Abstract

A structural fitting (1 ) for a cavity wall within a building comprises elongate plates (2) (3) adapted to be supported within the cavity wall, the plate (2) being formed with a plurality of drain holes (4) extending along the length of the structural fitting so as to allow water which enters the cavity wall from above to drain down through the fitting (1 ) to the lower part of the cavity wall, where it is deflected away from the cavity by the imperforate plate (3). The structural fitting (1 ) is of cruciform cross-section.

Description

STRUCTURAL FITTING FOR A BUILDING
The present invention relates to a structural fitting for use in the construction or modification of buildings.
In a building which comprises one or more levels or floors of flats (apartments) the outer walls of the buildings are usually formed as a cavity wall defining a space between inner and outer leaves of the wall which space generally extends from the top of the building to the bottom.
The space in the cavity walls can be filled with insulating material either during the main construction of the building or at a later stage.
It is desirable to prevent any water and/or small additional pieces of insulating material from mixing with the main body of insulating material.
Further, the portions of the outer cavity wall which coincide with each level of flats can be selectively filled with insulation or left empty depending on the wish of the building constructor or the wish of the person or person occupying each level of flats.
According to a first aspect of the invention there is provided a structural fitting adapted for installation in a cavity of a cavity wall in a building, comprising an elongate member, adapted to be supported within the cavity and formed with a plurality of drain holes extending along the length of the structural fitting, and a deflector means, the arrangement being such that water in the cavity above the fitting passes through the holes to the deflector means and then to the outer wall of the cavity.
The detector means may comprise a second elongate member which is adapted to extend across the cavity and to deflect to one side of the cavity any water which enters the cavity from above. This provides a barrier across the cavity.
The elongate members may suitably each comprise a plate, preferably a metal plate. This provides for ease of construction as the plates may be secured together as by welding.
The or each plate may be inclined with respect to the leaves of the cavity wall. This provides for a positive action in deflecting water to the outer wall of the cavity.
The two plates may comprise a cruciform cross section with the row of drain holes located in one plate. This construction is particularly suitable for installation in a cavity wall.
The holes may be uniformly spaced apart along the length of the one plate. This provides for a positive ejection of water along the length of the fitting, which suitably extends the length of the cavity in use.
According to a second aspect of the invention, there is provided a se.t of parts comprising a structural fitting as hereinbefore defined, and a support means or supporting the fitting in position in a cavity wall.
According to a third aspect of the invention there is provided a building, comprising a cavity wall and a structural fitting as hereinbefore defined installed in the cavity. There may be a plurality of said structural fittings spaced apart over the height of the cavity. This provides for water ejection from the cavity and catching of insulation or mortar, over the height of the cavity.
The or each structural fitting may be mounted in the cavity by sliding to provide a tight fit in the cavity, for example by being braced against the respective leaves of the cavity wall.
One or each structural fitting may be supported in the cavity from below by a support means, for example by a pin or shaft extending transversely of the cavity, suitably, the pin or shaft may be made of metal.
There may be insulation material in the cavity, which may be supported in place in the cavity by the structural fitting.
Where the building is a multi-occupancy apartment building, the insulation materials may be coincident with a discrete apartment. Thus one or more other apartments may not have insulation material in the cavity at the level of that one or other apartment(s).
The structural member fitting may be adapted to hold the insulating material in position in the cavity.
The fitting may be adapted to prevent relatively small pieces of insulation material from falling into the cavity. In order that the invention may be more readily understood reference will now be made to the accompanying drawings, in which:
Fig. 1 is a schematic perspective view of a structural fitting according to the invention;
Fig. 2 is a schematic end view of the structural fitting illustrated in Fig. 1 ;
Fig. 3 is a diagrammatic view of a building containing several levels of flats (apartments) and an outer cavity wall and showing the structural fitting illustrated in Figs. 1 and 2 in position in the cavity wall, and
Fig. 4 shows a schematic view of a further embodiment of structural fitting according to the invention installed in a cavity wall.
With reference to Figs. 1 and 2, the structural fitting 1 comprises two elongate members 2 and 3 each in the form of a metal plate joined together as by welding to form a structure with a cruciform cross section as clearly illustrated in Fig. 2. One member 2 is formed with a row of holes 4 extending along its length while the other member 3 is imperforate. The holes 4 are approximately 5 mm in diameter at approximately 15 mm centres. The overall width of the structural fitting 1 as viewed in Fig.2 is approximately 65 mm or so as to fit tightly across a cavity wall (see Fig. 3).
Fig. 3 illustrates diagrammatically a building having several levels of flats (apartments) 11 , 12 and 13 extending between cavity walls one of which is illustrated at 14 and which has inner 14' and outer 14" leaves defining a cavity 14"' therebetween. The cavity wall 14 is adapted to be filled with insulating material 15 either during the original building or at a later stage. For example, the occupants of flat 11 may want cavity wall insulation material whereas the occupants of flats 12 and 13 may not ant the insulating material.
The structural fittings 1 are adapted to be fitted into the cavity wall by sliding them into the cavity from one end and are dimensioned so that they fit tightly in the cavity 4. The spaces between the structural fittings may be filled with insulating material or left empty as required.
The structural fittings 1 are designed to operate as follows:
If water falls down within the cavity wall it will fall onto the top fitting and will pass through the holes 4 in the upper elongate member 2 onto the lower member 3 and will then flow across the lower member 3 to the outer boundary wall of the cavity wall and be absorbed in the boundary wall or will run down the boundary wall, in either case being directed away from the cavity 14'" by the fitting 1.
If any loose insulating material or other unwanted material falls down within the cavity wall, it will fall onto and be retained by the top (as viewed) structural fitting 1 and will not contaminate or form a bridge on the top of any insulating material or other material positioned below the structural fitting.
With reference to Fig. 4, in which like parts are indicated by like reference numerals, there is for a structural fitting 1 support means 16 in the form of a pin or shaft (of metal in the embodiment) which extends transversely of the cavity 14"' and is mounted at each end in the mortar 17 of the respective leaves 14', 14" of the cavity wall 14. The support means 16 is a rod, pin or shaft of metal, suitably galvanized or of stainless steel, and supports the structural fitting 1as by that fitting resting on it in the cavity 14"'.
It will be understood that reference to "water" herein includes liquid water and water vapour in the cavity which condenses to form liquid water in the cavity.
It will also be understood that a structural fitting as hereinbefore described with reference to the drawings may be incorporated in a cavity wall during a "new build" or alternatively may be incorporated in an existing cavity wall retrospectively.
