Abstract
Description
- The present invention relates to a cavity tray system for use in cavity wall constructions, particularly where an insulating material is to be located in the cavity adjacent the inner leaf.
- When a conventional damp proof course (DPC) in the form of plastics or lead sheeting is used in a conventional cavity wall there are various drawbacks. The insulation to be attached to the inner leaf must be cut on site; this tends to be carried out very roughly inaccurately, leading to potential defects where the DPC passes over it, including punctures etc. Furthermore, the DPC tends not to follow the vertical surface of the insulation closely, resulting in a reduction in the effective cavity width. Additionally, there are further potential defects where lap joints between adjacent DPC sheets are unsupported.
- The use of cavity trays in place of single DPC sheets represents an improvement, however even this present significant disadvantages. The insulation must be cut on site to allow the cavity tray upstand to fit into it. There tends to be an ineffective contact between the cavity tray upstand and the insulation (or the inner leaf itself) resulting in a potential route for the ingress of water. The pre-attached lead flashing which is generally provided makes the apparatus difficult to handle and is liable to damage.
- These drawbacks are even more serious in the case of a stepped conventional cavity tray system used when a cavity wall abuts an inclined surface such as a pitched roof. Under these circumstances, each block of insulation may need to be cut at three levels to accommodate the upstands from trays associated with different brick courses. A great deal of on-site cutting and sizing is required both of the flashing and the trays themselves.
- It is an object of the present invention to provide a cavity tray system which avoids or minimises the above disadvantages.
- It is a further object of the invention to provide such a system which is particularly suitable for use in a stepped form.
- According to the invention, a cavity tray system comprises: a tray and a cavity unit; the tray including a generally horizontal base and an upstand extending generally upwards and rearwards; the cavity unit including means to receive the upstand, a generally horizontal web extending rearwards and a generally vertically extending insulation member.
- Thus, in use, the web of the cavity unit would be located in the mortar joint between two brick courses in the inner leaf, with the insulation against the inner leaf surface, and the tray would be positioned with the edge of the upstand located e.g. in a channel in the cavity unit with the base located in the mortar joint between two lower brick courses in the outer leaf, so that the tray spans the cavity.
- Since the upstand is received by the cavity unit, a far more effective moisture barrier may be produced. Also, the insulation does not need to be cut.
- The tray and cavity units are preferably made from a plastics material. The tray may include a stopend which may be integral or detachable and hence adjust-able in position. The tray may also include some means at its front edge for attaching a flashing. This may be a simple elongate channel or may provide a more complex interlocking profile.
- The system of the invention contemplates the incorporation of a suitable flashing, e.g. of lead or a plastics material. The flashing may include an edge formation which is arranged to co-operate with the front edge of the tray. The edge formation may be of a plastics material which is less flexible than the flashing itself.
- The web on the cavity unit is preferably continuous but may be interrupted. The means for receiving the upstand is preferably a channel defined by a main vertical wall and an overhang. The overhang may include strengthening ribs. There may also be strengthening ribs on a top wall portion extending rearwards as far as the web. Preferably, the insulation is attached (e.g. by gluing, welding etc.) to the underside of the top wall portion and to the rear of the main wall.
- Where the system is intended for use in a stepped situation, the cavity unit may have a series of overhangs forming a corresponding series of channels at different levels, each arranged to co-operate with the upstand of a tray associated with a particular brick course. In this case, the tray and flashing would tend to be shorter in length, and a stopend would be provided at each level.
- Where a continuous tray may be required, a joint may be provided between adjacent lengths of cavity unit and tray. This may simply take the form of a cover plate and a tray cover. The cover plate preferably follows the shape of the cavity unit upper surface and overhang and may include a recess arranged to accommodate two strengthening ribs which may be located at the ends of the adjacent cavity units. The tray cover may simply comprise a sheet following the shape of the tray which can be located over the joint between adjacent trays and may extend into the channels formed by the adjacent cavity units.

- Figures 5A to 5C are successive sectional views showing the fixing of the flashing;
- Figures 6, 7 and 8 are isometric sections showing three alternative methods for fixing the flashing;
- Figure 9 is an exploded isometric view of a joint in a continuous system;
- Figure 10 is an exploded isometric view of a stepped tray system;
- Figure 11 is a vertical section through a cavity wall incorporating the system of Figure 10; and
- Figure 12 is an isometric view of the system of Figure 10 in use in conjunction with a pitched roof.
- Figure 1 shows the basic components of the cavity tray system. They include a cavity unit 11 and a tray. There are two forms of tray, namely, a
tray 12 for use without flashing and atray 13 for use with flashing 14. A stopend 15 may also be provided. Thestopend 15 is shown seperate, in which case it may be movable relative to thetray - The cavity unit 11 is of a plastics material and is elongate and generally right angled in section, thereby defining a main vertical wall 16 and a top horizontal wall 17. An
overhang 18 extends along the main wall 16 forming arecessed channel 19.Strengthening webs 21 extend over theoverhang 15, up the main wall 16 above and back across part of the top wall 17 leaving a plainflat web 22 extending rearwards beyond. A block ofinsulation 23 is fixed to the inside surface of the main wall 16 and to the undersurface of the top wall, the thickness of the insulation corresponding to the extent of theribs 21. The main wall 16 is folded beneath theinsulation 23. - The
tray 12 is an elongate plastics sheet which is also generally right-angled in cross-section. It includes ahorizontal base 24 and anupstand 25. Theupstand 25 has atop edge portion 26 which is displaced slightly rearwards. Thetray 13 is identical to thetray 12 other than in one respect, namely, the presence of agroove 27 along the front edge. - The flashing 14 is an
elongate lead sheet 28 with an insert section 29 attached along one edge. The stopend is of plastics material and follows the general profile of thetray 12. - An assembled system is shown in Figure 2 in connection with a cavity wall including an
inner leaf 31 and anouter leaf 32. Theweb 22 is located on top of a course of bricks orbuilding units 33 with the insultation in contact with the outer face of theinner leaf 31. Thetop edge portion 26 of thetray 12 is located in thechannel 19 and the base is positioned on top of a course ofbricks 34 in theouter leaf 32. A layer of mortar (not shown) would be formed on each side of both theweb 22 and thebase 24 and another course of bricks and/or other units would be positioned above. The relative positions are shown more clearly in Figure 4. - The
stopend 15 is simply located at a convenient position along thetray 12 and within thechannel 19. It can be slid into position with its upper part in thechannel 19, so affording an adjustability to suit the perpends of the external brickwork. This minimises the need to cut bricks to size. - The assembled system shown in Figure 3 is similar to that shown in Figure 2 except that no stopend is provided but a flashing 14 is provided. The flashing 14 is located by inserting the insert section 29 into the
groove 27 along the edge of thetray 13. This is shown in more detail in Figures 5A to 5C. The insert section 29 comprises afold 35 along the edge of the flashing 14 and atoe strip 36 having a tapered cross-section. To fix the flashing 14 in position, thefold 35 is pushed into the channel 19 (Figure 5A). Thesheet 28 is bent down until it is flush with the wall (Figure 58). Thetoe strip 36 is then driven home into thefold 35, with its tapered section forcing the lead of the flashing 14 into a secure engagement. - Alternative fixing profiles for the flashing are shown in Figures 6 to 8. In Figure 6, the edge of the
tray 41 has abead 42 defining acurved recess 43. Thelead sheet 28 includes a curved sectionplastics edge strip 44 which locates in thecurved recess 43. In Figure 7, thetray 51 has a T-sectionedslot 52 while thelead sheet 28 has a correspondingly shapededge strip 53 which is inserted into theslot 52 from one end. In Figure 8, the tray 61 has a hook-sectioned slot 62 while the lead sheet has a correspondingly shapededge strip 63 which is inserted from one end. - In all cases, a waterproof joint between the flashing 14 and
tray 13 is provided. - In order to form a waterproof joint between adjacent lengths of cavity unit 11 and
tray 12, an arrangement such as that shown in figure 9 may be used. Acover plate 71 and atray cover 72 are required. Thecover plate 71 is of plastics material and follows the shape of theweb 22, the top wall 17, the upper part of the main wall 16 and theoverhang 18 of the cavity unit 11. It also has arecess 73 corresponding in shape to theribs 21. Thetray cover 72 is simply a short length of plastics sheet bent to follow the shape of thetray 13. - The joint is formed over the junction of two abutting units by locating the
tray cover 72 in position over the joint line between twoadjacent trays 13, with itstop edge 74 spanning the tworecesses 19. Thecover plate 71 is positioned over the joint line between the two adjacent cavity units 11 with the twoend ribs 75 located within thecavity 73. Both thecover plate 71 and tray cover 72 are preferably glued in position. - The system of the invention is particularly applicable to a stepped cavity tray arrangement. Figure 10 shows the basic components for a three-tier stepped construction. They include a
cavity unit 81, atray 83, and a flashing 84. Thetray 83 and flashing 84 are very similar in construction to thetray 13 and flashing 14 but are rather shorter in length. Threetrays 83 andflashings 84 may be used with eachcavity unit 81. - The
cavity unit 81 is very similar to the cavity unit 11 except that there are threeoverhangs 88 at three different levels, separated from each other by a spacing equal to the height of one brick course. These therefore form threechannels 89. - The interconnection is shown in Figure 11, and as can be seen, it is identical to the interconnection shown in the earlier embodiments though there are three connections at three levels, in place of the one connection necessary in the earlier embodiments. In each connection, the top edge of a
tray 83 is located in one of thechannels 89 and the base of thetray 83 is located on top of the appropriate brick course. - The overall construction is shown in Figure 12. Three
trays 83 are positioned with respect to eachcavity unit 81 and descend from right to left. Anothercavity unit 81 is then employed, three brick course heights lower, and threemore trays 83 are employed. The flashing 84 from eachtray 83 is bent so as to be flush with the wall until the unction with the roof at which each flashing 84 is bent until it is flush with the roof, with each flashing 84 overlying the adjacentlower flashing 84. This results in a neat aesthetically pleasing yet waterproof construction.
