 19 between the slotted walls 6, the distance of which to the slotted walls 6 meets the distance re-striction of the slotted walls 6 without longitudinal web, so that no additional cover is necessary. According to Figure 4, the slot width is enlarged once again, wherein two longitudinal webs 19 are provided. In order that these longitudinal webs 19 can be removed from the channel opening 2 for cleaning purposes, they form a modular unit, which rests on transverse webs 20, with the spacers 7 between themselves and the slotted walls 6. Because of the larger channel opening, the receptacle volume of the channel body 1 is enlarged in relation to that of the channel body 1 according to Figures 1 and 2.
