Stormwater Outlet

FIELD OF THE INVENTION

These inventions relates generally to the construction industry and particularly, but not exclusively, to a stormwater outlet for connecting stormwater drain pipes from buildings to street kerbs on a road surface or similar carriageways.

BACKGROUND OF THE INVENTION

It should be noted that reference to the prior art herein is not to be taken as an acknowledgement that such prior art constitutes common general knowledge in the art.

Kerbs are constructed in a variety of manners for use with roads, pathways, landscaping, and structures to provide draining options, provide borders for roads, provide support for portions of raised materials, or provide safety or directional means for pedestrians and a variety of transporting vehicles. Typically, kerbs are formed where a raised portion of land or material meets an unraised portion of land or material. A roadway drainage system is formed by a more or less horizontal apron forming the roadway with the kerb extending alongside the roadway and between the roadway and the elevated pavement. The kerb typically extends upwardly from the roadway apron and defines a water pathway between the roadway and the pavement which serves as a path for rainwater to flow to a storm drain. Kerbs are typically constructed of sturdy materials such as concrete, asphalt, stone, or similar materials. Concrete kerbs are popular due to their flexibility for providing a variety of shapes, their relatively reasonable cost, and durability.

Stormwater pipes from a dwelling house or other building, often direct rain water from a roof or from the surrounding yard to the road where they are connected through the kerb or channelling at the side of the road so that water from the house or building is directed by the kerb or channelling into storm water drains. Typically the stormwater pipe terminates at an opening cut into the kerb. Older rectangular kerbs provided a perpendicular surface suitable for boring a cylindrical hole for the drain pipe. However, the contoured concrete kerbs present a surface that is generally difficult to drill into. Consequently, generally known techniques include using a concrete saw blade to remove a rectangular channel in the kerb, after which the stormwater pipe is placed in position and thereafter concrete applied around the end of pipe to provide the neat finish which blends in with the profile of the kerb. The drain pipe extends at least to the edge of the rectangular channel to dispense water. Often the drain pipe is subject to damage from car tires as vehicles driving over the gutter in that area often break down the concrete surround around the end of the pipe and thereby causing damage and possible blockage of the stormwater pipe.

To overcome this disadvantage, there has been proposed an adaptor which is placed within the kerb or channelling and to which the stormwater pipes are connected. The adaptors conform to the profile of the gutter and also provide a neat appearance and finish to the kerb. Typically, these adaptors have been formed from plastics material or cast aluminium and are installed in a similar manner as described above for the stormwater pipe terminating in the kerb. However, they still suffer from damage caused by vehicles driven over the kerb in the region of the adaptor. Damage can be caused to the kerb and to the adaptor through breakage. As a result, the storm water pipe can be exposed and results in further damage and possible blockage of the pipe.

Clearly it would be advantageous if a stormwater outlet could be devised that helped to at least ameliorate some of the shortcomings described above. In particular, it would be beneficial if a stormwater outlet for connecting stormwater drain pipes from buildings to street kerbs on a road surface or similar carriageways was designed or to at least provided a useful alternative.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following description, given by way of example only, is described in order to provide a more precise understanding of the subject matter of a preferred embodiment or embodiments.

Fig. 1 shows a prior art adaptor 10 for connecting a stormwater drain pipe 30 to a kerb or channeling 20 on a side of a road or similar carriageway. The kerb or channeling 20 forms a part of the roadway drainage system and is positioned between the more or less horizontal apron forming the roadway with the kerb 20 extending alongside the roadway and between the roadway and the elevated pavement. The kerb 20 has a first more or less horizontal apron 21 and a portion 22 which typically extends upwardly from the horizontal apron 21 and defines a water pathway therebetween. A further more or less horizontal portion 23 is positioned between the pavement and the portion 22 extending upwardly from the horizontal apron 21.

The adaptor 10 is inserted into a rectangular channel cut into the kerb 20. The cross-sectional shape of the kerb 20 can vary significantly from one housing estate to the next, and even more so, from housing estates in different states of the country. In particular, the portions 22, 23 can vary in inclination and length and also in shape. Therefore, the contoured shape of the top of the adaptor 10 which conforms to the portions 22, 23 of the contoured kerb 20 that are adjacent to the rectangular channel in the kerb 20 will also vary dependent upon the shape of the kerb 20.

The adaptor 10 has a body formed to have a rear surface 13, a bottom surface 11 and lateral side surfaces 12, 16 that are generally planar and parallel to each other, each lateral surface 12, 16, rear surface 13 and bottom surface 11 being generally perpendicular to each other for being placed into a rectangular channel cut into a contoured kerb 20. A contoured top surface 14, 15 largely conforms to portions 22, 23 of the contoured kerb 20 that are adjacent to the rectangular channel. A connector 31 is located on the rear surface 13 for receiving the stormwater pipe 30.

In its broadest form and as illustrated in Figs. 2 and 3, an adaptor 50 is provided for connecting a stormwater drain pipe 30 to a kerb or channeling 20 on a side of a road or similar carriageway. The adaptor 50 has a body formed to have a rear surface 51, a bottom surface 53 and lateral side surfaces 52, 56 that are generally planar and parallel to each other, each lateral surface 52, 56, rear surface 51 and bottom surface 53 being generally perpendicular to each other for being placed into a rectangular channel cut into a contoured kerb 20. A contoured top surface 54, 55 conforms to portions 22, 23 of the contoured kerb 20 that are adjacent to the rectangular channel. At least one reinforcing channel 60 in the contoured top surface 55 is adapted to reinforce a portion of the contoured top surface 55. A bore extends through the body and defines an inlet on one side thereof for accepting an end of the stormwater drain pipe 30 and defining an outlet on an opposite side of said body for exit of the stormwater therefrom.

As noted above the contour of the kerb 20 can vary significantly and therefore the portions 22, 23 can vary in inclination and length and also in shape. Therefore, the contoured shape and length of the top surface 54, 55 which conforms to the portions 22, 23 of the contoured kerb 20 that are adjacent to the rectangular channel in the kerb 20 will also vary dependent upon the shape of the kerb 20. For example, the adaptor 50 in Figs. 2 and 3 is designed for a barrier kerb 20. A barrier kerb has a nearly vertical face which is designed to act as a barrier, preventing vehicles from leaving the road carriageway. The adaptor 50 is placed within a rectangular cut in the vertical face of the kerb 20. The adaptors 70, 80, 90 in Figs. 4 to 6 are designed for semi-mountable kerbs 20. It is noted that there are a number of different styles of kerb 20 and associated adaptors and therefore the invention is not limited to any particular shaped adaptor 50, 70, 80, 90.

The contoured top surface 54, 55 as illustrated does not extend to connect with the bottom surface 53 at the front of the adaptor 50. The portion 54 of the contoured top surface only extends to about half way down the lateral side surfaces 52, 56 which leaves an opening or outlet for the stormwater to expel from the front of the adaptor 50.

The embodiments shown have two reinforcing channels 60 or rectangular tubes 60 which extend from the first lateral side 52 through to the second lateral side 56. However one or more reinforcing channels 60 could be utilised provided the top side portion 55 of the adaptor 50 is reinforced so that in the event that a vehicle drives up and over the kerb 20 damage to the adaptor 50 and the kerb 20 is significantly reduced or avoided.

Each reinforcing element 60 has a substantially square cross-sectional shape and is open at either end 52, 56. However, other cross-sectional shapes could be used without departing from the claimed invention. For example, the cross-sectional shape of the reinforcing element 60 could be rectangular, triangular, circular or in the shape of any type of polygon. The first end 52 of the reinforcing element 60 has an opening 61 and the opposing end 56 has an opening 62. Alternatively, the reinforcing elements 60 may be a solid tube with no openings. The reinforcing elements 60 are designed to reinforce the top side portion 55 of the adaptor 50 so that in the event that a vehicle drives up and over the kerb 20 damage to the adaptor 50 and the kerb 20 is significantly reduced or avoided.

The body of the adaptor 50 is manufactured from steel or aluminium and is preferably with an anti-corrosive coating or powder coated aluminium. Alternatively, the adaptor can be formed from a plastics material. Likewise, the reinforcing elements 60 are also steel with an anti-corrosive coating. Alternatively, the reinforcing elements could be formed from aluminium, powder coated aluminium or a plastics material or any other suitable metal which provides suitable reinforcement for the adaptor 50 which in the event that a vehicle drives up and over the kerb 20 damage to the adaptor 50 and the kerb 20 is significantly reduced or avoided.

As shown in Fig. 3, the adaptor 50 also has a fold-down lock tab 57 located in each lateral side 52, 56. The fold-down lock tabs 57 are designed to anchor the adaptor 50 within the rectangular channel cut into the contoured kerb 20. When the adaptor 50 is inserted into the rectangular channel cut into the contoured kerb 20 the tabs 57 are folded down to resist movement of the adaptor 50 prior to being permanently concreted into the kerb 20. In order to connect the adaptor 50 to the stormwater pipe 30 a connector 31 is inserted into an aperture located in the rear surface 51. Typically the aperture is rectangular in shape to receive the corresponding rectangular insert of the connector 31. By way of example only, a slight recessed peripheral edge extends around the perimeter and forms the inserting portion of the rectangular insert. A rectangular flange portion extending from the inserting portion of the connector 31 abuts against the rear surface 51 of the adaptor 50. The inserting portion forms a press fit connection with the aperture in the rear surface 51 of the adaptor 50. The connector 31 is a PVC plastics material or the like. An adhesive sealant may be added to seal the connector 31 to the rear surface 51 of the adaptor. Alternatively, the aperture and the inserting portion may be any shape provided they correspond. For example, the aperture in the rear surface 51 may be circular to receive a corresponding circular inserting portion.

A pipe connector or spigot extends from the connector 31 which allows the stormwater pipe 30 to be connected to the connector 31. Typically the connector or spigot is circular in cross-section for receiving a corresponding shaped stormwater pipe 30. Alternatively, the connector may be any other shape which corresponds to the cross-sectional shape of the stormwater pipe is 30. The stormwater pipe 30 is retained on the spigot by any suitable fastening device such as a hose clamp or the like. Adhesive may also be applied between the pipe 30 and the spigot to aid in the retention of the pipe 30 to the connector 31.

With adaptor 50 inserted into the kerb 20 and the stormwater pipe 30 connected a drainage system is complete. A bore extending through the adaptor 50 from the inlet at the rear surface 51 to the outlet at the open front section allows the flow of stormwater from the dwelling or other building to the kerb 20 at the side of the road and into the stormwater drains. The opening left between the front top surface 54 and the bottom surface 53 allows the stormwater from the stormwater pipe 30 to exit the adaptor 50 and flow into the stormwater drain on the roadside.

As previously discussed Figs 4 to 6 show adaptors 70, 80, 90 used in semi-mountable kerbs 20. The main difference between each of these adaptors is the shape of the side lateral surfaces and the contoured top surfaces. Given that each of these adaptors are designed to be inserted into a semi-mountable kerb 20, the physical size or length of the adaptor is considerably larger than the adaptor 50 designed for a barrier kerb 20. All of the adaptors 50, 70, 80, 90 are designed to be inserted into a rectangular cut slot in the respective kerbs 20. Likewise each adaptor 50, 70, 80, 90 is adapted to connect to the stormwater pipe 30 through a connector 31 mounted into the rear surface of each adaptor.

Fig. 4 shows the adaptor 70 has a body formed to have a rear surface 71, a bottom surface 73 and lateral side surfaces 72, 76 that are generally planar and parallel to each other, each lateral surface 72, 76, rear surface 71 and bottom surface 73 being generally perpendicular to each other for being placed into a rectangular channel cut into a semi-mountable contoured kerb (not shown). A contoured top surface 74, 75 conforms to portions of the semi mountable contoured kerb that are adjacent to the rectangular channel. At least one reinforcing channel 60 in the contoured top surface 75 is adapted to reinforce a portion of the contoured top surface 75. A bore extends through the body and defines an inlet on one side thereof for accepting an end of the stormwater drain pipe 30 and defining an outlet on an opposite side of said body for exit of the stormwater therefrom. As shown in Fig. 4, the adaptor 70 also has a fold-down lock tab 77 located in each lateral side 72, 76.

Fig. 5 shows the adaptor 80 has a body formed to have a rear surface 81, a bottom surface 83 and lateral side surfaces 82, 86 that are generally planar and parallel to each other, each lateral surface 82, 86, rear surface 81 and bottom surface 83 being generally perpendicular to each other for being placed into a rectangular channel cut into a semi-mountable contoured kerb (not shown). A contoured top surface 84, 85 conforms to portions of the semi mountable contoured kerb that are adjacent to the rectangular channel. At least one reinforcing channel 60 in the contoured top surface 85 is adapted to reinforce a portion of the contoured top surface 85. A bore extends through the body and defines an inlet on one side thereof for accepting an end of the stormwater drain pipe 30 and defining an outlet on an opposite side of said body for exit of the stormwater therefrom. As shown in Fig. 5, the adaptor 80 also has a fold-down lock tab 87 located in each lateral side 82, 86.

Fig. 6 shows the adaptor 90 has a body formed to have a rear surface 91, a bottom surface 93 and lateral side surfaces 92, 96 that are generally planar and parallel to each other, each lateral surface 92, 96, rear surface 91 and bottom surface 93 being generally perpendicular to each other for being placed into a rectangular channel cut into a semi-mountable contoured kerb (not shown). A contoured top surface 94, 95 conforms to portions of the semi mountable contoured kerb that are adjacent to the rectangular channel. At least one reinforcing channel 60 in the contoured top surface 95 is adapted to reinforce a portion of the contoured top surface 95. A bore extends through the body and defines an inlet on one side thereof for accepting an end of the stormwater drain pipe 30 and defining an outlet on an opposite side of said body for exit of the stormwater therefrom. As shown in Fig. 6, the adaptor 90 also has a fold-down lock tab 97 located in each lateral side 92, 96.

The adaptor 50, 70, 80, 90 can be formed by bending and welding a cut sheet of steel or aluminium to form the shape of the adaptor required for the particular shaped kerb 20. Alternatively, a steel, aluminium or plastics material may be moulded, cast or extruded to form the adaptor 50, 70, 80, 90. The steel is a heavy gauge steel with an anti-corrosive coating and the aluminium is powder coated.

The adaptor 50, 70, 80, 90 is utilised to form a drainage path between a stormwater drain pipe 30 and a kerb 20 or channeling on a side of a road or similar carriageway. A rectangular channel is cut in a contoured concrete kerb 20 along a street to expose an end of the stormwater drain pipe 30. The adaptor is inserted into the channel and the connector 31 is attached to the stormwater drain pipe 30. The fold-down tabs 57, 77, 87, 97 are folded down to hold the adaptor in position. The adaptor is then concreted into the rectangular channel to reform the concrete kerb 20.

ADVANTAGES

The present invention provides a stormwater outlet for connecting stormwater drain pipes from buildings to street kerbs on a road surface or similar carriageways. The adaptor has a reinforced top contoured surface which in the event that a vehicle was to drive over that portion of the kerb containing the adaptor the reinforced section would prevent or at least avoid damage to both the adaptor and kerb.

The adaptors are designed to be inserted into a rectangular cut in a contoured kerb. The use of fold-down lock tabs ensures that the adaptor is secured within the cut kerb prior to the concrete being poured to permanently secure the adaptor to the kerb.

The adaptor has a connector located in the rear surface to facilitate the easy connection of the adaptor to the stormwater pipe. The connector is inserted into the rear surface of the adaptor and secured therein.
