Description

BUILDING STUD COEVWRESENG FLANGE MEPJEBERS AND AN ENTERCOPJÄÉECTÉEJG WElš Fvlšfsfiêššfš AND RELATED METHOD The present invention relates to a building stud for forming a framework for mounting wall panels and to a wall structure comprising such a building stud.
WO2020/171756A1 discloses a building stud for forming a framework for mounting wall panels, comprising a first and a second flange member and a web member interconnecting the flange members. Each flange member comprises a planar, elongated wood fibre member and the web member comprises a sheet metal member including a first and a second rectilinear line of weakness, which lines of weakness are parallel and along which the sheet metal member is foldable to enable folding the building stud from a retracted storage position to an expanded mounting position. The sheet metal member comprises a first attachment section which is adjoined and attached to the first flange member, a second attachment section which is adjoined and attached to the second flange member, and a web member disposed between the attachment sections, said first line of weakness forming a boundary between said first attachment section and said web member, and which second line of weakness forming a boundary between the second attachment section and the web member. The joint between the attachment sections and the respective flange member may be a nail joint, a screwjoint, a glue joint or a combination thereof. Alternatively, or as a complement, a groove may be milled in the respective flange member, in which groove a free edge of the attachment section may be attached.
Whereas the building stud according to WO2020/171756A1 has many advantages and benefits, the joint between the attachment sections and the respective flange member may, in some applications, constitute a weakness in the design. An object of the present disclosure is to solve this problem at least partially.
Another object of the present disclosure is to provide a building stud of the aforementioned type which displays a strong joint between the attachment sections and the respective flange member. The present invention is defined by the appended claims.
According to one aspect, the present disclosure provides a building stud for forming a framework for mounting wall panels, comprising a first and a second elongated and substantially rectangular flange member and at least one web member interconnecting the flange members, wherein the at least one web member comprises a sheet metal member including a first and a second rectilinear line of weakness, which lines of weakness are parallel and along which the sheet metal member is foldable toenable the building stud to be brought from a retracted storage position to an expanded mounting position, and wherein the metal sheet member comprises a first attachment section which is attached to the first flange member, a second attachment section which is attached to the second flange member, and a web section which is arranged between the attachment sections, which first line of weakness forms a boundary between the first attachment section and the web section, and which second line of weakness forms a boundary between the second attachment section and the web section. Each attachment section comprises fasteners extending into the flange member and attaching the attachment sections to the flange member, wherein the fasteners, for each attachment section, comprise a first set of fasteners and second set of fasteners, which first and second set of fasteners are arranged parallel to each other. The âines of »weakness are forrnecš hv sections cut out or pamciwecš out front the »web section adiacent the attachment sections Eeaving bridges arranged along the âšries of »weakness and the first set ot fasteners are formed from said cut out of puriched out sections.
The first set of fasteners may be arranged along said line of weakness.
Each attachment section may comprise a substantially planar attachment sub-section and the second set of fasteners may be arranged along a longitudinal edge of the attachment sub-section.
Said fasteners may extend orthogonally to said attachment sub-section.
The first and second set of fasteners may be arranged with a mutual, orthogonal distance within the range of 2-20 mm and/or the fasteners may extend into said flange member to a depth within the range of 30% to 70% of the thickness of the flange member.
Said segç_>_ç_ggi__set_ggf'_fasteners may be formed from said sheet metal member. For example, the _s_e_çç_3__r_t__t,l_ set of fasteners may be cut out or punched out from the sheet metal member.
The attachment sections may be connected to said web member via said bridges, each bridge being arranged intermediate between two neighbouring fasteners of said first set of fasteners. Consequently, the bridges may define said lines of weakness.
Each flange member may comprise or be made from a cellulose fibre member.
According to another aseeeeeaspect, the present disclosure provides a method of producing a building stud, comprising the steps of: - forming, in a sheet metal member and parallel to each other, a first line of weakness and a second line of weakness subdividing the sheet metal member into a first attachment section, a second attachment section, and a web section, which first line of weakness forms a boundary between the first attachment section and the web section, and which second line of weakness forms a boundarybetween the second attachment section and the web section,-;- wherešn forntšne the Eines ot weakness comprises cuttšng out or ptznehšatg out sections frem the web section atäšacent the attachment sections ieavine bridges (ZS) arranged along the Ešnes of tfveakness; - forming, in each attachment section and parallel to each other, a first set of fasteners and a second set of fasteners in the sheet metal member aflfiterešat forntšnfi tite first set ot fasteners contprises torrnšrag the first set of fasteners frorn said cut out or ounched out sections; - positioning a first and a second elongated and substantially rectangular flange member side by side; emo - arranging the sheet metal member on the first and second flange members with the |inesof weakness parallel to the flange members; and - joining the sheet metal member and the first and second flange members by pressing the fasteners into the flange members.
As previously stated, each flange member may comprise or be made from a cellulose fibre member. Respective cellulose fibre member may be a panel or board of homogeneous wood or of chipboard or wood fibre laminate. However, it is to be understood that the flange members may in principle by made from any material capable of receiving and forming a joint with the fasteners. The sheet metal member may be a steel sheet having a thickness within the range of 0.3-1.5 mm. ln the storage position, the flange members may be arranged in a common plane and in the mounting position the flange members may be arranged in two parallel planes. ln the storage position, the sheet metal member may have a rectangular shape and in the mounting position a U-shaped cross section.
The lines of weakness may be provided by arranging bridges in the sheet metal member. Alternatively, the lines of weakness may be formed by embossing, i.e. by deforming the sheet metal element continuously or discontinuously along the lines of weakness. Alternatively, or as a complement, the lines of weakness may be formed by machining recesses along the lines of weakness. The lines of weakness may also, alternatively or as a supplement, be formed by partially through-cutting the sheet metal member's goods continuously or discontinuously along the lines of weakness.
Each flange member may have a substantially rectangular cross section and its cross-sectional dimensions may be customized to achieve desired performance. For example, when installing plywood and gypsum wall panels, the respective cross-sectional dimensions of the flange members may bemm wide and 15 mm thick. This width provides ample space forjoining two panel edges on the same 4 stud, while at the same time providing good conditions for securely screwing or nailing the wall panels to the flange members.
The building stud may comprise a plurality of web members, each comprising a sheet metal member. ln other words, said first and second flange members may be interconnected by a plurality of sheet metal members. This or these sheet metal members may be elongated.
According to yet another aspect, the present disclosure provides a wall structure comprising a building stud as described above.
According to yet another aspect, the present disclosure provides a method of forming a wall structure comprising a plurality of elongated building studs as discussed above. The method may comprise the steps of: - bringing each building stud, by folding the sheet metal member or members along said lines of weakness, from a retracted storage position in which the flange members are arranged in a common plane, to an expanded mounting position in which the flange members are arranged in two parallel planes; - when the building studs having been brought from the storage position to the mounting position, positioning and fixing the building studs in a framework with their respective first flange member arranged in a common plane; and - attaching one or a plurality wall panels directly or indirectly to the first flange members.
Any length adjustment of the building stud prior to mounting can advantageously be carried out when the building stud is in the storage position.
The studs can thus easily be expanded by the installer at the time of installation. The shape of the studs in the expanded position is determined by where the sheet metal member is attached to the flange members and where the lines of weakness are positioned.
The building stud may comprise a plurality of sheet metal members arranged so that the first lines of weakness are aligned along a common first rectilinear line and the second lines of weakness are aligned along a common second rectilinear line, which second rectilinear line is parallel to the first rectilinear line. ln such a case, said method of producing a building stud may comprise arranging the plurality of sheet metal members on the first and second flange members with the respective first line of weakness arranged along a common first rectilinear line and the respective second line of weakness arranged along a common second rectilinear line; and joining the plurality of sheet metal member and the first and second flange members by pressing the fasteners of the respective sheet metal members into the flange members. ln the following, embodiments of a building stud will be discussed in more detail with reference to the accompanying figures.

Figs. 1 and 5 show an embodiment of a building stud 10 according to the invention. Fig. 1 shows the building stud in a retracted storage position and Fig. 5 shows the building stud 10 in an expanded mounting position.
The stud 10 comprises a first flange member 12, a second flange member 14 and a plurality of web members 16 interconnecting the flange members 12, 14. Each flange member 12, 14 comprises a planar, elongated cellulose fibre member 18, 20, which in the illustrated embodiment has a rectangular cross-section. ln the illustrated embodiment, the respective flange members 12, 14 are formed of uniform boards of homogeneous wood, but the flange members 12, 14 may be non-uniform and/or include or be made of other types of cellulose fibre members, for example medium density fibre (MDF) board or cellulose fibre members made of chipboard or wood fibre laminate. Alternatively, the flange members 12, 14, may be made from a plastic material or any other material that allows fasteners of the web members 16 to be attached, as will be disclosed in more detail in the following.
Each web member 16 comprises an elongated sheet metal member 22. ln the embodiment shown, the sheet metal member 22 is formed from a steel sheet having a thickness of 0.5 mm.
The sheet metal member 22 comprises a first attachment section 28 which is attached to the first flange member 12, a second attachment section 30 which is attached to the second flange member 14, and a web section 32 which is disposed between the attachment sections 28,The sheet metal member 22 has a first line of weakness 24 and a second line of weakness 26 which are rectilinear and parallel (see Fig. 3). The sheet metal member 22 is plastically deformable along the lines of weakness 24, 26 to enable folding of the sheet metal member 22 along the lines of weakness 24, 26 when the building stud 10 is brought from the retracted storage position to the expanded mounting position. The first line of weakness 24 forms a boundary between the first attachment section 28 and the web section 32, and the second line of weakness 26 forms a boundary between the second attachment section 30 and the web section 32. ln the illustrated embodiment, the lines of weakness 24, 26 are formed by sections 27 being cut out from the web section 32 adjacent the attachment sections 28, 30 leaving bridges 25 arranged along the lines of weakness 24, 26. The bridges 25 are arranged along and define the lines of weakness 24, 26 and are plastically deformable to act as hinges when the sheet metal member 22 is brought from the retracted storage position to the expanded mounting position. ln the present embodiment, the bridges 25 are arranged with a mutual distance of approximately 24 mm and each bridge 25 has a length of approximately 4 mm. lt is to be understood, however, that the lines of weakness 24, 26 may be configured in other ways. For example, the lines of weakness 24, 26 may be realised by forming a groove in the sheet metal member 22, either continuously or discontinuously along the lines of weakness 24, With reference to Figs. 3 and 4, which illustrates the web member 16 without the flange members 12, 14, each attachment section 28, 30 comprises a substantially planar attachment sub-section 29, 31 and a plurality of fasteners 34, which extend substantially orthogonally from the attachment sub-section 29, 31. When mounted on the flange members 12, 14, the attachment sub-section 29, 31 abuts the flange member 12, 14 and the fasteners 34 extend into and form a joint with the flange members 12, 14 (also, see Fig. 7). ln each attachment section 28, 30, the fasteners 34 comprise a first set of fasteners 34a and a second set of fasteners 34b, which first and second set of fasteners 34a, 34b are arranged parallel to each other. lt has been found that this arrangement provides a strong joint between the sheet metal member 22 and the flange members 12, The first set of fasteners 34a is arranged along the line of weakness 24, 26 and the second set of fasteners 34b is arranged along a longitudinal edge of the attachment sub-section 29, Arranging the first set of fasteners 34a along the line of weakness 24, 26 contributes to keeping the bridges 25 flush to the flange member 12, 14 and thereby provides a well-defined line of weakness 24, 26. Also, arranging the first set of fasteners 34a along the line of weakness 24, 26 allows compressive and tensile forces in the web section 22 to be transferred directly to flange members 12, 14 via the fasteners of the first set 34a when the building stud 10 is in its expanded mounting position (e.g. see Figs. 5-7).Arranging the second set of fasteners 34b along the longitudinal edge of the attachment sub-section 29, 31 provides the largest possible separation between the first and second set of fasteners 34a, 34b. ln the present embodiment, the first and second set of fasteners 34a, 34b are arranged with a mutual, orthogonal distance D,_ which is approximately 3 mm. ln other words, the width D of the attachment sub-section 29, 31 is approximately 3 mm. From a viewpoint of nailing or screwing wall panels to the building stud 10, the distance D should be as small as possible since this minimizes the risk of nails or screws impacting on the fasteners 34 or on the attachment sub-section 29, 31 when the wall panels are mounted to the building stud (the latter if nail or screws are used having a length which is larger than the thickness of the flange member 12, 14). From a viewpoint of providing a strongjoint between the web member 16 and the flange members 12, 14, however, the distance D should be as large as possible. lt has been found that a distance D within the range of 2-20 mm provides a good compromise.
The fasteners 34 are formed from the sheet metal member 22. The first set of fasteners 34a is cut out from the web section 32 of the sheet metal member 22. The same cut-out sections 27 that define the bridges 25 also define the fasteners of the first set 34a, thus resulting in the fasteners of the first set 34a being interposed between the bridges 25. The second set of fasteners 34b are cut out from longitudinal edges of the sheet metal member 22. ln alternative embodiments, the fasteners 34 may be punched out from the sheet metal member 22 instead of being cut out.
The length and configuration of the fasteners 34 should be sufficient to securely attach the attachment sections 28, 30 to the flange members 12, 14. Preferably, the length of the fasteners 34 should be such that each fastener 34 extends into the flange members 12, 14 to a depth T within the range of 30% to 70% of the thickness of the flange members 12. 14. ln the present embodiment the fasteners 34 are provided with barbe-like structures preventing the fasteners 34 from coming out from the flange members 12, When producing the building stud 10, the fasteners 34 are cut out from a planar sheet metal member and then bent to form a right angle to the plane of the sheet metal member such that the sheet metal member 22 obtains the configuration shown in Figs. 3 and 4. The sheet metal member 22 is then joined to the flange members 12, 14 by the fasteners 34 being pressed into and attached to the flange members 12, 14, as is illustrated in Fig. 2. This is repeated for each sheet metal member 22 of the building stud Fig. 1 shows the building stud 10 in a storage position. ln this position, the flange members 12, 14 are arranged side by side in a common plane and the web section 32 of each sheet metal member 22 is arranged parallel to and on top of the flange members 12, 14. This makes it easy to transport and storethe building stud 10, since several studs can be stacked one on top of the other in a space-efficient manner.
When an installer is to mount the building stud 10 in a wall structure, he brings the building stud 10 from the retracted storage position shown in Fig. 1 to the expanded mounting position shown in Fig. 5. This is done by the installer manually rotating the flange members 12, 14 in relation to each other around the lines of weakness 24, 26 so that the flange members 12, 14 become arranged in two parallel planes. ln this movement, the sheet metal member 22 of each of the web members 16 is plastically deformed at the bridges 25, i.e. locally along the lines of weakness, which plastic deformation allows the attachment sub-sections 29, 31 to form a right angle to the web section 32, e.g. as is illustrated in Figs. 7 and 8. However, the web section 32 and the attachment sub-sections 29, 31 retain their respective planar shapes and, thus, the web members 16 obtains a substantially U-shaped cross section.
When the building stud 10 has been brought to the mounting position, the installer can arrange the building stud 10 in a wall structure framework for further attachment of wall panels.
