Further, the invention relates to a method for manufacturing a stud assembly configured to be used in a building structure, and to a method for manufacturing a construction unit.
The invention is applicable to the field of building, especially the field of building structures including columns and/or beams, such as wall frames in buildings.
A well-known type of building component is a so-called light gauge steel stud. Compared to structural steel, light gauge steel is cheaper and easier to handle. On the other hand, light gauge steel can resist less heavy loads than structural steel. This means that in many practical cases, light gauge steel and structural steel are combined in a structure, wherein the structural steel is used at one or more positions in the structure so as to avoid that the loads on the light gauge steel exceed the allowable maximum. For example, when there is a heavily loaded beam supported on a light gauge steel wall panel structure and the value of the load exceeds the maximum allowable load of the light gauge steel studs in the structure, a structural steel column section is used to resist the load. The limited ability of light gauge steel to resist loads is also relevant to the practice of placing lintels over a door or a window. It is normally intended to use a light gauge steel truss lintel, wherein a large truss depth is chosen to add mechanical strength to the lintel so that the lintel is capable of resisting the load at the lintel position. However, in some situations, such as in situations in which service openings over a door or window are required, there is not enough space at the lintel position to provide a light gauge steel lintel of sufficient depth. In such situations, a structural steel beam is used instead of a light gauge steel truss lintel.
It is an object of the invention to provide a solution which enables the use of light gauge steel in situations in which conventionally structural steel would be chosen in favor of light gauge steel in view of the loads that need to be resisted, without increasing the risk of collapse of the respective structure so that the solution does not only result in a saving of costs but is also safe.
The invention provides a stud assembly that is configured to be used in a building structure, and that comprises interconnected studs in an arrangement in which longitudinal axes of the respective studs extend in a substantially parallel orientation and in which a core construction of interior studs is enveloped in an exterior construction comprising two exterior studs, wherein each of the exterior studs has a generally C-shaped cross-section, comprising two spaced flanges joined by a middle web, wherein the exterior studs are in an opposite arrangement on the core construction, with their middle webs located at first opposite sides of the core construction, and with their flanges flanking the core construction at other, second opposite sides of the core construction, and wherein each of the exterior studs is connected to the core construction. Between the core construction and the exterior construction interior spaces are present.
According to the invention, a stud assembly is provided that is an elongated building component comprising a core construction of interior studs enveloped in an exterior construction comprising two exterior studs. This exterior construction is like an exterior sleeve accommodating the core construction. As a consequence, the stud assembly has a box-like appearance.
The exterior studs are of the type having a generally C-shaped cross-section, with two spaced flanges joined by a middle web. In the stud assembly, the exterior studs are in an opposite arrangement on the core construction, which is an arrangement in which they are open to each other and enclose the core construction between them. In this arrangement, the middle webs of the respective exterior studs are located at first opposite sides of the core construction, and the flanges of the respective exterior studs are located at other, second opposite sides of the core construction. Each of the exterior studs is connected to the core construction, as a result of which a compact stud assembly is obtained, wherein the mechanical strength of the stud assembly can be higher than the total of the mechanical strength of the respective studs included in the stud assembly, and wherein the stud assembly is strong in both a longitudinal direction and directions transverse to the longitudinal direction. Hence, by providing the stud assembly, the invention provides an option of using light gauge steel in a building structure where conventionally structural steel would be used, without significantly increasing bulkiness of building components. In this respect, it is noted that it is advantageous if each of the studs of the stud assembly is a light gauge steel stud.
The present invention involves a compact, box-like appearance of the stud assembly, with interior spaces which may be used to advantage if appropriate, such as for receiving and accommodating heat insulation material. Generally speaking, it may be very practical if the stud assembly comprises heat insulation material arranged in the spaces as present between the core construction and the exterior construction. Such heat insulation material is protected from outside influences such as rain due to the enveloping character of the exterior construction.
According to one feasible option covered by the invention, the nature of the connection of the respective exterior studs to the core construction is such that at each of the first opposite sides of the core construction, the respective exterior stud is connected to the core construction at the position of its middle web. Such a connection configuration is advantageous in view of the overall mechanical strength of the stud assembly.
The core construction can be of any suitable design and can include any suitable number of interior studs. In a practical embodiment of the stud assembly according to the invention, the core construction includes two interior studs, wherein each of the interior studs is of the same type as the exterior studs, namely of the type having a generally C-shaped cross-section, comprising two spaced flanges joined by a middle web. In the core construction, the interior studs are arranged back to back and interconnected at the position of their middle webs, wherein the flanges of the respective interior studs are present at the first opposite sides of the core construction. This means that in the present embodiment, the flanges of the respective interior studs are covered by the middle webs of the respective exterior studs at the first opposite sides of the core construction.
The following options are applicable to the exterior studs, and also to the interior studs in case they are also of the type having a generally C-shaped crosssection:
1 ) the stud is of a basic, simple design in which both the middle web and the flanges have a generally planar, unbent appearance,
2) the flanges extend substantially orthogonally from the middle web,
3) edges of the flanges are provided with lips extending inwardly towards each other from the flanges, which adds to mechanical strength of the stud, and 4) if the above-mentioned lips are present, indeed, the lips extend substantially orthogonal from the flanges.
In a preferred embodiment, the exterior construction has two exterior studs of the type specified hereinabove. It is however not excluded that further element would be present. For instance, one or more spacer elements may be arranged between the two exterior studs, so as to define a distance therebetween.
Advantageously, the flanges of the respective exterior studs extend practically all the way towards each other at each of the second opposite sides of the core construction. Edges of the flanges of the respective exterior studs abut against each other or extend close to each other with a gap between them that is relatively narrow in the stud assembly, i.e. of which a width dimension is small compared to width, length and depth dimensions of the respective studs of the stud assembly. The gap as mentioned may be as small as only a few millimeters. For example, a maximum of five millimeters may be applicable. In cases in which the gap is present, indeed, the exterior construction is only interrupted to a minimal extent at the sides where the flanges of the respective exterior studs are present.
In general, it is practical if at least one and preferably all of the studs of the stud assembly are made of a single bent sheet of material, as known per se, wherein the manufacturing process may typically involve a cold-rolling action. The invention covers an option according to which the interior studs are of identical design and the exterior studs are also of identical design yet different from the interior studs at least as far as their size is concerned. In the context of the invention, the stud assembly can be of any suitable length, such as a length of several meters, and the crosssection of the stud assembly can have any suitable dimensions. The interconnection of the studs can be realized in any suitable manner. For example, connection elements such as screws of bolts and nuts can be used.
The invention also relates to a construction unit, comprising a stud assembly as defined and described in the foregoing, and further comprising two elements connected to the stud assembly at ends of the stud assembly which are opposite ends in the longitudinal direction of the stud assembly, i.e. ends of the stud assembly which are open and where it can be seen how the studs are arranged relative to each other. The elements, which will hereinafter be referred to as end elements, are functional to close the ends of the stud assembly, and possibly also to enable easy attachment to one or more other building components, which is the case when the end elements are provided with screw holes at appropriate positions, for example. In any case, for connection of the end elements to the stud assembly, it is practical if the end elements are designed to comprise two spaced connection members. For example, the connection members can be positioned to enable connection to the middle webs of the interior studs when the end elements are arranged on the stud assembly, or to enable connection to the flanges of the exterior studs when the end elements are arranged on the stud assembly.
The invention also covers a building structure comprising a stud assembly as defined and described in the foregoing, and a building structure comprising a construction unit as defined and described in the foregoing. A practical example of such a building structure is a wall frame, which can be a wall frame in a prefabricated wall or a wall frame that is erected at a building site. A practical possibility is that the building structure in which the stud assembly or the construction unit is included further comprises individual light gauge steel studs.
The invention further relates to a method for manufacturing a stud assembly configured to be used in a building structure, which method comprises the following two basic actions: providing two sets of studs, and manufacturing a stud assembly preferably having a box-like appearance, with interior spaces, from the two sets of studs with longitudinal axes of the respective studs in a substantially parallel orientation, wherein the latter basic action involves creating a core construction by interconnecting the studs of a first of the two set of studs, and creating an exterior construction enveloping the core construction and accommodating the core construction, by placing the studs of the second of the two sets of studs in opposite arrangement on the core construction and connecting the studs to the core construction. With reference to the above explanations, it is noted that the studs of the first set of studs are interior studs in the stud assembly, and that the studs of the second set of studs are exterior studs in the stud assembly. Everything that has been explained in the foregoing with respect to the number of the studs, the general nature and the shape of the studs, and the way in which the studs can be interconnected, is equally applicable in the context of the method.
In one embodiment, the exterior construction may be arranged around the core construction as a sleeve, i.e. by way of relative movement along the longitudinal direction of the stud assembly. Subsequently, the individual elements may be fastened to each other. This appears a handy way of manufacturing. Also, the method may comprise an additional action of filling the stud assembly with heat insulation material. The method can be applied as part of a method for manufacturing a construction unit, which method further comprises providing a set of two elements and connecting the elements to either the studs of the first of the two sets of studs or the studs of the second of the two sets of studs at ends of the studs which are opposite ends in a longitudinal direction of the studs.
The present invention will be further explained on the basis of the following description, wherein reference will be made to the figures, in which equal reference signs indicate equal or similar components, and in which: figure 1 diagrammatically shows a perspective side view of a stud assembly according to an embodiment of the invention, with a part of an exterior construction of the stud assembly cut away so as to provide a view on a core construction of the stud assembly; figure 2 diagrammatically shows a top view of the stud assembly; figure 3 diagrammatically shows a perspective view of a portion of the core construction; figure 4 diagrammatically shows a top view of the core construction; figure 5 diagrammatically shows a perspective view of a portion of the stud assembly, with a part of the exterior construction cut away, and an end element of a first type; figure 6 illustrates how the end element is arranged on the core construction of the stud assembly; figure 7 diagrammatically shows a perspective view of a portion of the stud assembly and an end element of a second type arranged on the stud assembly; and figure 8 illustrates how the end element is arranged on the exterior construction of the stud assembly.
The invention relates to a stud assembly that is configured to be used in a building structure. For example, the stud assembly may be useful as a column in a wall frame, as a lintel, or as a windpost in a parapet. The set-up of the stud assembly is explained in the following with reference to figures 1 and 2. It is to be noted that the embodiment of the stud assembly shown in the figures is one out of many possible embodiments covered by the invention, particularly one that constitutes a clear illustration of various advantageous aspects of the invention. The stud assembly 1 comprises two sets of studs, namely a set of interior studs 11 , 12 and a set of exterior studs 13, 14. In the present embodiment of the stud assembly 1 , all of the studs 11 , 12, 13, 14 are of a type having a generally C-shaped cross-section, with two spaced flanges 16, 17 joined by a middle web 15, wherein the interior studs 11 , 12 are of identical design and the exterior studs 13, 14 are also of identical design yet different from the interior studs 11 , 12 as far as their size is concerned. In the present embodiment of the stud assembly 1 , compared to the interior studs 11 , 12, the middle web 15 of the exterior studs 13, 14 is broader and the flanges 16, 17 extend a larger length from the middle web 15. Another option that is covered by the invention but not shown in the figures is an option according to which only the flanges 16, 17 of the exterior studs 13, 14 are larger while the middle webs 15 of all of the studs 11 , 12, 13, 14 are of the same width.
The studs 11 , 12, 13, 14 are interconnected so that the stud assembly 1 is a robust and stable entity. The studs 11 , 12, 13, 14 are in substantially parallel arrangement, which implies that longitudinal axes of the respective studs 11 , 12, 13, 14 extend in a substantially parallel orientation, and that a longitudinal direction of the stud assembly 1 corresponds to the longitudinal direction of the respective studs 11 , 12, 13, 14. In figure 1 , the longitudinal direction is indicated by means of a doubleheaded arrow L.
The interior studs 11 , 12 are arranged back to back and interconnected at the position of their middle webs 15. In this way, a core construction 2 of the stud assembly 1 is formed. The core construction 2 is separately shown in figures 3 and 4. In the context of the invention, any suitable way of interconnecting the interior studs 11 , 12 may be applied. For example, connection elements such as screws or bolts and nuts may be used in the core construction 2. Possibilities in respect of positions of such connection elements in the core construction 2, which positions will hereinafter be referred to as connection positions, are diagrammatically indicated in the figures by means of dash-dotted lines. As can be derived from the figures, it is practical if the connection positions are central on the middle web 15 in the width direction. Also, it is practical if a number of connection positions are distributed over the middle web 15 in the longitudinal direction L, and if at least two of the connection positions are located at ends of the core construction 2 which are opposite ends in the longitudinal direction L. The exterior studs 13, 14 are in an opposite arrangement on the core construction 2, with their middle webs 15 located at first opposite sides of the core construction 2, and with their flanges 16, 17 flanking the core construction 2 at other, second opposite sides of the core construction 2. In this way, an exterior construction 3 of the stud assembly 1 is obtained, which envelopes the core construction 2 and is like an exterior sleeve accommodating the core construction 2. Each of the exterior studs 13, 14 is connected to the core construction 2. In the present embodiment of the stud assembly 1 , the exterior studs 13, 14 are connected to the core construction 2 at the position of their middle webs 15, which implies that the exterior studs 13, 14 are connected to the flanges 16, 17 of the interior studs 11 , 12 at the second opposite sides of the core construction 2. In this configuration, there is no need for the exterior studs 13, 14 to be interconnected, which does not mean that an embodiment of the stud assembly 1 in which this is the case is not covered by the invention.
Also the connection of each of the exterior studs 13, 14 to the core construction 2 may be through connection elements such as screws or bolts and nuts. It is practical if all of the connections between studs 11 , 12, 13, 14 in the stud assembly 1 are realized through self-drilling screws, which does not alter the fact that the stud assembly 1 may be provided with pre-drilled holes at appropriate positions.
The stud assembly 1 comprising the core construction 2 of the interior studs 11 , 12 and the exterior construction 3 of the exterior studs 13, 14 is compact due to the way in which the studs 11 , 12, 13, 14 are put together. Creating the stud assembly 1 does not require complicated actions and can be done by providing the two interior studs 11 , 12 and interconnecting the interior studs 11 , 12 at the position of their middle webs 15, and subsequently providing the two exterior studs 13, 14, putting a first one of the two exterior studs 13, 14 in place on the core construction 2 and connecting the respective stud 13, 14 to the core construction 2 at the position of its middle web 15, and putting the second one of the two exterior studs 13, 14 in place on the core construction 2 and connecting the respective stud 13, 14 to the core construction 2 at the position of its middle web 15. If so desired, heat insulation material can be provided and arranged in spaces 21 , 22 as present between the core construction 2 and the exterior studs 13, 14. In the assembling process of the stud assembly 1 , doing so may involve placing the heat insulation material on the core construction 2 first, before putting the exterior studs 13, 14 in place on the core construction 2. Mineral wool is a practical example of the heat insulation material.
Each of the studs 11 , 12, 13, 14 of the stud assembly 1 may be a light gauge steel stud. By combining the studs 11 , 12, 13, 14 in the specific manner as described and interconnecting the studs 11 , 12, 13, 14, it is achieved that the mechanical strength of the stud assembly 1 can be higher than simply the sum of the mechanical strengths of the studs 11 , 12, 13, 14 included in the stud assembly 1. This enables application of light gauge steel studs in situations where conventionally choices in favor of applying structural steel components would be made so as to ensure sufficient mechanical strength. The stud assembly 1 is relatively light yet robust and can be considerably cheaper than a structural steel component. When it comes to mechanical strength, an advantageous fact about the stud assembly 1 is that the studs 11 , 12, 13, 14 are included in the stud assembly 1 in different orientations about a general longitudinal axis of the stud assembly 1. In particular, in the present embodiment of the stud assembly 1 , the orientations of the respective interior studs 11 , 12 about the general longitudinal axis differ 180°, and likewise, the orientations of the respective exterior studs 13, 14 about the general longitudinal axis differ 180°, while the set of interior studs 11 , 12 and the set of exterior studs 13, 14 are 90° rotated relative to each other about the general longitudinal axis. It is a general fact that C-shaped studs are considerably stronger in one direction than another, and it appears that in the stud assembly 1 , the studs 11 , 12, 13, 14 reinforce each other on the basis of the way they are orientated differently about the general longitudinal axis of the stud assembly 1 .
In the present embodiment of the stud assembly 1 , edges of the flanges 16,
17 of each of the studs 11 , 12, 13, 14 of the stud assembly 1 are provided with lips
18 extending inwardly towards each other from the flanges 16, 17. This is not essential but adds to mechanical strength. Further, in the present embodiment of the stud assembly, the lips 18 of the flanges 16, 17 of the interior studs 11 , 12 abut against the flanges 16, 17 of the exterior studs 13, 14. In the case that the flanges
16, 17 of the interior studs 11 , 12 are provided with lips 18, this is also a non- essential feature of the stud assembly 1 , but may be a preferred feature in view of mechanical strength. Likewise, in the case that the flanges 16, 17 of the exterior studs 13, 14 are provided with lips 18, it is possible that the lips 18 of the one exterior stud 13, 14 abut against the lips 18 of the other exterior stud 13, 14, but it is also possible that a gap is present at the positions where edges of the flanges 16, 17 of the exterior studs 13, 14 face each other, which gap is preferably relatively narrow in the stud assembly 1 so that the stud assembly 1 has an overall closed appearance with only two relatively narrow longitudinal gaps, while only the ends of the stud assembly 1 which are opposite ends in the longitudinal direction L are open. End elements may be used to close those ends, as will be explained in the following with reference to figures 5-8.
In figures 5 and 6, an end element 4 of a first type is shown. The end element 4 comprises a base plate 41 and two spaced connection members 42, 43 extending in a central area of the base plate 41 at one side of the base plate 41 and at a distance from each other. As shown, it is practical if the connection members 42, 43 are plates as well. Further, as shown, it is practical if all of the base plate 41 and the connection members 42, 43 have a rectangular circumference. The invention covers any possible option when it comes to the way in which the connection members 42, 43 are attached to the base plate 41 . In the practical case that the end element 4 comprises a metal material, the attachment referred to may be through welding.
The end element 4 of the first type is configured to be connected to the core construction 2 of the stud assembly 1. The distance between the connection members 42, 43 is chosen so as to enable the connection members 42, 43 to snugly receive an end area of the interconnected middle webs 15 of the interior studs 11 , 12 between them, as illustrated in figure 6. Once the end element 4 is in place on the stud assembly 1 , the end element 4 is connected to the core construction 2 at the position of the connection members 42, 43 in a suitable way, such as by using bolts and nuts at appropriate positions, as diagrammatically indicated in figure 6 by means of dash-dotted lines. In this respect, it is practical if the connection members 42, 43 are provided with holes 44, as shown in figures 5 and 6, which does not alter the fact that the invention covers other options including the use of self-drilling screws so that there is no need for pre-drilled holes. The size of the base plate 41 may be adapted to the cross-sectional size of the stud assembly 1 , but it is also possible that the size of the base plate 41 is larger than that, so that one or more areas of the base plate 41 extend beyond the stud assembly 1 in a direction transverse to the longitudinal direction L. Application of the latter option enables easy connection of the base plate 41 to one or more other building components if so desired. In a process of manufacturing a construction unit 6 comprising a stud assembly 1 and at least one end element 4 of the first type, it is practical if the following sequence of actions is realized: first, making the core construction 2, second, connecting the end element 4 to the core construction 2, and third, putting the exterior studs 13, 14 in place on the core construction 2 and connecting the exterior studs 13, 14 to the core construction 2.
In figures 7 and 8, an end element 5 of a second type is shown. Like the end element 4 of the first type, the end element 5 of the second type comprises a base plate 51 and two spaced connection members 52, 53. In the end portion 5 of the second type, compared to the end portion 4 of the first type, the base plate 51 is larger in one direction transverse to the longitudinal direction L and also the distance between the connection members 52, 53 is larger. The fact is that the end element 5 of the second type is configured to be connected to the exterior construction 3 of the stud assembly 1. The distance between the connection members 52, 53 is chosen so as to enable the connection members 52, 53 to snugly receive an end area of the stud assembly 1 between them, as illustrated in both figures 7 and 8. In the present example, when the end element 5 is in place on the stud assembly 1 , the connection members 52, 53 flank the exterior construction 3 at opposite sides where the flanges 16, 17 of the exterior studs 13, 14 are present. As is the case with the end element 4 of the first type, it is practical if the connection members 52, 53 are provided with holes 54 for receiving and accommodating suitable connection means, yet not essential. Further, it is practical if the base plate 51 is provided with holes 55, for facilitating connection of the construction unit 6 to one or more other building components. This is also a non-essential feature of the end element 5.
As explained, using end elements 4, 5 on the stud assembly 1 is a way of enabling connection of the stud assembly 1 to one or more other building components. Additionally or alternatively, it is possible that one or more other building components are directly connected to the stud assembly 1 , such as by means of screws arranged through both the respective building components and the exterior construction 3 of the stud assembly 1 . Practical examples of other building components are wall panels, which may include studs along their upright edges.
It will be clear to a person skilled in the art that the scope of the present invention is not limited to the examples discussed in the foregoing, but that several amendments and modifications thereof are possible without deviating from the scope of the invention as defined in the attached claims.

At least each of the exterior studs 13, 14 has a generally C-shaped cross-section, comprising two spaced flanges 16, 17 joined by a middle web 15. The exterior studs 13, 14 are in an opposite arrangement on the core construction 2, with their middle webs 15 located at first opposite sides of the core construction 2, and with their flanges 16, 17 flanking the core construction 2 at other, second opposite sides of the core construction 2, wherein each of the exterior studs 13, 14 is connected to the core construction 2.
