Definitions

  • a lens-shaped roof includes a compression ring and a network of two groups of equidistant, practically parallel cables which intersect each other at right angles and are fastened to each other at the points of intersection below the plane of the compression ring, and whose ends are attached to the ring.
  • the rim of a roof shell of arcuate cross section is fastened to the ring while the central roof portion rises above the plane of the ring and is connected to the cable intersections by rigid struts attached to corners of the identical, rectangular panels which main- 1y constitute the shell.
  • This invention relates to roofs having the shape of a lens or of a low dome and being of oval, elliptical, or circular shape in plan View, and particularly to roofs which are supported about their rim only.
  • a roof of the type described should provide good drainage for rain water, yet should be low to reduce construction costs and facilitate the heating of the space covered by the roof. It should also be stable and sufficiently rigid to withstand the bending stresses caused by nonuniform snow and wind loads. It should also exert as little stress as possible on a compression ring by which it is bounded horizontally, and it would be convenient to cover such a roof with identical panels.
  • the roof consists of a membrane or thin outer shell and of supporting cables, it has been necessary heretofore to provide an otherwise unnecessary load in the center of the shell to provide aerodynamic stability, and such roofs have been made to slope downward toward the center, requiring a downspout for rain water to enter the covered space from the lowermost central point of the roof.
  • Other cable supported roofs required several cable systems if their shell was to be made light, and be composed essentially of panels of uniform size and shape.
  • the object of the invention is the provision of a roof of the type described which meets the requirements outlined above, but avoids the shortcomings of the known structures.
  • the invention provides a roof in which the two end portions of each of a plurality of cables are fastened to a compression ring which extends in a substantially horizontal plane. A portion of each cable intermediate the ends is downwardly offset from that plane and the end portions of the cable.
  • the rim portion of a roof shell of arcuate cross section is attached to the ring, and the central portion of the shell is upwardly offset from the plane of the compression ring. Struts are fastened between the several cables and the shell.
  • the cables form at least two groups, and the cables of each group extend in respective parallel, substantially vertical planes, and intersect the cables of another group to which they are fastened at the points of intersection.
  • the lower end portions of the struts are fastened to the cables at the points of intersection.
  • the connected panels which form the roof shell may be 3,410,039 Patented Nov. 12, 1968 substantially identical in size and shape, the upper end portions of the struts being fastened to the corners of the panels.
  • the panels may be rectangular.
  • FIG. 1 is a top plan view of a building provided with a roof of the invention, the roof shell being partly removed;
  • FIG. 2 shows the building of FIG. 1 in elevational section
  • FIG. 3 is a perspective view of the same building prior to completion.
  • FIGS. 4a to 42 illustrate sequential stages of construction of the building in partly diagrammatic elevational section.
  • FIGS. 1 and 2 there is seen a hall of elliptical plan whose roof includes two groups 1, 2 of cables arranged in groups of respective, uniformly spaced, vertical planes which intersect each other at right angles so that the cables form a network having square openings.
  • the outer skin of the roof is formed by an upwardly convex shell 4 consisting of identical square panels.
  • the cables 1, 2 are fastened to each other at the points of intersection which are connected with the corners of the panels by vertical struts 3.
  • the panels are covered on the outside with a watertight, thermally insulated coating not shown in detail in the drawing, and are of lightweight material.
  • the rim of the shell 4 and the ends of the cables 1, 2 are fastened to a compression ring 5 which is supported in a horizontal plane by columns 6 uniformly spaced about the circumference of the roof.
  • a circumferential wall 7 is suspeneded from the ring 5.
  • FIGS. 3 and 4a to 4c The method of erecting the building of FIGS. 1 and 2 is illustrated in FIGS. 3 and 4a to 4c.
  • the ends of the cables 1, Z are first anchored on the ring 5, and are connected to each other at the points of intersection.
  • the cables are mounted slack, and their sag is selected according to the shape of the finished roof and the desired normal tension in the cables.
  • Weights 8 are suspended from the intersections of the cables to simulate an expected snow load on the roof, and weights 9 are provided to simulate the static loading of the cables by the weight of the roof panels 4, including the insulating material, and of the struts 3.
  • the tension in the cables 1, 2 is reduced, but the outer shell is put in tension.
  • the shell therefore, is only under light compressive stress when loaded with snow, or may actually still be under tensile stress.
  • the normal stress in the shell can be selected by suitably choosing the weights 8.
  • each cable having two end portions fastened to said ring, and a portion intermediate said end portions and downwardly offset from said plane, and said end portions,
  • each strut having a lower end portion fastened to one of said cables and an upper end portion fastened to said shell
  • said vertical planes associated with each group being substantially uniformly spaced, said panels being angular and substantially identical in size and shape, and said upper portions of said struts being fastened to the corners of said panels.
