Description

"A composite panel"
Introduction
The invention relates to a composite panel comprising an external facing, an internal liner sheet and an insulating core between the external facing and the liner sheet.
In the case of such panels which have an external facing which does not have independent integrity a problem may arise if a weight is applied to a panel on one side of a joint between adjacent panels. This can arise during on-site finishing of the panels. The panel to which the weight is applied can deflect relative to the stationary panel which causes problems in applying a finishing membrane.

* Brief Description of the Drawings
The invention will be more clearly understood from the following description thereof, given by way of example only, with reference to the accompanying drawings, in which:-Fig. I is a perspective view of a panel according to the invention; Fig. 2 is a cross-sectional view of the panel of Fig. 1; Fig. 3 is a cross sectional view of a portion of two adjacent panels according to the invention separated; Fig. 4 is a cross-sectional view of the panels jointed together; Fig. 5 is a cross sectional view of an internal sheet of the panel; and Fig. 6 is a view on A-A in Fig. 5.
Detailed Description of the Drawings
Referring to the drawings, there is illustrated an insulated panel according to the invention comprising a generally flat external facing 2, a profiled internal decking sheet 3, and an insulating core 4 between the external facing 2 and internal sheet 3.
The internal sheet 3 is typically of steel material. The core 4 is of polyurethane or * ** polyisocyanurate foam material which fills the space between the facing 2, and the sheet 3. The panel 1 is generally used for a flat or low pitch (less than 2°) roofing system. However, it is envisaged that the panel could also be used as a floor panel. * I. * S * * S.
:. The outer flat facing 2 may comprise a weather membrane or may have a prebonded weather membrane such as a plastics membrane, for example of polyvinyichloride. In this case the PVC membrane is heat sealed at the panel joint when assembled on site.
The outer facing 2 may alternatively comprise a prebonded bitchumen type membrane to which a further bitchumen type membrane may be applied on site. The outer facing 2 may also not have a prebonded weather membrane. In this case, a weather membrane such as a PVC membrane may be applied on site.
The internal sheet 3 has profiled joint-forming portions for connecting adjacent panels, on assembly as illustrated.
The inner sheet 3 comprises a first overlap portion 31 on one side which extends laterally of the external sheet 2 and is free of insulation. The inner sheet 3 also has a second overlap portion 32 on the opposite side of the panel. On assembly, the first overlap portion 31 of the panel receives the second overlap portion 32 of the adjacent panel.
A side edge of the insulating core at the first overlap portion has a first engagement means 20 and the side edge of the insulating core at the second overlap portion has a second engagement means 21 which is opposite to the first engagement means. In this case the first engagement means is provided by a projecting part 20 and the second engagement means is provided by a recess part 21. The projecting part 20 is of generally complementary mating shape to that of the recess part 21.
The side edge of the insulating core at the first overlap portion 20 has a first overlap portion step 23 which defines the projecting part 20 and the side edge of the insulating core at the second overlap portion has a second overlap portion step 24 which defines * ** the recess part 21. The first overlap portion of the insulating core has two generally parallel offset wedge faces 40A, 40B with the first overlap portion step 23 therebetween. Similarly, the second overlap portion of the insulating core has two * ,., 20 generally parallel offset wedge faces 41 A, 41 B with the second overlap portion step * ** * 24 therebetween. *.a
S
* In use, the projecting part 20 of the first overlap portion of the insulating core of one ** panel engages in the recess part 21 of the second overlap portion of the insulating core of an adjacent panel to form a joint therebetween as illustrated in Figs. 3 and 4.
Because of this interengagement deflection of one panel relative to another at a joint therebetween, for example during membrane overlap welding, is substantially avoided.
At least a portion of the side edges of the insulating core 4 between the joint forming portions of the external sheet and the internal lining sheet has an inclined profile and the inclined profiles of the side edges of the insulating core 4 form oppositely directed wedge faces 40A, 40B, 41A, 41B. A side edge of the insulating core 4 of one panel is matched with the opposite side edge of an adjacent panel 20B, on assembly.
For optimum perfonnance the wedge face 40A, 40B of the insulating core subtend an angle of from 700 to 800, ideally about 750 to the outer facing 2 and the opposite wedge faces 41 A, 41 B subtend a corresponding angle of from 1100 to 1000, ideally about 105° to the outer sheet 2.
The internal decking sheet 3 has a plurality of generally trapezoidal portions. For improved performance the side walls of the trapezoidal portions are stepped at 50.
The bases of the trapezoidal sections also have transversely extending reinforcing ribs 60.
For optimum performance the depth of the trapezoidal portions is at least 90mm, preferably about 110mm. The thickness of the insulating foam between the portion of the internal sheet between the trapezoidal portions and the external sheet is generally at least 50mm and may be at least 70mm. * *. S... S * *SS.
It will be appreciated that, if desired, one or more factory applied and/or site applied * S. s*,. 20 seals may be provided at the joint between adjacent panels. One or both of the side * * edges of the insulating core may be covered with an insulating tape. *.
The invention provides an insulating flat roof panel which facilities a high quality joint *. .: between adjacent panels. The joint ensures a high level of insulation and fire performance but also has a high mechanical strength by virtue of the wedge faces of the insulating core at the joint and the overlap. Because of these features the panel may be used in wider spans than has heretofore been possible. The panels are easily handled and can be built up to achieve a 5 to 6 metre double span.
Thus, the invention provides an insulated flat roof panel with highly efficient installation, insulation, fire performance and mechanical performance.
It will be appreciated that the panels may be provided with opposite side edges or two different panels with a similar profile on both side edges may be provided.
The invention is not limited to the embodiments hereinbefore described which may be varied in construction and detail. * ** * * * * ** **S. * * ***. * S. * * S * S.
