Description

The present invention relates to structural elements and building materials. In particular, the present invention relates to load bearing structural elements. During the construction of a building, it is important to support the wall above an opening such as a door or window opening otherwise the stability and structural integrity of the building may be compromised. Typically, a lintel is used to support the wall above the opening. A lintel is an elongate structure which transfers the weight of the wall directly above the opening to the parts of the wall at either side of the opening. It is also typical to install a damp proof course to the building during construction, particularly where the building has a cavity wall having an inner leaf, an outer leaf and a cavity therebetween. The use of a damp proof course prevents the ingress of moisture within the cavity and thereby prevents damp problems developing within the property. One example of a damp proof course are cavity trays which are typically installed above openings in the building such as above doors and windows. It is therefore required to install the damp proof course around a lintel. This can be time consuming and complex and can therefore often result in improper installation of the cavity tray and / or the lintel. A further problem with associated with building components, such as cavity trays and structural supports, in the cavity of a cavity wall is that moisture on the building components may cascade over the ends of the building components, into the cavity. Overtime, this ingress of moisture in the cavity may result in internal dampness within the building. In order to avoid this problem, a stop end may be installed at the ends of structural supports such as lintels. The addition of the stop end adds further complexity and risk to the integrity of the cavity tray and structural support such as a lintel. It is therefore advantageous to overcome the problem of fitting the damp proof course, stop end and lintel around one another. Attempts have been made to overcome this problem by forming combined lintel and cavity tray products. However, these current products are bulky, modular products and therefore must be supported by both leaves of the cavity wall which requires fixing the product around insulation, fire barriers and other building components within the cavity. Furthermore, these current products either do not comprise a stop end or the stop end is formed as a separate modular part. Therefore, assembly of these products is still complicated and require further consideration onsite. This may also result in installation of the stop ends being forgotten or being improper. It would therefore be advantageous to mechanically fix the stop ends to building components in a factory environment However, a problem with fixing stop ends to building components in the factory is that the stop ends must align with a perp joint between adjacent bricks of a wall above an opening over which the building component is to be installed. In addition, the building component must extend beyond both sides of the opening by an adequate length to enable stability of the building component and the building. Therefore, complexities may arise during installation as the design around an opening in a wall is not always formed perfectly. Often, half brick bonds are required around the opening in the wall and the building component must be moved laterally to one side more than the other to ensure that the building component is properly supported and to align the stop ends within a perp joint. If moving the building component does not allow the building component to rest an adequate distance away from both sides of the opening, then a new building component much be purchased and / or fabricated. With multiple openings in each building, this can be costly, time consuming and frustrating for onsite operators and consumers. Furthermore, this can result in stop ends being damaged or forced into position such that the integrity of the stop ends is compromised. It is therefore an object of the present invention to overcome the above-mentioned problems. It is also an object of the present invention to improve the ease of installation of lintels and cavity trays in a building construction. According to a first aspect of the invention there is provided a structural support comprising a load bearing means, a means for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall of a building and one or more stop ends wherein the one or more stop ends are mechanically fixed to the load bearing means.

However, the skilled person would be aware that where the brickwork bond to be installed above the structural support and / or on the load bearing means of the structural support and / or base the structural support / load bearing means would result in the distance between adjacent perp ends being less than that of a stretcher bond, then the compensating length required will be less than that required when a stretcher bond is to be installed. For example, the compensating length will be less when the brickwork bond to be installed above the structural support and / or on the load bearing means of the structural support and / or base of the structural support / load bearing means is a header bond.

Figure 11 is a perspective view of a means for draining internal moisture to the externa surface of a cavity wall according to another embodiment of the present invention. In the drawings there is provided a structural support indicated generally by reference numeral 1 having a load bearing arrangement 2, an arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall of a building 3 and a stop end 4 wherein the stop end 4 is mechanically fixed to the load bearing arrangement 2. Fixing the stop end 4 to the load bearing arrangement 2 improves the ease of installation of the structural support 1 and also prevents disengagement of the stop end with the load bearing arrangement 2. The structural support 1 is locatable above an opening 5 in a building construction such as a door or window opening, as illustrated in figure 1. The structural support 1 is configured to distribute the weight of the wall above an opening 5 to parts of the wall at each side of the opening 18, 19. The load bearing arrangement 2 is configured to distribute the weight of the wall above an opening 5 to parts of the wall at each side of the opening 18, 19. This prevents the opening 5 from collapsing and thereby improves the structural integrity of the building. The structural support 1 has a base 10 for supporting masonry thereon such as bricks 20. The base 10 forms part of the load bearing arrangement 2. The structural support 1 is configured to be positioned upon all / multiple reveals and / or brickwork bonds of an opening 5 above which the structural support 1 is to be supported so that at least the minimum bearing length and / or recommended bearing length of the structural support 1 is supported on each side 18, 19 of the opening 5 in the wall and so that the stop end 4 is in alignment with a perp joint 21 (see figure 6 and 7). The structural support 1 is sized to enable movement of the structural support 1 to left 19 and / or right 18 of an opening to ensure that the stop end / plurality of stop ends 4 are in alignment with a perp joint 21 between the masonry component / brick course directly above the base 10 of the structural support without the length of the structural support 1 supported on each side of the opening 5 being less than at least the minimum bearing length and / or recommended bearing length. Referring to figures 3, 6 and 7, adjacent stop ends 4 are fixed to the structural support 1 at a position wherein the distance between adjacent stop ends 4 corresponds to the length of a predetermined number of bricks 20 to be installed on the base 10 of the structural support 1 between adjacent stop ends 4. The one or more stop ends 4 are fixed to the structural support 1 at a position wherein the distance between adjacent stop ends 4 is predetermined by the type of bond of the masonry components / bricks to be installed above the base 10 of the structural support 1 / above the opening 5, 5A. The structural support 1 is sized to ensure that at least the minimum bearing length and / or recommended bearing length of the structural support 1 is supported on each side 18, 19 of the opening after the structural support 1 has been moved left 19 or right 18, depending on the reveal and / or brickwork bond below the structural support 1, to ensure that the one or more stop ends 4 are in alignment with a perp joint 21. The structural support 1 is sized to enable movement of the structural support 1 to the left 19 and / or right 18 of an opening to ensure that the stop end or stop ends 4 are in alignment with a perp joint 21 between the masonry component / brick course directly above the base 10 of the structural support 1 while also maintaining at least the minimum bearing length and / or recommended bearing length of the structural support 1 supported on both sides of the opening 5. This means that multiple structural supports will not be required to accommodate different reveals and / or brickwork bonds upon which the structural support is to be supported, of multiple openings which have the same dimensions. This also means that lateral movement of the structural support 1 will not compromise the integrity of the structural support 1 and / or the of the stop end or stop ends 4. This also means that lateral movement of the structural support to each side 18, 19 of the opening 5 will not result in less than the minimum bearing length and / or recommended bearing length of the structural support 1 being supported on each side 18, 19 of the opening 5. Referring to figures 6 and 7, the length A, B of the structural support 1 is sized to be positioned upon all / multiple reveals and / or brickwork bonds of an opening 5 above which the structural support 1 is to be supported and to ensure that at least 30mm of the structural support 1 is supported on each side 18, 19 of the opening 5. In this embodiment, at least 150mm of the structural support 1 is supported on each side 18, 19 of the opening 5. The structural support 1 is sized depending on the dimensions of the opening 5 above which the structural support 1 is to be supported plus the minimum bearing length and / or recommended bearing length plus a compensating length. By compensating length, we mean the additional length that is required to allow the structural support 1 to still be supported on each side 18, 19 of the opening by at least the minimum bearing length and / or recommended bearing length after the structural support 1 has been moved left 19 or right 18 to align the one or more stop ends 4 with a perp joint 21. As illustrated in figures 6 and 7, the structural support 1 can be used for openings, 5 and 5A, having the same dimensions regardless of the brickwork bonds upon which the structural support is to be supported, at the openings 5, 5A. This means that the type of structural support 1 required can be specified based on the length X, Y of the opening and the type of bond that is to be used immediately above the structural support only, without needing to specify the brickwork bond upon which the structural support 1 will be supported, saving time and costs. This is in comparison to structural supports which are custom built based on the brickwork bonds immediately below the structural support 1 which may differ for each opening of a building construction. This is further in comparison to structural supports with mechanically fixed stop ends where the structural supports are fabricated as standard, without taking account of the position of the mechanically fixed stop ends and / or the brickwork bond below the structural support and / or the dimensions of the opening such that, in use, the mechanically fixed stop ends do not align with perp joints of a wall or such that at least the minimum bearing length and / or recommended bearing length of the structural support is not supported on each side of the opening. This means that the structural support 1 can be moved further to the left of opening 5A, in relation to its position above opening 5, to accommodate for the half brick 41 reveal / bond at the left of the opening so that the structural support 1 is supported on both sides of the opening by at least the minimum bearing length required and / or recommended bearing length and to ensure that both of the stop ends 4 are in alignment with a perp joint 21 (see figures 6 and 7). The compensating length will depend on the type of brickwork bond to be installed above the structural support 1 and / or on the load bearing arrangement 2 of the structural support 1 and / or base 10 and / or above the opening 5, 5A. The compensating length corresponds to the maximum distance over which the structural support 1 would be required to move, to the left 19 or right 18 of the opening 5, 5A, to align the one or more stop ends 4 with a perp joint 21. Referring to figure 6, the compensating length corresponds to up to half of the horizontal measurement H of a surface F of one of the masonry components / bricks that will form the external surface of the outer leaf 6, that are to be installed above and / or below the structural support 1 and / or on the load bearing arrangement 2 of the structural support and / or base 10 and / or above the opening 5, 5A. Referring to figure 3, the structural support 1 is elongate having two longitudinal sides 23, 24 and two end sides 25, 26 extending between the longitudinal sides 23, 24. The structural support 1 has a left end side 25 and a right end side 26. The structural support 1 is configured to be positioned such that, in use, the left end side 25 extends at least 150mm beyond the left side 19 of the opening 5, 5A (see figure 6 and 7) and such that, in use, the right end side 26 extends at least 150mm beyond the right side 18 of the opening 5, 5A. The structural support 1 is configured to be positioned such that, in use, at least 150mm of the left end side 25 of the structural support 1 is supported on brickwork that is laterally disposed to the left side 19 of the opening 5, 5A and such that, in use, at least 150mm of the right end side 26 of the structural support 1 is supported on brickwork that is laterally disposed to the right side 18 of the opening 5, 5A. In the embodiment illustrated in figures 6 and 7, the compensating length is between 56mm and 225mm. However, when the brickwork bond to be installed above the structural support and / or on the load bearing means of the structural support and / or base of the structural support / load bearing means is a stretcher bond, as illustrated in figures 6 and 7, the compensating length is preferably between 56mm and 113mm. In this embodiment, one or both sides of the structural support 1 are sized to be approximately 206mm to 263mm longer than the length X, Y of the opening 5, 5A. Table 1 shows exemplary dimensions for a structural support 1 according to the present invention based on brickwork opening dimensions above which the structural support is to be supported. Table 1: Exemplary dimensions for a structural support based on brickwork opening dimensions. Brickwork Opening (mm) Structural Support Length (mm) 1810 2335 1922 2335 2035 2560 2147 2560 2260 2785 2372 2785 2485 3010 2597 3010 2710 3235 2822 3235 The structural support 1 is configured for use over any brickwork coursing and / or pattern including but not limited to stretcher, header, soldier, sailor, rowlock, shiner and / or any other suitable coursing and / or pattern. Figure 6 illustrates a structural support 1 having a length A that can be positioned over all / multiple brickwork bonds of an opening. Figure 6 illustrates a structural support 1 positioned over opening 5 and 5A. Opening 5 and opening 5A having the same dimensions and have a length X. The structural support 1 can be positioned over opening 5, supported on reveals and / or brickwork bonds by / having full bricks 40. The same structural support 1 can also be positioned over opening 5A, supported on reveals and / or brickwork bonds by / having half bricks 41. The same structural support 1 can also be positioned over opening (not shown), supported on reveals and / or brickwork bonds by / having a mixture of full and half bricks. This means that the structural support 1 can be moved to the left or right of the opening to align each of the stop ends 4 with a perp joint 1 and still be supported on both sides of the opening by the minimum bearing length required and / or recommended bearing length, regardless off the brick work bond upon which the structural support is to be supported. This means that the structural support 1 can be used over both openings 5, 5A and the stop ends 4 of the structural support 1 will be in alignment with a perp joint 21 and the structural support will be supported on both sides of the opening by at least the minimum bearing length and / or recommended bearing length required even if the structural support 1 needs to be moved to left or right of the opening to accommodate for the reveal and / or brickwork bond, of each opening, upon which the structural support is to be supported. This also means that if a building has both openings 5 and 5A, which have the same dimensions but the reveals and / or brick work bonds upon which the structural support is to be supported at each of the openings is different, then the consumer will only be required to specify and / or order one type of structural support 1 based only on the length / size of the openings 5, 5A and on the type of brickwork bond to be used above the structural support 1, without needing to predict the reveals and / or brickwork bonds immediately below the structural support, at each these openings and without risking improper installation of stop ends. Therefore, this saves time and cost, improves the integrity of the stop ends and improves the ease of installation of structural supports having mechanically fixed stop ends. The structural support 1 above opening 5 has been moved to the right of the opening 5, in relation to the position of the structural support 1 above opening 5A, to align the stop ends 4 with perp joints 21. After movement of the structural support 5 to the right, the structural support is still supported on the left side 19 by at least the minimum bearing length and / or recommended bearing length and is supported on the right side 18 by at least the minimum bearing length and / or recommended bearing length plus at least part of the compensating length. Figure 7 illustrates a structural support 1 having a length B that can be positioned over all / multiple brickwork bonds of an opening. Figure 7 illustrates a structural support 1 positioned over opening 5 and 5A. Opening 5 and opening 5A having the same dimensions and have a length Y. The structural support 1 can be positioned over opening 5 and 5A, supported on reveals and / or brickwork bonds by / having a full brick 40 on one side of the opening and a half brick 41 on the other side of the opening and vice versa._This means that the structural support 1 can be moved to the left or right of the opening to align each of the stop ends 4 with a perp joint 21 and still be supported on both sides of the opening by at least the minimum bearing length required and / or recommended bearing length, regardless off the brick work bond upon which the structural support is to be supported, at the opening. In this embodiment, the stop end 4 is a non-combustible stop end. This means in the event of a fire the stop end 4 will not burn and will not release flammable vapours which contribute to combustion. The stop end 4 is formed from steel. The stop end 4 is formed from stainless steel. The stop end 4 is locatable between masonry components on the outer leaf 6 of a cavity wall. The stop end 4 is locatable between adjacent bricks of a wall. The stop end 4 is locatable in the perp joint between masonry components of a wall. The stop end 4 is formed from the same material as the load bearing arrangement 2. However, the stop end 4 and the load bearing arrangement 2 may be formed from different materials. The stop end 4 is riveted, welded, spot welded, tack welded or mechanically fixed to the load bearing arrangement 2 by any other suitable means. The stop end 4 may be formed as a folded portion of the load bearing arrangement 2. This prevents moisture making its way underneath the corner of the load bearing arrangement 2 and backward into the window / door below the load bearing arrangement 2. The stop end 4 is configurable to prevent moisture cascading over an end of the structural support 1 in the cavity of the cavity wall. The stop end 4 is configurable to maintain internal moisture on the load bearing arrangement 2 so that it can be drained to the external surface of the outer leaf 6 of the cavity wall via a weep or other draining arrangement. The structural support 1 is configurable to extend into the cavity of a cavity wall. The structural support 1 is configurable to extend into the cavity from the outer leaf 6 of a cavity wall. The structural support 1 is not fixed to the inner leaf 7 of a cavity wall and is not installed between masonry components / bricks of the inner leaf. The structural support 1 is not supported by the inner leaf 7 of a cavity wall. In use, the structural support 1 does not contact the inner leaf 7 of the cavity wall. The structural support 1 is only fixed and / or installed between masonry components of the outer leaf 6 of the cavity wall at both sides 18, 19 of the opening 5 in the building and / or between masonry components on the outer leaf 6 of the cavity wall and another building component installed in the wall such as a window or door. The structural support 1 is only supported by the outer leaf 6 of the cavity wall. The structural support 1 does not engage the inner leaf 7 of the cavity wall. The structural support 1 is self-supporting within the cavity. This mitigates the requirement of mechanically fixing the structural support 1 to the inner leaf 7 of a cavity wall and thereby reduces the amount of time and material used during the installation of the structural support 1. Further, this allows the profiling of insulation 8 and positioning of the overlap of a cavity facing membrane 9 to be completed independently, once the tray is securely built into the brickwork, as illustrated in figure 1. The structural support is formed from a rigid, non-combustible material. This mitigates against the structural support 1 from bending down inside the cavity. Further, in the event of a fire the structural support will not burn or release flammable vapours which contribute to combustion. The structural support 1 is a one piece structural support. The structural support 1 is a combined lintel and cavity tray having a mechanically fixed stop end. The structural support 1 is a combined single leaf lintel and cavity tray having a mechanically fixed stop end. In the embodiment illustrated, he load bearing arrangement 2 is a single leaf lintel. However, the load bearing arrangement 2 may be any type of lintel. The structural support 1 is elongate. The structural support 1 has a base 10 for supporting masonry thereon. The load bearing arrangement 2 has a base 10 for supporting masonry thereon. The structural support 1 has an upstand 11. The load bearing arrangement 2 has an upstand 11. The upstand 11 is configurable to provide rigidity and strength to the load bearing arrangement 2. This prevents warping of the base 10 of the load bearing arrangement 2. The base 10 is substantially rectangular having two longitudinal sides and two end sides extending between the longitudinal sides. The end sides are locatable between courses of masonry. At least part of the longitudinal sides are locatable between courses of masonry. The upstand 11 extends from the base 10. The upstand 11 extends from the base 10 at an angle between 45° and 90°. In the embodiment shown in figures 1 to 4 the upstand 11 extends from the base 10 at a 90° angle. The upstand 11 extends from one of the longitudinal sides of the base 10. The upstand 11 is co-extensive with the base 10. The upstand 11 is substantially rectangular in shape comprising two longitudinal sides and two end sides extending between the longitudinal sides. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 extends from the load bearing arrangement 2. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 extends into the cavity of a cavity wall. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 extends from the outer leaf 6 towards the inner leaf 7 of a cavity wall. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 is not fixed to the inner leaf 7 of the cavity wall and is not installed between masonry components / bricks of the inner leaf. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 does not engage with the inner leaf 7 of the cavity wall. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 is self supporting within the cavity. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 extends from the upstand 11. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 extends from one of the longitudinal sides of the upstand 11. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 extends from the upstand 11 at a longitudinal side of the upstand 11 opposite to the longitudinal side of the upstand 11 extending from the base 10. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 is coupled to the load bearing arrangement 2. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 is mechanically coupled to the load bearing arrangement 2 via riveting, welding, spot welding, tack welding, adhering, gluing or by any other suitable means and / or is formed by a fold in relation to the load bearing arrangement 2. This ensures a watertight seal between the load bearing arrangement 2 and the arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3. Thereby this prevents moisture making its way underneath the arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 is coupled to the upstand 11 of the load bearing arrangement 2 and / or is formed by a fold in relation to the upstand 11 of the load bearing arrangement 2. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 is coupled to one of the longitudinal sides of the upstand 11 and / or is formed by a fold in relation to one of the longitudinal sides of the upstand 11. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 is coupled to and / or is formed by a fold in relation to the upstand 11 at a longitudinal side of the upstand 11 opposite to the longitudinal side of the upstand 11 extending from the base 10. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 extends from the load bearing arrangement at an angle between 1° and 90°. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 extends from the load bearing arrangement 2 at an incline. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 slopes upwardly from the load bearing arrangement. The arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 has a sloping portion 12. The sloping portion 12 extends from the load bearing arrangement 2. The sloping portion 12 extends upwardly from the load bearing arrangement 2 towards the inner leaf 7 of the cavity wall. This provides a downward flow path for moisture within the cavity towards the outer leaf 6 of the cavity wall and thereby prevents the ingress of moisture within the cavity. The arrangement for delivering internal moisture towards an outer leaf of the cavity wall 3 is a cavity tray. The one or more stop ends 4 have a base 30 and an upstand 31 which extends upright from the base 30 of the one or more stop ends 4. The one or more stop ends 4 have an engagement portion 32 which is configurable to engage with and / or fix onto a surface of the structural support 1. The engagement portion 32 of the one or more stop ends 4 is configurable to form a watertight seal with a surface of the structural support 1 with which the engagement portion 32 engages. The engagement portion 32 of the one or more stop ends 4 is configurable to form a watertight seal at the joint of the stop end 4 with a surface of the structural support 1 with which the engagement portion 32 engages. At least part of the engagement portion 32 is locatable on a surface of the one or more stop ends 4 that engages with a surface of the structural support 1. Each surface of the one or more stop ends 4 that engages with a surface of the structural support 1 has an engagement portion 32. This prevents a gap forming between the stop end and the structural support. Thereby, this prevents moisture on the surface of the structural support from by passing the stop end 4 through a gap between the stop end 4 and the structural support 1. At least part of the engagement portion 32 is locatable on the base 30 of the one or more stop ends 4. At least part of the engagement portion 32 is locatable on a surface of the base 30 of the one or more stop ends 4 that engages with the base 10 of the structural support 1. At least part of the engagement portion 32 is locatable on an underside of the base 30 of the one or more stop ends 4. At least part of the engagement portion 32 is locatable on the upstand 31 of the one or more stop ends 4. At least part of the engagement portion 32 is locatable on a surface of the upstand 31 that engages with the upstand 11 of the structural support 1, in use. At least part of the engagement portion 32 is locatable on a surface of the upstand 31 that engages with the upstand 11 of the structural support 1 such as the trailing edge of the upstand 31 of the one or more stop ends 4. In one embodiment, the base 30 of the one or more stop ends 4 extends perpendicularly from the main planar surface 33 of the upstand 31 of the one or more stop ends 4 and the trailing edge of the one or more stop ends 4 extends perpendicularly from the main planar surface 33 of the upstand 31. At least part of the engagement portion 32 extends perpendicularly from the main planar surface 33 of the upstand 31 of the one or more stop ends 4. This increases the surface area of the engagement portion 32. Thereby, this increases the integrity of the joint of the one or more stop ends 4 on the surface of the structural support to ensure that the one or more stop ends 4 provides a watertight seal. The engagement portion 32 extends across the entire width of the one or more stop ends 4. By width, we mean the measurement of the stop end from the leading edge of the stop end 4 locatable adjacent to the front surface of the outer leaf 6 of a cavity wall to the trailing edge of the stop end locatable adjacent to or beyond the back surface of the outer leaf of a cavity wall and / or opposing to the leading edge. The engagement portion 32 extends the entire height of the one or more stop ends 4. By height, we mean the measurement of the mechanically fixed stop end from the base 30 of the stop end to the opposing end of the base. The engagement portion 32 extends entirely across the length of the one or more stop ends 4. By length, we mean the measurement between the lateral ends and / or sides of the stop end and / or of the base 30 and / or of the upstand 31. The trailing edge 34 of the one or more stop ends 4 is fixed to the upstand 11 and / or sloping portion 12 of the arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall of a cavity wall 3.

The arrangement for draining internal moisture to the external surface of a cavity wall 13 extends vertically upwardly from the upper surface 14 of the structural support. Forming the arrangement for draining the internal moisture to the external surface of a cavity wall 13 as a vertical structure on the structural support 1 reduces the bulkiness of the structural support 1 along the length of the load bearing arrangement 2. This is in comparison to the arrangement for draining internal moisture to the external surface of a cavity wall being formed as a horizontal structure along the base of the structural support. The arrangement for draining internal moisture to the external surface of a cavity wall 13 is configurable to extend at least partially along the width of the base 10. By width of the base, we mean the measurement of the base 10 from one longitudinal side of the base 10 to the other. The arrangement for draining internal moisture to the external surface of a cavity wall 13 is configurable to extend along the width of the structural support 1 from the base 10 of the structural support 1 to at least a part of the arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3.

The arrangement for draining internal moisture to the external surface of a cavity wall 13 is configurable to extend along the upper surface 14 of the structural support 1 from the base 10 of the structural support towards the end of the arrangement for delivering internal moisture towards a load bearing means mountable on the outer leaf of a cavity wall 3 furthest from the base 10 of the structural support 1. The arrangement for draining internal moisture to the external surface of a cavity wall 13 has two upstands 15 and a canopy 16 extending between them. The arrangement for draining internal moisture to the external surface of a cavity wall 13 has a base extending between the two upstands 15. The arrangement for draining internal moisture to the external surface of a cavity wall 13 is hollow. The arrangement for draining internal moisture to the external surface of a cavity wall 13 has a hollow channel between the upstands 15. This enables moisture to flow through the arrangement for draining internal moisture to the external surface of a cavity wall 13. In addition, the canopy 16 prevents mortar or debris falling into and clogging the hollow flow path between the upstands 15 of the arrangement for draining internal moisture towards the external surface of a cavity wall 13. In one embodiment (illustrated in figure 11), the arrangement for draining internal moisture to the external surface of a cavity wall 13 slopes from a trailing end 13b to a leading end 13a of the arrangement for draining internal moisture to the external surface of a cavity wall 13 such that from a side view, the arrangement for draining internal moisture to the external surface of a cavity wall 13 is a right-angle triangle. In another embodiment (illustrated in figure 5), the arrangement for draining internal moisture to the external surface of a cavity wall 13 is substantially an inverted U-shape comprising two upstands 15 and a canopy 16 extending between them. The canopy 16 prevents mortar or debris falling into and clogging the hollow flow path between the upstands 15 of the arrangement for draining moisture towards the external surface of a cavity wall 13. The arrangement for draining internal moisture to the external surface of a cavity wall 13 is hollow. The arrangement for draining internal moisture to the external surface of a cavity wall 13 has a hollow channel between the upstands 15. This enables moisture to flow through the arrangement for delivering internal moisture to the external surface of a cavity wall 13. At least a portion of the arrangement for draining internal moisture to the external surface of a cavity wall 13 is locatable between masonry components on the outer leaf 6 of a cavity wall. At least a portion of the arrangement for draining internal moisture to the external surface of a cavity wall 13 is locatable between adjacent bricks of a wall. At least a portion of the means for draining internal moisture to the external surface of a cavity wall 13 is locatable in the perp joint between masonry components of a wall. This enables moisture to bypass the masonry components / bricks. This is in comparison to the moisture being absorbed by the masonry. The arrangement for draining internal moisture to the external surface of a cavity wall 13 comprises an inlet 17a to allow moisture to flow into the hollow channel between the upstands 15. The inlet 17a is locatable on a rear surface and / or trailing end 13b of the arrangement for draining internal moisture to the external surface of a cavity wall 13. Alternatively, the arrangement for draining internal moisture to the external surface of a cavity wall 13 comprises a plurality of inlets to allow moisture to flow into the hollow channel between the upstands 15. The inlets are locatable along the length of the upstands 15. The arrangement for draining internal moisture to the external surface of a cavity wall 13 has an outlet 17 to allow moisture to flow out of the hollow channel. The outlet 17 is locatable on a front surface and / or leading end 13a of the arrangement for draining internal moisture to the external surface of a cavity wall 13. In use, the outlet is faces away from the cavity of the cavity wall and is flush and / or adjacent to the external surface of the outer leaf of a cavity wall. The arrangement for draining internal moisture to the external surface of a cavity wall 13 has a lip portion 37 which projects from the base 38 of the arrangement for draining internal moisture to the external surface of a cavity wall 13 at the outlet of arrangement for draining internal moisture to the external surface of a cavity wall 13 to project moisture forwardly, away from the external surface of the outer leaf. Advantageously, this prevents moisture being drained onto the external surface of the outer leaf and migrating back into the cavity. The arrangement for draining moisture to the external surface of a cavity wall 13 is non-combustible. The arrangement for draining moisture to the external surface of a cavity wall 13 is formed from steel. The arrangement for draining moisture to the external surface of a cavity wall 13 is formed from stainless steel. The arrangement for draining moisture to the external surface of a cavity wall 13 is a weep. The upper surface 14 of the structural support 1 continues beneath the arrangement for draining internal moisture to the external surface of a cavity wall 13. The base 10 of the structural support 1 continues beneath the arrangement for draining internal moisture to the external surface of a cavity wall 13. This prevents leakage of the moisture flowing through the arrangement for draining internal moisture to the external surface of a cavity wall 13 into the masonry or building elements below the structural support 1 and back into the cavity. While the arrangement for draining moisture to the external surface of a cavity wall 13 has been described as part of the structural support 1 as one embodiment of the structural support 1, it will be appreciated that the structural support 1 is not limited to comprising an arrangement for draining moisture to the external surface of a cavity wall 13.
