Description

SPECIFICATION A deformable structure and method of using such a structure This invention relates to a deformable structure which is primarily designed for use in concrete casting operations and also to a method of building construction which uses such a structure when casting concrete parts thereof.
In modern times, the construction industry has made considerable use of concrete both for casting foundations and in the construction of flooring. These techniques have been applicable both to large scale buildings such as offices, factories and blocks of flats we well as to the construction of private dwellings.
However, one of the difficulties which is encountered in building construction resides in the movement of the ground upon which the structure rests. Where this movement is serious, foundations can be disrupted and concrete floors can be either cracked and broken up or can be bodily shifted from the foundations. In the worst cases of such movement, for instance, total destruction of the building can result in that the building can be damaged beyond repair and may need to be demolished for safety reasons.
One cause of such ground movement is found where buildings are constructed on ciay soil. Clay soil, as is known, swells very substantially when wet and can cause for example, a vertical movement of the ground level of 30 mm between its wet and dry states.
The present invention seeks to provide a deformable structure which will enable certain movements of the ground to be taken up while allowing normal building structure procedures, i.e. the use of casting in concrete.
According to the invention there is provided a deformable structure comprising two sheets of material between which is sandwiched a separating arrangement filling at least part of the space between the two sheets, the separating arrangement being formed from a material which is compressible under pressure.
The invention includes a method of building using a deformable structure such as that above referred to.
The invention will now be described in greater detail, by way of example with reference to the drawings, in which: Figure 1 is a part cross sectional perspective view of one form of collapsible structure in accordance with the invention; Figure 2 is a diagrammatic representation for illustrating the relative strength required for these particular constructional considerations.
Figure 3 is a part cross sectional broken away perspective view of a second form of collapsible structure in accordance with the invention; Figure 4 is a part cross sectional broken away perspective view of a third form of collapsible structure in accordance with the invention; and Figure 5 is a part cross sectional broken away perspective view of a fourth form of collapsible structure in accordance with the invention.
Referring firstly to Fig. 1, a part of a board 1 comprising a deformable structure in accordance with the invention, is shown in perspective view with the board cut away to show the internal structure. From this figure it will be seen that the board 1 comprises two sheets 2 and 3 of a suitable material which is not significantly attacked by water, such as chipboard or composition board, which form the outer layers of the present board 1. Sandwiched between these two sheets 2 and 3 is compressible separating medium 4 which, in the example shown, comprises an expanded material which is compressible and is equally not attacked by the presence of water. The expanded material may be an inorganic foam or may be of plastics material. The choice of material used will depend upon the properties which the board is required to have and will be described in greater detail hereinafter.
In the construction of the boards, the outer sheets 2 and 3 may suitably be glued to the separating medium 4 or the separating medium 4 can be firmly attached to the sheets 2 and 3 by being produced in situ between the sheets. Suitable materials for the construction of separating materials include the inorganic foam sold by ICI under the designation IF70 or expanded polystyrene.
The expanded material may have either open or closed cells as desired.
While in the above embodiment it is stressed that it is desired to avoid the action of water on the materials of the outer sheets of boards and also on the sandwiched material between them, it is to be understood that while this permits the use of these boards in conditions of significant moisture, other conditions may permit the use of compressible boards which are only partly or even nonresistant to water.
The boards constructed in accordance with the invention, are suitable for use in the casting of concrete both for foundations and for flooring and any other application that requires the take up of pressure which is subsequently applied to the structure, i.e.
after its construction but which is not present at the time of construction. Thus normal preparation is carried out and the boards are set up to form parts of a mould or mould cavity, i.e. as bases or shuttering and the concrete is then cast therein. Subsequent movement of the surrounding ground or other material which will otherwise act on the cast concrete will act initially on the compressible board.
The board is designed to stand up to pressures which are greater than those which are used in the casting operation namely the forces produced by the weight of the casting material but which give way under the action of forces which would be sufficient to have a deliterious effect on the cast structure.
It will be clear to a structural engineer what the give way point of the board requires to be in any particular circumstances and by the selective use of the various materials available for the construction of the boards, the compressibility of the board can be set over a fairly large range.
Fig. 2 shows diagrammatically the circumstances present in the use of a board in constructing a piece of flooring whereby the forces involved are indicated diagrammatically. Thus Fig. 2 shows the compressible board which lies underneath the concrete floor or slab 9 at 10. Acting on the underside 11 of the compressible board 10 is the force Fs produced by the movement of the soil. On the upper side 1 2 of the board the weight of the concrete slab We acts. Forces Fa present at each end of the concrete slab represent the anchoring forces which anchor the concrete slab against its being pushed upwards. It is to be understood that until there is movement of the ground, once the concrete slab has been set, no forces act on the board.Once however the movement of the ground takes place, it acts with the force Fs upon the underside 1 7 of the board while the forces Fa and Wc produced by reaction of the structure will act on the other side of the board. It is these forces which have been represented. A further force also has to be taken into consideration i.e. the force which, if applied to the concrete slab,will cause it to break up. This force has been referred to as Fb. Thus in general terms, the board should be able to resist without compression the force We but should compress under the action of excess force produced by ground movement i.e. when Fs2Fb and when FsoFc + We.
It is to be understood that the above is an over simplification since the effects, particularly in the break up of concrete, depend on the form of application of force i.e. a force having a point loading will do more damage to the concrete than a force which is spread over an area.
Similar situations also arise with movements and pressures against non horizontal cast structures.
The separating arrangement can take a number of different forms and three of these are shown in Figs. 3 to 5.
In Fig. 3, the foam material is produced in the form of a honeycomb structure 5. This provides for a saving in the foam material and enables significant control over the collapsing pressure, e.g. by use of appropriate dimensioning.
In Fig. 4, there is shown an arrangement using strips 6 of foam material and in Fig. 5 there is an arrangement using blocks 7 of material.
A suitable spacing of the strips or blocks is a one to one ratio, e.g. 6 inches of block or strip and then a 6 inch space.
It will be appreciated that various modifications may be made to the above described embodiment without departing from the scope of the invention.
For example other material may be used as the outer sheets such as hardwood, plywood etc. While the material sandwiched between the sheets has been described as being permanently compressed, i.e. destroyed in certain circumstances, the sandwiched material may be of a more spongy nature and may return to or approach its original dimensions once the compressing forces have been removed.
In the embodiments shown in Figs. 3 to 5, the voids may be filled with other material if desired. This will normally have a lower resistance to compression than the main foam material. In the event of the voids being filled, the compressibility of the boards may be determined by a combination of the properties of both the main foam and the filler.
Any other desired configurations of the foam material may be used. E.g. a grid structure may be used having a rectangular mesh.
Circular voids could also be used.
