Definitions

  • the present invention relates to a drainage channel with a channel body made of plastic, which has two channel walls that flank a channel base on both sides and each form a support for a cover, wherein the channel body has ribs that each run continuously on the outside from a first support along a first channel wall, over the channel base and a second channel wall to a second support.
  • Such drainage channels are already widely known from the state of the art.
  • JPH 1088650 A A drainage channel with a channel body is known that has continuous external ribs, with additional bottom ribs being provided starting with a central, horizontal side strut.
  • these bottom ribs starting in the middle cannot transfer loads acting on the supports and thus the cover, as they are only connected to the supports via the continuous ribs via the side strut.
  • load transfer from top to bottom practically does not occur via horizontal side struts.
  • gutters In general, gutters have the task of collecting surface water and draining it into the sewer system. The requirements for these products are set out in EN 1433 regulates this. It contains particular specifications regarding load-bearing capacity and tightness.
  • Gutter bodies made of concrete or polymer concrete generally have a high load-bearing capacity, as both concrete and polymer concrete can absorb high compressive forces.
  • the wall thickness of these gutters is usually determined by the manufacturing process.
  • plastic gutter bodies are often made with thicker walls than would be necessary for their later function.
  • the aim is for such a plastic gutter body to have almost the same wall thickness ratios everywhere in order to achieve even mold filling and avoid defects in the end product.
  • the gutter walls are primarily reinforced with stable ribbing so that they cannot be bent inwards. The ribbing also diverts part of the pressure forces acting from above, i.e. essentially orthogonal to the longitudinal axis of the gutter, downwards into the foundation.
  • these ribs are usually designed to run continuously vertically and orthogonally to the longitudinal axis of the channel, as in the EP 0 542 701 A1 and equally in the DE 10 2006 026 243 A1 and the DE 298 08 197 U1 shown.
  • the ribs described in the prior art run from support to support on the outside and cannot solve the problem described.
  • these structural elements are also designed with relatively thick walls.
  • the state of the art also includes hollow chamber structures that provide sufficient stiffening of the channel walls and the necessary load transfer. These are known from the documents EP 1 528 154 A1 , FR 2 791 715 A1 , WO 2009/024255 A1 or WO 2014/037555 A1 known.
  • the present invention is based on the object of creating a drainage channel with a channel body made of plastic, which at the same time requires a reduced use of material, but has a consistently high load-bearing capacity.
  • a drainage channel is provided with a channel body made of plastic, which has two channel walls that flank a channel base on both sides and each form a support for a cover, wherein the channel body has ribs, each of which runs continuously on the outside from a first support along a first channel wall, over the channel base and a second channel wall to a second support, wherein the ribs each form a first side rib that runs from the first support at least in sections vertically up to a first branching point, which branches there into diverging downwardly running first rib legs, which each merge into base ribs that are initially vertical and then lead around the channel base and are brought together again via second rib legs in a second branching point, from which a second side rib runs vertically up to the second support.
  • This branching structure also serves as a buoyancy safeguard when installing the gutter bodies. No structural pockets need to be provided, which would require the costly use of side shifters in tool construction.
  • the invention also provides that the side legs extend downwards from the supports in pairs or in groups towards the branching point.
  • Several side struts preferably run vertically along a first section and then converge at an angle towards the branching point, from where they then diverge again, as described above.
  • an X-shape, a star or the like can also be provided.
  • An additional shape in the centre of the branching point is also conceivable and is included in the term branching point, i.e. that the branching point is designed as a material ring, a triangle or the like, for example.
  • Such a drainage channel can specifically provide that the side ribs form an angle of at least 120° with the associated rib legs. This results in at least the same force being dissipated downwards as to the side, whereas the angle can preferably be 150° and a branching into exactly two rib legs is preferably provided at the branching points. This means that each rib leg forms an angle of 60° with the adjacent rib leg in both directions. A structure in the shape of an inverted Y is created.
  • the drainage channel can be designed so that the side ribs at the branching points branch into more than two rib legs. These do not necessarily have to run in a straight line between the branching points, but can also have other, such as wavy, courses.
  • the wall thickness of the channel walls and the channel base can be at least approximately the same as the wall thickness of the ribs.
  • the same wall thickness is used throughout the workpiece. Since the injection mold is set up to a specific wall thickness in terms of pressure and temperature, it is helpful to avoid different wall thicknesses in the same workpiece. However, a slight increase in the wall thickness is often unavoidable at intersections and branching points as well as at angles.
  • the branching points can be located at least approximately halfway up the channel walls. This means that the branching is provided in an area in which the channel has to withstand the greatest lateral load.
  • the branching structure and its surroundings have a particularly stabilizing effect, similar to that of a honeycomb structure, even if a comparatively thin wall thickness is selected. Below the branching, in the area where the side ribs merge into the bottom ribs, begins the area in which the loads are to be transferred to the foundation, thus allowing a strong load transfer.
  • the adjacent ribs are spaced apart from one another, with the side ribs of adjacent ribs preferably being spaced apart no more than twice as far as the bottom ribs of a rib or adjacent ribs.
  • the ribs are discrete and not connected to one another. There is no provision for the force to be dissipated laterally from one rib to the next, since the preferred direction of force dissipation is downwards, i.e. towards the bottom of the channel.
  • At least one, preferably two, side struts can run transversely to the ribs, in particular above the branching point, with these side struts preferably being less raised above the channel walls than the side ribs.
  • These horizontal side struts are intended to additionally help prevent buckling even in thin-walled designs.
  • a cover can be detachably attached to the support of the channel body, preferably with a frame in between, and fixed with a toggle connected to the channel walls.
  • Such covers provide both visual protection and protection against objects falling into the channel. In extreme cases, the covers can also be moved or lifted out by driving over them with heavy loads, so that fastening them seems sensible.
  • the loads acting on the covers are introduced into the side walls of the drainage channel due to their support on the side supports and are diverted into the foundation via the rib structure.
  • the toggle is attached to the side walls. When installed, it runs across the drainage channel and ensures that the cover can be screwed to one point.
  • the toggle is particularly advantageous for the toggle to be held with two ends in both side walls in a receiving recess, which can be limited on the one hand by a flat stop and on the other hand can be accessed via a feed arch, whereby the feed arches of opposite receiving recesses can be arranged in opposite directions and their arch walls can lie together on a circle around a vertical axis of rotation of the toggle.
  • This allows easy insertion of the toggle, which only has to be held at the height of the receiving recesses between the side walls and is inserted into the receiving recesses by turning the ends. Since the receiving recesses are inserted deep into the side walls, a feed arch is required, which the toggle can move through when screwing in. with its ends and which flows into the drainage channel on the one hand and into the receiving trough on the other.
  • the toggle can also be held in the receiving recesses with a detachable blocking element, which prevents the ends of the toggle from twisting into the feed arch. Since the toggle can unscrew again over time when the cover is driven over the feed arch, such a blocking element is useful in order to prevent this rotation from the outset.
  • the blocking element can be a clamp, preferably held in a clamping seat, which runs across the feed arch.
  • This like the clamping seat itself, can be manufactured inexpensively using simple means and is nevertheless effective.
  • the channel base is assigned connecting means for connection to a connecting adapter, which delimits a floor drain, preferably one that can be opened optionally, and preferably comprises an undercut annular groove in which the peripheral locking means of the connecting adapter can be received in a force-fitting and form-fitting manner.
  • a connecting adapter enables connection to different pipes that run specifically underneath the channel body, and there can also be side connections that allow a pipe or a channel to cross the channel body.
  • Figure 1 shows a drainage channel 1 with a channel body 2 made of plastic, which encloses a channel base 5 between a first channel wall 3 and a second channel wall 4 and thereby forms a trough-shaped channel.
  • this channel body 2 is reinforced and stiffened with a plurality of ribs 8.
  • the individual ribs 8 run without touching each other from a first support 6 on the outside around the channel body 2 to a second support 7, so that a force input to the supports 6 and 7, for example due to a load on a cover 18 mounted on the supports 6 and 7 as in Figure 5 shown, via the ribs 8 into a foundation to be formed below the channel body 2.
  • first side rib 9 which runs straight downwards along the first channel wall 3 into the area of the middle of the wall and there meets the first branching point 11.
  • first branching point 11 in addition to the first side rib 9 coming from above, two first rib legs 13 coming diagonally from below meet so that the shape of a trident star is created.
  • the two first rib legs 13 form an angle of 60°, while the first rib legs 13 each form an angle of 150° with the first side rib 9.
  • the two first rib legs 13 diverge further from the first branching point 13 in a straight line and finally form, mirror-symmetrically to one another on the plane of the first side rib 9, another angle 16 with a width of 150° with the ultimately adjoining base ribs 15.
  • the channel body 2 For the installation of a back support, the channel body 2 has a height line 25 on the first channel wall 3. This supports the user when installing the channel body 2 and also ensures that no more foundation concrete is used than is necessary for a secure hold.
  • the first side rib 9 starts under the first support 6 of the first channel wall 3 and passes over the first branching point 11 into the first rib leg 13. This forms an angle 16 with the bottom rib 15.
  • the bottom rib 15 is thus again parallel to the first side rib 9 and runs under the channel base 5 through to the second channel wall 4.
  • the course is essentially a mirror image of the first channel wall 3, coming from below the rib 8 therefore continues from the bottom rib 15 over an angle 16 into the second rib legs 14, which runs diagonally upwards to the second branching point 12 and there meets a further second rib leg 14 and these together merge into a second side rib 10, which finally contacts the second support 7 from the underside and supports it.
  • the two channel walls 3 and 4 have receiving troughs 21, of which only a section with the feed bend 23 is visible in the first channel wall 3 due to the position of the cross section.
  • Figure 4 shows the second channel wall 4 viewed from the inside of the drainage channel 1, so that the view of the receiving trough 21 is clear.
  • the upper part is provided with covers 18, mostly made of cast iron, occasionally also made of plastic.
  • covers 18 are secured using a toggle 19, which is in Figure 5
  • the toggle 19 can independently turn out sideways due to vibrations and dynamic loads.
  • the toggle can be secured by a simple clamp 24, as shown in Figure 5 is shown.
  • the toggle 19 To insert the toggle 19, it is held between the first channel wall 3 and the second channel wall 4 at the level of the receiving trough 21 and rotated towards it.
  • the ends of the toggle 19 are inserted into feed bends 23, which form the opposite receiving troughs 21 in opposite directions.
  • the opposite feed bends 23 lie on a common circle, so that rotating the toggle 19 causes the toggle 19 to rotate over the feed bends 23 into the receiving troughs 21.
  • a clamp 24 is positioned in a clamp fit next to the positioned toggle 19, so that it can no longer escape into the feed bend 23.
  • the side of the receiving troughs 21 opposite the feed bend each form a straight stop 22, so that the toggle 19 is then fixed.
  • covers 18 can then be fixed with a screw 20, which is turned by the toggle 19.
  • the clamps 24 hold the toggle 19 in position, so that the covers 18 can only be released by loosening the screws 20.
  • the gutter body is designed in such a way that various connection options are easily available. This applies in particular to the 90-degree connection of a gutter section laterally to a side connection 28 of the first gutter wall 3, the option of connecting a connection adapter 27 to the gutter base 5, which is held in position in a form-fitting and force-fitting manner by locking elements. A further connection to a pipework can be made via further side connections 28.
  • a connection between several gutter bodies 2 is made using a known tongue and groove connection, which offers the optional possibility of sealing the gutter joint using additional sealants if required.
  • Injection-molded end walls 26 can also be adapted in these areas. For all accessories, except for the covers that are accessible later, it is important that they are made from pure recycled plastic, which has a positive effect on the ecological balance, along with a number of other aspects such as weight, tightness, corrosion resistance and others.
  • Figure 6 shows in a cross-sectional view the connection of the channel body 2 of the drainage channel 1 with the connection adapter 27.
  • This has an edge which has a wedge-shaped edge contour in cross-section, which in turn can be easily inserted into an annular groove of the channel body 2.
  • a floor drain is provided for this purpose, which interrupts the floor ribs 15 and which is surrounded by the groove mentioned, preferably in the form of a circular or oval annular groove.
  • This is a double edge which is formed all around the floor drain, with one of the double edges in cross-section having a locking means, for example in the form of a step. into which a locking means of the connection adapter 27 can engage and thereby connect the connection adapter to the channel body 2 in a force-fitting and form-fitting manner.
