Definitions

• the invention relates to roofing according to claim 1 and to a method for the manufacturing of roofing according to claim 12.
• roofs of buildings are made of several parts that, are designed for use specifically in roof structures.
• a roof structure often comprises an outer roofing material, a roof sheeting material, insulation, and a support structure or load-bearing structure that are all put together into an assembly that is mounted on the beam or purlin structure of a building.
• roof structures often need separate water-proofing. Roof structures of this type are designed for use only in roof structures.
• a problem with the above arrangement is that installing multipart roof structures of this type is a labour- and time-consuming process that considerably increases building costs.
• Known roof structures are also complex in structure.
• parts of these conventional roof structures cannot be utilised in other structures of a building. This means that known roof structures and their installation cause considerable costs.
• the roofing comprises one or more sandwich elements that comprise a first sheet forming an outer roof surface, a second sheet, and a filling material between the first and second sheets, with at least the first sheet of the sandwich element having water-proofing.
• the object of the invention is further achieved with the method described in the characterising part of claim 12 and characterised in that the method produces one or more sandwich elements that comprise a first sheet, a second sheet, and a filling material between the first and second sheets, and that water-proofing is provided at least on the first sheet of the sandwich element that forms the outer roof surface.
• the invention is based on producing the roof structure of a building, such as a hall or warehouse or any other building, by utilising elements that can also be used as wall elements or the like.
• the roof structure utilises a sandwich element or some other corresponding element or layered slab that comprises a first sheet, a second sheet, and a filling material installed between them.
• a sandwich element refers generally to all elements that comprise the above-mentioned layered structure in which a filling material, such as an insulation material, is mounted between two sheets, preferably metal sheets.
• the sandwich element is produced for instance by fastening surface sheets together by laser welding between them a profile sheet having a thermo-perforation that preferably reduces heat conduction.
• roofing is made of one or more sandwich elements that comprise a first sheet, a second sheet, and a filling material installed between them.
• Sandwich elements of this type are arranged to be installed in place such that the outer side of the first sheet, the side opposite to the filling material and second sheet, forms the outer roof surface.
• this first sheet, and especially its outer side is furnished with waterproofing that is provided on top of the outer side of the first sheet.
• Waterproofing is made preferably by laminating a water-proofing material, such as a chloropolyethylene or polyester, on the outer side of the second sheet. The lamination can be done during the manufacture of the sandwich element. This way, the water-proofing does not suffer during the other manufacturing steps.
• the sandwich element is also furnished with a load-bearing structure to support it.
• This load-bearing structure can be a metal profile sheet, corrugated sheet, smooth sheet, or any other load-bearing structure that supports the sandwich element and can be fastened on the underside of the sandwich element to the second sheet or alternatively formed in the space between the first and second sheets.
• Several water-proofed sandwich elements of this type can be attached to each other with interlocking, for instance, to form an extensive roof surface.
• the method and system of the invention provide the advantage that with the roofing structure described above, it is possible to provide quickly and easily a finished roof surface.
• the roofing structure of the invention it is possible to utilise elements and parts that are used in wall elements, for instance, so there is no need to manufacture separate elements for the roof.
• the roofing of the invention and its manufacturing method provide a simple structure and method, and consequently reduce costs.
• Figure 1 is a schematic representation of a roofing of the present invention.
• FIG. 1 shows an embodiment of the present invention, which comprises a sandwich element 2.
• the sandwich element 2 comprises a first sheet 4 and a second sheet 6 with filling material 8 installed between them.
• the first and second sheets 4, 6 are preferably made of metal, such as galvanised and/or machine-painted sheet metal or thin plate or some other corresponding material suitable for use in sandwich elements.
• the first and second sheet 4, 6 are smooth sheets that are parallel to each other.
• the first or second sheet 4, 6 or both can also be of another shape, such as wavy, profile, or corrugated sheets or the like. They then do not both need to be similar.
• the cross-profile of the filling material 8 also changes to correspond to the shape of the sheets 4, 6.
• Filling material 8 that is preferably insulating material, such as polyurethane, soft wool, hard wool, or the like, is installed between the first and second sheets 4, 6, whereby the sandwich element comprises a fixed insulation.
• the filling material 8 can also be some other material suited for installation between the sheets 4, 6 depending on the application.
• the filling material 8 can be fastened to the first and second sheets 4, 6 during the manufacture of the sandwich element 2 with glue, mechanically, or with some other corresponding method.
• the sandwich elements 2 are installed on the roof of the building in such a manner that the first sheet 4 and especially its outer surface, i.e. the surface opposite the filling material 10, forms the outer roof surface.
• this first sheet 4 has water-proofing so that it is suitable for use as an outer roof surface.
• This water-proofing can be provided with any known technique by using materials suitable for waterproofing.
• water-proofing is made by laminating a suitable water- proofing material directly on the outer surface of the first sheet 4.
• the waterproofing material to be laminated can then be chloropolyethylene (CPE laminate) or polyester (PET laminate). This way, it is possible to produce waterproofing that is an integral part of the sandwich element and especially the first sheet 4.
• water-proofing can be provided on the sandwich element 2 separately, in which case water-proofing and the structure providing it is fastened or mounted on top of the first sheet of the sandwich element 2 as a water-proofing coating.
• Water-proofing can be provided on the first sheet 4 during the manufacturing of the sandwich element 2 or during the manufacturing of the sheets 4, 6 of the sandwich element, which means that a separate process is not needed. However, it is naturally also possible to perform it as a completely separate process. Further, water-proofing can also be made on both the first and the second sheet 4, 6, whereby possible installation errors are avoided during the installation of the roofing of the invention, when the sandwich element 2 is installed the wrong way. In water-proofing it is also possible to use bitumen-based roofing or materials and especially single-layer roofing and any other known water-proofing. In addition, water-proofing can be furnished with wool, preferably hard wool, or this can be fastened to it, to settle between the first sheet 4, i.e. the top sheet, of the sandwich element 2 and the water-proofing. Wool thus provides an additional insulation.
• the ends or edges of the sandwich elements 2 preferably have interlocks 12 to join the sandwich elements 2 together.
• the interlock 12 can be of any shape, as long as the male and female interlocks of the elements 2 fit together to tightly join the sandwich elements 2 to each other.
• a machine joint 14 is provided at the joining point of the sandwich elements 2 to seal the joining point.
• the machine joint can be made with any known machine joining technique.
• this load-bearing structure is formed by fastening to the second sheet 6 of the sandwich element 2 a load-bearing structure that is formed of a load-bearing profile sheet 10.
• the profile sheet 10 is preferably fastened to the second sheet 6 by laser welding.
• the profile sheet 10 or another load-bearing structure can also be fastened to the second sheet 6 mechanically with screws, for instance, or with some other suitable fastening method.
• profile sheets can also be installed after each other, in which case they can be installed to overlap slightly as shown in Figure 1 and fastened to each other mechanically with screws, for instance, at the joining point 18.
• the load-bearing structure can be a corrugated sheet, smooth sheet, rods, beams, or any other structure that provides sufficient support for the sandwich element when it is installed on the roof of a building.
• the profile sheet can be made of a galvanised sheet, sheet metal or thin plate.
• the load-bearing structure can be formed by providing a load-bearing structure, such as a honeycomb structure, between the first and second sheets 4, 6.
• the honeycomb structure can be made of a profile sheet or corrugated sheet whose corrugations or waves extend between the first and second sheets 4, 6. This honeycomb structure can thus be fastened to both the first sheet 4 and the second sheet 6 by laser welding, for instance.
• the spaces remaining between the first and second sheets 4, 6 and the honeycomb structure are preferably filled with filling material.
• the filling material can preferably be an insulation material, such as polyurethane, soft wool, hard wool or some other corresponding insulation material.
• the profile sheet or some other corresponding load-bearing structure can also be furnished with thermo-perforation.
• the bottom sheet 6 can also act as a vapour barrier.
• roofing comprising a sandwich element with a first sheet 4 or a first sheet 4 and a second sheet 6 furnished with water-proofing.
• the sandwich element 2 is furnished with a load-bearing structure 10 to support the sandwich element 2.
