Abstract
The formwork, for use constructing foundations, decking, car parks etc., comprises an elongate element that has a base portion 1 and upstanding therefrom a compression portion 2 that is adapted to form a retaining edge for a bed of poured concrete and which comprises a hollow structure that has at least one deformable surface. Preferably both surfaces of the compression portion are resiliently deformable with the formwork preferably comprising an integral extrusion of plastic material such as PVC, nylon or polypropylene. The compression portion preferably includes apertures 7 at spaced intervals to allow insertion of tie bars to link two adjacent beds of concrete. Also claimed is a shuttering formwork that comprises a removable upper lip 6 that is attached to an upper, in use, edge of the compression element.

SHUTTERING
The present invention relates to shattering or formwork of the type used to form a retaining edge for a bed of poured concrete. More particularly, but not exclusively, it relates to shattering which also includes an integral compression joint.
It is known to construct foundations, decking, hardstanding and car parking areas from concrete poured in a fluid state into an area defined by shattering where it is allowed to set.
For large areas, it is usual to set up metal shattering to define a strip, perhaps 5 to 6 metros wide into which is poured to a required depth, such as 150mm, fluid concrete which is then levelled and allowed to set, preferably overnight. In order to allow for expansion of the concrete during its curing process, a layer of non-woven fibrous material is attached to the shattering to absorb the expansion forces. Once the concrete has cured, the metal shattering is removed and replaced a further width away and the process is repeated.
It is a disadvantage of this method that it takes one day to lay each strip and for a large area, this extends the completion period inordinately.
It is therefore an object of the present invention to provide an easily usable shattering forrnwork around which concrete can be cast on both sides contemporaneously and which forms an integral compression joint between the two beds of concrete, and thereby obviating the need for a fibrous compression mat. The shattering may be extruded from plastics material and is thereby sufficiently cheap to be allowed to remain in place after the concrete has been cast.
According to the present invention there is provided shattering formwork comprising an elongate member having a base portion and upstanding therefrom a compression portion adapted to form a retaining edge for a bed of poured concrete and comprising a hollow structure having at least one resiliently deformable surface.
The compression portion may have both surfaces resiliently deformable to separate two beds of poured concrete.
The shattering formwork may be an integral extrusion of plastics material, such as PVC, nylon or polypropylene.
The compression portion may be apertured at spaced intervals to allow insertion of tie bars linking the two beds of concrete.
The shattering may further comprise a removable lip means attachable to an upper, in use, edge of the compression member.
This lip means may be removed after the concrete has cured.
An embodiment of the present invention will now be more particularly described by way of example and with reference to the accompanying drawing, Figure 1 of which shows in perspective shattering embodying the present invention.
Referring now to the drawing, the shattering comprises an integral elongate extrusion of plastics material such as PVC, nylon or polypropylene. In the drawing, only a short section is shown, but in practice, it may be supplied in lengths of 3 metres or 6 metres, whichever is most convenient.
The shattering comprises a base member 1 which is adapted to lie on a flat prepared foundation. Upstanding therefrom is a compression member 2 which is formed as a hollow body defined by two deformable sidewalls joined by several crosspieces 3. Stability is ensured by angled flange members 4 at the junction between the base member 1 and the compression member 2.
The upper, in use, edge of the compression member 2 is reduced in width to form two shoulders 5. A lip member 6 is detachably fixed to the upper edge of the compression member 2 and sits on these shoulders 5.
The total height of the compression member 2 and the lip member 6 is, in this case, 145mm, which allows a depth of concrete of 1 50mm, as required in many circumstances. Altemative heights may be provided if so desired.
In use, a plurality of shattering formwork extrusions are placed in an area to be concreted, each spaced one from the next by 5 to 6 metres and each having the lip member 6 in place.
The concrete is then poured to fill the areas between the shattering formworks and levelled, possibly by means of a roller extending between the lip members. It is then allowed to cure, possibly overnight. During this curing process, any expansion of the concrete will be accommodated by deformation of the walls of the compression member 2. Once the concrete has cured, the lip member 6 can be removed, while the main part of the shattering remains sacrificially in place within the concrete bed. The space left by removal of the lip member 6 may be filled with a pliable medium, such as mastic or bitumen, to complete the joint of the concrete sections and allow for any expansion of the concrete. Holes 7 are provided at intervals, preferably at every 300mm or 600mm along the length of the shattering formwork, to accommodate tie bars which extend through the shattering from one bed of concrete to an adjacent one to prevent relative vertical or longitudinal movement of the beds once the concrete has set.
As can be seen, the shattering of the present invention is easy to use and is cheap enough to be sacrificial i.e. left in place within the cured concrete, where it constitutes an integral compression joint, thereby obviating the need for fibrous compression materials. It also enables large areas of hardstanding or other concrete structure to be cast more quickly, and more easily.
