Description

[0001] The present invention relates to a building column for forming a framework for mounting wall panels, a wall structure including the building column, and a method for forming the wall structure.

[0002] When constructing a wall, a framework with columns is built. Horizontally, a top plate is mounted on the ceiling and a bottom plate is mounted on the floor. Then vertical columns are placed therebetween, typically spaced from each other by 450 - 600 mm. When the framework is installed, wall panels are nailed or screwed to the framework. Thus, the distance between the columns is determined by the width of the wall panels to be fixed to the columns. Common materials in wall panels are gypsum, MDF (medium density fiber), OSB (oriented strand board), particle board, and wood chips. There are also magnesium oxide, calcium silicate, fiber cement, and fiber gypsum boards, as well as various types of composite boards.

[0003] When constructing general walls, especially interior walls, columns made of steel or wood are mainly used nowadays. Wooden columns are typically homogeneous and square and are well-suited for screwing or nailing wall panels. However, wooden columns are relatively heavy and tend to warp during storage.

[0004] Steel columns are typically used in wall structures constructed using so-called light-frame construction techniques. Typically, such wall structures include a metal profile column framework forming a support or framework, which is then covered with sheet building panels. The framework includes horizontal columns forming a top plate and a bottom plate, which typically have a U-shaped cross-section. Upright columns are mounted on the top plate and the bottom plate at a predetermined distance from each other, and then the building panels are mounted on the plates and columns.

[0005] Steel columns are typically made of steel plates that are cut and bent to obtain the desired profile. Typically, a steel column includes two parallel flange members joined by a transverse web member extending substantially perpendicular to the flange members. Thus, the steel column can obtain a substantially C-shaped cross-section. Steel columns are typically made of steel plates with a relatively small thickness. For example, steel columns are typically made of steel plates with a thickness in the range of 0.4 - 0.6 mm. From a cost perspective, the thin material thickness is important, but it is also significant for sound transmission in the wall. Since a thin web part provides less sound transmission between the flange parts than a thick web part, thin steel provides better reduction of sound propagating through the wall. Another advantage associated with steel columns is that they can be "boxed" during transportation and storage, i.e., placed on top of each other. In this way, the volume occupied by the steel columns can be reduced, which is important from a storage perspective and considering expensive and environmentally harmful transportation. This is also very important in workplaces where storage space is typically lacking.

[0006] When installing wall panels in a framework, the common installation distance between nails or screws is approximately 200 mm cc at the edge portion of the wall panel and approximately 300 mm cc in the middle of the panel. The main installation method for a wooden framework is to fix it with screws, although this is more time-consuming and places a greater burden on the installer. One of the reasons is that when driving nails into a wooden track, there is a risk that the nails will be "worn out" due to the change in the shape of the wood when the humidity in the air changes. The nails that work their way out in this manner can then create visible defects on the surface of the finished wall and can also be seen through paint or wallpaper.

[0007] In a framework consisting of steel uprights, nailing is not possible because the steel is too thin for the nails to attach in the desired way. When using thin sheet uprights, there can also be problems attaching rigid wall panels to the framework by screwing. For example, in the case of rigid gypsum board, plywood, and OSB, the resistance generated when the head of the screw is mechanically embedded in the wall panel can become so great that the interaction between the screw and the steel upright causes the steel upright to deform rather than driving the screw into the upright. The thread then loses its traction in the steel upright.

[0008] The object of the present invention is to provide a novel building upright and related method that can help at least partially solve this problem.

[0009] One aspect of the present invention relates to a building upright for forming a framework for installing wall panels, the building upright comprising a first flange portion and a second flange portion and a web portion connecting the flange portions to each other. Each flange portion comprises a planar elongated wood fiber member that may have a substantially rectangular cross-section, and the web portion comprises a sheet member based on polymers and / or cellulose fibers, the sheet member including straight first and second weakening lines that are parallel, and the sheet member is foldable along the weakening lines such that the building upright can be brought from a retracted storage position to an extended installation position.

[0010] For example, the corresponding wood fiber member may be a panel or sheet of homogeneous wood or particle board or wood fiber laminate.

[0011] In principle, the sheet member can contain any polymer and / or cellulose fiber material or a combination thereof, as long as the sheet member provides sufficient strength in the extended installation position. The sheet member can, for example, comprise a thermoplastic or thermosetting sheet, such as a sheet made of ABS (acrylonitrile-butadiene-styrene monomer) or polypropylene (PP). For example, it may be preferred if the sheet member comprises an ABS sheet having a thickness in the range of 1.5 - 3.0 mm, where parallel embossing in the sheet material forms the folding lines or weakening lines.

[0012] Alternatively, the sheet member may comprise a carton or cardboard element, i.e. a rigid paper product, the manufacture of which comprises the step of dehydrating a suspension of cellulose fibres and optionally artificial fibres. The cardboard element may for example comprise a corrugated board, i.e. corrugated cardboard, the so-called fluting, with paper glued on both sides, the so-called liners. The basis weight of the cardboard material may preferably exceed 170 g / m² (paperboard), and may more preferably exceed 400 g / m² (cardboard). In the cardboard element, the weakening line may preferably be achieved by a crease line, i.e. an embossing in the cardboard material, which causes local delamination of the cardboard material layers and thus creates a hinge function.

[0013] According to yet another alternative, the sheet member may comprise a fibreboard, such as MDF (medium density fibreboard) or masonite.

[0014] The sheet member may comprise different materials that can be laminated into layers. For example, the weakening line may be formed by a flexible layer or fabric connecting rigid segments of the sheet member. For example, a fibreboard bonded to a non-woven fabric may form the sheet member in a building column according to the invention, wherein adjacent fibreboards bonded to the non-woven fabric are foldably arranged along parallel folding lines such that the building column can be brought from a retracted storage position to an extended installation position. Thus, in this embodiment, the weakening line is the folding line formed by the non-woven fabric.

[0015] The sheet member may comprise a first attachment portion adjacent and attached to the first flange portion, a second attachment portion adjacent and attached to the second flange portion, and a web portion disposed between the attachment portions, wherein the first weakening line forms a boundary between the first attachment portion and the web portion, and the second weakening line forms a boundary between the second attachment portion and the web portion. The joint between the attachment portion and the corresponding web portion may be a nail joint, a screw joint, a glue joint or a combination thereof.

[0016] Alternatively or in addition, grooves may be milled in the respective flange portions, and the free edges of the attachment portions may be attached in the grooves.

[0017] The interaction between the attachment portion and the flange portion helps to reduce, for example, the shape change of the wood fibre member in the flange portion caused by humidity changes. In other words, the attachment portion helps to eliminate or at least reduce problems that may occur when the wood fibre member settles.

[0018] The flange portions in the storage position may be arranged in a common plane, and the flange portions in the installation position may be arranged in two parallel planes.

[0019] The sheet member in the storage position may have a rectangular shape and a U-shaped cross-section in the installation position.

[0020] The weakening lines can be formed by embossing, i.e., by continuously or discontinuously deforming the sheet member along the weakening lines. Alternatively or in addition, the weakening lines can be formed by machining recesses along the weakening lines. Alternatively or in addition, the weakening lines can also be formed by continuously or discontinuously partially cutting through the article of the sheet member along the weakening lines.

[0021] Each wood fiber member can have a substantially rectangular cross-section, and its cross-sectional dimensions can be customized to achieve the desired performance. For example, when installing plywood and gypsum wallboards, the corresponding cross-sectional dimensions of the wood fiber members can be 40 mm wide and 15 mm thick. This width provides sufficient space for joining the edges of two panels on the same stud, while providing good conditions for firmly screwing or nailing the wallboard. In addition, this construction solves the problem of the movement of wood materials due to moisture and the effect on the position of nails, which usually results in homogeneous wooden studs because there is no wood at the tip of the nails. The movement of the wood material may not force the nails to disengage from their attachments, but only produce a varying "clamping" on their bodies. Of course, this assumes that the length of the nails exceeds the total thickness of the installed wallboard and the wood fiber member.

[0022] The web part can comprise one or more of the said sheet members. This or these sheet members can be elongate.

[0023] With the building stud according to the present invention, since the web members of the web part of the connecting flange part can be formed using thin sheets, a good sound insulation effect is obtained. Homogeneous wooden studs have a poor noise reduction effect because they are compact and provide a good transmission path for sound.

[0024] Another aspect of the present invention relates to a wall structure comprising a building stud as described above.

[0025] Yet another aspect of the present invention relates to a method of forming a wall structure comprising a plurality of elongate building studs, each building stud comprising a first flange part and a second flange part and a web part connecting the flange parts to each other, each flange part comprising a flat elongate wood fiber member, and wherein the web part comprises a sheet member based on polymers and / or cellulose fibers, the sheet member showing first and second straight weakening lines, the weakening lines being parallel. The method comprises the following steps:

[0026] - By folding the sheet member along the weakening lines, bringing each building stud from a retracted storage position in which the flange parts are arranged in a common plane to an extended installation position in which the flange parts are arranged in two parallel planes;

[0027] - When the building stud has been brought from the storage position to the installation position, positioning and fixing the building stud in a frame, wherein the first flange parts of the respective building studs are arranged in a common plane; and

[0028] - Attach one or more wall panels directly or indirectly to the first flange portion.

[0029] The problem of spatial requirements is solved by upright columns that allow storage and transportation in a retracted storage position. The flange portions in the storage position can be arranged in a common plane, and the web portions, which can be planar in the storage position, can be arranged to lie on the flange portions.

[0030] When the building upright column is in the storage position, any length adjustment of the building upright column can be advantageously carried out before installation.

[0031] Thereby, the installer can easily expand the upright column during installation. The shape of the upright column in the expanded position is determined by the position where the sheet member is attached to the wood fiber member and the position where the weakening line is located. Depending on requirements and the area of use, the profile of the upright column in the expanded position can be H-shaped, U-shaped or Z-shaped.

[0032] The sheet member can be elongate.

[0033] The web portion can include only one sheet member extending along the upright column.

[0034] The web portion can include a plurality of sheet members arranged such that a first weakening line is aligned along a common first straight line and a second weakening line is aligned along a common second straight line, the second straight line being parallel to the first straight line.

[0035] Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings, in which:

[0041] Figure 9 An embodiment of a building upright column according to the present invention shown in the storage position.

[0042] Figure 10 Shows a further embodiment of a building column according to the invention in a storage position.

[0043] Figure 11a and Figure 11b Show yet another embodiment of a building column according to the invention in a storage position and in an installed position, respectively.

[0044] Figure 1 Shows an embodiment of a building column 10 according to the invention. The column 10 includes a first flange portion 12, a second flange portion 14, and a web portion 16 that connects the flange portions 12, 14 to each other. Each flange portion 12, 14 includes a planar elongate wood fiber member 18, which in the illustrated embodiment has a rectangular cross-section with cross-sectional dimensions of 15 mm by 40 mm. In the illustrated embodiment, the respective flange portions 12, 14 are formed from a uniform board of homogeneous wood, but the flange portions 12, 14 may be non-uniform and include or be made of other types of wood fiber members, such as wood fiber members made of particle board or wood fiber laminate.

[0045] The web portion 16 includes an elongate sheet member 22, which has a rectangular shape and a length corresponding to the lengths of the wood fiber members 18, 20. In the illustrated embodiment, the width of the sheet member 22 is slightly less than the combined width of the wood fiber members 16, 18. In the illustrated embodiment, the sheet member 22 is formed from an ABS sheet having a thickness of approximately 2.5 mm.

[0046] The sheet member 22 has a straight and parallel first weakening line 24 and second weakening line 26, and the sheet member 22 is foldable along the weakening lines. The sheet member 22 can be plastically deformed along the weakening lines 24, 26 such that the sheet member 22 can be folded along the weakening lines. In the illustrated embodiment, the weakening lines 24, 26 are constituted by discontinuous crease lines formed in the sheet member 22 along the weakening lines 24, 26. However, the weakening lines 24, 26 can be formed in other ways, such as by through recesses or slits cut along the weakening lines 24, 26. Additionally, alternatively or in addition, the weakening lines 24, 26 can be formed by partially cutting the material of the sheet member 22 continuously or discontinuously along the weakening lines 24, 26.

[0047] The sheet member 22 includes a first attachment portion 28 that abuts and is attached to the first flange portion 12, a second attachment portion 30 that abuts and is attached to the second flange portion 14, and a web member 32 disposed between the attachment portions 28, 30. The first weakening line 24 forms a boundary between the first attachment portion 28 and the web member 32, and the second weakening line 26 forms a boundary between the second attachment portion 30 and the web member 32.

[0048] In the illustrated embodiment, the attachment portions 28, 30 are connected to their respective flange portions 12, 14 by nails 34 forming a nail joint. The connection between the attachment portions 28, 30 and the flange portions 12, 14 may alternatively be a screw joint, an adhesive joint, or a combination of nail, screw, or adhesive joints. Alternatively or in addition, grooves (not shown) may be milled in the respective flange portions, and the free edges of the attachment portions may be attached to the grooves. However, in such embodiments, the free edges must be folded 90 degrees to insert into the grooves.

[0049] Figure 1 The building column 10 is shown in the storage position. In this position, the flange portions 12, 14 are arranged side by side in a common plane, and the web portion 16, which is planar in this position, is arranged parallel to the flange portions 12, 14 and on top of the flange portions. This makes it easy to transport and store the building column 10, as several columns can be stacked on top of one another in a space-saving manner.

[0050] When the installer installs the building column 10 in a wall structure, he brings the building column 10 from Figure 1 the retracted storage position shown to Figure 2 the extended installation position shown. This is achieved by the installer manually rotating the flange portions 12, 14 relative to each other about the weakening lines 24, 26 such that the flange portions 12, 14 become arranged in two parallel planes. In this movement, the sheet member 22 is locally deformed along the weakening lines, and the attachment portions 28, 30 are allowed to form a right angle with the web member 32, as Figure 2 shown. However, the web member 32 and the attachment portions 28, 30 maintain their respective planar shapes, and thereby, the flange portion 16 obtains a U-shaped cross-section.

[0051] When the building column 10 has been brought to the installation position, the installer can arrange the building column in the wall structure 11, as Figure 3 illustrated, where the building column 10 has been placed in the track-shaped base 36 for further attachment. When the building column is in the storage position, any length adjustment of the building column 10 can be advantageously carried out before installation.

[0052] Figures 4 to 6 Alternative embodiments schematically showing alternative positions of the web portion attached to the flange portion and the weakening lines are shown. These figures show cross-sections of the columns, and the positions of the weakening lines are indicated by arrows. In the respective figures, the columns are shown in the storage position on the left and the installation position on the right.

[0053] In Figure 4 the illustrated embodiment, the web portion 16a is in the same manner as Figure 1 , Figure 3It is fixed to the flange portions 12a and 14a in the same manner as the illustrated embodiment, i.e., the weakening line is located at the central portion of the flange portions 12a and 14a. Thus, the column 10a at the installation position obtains a substantially I-shaped or H-shaped profile.

[0054] In Figure 5 the illustrated embodiment, the weakening line is offset closer to the edges of the flange portions 12b and 14b, and as a result, the column 10b at the installation position obtains a substantially U-shaped profile, but with a web member 32b having an asymmetric position.

[0055] In Figure 6 it, the web portion 16c at the storage position is folded in half on the second flange portion 14c, and the weakening line is positioned such that the web member 32c at the installation position extends diagonally between the web members 12c and 14c. This causes the column 10c at the installation position to obtain a Z-shaped cross-section.

[0056] Figure 7 Shown is a web portion 16d intended to be part of a building column embodying the invention described above with reference to Figure 1 and Figure 2 The web portion 16d includes an elongate sheet member 22d having a rectangular shape and two parallel longitudinal edges 38. In the illustrated embodiment, the sheet member 22d has a width of approximately 120 mm. However, it should be understood that the width of the sheet member 22d can be adjusted to the desired thickness of the building column at the installation position (taking into account the thickness of the flange portions). The length of the sheet member 22d is adjusted to the desired length of the building column at the storage position.

[0057] In the illustrated embodiment, the sheet member 22d has a thickness of approximately 2.5 mm. However, it should be understood that the thickness of the sheet member 22d can be adjusted to the desired strength of the building column at the installation position. Typically, the thickness of the sheet member 22d can be in the range of 1 - 5 mm, depending on the material of the sheet member.

[0058] As described above, the sheet member 22d has a straight and parallel first weakening line 24d and second weakening line 26d, and the sheet member 22d is foldable along the weakening lines to allow the building column to be brought from the storage position to the installation position. In the illustrated embodiment, the weakening lines 24d and 26d include straight indentations 40 extending along each of the weakening lines 24d and 26d. The indentations 40 are approximately 20 mm long and spaced approximately 5 mm apart. Alternatively, the weakening lines 24d and 6d can include continuous or discontinuous recesses or incisions,

[0059] The sheet member 22d includes a first attachment portion 28d intended to abut and attach to a first flange portion of a building column, and a second attachment portion 30d intended to abut and attach to a second flange portion of the building column, as described above. Therebetween, the attachment portions 28d, 30d define a web member 32d which is intended to form a flange of the building column in the installed position. Thus, a first weakening line 24d forms a boundary between the first attachment portion 28d and the web member 32d, and a second weakening line 26d forms a boundary between the second attachment portion 30d and the web member 32d.

[0060] In the illustrated embodiment, the weakening lines 24d, 26d are arranged approximately 20 mm from the respective longitudinal edges 38. However, it should be understood that the areas of the attachment portions 28d, 30d can be adjusted by placing the weakening lines 24d, 26d further from or closer to the longitudinal edges 38. For example, the areas can be adapted to the type of joint used between the attachment portions 28d, 30d and the flange portions.

[0061] The sheet member 22d can include recesses 42 for the penetration of pipes or cables. Alternatively or in addition, the sheet member 22d can include attenuation lines 44 for forming pipe or cable penetrations.

[0062] Figure 8 Shown is a web portion 16e intended to be included in a building column according to a further embodiment of the invention. In this embodiment, the web portion 16e includes a sheet member 22e which has a serrated shape but additionally has weakening lines 24e, 26e having the same function as the weakening lines described above, i.e. they divide the sheet member 22e into attachment portions 28e, 30e and an intermediate web member 32e, the attachment portions 28e, 30e being intended to abut and attach to flange portions to form a building column, and the weakening lines 24e, 26e forming lines along which the sheet member can be folded to bring the building column from a retracted storage position to an extended installed position, which is equivalent to that already described above.

[0063] It should be understood that by varying the dimensions of the flange and web members and placing the weakening lines in different positions, a variety of column configurations can be obtained.

[0064] In the above embodiments, the respective web portions include sheet members extending along the column. However, in alternative embodiments, the web portions can include a plurality of sheet members spaced apart along the column, such as Figure 9 shown.

[0065] Figure 9An embodiment of a building column 10f according to the present invention is shown. The column 10f includes a first flange portion 12f and a second flange portion 14f, as well as a web portion 16f connecting the flange portions 12f, 14f. The web portion 16f includes a plurality of sheet members 22f having weakening lines 24f, 26f, which have the same function as the above-described weakening lines, that is, they divide the corresponding sheet members 22f into attachment portions 28f, 30f and an intermediate web member 32f. The attachment portions 28f, 30f are intended to abut and attach to the flange portions to form a building column, and the weakening lines 24f, 26f form lines along which the sheet members can be folded to bring the building column 10f from the retracted storage position shown in the figure to the extended installation position, which is equivalent to that already described above. Thus, the sheet members 22f are arranged such that the weakening line 24f is aligned along a common first straight line 46f. Similarly, the weakening line 26f is aligned along a common second straight line 48f parallel to the first straight line 46f.

[0066] In Figure 9 the embodiment shown, the sheet members 22f are uniformly and symmetrically arranged in the building column 10f in the storage position. However, it should be understood that the sheet members may be non-uniformly and / or asymmetrically arranged as long as the weakening lines of the sheet members are linearly aligned to form first and second weakening lines in the web portion, thereby allowing the building column to be brought from the retracted storage position to the extended installation position. In Figure 10 an example of a building column 10g is shown, which includes a web portion 16g having sheet members 22g formed and arranged alternately, and the sheet members 22g include weakening lines 24g, 26g arranged along parallel straight lines 46g, 48g.

[0067] Figure 11a and Figure 11b Another embodiment of a building column 10h according to the present invention is shown. Figure 11a The building column 10h in the retracted storage position is shown, and Figure 11b the building column 10h in the extended installation position is shown.

[0068] The building column 10h includes a web portion 16h, which includes sheet members 22h. In this embodiment, the sheet members 22h include three sheet member segments 28h, 30h, 32h arranged edge-to-edge, and a resilient fabric 50 attached to and connecting the sheet member segments 28h - 32h. In the installation position (see Figure 11a ) the fabric 50 is arranged between the flange portions 12h, 14h and the sheet member segments 28h, 30h, 32h. The sheet member segments 28h, 30h, 32h may be cellulose fiber boards, such as MDF boards, and the resilient fabric 50 may be a fiber-reinforced fabric.

[0069] The sheet member section 28h and the portion of the fabric 50 attached thereto are adjacent to and attached to the first flange portion 12h. Thus, the sheet member section 28h forms a first fastening portion of the sheet member 22h. The sheet member section 30h and the portion of the fabric 50 attached thereto are adjacent to and attached to the second flange portion 14h. Thus, the sheet member section 30h forms a second attachment portion of the sheet member 22h. The intermediate sheet member section 32h and the portion of the fabric 50 attached thereto are not attached to the flange portions 12h, 14h.

[0070] Along the edges where the sheet member segments 28h, 30h and 32h abut against each other, the sheet member segments 28h, 30h and 32h have edges 52 that are inclined to about 45 degrees away from the fabric 50. Adjacent sheet member segments 28h, 30h, 32h are foldably arranged together along parallel fold lines 24h, 26h due to their connection to the fabric 50. This, together with the fact that the sheet member segments 28h, 30h, 32h have beveled edges 52, enables the sheet member 22h to be folded from the fabric 50. Figure 11a The sheet member sections 28h, 30h and 32h are shown arranged in a storage position in a common plane and are brought to a substantially flat position as shown. Figure 11b The beveled edges 52 of adjacent sheet member sections are shown brought into a mounted position abutting against each other and forming a support.
