ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The following invention relates to a suspended brick wall lintel system. More particularly, though not exclusively, the invention relates to a system used to support brick veneer walls off the ground in the construction of brick veneer dwellings without the requirement for conventional concrete foundations, footings or a concrete slab poured directly onto the ground.
2. State of the Art
Known method of constructing full brick and brick veneer dwellings require the wall systems to come into intimate contact with the ground. Thus white ant and drainage problems prevail.
The construction of such dwellings is a time consuming process which is labour intensive and requires special tools and skills.
Also, known construction methods involve a high level of distance to the natural ground.
SUMMARY OF THE INVENTION
It is the object of the present invention to overcome or substantially ameliorate the above disadvantages and/or more generally to provide an improved building system.
There is disclosed herein a support structure for a building, comprising:
a pair of steel piers embedded into or supported upon a ground surface so as to extend upwardly therefrom,
a wall support lintel secured to each pier so as to extend substantially horizontally therebetween, and
a respective floor support member secured to each pier.
Preferably the wall support lintel is secured to each pier by means of a lintel support bracket which is vertically, adjustably affixed to each pier.
Preferably the floor support comprises a bracket which is vertically, adjustably affixed to the pier above the wall lintel support bracket.
Preferably the piers are either the screw, driven or concrete footing supported type.
The piers can have a circular or square cross section or cross section of any shape.
Preferably the lintel support bracket comprises a ledge upon which the wall support lintel rests.
Preferably the lintel support bracket comprises a latching bar and each wall support lintel comprises a lip engageable with the bar so as to laterly restrain the wall support lintel.
Preferably the lintel support bracket and floor support bracket comprise hollow members adapted to surround the pier.
Preferably the lintel support bracket and floor support bracket comprise laterally projecting tapped apertures through which a fastener extends, the threaded fastener, upon rotation thereof, being adapted to bear against the pier so as to secure the respective bracket thereto. Typically in this operation, the pier is deformed by the threaded fastener.
There is further disclosed herein a wall lintel support bracket comprising a hollow member adapted to surround a pier, the bracket further comprising a ledge adapted to support a wall lintel and a latching bar adapted to engage with the wall lintels so as to restrain lateral movement thereof.
In a preferred embodiment, each lintel support bracket has associated therewith an adjustment plate adapted to secure the wall support lintel to the support bracket.
Preferably, the adjustment plate comprises a slot through which a threaded fastener passing through the lintel support bracket can pass so as to allow positional adjustment of the adjustment plate with respect to the lintel support bracket.
Preferably, the slot extends in a direction substantially perpendicular to the longitudinal extent of the wall support lintel.
Preferably, the lintel support bracket is affixed to the respective steel pier by means of U-bolts or the like.
Preferably, a shear stud extends from the lintel support bracket through a hole in the steel pier.
There is further disclosed herein a support structure for a building comprising:
a pair of steel piers embedded into or supported upon a ground surface so as to extend upwardly therefrom,
a wall support lintel secured to each pier so as to extend substantially horizontally therebetween, the wall support lintel including a ledge upon which a wall is supported, the ledge being positioned upon each pier so as to bear downwardly thereon directly from above.
Preferably an adjustable cap bracket is affixed to an upper end portion of each pier, the adjustable cap bracket supporting said wall support lintel.
Preferably, the adjustable cap bracket is designed to enable height adjustment of the wall support lintel.
Preferably, the adjustable cap bracket is secured to the wall support lintel by means of a retaining bracket or brackets.
The above form of the invention in which the wall support lintel is positioned directly upon each pier is particularly suitable for application is existing dwellings about which a new brick veneer wall is to be installed. That is, each pier does not require a floor support member as the floor is already supported by existing structural elements. As an advantage of bearing the load of the wall directly upon an upper end of each pier, no shear forces need be withstood by the adjustable cap bracket. That is, the adjustable cap bracket can bear directly down upon an upper end of the pier and this increases the load carrying capacity of the braket. As a result, the disclosed structure can support the weight of two storys of bricks, rather than a single story of bricks, the load of which might be sustained by the support store described earlier.
There is further disclosed herein a method of supporting a building, the method comprising:
embedding or otherwise supporting into or upon a ground surface a pair of steel piers so as to extend upwardly therefrom,
securing a wall support lintel to each pier so as to extend substantially horizontally therebetween, and
securing a floor support member to each pier so as to support a floor.
There is still further disclosed herein a method of supporting a wall about an existing building framework, the method comprising:
embedding into or supporting upon a ground surface a pair of steel piers so as to extend upwardly therefrom,
positioning a wall support lintel upon each pier so as to extend substantially horizontally therebetween, the wall support lintel including a ledge, the ledge being positioned upon each pier so as to bear downwardly thereon directly from above, and
erecting a wall upon said ledge.
