Definitions

  • a roof is made by means of a building element in the form of sheet piling having a narrow weakened central [30] Foreign Application Priority Dam zone transverse to its longitudinal direction, by which Au 16,1969 Netherlands ..12507/69 the panel is hoisted from, and attached to, the ridge beam, the panel thereby being automatically bent to U-S. form a gable roof section by gravity The eross-sec- [5 Int.
  • prefabricated folding panels are made of a different material, e.g. of a steel-wood combination instead of pre-stressed concrete and if a box-shaped panel is chosen, then a considerable lower deadweight is obtained, although the material and manufacturing cost will be very high on the contrary, no appreciable reduction in assembly cost (hoisting and assembly cranes) being possible as a result of the great length of the panels.
  • the object of the invention is to provide a very suitable building element for such a triarticulate system, thereby to avoid the drawbacks inherent in the present state of the art.
  • a building element in the form of a roof spanning sheet which is characterized by a sheet-piling configuration, that is, having a substantially castellated cross-section, the sheet piling ridges of which are substantially continuous in the longitudinal direction of the sheet and are at least partly reduced over a linear area transverse to the longitudinal direction of said ridges in the central area of the longitudinal dimension of the sheet, while at least in said area the continuous portion of the sheet consists of resilient material, the arrangement being such that during hoisting by the thus weakened linear area the sheet portions on opposite sides of said area, through their deadweight, perform a pivoting motion about said area, with deflection of same.
  • the invented building element consisting of a suitable steel construction of sheet piling configuration, it may be sufficient for a dwelling with a span in the depth of 9 m and an approximate frontage width of 6.4 m to use eight straight building elements, each 10 m in length and 0.85 m in width, whose deadweight is approximate l l kg/m.
  • a self-supporting, vapor and water-tight roof of very light construction with elimination of roof trusses, purlins, common rafters and roof boardings.
  • the invention furthermore concerns a method of manufacturing a roof span, characterized in that the roof is made by means of a triarticulate system, both upright legs of the system, from a position originally substantially coextensive, being erected pivotally about the joint of said legs, the leg bases moving towards each other, the starting point being a sheet which in its longitudinal direction substantially continues over both legs and which, like sheet-piling, has a castellated cross-sectional configuration, the erection taking place by hoisting by a linear area extending transversely to the longitudinal direction of the sheet piling ridges, the latter being previously removed over said area, at least in part, use being made, at least in said area, for the material with which the sheet continues of such resilient material that during hoisting the legs are pivoted about the weakened area by gravity.
  • the material with which the roof spanning sheet, in the middle of its longitudinal dimension, continues from one leg to the other is formed integrally with said legs and may be of the same material as that of which the rest of the sheet is made, e.g. steel or plastics, or e.g. a suitable plastics material formed integrally with the (e.g. steel) legs adjoining the central area on either side.
  • the sheet piling ridges may be partly ground away in a narrow zone across the sheet, while leaving intact the corresponding outer ridge portions on one side of the neutral plane, thereby to produce said weakened area.
  • the advantage of this feature is that by this simple manufacture treatment the building element is provided with a hinge between the upwardly slanting, legforming sheet or panel portions to be formed, without separating the latter portions.
  • the grinding is so effected that in the erected position with upwardly slanting legs, a substantially V-shaped space is formed in cross-section over the roof ridge, the hoisting taking place from and up to, a ridge beam or ridge board having a complementarily V-shaped bottom in section, to which the lowermost sheet portions, continuing over the weakening area, are attached.
  • a reinforcement strip adapted to the bent or collapsed form of the sheet at that point, e.g. by means of welding.
  • the building element may be provided with holes in the ridge portion for accommodating or letting through coach screws or other suitable means for connection with the ridge beam or ridge board.
  • the hoisting means e.g. in the form of a thin steel cable with a snap, can reach through the opposite holes, permitting two workmen to install the building element, and attach it fully to the ridge beam and the support anchoring in less than 10 minutes.
  • the building element proposed according to the invention provides already in itself a vapor of watertight roof, when a plurality of said building elements are coupled in overlapping relationship, it is mostly desirable from an aesthetical viewpoint to cover the roof, as e.g. of a dwelling-house, with roof tiles or in suchlike manner.
  • the building elements should also comply with ventilation and insulation requirements.
  • sky lights, lucarnes, and chimney recesses can be applied in or between the building elements according to the invention.
  • the invention also relates to a roof spanning construction made by the method described in the above.
  • FIG. 1 shows schematically a steel building element according to the invention in the simplest embodiment for a symmetric gable roof
  • FIG. 2 shows schematically a preferred assembly method for the building element according to the invention
  • FIG. 3 shows schematically the means for attaching a reinforcement strip to the building element.
  • the steel sheeting material can be chosen, for an economical material use, from wide range of available rigidities.
  • 1 represents, in broken line, the building element in outline, lying on the garret floor, 2 representing the building element in partly hoisted condition, 3 representing a tile lath.
  • the ridge beam 5 is considered to be supported on the side face walls.
  • the assembly takes place as follows:
  • the hoisting cable 4 is put through the appropriate bore, pulled down and secured with the snap in the central bore of the building element.
  • the weight of a complete building element for the above-mentioned dwelling is kg, so that the load on the hoisting cable is 60 kg.
  • the building element can be hoisted by the first workman until it touches the ridge beam. Because the cable aligns the holes in the ridge beam and the building element, the second workman only needs to screw the outer coach screws in the appropriate holes, and then to put the snap out of operation in order to screw in the central coach screw.
  • the first workman has meanwhile put the hoisting cable 4 in the next hole through the ridge beam and pulled it down for the next hoist.
  • Each of the workmen attaches at both ends of the building element the anchoring nuts onto the anchoring bolts, thus completing the first cycle.
  • FIG. 3 a further embodiment is shown in which a reinforcement strip is attached to the building element.
  • Numeral 2 designates the flat panel shown in broken lines in FIG. 2 which, owing to the fact that the ridge portions have been removed over some length in the middle (m in FIG. 2), is locally weakened in such a manner that a hinge is formed about which the two panel halves located on both sides of the middle hinge downwardly when the central area is lifted.
  • Reference numeral 6 designates a reinforcement strip whose cross-sectional shape is adapted to the bent form of the central area of panel 2. Reinforcement strip 6 has apertures 7 so that strip 6 can be secured with bolts to the ridge beam 5. The upwardly inclined side faces 9 of said beam abut in the final position with the terminal edges 10 of the castellations of panel 2.
  • a method of forming a roof span comprising providing a substantially planar roof spanning sheet having substantially continuous longitudinal ridges and a substantially castellated cross-section, said ridges being partly ground away in the longitudinal center of the sheet in a narrow zone along a line transverse to the longitudinal direction of the ridges and in which the corresponding outer ridge portions on one side of the neutral face are left intact,the roof spanning sheet being formed from resilient material at least in the area in the longitudinal center of said sheet where the ridges are partly removed, and hoisting the roof spanning sheet by its longitudinal center such that the planar legs of the sheet pivot about said longitudinal center and form upright legs of said roof span.
