Definitions

  • the invention relates to a wall structure comprising panels arranged on top of one another and side by side.
  • a problem with known wall structures comprising panels fixed to a support structure supporting the wall, such as steel structures or composite columns, is that heavy and long bolts extending over the thickness of the panel are needed.
  • the structure is prone to cause bending forces to the bolts. Sometimes this may cause that panels settle or even collapse.
  • the bending forces focusing to the bolts are significant especially when panels arranged side by side are fixed with a bolt plate held in place by a single bolt that is attached between the panels through a vertical panel seam, i.e. in this case the bolt is not penetrating the panel surface itself.
  • Ongoing tendency towards increasing panel thicknesses is intensifying the problem.
  • a wall structure comprising
  • the wall structure is characterised by what is stated in the independent claim. Some other embodiments are characterised by what is stated in the other claims. Inventive embodiments are also disclosed in the specification and drawings of this patent application.
  • the inventive content of the patent application may also be defined in other ways than defined in the following claims.
  • the inventive content may also be formed of several separate inventions, especially if the invention is examined in the light of expressed or implicit subtasks or in view of obtained benefits or benefit groups. Some of the definitions contained in the following claims may then be unnecessary in view of the separate inventive ideas.

  • the wall support structure comprises connection points arranged on top of one another, and the first attachment part is attached to one of the connection points.
  • An advantage is that building of the wall structure may be simplified, and the connection points may be provided with threads to enable even more easy assembly.
  • a second attachment hole is arranged in the second attachment part, said hole being aligned with the shaft part, and a second fastening means is arranged through the second attachment hole, said second fastening means extending in the vertical panel seam to the wall support structure and fastened thereto.

In one embodiment, such as shown in the Figures, the second attachment part 7 is attached to two composite panels 1 having the vertical panel seam 2 therebetween.
  • the second attachment part 7 has two functional tasks: firstly, it transmits at least part of the weight of the panel to the wall support structure 4 via the shaft part 8 and the first attachment part 6, and secondly, it prevents together with a second fastening means 12 the panel 1 from loosening or coming off from the wall support structure 4 due to a suction effect caused by wind.
  • Said second fastening means 12 may comprise e.g. a bolt arranged through a second attachment hole 11 and extending in the vertical panel seam 2 to a threaded hole 14 in the wall support structure 4.

  • the first attachment part 6 having the mounting hole 9 is fixed to the wall support structure 4 by a socket (not shown) comprising an inner thread that is screwed on the connection point 13.
  • the socket has an excess length of the inner thread not occupied by the external thread of the connection point.
  • the second and the third fastening means 12, 18 may then be fixed to said socket.

  • the support plates 20 alternate with the second attachment parts 7 on the vertical panel seam 2.
  • the support plates 20 have different dimensions as the second attachment parts 7.
  • this is not always necessary, i.e. the support plates and the second attachment parts may have identical dimensions.
  • the shapes of the support plates and the second attachment parts are not necessarily quadrangular.
