Description

File 35 061
Louvre Support Means
2456507
This invention relates to support means suitable for mounting solar control louvres.
Solar radiation may account for substantial heat input to a building transmitted 6 through glazing and especially through curtain walling systems provided on all elevations of a building. Glass areas of a building may transmit a significant amount of heat to the building interior in certain circumstances. Excess heat requires removal from the building to maintain a desired internal temperature with consequent higher energy costs and a more adverse environmental impact.
12 To mitigate such problems it is known to provide solar shading by mounting louvre systems to curtain walling structures and it is an object of this invention to provide improved louvre support means facilitate the mounting of louvres for solar control and to improve load distribution on the supporting mullions.
Mullions designed for curtain walling systems exist in various forms. Louvre support 18 means provided by this invention are compatible with at least one known box section mullion of the kind having oppositely directed rib members disposed along the longitudinal edges of the outer surface of the mullion, each rib member being formed with groove for retaining a glazing gasket on the outwardly facing side and having a double-walled flange, disposed centrally between the rib members, the flange projecting outwardly from the outer surface of the mullion in use.
24
References to this form of mullion, which will be further described below, are indicated in this specification by the term 'mullion of the type referred to.'
In this specification the terms 'outer' 'outwardly' and 'inner' and 'inwardly' and analogous terms generally refer to the orientation of an element or surface when in 30 situ in a built structure. The terms 'outer' and 'inner' and analogous terms refer to a direction facing towards the exterior or towards the interior of a building respectively.

In one aspect, this invention comprises a bracket for mounting louvre elements to a 36 mullion having an inner end portion adapted to inter-fittingly receive a flange.
portion projecting outwardly from the mullion, lugs provided on opposed sides the inner end portion; the bracket having a cantilever support arm extending outwardly from the inner end portion whereby in use the inner end portion inter-fittingly receives the flange portion and the opposed lugs are respectively engaged within in retaining grooves disposed along opposed longitudinal edge portions of the outer 42 facing side of the mullion to secure the bracket to the mullion
Preferably the inner end portion of the bracket is bifurcated having two leg members defining between them a parallel sided channel portion disposed and arranged to inter fittingly receive the flange portion on sliding engagement of the hook formations within hook retaining grooves disposed on the outer face of the mullion.
48 Preferably the leg members have opposed parallel portions and diverging free end portions laterally inverted hook formations being disposed at the respective ends of the legs.
Preferably the bifurcated inner end portion of the bracket is adapted to be secured to the mullion flange portion received within it.
54
Pre-formed apertures are preferably provided in the bifurcated inner end portion of the bracket for the receipt of fixing pins intended to pass through aligned apertures provided in the mullion flange.
60 The invention will now be described by way of example only with reference to the accompanying drawings in which:
Figure 1 is a perspective view of a bracket
66 Figure 2 is a perspective exploded view of a bracket and mullion assembly.
Figure 3 is a perspective view of a section of mullion of the type referred to

File 35 061
Figure 4 is a perspective view of the bracket and mullion assembly similar to Figure 2 and fitting for the attachment of solar control louvres to the bracket.

Referring to Figure, 1 an aluminium alloy bracket 10 has an outer cantilever arm portion 22 and bifurcated inner end portion in the form of opposed legs 12 which define a channel of partly uniform cross section defined between parallel portions of the legs, the free end portions of the legs diverging and terminating in lugs 78 constituted by hook formations 16.
Figure 3 shows a section of a extruded curtain wall mullion of the type referred to, presently produced by Sapa Building Systems Limited which consists of an extruded box section 100, the intended outer face of which is formed with elements including: opposed rib formations 102 extending along opposite edges of the outer face of the 84 box section, the rib formations each being provided with an outwardly facing groove 103 for retaining a glazing gasket, and each rib forming the outer wall of a bracket retaining groove 105, constituting a retaining formation, adapted for the sliding receipt and retention of the respective hook formations 16, constituting lugs, provided on the inner end portion of the bracket 10 . This arrangement provides a superior load bearing inter-engagement between the bracket and the mullion A 90 centrally disposed double walled flange 104 projecting from the outer side of the mullion box section 104 is closed at its innermost edge by the outer wall of the mullion 100, the flange walls being bridged by an integral web 106 disposed between the inner and outer distal edges of the flange 104. The uniform parallel sided channel 26 lying between the parallel portions of the legs 12 is dimensioned to inter-fittingly receive a projecting portion of the double walled flange 104 when the hook 96 formations 16 are inter-engaged within the hook retaining formations 105. The close inter engagement of a portion of the flange 104 within the channel defined between legs 12 of the bracket adds lateral stability and strength to the assembly. The outer distal edge of the flange 104 is in the form of an open channel for the retention of fixing means and thermally insulating components along sections between brackets.

File 35 061
102 Referring to Figures 1 and 3 the bracket 10 is inter-engaged with mullion by offering the lower end of the inner end portion of the bracket to the upper end of the mullion 104 and aligning the hook formations 16 with the respective bracket retaining grooves 105. A projecting portion of the flange 104 is co-operatingly received within the parallel sided channel section 26 defined between the legs 12 of the bracket. A bracket may then be slid to a required vertical position along the mullion and where apertures 108 20 in legs 12 align with apertures 22 in flange 104 for the receipt of securing pins.
Figure 2 illustrates the further progression of the bracket assembly sequence following the engagement and fixing of a set of brackets as described above. Thermal break spacer elements 30 are inserted into the outwardly facing distal edge portion of the double walled flange 104, intermediate vertically spaced brackets. Glazing panels 114 not shown are introduced into glazing rebates defined between adjacent mullion flanges such as 104 and associated transoms, not shown. A clamping plate 32 having an aperture for the passage of the cantilever arm is secured to the mullion by fixings secured within the distal edge portion of the flange 104 to retain the edge of a glazing panel in sealing engagement with glazing gasket, not shown, located in the glazing gasket grooves 103 of the mullion. A capping plate covering the clamping plate may 120 be similarly attached. The bracket assembly ready to receive means for attaching solar control louvre blades or elements for other purposes is illustrated in Figure 4.
