    Title: Structural wall design BE2020 / 0026
    FIELD OF THE INVENTION The present invention relates generally to the structural design of a wall of a building, more particularly an exterior wall.
    BACKGROUND OF THE INVENTION In constructing a building, various designs have been developed for constructing a wall. For example, it is known to build a wall by laying bricks together. A particular wall type can be referred to as a frame wall: such a wall comprises a frame structure of vertical and horizontal frame members, with panels attached to one or both sides of the members. A sub-category of the frame walls can be defined based on the material used, for example wood or metal. The present invention relates to frame walls where the frame members are made as metal profiles.
    Frame members that are vertical will typically be referred to as "columns". When they extend in a horizontal direction, they will typically be referred to as "beams". The present invention relates to both columns and beams, but will be discussed specifically for columns in the following.
    Figure 1 is a schematic horizontal cross-section of a frame wall 1 comprising wall panels 4, 5 attached to both sides of a frame 2. The frame 2 comprises horizontal and / or vertical frame members which are designed as metal profiles. The cross-section of Figure 1 shows columns 3A, 3B. The profile can be closed and hollow, for example square or rectangular, as illustrated by column 3A. The profile may also be open, referred to as a C-profile, as illustrated by column 3B.
    Irrespective of the precise shape of the column profile, it can be seen that the column always has two opposite and mutually parallel flanges 31, 32. The surfaces of those flanges that face away from each other, referred to as outer surfaces 33, 34, provide mounting surfaces to which the panels 4, 5 can be attached, for example by screws that are screwed into the metal flange material; for this reason, these flanges will also be referred to as panel flanges. Their spacing determines the width or thickness of the resulting wall 1.
    Furthermore, the profile always has at least one (3B) or two (3A) body flanges 35 which extend over the entire width of the wall 1 in order to connect the panel flanges 31, 32 to each other.
    The material of the wall panels 4, 5 can be selected as desired, adequate and suitable for the purpose of the wall concerned. The space between the panels 4, 5, referred to as wall interior 6, can be left empty or can be provided with filler material, again as adequate and suitable for the purpose of the wall concerned, taking into account requirements for the wall. For example, such filler (not shown) may be insulating to provide thermal and / or acoustic insulation.
    Such a metal frame wall can be used for interior walls, but can also be used for exterior walls. When used as an exterior wall, it is to be expected that relatively large temperature differences will occur between both sides of the wall, especially during winter when the interior temperature will be perhaps 20-25 ° C while the exterior may be minus 10 or even less. Such large temperature differences are normally not expected for interior walls. In order to be able to handle such temperature differences, the wall 1 must be designed with thermal insulation in mind, and this typically involves the use of insulating material in the interior 6, for example rock wool, foam, or similar material. Depending on the expected temperature difference, the wall thickness can be adjusted, based on the consideration that thicker insulation is better insulation.
    Nevertheless, the frame members themselves, in particular the body flanges 35, form a thermal bridge, which has a negative effect on thermal insulation.
    SUMMARY OF THE INVENTION An object of the present invention is to provide a solution to the above problem. In particular, the present invention aims to provide an improved design for a frame wall with metal-based frame members, with improved thermal insulation while maintaining advantages of metal frame members, such as ease of use and structural strength.
    To this end, the present invention proposes a wall frame design in which the frame members have a composite structure of at least three components: two metal profiles defining the two wall surfaces, and a series of strong but thermally insulating connecting elements connecting these two metal profiles.
    BRIEF DESCRIPTION OF THE DRAWINGS These and other aspects, features, and advantages of the present invention will be further explained by the following description of one or more preferred embodiments with reference to the drawings, in which like reference numerals indicate the same or like parts, and in which: Figure 1 is a schematic horizontal cross-section of a frame wall according to an earlier design; Figure 2 is a schematic horizontal cross-section, similar to Figure 1, of a frame wall according to the present invention; Figure 3 is a schematic horizontal cross-section, on a larger scale, of a profile according to the present invention.
    DETAILED DESCRIPTION OF THE INVENTION Figure 2 schematically shows a cross-section, similar to Figure 1, of a frame wall 100 with frame 102, the frame 102 comprising composite frame members 200 having an assembled structure of at least three components: two metal profiles 210, 220 and a series of strong yet thermally insulating connecting elements 230 connecting these two metal profiles together. By way of comparison, Figure 2 also shows an older column 3B. In such an older column, the panel flanges 31, 32 and the body flange 35 are part of one and the same metal profile. The body flange or flanges 35 of such a profile or profiles forms a thermal bridge between the panel flanges 31, 32. Composite column 200 according to the present invention serves to replace such an older column 3B, i.e. to be used in place of such an older column. The first metal profile 210, in this case an open C-profile, comprises two opposite and mutually parallel side fringes 211, 212 and at least one body flange 213 connecting these two side flanges 211, 212. Similarly, the second metal profile 220 is an open metal C-profile, comprising two opposed and mutually parallel side flanges 221, 222 and at least one body flange 223 connecting these two side flanges 221, 222. The first and second metal profiles 210, 220 are arranged with their side flanges oriented parallel. Side flanges 212 and 222 face each other; these side flanges will be referred to as "inner flanges". The two other flanges 211 and 221 face away from each other; these side flanges will be referred to as "outer flanges", or as panel flanges, as they take over the panel mounting function from the panel flanges 31, 32 of the older column 3B.
    It should be noted that the body flanges 213 and 223 are arranged in a common plane, so that the frame structure is mirror symmetrical with respect to a virtual center plane of the wall; alternatively, one of the profiles may be mirrored so that the body flanges 213 and 223 point in opposite directions.
    It should further be noted that the two profiles 210, 220 may be of identical shape and size, but this is not essential.
    Connecting elements 230 are preferably implemented as elongated connecting bars, suitably and preferably, but not necessarily of circular cross-sectional shape. As will be explained in more detail below, each connecting element 230 has end portions 231 and 232 and a bridge portion 233 between said end portions. A first of these end portions 231 engages the two side flanges 211, 212 of the first profile 210, while a second of said end portions 232 engages the two side flanges 221, 222 of the second profile 220 for structural strength and rigidity. It is noted that this also applies if the profiles were to have a different cross-section, for instance rectangular, square, or even hexagonal or octagonal.
    In accordance with an important aspect of the present invention, the connecting elements 230, preferably along their entire length but at least partially over their bridge portion 233, are made of a thermally insulating material, in any case of a material that has lower thermal conductivity than steel.
    As far as thermal conductivity is concerned, the present invention can already be implemented with wood-made connecting elements 230. However, in view of moisture resistance, expected life, strength and stiffness, a composite material based on glass fibers in a resin has the preference.
    Figure 3 is a cross-section on a larger scale, showing preferred details of the profiles and the connecting elements. Only one profile is shown, and only the reference numerals of the first profile 210 are used, although the profile shown is mirrored upside down compared to the profile 210 in Figure 2. A connecting element 230 is shown transparent with dotted lines.
    An engagement hole 214 is made in the inner side flange 212 of profile 210. The engagement hole 214 has a size and contour corresponding to the diameter and contour of the first end portion 231 of the connecting element
    230. Although the precise diameter and contour of the first end portion 231 is not essential, it is preferred that this portion be circular in cross-section, and thus the engagement hole 214 is preferably a circular hole having a diameter corresponding to the diameter of the first. end portion 231. The hole 214 can be made by any suitable process, for example, drilling, cutting, or punching. The hole 214 may include a collar 215, as shown, but this is not essential.
    Opposite the engagement hole 214, a depression 216 is formed in the outer side flange 211, and a mounting hole 217 is made in said depression 216, aligned with the engagement hole 214. The depression 216 has a diameter that substantially corresponds to the diameter of the first end portion 231 of connecting element 230. The mounting hole 217 has a diameter less than the diameter of the first end portion 231 of connecting element 230.
    Said first end portion 231 is provided with a fastener 234 which extends longitudinally in the connecting element 230, and in any case extends up to the transverse free end face of the first end portion 231. This fastener 234 may be of a screw type for convenience. It may be a female screw type fastener, with internal thread, or it may be a male fastener type, with external thread.
    The connector 230 is coupled to the first profile 210 by introducing its first end portion 231 through the engagement hole 214 until the first end portion 231 contacts the inner surface of depression 216. The fastener 234 is aligned with the fastening hole 217. In the case of a female screw type fastener, it must cooperate with a bolt to be screwed into the fastener 234 through the fastening hole 217, in which case the screw head will be recessed in the recess 216. In the case of a screw-type male fastener, it will protrude beyond the transverse end face of the first end portion 231, through the fastening hole 217, and must cooperate with a nut to be screwed onto the fastener 234, in which case the nut is recessed into the floor 216 will be located.
    Thus, the connecting element 230 is coupled to the first profile 210 at two axially spaced positions, i.e. at the two opposite flanges 211, 212 of the profile, which makes it possible to withstand relatively large transverse forces.
    Perhaps unnecessarily, it is noted that the above description also applies to the second profile 220.
    It is further noted that there are multiple pairs of engagement holes 214 and mounting holes 217 along the length of each profile, and that both profiles 210, 220 have their respective engagement holes and mounting holes always aligned with each other for cooperation with respective connecting bars.
    It should be understood by one skilled in the art that the present invention is not limited to the exemplary embodiments described above, but that various variations and modifications are possible within the scope of the invention as defined in the appended claims. For example, instead of open C-profiles, closed square or rectangular profiles can be used.
    Even if certain features are described in different dependent claims, the present invention also relates to an embodiment that has these features in common.
    Even if certain features have been described in combination with each other, the present invention also relates to an embodiment in which one or more of these features are omitted.
    Features that are not explicitly described as essential may also be omitted.
    Reference numbers in a claim should not be construed as limiting the scope of that claim.
