Abstract

A spring wedge 1 for retaining flashing 8 in a chase 7 in a wall 9 is formed from spring strip and comprises a body portion 2, a downwardly projecting front flange 3 and an inclined rear flange 4. To secure the flashing 8 to the chase 7, the flashing is turned into the chase and is trapped between the body portion 2 and the front flange 3 of the wedge which is compressed into the chase. The inclined spring flange 4 is compressed upon insertion of the wedge and its free edge bites firmly into the top of the chase and serves as a gripping edge to prevent removal of the wedge. After securing of the flashing with such spring wedges, the chase may be pointed in the customary manner, the spring strip may be of metal or plastic. <IMAGE>

Description

SPECIFICATION Wedge for retaining flashing The present invention relates to wedges for retaining flashings in chases in brickwork, concrete or other walls and for retaining visqueen membranes or the like. More particularly, it relates to a novel spring wedge for such purposes to be used in place of customary lead wedges.
The invention consists in a spring wedge for retaining flashing in a chase in a wall, comprising a body portion, a front flange projecting substantially vertically from a front edge of the body portion, and an inclined spring flange projecting from a rear edge of the body portion in the opposite direction to the front flange and forwardly over the body portion.
When used, the wedge is fitted into a suitable chase in a wall with the body portion disposed generally parallel to the bottom of the chase, the front flange extending downwardly over the face of the wall, and the inclined spring flange located in the chase with its free edge engaging the top of the chase. The spring flange is compressed upon insertion of the wedge into the chase and its free edge is arranged to bite into the top of the chase and serves as a gripping edge to prevent removal of the wedge. To this end, the adjacent marginal portion of the spring flange may be angled with respect to the remainder of the flange in a direction to cause the gripping edge to bite more effectively into the top of the chase when the spring wedge is compressed into the chase.A metal or other type of flashing is retained in position by the wedge by being turned into the chase and trapped between the body portion and front flange upon compression of the wedge into the chase. Thereafter, the chase may be pointed with mastic or mortar in order to seal the chase, as is customary practice.
The spring wedge may be formed in one piece from spring metal strip or may be moulded from resilient plastics material. The front flange of the spring wedge may be modified so that other building components or items, such as, cables, trunking, and cover strips, may be readily hung from or attached to the wedge.
Whilst the invention is particularly designed for retaining metal and other types of flashings in wall chases, it will be apparent that it may also be used for securing any sheet material to a suitable groove.
In order that the invention may be more readily understood, reference will now be made to the accompanying drawings, in which: Figure 1 is a sectional view through a masonry wall illustrating a flashing retained in position by a spring wedge according to the invention, Figures 2 and 3 illustrate the spring wedge in its compressed and uncompressed conditions, respectively, and Figure 4 is a perspective view of a modified form of the spring wedge.
Referring to Figs. 1, 2 and 3 of the drawings, the spring wedge 1 is formed in one piece from spring metal strip and comprises a planar body portion 2, a front flange 3 projecting substantially vertically downwardly from a front edge of the body portion, and an inclined spring flange 4 projecting from the rear edge of the body portion in the opposite direction to the front flange and forwardly over the body portion. The wedge may be described as being basically of Z-shape in section and, for brickwork, may have a size similar to that shown in Fig. 2. The free edge 5 of the spring flange 4 forms a gripping edge and the adjacent marginal portion 6 of the flange is angled with respect to the remainder of the flange 4 in a direction to cause the gripping edge 5 to bite more effectively into a chase 7 when the spring wedge is compressed into the chase (Figs. 1 and 3).
In order to secure a flashing 8 to a masonry wall 9, a suitable chase 7 is first formed in the wall, for example, by raking out a mortar joint as shown in Fig. 1, or by sawing, and the flashing 8, which may be of metal, reinforced bitumen or plastics sheet material, is applied to the face of the wall below the chase and turned into the chase. The spring wedge 1 is then pushed into the chase, as shown in Fig. 1. As the wedge is inserted into the chase, the spring flange 4 is compressed towards the body portion 2 and the gripping edge 5 bites into the top of the chase to hold the wedge in place. The flashing 8 is retained in position by being trapped between the front flange 3 and body 2 of the wedge and the underlying parts of the masonry wall. To complete the fixing, the chase 7 may be sealed or pointed with mastic or mortar.
Fig. 4 illustrates a modified spring wedge in which the bottom edge portion 10 of the front flange 3 is bent back on the latter in order to form a channel from which may be hung or to which may be attached cables, trunking or cover strips.
Whilst a particular embodiment has been described, it will be understood that modifications can be made without departing from the scope of the invention.
