Description

FIELD The present invention relates to a method of constructing a cavity wall. The invention also relates to a masonry support for use in the method of constructing a cavity wall. BACKGROUND Construction of a cavity-walled building typically comprises building a cavity wall as an early step, before adding a roof, insulation and completing a first fix internally. A cavity wall is constructed using a scaffolding structure for access and support during construction. The scaffolding structure is typically provided external to the footprint of the building before or during construction, and removed once the building is complete. The cavity wall typically comprises an inner and an outer wall, made of block and brick, respectively. During normal construction, both of the inner and outer walls are built to their full heights at the same time which is slow. Moreover, it is not usually possible for bricks in the outer wall to be laid in rain or poor weather so this hinders progress in constructing the cavity wall, and can slow down completion of the building. Blockwork for an inner wall is less reliant on fair weather, but it is not typical for inner block walls to be built before corresponding brick outer walls due to the inner wall being less stable than the outer wall, and requiring support during construction. One way of improving timescales for constructing buildings includes replacing the block inner wall with a timber frame. This can be quicker and mean that a roof can be added before outer walls are built but is more expensive and can give rise to settlement issues. Ideally, a builder would want to build inner blockwork up to its full height alone so that a roof can be added. This would enable the building to be made watertight so that internal work can then progress. Such internal work would typically include completing the first fix, plastering and other internal fixings before outer wall brickwork is required to be complete. It is therefore desirable to provide a method of constructing a building that includes supporting the inner wall during construction to allow the building to be made watertight and to be substantially completed internally. This would speed up the construction process, making it more efficient. It would also make the process more predictable and less reliant on good weather conditions to complete.

DETAILED DECRIPTION In brief overview, a method of constructing a cavity wall comprises using a masonry support 100. Constructing the cavity wall comprises constructing a first wall and a second wall spaced from the first wall. A scaffolding frame for support in construction of the cavity wall is provided. The method involves constructing a section of the first wall and connecting a part of the section of the first wall to a part of the scaffolding frame using a masonry support, thereby providing support to the first wall during construction. The masonry support 100 comprises a plate 102 for engagement with blockwork. The masonry support 100 comprises an engagement arm 110 extending from the plate for 102 engagement with a scaffolding frame. Fig 1 shows the masonry support 100. The masonry support 100 is made of metal. In examples, the masonry support may be formed of aluminium, steel, titanium, or other metals, or of plastics or composite material such as carbon fibre. The construction and material of the masonry support 100 is such that the masonry support is sufficiently strong to provide sufficient support to the first wall during construction through the connection to the scaffolding, and such that over the lifetime of the cavity wall it is resistant to degradation through corrosion or the like. The masonry support 100 comprises a plate 102. The plate 102 is rectangular, in plan view. The plate 102 is substantially flat. In other words, the plate 102 lies in one plane. The plate 102 is 7mm in thickness. In examples, the plate 102 may be more or less thick than 7mm. Advantageously, the plate 102 has a thickness that is substantially the same as the thickness of a layer of mortar or other binder used in the construction of blockwork. This means that the support can be seamlessly integrated into the wall without disturbing the layout of the blockwork. The plate 102 comprises opposing edges, first edge 106 and second edge 110. Referring to Figure 2, the plate 102 comprises a first side 104. The first side 104 projects from the first edge 106 of the plate 102. The first side 104 projects from the first edge 106 in a direction perpendicular to the plane of the plate 102. The plate 102 comprises a second side 108 that projects from the second edge 110 of the plate. The second side 108 projects in the same direction as the first side 104. The second side 108 is opposite and facing the first side 104. The second side 108 is substantially identical to the first side 104. With the plate 102 arranged horizontally, the first and second sides 104, 108 project vertically, for example vertically downwardly from the plate 102. The internal width of the plate 102 between the first side 104 and the second side 108 is substantially the same width, or in any event at least the same width as a standard block used in construction. In examples, the internal width of the plate may be 100mm more than the width of a block. In use, the first side 104 abuts a first side of a block and the second side 108 abuts a second side of the block when fitted over the block. This allows for a tight and secure fit when the masonry support 100 is in use. This also means that the masonry support 100 is self-centralised on the block for suitable positioning of further blockwork. The width of the block may be around 100mm. The internal width of the plate may be 100mm. In examples, the internal width of the plate 102 may be greater than 100mm but less than 120mm. In examples, the internal width of the plate 102 may be around 140mm. In examples, the internal width of the plate may be 100mm or the internal width of the plate 102 may be greater than 100mm but less than 120mm. In examples, the plate 102 may be bigger or smaller, as appropriate for the relevant application. In examples, the first side 104, and / or the second side 108 may diverge from one another away from the plate 102, such as being angled away from one another. The angle of each, or both may be less than 5 degrees from the vertical. The first side 104 and / or second side 108 may thus form an introducing portion to guide the masonry support 100 into engagement with a block, in use, with a tight fit achieved when the masonry support 100 is fully engaged with the block. In examples, the second side 108 may be omitted from the plate 102. In examples, both of the first side 104 and the second side 108 may be omitted. The plate 102 has apertures through the plate 102. The plate has four apertures 112. In examples, more or less than four apertures 112 may be provided. The apertures 112 are evenly spaced across the plate 102. The apertures 112 are circular. In examples, the apertures 112 may be square or a different shape. Advantageously, the apertures 112 allow for mortar or a binder to pass through the plate 102. The mortar or binder may be provided over and / or around and / or through the masonry support 100. This means that the masonry support 100 can be fully integrated into the structure of a wall. As such, it is suitable, and indeed intended, to be left in the wall once construction has been complete, without compromising the strength of the wall. The masonry support 100 comprises an engagement arm 120. The engagement arm 120 projects from the first side 104 of the plate 102. The proximal end 121 of the engagement arm 120 is attached to the first side 104 of the plate. The distal end 122 of the engagement arm 120 is configured to engage with part of a scaffolding frame. The engagement arm 120 projects in the same plane as the plate 102. In use, the engagement arm 120 extends horizontally from the plate 102. In use, the engagement arm 102 engages with a part of the scaffolding frame. For example, the engagement arm 120 may engage with a scaffolding tube, or a scaffolding clamp. The engagement arm 120 is a hollow cylinder. The engagement arm 120 is dimensioned to abut a scaffolding tube of the scaffolding frame which is provided. The outer diameter of the engagement arm 120 may be 48.3mm. This means that the engagement arm 120 may closely fit with a standard scaffolding tube. This provides a reliable connection between the engagement arm 120 and, in turn, the masonry support 100 and the scaffolding frame. In examples, the diameter of the engagement arm 120 may be larger than, or smaller than, the diameter of a scaffolding tube. This means that the masonry support 100 may be used with different types or parts of a scaffolding structure. In examples, the diameter or angular position of the engagement arm 120 relative to the plate 102 may be adjustable. As such, a secure connection between the engagement arm 120 and a scaffolding tube may be provided. For example, by aligning the engagement arm 120 with, and / or tightening the engagement arm around a scaffolding tube. The means that the masonry support 100 is flexible and suitable for different applications. In examples, the engagement arm 120 may comprise a further coupler. For example, the engagement arm 20 may comprise a swivel coupler, double coupler, or key clamp fitting. Advantageously, this allows for a maximum amount of flexibility for connection to a part of a scaffolding frame. In examples, the engagement arm 120 is removable after use. The engagement arm 120 may be releasably attached to the first side 104 so that it can be easily removed from the plate 102. In examples, the engagement arm 120 may be removed by cutting the engagement arm 120 close to its proximal end 121. In examples, the engagement arm 120 may not be removed and may project into the cavity of the cavity wall. This advantageously means that the engagement arm 120 does not require additional removal, thereby not adding additional time to the construction of the cavity wall. In examples, such as in the example shown in the side view of Figure 3, the masonry support 100 comprises a second engagement arm 130. The second engagement arm 130 projects from the second side 108 of the plate 102. The second engagement arm 130 projects opposite the first engagement arm 120. As such, the first engagement arm 120 and the second engagement arm 130 are arranged symmetrically with respect to the plate 102 The second engagement 130 arm may be identical to the first engagement arm 120. The second engagement arm 130 has the same dimensions as the first engagement arm 120. In examples, the second engagement arm 130 may differ to the first engagement arm 120. For example, the diameter may be different and / or one of the first engagement arm 120 or the second engagement arm 130 may comprise a further coupler. Advantageously, providing a second engagement arm 130 means that the vertical spacing of the masonry supports 100 may be increased while not compromising the support provided to the first wall by the masonry support 100. Referring to Figure 4, a part of a cavity wall 200 comprising a first wall 210 and a second wall 220 is shown. The second wall 220 is spaced apart from the first wall 210. A cavity 230 is provided between the first wall 210 and the second wall 220. In examples, the first wall 200 is an inner wall and the second wall 220 is an outer wall. The masonry support 100 is provided on top of a first section of a first wall 200. The first wall 210 comprises blocks 212, 214. The second wall 220 comprises bricks 222. In use, a section of the first wall 210 is constructed using at least one block 212. Mortar or another construction binder is applied between blocks 212, 214 of the first wall 210. A masonry support 100 is provided. The masonry support 100 is engaged with a part of the section of the first wall 210. The masonry support 100 is placed on top of a first block 212 of the first section of the first wall 210. The plate 102 is placed on the top side of the first block 212. The apertures 112 in the plate 102 allow for mortar to pass through the masonry support 100. The first side 104 of the masonry support 100 engages with a first side of the first block 212. As a further block 214 is added on top of the first block 212, the masonry support 100 is sandwiched therebetween. As the second wall 220 is constructed, the engagement arm 120 of the masonry support 100 projects into the cavity 230 between the first wall 210 and the second wall 220. This is shown in Figure 5. As will be appreciated, the masonry support can be used with the first and second sides 104,108 projecting upwardly, if desired, and a further block 214 brought into engagement therewith, after the plate 102 is placed on top of mortar / a first block 212. Referring to Figure 6, the method 300 of constructing the cavity wall 200 is schematically shown. At 301, once ground preparatory works have completed, a scaffolding frame is provided. The scaffolding frame may comprise multiple components, scaffolding tubes, and relevant parts to act as a support structure during construction of the cavity wall 200 and / or building. The scaffolding frame is provided external to the footprint of the cavity wall 200 and / or building to be constructed. The scaffolding frame is erected to a height suitable to support the building of the cavity wall 200 to its full height. In examples, part of the scaffolding frame is provided and the height and / or extent of the scaffolding frame is increased as the wall height is built. At 302, a first section of the first wall 210 is constructed. The first wall 210 is an inner wall. The first wall 210 comprises blocks. In examples, a first row of blocks may be laid to provide the first section. In examples, more than one row of blocks may be laid to provide the first section. At 303, the masonry support 100 is engaged with a part of the first section of the first wall 210. In particular, the plate 102 of the masonry support 100 is provided on top of a block of the section of the first wall 210. The block is part of the section of the first wall 210. The first side 104 of the support 100 abuts a first side of the block. As such, the support is securely engaged with part of the section of the first wall 210. In examples, the masonry support 100 comprises a second side 108. The second side 108 abuts a second, opposing side of the block. Advantageously, this provides an improved and secure engagement between the masonry support 100 and the part of the section of the first wall 210. At 304, the masonry support 100 is secured to a part of the scaffolding frame. The engagement arm 120 that extends from the plate 102 of the masonry support 100 is secured to the scaffolding frame. The engagement arm 120 abuts a scaffolding tube of the scaffolding frame. In examples, the engagement arm 120 is tightened around a part of the scaffolding from for secure engagement. In examples, a further coupler, such as a swivel coupler, double coupler or key clamp fitting is provided to facilitate a secure engagement between the engagement arm 120 and the part of the scaffolding frame. In examples where a second engagement arm is provided on an opposing side of the masonry support 100, a further scaffolding frame may be provided to engage the support and, in turn, support the first wall 210 during construction. Together, steps 303 and 304 relate to connecting the part of the section of the first wall 210 to a part of the scaffolding frame using the masonry support 100. As such, the scaffolding frame supports the masonry support 100 which, in turn, supports the part of the section of the first wall 210 during construction. At 305, mortar or another suitable construction binder is provided on the section of the first wall 210. In examples, mortar may be provided before step 303, i.e. before the masonry support 100 is engaged with a part of the first section of the first wall 210. The apertures 112 in the plate 102 of the masonry support 100 allow for mortar to pass through the plate 102. Advantageously, this means that the masonry support 100 is fully integrated into the first wall. This means that the support is securely engaged within the wall to increase the support provided to the first wall during construction. It also means that mortar may be provided fully between blocks so that the strength of the first wall 210 is not compromised by using the masonry support 100. At 306, a further section of the first wall 210 is erected. Erecting the further section of the first wall 210 comprises adding further blocks and binder around and / or on top of the first section. In examples, the blocks may be added in a boustrophedon arrangement. Advantageously, this allows for the walls to be constructed in the most efficient way. At 307, the further section of the first wall 210 is connected to the scaffolding frame using a further masonry support. The further masonry support is the same as the masonry support 100. The masonry support is engaged with part of the further section of the first wall. The masonry support is secured to a different part of the scaffolding frame. Advantageously, providing a further masonry support means that the first wall 210 has additional support during construction. Steps 305, 306, and 307 are repeated until the first wall 210 is erected to its full height. Further sections of the first wall 210 are erected and further masonry supports 100 are added during construction of the first wall 210. The further masonry supports 100 and the further sections of the first wall 210 may be added to the side, on top of, or offset from other masonry supports 100. Advantageously, this means that the first wall 210 is sufficiently supported to be completed without the need to construct the second wall simultaneously. This makes the construction of the cavity wall more efficient. Moreover, the first, or inner, wall can be built in any weather conditions so is not dependent on fair weather to be constructed to its full height. This may lead to considerable time savings during the building process. In examples, different variations of the masonry support 100 may be provided during construction of the first wall. For example, a masonry support with a different engagement arm and / or a further coupler may be provided depending on the requirements for that part of the first wall 210. In examples, a corner of the cavity wall may be provided with a masonry support 100 comprising an engagement arm 120 with, for example, a swivel coupler to ensure that the corner of the first wall is supported effectively. At 308, a roof structure may be added and / or the internal first fix may be started. The method 300 may comprise building four or more internal walls such that the first walls of a building are completed. Each wall may be built using the method described herein, or one or more of the walls, or part of one or more of the walls may be constructed using the method. By providing the support during construction and building the first walls to their full height, a roof structure can be added prior to erecting the second wall. This means that the building can be made watertight earlier in the construction process, without being hindered by unfavourable weather. It also means that an internal first fix and can be commenced without the second wall being constructed. In examples, the first fix includes steps such as plastering, flooring, and providing electrical and water supplies throughout the building. Advantageously, this means that the second wall can be constructed at the same time as the internal first fix, making the building process more efficient. At 309, the masonry support 100 is disconnected from the scaffolding frame and the second wall 220 is erected. The masonry supports 100 remain in the first wall 210. In other words, the masonry supports 100 do not require removal from the first wall 210. Advantageously, the masonry supports 100 do not negatively affect the strength of the first wall 210 once disconnected from the scaffolding frame. This means that the masonry supports 100 are sacrificial. Advantageously, this means that extra time and / or labour is not required for removal once the second wall 210 has been erected and the time savings gained are not lost at a later stage of construction. The second wall 220 is erected to its full height. The second wall is erected using bricks, as shown in Figures 3 and 4. In examples, the second wall 220 is erected using blocks. The blocks in the first wall 210 may be smaller than the blocks in the second wall 220. The second wall 220 and the first wall 210 together form a cavity wall 200. In examples, the cavity wall 200 is a building wall, such as an exterior wall of a building. In examples, the exterior wall may be the exterior wall of a house. At 310, the method may further comprise adding insulation into the cavity 230 of the cavity wall 200. In examples, the insulation may be provided on a side of the first wall 210 prior to erecting the second wall 220. This may be advantageous to improve timescales and accurately apply the insulation. The insulation may surround the engagement arms 120 of the supports 100 that are remaining in the first wall 210 and project into the cavity 230. As such, no further modification of the masonry supports 100 is required once the first wall 210 has been erected. In examples, at least some of the engagement arms 120 may be removed from the masonry supports 100 prior to adding insulation. The engagement arms 120 may be releasably attached to the plate 102 so that removal is simple and efficient. In examples, the engagement arms 120 may be releasably attached to the plate 102 using bolts. The bolts may be screwed into threaded portions provided on one or both of the plate 102 and / or the engagement arm 120. In examples, two threaded portions may be provided on the first side 104 of the plate 102, to couple with bolts that pass through corresponding holes in a flange of the engagement arm 120, such as a flange that projects on both sides of the engagement arm 120 with a hole on each side thereof. For removal, the engagement arm 120 may be unbolted such that it can be separated from the plate 102. Advantageously, this may be quick and simple, and ensure that engagement arm 120 is removed from the plate 102 in its entirety. It may also advantageously mean that the engagement arm 120 is not damaged and could be reused in combination with new plates 102. This would reduce wastage and be more environmentally friendly. In examples, a substantial part of the engagement arms 120 may be cut away from the plate 102. This may increase efficiency of the process for adding insulation and so result in time savings overall. Additionally or alternatively, the second engagement arms 130 may be similarly removable. Although a few example embodiments have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications might be made without departing from the scope of the invention, as defined in the appended claims.
