Definitions

  • This invention is concerned with improvements in or relating to the manufacture of concrete or similar products and is particularly related to the manufacture of drainage blocks.
  • a conventional form of drainage block has a substantially rectangular cross-section with the channel extending longitudinally therethrough, the channel being open onto an upper face of the block through aligned slots extending longitudinally of the block.
  • Such slots are susceptible to the accumulation of dirt etc., and to prevent clogging it is important to periodically clear the slots. This has proved to be a labourious and time consuming operation, mainly because the slot arrangement is not continuous.
  • an insert for a mouldoble drainage member comprising a nair of walls spaced apart by bridging parts, the walls being outwardly divergent relative to one another from one side edge of the insert, and each of the bridging parts having opposed faces outwardly divergent relative to one another in a direction away from said one side edge of the insert.
  • the bridging parts termingte short of said one side edge of the insert may be a fabricated component or produced from a moterigl blank.
  • Aecording to the present invention there is also provided a drgingne nember having a drainage channel extending therethrouga and a slot on one face opening from externqlly into the drqingde channgel olong the length therenf, the slot having walls which are outwardly divergent relative to one another in a direction towards the drainage channel, and o lining defined by an insert as described in either of the two preceding paragraphs.
  • the drainage member is formed with openings extending longitudinally through the material thereof at other than the locations of the drainage channel and the slot.
  • a concrete drainage block has a drainage channel 12 of circular cross-section extending longitudinally therethrough and a slot 14 along an upper face of the block 10 communicates with the channel 12 along the length thereof.
  • the upper and lower faces of the block 10 are parallel, with the lower face having a greater lateral dimension.
  • the upper face slopes downwardly from the outer edge towards the slot 14.
  • the sides of the block 10 are each defined by an inwardly angled section 16 and a vertical section 18 for a purpose hereinafter described.
  • the block 10 can be end pressed by virtue of the provision of the unrestricted slot 14 and can be pressed by a semi-dry process or a conventional wet process.
  • a pair of longitudinal through openings 20 are provided in the block 10 to reduce the weight of the block.
  • An insert 24 defiling a lining for the slot 14 has side wolls 26 connected, for example by welding, with sloping edges of longitudinally spaced welded bridging portions 25 such that the walls 26 ore angled towards one another in an upward direction. Further the walls 26 have upper edge sections 26a turned laterally outwardly to seat in recesses in the upper face of the block 10 at the edges of the slot 14 so as to lie flush with the upper face.
  • the welded bridging portions 25 terminate short of the upper end of the slot 14, and thus the slot 14 is unobstructed along the length of the lining over the distance above the welded bridging portions.
  • the insert 24 is slidable into the slot 14 from an end of the moulded block 10 and can be secured in position by grouting or adhesive.
  • the insert 24 may be cast into the block 10, having additional parts for keying into the concrete.
  • the outwardly flaring side walls 26 of the insert 24 with the complementary flared sides of the slot 14, as well as the outwardly sloping side faces 28 of the bridging portions 25 extending between the side walls of the insert 24, enable the passage into the drainage channel of material which otherwise tends to clog the slot.
  • the insert 24 also provides the block 10 with smooth and accurately formed surfaces over which drainage takes place.
  • the blocks 10 When being positioned on site, ' the blocks 10 are laid end to end on d suitable base support which may extend up to the top of the angled section 16 of the side walls.
  • the blocks 10 are secured to the support by grouting or the like and any suitable elements such as blocks or slabs can then be laid against the vertical sections 18 of the side walls.
  • a slidable insert 24 may overlie the join between adjacent blocks 10 to facilitate connection of the blocks, and also any suitable form of connectors may be positioned through the longitudinal openings 20 to connect adjacent blocks together.
  • the slot 20 can be easily cleaned by any appropriate cleaning tool passed along the slot which is unobstructed above the bridging portions 25.
  • any appropriate cleaning tool passed along the slot which is unobstructed above the bridging portions 25.
  • the bridging portions 25 are angled such that the tool is simply deflected upwardly and not permanently obstructed.
  • With the lining being formed of metal it is also more easily cleaned and the edges of the slot are not susceptible to breakage.
  • the use of the metal insert also reinforces the drainage block.
  • the insert is preferably formed of stainless steel, is easy and inexpensive to manufacture and thus does not significantly increase the cost of production while obtaining the advantages outlined above.
  • the ability to use different pressing techniques enables the longitudinal openings to be formed, thus reducing the weight of the component and facilitating transport etc.
  • the drainage block may have other than the shaped sides as described and may be a block of conventional cross-section.
  • the insert may be made of other than stainless steel and it may have other than the configuration described and shown.
  • the insert may be produced from a material blank which is provided with cuts so as to define portions capable of being subsequently pressed and connected to form the lining having walls spaced apart by bridging parts, and keying parts if desired.
