Definitions

  • the present invention relates to a roof panel for placing integrally on supports of a roof supporting construction, wherein the roof panel comprises:
  • Such a roof panel is known from the International patent application WO-A-85/03,540, where the frame is rectangular.
  • the transverse profiles are formed from a Z-profile and a C-profile, which is suitable to hook in the Z-profile in assembling neighboring panels.
  • the longitudinal profiles are formed by Z-profiles to be hooked into each other, where a Z-profile of one of the panels is placed on a carrier and extends below the bottom surface of the roof panels, and where said Z-shaped longitudinal profile of the roof panel, which is to abut in assembly, rests on the Z-shaped longitudinal profile, which is connected to the carrier, of the neighboring roof panel.
  • a roof panel according to the known art has for a disadvantage, that in the configuration of a roof to be assembled from the roof panels according to prior art a wind bracing is necessary to withstand forces acting on the roof panels. Furthermore parts of profiles of the roof to be assembled extend below the bottom surface thereof, especially the Z-shaped transverse profiles, which hinders finish of the roof after assembly thereof. Further the longitudinal profiles rest on the carrier with a part of the longitudinal profiles extending below the bottom surface of the roof panels, where the bottom surface of the roof panels and therefore of the roof to be assembled are arranged there above. As a result thereof strong forces act on these parts of the Z-shaped longitudinal profile extending below the bottom surface of the roof to be assembled, where the entire weight of the roof rests thereupon.
  • the present invention is aimed at providing an improved roof panel, which is distinguished in that the mutually abutting longitudinal profiles of separate roof panels in assembled state comprise respectively a Z-profile and an L-profile, wherein the horizontally oriented leg of the L-profile is located at the top of the roof panel and faces away from the Z-profile, and that the Z-profile has a smaller height than the thickness of the roof panel.
  • a roof panel according to the present invention it is possible to have the bottom surface of the roof panel rest on the carriers and still attachment of the Z-shaped longitudinal profile therein to the carrier is accomplished, without forming a hindrance for the neighboring, in assembly connectable L-shaped longitudinal profiles of the neighboring roof panel. In this manner a more favorable and efficient distribution of forces is achieved and relatively light longitudinal profiles can be employed. Furthermore no parts of the longitudinal profiles extend below the bottom surface of the roof to be assembled, which provides a considerable simplification in relation to finishing the roof.
  • a roof panel according to the present invention includes the measure that mutually abutting transverse profiles of separate roof panels each comprise C-profiles, wherein the legs of the C-profiles are directed away from each other.
  • the mutually abutting, substantially C-profiles can be fixed to each other in simple manner, wherein a desired positioning of the roof panels mutually abutting along the transverse profiles can be maintained.
  • the transverse profiles of roof panels mutually abutting along the transverse profiles comprise respectively a C-profile and a Z-profile, wherein the C-profile must be nested in the Z-profile and wherein an L-profile is further mounted on the Z-profile in order to support thereon the bottom plate of the relevant roof panel.
  • the configuration of the transverse profiles according to the present invention therefore provides roof panels, the transverse profiles of which ensure a higher degree of structural integrity and which are simpler and therefore less expensive to produce, whereby cheaper roof panels are obtained having at least the same degree of strength.
  • At least one additional longitudinal profile which serves as reinforcing rib with a comparatively short distance and therefore greater effectiveness than the reinforcing rib in a roof panel of the prior art which is arranged between the longitudinal profiles of a roof panel.
  • the distance to be spanned by the reinforcing rib in the known roof panel is greater than in the case of a roof panel according to the present invention, so that the structural integrity of a roof panel according to the present invention is notably increased in this embodiment.
  • a roof panel in a third embodiment of the present invention includes the measure that the connecting means comprise tightenable engaging members, such as engaging bolts and nuts co-acting therewith or rivets or pop rivets. It is not necessary herein to weld the profiles, which are normally manufactured from galvanized iron, as in the case of a roof panel according to the prior art, wherein toxic gases and other vapours with an environmental impact are released.
  • a roof panel according to the present invention shown in fig. 1 comprises: a bottom plate in the form of a corrugated sheet 7; transverse profiles in the form of C-profiles 2; a first longitudinal profile in the form of a Z-profile 4; a second longitudinal profile in the form of an L-profile 3; insulation material in the form of insulating plate 6; and a cover plate in the form of woodchip board 9, and a moisture-inhibiting layer 15.
  • the C-profiles 2 are connected to the L-profile 3 and Z-profile 4 such that together with corrugated sheet 7, which also forms the ceiling board, they form a tray-like configuration. Construction hereof is shown schematically in fig. 2 from a perspective other than that of fig. 1.
  • the C-profiles 2 are mutually connected by means of ribs 5 which are arranged parallel to L-profile 3 and Z-profile 4. Ribs 5 are per se C-shaped and therefore display a high degree of stiffness against bending load under the influence of the weight of the roof panel when L-profile 3 and Z-profile 4 rest on a support of a roof-bearing construction.
  • the assembly of C-profiles 2, corrugated sheet 7, L-profile 3 and Z-profile 4 is so strong and rigid that a span of at least 15 metres can be realized with a roof panel according to the present invention.
  • the insulation plate 6 herein comes to rest on corrugated sheet 7 in order to obtain the desired insulating properties of the roof panel.
  • This insulation plate 6 must preferably connect close-fittingly to the assembly of C-profiles 2, L-profile 3 and Z-profile 4 enclosing it, wherein the moisture-inhibiting layer 15 is arranged between insulation plate 6 and corrugated sheet 7.
  • This layer 15 comprises for instance PVC foil or a like material.
  • the cover plate takes the form of woodchip board 9, in contrast to roof panels of the prior art, where use is normally made of for instance chipboard, wherein it is noted that the woodchip board 9 further improves the already enhanced structural integrity of the roof panel according to the invention.
  • Woodchip board also provides better holding for connecting means for mounting of the woodchip board 9 on any of the profiles, such as rivets or nails which are driven in with a pneumatic tool.
  • the woodchip board 9 also provides a very good hold for mechanical mounting of the roof covering 8 thereon.
  • the woodchip board 9 has dimensions corresponding with the dimensions of the assembly of the C-profiles 2, L-profile 3 and Z-profile 4.
  • this woodchip board 9 is shifted parallel to the length direction of the C-profiles 2 and parallel to the length direction of both the L-profile 3 and the Z-profile 4, and mounted to protrude over two edges of the assembly of said profiles.
  • the object here is that the roof panel shown in fig. 1 and 2 with the woodchip board 9 can be shifted in overlapping manner over connecting roof panels in order to mount the connecting roof panels protruding under the woodchip board 9 thereon during construction of the roof.
  • a roof covering 8 such as bitumen or bitumen felt rolls is arranged over the thus formed surface of the roof. This construction will be further described hereinbelow with reference to fig. 3 and 4.
  • the roof covering which can also be formed from rubber or plastic, can be arranged per roof panel during construction thereof. Covers or strips, which are per se known in the art, can be arranged over the seams between mutually abutting panels for sealing thereof.
  • roof panels according to the present invention Shown in fig. 3 and 4 are roof panels according to the present invention which are placed on supports 10 of a roof supporting construction to form together a closed roof.
  • the roof panels according to the present invention have a strength and rigidity such that a span of at least 15 metres is possible between the supports 10 of the roof supporting construction.
  • the longitudinal profiles namely L-profile 3 and Z-profile 4 are placed on supports 10 of the roof supporting construction.
  • the transverse profiles, namely C-profiles 2 bridge the distance between supports 10, wherein the distance between supports 10 determines the length of C-profiles 2.
  • the length of roof panels according to the present invention can be varied in simple manner by using C-profiles 2 corresponding with this length in the roof panels.
  • the following procedure is preferably employed.
  • the roof panels are arranged successively in the direction from top to bottom in both fig. 3 and fig. 4. From top right to bottom left an L-profile connects in each case as second longitudinal profile of a roof panel for placing to a Z-profile as first longitudinal profile of an already placed roof panel.
  • the woodchip board 9 of the roof panel for placing herein falls on the Z-profile 4 of the already placed roof panel.
  • L-profile 3 and the Z-profile 4 are then fixed to each other using hardened steel nails, screws, bolts and nuts, pop rivets or other such fixing means, but not a weld joint which is detrimental to the environment as a result of the release of harmful vapour during the welding of galvanized iron, from which L-profile 3, Z-profile 4 and C-profiles 2 are manufactured.
  • a strip of insulation material in the form of self-adhesive foam profile 11, for instance of the type known as "compriband” is arranged therebetween as sealing strip of flexible material which is clamped between L-profile 3 and Z-profile 4 when these are fixed to each other.
  • the dimensions thereof can amount to about 1.5 x 2-3 cm.
  • the strip of insulation material 11 can comprise for instance a strip of rubber or another heat-insulating and air flow-insulating material.
  • the woodchip boards which extend outside the form defined by the longitudinal profiles and transverse profiles of a roof panel, are fixed to the longitudinal profiles and the transverse profiles of other roof panels which connect onto the relevant roof panel and of which a transverse profile and/or longitudinal profile extends below the relevant woodchip board 9.
  • a length of for instance 1.50 m wide roof-covering is arranged on the panels in the middle by for instance stapling or adhering it to the woodchip board.
  • This middle length with an extra length of ⁇ 10 cm is arranged such that at both ends of the roof panel an overhang is formed which preferably amounts to at least 5 cm.
  • Sealed with hot air or glued to the edges of this middle length are strips of a width such that they protrude ⁇ 5 cm over the edges of the panel such that the roof-covering 5 overhangs the panel 5 cm all round.
  • the panels can also be held in stock for a longer period in the open air without a covering being necessary, since in this manner the panels are each watertight in themselves.
