DESCRIPTION:
BRIEF SUMMARY
The present invention relates to form work partitioning systems for making bricks or blocks in situ, and in particular, to an improved form work partitioning system which combines the advantages of conventionally laid blocks and the advantages of cast walls.
BACKGROUND ART
In the constructioning industry, the cost and availability of kiln-fired bricks for construction purposes has often necessitated the use of other building materials such as sandstone blocks, wood, fibrous-cement panelling, metal panelling and so on. One form of building material which is both inexpensive and readily available is mud bricks. Another form is cement stabilized earth walls and rammed earth walls.
In the form of construction using mud bricks or blocks, the bricks are usually formed in a mould and are then allowed to dry in the sun until they have hardened to a state ready for construction. The mud-bricks or blocks are then used in a conventional manner and are usually mortared together to form a wall or the like. Such a construction method is very time consuming as the construction and the making of the bricks or blocks are separate procedures.
In the other forms of construction such as cement stabilized earth walls and rammed earth walls, the mud and cement material is cast as a hole by filling prefabricated form work with the suitably hardenable material. One problem with such a structure is that as the material dries and thereby hardens, the material has a tendancy to shrink and cause cracks and therefore shrinkage cracks are a major problem.
OBJECT OF THE INVENTION
It is an object of the present invention to provide an improved form work partitioning system for use in the construction industry which substantially overcomes or ameliorates the abovementioned disadvantages.
DISCLOSURE OF THE INVENTION
According to one aspect of the present invention there is disclosed a framework partitioning system comprising a plurality of vertical formboards in a pair of opposed rows, each said formboard being connected to and spaced apart from adjacent said formboards by one of a plurality of partitions, each said partition being attached to both said opposed rows thereby spacing the opposed rows apart and forming a mould between a pair of adjacent partitions and a pair of opposed formboards, said partitioning system being used to cast blocks in a course by filling the moulds with a hardenable material whilst the said partitioning system is placed above the previously moulded course of blocks, with the lower edges of said formboards overhanging the previously moulded course of blocks, wherein said partitions comprise a partition body which is substantially wider in the center than at the either of the vertical edges and is slightly wider at the upper edge than the lower edge.
According to another aspect of the present invention there is disclosed a method of using the abovementioned partitioning system.
BRIEF DESCRIPTIONS OF THE DRAWINGS
Some embodiments of the present invention will now be described with reference to the drawings in which:
FIG. 1 is a schematic perspective view of a partitioning system of one embodiment in use for construction of blocks in situ on a wall being constructed,
FIG. 2 is a perspective view of a partition of one embodiment for use in the system of FIG. 1,
FIG. 3 is a perspective view of a form board of one embodiment to use with the partition of FIG. 2,
FIG. 4 is a partial plan view showing the connection of the partition of FIG. 2 and two adjacent form boards of FIG. 3,
FIG. 5 is a plan view of the partitioning system of FIG. 1,
FIG. 6 is a perspective view of a mould of a second embodiment of a partitioning system showing a formwork mould,
FIG. 7 is a plan view of the mould of FIG. 6, and
FIG. 8 is an end elevational view of the mould of FIG. 6.
BEST MODE OF CARRYING OUT THE INVENTION
As seen in the drawings, the partitioning system is use to construct walls or like structures by forming blocks of hardenable material in situ. A foundation 1 is laid onto which the construction is to be positio
