Definitions

• This invention relates to cladding panels for buildings, and to buildings incorporating cladding panels.
• a cladding panel comprises a metal outer skin, a metal inner skin spaced from said outer skin, side members on all of the edges of the panel, to define an enclosed volume therein, and a fire resistant filler within said volume, at least two opposite edges of the panel being provided with projections for engagement with purlins of a structure on which the panels are to be mounted.
• the invention also resides in the mounting of a plurality of panels as aforesaid inwardly of a portal frame structure in a manner which assists the inner members of the portal frame to resist compressive loads.
• said inner and outer skins are corrugated and are arranged so that the surfaces of the corrugations on the outer skin are substanfcially parallel with those on the inner skin, whereby said enclosed volume has a substantially constant dimension between said skins.
• a portal frame structure a purlin framework secured to said structure inwardly thereof, and a plurality of panels as aforesaid secured to said purlins, inwardly of said portal frame structure.
• Figure 1 is a sectional elevation of a portal frame structure, inwardly of which a plurality of cladding panels are secured,
• Figure 2 is a view on arrow 2 in Figure 1
• Figure 3 is a pictorial view of a purlin framework, in relation to the portal frame structure,
• Figure 4 is a section through the longer edges of a cladding panel
• Figures 5 and 6 are sections, to an enlarged scale, on lines 5-5 and 6 ⁇ 6 in Figure 2,
• Figure 7 is an exploded pictorial view shoving the method of attachment of the purlin framework to the portal frame structure
• Figure 8 shows the method of connecting adjacent ends of cover strips which are shown in Figures 5 and 6.
• a portal frame has a horizontal truss 10 and two vertical support structures 11, 12 which are mounted on the ground by means of respective pivot joints 13, 14.
• a pivot joint 15 interconnects the lower horizontal member 16, 17 of the truss 10, and a flexible linkage 18 interconnects the upper horizontal members of the truss 10.
• the arrangement provides ⁇ modification of a three-pin portal frame in which the lower horizontal members 16, 17 are under compression during both upward and downward loading of the truss 10, but the linkage 18 provides that the upper members of the truss are under tension during upward loading only.
• a building framework comprises a plurality of portal frames 19, as above described, arranged in spaced parallel relationship.
• a plurality of cladding panels 20 is secured to a purlin framework (noti shown in Figures 1 and 2) secured inwardly of the portal frame structure.
• Each of the panels 20 is generally rectangular and has a length such that it can pass, with a small clearance, between two adjacent portal frames 19.
• the panels 20 are mounted on a purlin framework which is rigidly secured to the portal frame structure so as to provide for load transfer between the portal frames and the purlin framework. Resistance to compressive buckling of the lower members 16, 17 of the portal frames is greatly increased by the purlin framework and the panels 20.
• a purlin framework comprises a plurality of parallel box-section purlins 25 having internally threaded projections welded thereto.
• the projections 26 are rigidly secured, by means described hereafter with reference to Figure 7, to internally threaded projections 27 welded to the inner runs of the portal frames 19.
• Angle members 28 are secured to the purlins 25 along their lengths, and further angle members 29 have their ends secured to the purlins 25 to maintain the latter in spaced parallel relationship.
• a U-shaped cover strip 45 is secured, as described hereafter, to the underside of each run of the purlins 25 and retains a layer 46 of mineral fibre insulation.
• FIG 4 sections through opposite long edges of a panel 20 are shown.
• Each of the panels 20 has an outer mild steel skin 30 and an inner mild steel skin 31 . Both of these skins are pre-coated with a finish which is commercially available under the designation FVF2.
• Mild steel edge members 32 of thicker gauge than the skins 30,
• the panel skins 30, 31 are corrugated.
• the corrugations 34 are generally trapezoidal in section and in the present example are, as shown in Figure 2, arranged in three groups of 8 corrugations each. In the outer skin the corrugations extend upwardly of the plane of the remainder of the skin, and in the skin 31 the corrugations are depressed below the surface of the remainder of the skin.
• the corrugations 34 on ⁇ hs skins 30,31 are aligned so that the space between the skins 30, 31 is substantially constant over the whole of the area of the panels 20.
• edge members 35 are secured to the skins 30, 31 along the shorter edges of the panels 20 and in conjunction with the skins 30, 31 and edge members
• two steel channels 40 are secured lengthwise along the outside of each purlin 25 and locate ethylene propylene gaskets 41 each of which has a plurality of ridges on both its sides. Both sides of the channels 40 are provided with steps, and extension 42 of the outer skins 30 of the panels are turned down so as to be able to enter the channels 40 and sealingly engage the gaskets 41.
• a U-shaped external cover strip 44 is in snap engagement with the remaining sides of the channels 40 and also engages the gaskets 41.
• an internal cover strip is provided by a steel channel 45 whose length corresponds to the longer dimension of the panels 20.
• Mineral fibre heat-resistant material 46 is adhesively secured within the strips 45, so that when the strips are in position the material 46 lies between strips 45 and the box section purlins 25.
• the strips 45 have projections 48 which are engageable with snap action in the clips 37 to retain the strips 45 in position between the longer edges of the panels 20.
• the dimensions of the cover strips 45 are such that they lie closely adjacent, or in contact with, the edge members 32, and therby provide a continuity o f insulation between adjacent edges of the panels 20.
• FIG. 6 The joins between the shorter edges of the panels 20 are shown in Figure 6, and are generally similar to that shown in Figure 5.
• channels 50 similar to the channels 4 ⁇ previously described, are mounted on respective ones of the angle members 29.
• the channels 50 carry gaskets 41 identical with those previously described, and extensions of the outer skins 30 of the panels 20 engage the channels 50 with snap action and also sealingly engage the gaskets 4l therein, in a like manner to that previously described with reference to Figure 4.
• An external cover strip 51 generally similar to the cover strip 44 described above but substantially wider, also engages the channels 50 and their gaskets 41.
• Further cover strips 52 identical in section with the strips 43 previously described, but having lengths corresponding to the shorter edges of the panels 20, have mineral fibre insulation layers 53 adhesively secured to them.
• cover strips 52 are pushed up into snap engagement with spring clips 37 on the edge members 35 of the panels 20, to provide a heat resistant barrier between these edges. It will be appreciated that the cover strips 45, 52, which are of relatively thin steel, may be deformed transversely relatively easily by pressure from adjacent edges of - the panels 20 , should the panels expand as a result of heat. The strips 45, 52, and their mineral fibre insulation, thus provide expansion joints at the edges of the panels 20.
• the external cover strips 44,51 engage cruciform elements 60, each of which is located in the region of a projection 27 on a portal frame 19.
• the projections.26 on the purlins 25 have internal threads.
• the projections 27 on the portal frames 19 have internal threads of opposite hand.
• a coupler screw 61 has respective threads for engagement with the projections 26, 27, and a rectangular central portion on which a collar 62 is slidably and non- rotatably mounted. Rotation of the screw 61 by the coll 62 may thus urge flat end faces of the projections 26, 27 into clamping engagement with the flat end faces of the collar 62, to provide for transfer of loads between the portal frame structure and the purlin framework.
• the panels 20 are rigidly secured to the portal frame structure by means of suitably spaced holes 63 therein.
• the resulting assembly 26, 27,62 passes sealingly through the element 60, sealing being effected by grommet 64 ( Figure 6) mounted on the element 60.
• Rebates 65 on the elements 60 permit overlapping between these elements and the cover strips 44, 51, and thereby provide a flush surface for engagement by the gaskets 41.
• the ends of the internal cover strips 45 have steps 70 which are mitred at 71 .
• the steps 70 Adjacent the mitres 71 the steps 70 have inwardly folded tabs 76 which can slidably receive a tongue 72 on a cruciform connector 73.
• the connectors 73 are located inwardly of the structure as a whole, adjacent respective ones of the elements 60 ( Figure 7).
• the connector 73 has a central well 74 within which mineral fibre insulation is secured, to complete the continuity of insulation between the ends of the strips 45.
• electric cables 75 may conveniently be led through the spaces within the cover strips 45, 52, and are protected from heat within the building by the mineral fibre insulation 46.
• the panels 20 co-operate with the internal cover strips 45, 52 to provide fire resistance, and with the external cover strips 44, 51 and the gaskets 41 to provide sealing against weather.
