Description
- 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.
- According to the present invention there is provided an insert for a mouldable drainage member, the insert comprising a pair of walls spaced apart by bridging parts, the walls being divergent relative to one another from slot- defining side edges of the insert, and each of the bridging parts having side faces diverging relative to one another in a direction away from said side edges of the insert.
- Preferably the bridging parts terminate short of said side edges of the insert. The insert may be a fabricated component or produced from a material blank.
- According to the present invention there is also provided a drainage member having a drainage channel extending therethrough and a slot on one face opening from externally into the drainage channel along the length thereof, the slot having walls which are divergent relative to one another in a direction towards the drainage channel, and a lining defined by an insert as described in either of the two preceding paragraphs.
- Preferably 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.
- An embodiment of the present invention will now be described by way of example only, with reference to the accompanying drawings, in which:-
- Fig. 1 is a perspective view from one end of a drainage member according to the invention; and
- Fig. 2 is an elevation of the other end.
- Referring to the drawings, a concrete drainage block has a
drainage channel 12 of circular cross-section extending longitudinally therethrough and aslot 14 along an upper face of theblock 10 communicates with thechannel 12 along the length thereof. The upper and lower faces of theblock 10 are parallel, with the lower face having a greater lateral dimension. At each side of theslot 14, the upper face slopes downwardly from the outer edge towards theslot 14. The sides of theblock 10 are each defined by an inwardly angled section 16 avertical section 18 for a purpose hereinafter described. - The
block 10 can be end pressed by virtue of the provision of theunrestricted slot 14 and can be pressed by a semi-dry process or a conventional wet process. A pair of longitudinal throughopenings 20 are provided in theblock 10 to reduce the weight of the block. On one end face there is formed a part-circular groove 22 (Fig. 2) around thechannel 12 and a sealing material can be located in thegroove 22, where-byadjacent blocks 10 can be sealingly joined together around thedrainage channels 12. - An insert 24-defining a lining for the
slot 14 hasside walls 26 connected, for example by welding, with sloping edges of longitudinally spaced weldedbridging portions 25 such that thewalls 26 are angled towards one another in an upward direction. Further thewalls 26 haveupper edge sections 26a turned laterally outwardly to seat in recesses in the upper face of theblock 10 at the edges of theslot 14 so as to lie flush with the upper face. The weldedbridging portions 25 terminate short of the upper end of theslot 14, and thus theslot 14 is unobstructed along the length of the lining over the distance above the welded bridging portions. - In one arrangement, the
insert 24 is slidable into theslot 14 from an end of themoulded block 10 and can be secured in position by grouting or adhesive. As an alternative, theinsert 24 may be cast into theblock 10, having additional parts for keying into the concrete. - The outwardly flaring
side walls 26 of theinsert 24 with the complementary flared sides of theslot 14, as well as the outwardly sloping side faces 28 of thebridging portions 25 extending between the side walls of theinsert 24, enable the passage into the drainage channel of material which otherwise tends to clog the slot. Theinsert 24 also provides theblock 10 with smooth and accurately formed surfaces over which drainage takes place. - When being positioned on site, the
blocks 10 are laid end to end on a suitable base support which may extend up to the top of theangled section 16 of the side walls. Theblocks 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 thevertical sections 18 of the side walls. It is envisaged that aslidable insert 24 may overlie the join betweenadjacent blocks 10 to facilitate connection of the blocks, and also any suitable form of connectors may be positioned through thelongitudinal 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 thebridging portions 25. In the event of a tool engaging thebridging portions 25, the latter 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.
- Various modifications may be made without departing from the invention. For example, it is to be appreciated that 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.
