Definitions

  • the invention relates to roof structures and has particular reference to their provision in the form of readily assembled prefabricated panels.
  • Embodiments of this invention give short erection times and are low on materials costs. Appearance has often tended to be a secondary consideration where capital investment by purely commercial organisations are concerned. However, and inevitably for the public at large, government agencies place planning permission restrictions. We believe that embodiments of this invention will prove to be satisfactory as to appearance as well as cost.
  • a roof structure made up of prefabricated panels each comprising one pitch of a four-pitch pyramidal assembly on edge-to-edge interconnection, greatly reduces on-site work, especially where, as preferred, such a pyramidal assembly is made up at ground level with an independent structural integrity allowing it to be hoisted complete into position.
  • One particular aspect of this invention thus resides in a preferred panel formation having convergent sides readily interconnected to corresponding sides of other panels, preferably as channel members in base-web abutment thus securable by bolting.
  • Advantageously such channel members comprise parts of a panel edging frame having at least a lower frame member between distal ends of the side members, conveniently also of channel section to permit mounting either by its bottom web or by a lower side web or flange to support posts, pillars or walls.
  • Upper side webs or flanges of such lower frame members preferably make oblique angles with their bottom webs so that roof panel cladding affixed thereto will have a desired pitch angle with those bottom webs vertical. Also, to match with desired pitch angles and the right angle relationship of panels in a four pitch pyramidal roof structure, the upper side flanges of the aforesaid side channel members;will conveniently have an acute inclination to their base webs.
  • the side channel members of at least one, usually all, of our panel frames are interconnected by a further upper framing member, conveniently of hollow rectangular section. Interconnection of such panel frames, side member-to-side member, will then produce a truncated pyramid with a central aperture that may be capped by transparent or translucent material to give natural lighting within a building roofed by one or more such pyramid assemblies.
  • Spigot-and-socket type interconnection of the edging members of each panel frame is preferred for ease of assembly, and is particularly conveniently achieved by means of plates affixed at ends of the or each frame member extending or to extend between side frame members, each such plate carrying an appropriately angled extension to enter those side frame members, usually with a geometrically similar section sized to give a fairly close sliding fit that enhances overall rigidity and strength.
  • Edge-framed panels hereof offer the further advantage that their cladding, usually on upper surfaces .of the framing members, can contribute to overall stiffness, or load-bearing structural integrity, e.g. using corrugated metal panels. That enables the strength required,of the framing member per se to be lower than would otherwise be the case, and roof structures made up therefrom are lighter and more readily handled, and stress is spread through all of their component parts including cladding.
  • Said lower framing members may advantageously have a form, e.g. a stepped bottom channel web, that results in their upper surfaces being inset or rebated from lower parts of those members.
  • Such lower parts are advantageously proud of any overlap of cladding and thus enable interconnection therethrough of adjacent roofing structures.
  • ledges so formed afford a most convenient location for guttering to take away rain water, say using readily available plastics channelling.
  • any channel sections used for panel framing members will usually be of pressed steel plate form and the strengths of such members may be maximised, and their weight for a particular purpose thus minimised, by rolling over and inwardly the free edges of their side webs or flanges.
  • a roof structure made up from panels as aforesaid both before and after lifting onto a structure to be roofed. It should be immediately apparent that preferred rectangular such roof structures can be sized to particular requirements very readily, often using standardised panel lengths. However, and perhaps especially using channel- section lower framing members that may be bolted back-to-back, long buildings can be roofed using a succession of adjacent roofing structures hereof. Large spans can, if desired, be roofed using adjacently disposed roofing structures hereof, either simply bolted together at their lower framing members, or with no more than a post or pillar supporting their adjoining corner or corners.
  • our roofing structures are usuable on posts, pillars or walls as supports therefor.
  • supports in the form of posts usually of reinforcing rectangular hollow section steel, disposed at least at corners.of the roofing structures and preferably equipped with landing cleats or seats on sides of upper ends thereof to take and be secured to bottoms and sides of lower framing members of our panels.
  • Hollow posts offer great advantage as they may accommodate drain pipes from guttering at edges of our panels, which permits entire rain water drainage systems to be of minimum visibility and automatically provides an attractive finish to a building simply clad or bricked in between its support posts.
  • a yet further aspect of this invention comprehends a building system wherein posts are first erected followed oy hoisting onto them a roof structure or structures hereof, which structures may be assembled on-site from our prefabricated panels.
  • Our roof structures may have cladding joints or gaps between adjacent panels at their rising hips flashed over in a particularly simple and convenient manner, even to the extent of permitting the same flashing to serve also ..over triangular capping panels of transparent or translucent materials at the apices of the structures.
  • a roof structure 10 of square pyramidal shape comprises four similar pitches 12 each comprised of a prefabricated panel of truncated isosceles triangular shape surmounted by a triangular apex panel 16 which may be of transparent or translucent material, such as a glass reinforced plastics material, or polyvinyl chloride.
  • Each panel 14 (see Figures 3 to 5) has an edging frame made up of upwardly converging side members 20 and upper and lower frame members 22, 24 between ends of those side members 20.
  • the frame is clad by a corrugated metal sheet 14 secured, typically by bolting, to upper surfaces of the framing members 20 to 24.
  • the frame side members 20 are each of channel section with a bottom web 30 vertical, a lower side flange 32 extending inwardly of the panel and at right angles to the bottom web, and an upper side flange 34 also extending inwardly of the panel but at an acute angle to the bottom web to suit the intended pyramidal instructure.
  • the upper frame members 22 are of hollow square section and the lower frame members 24 are of channel section each with a stepped bottom web 36, 38 essentially vertical, a lower side flange 40 extendinr inwardly of the panel and at right angles to the bottom web, and an upper side flange 42 also extending inwardly of the panel but at an obtuse angle to the bottom web to suit the desired pitch angle.
  • the stepping of the bottom web 36, 38 rebates the upper side flange 42 inwardly by the width of a generally horizontal step or ledge 44 below a short overhang 46 of the cladding sheet 26 for the purpose of affording accommodation of a guttering channel 48.
  • the lower frame member 24 is shown fixed to sheeting 51.
  • the left hand side of Figure 3A shows the bottom web 40 terminating below the upper flange 42 rather than being short thereof as at the right hand side of Figure 3B, to represent preferred options.
  • the channel section framing members 20, 24 are conveniently of pressed steel construction. The ends of their side flanges are all shown turned over towards each other for additional strength.
  • channel sections of the side frame members 20 readily permits adjacent panels to be bolted together through their bottom webs 30, and that the channel sections of the lower frame members 24 eaually readily permits similar bolting together of adjacent roofing structures through their bottom web portions 36, and further allows bolting therethrough to support posts 50, shown as of hollow rectangular section and housing guttering down-spouts 52 that may discharge above ( Figure 8) or below ( Figure 9) ground.
  • An assembled roof structure as being described may be simply set upon walls, typically an inner 64 of a cavity wall ( Figure 6), or.upon reinforcing beams, typically of rectangular hollow steel section 66 ( Figure 7).
  • Hip joints between adajcent roof panels are readily flashed over for weatherproofing as indicated at 72, and the lower parts of the lower channel members are equally readily flashed over the support posts or studs as shown at 74. This can be done on assembly at ground or other convenient working level prior to hoisting into position.
  • the translucent or transparent "sky-light” panels 16 are shown overlapping the cladding sheeting 26 and also the flashing 72.
  • such panels 16 are of similar corrugation to the sheeting 14, and it is equally practicable for the flashing, 72 to be run over the entire hip to the roof apex where the panels 16 meet.
  • panels can be provided with fascia 88 fixed to the gutter 48 and the lower frame member 24.
  • the edging framing and corrugated sheet metal cladding in being secured one to the other make up an integral panel structure that is stressed throughout so that such structural strength as is possessed by the cladding, which is normally very substantial, is fully utilised in the panel itself thereby enabling the use of lower strength and weight edging frame members.
  • roofing panels 14 of this invention may be fabricated either prior to sending out to a building site, or even made up there if desired. Factory prefabrication is,,however, envisaged as the normal mode of practising the invention.
  • the panels 14 will be bolted together to make a pyramidal roofing structure, completed at least with central apex pieces and flashing if not also guttering, and then hoisted into position on a structure to be roofed.
  • FIGS 8 to 13 when using our preferred building construction with hollow vertical posts or studs 50, the latter are first erected by bolting into a concrete platform or base 80 via base plate 82 and then one or more assembled and completed roof structure hoisted and secured in position on post heads 90.
  • the post heads 90 comprise a flange 91, usually welded on, on two, three or four sides of the post 50, the flange being supported by triangular plates 92, and a crown piece 93 having appropriate slots 94 for receiving guttering 48.
  • Figures 10A and B show post head detail for supporting roofing panels at all four corners, Figures 11A and B at three corners, Figures 12A and B at two corners and Figures 13A and B at one corner.
  • the rain water down-spouting will also be a prefabrication with an upper hopper or feed box 84 prefixed thereto. Cladding or bricking in sides of the building may then be done last and protected for weather.
  • edge framed panel parts may be internally skinned as desired, say with thermal insulation 86.
  • the described embodiment provides panels and roof structures having stressed skin characteristics. Also, other than rectangular structures i.e. triangular or polygonal, may be made up from appropriately designed panels.
