Description

SUPPORT ASSEMBLY

[0001] The present disclosure relates to a support assembly for providing structural support to a through-hole to be formed in a stud wall. The present disclosure also relates to a method for providing structural support to a through-hole to be formed in a stud wall.

Background

[0002] Certain walls of a building structure may be stud walls. For example, a stud wall has a plurality of studs in the form of solid vertical columns comprising wood or metal. Either side of the studs may be wall panels which define the faces of said wall. In some examples, during the process of constructing the wall and/or the building structure, it may become necessary and/or desired to create a through-hole in the stud wall. For example, it may be decided after construction of the stud wall that a window is to be installed in the stud wall. For example, it may be decided that a through-hole is needed to provide access, such as access for wires, plumbing, or other components that relate to providing and/or monitoring services to the building structure. For example, a through-hole may be desired to install a ventilation or air conditioning system. These are merely examples, and those skilled in the art will appreciate the various reasons for creating a through-hole in a stud wall.

[0003] If the through-hole is to be created after construction of the stud wall has been completed, there is a problem in that it may be necessary to deconstruct all or part of the stud wall in order to install the through-hole. This not only incurs additional costs and wastes materials but can result in delays in the building process as additional supplies and resources need to be dedicated to rebuilding said wall. This may also result in delaying other deadlines which rely on completion of this wall or if resources are being redirected to rebuild the wall.

[0004] Those skilled in the art will also appreciate that structures made as part of a building structure should meet certain standards, for example, fire safety standards and robustness, among others. Accordingly, it would be more desirable that certain structural and safety standards (in some cases, necessary rather than merely desired, depending upon the local building regulations) continue to be met after alterations, such as a through-hole, are made to the structure in question.

[0005] The present disclosure seeks to provide solutions to at least some of these problems, among other advantages, as will become apparent from the following description. -2 -

Summary

[0006] According to a first aspect of the present disclosure, there is provided a support assembly for providing structural support to a through-hole to be formed in a stud wall, the support assembly comprising: a first bridge portion and a second bridge portion, the first and second bridge portions each configured to be fixed to studs of the stud wall via a first face of the stud wall wherein each of the first and second bridge portion: is elongate and comprises a first connection portion and a second connection portion such that when the first connection portion overlaps a first stud of the stud wall, in an in-use position and orientation on the first face, the second connection portion overlaps a second stud of the stud wall; a plurality of filler pieces for being positioned in cavities of the stud wall at a set of through-hole boundary faces, the set of through-hole boundary faces being created when the through-hole has been formed in a region of the wall delimited by the first and second bridge portions in their in-use position and orientation on the first face; and a plurality of boards configured to be fixed to the plurality of filler pieces and to cover up the set of through-hole boundary faces.

[0007] Advantageously, there is provided a support assembly which can be deployed to structurally support a through-hole that is to be formed in a stud wall. For example, the first and second bridge portions may be deployed onto the stud wall to delimit the desired through-hole position, even before the through-hole is made. For example, the first and second bridge portions may be installed above and below a region where the through-hole is to be formed. Furthermore, the filler pieces provide structure (where there would otherwise be cavities) to which other components (boards) of the support assembly can be fixed. Accordingly, the support assembly can be fixed so that a through-hole may be formed in the stud wall and the stud wall can retain sufficient structural integrity. The first and second connection portions are spaced so as to both be fixed to wall studs. In this manner, the first and second bridge portions can be robustly fixed, and provide great support to a region delimited by (e.g., between) the first and second bridge portions. Furthermore, the boards provide a barrier to the interior of the stud wall which may prevent unwanted objects from entering the cavities within the stud wall. The boards can also provide a more aesthetically pleasing finish. Additionally, the boards can provide further structural integrity to the stud wall.

[0008] Optionally, the first and second bridge portions form opposing sides of a support frame, and the support frame further comprises: a first side portion which connects the first connection portion of the first bridge portion to the first connection portion of the second bridge portion; and a second side portion which connects the second connection portion of the first bridge portion to the second connection portion of the second bridge portion. -3 -

[0009] For example, while in some examples, the first and second bridge portions may be separate pieces and may be deployed as such. In some examples, the bridge portions are part of a support frame which can surround the region where the through-hole is to be formed.

Structural integrity is advantageously further enhanced by providing a connected-up support frame.

[0010] Optionally, the support frame forms a rectangle surrounding the through-hole to be made in the stud wall. Advantageously, providing the support frame as a rectangle increases the structural integrity of the stud wall comprising the through-hole.

[0011] Optionally, the support frame comprises a plurality of support frame segments configured to be assembled to provide the support frame.

[0012] Advantageously, providing the support frame as a plurality of segments makes the support frame easier to manufacture and to transport to the site of installation. In addition, the support frame being comprised of a plurality of segments may also be easier to install. Furthermore, the support frame can be built up to the required size using the plurality of segments, while maintaining that each of the first and second sections of the support frame overlap studs of the stud wall.

[0013] Optionally, the support assembly comprises: a third bridge portion and a fourth bridge portion, the third and fourth bridge portions each configured to be fixed to studs of the stud wall via a second face of the stud wall opposite the first face, wherein each of the third and fourth bridge portion: is elongate and comprises a first connection portion and a second connection portion such that when the first connection portion overlaps the first stud, in an in-use position and orientation on the second face, the second connection portion overlaps the second stud.

[0014] Advantageously, structural support can be provided at both sides of the stud wall. For example, similarly to the above discussed examples of the first and second bridge portions, the third and fourth bridge portions may also form another support frame. The support assembly can therefore comprise a first support frame and a second support frame that can be deployed on either side of the stud wall and secured to the studs in the stud wall to further structurally support a through-hole that is to be formed in the stud wall. The second support frame provides additional structural integrity compared to that provided by the support frame alone.

[0015] Optionally, the first and second bridge portions comprise a plurality of holes configured to receive fixings for fixing the support frame to at least the first and second studs. -4 -

[0016] Advantageously, there are provided sites at which fixings can be deployed on the support frame, thus simplifying installation. Manufacturing the support frame to include such sites for the fixings removes the requirement to work a fixing through the frame during installation.

[0017] Optionally, at least some of the plurality of holes are slotted holes.

[0018] Advantageously, the slotted holes provide an allowable level of tolerance regarding the placement and type of fixing used to secure the support frame, thus further simplifying installation.

[0019] Optionally, each of the first and second bridge portions comprises: a first planar section; and a second planar section configured at a non-zero angle relative to the first planar section.

[0020] Advantageously, this provides the support frame with additional structural integrity. For example, the first and second planar section being at a non-zero angle to one another means that the support frame is not merely a flat plate. For example, by not merely being a flat plate, the support frame may have enhanced strength.

[0021] Optionally, the non-zero angle is such that the first and second planar sections are perpendicular to one another; and a first surface of the first planar section is configured to face the first face of the stud wall.

[0022] Advantageously, this configuration provides the support frame with an L-shaped cross-section, which provides enhanced structural strength. Advantageously, this also provides a structural feature (i.e., the second planar surface) to which an additional feature (i.e., fire-retardant material such as a fire-retardant batten) may be secured to improve certain properties (i.e., fire resistance) of the stud wall.

[0023] Optionally, the support assembly comprises: a set of fire-retardant battens configured to cover surfaces of the first and second planar sections other than the first surface of the first planar section, and surfaces other than those having a lateral dimension equal to the thickness of the respective planar section.

[0024] It will be appreciated that the creation of the through-hole in the stud wall would diminish the fire rating of the stud wall. However, advantageously, the fire-retardant battens serve to re-enhance/reinstate the fire integrity of the stud wall.

[0025] Optionally, the first and second bridge portions comprise steel. -5 -

[0026] Advantageously, steel may provide a high level of structural strength while also inhibiting the progress of fire. For example, steel may also be able to be formed into desired shapes and the like using easy to implement processes and techniques. Furthermore, there are types of steel available which are resistant to corrosion, for example, galvanised steel or stainless steel.

[0027] Optionally, the filler pieces comprise wood or steel.

[0028] Advantageously, wood or steel is suitable for receiving fixing and remaining steadfast to support a structure (i.e., boards) fixed thereto.

[0029] Optionally, the plurality of boards is fire retardant.

[0030] Advantageously, such boards re-enhance/reinstate the fire integrity of the stud wall that may have been compromised by the creation of the through-hole.

[0031] According to a second aspect of the present disclosure, there is provided a method for providing structural support for a through-hole to be formed in a stud wall, the method comprising deploying onto the stud wall a support assembly, the support assembly comprising: a first bridge portion and a second bridge portion, the first and second bridge portions each configured to be fixed to studs of the stud wall via a first face of the stud wall, wherein each of the first and second bridge portion: is elongate and comprises a first connection portion and a second connection portion such that when the first connection portion overlaps a first stud of the stud wall, in an in-use position and orientation on the first face, the second connection portion overlaps a second stud of the stud wall; a plurality of filler pieces for being positioned in cavities of the stud wall at a set of through-hole boundary faces, the set of through-hole boundary faces being created when the through-hole has been formed in a region of the wall delimited by the first and second bridge portions in their in-use position and orientation on the first face; and a plurality of boards configured to be fixed to the plurality of filler pieces and to cover up the set of through-hole boundary faces.

[0032] Advantageously, the method according to the second aspect allows the advantages of the disclosed structural support assembly to be realised.

[0033] Optionally, the method according to the second aspect comprises: prior to forming the through-hole, fixing the first connection portion of the first bridge portion and the first connection portion of the second bridge portion to the first stud through a wall panel forming the first face, and fixing the second connection portion of the first bridge portion and the second connection portion of the second bridge portion to the second stud through the wall panel forming the first face; and subsequently forming the through-hole within an area of the first face delimited by the -6 -first and second bridge portions, the through-hole having a size smaller than the area of the first face delimited by the first and second bridge portions.

[0034] Advantageously, the first and second bridge portions are fixed to studs without having to first perform any alteration to the stud wall. The through-hole is cut after the bridge portions have already been installed and is therefore supported straight away. Advantageously, the through-hole can be of any size within the area delimited by the first and second bridge portions.

[0035] Optionally, the method according to the second aspect comprises: positioning and securing the filler pieces in the cavities of the stud wall at the set of through-hole boundary faces.

[0036] Advantageously, the filler pieces provide further structure (where there would otherwise be cavities) to which other components (boards) of the support assembly can be fixed.

[0037] Optionally, the method according to the second aspect comprises: fixing the boards to the filler pieces to cover up the set of through-hole boundary faces.

[0038] Advantageously, the boards provide a barrier to the interior of the stud wall which may prevent unwanted objects from entering the cavities within the stud wall. For example, the boards close off the cavity to fire. In other words, in the event of a fire the boards prevent said fire from entering the cavities and compromising the wall. The boards can also provide a more aesthetically pleasing finish. Additionally, the boards can provide further structural integrity to the stud wall.

Detailed Description

[0039] According to examples, there is provided a support assembly for providing structural support to a through-hole to be formed in a stud wall. In examples, the support assembly comprises a first bridge portion and a second bridge portion, the first and second bridge portions each configured to be fixed to studs of the stud wall via a first face of the stud wall. In examples, each of the first and second bridge portions is elongate and comprises a first connection portion and a second connection portion such that when the first connection portion overlaps a first stud of the stud wall, in an in-use position and orientation on the first face, the second connection portion overlaps a second stud of the stud wall.

[0040] In examples, the support assembly also comprises a plurality of filler pieces for being positioned in cavities of the stud wall at a set of through-hole boundary faces, the set of through-hole boundary faces being created when the through-hole has been formed in a region of the wall delimited by the first and second bridge portions in their in-use position and orientation on the first face. The support assembly also comprises a plurality of boards configured to be fixed to the plurality of filler pieces and to cover up the set of through-hole boundary faces.

[0041] Figure 1 is a first simplified schematic front view of the first and second bridge portions, according to examples. In these examples, there is the first bridge portion 107 and the second bridge portion 109. For simplicity of description, not all the elements of the support assembly are shown. However, there are shown example first and second wall studs 602a, 602b. The studs 602 are shown in dashed lines as they lie behind a first face 104 of a stud wall 106.

[0042] In these examples, the first bridge portion 107 has the first connection portion 107a which overlaps the first stud 602a, and the second connection portion 107b which overlaps the second stud 602b. In this way, the first bridge portion 107 is configured to be fixed to both the first and second studs 602a, 602b. For example, the length of the elongate first bridge portion 107 (including the first and second connection portions 107a, 1076) may be equal to, cr similar to, an integer multiple of the outside-to-outside stud spacing. It should be noted that the length can be somewhat smaller than the outside-to-outside stud spacing, however, it is not desired to be less than the inside-to-inside stud spacing as this would omit simultaneous overlap between the first bridge portion 107 and both the first and second studs 602a, 602b. The second bridge portion 109 has the same configuration with its respective first 109a and second 109b connection portions.

[0043] It will be appreciated that the first and second studs 602a, 602b may not necessarily be adjacent studs (although in some examples they may be). For example, there could be a stud 602 positioned between the first and second studs 602a, 6026. This depends, for example, on the desired size of the through-hole to be made in the stud wall 106.

[0044] In the examples of Figure 1, the first and second bridge portions 107, 109 are two separate pieces which are oriented horizontally, in use, as shown in Figure 1. For example, the first and second bridge portions 107, 109 may be aligned one above the other, for example. The first and second bridge portions 107, 109 serve to create a link between two studs. The region delimited by the first and second bridge portions 107, 109 may be a region which is between the first and second bridge portions 107, 109.

[0045] In some examples, the first and second bridge portions form opposing sides of a support frame. For example, the first bridge portion 107 forms a top side of the support frame in the in-use orientation and position, and the second bridge portion 109 forms a bottom side of the support frame in the in-use orientation and position. In these examples, the support frame comprises a first side portion which connects the first connection portion of the first bridge portion to the first connection portion of the second bridge portion, and a second side portion which connects the second connection portion of the first bridge portion to the second connection portion of the second bridge portion.

[0046] In this manner, there may be provided a support frame, as part of the support assembly, which incorporates the first and second bridge portions 107, 109. It should be noted that the cross-link between the first and second studs 602a, 602b provides structural support for the -9 -through-hole to be created there between. Accordingly, in some examples, the first and second bridge portions 107, 109 are provided as separate pieces as shown in Figure 1. In some other examples, however, there is a support frame incorporating the first and second bridge portions 107, 109 such that they are connected to one another. Such a support frame may further enhance the structural support provided, and may also offer further fixation sites to fix to the first and second studs 602a, 602b.

[0047] While the support assembly may not comprise the first and second bridge portions as part of a support frame, the following description is in the context of the first and second bridge portions 107, 109 being connected to one another by the first and second side portions so as to form the support frame.

[0048] Accordingly, in some examples, the support assembly comprises a support frame, a plurality of filler pieces, and a plurality of boards. The support frame is configured to be fixed to studs of the stud wall via a first face of the stud wall. As described above, the first and second bridge portions 107, 109 have lengths which may be equal to, or similar to, an integer multiple of the outside-to-outside stud spacing. The lengths of the first and second bridge portions 107, 109 (including the respective first and second connection portions 107a, 107b, 109a, 109b) may be considered as a width of the support frame. That is because, in the in-use configuration, the first and second bridge portions 107, 109 form the top and bottom sides of the support frame.

[0049] Therefore, the support frame has a width dimension which meets the following two conditions. Firstly, a first section of the support frame overlaps a first stud of the stud wall when positioned on the first face of the stud wall. And, secondly, the width dimension is oriented perpendicular, or close to perpendicular, to a longitudinal axis of the studs vertically oriented, a second section of the support frame overlaps a second stud of the stud wall, the second section being positioned opposite to the first section along a width direction of the support frame. These two conditions in combination mean that the width is chosen in consideration of the stud spacing of the particular stud wall in question. In these examples, the "first section" includes the described first side portion, at least a part of the first connection portion 107a of the first bridge portion 107, and at least a part of the first connection portion 109a of the second bridge portion 109. In these examples, the "second section" includes the described second side portion, at least a part of the second connection portion 107b of the first bridge portion 107, and at least a part of the second connection portion 109b of the second bridge portion 109.

[0050] The filler pieces are for being positioned in cavities of the stud wall at a set of through-hole boundary faces, the set of through-hole boundary faces being created when the through-hole has been formed in a region of the wall surrounded, in use, by the support frame positioned on a first face of the stud wall. The plurality of boards configured to be fixed to the plurality of filler pieces and to cover up the set of through-hole boundary faces.

[0051] Figure 2 is a first simplified schematic front view of a support assembly 100, according to examples. The support assembly 100 is for providing structural support to a through-hole 808 to be formed in a stud wall 106. While examples of the support assembly 100 comprise the described plurality of boards, these are not shown in Figure 1 for simplicity (instead see Figure 12). The support assembly 100 comprises the support frame 102. In some examples, there may be more than one support frame.

[0052] The support frame 102 has a width Was indicated in the examples of Figure 2. The stud wall 106 comprises the studs 602. Only some of the studs 602 which may be present in the stud wall 106 are shown in Figure 2. All elements which are positioned behind other elements (for example, the studs 602) are indicated in dashed line.

[0053] Those skilled in the art will appreciate that the studs 602 of the stud wall 106 are vertically oriented relative to the ground/floor. The width W of the support frame 102 is oriented in perpendicular relation to the studs 602. In these examples, the first section 103 of the support frame 102 overlaps the first stud 602a, and the second section 105 of the support frame 102 overlaps the second stud 602b. For example, this occurs when the support frame 102 is positioned on the first face 104 of the stud wall 106, with the width W oriented perpendicular to the studs 602 and perpendicular to the ground/floor. Accordingly, the width W extends in a direction from/to the first and second sections 103, 105, which are on opposite sides of the support frame 102. In other words, the width W extends in a direction to/from the first and second studs 602a, 602b.

[0054] For example, the first section 103 comprises the side portion 111 and at least a part of the first connection portions 107a, 109a. For example, the second section 105 comprises the side portion 113 and at least a part of the second connection portions 107b, 109b.

[0055] The width dimension W of the support frame 102 is the dimension which has specifically been configured so that both the first and the second sections 103, 105 overlap wall studs 602 at the same time. Accordingly, the width W is chosen such that there is a dependence of the width W on the spacing between studs 602, of the particular stud wall 106 on which the support assembly 100 is to be deployed. It should be noted that different stud walls 106 may have different respective spacings between studs 602. For example, the width W may be equal to, or similar to, an integer multiple of the outside-to-outside stud spacing.

[0056] When the through-hole 808 is made in the stud wall 106, the wall panel(s) in the way of the through-hole 808 are cut. Also, any stud(s) which lie in the way of the through-hole 808 will be cut. In between the wall panels which define the opposing faces of the stud wall 106 at the boundaries of the through-hole 808, there will be either a stud 602 or cavity. In the examples of Figure 2, there are the filler pieces 108. For example, the filler pieces 108 comprise a structure and material to which fixings such as screws, bolts and the like can be applied. The filler pieces 108 may be fixed to the wall panels and/or the studs 602 using such fixings as may be suitable, as the case may be. In some examples, the filler pieces 108 comprise wood. Wood may be advantageous because wood may be sawn to the required sized to fit particular cavity spaces exposed by the making of the through-hole 808. In other examples, the filler pieces 108 may comprise steel. For example, galvanised steel may be used, which has enhanced corrosion resistance. For example, steel filler pieces may be in the form of box sections, or other structures which allow greater access in and around said structure for a fixing to be applied. For example, a fixing can be applied to an inner surface of a steel box section piece, which is not possible with a block of wood. Various examples are possible.

[0057] In these examples the support frame 102 forms a rectangle surrounding the area in which the through-hole 808 is to be made in the stud wall 106. In another example (not shown) the support frame 102 forms a shape other than a rectangle that surrounds the area in which the through-hole 808 is to be made in the stud wall 106. For example, first and side portions 111, 113 may form other shapes than the straight vertical pieces as shown in Figure2. Accordingly, the support frame 102 is not limited to a particular shape, but those skilled in the art will appreciate that shapes such as rectangular (of which, a square is a special case) may be preferrable due to ease of manufacture, for example. In some examples, the support frame 102 forms a rectangle surrounding the through-hole 808 to be made in the stud wall 106.

[0058] The through-hole 808 is to be formed in the stud wall 106 within the area bound by the support frame 102 once it is correctly located and fixed to the stud wall 106. In the examples of Figure 1, the through-hole 808 has already been formed.

[0059] In some of these examples the support frame 102 is a single, monolithic element, whereas in other examples, the support frame 102 comprises a plurality of support frame segments. In other words, in some examples, the support frame 102 comprises a plurality of support frame segments, configured to be assembled to provide the support frame 102. That is to say, the support frame 102 may be formed from a single segment or from two or more segments that fit together to form the support frame 102. In some examples (not shown) where the support frame 102 comprises two or more segments it may be desired to secure the segments together, for example using fixings such as bolts or screws. In these examples, it may be desired to secure the segments together using a bracket (not shown) to increase the rigidity of the support frame 102. For example, where the support frame 102 comprises horizontal segments and vertical segments arranged in perpendicular relation, these may be secured to one another using brackets. Figures 3 to 5 show various examples of support frame segment arrangements which could be used.

[0060] In some examples (see Figure 3), The first and second bridge portions are each provided as single monolithic pieces. And, the first and second side portions 111, 113 are also each provided as single monolithic pieces. In these examples, connections are made between the separate pieces using brackets 302 (not shown in Figures 4 and 5).

[0061] For example, the support frame segments may comprise two or more vertical pieces and two or more horizontal pieces. Providing the support frame 102 as a plurality of segments makes the support frame 102 easier to manufacture and to transport to the site of installation. In addition, the support frame 102 being comprised of a plurality of segments may also be easier to install.

[0062] In some examples, the support frame segments which define the width W of the support frame 102 (e.g., the segments intended to be installed in a horizontal fashion along the width direction W) may be configured such that any combination of such segments meets the condition of defining the width W to be equal to, or similar to, an integer multiple of the outside-to-outside stud spacing. In this manner, the support frame 102 may be assembled to span only one inter-stud space, or two inter-stud spaces (as in the examples of Figure 7), or three, and so on. In this way, there may be provided support frame segments from which can be assembled various widths of support frames, while still meeting the condition that the first and second sections 103, 105 align with studs 602 (whether those studs are adjacent or have a number of other studs therebetween).

[0063] Figure 6 is a simplified schematic internal front view of the stud wall 106, according to examples. The studs 602 of the stud wall 106 have a longitudinal axis L that extends along the length of each of the studs 602. Those skilled in the art will appreciate that the longitudinal axes L are intended to be parallel to one another. For example, the longitudinal axes L are also parallel to the faces of the stud wall 106. For example, the longitudinal axes L are also perpendicular to the floor upon which the studs 602 and the stud wall 106 are located. The studs 602 are located within the stud wall 106 and extend vertically upwards from the floor to which the studs 602 are secured. In other words, the studs 602 of the stud wall 106 extend vertically upwards from the base to the top of the stud wall 106. Accordingly, Figure 6 shows examples of the structure (not including the wall panels) onto which the support assembly 100 may be deployed.

[0064] Figure 7 is a simplified schematic internal front view of the support frame 102, according to examples. In Figure 7, wall panel(s) are omitted to show the studs 602 lying behind said wall panel(s). Figure 7 is intended to help describe how the support frame 102 is deployed, for example. It should be noted that in examples, the support frame 102 would be deployed onto the wall panel(s) which cover up the studs 602 that can be seen in Figure 7. In other words, the support frame 102 is intended to be fixed to the studs 602 via the wall panel(s). In other words, the support frame 102 is intended to be fixed to the studs 602 with the wall panel(s) being present between the support frame 102 and said studs 602. In other words, the support frame 102 may be deployed onto the stud wall 106 without removal of the wall panel(s). For example, a fixing which fixes the support frame 102 to the studs 602 passes first through the support frame 102, then through the wall panel(s), and finally into the relevant studs 602.

[0065] As previously described, the width dimension W of the support frame 102 is such that when the first section 103 of the support frame 102 overlaps the first stud 602a of the stud wall 106, and the width dimension W of the support frame 102 is orientated perpendicular, or close to perpendicular, to the longitudinal axis L of the studs 602, the second section 105 of the support frame 102 overlaps the second stud 602b of the stud wall 106. That is to say, when in situ on the stud wall 106, the support frame 102 spans at least two studs 602. In other words, when fixed to the stud wall 106, in the correct orientation (i.e., the width dimension W being perpendicular or close to perpendicular to a longitudinal axis L of the studs 602) the support frame 102 is fixed to at least two studs 602 of the stud wall 106.

[0066] Figure 8 is a simplified schematic front view of the support frame 102, according to examples. Both Figure 7 and Figure 8 show fixings 702 of the support frame 102 represented by an 'X'. In the examples of Figure 8, the first face 104 of the stud wall 106 (which would be made up of one or more wall panels) is shown. In the examples, the positioning of the fixings 702, i.e., the location of the 'X' symbol is purely for the sake of example and is not intended to portray exactly where such fixings 702 should be located on the support frame 102. Importantly, as can be seen from the examples of Figure 7, the fixings 702 are deployed at positions where there is overlap between the support frame 102 and one of the studs 602. For example, there are fixings 702 deployed to fix to the first and second studs 602a, 602b as may be expected from the above description, but also as the position of overlap with another of the studs 602 which is positioned between the first and second studs 602a, 602b.

[0067] The support frame 102 is configured to receive fixings 702 for fixing the support frame 102 to the studs 602 Put another way, the support frame 102 is configured to receive fixings 702 for fixing the support frame 102 to at least the first stud 602a and the second stud 602b. For example, the support frame 102, or at least parts thereof, are so configured by being composed of a material and of a thickness which may be punctured by fixings such as self-tapping screws and the like. In some examples, the support frame 102 comprises steel. In some examples, the thickness of the steel is between 0.5 millimetres and 3 millimetres.

[0068] The fixings 702 used to secure the support frame 102 to the stud wall 106 may be any suitable means for fixing the support frame 102 to the studs 602 (e.g., screws, bolts, self-tapping screws, and the like).

[0069] Having been secured to the stud wall 106 by fixings 702, the support frame 102 surrounds an area of the stud wall 106. In the examples where the support frame 102 defines a rectangular space within the support frame 102, a rectangular section of the stud wall 106 is surrounded by the support frame 102. The through-hole 808 may then be formed within the area bound by the support frame 102. The through-hole 808 may be formed by any suitable means (i e., any means suited to cutting through the faces 104, 1107 and studs 602 of the stud wall 106).

[0070] The size of the through-hole 808 may not be larger than the area of the stud wall 106 surrounded by the support frame 102. The through-hole 808 may extend to fill the majority of the area of the stud wall 106 surrounded by the support frame 102 as shown in Figure 8. In these examples, the though-hole 808 is the same shape as the support frame 102. That is to say, the support frame 102 is a rectangle and a rectangular through-hole 808 is formed in the area of the stud wall 106 bound by the support frame 102. Although one skilled in the art would understand that this configuration of through-hole 808 and support frame 102 will provide the stud wall 106 with the best integrity, the support assembly 100 of this invention is not so limited. For example, if it is preferred, the support frame 102 may form a rectangle that surrounds a though-hole 808 that is circular (not shown) or any other combination of shapes. One skilled in the art would understand that such a non-rectangular through-hole may be preferred for aesthetic reasons, or perhaps to fit around a specific unit (i.e., a duct, ventilation shaft, cable etc.) that is to be located within the through-hole 808 once it has been formed. Various examples are possible.

[0071] In some examples, the first and second bridge portions 107, 109 comprise a plurality of holes configured to receive fixings for fixing the support frame to at least the first and second studs. In addition, the first and second side portions 111, 113 may also comprise some of said plurality of holes. In some such examples, the support frame 102 comprises a plurality of holes configured to receive fixings for fixing the support frame 102 to at least the first and second studs 602a, 602b. Figure 9 is a simplified schematic perspective view of a portion of the support frame 102, according to examples. The portion shown in Figure 9 may also be considered as one of the above-described support frame segments 902 As a mere example, the segment 902 of figure 9 may be the first bridge portion 107. In these examples, the support frame segment 902 has a thickness dimension t. The thickness dimension t being perpendicular to the width dimension W of the support frame 102.

[0072] In these examples, the support frame 102 also comprises the plurality of holes 910, an example of these holes 910 can be seen formed in the support frame segment 902 in Figures 9 and 10. The plurality of the holes 910 extend through the thickness t of the support frame segment 902 (and hence also extend through the thickness of the support frame 102). The holes 910 are configured to receive the fixings 702. In the examples at least some of the plurality of through holes 910 are slotted holes (in other words, not circular but elongate). In other examples (not shown) the through holes 910 may be any shape suitable for receiving a fixing means. While the through holes 910 made in the support frame 102 are described here in the context of the support frame segment 902, it should be noted that the through holes 910 are not limited to examples where the support frame 102 is in the form of a plurality of support frame segments 902 to be assembled. In other words, the through holes 910 may also be provided in examples where the support frame 102 is a single, monolithic article.

[0073] In the examples described thus far, the support frame 102 is shown to have a flat profile.

However, the present disclosure is not so limited. Figure 10 is a second simplified schematic perspective view of a portion of the support frame 102, according to examples. Reference is again here made to the support frame segment 902, which is shown in Figure 10 according to a different example, as compared to Figure 9.

[0074] In some examples, each of the first and second bridge portions comprises: a first planar section; and a second planar section configured at a non-zero angle relative to the first planar section. In some such examples, the first and second side portions 111, 113 may also comprise respective first and second planar sections. In the context of the support frame 102 as a whole, the support frame 102 comprises a first planar section 906 and a second planar section 908. The second planar section 908 of the support frame 102 is configured at a non-zero angle relative to the first planar section 906 of the support frame 102. In some of the examples, the non-zero angle between the first planar section 906 and the second planar section 908 of the support frame 102 is such that the first planar section 906 is perpendicular to the second planar section 908.

[0075] In other examples, the non-zero angle between the first planar section 906 and the second planar section 908 is less than 90°. In other examples, the non-zero angle between the first planar section 906 and the second planar section 908 is greater than 90°. In these examples, a first surface of the first planar section 906 is configured to face the first face 104 of the stud wall 106 (this orientation is shown in Figures 11 and 12). The first surface of the first planar section 906 may be referred to as the frame contact surface.

[0076] In another example (not shown), the support frame 102 may comprise three planar sections, for example in the form of a channel such as a U-channel, a C-channel and the like. In such examples, the backside of the web (which may act as the first planar section) of the channel may form the frame contact surface. In some other examples (not shown), the support frame 102 may comprise box sections.

[0077] Figure 11 is a first simplified schematic partial perspective view of the through-hole 808, according to examples. In these examples, the support assembly 100 comprises a plurality of filler pieces 108. The filler pieces 108 are positioned after the through-hole 808 has been created. As a consequence of the through-hole 808 being created, there are also created through-hole boundary faces 904, as indicated in Figure 11.

[0078] In some examples, the set of boundary faces 904 are at a non-zero angle to the stud wall 106. In some examples the set of boundary faces 904 are perpendicular or near to perpendicular relative to the stud wall 106. It will be appreciated that this may depend on how the through-hole 808 is cut.

[0079] Figure 12 is a second simplified schematic partial perspective view of the through-hole 808, according to examples. In these examples, the support assembly 100 is shown together with some of the plurality of boards 1000. The plurality of boards 1000 are configured to be fixed to the plurality of filler pieces 108. For example, the filler pieces 108 provide attachment sites for the boards 1000 to be fixed, where there would otherwise just be cavities. In this manner, the boards 1000 are provided with structural support from the filler pieces 108. The plurality of boards 1000 are configured to cover up the set of through-hole boundary faces 904. In some examples the boards 1000 are fire retardant. For example, the boards 1000 may be formed from fire retardant material such as Gypsum based plasterboard, calcium silicate board, cement board, MDF (medium-density fibreboard), mineral wool fire batt or products that are configured from a combination of these materials. For example, the boards 1000 may be coated in a fire retardant substances such as intumescent or fire retardant paint, paste or spray.

[0080] The examples of the support frame 102 which are shown in Figures 11 and 12 are the examples which comprise the described first and second planar sections 906, 908 arranged at an angle relative to one another. Also, in the examples of Figures 11 and 12, the through-hole 808 is made so as to be directly adjacent to the support frame 102, and therefore is of the maximum size as allowed by the support frame 102 surrounding the through-hole 808. The relative angle between the first and second planar section 906, 908 may be advantageous in that it improves the robustness of the support frame 102 In addition, such an arrangement may also be useful for installing additional components onto, or with respect to, the support frame 102, as described in the examples below.

[0081] Figure 13 is a first simplified cross-sectional view of the support assembly 100 deployed to the through-hole 808, according to examples. Figure 14 is a second simplified cross-sectional view of the support assembly 100 deployed to the through-hole 808, according to examples. Figure 15 is a third simplified cross-sectional view of the support assembly 100 deployed to the through-hole 808, according to examples. Figure 16 is a fourth simplified cross-sectional view of the support assembly 100 deployed to the through-hole 808, according to examples. In these examples, there can be seen a first wall panel 1103 which forms the first face 104 of the stud wall 106, and a second wall panel 1105, which forms a second face 1107 of the stud wall 106. The second face 1107 of the stud wall 106 face out in the opposite direction to the first face 104. Fixings which fix the support frame 102 to the studs 602 are not shown for simplicity.

[0082] In some examples, such as those of Figures 13 to 16, the support assembly 100 comprises a set of fire-retardant battens 1102. The fire-retardant battens 1102 are configured to cover the exposed surfaces of the support frame 102. More specifically, the fire-retardant battens 1102 are configured to cover at least some of the surface of the support frame 102 other than the first surface of the first planar section 906 that is fixed directly onto the face 104 the stud wall 106.

In some examples the fire-retardant battens 1102 are configured to cover the majority of the surface of the support frame 102 other than the first surface of the first planar section 906 and other that the edge surfaces which are defined by the thickness t of the support frame 102.

[0083] In the examples of Figure 13, the support frame 102 has a flat profile. The fire-retardant battens 1102 are simply positioned to cover up a face of the support assembly 100 which faces away from the first face 104 of the stud wall 106. In the examples of Figure 14, the support frame 102 comprises the first and second planar sections 906, 908 perpendicular to one another. In these examples, each side of the support frame 102 is provided with a pair of the fire-retardant battens 1102. For example, there is arranged a batten 1102 on either side of the second planar section 908. For example, the battens 1102 may be configured such that they sit flush to one another, and the batten 1102 further away from the through-hole 808 in these examples sits flush against the first surface 104 as shown.

[0084] In some examples, the support assembly 100 comprises a third bridge portion and a fourth bridge portion, the third and fourth bridge portions each configured to be fixed to studs of the stud wall via a second face of the stud wall opposite the first face. In these examples, each of the third and fourth bridge portion: is elongate and comprises a first connection portion and a second connection portion such that when the first connection portion overlaps the first stud, in an in-use position and orientation on the second face, the second connection portion overlaps the second stud. The third and fourth bridge portions may have any combination of the features described in relation to the first and second bridge portions. In some examples, the third and fourth bridge segments are identical to their counterpart first and second bridge portions.

[0085] For example, the support assembly 100 may comprise more than one support frame 102. For example, as in the examples of Figures 15 and 16, there may be a first support frame 102a and a second support frame 102b. For example, the first support frame 102a may be deployed onto the first surface 104 of the stud wall 106, and the second support frame 102b may be deployed, in a corresponding position, on the second face 1107 of the stud wall 106. In these examples, the first support frame 102a and the second support frame 102b may be fixed together through the stud wall 106 using long fixings, for example screws or nuts and bolts (not shown). The long fixings may be used in addition to the fixings 702 configured to secure the support frame 102 to the studs 602 as already described. The two support frames 102a, 102b may have any combination of the features described in relation the support frame 102 generally. In some examples, the first and second support frames 102a, 102b are identical to one another. In other examples, the first and second support frames 102a, 1026 may have differing features, so long as they are both dimensioned appropriately to be installed at opposing sides onto the studs 602. Figure 15 shows examples in which both the first and second support frames 102a, 1026 have a flat profile. On the other hand, Figure 16 shows examples in which the first and second support frames 102a, 102b have the described first and second planar sections 906, 908.

[0086] In examples, the support frame 102 is comprised of any suitably strong material such as metal. In some examples, the support frame 102 is comprised of steel. In some examples, the support frame 102 is comprised of galvanised steel.

[0087] There may be provided a method for providing structural support for a through-hole 808 to be formed in a stud wall 106 by deploying a support assembly 100 according to any of the described examples.

[0088] In some examples, the support assembly 100 comprises a firsft bridge portion 107 and a second bridge portion 109 (e.g., in the form of a support frame 102) configured to be fixed to the stud wall 106 via a first face 104 of the stud wall 106.

[0089] The support assembly 100 further comprises a plurality of boards 1000 configured to be fixed to the plurality of filler pieces 108 and to cover up the set of through-hole boundary faces 904.

[0090] The method may further comprise fixing the first connection portion 107a of the first bridge portion 107 and the first connection portion 109a of the second bridge portion 109 to the first stud 602a through a wall panel forming the first face 104 of the stud wall 106, and fixing the second connection portion 107b of the first bridge portion 107 and the second connection portion 109b of the second bridge portion 109 to the second stud 602b through the wall panel forming the first face 104 of the stud wall 106 prior to forming the through-hole 808 in the stud wall 106. The through-hole 808 may then be formed in the region of the stud wall 106 delimited by the first and second bridge portions 107, 109. After forming the through-hole 808 within an area of the first face 104 of the stud wall 106 delimited by the bridge portions, for example, bound by the support frame 102, the through-hole 808 has a size smaller than the area of the first face 104 of the stud wall 106 bound by the support frame 102.

[0091] In some examples, the method comprises positioning and securing the filler pieces 108 in the cavities of the stud wall 106 at the set of through-hole boundary faces 904.

[0092] In some examples, the method comprises fixing the plurality of boards 1000 to the filler pieces 108 to cover up the set of through-hole boundary faces 904.
