Definitions

  • the invention relates to an assembly for forming a roof, which assembly comprises at least two spaced-apart girders extending parallel to each other as well as roof elements being supported on said girders, whereby each roof element comprises two metal sheets extending parallel to each other, with a layer of hard foam plastic material, for example polystyrene, present therebetween, whereby said roof element can be mechanically coupled, on longitudinal sides extending between said girders, to an adjacent roof element and whereby said roof element is self-supporting in the direction of said longitudinal sides.
  • a layer of hard foam plastic material for example polystyrene
  • the invention furthermore relates to a roof element suitable for being used in such an assembly.
  • Roof elements which are built up of metal sheets with a hard foam plastic layer present therebetween are in particular suitable for spanning relatively large distances.
  • the sandwich construction makes the construction relatively strong and sturdy.
  • the roof elements are interconnected at their longitudinal sides by means of lippings, which are protected against rainwater and other weather influences by means of a suitable cover strip.
  • the lippings form relatively large protrusions on the roof to be formed, which has an adverse effect on the appearance of the roof.
  • the lippings add to the weight of the roof elements.
  • the subsequent interconnecting of said lippings and placing of a cover strip takes up a relatively great deal of time. Additionally the presence of said lippings considerably adds to the volume of the roof elements to be transported.
  • the object of the invention is to provide an assembly wherein the above drawbacks are avoided.
  • Said strip which is preferably made of the same plastic material as the plastic layer on the outside of the roof elements, can be attached to the plastic layers of the roof elements lying side by side in a simple manner, for example by means of an adhesive fluid or by means of heat, thus providing a moisture-proof transition between the roof elements lying side by side.
  • the transition between two roof elements lying side by side is practically hidden from view on the outside.
  • the provision of a seal at the location of the transition between to roof elements lying side by side in this manner can take place in a relatively quick and simple manner. It is not necessary to use a gas burner for attaching said strip to the plastic layers of the roof elements by means of an adhesive fluid or by means of heat, so that the risks involved are avoided.
  • FIG. 1 shows a building 1 consisting of a steel structure, which comprises a number of vertically extending walls 2.
  • Parallel I-sections 3 being supported on opposite walls 2 with their ends lie in the plane of the roof of building 1.
  • Roof elements 4 extend between two I-sections 3 lying side by side, said roof elements being supported on said I-sections 3 with their head ends 5.
  • Said roof elements 4 are with their long sides 6 connected to adjacent roof elements 4. Strips will be provided over the transitions between the roof elements 4, both at the location where the roof elements abut against each other with their head ends and at the location where the roof elements abut against each other with their long sides, as will be explained in more detail with reference to Figure 3, thus providing a moisture-proof sealing of the roof formed by said roof elements 4.
  • Each roof element 4 is for example 5 m long, 1.2 m wide and about 20 cm thick.
  • FIG. 2 is a perspective view of a roof element 4 according to the invention.
  • Roof element 4 comprises a layer about 20 cm thick of expanded polystyrene having a specific weight of about 20 kg/m 3 .
  • Steel sheets 8, 9 are attached to either side of said layer of polystyrene 7 by means of a glue.
  • the upper steel sheet 8 is about 0.63 mm thick and is on either side provided with a coat of zinc 10.
  • Said coat of zinc is present in an amount of about 275 g/m 2 on two sides.
  • Said steel sheet 8 is furthermore provided, on a side remote from said polystyrene layer 7, with a coat of primer 11 about 10 ⁇ m thick, to which a film of PVC 12 about 300 ⁇ m in thickness has been applied.
  • the lower layer 9 is zinc-plated in a similar manner as the upper layer 8.
  • the thickness of steel sheet 9 is about 0.5 mm.
  • Said steel sheet 9 is furthermore provided with a coat of primer 11 about 10 ⁇ m thick and a film of polyester about 15 ⁇ m in thickness.
  • a roof element 4 of this type is sufficiently strong for being placed with its head ends 5 on I-sections 3 to span for example 5 metres.
  • On a first longitudinal side 6' roof element 4 comprises a polystyrene portion which is recessed with respect to steel sheets 8, 9.
  • On a second longitudinal side 6" roof element 4 comprises a polystyrene portion which protrudes with respect to said steel sheets.
  • Steel sheets 8, 9 are flanged at longitudinal sides 6', 6". Said longitudinal sides 6', 6" will be explained in more detail hereafter with reference to Figure 4.
  • FIG 3 is a perspective view according to arrows III-III in Figure 1 of the assembly according to the invention.
  • Figure 3 shows two roof elements 4 extending towards each other with their head ends, whereby the head ends 5 are supported on an I-section 3 positioned thereunder.
  • Each roof element 4 is connected to I-section 3 by means of screws 13.
  • a space about 10 - 20 mm in width present between head ends 5 is filled with polyurethane foam 14.
  • a PVC strip 15 is provided over the ends 5, which is attached to the PVC layers 12 of the roof elements lying side by side by means of an adhesive fluid, a glue or by means of heat.
  • the portion attached to the PVC layer 12 of the roof element 4 is indicated by numeral 16.
  • PVC strips 15 are provided over the abutting longitudinal sides 6 of the roof elements 4.
  • Figure 4 is a cross-sectional view of the assembly according to the invention, seen in the direction of arrows IV-IV in Figure 1.
  • Figure 4 shows two roof elements 4, which abut against each other with their longitudinal sides 6', 6".
  • Longitudinal side 6' comprises a polystyrene portion 17, which is recessed with respect to steel sheets 8, 9.
  • Steel sheets 8, 9 are provided with a projecting portion 18 at their longitudinal sides 6', said portion 18 comprising a sheet portion 19, which is flanged back in the direction of recessed portion 17, and an end portion 20 connected to portion 19, which extends in a direction away from recessed portion 17.
  • Longitudinal side 6" comprises a polystyrene portion 21, which projects with respect to steel sheets 8,9. Projecting portion 21 is positioned between the end portions 20 of steel sheets 8, 9 of the other roof element 4.
  • the polystyrene layer is to that end recessed in the direction of its thickness near end 6".
  • the steel sheet 8 is bent in the direction of polystyrene layer 7 near longitudinal side 6", at portion 22, and continues as portion 23 from there.
  • the end of portion 23 is bent to a U-shape in the direction of polystyrene layer 7.
  • U-shaped portion 24 fits between portions 19, 20 of steel sheet 8 of the other roof element 4.
  • Steel sheet 9 is near its longitudinal side 6" provided with a portion 25 extending at an angle, which continues parallel to steel sheet 9 and which is at one end provided with a U-shaped portion 26.
  • U-shaped portion 26 fits between portions 19 and 20 of the other roof element 4.
  • the engaging steel sheets 8, 9 and the abutting polystyrene layers 7 provide a solid connection between the two roof elements 4 that abut against each other.
  • a strip 15 is provided over the transition between the two roof elements 4, as has been described with reference to Figure 3.
  • the roof obtained in this manner is of relatively simple construction and can be fitted relatively quickly.
