Definitions

  • the present invention relates to metal cover structures for buildings, cantilever roofs, stadiums and so on, and more particularly it concerns a vaulted cover structure made of key-pattern corrugated plate.
  • Cover structures of such kind have already been proposed, and they generally consist of a plurality of arc-shaped elements that are arranged side by side across the depth of the structure to be covered and are secured, at the arc ends, to supports allowing mounting the covering on the structure to be covered.
  • One or more tightening members (known in the art as "tie-rod"), extend(s) along one or more arc chords and is (are) secured at its (their) ends to anchoring means to keep the desired curvature.
  • a vaulted cover structure made of key-pattern corrugated plate having a simple and effective arrangement for securing the tie-rod.
  • the cover structure according to the invention is characterised in that the anchoring means of the tightening members are integral with the lower part of one cover element, externally to the supporting means, at such a position that the intersection between the axis of the tightening member and a cutting line of the element by a vertical plane passing through said axis is located outside the element, at a region where the element leans on the structure to be covered.
  • the anchoring means advantageously consist of a metal section bar, or a foliated wood member or a concrete member.
  • a cover structure comprises one or more arc-shaped or vault-shaped plate elements 1, the number of which depends on the depth required for the cover structure itself.
  • Anchoring members 3 are in turn secured to members 4 supporting the ends of element 1.
  • Supports 4 are associated with members 5 for mounting the cover onto a top curb or knee wall 6 of the structure to be covered.
  • mounting takes place with the hinge-slide system, i.e. one member 5, e.g. the one denoted 5a, is slidable to compensate the steel plate deformation due e.g. to the load, and the other one, denoted 5b, is stationary.
  • the hinge-slide system i.e. one member 5, e.g. the one denoted 5a, is slidable to compensate the steel plate deformation due e.g. to the load, and the other one, denoted 5b, is stationary.
  • both members 5a and 5b may be stationary or slidable.
  • anchoring members 3 of tie-rod 2 are located beneath element 1, externally to the corrugated key-pattern profile thereof, in such a position that, in a vertical plane passing through the axis of tie-rod 2, the intersection between said axis and the arc representing the cutting line of the element is located outside element 1, substantially at the region where the element leans on curb or knee wall 6, as better shown in Fig. 4.
  • anchoring member 3 is a metal section bar, but it can consist of a foliated wood member, a concrete member, etc.
  • Fig. 2 shows in cross-sectional view and in enlarged scale the end portion of a cover module comprising three elements 1a, 1b, 1c arranged side by side across the cover depth, as well as the whole of support 4 and of mounting means 5.
  • Each element 1a, 1b, 1c has for instance a pair of corrugations 10 of the key-pattern profile separated by a dovetail region 11, and ends with two dovetails that are only partly formed, as shown at 11a at 11c for outermost elements 1a, 1c in the module, and serve for the coupling with complementary portions of the dovetail region in an adjacent element.
  • An element of this kind can be manufactured by forming first a flat element by the method disclosed in Italian Patent Application No. MI99A000367 and then bending the flat element.
  • Tie-rod 2 of a module is fastened at the centre of the module; however, in particular cases, a module can be equipped with multiple tie-rods arranged depending on the needs.
  • Brackets with inverted-U profile are introduced inside corrugations 10. Said brackets form in the whole support 4 and are carried by a plate 5 forming the member for mounting the module onto the structure to be covered. Elements 1a, 1b, 1c in the module are secured by bolts to both the upper portions of brackets 4 and plate 5, for instance at both sides of each dovetail region 11.
  • Plate 5 is bent along line 5a (Fig. 3) so as to form an obtuse angle, as better shown in Fig. 4.
  • One side of the angle leans onto curb or knee wall 6 and the other side is secured to the end portion of the arc and is inclined like that end portion.
  • Fig. 4 shows the end portion of a pair of adjacent bays 1' and 1" of the cover structure and relates to the stationary part (hinge) of the cover mount.
  • Figs. 2 to 4 also show the preferred embodiment of anchoring member 3 as a metal section bar.
  • That bar comprises: a vertical flange 30, substantially lying in the plane of the sectional view of Fig. 1 and having a seat 31 where tie-rod 2 is inserted; an upper flange 32, which is inclined like the end portion of arc element 1' or 1" and is to be secured to plate 5, e. g. by means of bolts; and a rear stiffening flange 33, arranged in a plane substantially perpendicular to the plane of flange 32.
  • Such a structure is easy to mount and has the required structural stiffness.
