Definitions

  • WATER DRAINAGE CHANNEL FIELD OF THE INVENTION This invention relates to a water drainage channel and has been devised particularly though not solely as a surface water drainage channel intended to be located in a poured in-situ concrete situation.
  • the present invention therefore provides a surface water drainage channel manufactured from a plastics material and comprising in cross-section a base and upwardly depending side walls having lands at their upper edges adapted to support the edges of an elongate drain grate, characterised by the provision of portions of reduced thickness at the junction of the base and the side walls forming deformable hinges in the plastics material enabling the channel to be manufactured by moulding with the side walls substantially parallel to the base member and then hinged upwardly to form a channel section.
  • the side walls are provided with outwardly protruding elongate flanges extending along the length of the channel .
  • substantially horizontal projections from the side walls may be provided, adapted to prevent a formed channel from floating in a fluid concrete pour.
  • the plastics material is moulded in the area of the deformable hinges to form portions of increased thickness either side of the deformable hinge which are configured to abut one another when the side walls are hinged upwardly to a position substantially perpendicular to the base member .
  • Fig. 1 is a diagrammatic perspective view of a portion of surface water drainage channel according to the invention
  • Fig. 2 is a cross-section to an enlarged scale through the deformable hinge between the base member and side wall of the channel shown in Fig. 1 with the side wall substantially coplanar to the base member
  • Fig. 3 is a diagrammatic cross-section of the surface water drainage channel shown in Fig. 1 in a substantially flat "as moulded" configuration
  • Fig. 4 is a plan view of a section of the channel shown in Fig. 3;
  • Fig. 5 is a side view of the channel shown in Fig. 1;
  • Fig. 6 is a cross-sectional view through the channel showing the use of an assembly handle;
  • Fig. 7 is a scrap perspective view of the end of the assembly handle shown in Fig. 6;
  • Fig. 8 is a scrap view similar to Fig. 2 but showing an alternative form of integrally moulded "living" hinge construction;
  • Fig. 9 is a side view of the assembly handle. DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
  • a drainage channel is moulded from plastics material which may be any suitable material but which is typically a structurally foamed polypropylene.
  • the channel in cross-section, has a substantially planar base member 1 and upwardly depending side walls 2 having lands 3 at the upper edges adapted to support the edges of an elongate drain grate.
  • the lands 3 are typically provided with upwardly extending flanges 4 to locate the grate, the flanges 4 being typically the same depth as the thickness as the grate as can be seen in Fig. 6.
  • the elongate drain grate is typically cast or fabricated from metal such as steel and is typically galvanised before use.
  • the side walls are provided with outwardly extending flanges 5 which will be immersed in the - 4 - concrete so that a portion of the concrete is poured over their upper surfaces .
  • Such flanges keep the channel from floating during a concrete pour and are important in maintaining the upper edges of the grate locating flanges 4 level with the intended surface of the concrete pad during pavement construction.
  • the flanges 5 in Fig. 1 are shown at different heights on either side of the channel, this is for illustrative purposes only to demonstrate that the flange can be lodged in different positions and the flanges in a manufactured channel would typically be at the same height on either side of the channel as shown in Fig. 6.
  • the corners 6 between the base member 1 and the side walls 2 are formed with a reduced thickness so creating deformable hinges in the plastics material . This enables the channel to be moulded with the side walls substantially parallel to the base member, and typically coplanar with the base member, as shown in Fig. 3.
  • Fig. 2 is an enlarged cross-section through the hinge of reduced thickness formed between the side wall 2 and the base member 1.
  • a further version of the hinge 6 is shown in which enlarged surfaces 7 are provided adjacent the integrally moulded "living" hinge 6 and configured so that the surfaces abut when the side wall 2 is bent upwards through 90° to be substantially perpendicular to the base member 1.
  • This hinge configuration enables the drainage channel to be readily formed to the configuration shown in Fig. 1 without the use of jigs or other aligning apparatus.
  • a hinge of this type when folded up into the channel configuration is shown at 10 in Fig. 6.
  • hinges 6 are preferably located at the junction of the side walls 2 and the base 1, it will be appreciated that the same benefit could be obtained by having upturned side edges in the base with the hinge located at the junction of the upturned side edges and the side walls.
  • assembly handles 8 (Figs. 6, 7 and 9) can be provided having elongate ends 9.
  • the side walls 2 of the drainage channel are provided with horizontally extending slots 11 through which the elongate ends 9 may be inserted when in a horizontal configuration and the assembly handle then rotated to the position shown in Figs. 6 and 7 to retain the assembly handle in the position shown in Fig. 6.
  • the handle may be provided with a flange 9A spaced from the elongate end 9 by the thickness of side wall 2, to prevent wet concrete entering through the hole in the side wall when the handle is turned ninety degrees to its locked position.
  • the assembly handle can be moulded from a suitable plastics material and provided with a moulded-in steel nut 8A at its mid-point adapted to receive a bolt to secure the grate to the channel by passing through the channel and into the nut in the handle .
  • the handle is able to form a securing point for the grate 12 (Fig. 6) by the provision of upwardly extending arms 13 having inwardly protruding barbs 14 at their upper ends.
  • the barbs are - 6 - adapted to engage either side of a central rail 15 in the grate 12 in use, to lock the grate securely in position.
  • the assembly handle not only provides a convenient method of handling an assembled channel but also provides a secure location and retention means for the metal grate.
  • the lands 3 may incorporate scalloped out portions in their under surfaces at predetermined intervals to leave sections of reduced thickness at intervals along the length of the channel .
  • concrete can be poured so that it flows into the scalloped out sections to reduce the effect of compression of the structurally foamed plastic when traffic runs over the grate.
  • the scalloped sections are typically 5mm in length every 25mm along the length of the channel and are the total width of the support land 3 underneath the grate .
  • 3 and 4 can be easily adapted by inserting a tool to provide alternative depths of channel enabling different product sizes to be manufactured using the same basic die set.
  • a water drainage channel can be readily manufactured from injection moulded plastics material in an economical manner while providing a superior product that is inexpensive to transport, lightweight and easy to handle on site and able to withstand the loading imposed by heavy traffic.

Abstract

Un canal de drainage d'eaux superficielles est moulé dans une matière plastique. Il présente une base (1) et des parois latérales solidaires s'étendant vers le haut et dotées de paliers (3) destinés à soutenir les bords d'une grille de drainage. Les parois latérales présentent des rebords (5) s'étendant vers l'extérieur, qui empêchent le canal de flotter lorsque du béton est coulé autour de celui-ci. Ledit canal est moulé à l'aide de parties d'épaisseur réduite formant des charnières (6) entre les parois latérales et la base, ce qui permet de mouler le canal à plat dans un moule simple à deux parties, les parois latérales étant repliées à 90° tant que canal n'est pas utilisé.
