Description

The present invention relates to a channel element with two end faces, wherein each end face is provided for connection to the end face of a further channel element for forming a drainage channel and wherein the channel elements can be connected to each other by connecting means.

Drainage channels are usually formed by adjoining segments or channel elements. It is essential that liquids that are introduced into the drainage channel are transported as completely as possible to a destination, for example to a drain or to a separator.

It is known to grout the joints between two channel elements with a sealant. From the German Patent 195 20 801 It is also known to provide the end faces of the gutter elements with a fit, whereby the sealing means can be filled more effectively into the gap and the inner wall of the drainage gutter is smoother at the transitions between the segments.

It is a disadvantage of such drainage channels that after installation in the ground, the tightness of the joints of the channel elements is not or only with considerable effort verifiable.

It is an object of the present invention to provide a gutter element of the type described above for forming a drainage channel, which can be produced inexpensively, laid simply and quickly and can be checked for tightness.

The object is achieved by a channel element with the features of claim 1. In the dependent claims 2 to 9 advantageous embodiments are given.

The gutter element according to the invention can be assembled with further gutter elements abutting one another to form a drainage gutter. In this case, the two end faces of the channel element are each provided for connection to one of the end sides of the further channel element. According to the invention, the fixed connection between two channel elements is produced by a prefabricated connection means arranged in the region of the two adjoining end surfaces of the two channel elements. The connection means according to the invention provides a firm and tight connection of the channel elements.

It was extremely surprising for the person skilled in the art and it was not to be expected that the gutter element according to the invention would be inexpensive to produce and very easy and quick to lay and the tightness of a drainage gutter from the gutter elements according to the invention could be checked after installation.

The gutter element according to the invention has two end faces, wherein the first end side on the one hand and the second end side on the other hand, for example, may have mutually complementary shapes, so that the joining of two gutter elements with the mutually complementary end faces is possible. However, the end faces can also have any other shapes. They can be shaped differently or, for example, be designed as a flange. Preferably, both end faces of a gutter element have the same shape.

Two adjoining gutter elements according to the invention in the region of the end faces by the prefabricated connection means firmly connected and sealed. For this purpose, the connection means preferably has, on the one hand, a profile seal and, on the other hand, a retaining clip. The prefabricated connection means can be made in one piece or comprise, for example, several individual parts. Prefabricated in the sense of this invention means that connection means is already formed prior to attachment to a channel element and optionally assembled.

The retaining clip according to the invention provides a firm connection between two channel elements. The gutter elements preferably have formations which are to be brought into engagement with the retaining clip such that a positive connection between the retaining clip and the gutter elements with respect to a Movement in the longitudinal direction of the channel elements arises. The person skilled in the art knows numerous possibilities for designing such formations. These may be, for example, undercuts, flanges or grooves.

The retaining clip preferably has a shape that is substantially adapted to the cross section of the channel element, so that the retaining clip is arranged, for example, in the region of the connection point of the channel elements on the outside thereof.

Also preferably, in the region of the side walls of the channel element, particularly preferably in the region of the upper edges of the side walls, first latching means are provided, while second latching means are provided on the retaining clip. The first locking means can be locked with the second locking means.

The skilled person understands that as a rule one of the locking means is resilient and in the other locking means which is rigid, can be latched. For example, the retaining clip could have elastic legs with mutually facing lugs, which preferably press against the side walls of the channel elements and engage in the intended position in depressions or undercuts of the side walls. Likewise, the retaining clip could have rigid second locking means in which resilient first locking means of the gutter elements can be latched.

The gutter elements according to the invention are particularly easy to connect by attaching the connection means. Permanently connectable in the sense of this invention means that the connection of two channel elements is not separated by the loads occurring during the laying or later use of the channel. In particular, the compound is not separated even if the channel is filled with liquid and is not relined, that is, for example, stored on supports.

The retaining clips are preferably detachable again from the channel elements, so that the channel elements can advantageously be separated again.

The retaining clip may be made of any suitable material, preferably of a resilient material. Particularly preferred are the retaining clips made of plastic or metal.

For sealing the gutter elements at the connection point, the connection means preferably has a profile seal. The profile seal is particularly preferably adapted in its shape to the regions of the gutter elements which are to be sealed, for example the mutually facing end faces.

Most preferably, the profile seal has a complementary shape to both end surfaces to be joined, so that a positive connection between the first channel element, the profile seal and a further channel element can be produced.

Such a shape and arrangement of the profile seal or the surfaces to be sealed, which is also referred to as a labyrinth seal is particularly effective and impermeable,

As a sealing material, any suitable material is conceivable. Gaskets of elastomers are preferred. Depending on the use of the drainage channel, for example, numerous variants of the particularly preferred nitrile butadiene rubber (NBR) seal are available to the person skilled in the art. Also particularly preferred are chemical-resistant sealing materials when the drainage channel comes into contact with corresponding substances.

The skilled person understands that the prefabricated connection means ensures both a firm connection of the channel elements with each other, as well as a secure seal. A particular advantage is that the tightness of the connection can be checked immediately after the attachment of the connection means, ie in particular before the environment of the drainage channel is filled with a bulk material or shed.

The skilled person further understands that in a review of the tightness of the compound also special demands on the strength of the compound are made, since the channel is filled for verification, for example, with liquid before it is relined,

The Rinnertelement itself is in any shapes and made of any materials that are known in the art, produced. Depending on the application, it may consist of concrete, mineral casting (polymer concrete), ceramics, metal or plastic, for example. Preferably, the gutter element consists of glass fiber reinforced plastic (GRP) or glass fiber reinforced plastic. Also preferably, the channel element according to the invention has a thin-walled profile.

Another object of the present invention is a channel, a connection means and a method for the construction of a drainage channel of a plurality of channel elements which are connected to each other frontally.

The connection of gutter elements to a drainage channel should be quick and easy. At the same time, the connection should be firm and tight. In particular, in drainage channels, which are provided for the derivation of health or environmentally hazardous substances beyond a verifiability of the tightness would be desirable.

This is made possible by a method for constructing a drainage channel from a plurality of channel elements wherein the channel elements are both firmly connected to each other by a prefabricated connection means, as well as sealed. For this purpose, the connection means has a profile seal on the one hand and a retaining clip on the other hand.

According to the invention, the connection means is preferably pushed onto two channel elements to be connected at the end faces, more preferably from the bottom of the channel elements. In this case, for example, the second locking means of the retaining clip are engaged in the first locking means of the channel elements.

With the method according to the invention, drainage channels can be laid particularly easily and quickly.

Particularly preferably, the drainage channel is tested for leaks, for example, after the channel elements are firmly connected by means of the connection means. When installing the drainage channel into the ground, for example, this is particularly advantageously possible before the drainage channel is embedded in bulk material and / or concrete. The gutter is in this case for example mounted on supports or suspended or suspended, for example by supporting on the surrounding floor area. The gutter is then filled with a liquid. Only if no liquid escapes from the joints, the area is filled under the drainage channel. In particular, in drainage channels in which health or environmentally hazardous substances are to be derived, the control of tightness is of particular importance.
