Definitions

  • This invention relates to a sandwich building element comprising a mineral wool core between surface layers of metal, which element at one ore more positions can be bent to the desired angle.
  • This invention also relates to a process for manufacturing a sandwich building element according to the above.
  • This invention further also relates to the use of the above mentioned sandwich building element and of the above mentioned process.
  • Ready-bent building elements occupy a lot of space during transportation to the construction or installation site and therefore produce unnecessarily high transport costs.
  • Some examples of such building elements are corner elements for applications as external walls, internal walls, encapsulation of e.g. pipes, pillars, etc. The applications are many.
  • Ready-bent building elements also raise the risk of transport damages as well as damages at the construction site, and it is more difficult to design the standard packaging for the transportation for these.
  • the purpose of the present invention is therefore to eliminate unnecessary transport costs and to reduce the risk of transport damages as well as damages at the construction site, especially as regards sandwich building elements comprising a mineral wool core between surface layers of metal, since this is an important field of business to the inventors and the holder of the present invention.
  • the sandwich building element according to the invention is characterised by that the sandwich element on at least one side has at least one interruption in the surface layer, which interruption(s) extends over the whole side in question, and at least one cut in the mineral wool core for enabling bending of the sandwich element into the desired angle.
  • the process according to the invention is characterised by that the sandwich element on at least one side is provided with at least one interruption in the surface layer, which interruption(s) extends over the whole side in question, and at least one cut in the mineral wool core for enabling bending of the sandwich element into the desired angle.
  • sandwich building element according to the invention is characterised by that the sandwich building element after transportation in essentially planar position to the contruction site is bent and locked at the desired angle(s) at the construction site.
  • the process according to the invention is used for manufacturing a sandwich building element according to the invention.
  • the benefits of the invention are hence that the transport costs and the risk of transport damages as well as damages at the construction site for sandwich building elements comprising a mineral wool core between surface layers of metal is noticeably reduced. Because of the fact that ready-angled elements occupy more space and that it is not possible to load anything else on the same package cargo, the transport costs will be higher for angled than for non-angled elements. Thanks to the invention, one can now obtain much lower packaging costs for the standard packaging of the elements, because they are not angled until after the transportion to the construction site. Other significant advantages of the invention are that one makes savings in the transport design and that it furthermore is much easier to design the standard packaging for the transport.
  • the sandwich building iatat is characterised by that the cut(s) is (are) cuneate.
  • the cuts may however have any other form.
  • the sandwich building element according to the invention is characterised by that the angle and the depth of each cut and the number of cuts are chosen depending on the desired bending angle.
  • the sandwich building element according to the invention is characterised by that there for the inner corner of each bending is available a corresponding corner moulding or angel moulding with a corresponding length and angle as well as locking members for locking the sandwich element at the angel in question.
  • the locking members may for example be conventional screws.
  • the sandwich building element according to the invention is characterised by that the mineral wool core of the sandwich building element is made of rock wool. Also other kinds of mineral wool may however be used.
  • a preferred embodiment of the process according to the invention is characterised by that the cut(s) are shaped cuneatly. This can for instance be done with a compass saw, but also other cutting tools can be used.
  • Another preferred embodiment of the process according to the invention is characterised by that the angle and the depth of each cut and the number of cuts are chosen depending on the desired bending angle.
  • each bending is provided with a corresponding corner moulding with a corresponding angle and locking members for enabling locking of the sandwich element at the angel in question. If the angle of the sandwich element is 90°, then the corner moulding's angle is hence also 90°.
  • Another preferred embodiment of the process according to the invention is characterised by that the mineral wool core is made of rock wool.
  • a single sandwich element can according to the invention also be provided with several places of cuts which enable forming of several corners or angles of different angle sizes where the angles can be acute as well as blunt.
  • the number, angles, depth as well as shape of the cuts may take different forms according to specific needs.
  • a sandwich element according to the invention can be achieved e.g. by at first producing in a conventional way a sandwich element comprising a mineral wool core between continous surface layers of metal, and then by according to conventional methods cutting out and removing the cut-out sheet or strip of metallic surface layer as well as cut-out mineral wool.
  • FIG 1 a preferred embodiment of the invention i.e. a sandwich building element 1 comprising a mineral wool core 2 between surface layers 3 of metal.
  • the sandwich element 1 shows four cuts 4 in the mineral wool core 2, which form a zic-zac-shaped cut profile with three sharp crests 4a and four sharp throughs 4b.
  • the angle between the side legs of the apex of a crest 4a or the apex of a through 4b is in this example 22,5° (does not totally agree with the figure).
  • This cut 4 enables bending of the sandwich element 1 into an angle of 90°.
  • Figure 1 also shows that the sandwich element 1 has male elements 6 and female elements 5 for connecting of several sandwich elements 1 to each other. The dimensions of the sandwich element 1 are chosen depending on the construction purpose.
  • FIG 2 In figure 2 is shown a sandwich element 1 according to figure 1, which after transportation in planar position to the construction site at the construction site is bent into the desired angle of 90° and is firmly locked at this angle with a corner or angle moulding 7 and locking members 8 (e.g. screws).
  • This corner moulding 7 has the same length (i.e. has the length Y, see figure 3) as the length Y of the interruption X between the two opposing edges.
  • figure 3 is shown an example on how sandwich elements 1 according to figure 1 can be transported from the production site to the construction site in order to there then be bent into the desired angle (in this example an angle of 90°), installed and locked in position according to figure 2.
  • desired angle in this example an angle of 90°
  • Figure 3 also shows that the interruption X has the length Y and extends itself linearly and with even width over the whole side from one edge to its opposing edge.
  • the interruption X which extends itself between the two opposing edges, in other words has the length Y.
