Abstract
ABSTRACT
Current wall building methods using modular blocks generally employ materials such as concrete, clay, stone,mud and glass, erected with the vertical joints staggered, and relying upon a mortar or other adhesive to bind adjoining surfaces to provide the desired structural lateral stability.
The degree of verticality and flatness of the finished wall is however in direct proportion to the ability of the erector to lay true and even beds, and to continually "adjust" the separate units as the wall grows.
In this invention the modular block is rigid insulation, with various holes running vertically through the block from top to bottom. The block may be manufactured using either extrusion or casting methods, either of which will provide a perfectly true unit, with all sides flat and of exact dimension.
The block, being lighter in weight than conventional block materials, is much larger in size, and is erected in stretcher bond, but with all joints DRY. Lateral stability of the wall is effected by the use of pegs of similar rigid insulation, which are driven through the holes of the blocks vertically,each peg penetrating 50% into each of the blocks above and below.
The wall system of building these blocks relies upon friction for basic strength, together with a staggered horizontal and vertical bond with the pegs providing a resistance against bending.
The pegs offer also the ability to provide an absolutely flat interior and exterior surface of the wall, since each peg locates the blocks above each other with absolute accuracy.
The wall system offers also the advantage of being fast in erection time, and can be accomplished without the use of skilled labour.
The block and peg sizes and shapes will be adjusted to suit the heights of walls required, and the desired friction and bending moments required.

Description
`f'`7 SPECIFICATION
his invention relates to a wall building system which uses rigid insuiation building blocks and pegs in unison.
Traditional building systems using blocks manufactured from mud,cement,stone have been available in the building industry throughout time, each relying upon some form of adhesive or ~inder such as cement mortar to provide structural stability.
Disadvantages with these systems are many, and include a) small unit size related to the weight which can comfortably be handled by one person, resulting in lengthy time of erection b) the ~wet~ system, using mortar requires a curing time before structural strength is reached, resulting in lengthy time of erection c) the 'wet" sy~tem requires a total reliance upon experienced workmanship to produce a wall which is vertical and straight.
d) the "wet" system produces mortar joints which tend to telegraph through the eventual wall finish which may be applied with too thin a coat.
e~ the "wet" system produces mortar joints which may have air leakage owing to either the poor mortar laying or the rough and uneven block.
In this invention a lightweight rigid insulation has been selected, thereby permitting a building block to be much larger than normal,manufactured to exact physical dimensions and with completely flat and smooth surfaces. The blocks will be manufactured with a pattern of vertical holes running through them from top to bottom, such holes being used for three functions,viz - locating blocks accurately above each other using pegs through the holes - providing lateral stability of the wall through friction between the blocks and the pegs,and through vertical bonding of the pegs, producing a vertical truss effect. (see sketch 3B) - providing service conduits through the blocks by the use of unpegged holes The pegs, manufactured from the same lightweight rigid insulation, will be sized in length to suit the structural stability required, and in cross section to be a tight fit to the type of holes provided in the building blocks.
This DRY system of building BLOCXS and PEGS of RIGI; INSULATION
has many advantages:
- faster erection time using larger unit sizes - faster erection time by the elimination of curing of cement mortar - elimination of the service chase or groove routering process prior to application ~
interior finish - completed wall is straight and vertical - completed wall is completely flat and smooth \

2~ 7 - completed wall is virtually air leak proof since all blocks are drawn tightly together by the driven pegs DRAWING #1 is an aerial sketch which indicates the entire building system as it would be on a building site, and indicates the following components of the system:
_ A) BUILDING BLOCKS of rigid insulation B) BUILDING PEGS of rigid insulation C) HOLES in blocks D) FLOOR PANELS/ROOF PANELS of rigid insulation E) GRADE BEAM of rigid insulation F) Drilled holes in floor panels of rigid insulation G) Augered holes in ground, filled with concrete Items D),F) and G) do NOT form a part of this invention, and can be replaced by conventional forms of construction such as reinforced concrete floor panels and conventional concrete foundation walls. Item D) may be the subject of a future patent application.
DRAWING #2 indicates one typical block and peg, where the "front"
elevation is in fact the plan of a block from above, and the "side" elevation is in fact the inner or outer face of the block when it is erected in place. The PEG,B) is shown as a round peg of 1.5" diameter and 24" long. It is shown with a 50% entry into the block. The peg can be of other cross sectional shapes and sizes depending upon the desired structural stability and strength required. The peg can also be of other lengths, depending upon the sizes of blocks and the desired depth of entry required, which can be up to 100% The peg will never be longer than twice the height of the block.
The density of insulation to be used in the manufacture of the blocks and pegs will have a direct effect on the shapes and sizes to be chosen, since the strength offered by the system stems from the frictional qualitie~ of the insulating material, and of course friction is directly related to area of surfaces in contact with each other.
DRAWING #3 is a typical SECTION through the exterior wall of the system. It indicates pegs B) driven into place, 50% into each of the blocks above and below. The HOLES C) in the ~locks are shown also in the GRADE BEAM E), which is in effect a typical block where the holes penetrate only the top 50% of the unit. Vents G) can also be provided in the GRADE BEAM E) where required, if timber floors are used in conjunction with the system. The GRADE
BEAM's holes may also penetrate a full 100% through the beam if required for additional structural stability.
The CORBELLED ROOF BLOCKS H) do not form part of this invention and may be the subject of a future patent application.
DRAWING #4 is a part WALL ELEVATION of the typical wall system, Z~ 7 and indicates the BLOCKS A) in stretcher bond overlapping e~ch block above and below by 5n% of it~ length. With the HOLES C) in the locations shown in DRAWING #2, this overlap can be reduced to 4.5"if required, and of course other HOLE locations will produce lesser overlaps if necessary. PEGS B) are indicated as being driven 50% into the BLOCKS A) above and below, producing a vertical stretcher bond pattern which provides a distribution of structural stability across the entire wall surface. This structural strength may be increased by an appropriate increase in the length of the PEGS and depth of penetration up to 100%.
DRAWING #5 is a series of freehand sketches which indicate the following:
SKETCH 1 indicates the wooden mallet and puncher to be used for driving the pegs into the blocks to the required depth.
The diameter of the puncher will be fractionally less than that of the peg, and its length adjusted to the depth of entry required.
SKETCH 2 indicates the typical block wall construction problems of verticality and flatness as compared to this invention with its locating pegs.
SKETCH 3 indicates the typical block wall construction problems using the "dry" method, ie without the use of mortar, and compares it with this invention. It should be noted here that a conventional concrete block wall, constructed using mortar ~oints, has little resi~tance against overturning until it is laterally supported at the top by other means.
SXETCH 4 indicates how the frictional qualities of the rigid insulation permit the driven pegs to force the blocks tightly together, and prevent eventual separation.
INTERIOR AND EXTERIOR FINISHES;
This system of wall erection produces a flat surface to receive both exterior and interior aesthetic finishe~ which are typical in the industry.
An exterior conventional system of waterproof ~tucco on fibreglass mesh will be an ideal and economical finish for most situations, and cementitious plaster with vapour barrier additive or gypsumboard adhered with a vapour barrier adhesive would be ssuitable interior finishes.
Other finishes such as wood lining, aluminum siding, brick, stone etc. are all acceptable to the system, requiring only adaptation of detail.

Claims (3)
1) nails - which secure by friction
2) studs - which provide bending moment stability by their continuity and longitudinal tensile strength.
3) dowels - which locate "pieces" accurately above and/or adjacent to each other.
Rigid insulation, manufactured in various densities, has physical properties which differ from other materials, in that it can be A) manufactured precisely to particular physical dimensions B) manufactured to perfectly flat and smooth surfaces C) manufactured to substantial compressive strength depending upon the density of the insulation D) manufactured to substantial tensile strength depending upon density of the insulation In addition, rigid insulation has a unique frictional quality, in that, when two perfectly smooth surfaces are pressed firmly together, friction prevents either from sliding over the other.
This invention does therefore permit building blocks, manufactured from rigid insulation,and perforated with various holes from top to bottom, to be used, in conjunction with pegs (dowels), manufactured from rigid insulation, to construct a wall which has structural stability and a high degree of accuracy in flatness and verticality, without the use of any adhesive or mortar bed to assist, and relying completely upon such frictional characteristics of the insulation.
The vertical holes in the building blocks double as service ducts for electrical and other services, but their main function is structural, in that they permit forced entry of the pegs, which are manufactured specifically to a tight fit, and to a length which provides a 50% entry into the blocks above and below each other, thus providing a VERTICAL PEG BOND. This vertical peg bond will be increased up to a full 100% entry into the blocks above and below each other when additional structural stability is required.
In summarizing, this invention claims:
A) structural stability by friction using rigid insulation B) structural stability by vertical bond of pegs of rigid insulation to blocks of the same material C) accuracy in verticality and flatness of the wall by the use of locating pegs and blocks of rigid insulation D) capability of accurate erection using unskilled labour
