Abstract
Description
- This invention relates to a rainhead construction, particularly a rainhead which has one or more features to facilitate overflow of water outside of a building even if a section of the rainhead becomes blocked. In a particular aspect, the invention provides compliant overflow while maintaining a traditional rainhead aesthetic by means of the external wall of the rainhead which shields a direct line of sight into the end of the box gutter but which does not impinge the potential for the rainhead to discharge overflow water if the rainhead outlet becomes blocked or if the flow of water is beyond the capacity of the stormwater drainage system to cope with.
- Any discussion of documents, devices, acts or knowledge in this specification is included to explain the context of the invention. It should not be taken as an admission that any of the material forms a part of the prior art base or the common general knowledge in the relevant art in the United States of America, or elsewhere, on or before the priority date of the disclosure herein.
- Australian/New Zealand Standard (“AS/NZS”) 3500.3:2015 (hereinafter simply referred to as “3500.3”) stormwater drainage code (titled Plumbing and
drainage Part 3 Stormwater drainage) specifies three types of overflow devices for box gutters, namely: (a) a rainhead; (b) a sump/side overflow device; and, (c) a sump/high capacity overflow device. - A rainhead operates in such a manner that an increase in the depth of water flow in a box gutter, operating up to its maximum design hydraulic capacity, is not required when the downpipe becomes blocked and the stormwater is required to overflow a wall forming a weir at the front of the rainhead and discharge to atmosphere. Conversely, types (b) and (c) above do require an increase in the depth of flow in the box gutter when the downpipe is blocked, in order for the device to allow overflow to occur up to the maximum design hydraulic capacity of the box gutter.
- This invention relates to the first of the three types of above noted overflow devices, namely (a), and may be an alternative to the rainhead as currently prescribed by 3500.3.
- The proposed invention may operate in a similar manner to the currently prescribed rainhead in that, under normal flow conditions up to the design hydraulic capacity of the box gutter, the stormwater discharges into the downpipe connected to the underside of the rainhead, and from there flows in an unimpeded manner to the legal point of discharge for the property via the underground stormwater drains. However, this invention differs significantly from the currently prescribed rainhead in the following manners:
-
- a) This invention is physically similar to the prescribed rainhead, except that it has an additional external ‘compartment’ at the front of the rainhead, which hides the weir, effectively making this an ‘internal’, non-visible, weir.
- b) When the downpipe is blocked or its flow capacity is exceeded, instead of the stormwater overflowing an ‘external’, visible weir and discharging directly to the atmosphere as drawn in 3500.3, the stormwater firstly overflows the (now) ‘internal’, non-visible weir, and then potentially impacts with the ‘external tub wall’ (outer wall of the additional external compartment), before finally discharging vertically, or near vertically, to atmosphere through the primary overflow outlet at the bottom of the rainhead.
- c) This invention has a secondary overflow provision, being an outlet/opening (typically rectangular, but other shapes, such as circular may be used provided they supply the necessary capacity) located within the front face of the device (the external tub wall), which operates in a similar manner to the overflow for a sump/side overflow device. However, it is considered extremely unlikely that this secondary overflow provision would ever be required, since it would require both the downpipe/internal receptacle and the ‘primary’ overflow provision to both be blocked.
- d) This invention is considered to have a significant aesthetic advantage over the currently 3500.3 prescribed rainhead because the additional compartment at the front of the device effectively hides the box gutter and the weir, albeit other than a small portion of which may be visible through the secondary overflow provision. It is therefore considered to be a substantially visually preferable device, which is significantly more likely to be selected by architects, building designers and plumbers and the like, over the currently prescribed rainhead in 3500.3 (which in itself is not even commercially available).
- This invention is also considered to have substantial advantages over the prior art because visual inspection from below (typically at ground level), and even by a completely untrained person, can quickly and easily confirm if the primary overflow outlet is blocked or clear. The design of the invention ensures that as long as the primary overflow remains visually clear, the invention will continue to work and protect the building from internal flooding. This is unlike currently available rainheads, all of which require access to the rainhead itself (or above it) for inspection purposes. The invention therefore has substantial Occupational Health and Safety benefits in association with routine maintenance and inspections.
- According to one aspect, the invention provides a rainhead comprising: a tub member; an internal receptacle in the tub member having an internal wall forming a weir spaced from an external wall of the tub member; an inlet arranged to direct water flowing from a gutter into the internal receptacle; and, a chute between the internal and external wall, the chute being arranged to receive water overflowing from the internal receptacle to allow it to drain from the chute through a chute outlet.
- Preferably, a downpipe outlet is provided to drain water from the internal receptacle. The preferred downpipe outlet may be omitted where there is a need to allow an installer the option of cutting an outlet hole to fit a particular size of downpipe.
- Preferably and optionally, a secondary overflow outlet may be arranged in the external wall to receive water overflowing from the internal receptacle and chute to overflow out of the rainhead through the external wall.
- Preferably, the top of the internal wall is generally lower than the bottom of the inlet. It is also preferred that it may be sharp edged or rounded.
- Preferably, the bottom edge of the preferred secondary overflow outlet may be arranged so that it lies lower than the top of the internal wall. It is also preferred that it may be about 25 mm lower.
- Preferably, the internal receptacle during normal flow conditions up to the design flow rate and assuming no blockage should be large enough to receive all water flowing through the inlet from a rain gutter without the receptacle overflowing. Generally speaking, this may be achieved by making the cross-sectional area of the inlet and/or gutter directed into the inlet a multiple of the cubic capacity of the receptacle. Preferably, the capacity of the receptacle may be 5 to 45 times the cross-sectional area of the inlet. For example, if the inlet has a cross-sectional area of 1 cm2 , then the receptacle may have a capacity of 5 to 45 cm3. More preferably, the receptacle may have a
capacity 15 to 30 times the inlet area. - Preferably, the inlet may have a cross-sectional area 0.5 to 4 times the cross-sectional area of the chute outlet. More preferably, it may be 1 to 3 times.
- Preferably, the overflow outlet may have a cross-sectional area 0.1 to 1 times the area of the inlet, more preferably 0.15 to 0.5 times the area of the inlet.
- These and other essential or preferred features of the invention will be apparent from the description that now follows.
- In order that the invention may be more clearly understood and put into practical effect there shall now be described in detail preferred constructions of a rainhead made in accordance with the invention. The ensuing description is given by way of non-limitative examples only and is with reference to the accompanying drawings, wherein:
-
FIG. 1 is an isometric view of a rainhead constructed in accordance with a preferred embodiment of the invention viewed from above; -
FIG. 2 is an isometric view of the rainhead ofFIG. 1 taken side on; -
FIG. 3 is an isometric view of the rainhead ofFIG. 1 taken from underneath; -
FIG. 4 is an isometric elevational view of the rainhead ofFIG. 1 ; -
FIGS. 5 and 6 are isometric views of an alternative rainhead construction made in accordance with a further preferred embodiment of the invention; -
FIG. 7 shows the nappe profiles downstream of a box gutter; and -
FIG. 8 shows the nappe profiles downstream of the internal wall. - Referring to
FIGS. 1 to 4 , there is shown a rainhead generally designated 1, comprising atub 3 with aninlet 4 shaped to receive the rain guttering (not shown) from the roof (not shown) of a building (not shown). - The inlet includes a
gutter receptor 5 shaped so that a channel shaped gutter (not shown) may comfortably and even snugly fit therein. - An
internal wall 7 forming an overflow weir is provided in thetub 3. Theinternal wall 7 divides thetub 3 into aninternal receptacle 8 and achute 11 formed between anexternal wall 9 and theinternal wall 7. - Suitably, the
internal wall 7 may be at a level slightly below the level of the bottom edge of theinlet 4. - A
chute 11 has achute outlet 13 which allows water (not shown) to overflow from therainhead 1 should theinternal receptacle 8 become overloaded with water flow or blocked for any reason. - The
internal receptacle 8 is provided with adownpipe outlet 15 to which a conventional downpipe (not shown) may be connected. Thedownpipe outlet 15 may be omitted to allow a user (not shown) to cut out an appropriately sized outlet to accommodate different downpipe dimensions. - As a further precaution, should both the
internal receptacle 8 orchute outlet 13 become blocked, such as, by leaves or twigs or foreign objects (not shown), anoverflow outlet 17 may be formed in theexternal wall 9. Theoverflow outlet 17 may be provided at a level where its bottom edge is below the level of the top of theinternal wall 7, but above the calculated impact point of the free overflow from theinternal wall 7 forming a weir. - A
moulding 19 may be provided around three quarters of the top of thetub 3, both to lend rigidity and to improve the appearance of therainhead 1. - To facilitate attachment of the
rainhead 1 to the side of a building (not shown), an attachment member 21 (as shown, for example, inFIG. 3 ) may optionally be provided in addition to any fixing lugs or the like (not shown). Also, as can be seen more clearly inFIG. 4 , theinternal wall 7 may project slightly below the bottom of theinternal receptacle 8 to prevent water (not shown) falling through thechute outlet 13 from flowing along the bottom of theinternal receptacle 8 onto a wall (not shown) of a building (not shown). - An alternative construction of a
rainhead 1 made in accordance with the invention is shown inFIGS. 5 and 6 . Thealternative rainhead 1 is generally the same as that forFIGS. 1 to 4 , with the exception that amoulding 19A is provided internally of thetub 3. - The
rainheads 1 ofFIGS. 1 to 6 , may be constructed of any suitable material, such as, for example, metal, stainless steel, COLORBOND®, Zincalume Steel®, plastic, aluminium, or copper, etc. - Whilst the illustrated embodiments show box-shaped forms of
rainheads 1, it is to be appreciated that the walls may be curved or bent in any configuration to suit practical needs or aesthetic requirements provided the main features of the invention are present. Thus, the actual shape of therainheads 1 may be box-shaped or may have a different appearance which does not necessarily affect the functionality of therainheads 1. - The relative dimensions of key features of the
rainheads 1 described with reference toFIGS. 1 to 6 of the drawings will preferably be according to those previously defined under the heading “Disclosure of the Invention”. Generally speaking, these dimensions can be chosen to comply with the requirements of Australian Standards. The main requirements of Australian Standards are that a rainhead is physically sealed to a box gutter and has provision to overflow outside a building without restriction in up to a 1:100 year rain event. Therainheads 1 of the invention may be sized to be slightly wider than a box gutter (not shown) that it is servicing to act as a cover plate around broken edges of masonry or render where the box gutter penetrates a building. - The actual sizes of the
rainheads 1 suitable for the particular application and location of use will be determined based on the flow rate for a given roof area having a design rainfall intensity for a 1:100 year reoccurrence period for a specific location in Australia as defined in 3500.3. These areas may be expressed as areas/regions for ease of selection/appropriate application. - The following equations are utilized to compute the nappe profiles downstream of a box gutter, and downstream of the
internal wall 7 respectively. - Downstream of the Box Gutter (Free Overfall)—See
FIG. 7 : -

- While the above description includes preferred embodiments of the invention, it is to be understood that many variations, alterations, modifications and/or additions may be introduced into the constructions and arrangements of parts previously described without departing from the essential features or the spirit or ambit of the invention.
- As the invention may be embodied in several forms without departing from the spirit of the essential characteristics of the invention, it should be understood that the above described embodiments are not to limit the invention unless otherwise specified, but rather should be construed broadly within the spirit and scope of the invention as defined in the attached claims.
