Abstract

Roof tiles cut from discarded vehicle tyres are laid on a roof in an overlapping manner. One fixing means is used per tile to secure the tile to the roof.

Description

Roof tiles from tyres.

Background-by combining a waste product with a simple and well-understood construction method, both an environmental problem and the basic need of a watertight roof are addressed. The tiles from tyres idea uses simple tools, no chemical or heating processes and a conventional construction method to make easy to use roofing products.

Waste tyres are cheap or free and are found in abundance throughout the world and as the tiles from tyres idea is quick and easy to learn it is an ideal solution to high cost building products and shortages. The essential features of the tiles from tyres idea is turning a major waste problem into a useable product using hand tools or simple machinery. The product is easy to use, easy to handle and potentially, infinitely reusable.

The waste tyre must be laid flat on the floor or suitable bench. With a sharp Cstanley'type knife or simple machine a cut is made from the centre to the outside of the tyre wall, as illustrated in Diagram 1 Side view. The central rim of the tyre wall will require a strong pair of snips or angle grinder to cut the steel ring. With the tyre secured a cut is made around the outside treaded edge, as indicated in Diagram 1 Top View, this gives a segment which is illustrated at bottom of Diagram 1. This segment is further cut to give a workable roof covering tile, these two final cuts'square'the ends of the tile to give a neat finished look to the completed roof.

Given a suitable roof construction, at the correct angle, the tyre segments can be laid out and fixed as illustrated in Diagram 2. Starting at the bottom of the roof structure a single row is completed, fixing each segment with a nail or similar fixing. When one row is complete the next row can be laid over the bottom row allowing for the correct overlap which will ensure no water can run under the tile segments. As each successive row is added the direction of the tiles in the new row is alternated, giving an S shape to the pattern, this is shown in the Plan view I on Diagram 2. The overlapped segments form a channel, which allows water to run easily down to a collection point away from the building. Section A-A shows the resultant pattern.

When the roof structure is covered with the base layer, with the concave face of the segments facing upwards, the top layer can be added. Plan view 2 on Diagram 2 shows the pattern the top layer will make, when laid on the base layer, concave face down. By laying the top layer in a half-and-half pattern the gap between the base layer segments is covered, thus the top layer is channelling rain water into the concave shape of the base layer, as shown in section Al-Al, this forms a waterproof roof covering. The water then runs down this channel and away. The top layer is fixed in the same way as the base layer and is overlapped by the same amount, the sketched detail on page (3/3) illustrates the finished view of the roof covering system.

Claims (1)

1. The claims The basis of the claim is the process to make a reusable Roof covering, manufactured from disused vehicle tyres and the application of this roof covering to suitable roofs ; this is possible when the tyre is cut in the appropriate way therefore making a suitable alternative to a"pan-tile"type of roof covering.
