  • the wall element 100' is for a building wall of the below described type, in the sense that it is specifically arranged, in terms of its dimensions and structure, to form a part of such a building wall.
  • the wall element is associated with a longitudinal direction L, a width direction W and a depth direction D. These directions in general apply also to the building wall aggregates and building walls described below.
  • the finished building wall, including any inner wall covering 604 and any outer wall covering 605, is preferably at least 20 cm thick, preferably at least 30 cm thick, and preferably at the most 50 cm thick.
  • the wall element 100' has a substantially elongated overall shape, preferably roughly a cuboid shape, and generally extending in said longitudinal direction L.
  • the wall element is arranged to be mounted between two other wall elements of the present type, in a mounted state (shown, for instance, in Figure 7), so as to form a connected, self-supporting building wall 600 extending in the width direction W with substantially no play between the wall elements 100', 100" in the width direction W.
  • the wall element 100' comprises an elongated outer support part 110, extending in said longitudinal direction L and arranged to be mounted in an exterior part 601 of the building wall 600 of which the wall element 100' forms a part.
  • "exterior” means being arranged in the part of the wall 600 facing to the exterior, such as outdoor.
  • the wall element 100' further comprises an elongated inner support part 120, also extend- ing in said longitudinal direction L and being arranged to be mounted in an interior part 602 of the said building wall 600.
  • “interior” means being arranged in the part of the wall 600 facing to the interior, such as indoor.
  • the wall element 100' comprises a distance part 130, arranged between the outer 110 and inner 120 parts, preferably separating parts 110, 120 while keeping them fixed in relation to each other.
  • the distance part 130 is hence arranged to provide a distance in said depth direction D.
  • It is also arranged to define a hollow internal space 140, between the outer 110 and inner 120 parts.
  • "internal” refers to the geometry of the wall element 100', in other words the hollow space 140 forms an element-internal, open or closed, space.
  • Figure 7 illustrates the mounted state of a wall element 100', together with other types of wall elements forming preferred parts of the building wall construction system according to the invention. This will be described in more detail further below.
  • the outer support part 110 of said wall element 100' comprises an outer longitudinally extending connecting part 111, which is arranged to be fastened to the outer support part of an adjacent wall element in said mounted state so that at least one longitudinally extending hollow external space 150 is formed along the outer support part 110 between each pair of said connected wall elements.
  • “external” refers to the wall element geometry, the hollow space 150 is hence an open or closed space which is external in relation to the rest of the wall element 100'.
  • the inner support part 120 comprises an inner longitudinally extending connecting part 121, arranged to be fastened to the inner support part of an adjacent wall element in said mounted state.
  • the total depth B of the wall element including the depth of any inner wall covering material 604 (see, for instance, Figures 8a-9c) to be mounted on the inner support part, is an even multiple of the C-C width Al between two adjacently arranged connected wall elements 100' in said mounted state.
  • the inner wall covering may be any suitable wall covering, such as wood panels; a layer of wall-covering plaster; or sheet material.
  • the wall element 100' is preferably specifically prepared for being provided with a wall covering of specified thickness, such as 13 mm plaster or 13 mm wood board plus 13 mm plaster.
  • the said C-C distance Al refers to a C-C distance between identical wall elements 100'.
  • Figures lb and lc illustrate, respectively, two additional variants 100" and 100"' of wall elements according to the present invention.
  • the wall elements 100', 100", 100"' are identical, apart from their connecting parts 110, 120 being of different width, such that their respective C-C distances A2, A4 are different from the C-C distance Al of wall element 100'.
  • the distance A4 is twice the distance A2, which in turn is twice the distance Al.
  • the total depth B is equal to the distance A4, such that the total depth B, which is the same for all wall elements 100', 100", 100"', is a respective even multiple of each one of the said three different C-C distances Al, A2 and A4 - it is one time A4; two times A2; and four times Al.
  • the total depth B of the wall element, comprising any inner wall covering 604 material is 1, 2, 3 or 4 times the said C-C width Al, A2, A4.
  • a building wall construction system according to the invention comprises wall elements 100', 100", 100"' the total depth B of which, comprising any inner wall covering 604 material, are 1, 2 and 4 times, respectively, the said C-C width A4, A2, Al.
  • all wall elements used to form one and the same building wall 600 have the same total depth B.
  • a wall element 100', 100", 100"' provides numerous advantages, as will be explained and described below, in connection to a number of detail examples. How- ever, already at this point it is worth mentioning that the design with inner and outer support parts 110, 120, with respective connecting parts 111, 121 and having a distance part 130 between them in the specified manner, in combination with the said specific geometric dimensioning of the wall element in question, achieves a wall element which is both easy to manufacture and mount, as well as provides a sturdy construction which is simple for an architect to use in the design process when drawing a building.
  • the said even multiple measurements provide the advantage that walls being constructed from the wall elements 100', 100", 100"' will form a square horizontal "pixel" grid, with a square pixel size BxB, with the possibility of sub-pixels the size AlxAl, making the layout plan of the building very easy to plan and then to translate into a finished building, while making sure that any canalization for electricity and the like ends up in a predetermined connected layout.
  • This is true both for individual building walls 600 but also to complex buildings comprising several wall element aggregates 500, 501, 502 running parallel and perpendicularly to each other. See, for instance, Figures lla-llc.
  • the term "pixel” is used to denote a smallest plannable two-dimensional horizontal geometric unit in terms of the floor plan of a building.
  • Figure 15 This is illustrated in Figure 15, in which one square is such a "pixel".
  • Figure 16 it is illustrated how the fact that individual wall elements each, when forming part of a floor plan, occupy a respective length and width that are an even pixel amount large.
  • Figure 16 also illustrates how wall elements can be set at a non 90 degree angle a (see below), and still fit the same pixel grid.
  • the dashed areas are wall elements, as seen from above.
  • measures Al, A2, A4 and B which are preferably the same for the whole floor plan, are also illustrated.
  • no corner parts are shown, for simplicity.
  • the support parts 110, 120 that carry the vertical load of the finished building wall 600, while the connecting parts 111, 121 are primarily used to permanently join individual wall elements together.
  • the distance part 130 is primarily used to provide the hollow space 140, which is arranged to be filled with insulation as described below.
  • the inner support part 120 comprises a vapour barrier 122 extending across the width W and length L of the wall element 100'.
  • the vapour barrier 122 is arranged to abut the vapour barrier of an adjacent wall element in the mounted state, so as to form a connected vapour barrier across the interior part 602 of the building wall 600.
  • the outer support part 110 comprises a wind barrier 112, extending across the width W and length L of the wall element 100' and arranged to abut the wind barrier of an adjacent wall element in said mounted state, so as to form a connected wind barrier across the exterior part 601 of the building wall 600.
  • at least one of said vapour barrier 122 and said wind barrier 112, preferably both, covers a respective side face of the wall element 100' facing in the width direction W, and preferably also a side face facing in the length direction L, which width direction-facing W side face is arranged to be pressed against a corresponding opposite side face of an adjacent connected wall element in said mounted state.
  • this is exemplified by the vapour barrier 122 running across the whole interior width W of the support part 120, from a longitudinal fastening line near the distance part 130 to another longitudinal fastening line near the distance part 130 on the other width-direction W side of the support part 120, and passing around a vertically arranged resilient strip 123 on its way.
  • the resilient strip 123 is arranged between the wall element 100' and the vapour barrier 122 in question, so that the respective vapour barriers of adjacent connected respective wall elements are pressed together against a spring force provided by said resilient strip 123 in said mounted state.
  • the resilient strip 123 may be made of rubber, silicone or other suitable durable material.
  • the vapour barrier 122 may be provided with a glue strip 124 at the location of the resilient strip 123, such as with a removable protective foil. Then, the glue strip 124 will provide proper adhesion to the vapour barrier of an adjacent wall element when the two wall elements are mounted together.
  • a resilient sealing strip may be arranged outside of the vapour barrier 122, so that the resilient strip is pressed against a corresponding resilient strip, or vapour barrier, of an adjacent connected wall element in the mounted state.
  • connection between vapour barriers 122 and/or resilient strips 123 of said two adjacent connected wall elements is arranged to be glued using a pre- installed glue strip 124 covered by a foil before mounting of the building wall 600.
  • the outer support part 110 may be provided with a wind barrier 112, such as with a resilient strip 113 and possible glue strip 114 in a way similar to the inner support part 120.
  • a wind barrier 112 such as with a resilient strip 113 and possible glue strip 114 in a way similar to the inner support part 120.
  • Each of the wind barrier 112 and the vapour barrier 122 may be a per se conventional plastic foil.
  • the wind barrier 112 and/or the vapour barrier 122 may furthermore be attached in a similar manner, such as with a respective resilient strip, along an upper or lower end of the wall element in question, in addition to on its side.
  • This provides for improved barrier function- ality when using a combination of both vertically and horizontally oriented wall elements in one and the same wall 600 (see below), since longitudinal ends of certain wall elements will then abut width-direction W facing side edges of certain other wall elements.
  • the outer 111 and inner 121 connecting parts protrude in the width direction W from the remainder of the outer 110 and inner 120 support parts, respectively, so as to cover part of the outer and inner support parts, respectively, of respective adjacent wall elements in said mounted state.
  • the outer 111 and inner 121 connecting parts protrude in opposite width directions W.
  • the connecting parts 111, 121 protrude from the distance part 130 in opposite width directions.
  • the outer 111 and/or inner 121 connecting parts are arranged to be connected to an adjacent wall element, to form said mounted state, using a fastening means which is driven through the connecting part 111, 121 in question and into the said adjacent wall element substantially in the depth direction D.
