Definitions

  • This invention relates to decking profiles for composite (concrete and steel) floors
  • Composite flooring utilises profiled steel sheeting which acts as permanent formwork for the concrete slab poured on top.
  • the profiled steel sheeting also combines structurally with the concrete so as to act as positive tensile reinforcement in the cured concrete slab.
  • Composite flooring profiles may be trapezoidal, re-entrant (or dovetail) shaped or a combination of these.
  • a light reinforcing fabric is required which acts as anti-crack mesh and as reinforcement to maintain structural integrity in the slab for a specified period in the case of a fire.
  • the mesh reinforcement has to be placed near the top of the concrete slab, in fact a minimum of 15 mm and a maximum of 45 mm from the top of the slab. Standard practice is to place the mesh on wire stools to the correct dimension, which support the mesh at the right height.
  • this invention consists of a castellated profiled metal sheet, for use in composite concrete/steel floor sections, wherein secondary features are formed in flat-topped areas of the sheet, which features run parallel to the castellations, are upstanding from the flat areas in use and have a maximum open width of 25 mm.
  • the secondary features are of dovetail shape, inverted U-shape or of inverted V-shape in section.
  • the height of the secondary feature is between 13 and 31 mm above the flat area.
  • the secondary features allow a mesh to be supported without the use of stools.
  • the open width maximum of 25 mm is chosen to restrict the upward passage of heat into the concrete slab, in case of fire.
  • the invention consists of a composite concrete/metal floor wherein a profiled metal sheet, as defined above is used to support a mesh which is embedded in concrete.
  • a profiled sheet according to this invention is of generally trapezoidal shape with sloping walls 1 and 2 and a flat top 3.
  • This top is formed with secondary features of dovetail section 4 which runs parallel to the main sheet profile, and is used to support a mesh 5 which acts as a reinforcement when the sheet is used as a decking for a concrete floor.
  • the concrete is poured through the mesh and bonds with the underlying steel profiled sheet.
  • the secondary feature 4 should be not more than 25 mm wide at its open end and should be between 13 and 31 mm in height.
  • secondary features 4 are of different geometrical shapes, although they still serve the same purpose (to support the mesh reinforcement). They can be formed in the flat areas of the sheet by rolling or pressing operations.
