DESCRIPTION:

BRIEF SUMMARY
This Invention relates to a method of constructing a brick wall, and to a wall when constructed by that method. In particular, the invention is directed to a method for constructing brick cladding for an existing structure, although the invention is not limited thereto. building block whether constructed of clay, cementitious material, or other material. The term "pier" as used in this specification is intended to include a post, pile, discrete footing, or similar support structure.


BACKGROUND ART

The advantages of brick walls for houses and other buildings have long been recognised. Many owners of buildings having timber walls often wish to construct brick outer walls (or "cladding") for the building. However, known brick cladding methods are time consuming, labour intensive, and relatively expensive.
Normally, it is necessary to dig a trench around the building, close to the existing walls, in order to provide footings for the brick wall to be erected. Since water pipes, gas and/or electricity lines, telephone lines and other utilities are often located underground leading to the building, the construction of those footing trench requires the interruption of the services. Moreover, these service lines may be inadvertently cut or ruptured when digging the trench.
The footing trench also interferes with access to the building.
Another problem associated with such footing trenches is the weakening or removal of support for the existing building.
Trench footings are not recommended for reactive soils, such as clay, as the movement of the soil with changing environmental conditions causes movement of the foundations, and hence the brick wall supported by the foundations. This leads to cracking, and possible failure of the brick wall.
It is an object of the present invention to provide an improved method of constructing a brick wall, particularly but not solely for use as a cladding wall, which overcomes or ameliorates the abovedescribed disadvantages, or which at least provides the builder with a useful choice.


SUMMARY OF THE INVENTION

In one broad form, the present invention provides a method of forming a brick cladding wall for a preexisting building, comprising the steps of building, piers and supported thereon, and a wall.
According to this invention, the brick wall is supported on the spaced piers. Normally, when erecting a wall on piers, it is necessary to provide a supporting member, such as a bond beam or lintel to support the wall, between the piers. However, it has been found that a support structure can be formed from two or more lowermost courses of bricks. An elongate reinforcing member, such as a steel reinforcing rod, is located between adjacent lower courses. Typically, opposed open longitudinal channels are formed in the bricks of adjacent lowermost courses, and the reinforcing rod is located within the composite bore formed by the opposing channels. The remainder of the bore is filled with grout. In this manner, the reinforced corefilled courses of bricks form an effective bond beam which spans between the piers and supports the brick wall.
Typically, the bricks in the lower courses have a larger width than the bricks in the higher courses.
The abovedescribed method is particularly suitable for constructing brick cladding walls for existing buildings. Instead of digging a trench around the building to provide the wall footings, it is only necessary to sink piers at spaced locations around the building, thereby minimising interference or disruption to building access and services. The piers are preferably smooth sided to eliminate or minimise any movement on the piers in response to soil movement. Thus, this method of wall construction is particularly suitable for use in reactive soils.
In another form, the invention provides a method of forming a brick wall, comprising the steps of piers and supported thereon, the support beam being formed from a plurality of courses of bricks having a longitudinally extending steel reinforced cementitious core, and
