Definitions

  • the present invention relates generally to building structure and in particular, to a structural insulating panel and flat roof structure employing the same.
  • flat or horizontal roofs on commercial and residential buildings have been common in warmer, drier climates where water accumulation as a result of precipitation is not a problem. More recently, flat roofs have become popular in cooler, wetter climates. Unlike sloped roofs, flat roofs have ineffective drainage characteristics making them prone to leakage problems. In wetter climates, to deal with this drainage issue, complex water proofing is typically required in flat roofs. In commercial buildings, drains are sometimes provided in the flat roofs to collect rainwater and melting snow and direct the water off of the roofs.
  • U.S. Patent No. 5,144,782 to Paquette et al. discloses a draining system for water which may collect between the upper and lower membranes of a flat insulated roof. Insulating panels located between the upper and lower membranes are provided at both their upper and lower faces with a network of intersecting grooves. The networks of grooves communicate with each other through passages made through the insulating panels or constituted at the insulating panel joints. The grooves and passages provide drainage channels for any water that has seeped under the upper membrane as a result of perforations in the upper membrane. A lower drain is sealed to and opens above the lower membrane to drain water collected by the drainage channels. Drainage of the water helps to prevent deterioration of the insulating panels and water accumulation which may provoke overload problems.
  • a structural insulating panel for use in a flat roof structure comprising upper and lower structural layers and an intermediate layer between the upper and lower structural layers, the intermediate layer being shaped such that the upper structural layer is sloped relative to a horizontal plane when the structural insulating panel is installed in a flat roof structure.
  • the intermediate layer is shaped such that the upper structural layer is sloped in multiple dimensions relative to the horizontal plane.
  • the upper structural layer may slope generally linearly downwardly in generally orthogonal directions or may curve downwardly in different directions.
  • the intermediate layer is shaped such that the upper structural layer slopes generally linearly downwardly in a single direction.
  • the intermediate layer is sandwiched directly between the upper and lower structural layers.
  • the thicknesses of the upper and lower structural layers are selected to give the structural insulating panel a desired fire rating.
  • Each of the upper and lower structural layers may have a thickness in the range from about 1/8" to about 11 ⁇ 8".
  • the intermediate layer may have a minimum thickness of about 1" and a maximum thickness of about 16".
  • a flat roof structure comprising a plurality of abutting structural insulating panels, each structural insulating panel spanning at least a pair of adjacent rafters of the flat roof structure and defining an upper decking surface on which roofing is applied, the structural insulating panels being configured such that the upper decking surface is non-horizontal thereby to promote drainage.
  • the structural insulating panels in one form are arranged at least one of end-to-end and side-to-side with adjacent structural panels carrying mating formations. Sealant seals seams between the adjacent structural insulating panels.
  • a structural insulating panel comprising an intermediate layer sandwiched between and adhered to first and second structural layers, the intermediate layer varying in thickness such that the first and second structural layers are non-parallel.

  • Figure 13 is an enlarged side elevational view of a portion of adjacent structural insulating panels showing an alternative joint
  • Figure 14 is an enlarged side elevational view of a portion of adjacent structural insulating panels showing yet another joint.
  • the flat roof structure 30 comprises a plurality of abutting structural insulating panels 32 arranged in an array.
  • the array comprises six (6) rows and three (3) columns of panels 32.
  • the 6 x 3 array of panels 32 is shown for illustrative purposes only.
  • the dimensions of the panel array can vary significantly depending on the overall size of the flat roof structure 30 and the dimensions of the individual panels 32 in the array.
  • the longitudinal dimension of each panel 32 is selected so that each structural insulating panel 32 spans at least one pair of adjacent rafters 34.
  • each structural insulating panel 32 will have a lengthwise dimension in the range of from about eight (8) feet to about twenty (20) feet and a widthwise dimension equal to about four (4) feet.
  • Suitable fasteners such as screws or nails are used to secure the structural insulating panels 32 to the rafters 34.
  • the upper surfaces 36 of the structural insulating panels 32 define the decking 38 of the flat roof structure 30 on which roofing (not shown) is applied.
  • the structural insulating panels 32 are configured so that the decking 38 is pitched in multiple dimensions thereby to promote drainage towards the outer peripheral edges of the flat roof structure 30. The pitch in each dimension is typically selected so that it does not exceed 1/12".
  • the structural insulating panels 32 in column C1, rows R1 to R3 and in column C3, rows R1 to R3 are configured so that the flat roof structure 30 slopes linearly downwardly to the right as indicated by arrows 40 and slopes linearly downwardly from its central longitudinal axis 42 towards its peripheral side edge 44 as indicated by arrows 46.
  • the structural insulating panels 32 in column C1, rows R4 to R6 and in column C3, rows R4 to R6 are configured so that the flat roof structure 30 slopes linearly downwardly to the right as indicated by arrows 40 and slopes linearly downwardly from its longitudinal axis 42 towards its peripheral side edge 48 as indicated by arrows 50.
  • the structural insulating panels 32 in column C2, rows R1 to R3 are configured so that the flat roof structure 30 slopes linearly downwardly to the left as indicated by arrow 52 and slopes linearly downwardly from its longitudinal axis 42 towards its peripheral side edge 44 as indicated by arrow 46.
  • the structural insulating panels 32 in column C2, rows R4 to R6 are configured so that the flat roof structure 30 slopes linearly downwardly to the left as indicated by arrow 52 and slopes linearly downwardly from its longitudinal axis 42 towards its peripheral side edge 48 as indicated by arrow 50.
  • structural insulating panel 32 comprises an intermediate layer 60 sandwiched between and bonded to upper and lower structural layers 62 and 64 respectively by suitable adhesive.
  • the intermediate layer 60 is formed of expanded polystyrene (EPS) foam and comprises a core 70 typically having a thickness in the range of from about 1" to about 16", a top skin 72 on the core 70 having a thickness of about 7/16" and a bottom skin 74 on the core 70 having a thickness of about 5/8".
  • the upper and lower structural layers 62 and 64 are formed of a suitable structural material such as for example plywood and have a thickness generally in the range of from about 1/8" to about 11 ⁇ 8". The thicknesses of the upper and lower structural layers 62 and 64 are selected to give the flat roof structure 30 its desired fire rating.
  • the core 70 varies in thickness to give the structural insulating panel 32 its desired pitch.
  • the upper structural layer 62 which overlies the top skin 72 of the intermediate layer 60 conforms to the orientation of the intermediate layer and thus, provides the sloped upper decking surface onto which the roofing is applied.
  • One minor side of the lower structural layer 64 has a groove 80 formed therein and the opposite minor side of the lower structural layer 64 has a tongue 82 formed thereon.
  • the groove 80 is shaped to receive a tongue formed on an adjacent structural insulating panel 32 and the tongue 82 is shaped to be inserted into the groove formed in another adjacent structural insulating panel 32.
  • one major side of the lower structural layer may be provided with a groove and the opposite major side of the lower structural layer may be provided with a tongue.
  • one of the seams 90 between two adjacent structural insulating panels 32 is shown.
  • the tongue 82 on the lower structural layer 64 of one structural insulating panel is received in the groove 80 formed in the lower structural layer 64 of the other structural insulating panel.
  • Adhesive caulking 92 is applied to the tongue 82 and/or groove 80 prior to insertion of the tongue into the groove to secure the lower structural layers of the adjacent structural insulating panels 32 together.
  • a sealant 94 such as for example, a foam seal or sill seal gasket, is used to fill any gaps between the intermediate layers 60 and upper structural layers 62 of the adjacent structural insulating panels at the seam 90.
  • the structural insulating panels 32 of the flat roof structure 30 are configured so that the flat roof structure 30 slopes linearly downward in two different directions.
  • a structural insulating panel configuration can be used in flat roof structures 30 to promote drainage.
  • FIGs 7 to 9 another embodiment of a structural insulating panel for use in a flat roof structure is shown and is generally identified by reference numeral 132. Similar to the structural insulating panel 32, structural insulating panel 132 also comprises an intermediate EPS layer 160 sandwiched between upper and lower structural layers 162 and 164 respectively. In this embodiment, rather than sloping linearly downwardly in two different directions, the core 170 of the intermediate layer 160 has a parabolic shape and thus, curves downwardly from its center in all directions towards the edges of the intermediate layer.
  • Figures 10 to 12 show yet another embodiment of a structural insulating panel 232 for use in a flat roof structure. Similar to the structural insulating panels 32 and 132, structural insulating panel 232 comprises an intermediate EPS layer 260 sandwiched between upper and lower structural layers 262 and 264 respectively. In this embodiment, the core 270 of the intermediate layer 260 slopes linearly downwardly in only one direction.
  • FIG. 13 shows adjacent structural insulating panels 32 interconnected via an overlap joint
  • Figure 14 shows adjacent structural insulting panels interconnected via a butt spline joint.
  • the upper and lower structural layers 62 and 64 are described as being formed of plywood. Those of skill in the art will appreciate that the upper and lower structural layers may be formed of other suitable structural material such as for example OSB, metal sheet, fire resistant board etc. Also, the intermediate layer 60 need not be formed of EPS. Other foam material such as for example urethane foam, polyurethane foam, isocyanurate foam etc. or other suitable non-foam material such as for example honeycomb board may be used.
  • structural insulating panels that provide pitched upper decking surfaces are described and illustrated above, those of skill in the art will appreciate that the structural insulating panels may take on other orientations to promote drainage. Of course, if desired the structural insulating panels can be used on wall structures for structural and/or decorative purposes.
