Abstract

A wall tie 1 has a struck out tab 10 or a corrugation (not shown) which abuts the face of an insulation slab to hold it adjacent a wall skin 6 in a cavity wall. Drip edges 14 may be provided. <IMAGE>

Description

SPECIFICATION Apparatus for retaining insulating material in position z TECHNICAL FIELD OF THE INVENTION The invention relates to apparatus for retaining insulating material in position, particularly apparatus for positioning thermal or sound insulating material of the sheet or block kind in a cavity of a multi-skin wall.
BACKGROUND ART Multi-skin or cavity walls generally have two skins, an inner and an outer skin each generally being of brick or block or of similar materials, though the inner skin could and sometimes does comprise a timber construction. In either case the skins are separated by a cavity. It has been proposed to fill this cavity with a foam insulating material, primarily to conserve energy by helping to insulate a room bounded by the wall and thus to prevent or hinder heat loss from the room. It has been found that when this insulation, usually by injection of insulating foam material into the cavity, is used, the foam acts as a "bridge" for the passage of moisture from the outer skin to the inner skin, which leads to dampness in the room as well as to the cracking of plaster on the wall in the room.
Consequently, such insulation has, under building regulations, not to fill the whole width of the cavity.
DISCLOSURE OF THE INVENTION It is an object of the invention to seek to mitigate these disadvantages of the prior art but which provides apparatus which allows use of insulating material in a cavity.
According to the invention there is provided apparatus for use in a multi-skin wall to retain sheet or block insulating material in position, comprising a wall tie and, in combination with the wall tie, an upstanding retaining device which in use lies in the cavity between adjacent skins of the wall and which is adapted for retaining sheet or block insulating material in the cavity between it and a skin of the wall.
Thus using the invention the advantages which may be c' .ned are that the wall is insulated and there is no bridge for the passage of moisture from the outside to the inside of the room through the multi-skin wall.
According to a second aspect of the invention there is provided a multi-skin wall including apparatus as hereinbefore defined.
The wall-tie has a preferably planar part or body and the upstanding retaining device may comprise a flange bent out of the plane of that part. The construction is simplified by striking a tongue out of the planar part and bending it up away from the plane of that part.
Alternatively the wall tie which is usually of metal may be folded so as to form a U-shaped flange which is, in use, downwardly open.
An embodiment of the invention is hereinafter described, by way of example, with reference to the accompanying drawings.
BRIEF DESCRIPTION OF-THE DRAWINGS Figure 1 is a schematic longitudinal sectional view of a wall-tie, taken on the line X-X of Fig. 2; Figure 2 is a top plan view of the wall-tie of Fig. 1, but to a smaller scale; and Figure 3 is a side elevational view of part of a two skin cavity wall showing the wall-tie of Figs. 1 and 2 in position.
Referring to the drawings, the wall-tie shown is of metal and is substantially planar with end parts 2 and 3 which have holes or depressions 4 for embedding in mortar between courses of bricks one part 2 being for location in the outer skin 5 and the other part 3 being for location in the inner skin 6 of the cavity wall 7 (Fig. 3).
The wall-tie 1 has a body 8 between the parts 2 and 3 which body 8 in use lies in the cavity 9 of the wall 7. The body 8 has upstanding therefrom a flange 10 which is generally vertical but which has an inclined free end or lip 11. The flange 10 is formed by striking out a tongue from the body 8 in a metal-forming press and bending the tongue upwardly about the point Y. The tongue leaves a hole 1 2 through the body part.
In use, the wall tie 1 is placed in the wall and sheet or block insulating material 1 3 is slid into place so that it rests on the wall tie and its outer surface is engaged by the inner (to the right as viewed) surface of the flange 10. The lip 11 helps to guide the material 1 3 downwardly when inserted from above (as viewed). The insulating material 1 3 is thus retained in position.
A series of wall ties 1 at the same height and spaced along the length of the wall can form retaining devices for insulating material aiong the length of the wall.
Ideally, flange 10 is situated two thirds of the distance across the body 8, in other words in use two thirds across the cavity 9, so that one third of the cavity is free of insulating material, and no bridge for moisture is formed across the cavity.
The wall tie itself has means in the form of drip lips 1 4 to collect moisture and prevent that moisture from passing across the cavity.
Various modifications may, it will be understood, be made. For example, the wall-tie may have one part substantially at right angles to the body for securing to a timber frame inner skin of the wall.
