DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a clip for attaching tiles of a roof to battens or the like and to an apparatus and method for the installation thereof.
BACKGROUND ART
A method often employed for the installation of concrete roof tiles comprises placing a tile in position so as to overlay two spaced apart roofing battens, fitting a clip to the profiled edge of the tile adjacent one of the battens, and nailing the clip to the side of the batten directly beneath the clipped edge of the tile.
A preferred clip for such a method is described in Australian Patent No. 520403 which discloses a tile clip having a rigid body having a pair of outwardly extending hooks for engagement with adjacent edge portions of an upper tile and of a lower tile of a pair of overlapping roof tiles. Each of the hooks are located on a common side of the rigid body. Fastening means are included which comprise one or a pair of opposed downwardly extending lugs having a plurality of barbs for penetration into an adjacent surface of a tiling batten. The or each lug depends from an elongate flange which is part of the rigid body wherein the flange is oriented at right angles to each hook and an intermediate web located therebetween.
This prior tile clip suffers from a number of disadvantages, including (1) a tendency to rotate or deflect under an applied load and thus can not be used advantageously in situations subject to relatively inclement or extreme weather conditions such as heavy winds; (2) the clip can only be installed using a hammer or other form of impact tool and thus the speed of installation is relatively slow and can only be carried out effectively by an experienced tradesman; (3) the clip can only be produced from relatively heavy grade metal and thus is relatively expensive to manufacture; (4) its installation is time consuming, tiring and subject to error as the tradesman must continually and in sequence, lift and place a tile, pick up a clip and hammer, locate the clip and hammer it home, and then put the hammer down before repeating the process.
This prior installation method is of particular concern because the method is tiring not only because of the repetition, but also because of the awkward position required to nail the clip. Errors occur with tile breakages because the clip is required to be nailed immediately adjacent the tile edge and any small deflection can result in the tile being hit. Additionally, and more importantly, it is not uncommon for the clip to be nailed at a location away from the edge of the tile in order to reduce breakages and speed up the tiling. However, this results in a significantly weakened roof structure which often does not comply with the relevant government safety standards.
DISCLOSURE OF THE INVENTION
It is an object of the invention to overcome, or at least ameliorate, one or more of the above disadvantages.
According to a first aspect of the present invention, there is provided a clip for attaching a roof tile or the like to a batten or similar, said clip comprising:
1) a rigid body;
2) at least one securing member depending from said rigid body in a first direction and adapted to engage a side edge of at least one of said tile or the like; and
3) a fastening member depending from said rigid body in a second direction opposite to said first direction and adapted to secure said clip to said batten or similar.
When staggered bonding of a plurality of said tile or the like is required, only one of said at least one securing member is required; when straight bonding is required, two of said at least one securing member are required.
Preferably, each of said at least one securing member comprises a shank portion terminating in a hook, said hook having a profile which is complementary to the profile of said side edge of said tile or the like. When the second of said securing member is present, its shank portion is shorter so that its corresponding said hook can engage the side edge of a second of said tile which is positioned lower than a tile secured by the first of sai
