Field
[0001] The present invention relates to door fixing arrangements. More particularly, the present invention relates to door fixing arrangements that reduce the presence of gaps between a door and a wall to which the door is mounted to avoid the need to provide fire-proof cladding in between a door and the wall to which it is mounted.
Background
[0002] As shown in Figure 1, in a typical building construction 100, doors 110 need to be mounted within walls 120 (the walls typically made of masonry or stud and plasterboard, but in the example shown the wall is made from metal stud and plasterboard). In Figure 2, there is shown that the structure 200 of a typical building provides a wooden frame into which the door 110 can be mounted and on to which the walls 120 can be fixed. Such an arrangement 200 would include door lining fixings 210 (on to which a door 110 can be mounted) and other structural fixings such as head fixing brackets 230 and jamb fixing brackets 220.
[0003] To fix a door 110 to a door lining 210, a known door hinge and mounting bracket arrangement 300 is shown in Figure 3 and will now be described in more detail below.
[0004] A door 310 is mounted to hinge 320 using screws (not shown) provided through one plate of the hinge 320 into the door 310. The second plate of the hinge 320 is attached to a timber door lining 340 using a screw 335 which is fixed through the timber door lining 340, some non-combustible packers 370 a metal partition stud 370 and into a wood fixing portion 380.
[0005] Further screws 335 may be provided to fix the timber door lining 340 through the non-combustible packers 370, the metal partition stud 370 to the wood fixing portion 380. A stop 330 is typically provided adjacent to the door 310 and also fixed to the timber door lining 340. Further, to hide the edge of the plasterboard 360 where the wall meets the door, architrave 350 (usually made from materials such as timber or MDF) is provided to cover the wall-facing sides of the timber door lining 340 and the edges of the plasterboard 360 that are adjacent to the timber door lining 340. Further metal partition studs 370 are provided along the wall.
[0006] One problem with the arrangement shown in Figure 3 is the need to gain fire certification for the design and combination of materials used in the design. Specifically, the choice of non-combustible packers in combination with the design and materials of the other components and parts of the door frame arrangement need to be certified together in combination. If alternative designs are required, or different materials used (for example, for the non-combustible packers), then re-certification is required before the design and materials chosen can be used.
Summary of Invention
[0007] Aspects and/or embodiments seek to provide an adjustable fixing bracket for fixing linings to walls or partitions and specifically a bracket that can remove the need for using non-combustible packers when fixing doors to door linings in construction.
[0008] According to a first aspect, there is provided a mounting bracket for a wall comprising an end portion and a pair of side portions, wherein: the end portion comprises at least one substantially flat plate having a plurality of fixing points, each fixing point for receiving a fastening member; the side portions each comprising at least one substantially flat plate and at least one fixing point, each fixing point for receiving a fastening member, and the side portions formed substantially perpendicular to the end portion and each side portion being substantially parallel to the other side portion.
[0009] By providing a single mounting bracket able to be fixed along both the end portion and the side portions, the mounting bracket of this aspect and/or embodiments can be adjusted at any point during installation, as the fixings are only covered at plastering or tacking stages of construction.
[0010] By providing a single mounting bracket able to be fixed along both the end portion and the side portions, this bracket can require no further packing materials, thus needing no testing in line with mixing various fire products and the resultant suitability when acting together with such packing materials. Additionally, as no further packing can be required to secure the lining, it follows that no further fire products are required to protect the packing materials.
[0011] Optionally, the end portion is operable to be mounted to a door lining. Optionally, the side portions are operable to be mounted to one or more metal stud partitions.
[0012] As fixing points for fastening members are provided in the bracket in the end portion and the side portions, the bracket can require no predetermined stud locations to be fixed in place and can work in substantially any manufacturer setup approved detailing. Specific configurations of holes for fastening members can be provided in different embodiments of the bracket, or self-drilling screws can be used at the fixing points and no holes need be provided in the end and/or side portions.
[0013] Optionally, the side portions are operable to allow fixing to the door lining and plasterboard to be mounted to the wall without some components of the wall or door lining preventing installation of other components of the wall or door lining.
[0014] Plasterboard can be mounted to the wall and the side portions can be fixed to the door lining without clashes between components of the wall and/or door lining. Clashes occur when components installed by one type of trade prevent other components being installed by another type of trade, and it is therefore preferred to avoid clashes if possible.
[0015] Optionally, the side portions are formed with the end portion to provide a plurality of lips on the end portion. Optionally, the side portions meet the end portion substantially away from the edge of the end portion to form the plurality of lips on the end portion.
[0016] By forming the bracket in a T-shape for each of the side portions, the end portion is formed having lips on one side of each join with each side portion, forming two lips.
[0017] Optionally, the plurality of lips comprises at least one of the plurality of fixing points for receiving a fastening member. Optionally, each of the plurality of lips comprises at least one of the plurality of fixing points for receiving a fastening member.
[0018] By providing lips, fixing can be more easily achieved when installing the bracket as the fixing points are accessible from the surface of the bracket that is exposed during installation. One of the lips can be used for fixing, or both lips can be used for fixing the bracket.
[0019] Optionally, the side portions each comprise a plurality of fixing points, each fixing point for receiving a fastening member.
[0020] Metal stud partitions in construction require multiple fixing points within approved details as fixing into the jamb stud alone is not suitable within metal partition systems due to the resultant twist and movement in differing materials. By providing multiple fixing points in the bracket, multiple fixing points can be provided when installing the bracket.
[0022] The fixing points can be provided as holes into which screws and/or other fasteners can be received.

Specific Description
[0024] Referring to Figures 4 to 7, an embodiment of door mounting arrangement will now be described below in more detail. Aspects and/or embodiments provide an adjustable fixing bracket used for fixing linings to wall or partitions.
[0026] The bracket 400 is a T-shaped framing member which allows the fixing of linings to walls or partitions with a substantially high degree of accuracy as typically needed in construction detailing, including fire details and minimal gap requirements in accordance with manufacturer guidelines.
[0027] The bracket 400 is provided having an end portion 430 and two side portions 410, each side portion 410 in the T-shaped arrangement with the end portion 430. The configuration of the portions is such that the two side portions 410 extend perpendicular from the end portion and parallel to each other.
[0028] The end portion 430 and the two side portions 410 are all flat plates, in this embodiment made from metal, formed by welding the plates together. In other embodiments, alternative materials can be used. In other embodiments, the part may be formed by casting or other process and formed as a single part.
[0029] Referring next to Figure 5, there is shown the face of the end portion 500 of the bracket of Figure 4 which will now be described in more detail below.
[0030] The end face 510 (of the end portion 430) is provided with screw holes 520 at either side of the face 510, for mounting when installed.
[0031] Referring now to Figure 6, there is shown a bracket side portion face 600 according to an embodiment which will now be described in more detail.
[0032] The side face 610 (of each of the side portions 410) has at least one screw hole 620 provided along its face, for mounting when installed.
[0033] Referring now to Figure 7, there is shown a cross-section view of a door hinge and mounting bracket arrangement 700 according to an embodiment which will now be described in more detail below. In this embodiment, the wall construction uses stud partitions.
[0034] In this embodiment, a door 710 is mounted to a hinge 720. The hinge 720 is provided having two hinge plates able to move relative to each other around an axis defined where the two plates are joined. One hinge plate is mounted to the door 710 using screws (not shown). The other hinge plate is mounted to one side of the timber door lining 740.
[0035] The bracket 730 is mounted to the other side of the timber door lining 740 using screws 760a. The bracket 730 is also mounted to two metal partition studs 770 at two positions along the wall using screws 760b, 760c on each side of the wall.
[0036] In alternative embodiments, where the bracket is used with a solid wall, the bracket 730 can be attached to the solid wall at various positions as appropriate instead of to the metal stud partitions and/or any wood fixing 790.
[0037] The timber door lining can also have a stop 735 mounted on it adjacent to the door 710 and an architrave 750 to cover the side of the timber door lining 740 and the edge of the plasterboard 780.
[0038] The fixing bracket 730 is fixed to the lining 740 prior to installation to the wall or partition by screws. When fixing to solid walls, the bracket 730 can be fixed at any suitable location along the long legs (i.e. side portions 410) of the bracket 730. When fixing to stud partitions, the bracket 730 is fixed via the predrilled holes (i.e. screw holes 620) along the legs to the timber 790 within the jamb lining, the bracket can then be screwed through at any location to the next stud 770 for rigidity, using self-drilling screws into metal, or timber screws into timber. The bracket 730 of this embodiment thus requires no predetermined stud locations to be fixed in place and will work in substantially any manufacturer setup approved detailing.
[0039] In this embodiment, the fixing can be adjusted at any point during installation, as the fixings are only covered at the plastering or tacking stages of construction.
[0040] The bracket 730 can also require no further packing materials, thus not need (fire safety) testing and/or certification of mixed fire products and the resultant suitability when acting together. As the bracket 730 does not need further packing to secure the lining, this can mean that no further fire products are required to protect packing material.
[0041] Furthermore, the increased use of metal stud partitions in construction requires multiple fixing points within approved details, as fixing into the jamb stud alone is not suitable within metal partition systems due to the resultant twist and movement in differing materials, so this bracket 730 can allow multiple fixing points when stud partitions are used.
[0042] In embodiments, the fixing bracket 730 can be manufactured at various typical wall or partition sizes and yet remain the same in fixing and design detailing, whether fixing the jamb or head of the lining to partitions or walls.
[0043] Any system feature as described herein may also be provided as a method feature, and vice versa. As used herein, means plus function features may be expressed alternatively in terms of their corresponding structure.
[0044] Any feature in one aspect may be applied to other aspects, in any appropriate combination. In particular, method aspects may be applied to system aspects, and vice versa. Furthermore, any, some and/or all features in one aspect can be applied to any, some and/or all features in any other aspect, in any appropriate combination.
