Definitions

  • This invention relates to flexible sheets for use in the construction of cavity floors.
  • the sheets may be made of another material such as a metal
  • the invention is particularly concerned with flexible sheets of moulded thermoplastics material, and it is in the context of such sheets that the invention will be described.
  • a flexible sheet for use as a support in the construction of a cavity floor, the sheet having a plurality of uniformly spaced legs therein, wherein each leg comprises a plurality of sections, comprising a bottom section, one or more intermediate sections and a top section, each of which is polygonal in horizontal cross-section and has planar lateral faces, the lateral faces of the bottom section of the leg flare upwardly at an angle of less than 60° to the horizontal, and the lateral faces of each of the remaining sections flare upwardly in such a manner that the angle between the lateral faces and the horizontal decreases progressively from the section adjacent the bottom section to the top section of the leg.
  • the horizontal cross-section of the bottom section of the leg is a regular octagon, and the other sections have an irregular octagonal horizontal cross-section and lateral faces consisting of two pairs of opposite identical major faces of the same width and two pairs of opposite identical minor faces of the same width.
  • Such a configuration produces a stronger floor compared with a similar leg design in which all the sections of the leg have a regular octagonal horizontal cross-section because the space between adjacent legs in the region of the top section of the legs is reduced, thus reducing in size zones of potential weakness.
  • the lateral faces of the bottom section of the leg preferably flare upwardly at an angle of 45° to the horizontal and the height of the bottom section is preferably less than about 5 mm in order to prevent electrical or other cables which pass through the cavity from being trapped by the legs.
  • each of the other sections of the leg will vary depending on the overall height of the cavity which it is desired to construct but in each case it is preferred that the height of the bottom section and the height of the section adjacent to the bottom section together are the same as the height of each of the other sections.
  • the material from which the sheet is formed may be another material such as a metal but the material is preferably a thermoplastics material such as polyvinyl chloride, polyethylene, polypropylene or polystyrene.
  • Polyvinyl chloride is the preferred thermoplastics material.
  • the flexible sheet of the invention has the following advantages:-
  • a flexible sheet 1 of thermoplastic material for use as a support in the construction of a cavity floor has a plurality of uniformly spaced legs 2 moulded therein.
  • Each of the legs 2 comprises five sections 3, 4, 5, 6, 7 each of octagonal horizontal cross-section.
  • the bottom section 3 has a regular octagonal horizontal cross-section and lateral faces 8 which flare upwardly at an angle of 45°to the horizontal.
  • the other sections 4, 5, 6, 7 have irregular octagonal horizontal cross-sections and two pairs of opposite identical major lateral faces 9, 10, 11, 12 of the same width and two pairs of opposite identical minor lateral faces 13, 14, 15, and 16 of the same width.
  • the lateral faces 9-16 of sections 4, 5, 6, 7 flare upwardly in such a manner that the angle between lateral faces 9-16 and the horizontal decreases progressively from section 4 through sections 5 and 6 to section 7.
  • Figure 3 shows the shape and configuration of the leg of flexible sheets according to the invention for producing a range of cavity heights from 50 to 130 mm.
  • the height (h) of each of the sections and the length (s5) of the bottom sections are the same.
  • the length (s1, s2, s3, s4) of the other sections varies depending on the overall height of the leg and the height of the cavity to be produced.
  • the height (h) and the lengths (s1 to s5) for the range of legs in the drawing are shown in the table below.
