Definitions

  • the present invention relates to a modular panel for laying out on a roof to alter the slope of the roof surface.
  • Buildings with flat roofs have the problem that water can accumulate on the surface of the roof when it rains, if the roof has not been designed with a slope towards a drain. This can be particularly noticeable with, for example, large commercial buildings which may have, for example, concrete roofs or steel plate roofs, as these buildings have a large roof surface area. Therefore, such concrete roofs or steel plate roofs are often covered with panels creating a slope in a predetermined direction when laid out on the flat roof. These panels may be, for example, a roof insulation made of foamed plastics, such as expanded polystyrene, on top of which roof felting or another type of roofing material is laid out. Typically, this is carried out by laying out wedge-cut roof insulation panels, optionally combined with support panels, in such a way as give the roof a sawtooth profile or a triangular profile in the longitudinal or transverse direction of the roof surface.
  • valley gutter wedges or counter-slope wedges altering the slope of the roof in both longitudinal and transverse directions are placed on top of the wedge-cut roof insulation panels.
  • valley gutters are formed providing a separate slope towards a drain situated in the middle of the roof.
  • valley gutter wedges have to be cut out with the help of a saw or a heated wire to fit the roof in question where they are to be laid out, which is a resource-intensive process.
  • the different panels cut to size for valley gutters are often comparatively small in size so that they can be frequently blown off the roof after having been laid out because of the low density and form of polystyrene.
  • a new panel is used instead so that a great number of roof insulation panels having been blown off are frequently wasted when laying out a roof.
  • the object of the present invention is to simplify handling of roof insulation panels, to reduce waste thereof when laying them out as well as to reduce production costs.
  • a modular panel for laying out on a roof to alter the slope of the roof surface, where the panel has one or more rupture lines along which the panel can be separated into individual roof panel modules, and where the individual roof panel modules are of varying thickness to alter the inclination of the roof surface.
  • a modular panel may be manufactured, for example by casting, where the panel includes several roof panel modules for positioning in different places on the flat roof. Moreover, it is possible to wait with separating the individual roof panel modules until immediately prior to laying them out, thereby reducing the risk of them being blown off the roof.
  • the panel has at least one first and one second roof panel module, where the roof panel modules may be either a triangular roof panel module or a rectangular roof panel module.
  • the roof panel modules may be either a triangular roof panel module or a rectangular roof panel module.
  • This allows for three simple rectangular modular panels consisting of either two triangular roof panel modules, one triangular roof panel module and a trapezoidal roof panel module or two rectangular roof panel modules.
  • This also allows for a trapezoidal modular panel consisting of a triangular roof panel module and a rectangular roof panel module.
  • the first roof panel module is provided with an end face of substantially the same shape as an end face on the second roof panel module.
  • the two roof panel modules may be separated and laid out in direct extension of one another in such a way that the two end faces fit with each other and that no discontinuity arises between the panels.
  • the panel has at least a first roof panel module in the shape of a right-angle triangle comprising an end face along a comparatively short leg in the transverse direction and a side face along a comparatively long leg in the longitudinal direction, and an abutting rectangular roof panel module comprising two end faces and a side face, said side face having substantially the same shape as and abutting the side face of the triangular roof panel module, and where the end face of the triangular roof panel module has substantially the same shape as one end face of the rectangular roof panel module, preferably the end face facing the opposite direction of the end face of the triangular roof panel module.
  • the triangular roof panel module and the rectangular roof panel module can be separated and laid out in direct extension of one another in such a way that the two end faces fit with each other and thus do not yield any discontinuity.
  • the two roof panel modules may be laid out without separating them, in which case there again is no discontinuity, since the abutting side faces have substantially the same shape.
  • the panel has two or more, preferably three, consecutive rectangular roof panel modules, where the abutting side faces have substantially the same shape, and where one end face of a first rectangular roof panel module has substantially the same shape as the end face of an abutting rectangular roof panel module facing the opposite direction.
  • a first rectangular roof panel module has substantially the same shape as the end face of an abutting rectangular roof panel module facing the opposite direction.
  • the panel additionally has a further triangular roof panel module in the shape of a right-angle triangle, preferably positioned so that its hypotenuse faces the hypotenuse of the first triangular roof panel module, and preferably substantially identical to the first triangular roof panel module.
  • the second triangular roof panel module can be separated from the modular panel and used as the "acute part" of a valley gutter wedge.
  • the rupture lines are provided as a perforation of the panel or as a groove or a recess in the panel.
  • the individual roof panel modules may be separated from each other in a simple manner, for example, by breaking them off from each other along the rupture lines or by cutting the remaining part of the panel with a hobby knife in the groove.
  • the panel is made of an insulating material, for example, foamed plastics, such as expanded polystyrene.
  • foamed plastics such as expanded polystyrene.
  • the panel may be manufactured in a particularly simple manner, and the roof panel modules may be used as roof insulation.
  • Fig. 1 shows a modular panel 1 according to the invention.
  • the modular panel 1 consists of five different roof panel modules W1-W5, preferably made from foamed plastics, such as expanded polystyrene, said modules being separatable along rupture lines 2.
  • the rupture lines 2 may, for example, be perforated lines or a groove marked or cut between the roof panel modules.
  • each roof panel module can be separated from the panel 1 by either breaking it off the panel 1 or, for example, by guiding a hobby knife through the grooves and cutting each roof panel module off the panel 1.
  • the panel 1 has three rectangular roof panel modules W2-W4 and two right-angle triangular roof panel modules W1, W5.
  • the first roof panel module W1 has the shape of a right-angle triangle and comprises a side face 10 along a comparatively long leg and an end face 3 along a comparatively short leg.
  • a second roof panel module W2 which is rectangular is positioned adjacent the first roof panel module W1.
  • the second roof panel module W2 has a first side face 11 and a second side face 12 as well as a first end face 4 and a second end face 5.
  • the first roof panel module W1 and the second roof panel module W2 are connected by means of the side face 10 of the first roof panel module W1 and the first side face 11 of the second roof panel module W2 along a rupture line 2.
  • the side faces 10 and 11 have the same shape.
  • the end face 3 of the first roof panel module W1 has the same shape as the first end face 4 of the second roof panel module W2, which means that the two roof panel modules W1, W2 may be separated and positioned in direct extension of one another without there arising any discontinuity between the roof panel modules W1, W2.
  • a third roof panel module W3 which is rectangular is positioned adjacent the second roof panel module W2.
  • the third roof panel module W3 has a first side face 13 and a second side face 14 as well as a first end face 6 and a second end face 7.
  • the second roof panel module W2 and the third roof panel module W3 are connected by means of the second side face 12 of the second roof panel module W2 and the first side face 13 of the third roof panel module W3 along a rupture line 2.
  • the side faces 12 and 13 have the same shape.
  • the second end face 5 of the second roof panel module W2 has the same shape as the first end face 6 of the third roof panel module W3, which means that the two roof panel modules W2, W3 may be separated and positioned in direct extension of one another without there arising any discontinuity between the roof panel modules W2, W3.
  • a fourth roof panel module W4 which is rectangular is positioned adjacent the third roof panel module W3.
  • the fourth roof panel module W4 has a first side face 15 and a second side face 16 as well as a first end face 8 and a second end face 9.
  • the third roof panel module W3 and the fourth roof panel module W4 are connected by means of the second side face 14 of the third roof panel module W3 and the first side face 15 of the fourth roof panel module W4 along a rupture line 2.
  • the side faces 14 and 15 have the same shape.
  • the second end face 7 of the third roof panel module W3 has the same shape as the first end face 8 of the fourth roof panel module W4, which means that the two roof panel modules W3, W4 may be separated and positioned in direct extension with one another without there arising any discontinuity between the roof panel modules W3, W4.
  • a fifth roof panel module W5 having the shape of a right-angle triangle is connected to the first roof panel module W1 by means of their hypotenuses along a rupture line 2.
  • the short legs of the triangular roof panel modules W1, W5 and the short sides of the three rectangular roof panel modules W2-W4 have a length of, for example, 300 mm
  • the long legs of the triangular roof panel modules W1, W5 and the long sides of the three rectangular roof panel modules W2-W4 have a length of, for example, 1200 mm.
  • the resulting modular panel 1 is square having a side length of 1200 mm.
  • the modular panels 1 may be used to construct a valley gutter wedge 20 of any length.
  • Fig. 2 shows an example, where the panels 1 have been used to make a valley gutter wedge having the length of six panel lengths (7200 mm).
  • the valley gutter wedge is constructed from six rows of roof panel modules in longitudinal direction, where the first row consists of one roof panel module, the second row of two roof panel modules etc.
  • the fifth row consists of the four first roof panel modules W1-W4 of a fourth modular panel and the fourth roof panel module W4 of the second modular panel.
  • the fourth roof panel module W4 of the second modular panel is positioned on top of a support panel C having a thickness of, for example, 20 mm.
  • a valley gutter wedge of any length may be constructed, thus eliminating the need of making parts cut out by means of sawing or a heated wire.
  • a slope towards a drain is to be created on a flat roof, such as a steel plate roof or a concrete roof
  • this is carried out, for example, by first laying polystyrene panels having a thickness of 95 mm. Panels of a different thickness may be used, the thickness being selected generally based on the insulation needs of the specific building.
  • the wedge-cut roof insulation panels are laid out on top of these panels.
  • the panels are, for example, square having a side length of 1200 mm and a slope along one of the sides of 1:40. However, this slope may be any size, optionally depending on different required building standards.
  • the wedge-cut roof insulation panels are laid out in such a way that the roof obtains a saw-toothed or triangular profile in the longitudinal direction of the roof.
  • One example of how the saw-toothed profile is constructed is illustrated in Fig. 3 showing a cross-section of a plurality of wedge-cut roof insulation panels W10. They are laid out in the manner shown in Fig. 3, optionally in combination with support panels A1 and A2 having a thickness of 30 mm and 60 mm, respectively.
  • the saw-toothed profile may also be constructed in the manner illustrated in Fig. 4, displaying different types of wedge-cut roof insulation panels W20 and W21 fitting with each other such that an even slope is obtained, when two panels are positioned adjacent to each other. These panels shown in cross-section are also preferably square having a side length of 1200 mm and a slope along one of the sides of 1:40. To create the saw-toothed profile, laying out the roof may optionally be combined with support panels B having a thickness of 60 mm and/or 120 mm.
  • Fig. 5 shows an example of how the wedge-cut panels are laid out on a flat rectangular roof and how valley gutter wedges are positioned to created a slope towards a drain 22.
  • a section of the roof construction is shown in Fig. 6 in a perspective view.
  • the wedge-cut panels W10 are positioned in transverse direction of the roof in such a manner that this creates a slope in the longitudinal direction of the roof (shown with arrows in Fig. 5 and Fig. 6).
  • the first row of wedge-cut panels W10 (seen from the left-hand side in Fig. 5) is positioned on top of a row of support panels A1 and support panels A2, while the second row of wedge-cut panels W1 is positioned on top of a row of support panels A2.
  • the third row of wedge-cut panels W10 is positioned on top of a row of support panels A1, while the fourth row of wedge-cut panels W10 has been laid out without support panels.
  • the next four rows are positioned as "mirror images" of the first four rows and by alternately laying out the wedge-cut panels W10 in this manner with a slope towards the right-hand side and the left-hand side, respectively, a saw-toothed profile in the longitudinal direction of the roof is obtained.
  • the valley gutter wedges 20 are laid out in such a way that they create a counter slope to the saw-toothed profile while simultaneously creating a slope in the transverse direction of the roof.
  • the resulting slope direction of the valley gutter wedges 20 is shown in Fig. 5 and Fig. 6.
  • a plurality valley gutters 21 are formed having a slope (as shown with arrows) towards a row of drains 22 situated in the middle of the roof. This ensures that the roof does not contain areas where water accumulates when it rains.
  • the invention has been described with reference to a preferred embodiment. Many modifications are conceivable without thereby deviating from its scope. From Fig. 2, for example, it is apparent that the first two roof panel modules W1, W2 are always laid out together. Hence, the rupture line between the two roof panel modules W1, W2 is generally not necessary, and the two roof panel modules W1, W2 may instead be provided as a single contiguous roof panel module. It is also conceivable that two different modular panels are used to construct the valley gutter wedge. This may, for example, be a panel consisting of the four first roof panel modules W1-W4, while a second modular panel consists of two triangular roof panel modules W5. In this manner, material waste can be kept at an absolute minimum. Modifications and variations apparent to those skilled in the art are considered to fall within the scope of the present invention.
