Description

A gasket f or a glazed roof The present invention relates to a gasket for
a glazed roof and, in particular, to a gasket adapted for use in 5 the valley of a glazed roof.
The valley of a glazed roof is generally defined by a valley rafter and a plurality of jack rafters inclined downwardly to meet the valley rafter on each side.
10 Glazing panels or glazing panel assemblies are supported on the jack rafters in known manner so that they span the gaps between adjacent rafters. The lower edges of the glazing panels are disposed adjacent and substantially parallel to the valley rafter. Typically, 15 the pitch of the jack rafters may vary from 10 to 45 with a consequent variation in the valley angle from structure to structure.
Conventionally, in glazed roof construction a rafter 20 gasket is used in the valley of the glazed roof. Such a rafter gasket is generally of flat formation and, being designed for glazing on top of the rafters, is not particularly suitable for use in the valley. As such, the use of a conventional rafter gasket in a valley 25 situation leads to problems with alignment of the glazing panels in the valley, inadequate gutter drainage in the valley and makes no allowance for the variation in the valley angle from structure to structure. The present invention has been made from a consideration of the disadvantages associated with the use of a conventional rafter gasket in a valley situation and in order to provide an improved gasket
specifically designed for use in the valley or V formation of a glazed roof, thereby overcoming one or more of the above-mentioned disadvantages.
5 According to the invention there is provided a gasket adapted for use in the valley of a glazed roof comprising an elongate channel member of generally v shaped cross section defined by wings, the upper surface of each wing comprising a glazing stop 10 projecting therefrom, the outer edges of such glazing stops being adapted to abut an edge of a glazing panel assembly in use, the gasket being adapted to be used on roof valleys having a variation in valley angle from about lOG to 45 , on either or both sides.
Preferably, the glazing stops are generally in the form of triangular cross section ribs. Preferablyr the outer edges of the glazing stops substantially form a right angle with the upper surface of the wing. Preferably, 20 the inner side of the triangular ribs is sloped at an obtuse angle.
Preferably, the upper surface of each wing further comprises one or more flexible membranes in the form of 25 ribs projecting therefrom. Preferably, such membranes are located adjacent the outer free edges of the wings.
Preferably, the outermost membrane extends further from the upper surface of the wing than the innermost membranes. Preferably, the outermost membranes define 30 the outer edges of the wings.
Preferably, the glazing stops are located inwardly from the flexible membranes. Preferably, the flexible
membranes are adapted to be compressed in use against the bottom face of a glazing panel assembly.
Preferably, a small v groove is provided in the upper 5 surface of each wing to facilitate location of fixing means. Preferably, an elongate notch is provided along the channel where the wings meet. Preferably, the upper surface of each wing further comprises a moisture retention rib projecting therefrom for retention of 10 moisture seepage.
Preferably, the gasket is made from dual hard material.
Preferably, the main body of the gasket from the central axis up to and including the glazing stops is 15 made of 80 to 85 shore hardness material. Preferably, the portions of the wings extending from the glazing stops to the outer free edges, including the flexible membranes, comprise 60 shore hardness material.
Preferably, the gasket is adapted to accommodate 20 glazing assemblies up to 35mm thickness.
The invention will now be described further, by way of example only, with reference to the accompanying drawings, in which: Fig. 1 is a crosssection through a gasket of the invention; and Fig. 2 is a cross-section through a gasket of the 30 invention with installed glazing panels.
Referring to figure 1, a gasket 1 of the invention comprises an elongate channel member of generally v shaped cross section defined by wings 2, 4. The wings
( 2, 4 of the channel member are generally identical and may extend at the same angle from the central axis A of the channel member or may extend at different angles therefrom, according to the pitch of the adjacent side 5 of the roof valley in use.
An elongate notch 3 is provided along the channel where the wings meet to facilitate relative movement of the wings to adapt to the desired valley pitch on each side 10 of the valley and to locate and receive the anchoring screws and the like of the exterior capping bars which secure the glazing assembly.
The upper surface of each wing comprises a glazing stop 15 6 projecting therefrom. The glazing stops 6 are generally in the form of triangular cross section ribs, the outer edges of which substantially form a right angle a with the upper surface of the wing. Such outer edges abut the edge of a glazing panel in use and 20 thereby act as a guide for accurately locating the glazing panels in the valley. The inner side of the triangular ribs is typically sloped at an obtuse angle A, for example 135 , so that the ribs firmly support the glazing panels.
The upper surface of each wing further comprises a plurality, typically three, of flexible membranes 8, 10, 12 in the form of ribs projecting therefrom. The outermost membrane 12 extends further from the upper 30 surface of the wing than the innermost membranes 8, 10.
The membranes are located adjacent the outer free edges of the wings and the outermost membranes 12 define the outer edges of the wings.
( The glazing stops 6 are located inwardly from the flexible membranes, typically on the outer half of the wings. However, it will be appreciated that the glazing stops may be located at any suitable location along the 5 wings to suit the desired application and the size of the glazing panel assemblies with which the gasket is to be used.
A small v groove 14 is provided in the upper surface of 10 each wing 2, 4, typically approximately centrally of the wing, to facilitate location of fixing means, such as copper slate nails or screws or the like, therethrough so that the gasket 1 may be secured in place on the shaped valley formation prior to 15 installation of the glazing panels.
The upper surface of each wing further comprises a vertical rib 15 projecting therefrom. The vertical ribs 15 retain any moisture seepage, as it travels down the 20 valley, away from the anchoring screws, which pierce the gasket at intervals along notch 3. The vertical ribs are located between the v grooves 14 and the central axis A of the gasket.
25 Referring to figure 2, the gasket of the invention is adapted to be used on roof valleys having a variation in the valley angle from about 10 to 45 , on either or both sides. The gasket l, 1' is shown with both wings extending at about 450 and with both wings extending at 30 about 25 for illustration.
A glazing panel assembly 16 is installed on each side of the gasket and the outer edges of the glazing stops 6 abut the inner edges of the glazing panel assemblies
( so that the latter are accurately located in the valley. The flexible membranes 8, 10, 12 are compressed against the bottom face of the glazing panel assemblies when placed in position and act to cushion and seal the 5 assemblies.
Typically, the gasket of the invention is made from dual hard material. The main body from the central axis up to and including the glazing stops is typically made 10 of around 80-85 sure hard material. The portions of the wings from the glazing stops to the outer free edges, including the flexible membranes, are typically about 60 shore.
15 The traditional practice of using a conventional rafter gasket in the valley of a roof and the consequent lack of glazing stops resulted in a lack of uniformity in arranging a roof into a valley section since the installer did not have a parallel line for the abutment 20 of the glazing panels. In contrast, the gasket of the present invention overcomes this problem by providing glazing stops against which the installer can place the glazed units. In addition, the glazing stops avoid slippage of the glazing panels.
In addition, the gasket of the invention has the advantage of providing a proper gutter channel to accommodate any leakage which may occur in the valley assembly. The small v grooves provide retention of the gasket into a shaped formation of timber or other material and allow the gasket to be secured in place prior to the
( installation of the glazing panels by inserting random fixings into these v sections.
The gasket of the invention is adapted for use in 5 valleys having angles ranging from about 10 to 45".
The size of the gasket is typically calculated to suit roof-glazing materials up to 35rrun thickness. The height of the glazing stops and the distance of the outer edge of the glazing stops from the central axis may be 10 chosen to accommodate particular size glazing panel assemblies. For example, a wing width of 60mm, a glazing stop height of 6mm and a glazing stop distance of 42nun from 15 the central axis is generally suitable for glazing panel assemblies of 35mm thickness. The height of the outer membranes 12 may be 5.5mm and the height of the inner membranes 8, 10 may be 4mm.
20 For a wing width of 60mm, the span in use between the outer edges of the wings is typically about 85mm for a configuration with 45" both sides and about llOmm for a configuration with 25 both sides.
25 If the gasket is only for use with 24mm glazing panel assemblies, the wing width may be 55mm, giving an overall width of llOmm, for use on roofs with a 45 valley each side. As the angle reduces, thicker timber or wider valley boards are required.
It will be appreciated that the present invention is not intended to be restricted to the details of the above embodiment, which is described by way of example only.
