Definitions

  • This invention relates to a cavity tray.
  • cavity wall structures comprising first and second spaced walls it is common for moisture to run down the outer of the two walls. It is desirable to take steps to prevent the moisture running down this wall. It is known to provide a cavity tray to collect the moisture.
  • the cavity tray can be in the form of a lintel, in which case it may act as a structural support member, as well as a water collector.
  • a cavity tray comprising a base which is disposed in the outer wall and a rear wall extending upwardly into engagement with the inner wall.
  • the cavity trays may slip about during installation so that there is either no overlap, or so that the overlap is unnecessarily large.
  • a cavity tray for use in a wall structure having first and second spaced walls defining a cavity therebetween said tray being adapted to collect moisture falling in said cavity and comprising a cavity member having a base portion adapted to be disposed in the first wall and a rear wall portion secured to the base portion at a junction extending in a longitudinal direction of the tray and adapted to extend into the cavity, characterised in that at least one locating formation is provided on the cavity member, the or each locating formation being adapted to cooperate with a respective locating formation on an adjacent cavity tray in order to locate the cavity tray in a predetermined overlapping position in said longitudinal direction relative to the adjacent cavity tray.
  • the locating means also serves as retaining means to retain the cavity tray and the adjacent cavity tray in said overlapping relationship: thus, the locating means also serves to restrict sliding movement in at least one direction between adjacent cavity trays.
  • the locating means is also adapted to assist the positioning of a row of bricks on top of the cavity member.
  • the locating formations may be adapted to interlock with one another.
  • the locating means is adapted to permit the cavity tray to be located in a plurality of different overlapping positions on the adjacent tray. This may be achieved by providing a plurality of locating formations at different positions on the cavity member.
  • the rear wall portion may be arranged at an obtuse angle to the base portion.
  • the base portion may also extend partially into the cavity.
  • the cavity member may extend across the cavity between the first and second walls.
  • the cavity member may also include a side wall portion arranged at one end of the base portion; the side wall portion may be arranged at an angle of substantially 90° to the base portion.
  • a further side wall portion may be provided at the other end of the base portion. The or each side wall portion is preferably secured to the rear wall portion.
  • the or each locating formation is provided on the rear wall portion, and more preferably the or each locating formation is provided on both the rear wall portion and the base portion.
  • the base portion is configured to restrict the flow of moisture over the ends thereof, particularly in the region where the cavity tray overlaps the adjacent tray.
  • the base portion may be provided with formations in the form of ribs or corrugations; the ribs or corrugations may run substantially transverse to the longitudinal axis of the base portion.
  • the locating formations may be configured so that they form a projection on one face of the cavity member, and form a recess on the opposite face of the cavity member. This arrangement enables the cavity tray to be disposed in an overlapping relationship with an adjacent tray.
  • the cavity tray may be disposed in an overlapping relationship with two adjacent cavity trays, one on each side.
  • locating formations comprise the afore-mentioned ribs or corrugations.
  • the or each locating formation on the base portion is aligned with the or each locating formation on the rear wall portion so that the locating means on the adjacent cavity tray can interlock with the locating means on both the rear wall portion and the base portion of the cavity tray.
  • the cavity tray may be formed of a plastics material, and may be vacuum formed, or injection moulded.
  • the locating formations can also act as strengthening formations to prevent the material of the rear wall portion and/or the base portion from curling. This is especially important when the cavity tray comprises a vacuum formed plastics material.
  • the locating means is particularly useful because it enables a desired amount of overlap to be provided between adjacent cavity trays.
  • the law of certain countries specifies a minimum overlap, so the locating means enables this overlap to be provided automatically.
  • the cavity trays according to the invention may be classed in at least four different types.
  • the first type is known as horizontal cavity trays; these are especially useful at the junction between vertical cavity walls and flat roof structures.
  • the second type is known as parapet cavity trays; these are especially useful in parapet wall structures.
  • the third type is known as lintel cavity trays; these are especially useful above window and door openings and above canopies.
  • the fourth type is known as abutment cavity trays, and these are especially useful at the junction between vertical cavity walls and pitched roof structures.
  • the cavity tray has drainage means adapted to drain moisture from the cavity member through the first wall.
  • the drainage means is integral with the cavity member.
  • the drainage means comprises at least one channel provided in the cavity member.
  • overflow means is provided to permit excess moisture to be drained onto an adjacent cavity tray. Excess moisture can arise, for example, when the level of moisture is too great to be accommodated by the drainage means alone.
  • the drainage channel is provided with a cover for covering at least part of the length of the channel.
  • the cover may be pivotally mounted so that it can pivot between a position in which it covers the drainage channel and a position in which it does not cover the drainage channel.
  • At least one strengthening formation is provided on the cavity member to strengthen the cavity member.
  • the strengthening formation comprises a locating formation as described above.
