  • This invention relates to a floor structure in or for a portable building unit.
  • EP-B-0,058,354, EP-B-0,105,406 and GB-B-2,084,213 each disclose an example of a portable building unit which is factory assembled for delivery to a prepared site in assembled condition.
  • EP-B-0,039,592 discloses an example of a building unit which is intended to be transported in a pack for erection when delivered to a suitable site.
  • the building units of the above mentioned examples have a floor structure which comprises a floor frame comprising a pair of side beams connected together by transversely extending joists and a floor panel supported on the floor frame with an underdrawing of bitumen impregnated fibreboard thermal insulation laid between and supported by the joists with mineral fibre insulation laid between the joists between the floor panel and the underdrawing.
  • a further building panel for use in, for example, ceilings is known from DE-A-3711141, in which the panel comprises a plurality of joists. The panel is assembled on site.
  • Floor panels are provided attached to the upper surface of the joists and plasterboard is attached to battens on the underside of the joists. Resistance to shear forces is provided by screws attaching the floor panels to the joists, wherein the screws have a large diameter shank.
  • Insulation material is provided to partly fill the space between the floor panel and the plasterboard.

  • the floor panel and the underdrawing sheet are made of gas impermeable, or at least substantially gas impermeable, material any gas which permeates outwardly from the expanded plastics material is trapped by the floor panel, underdrawing sheet and the side beams and joists and so is retained within the floor structure, thereby contributing to the thermally insulating properties of the floor panel.
  • the floor panel may comprise a plurality of floor panel elements disposed in side by side relationship.
  • the underdrawing may comprise a plurality of underdrawing sheets.
  • adjacent edge portions of adjacent sheets may be disposed in overlapping relationship, and in particular in the region of the above mentioned recesses.
