Abstract
Description
- The present invention relates to masonry building blocks, and in particular to a type of building block comprising a stone veneer.
- The masonry wall is a very widely used wall construction. Typically, a masonry wall is constructed of a plurality of building blocks, laid in courses and joined together by mortar. Examples of building blocks include, but are not limited to: a stone, a cut stone having flat surfaces, a brick, a breeze block, a concrete block, a clay block and the like.
- Many buildings are constructed using a cavity wall design, where the building comprises inner and outer leaves. In such construction, the inner leaf is the load carrying structure, with the outer leaf being specified for weather proofing and appearance. Where a masonry appearance is desired, the typical choices are stone, brick or rendered concrete block.
- Stone is generally regarded as the most desirable material in terms of appearance and hence property value. However, stone is costly as a material, and building with stone is slower than with blocks or bricks due to the irregular shape of undressed stone.
- Various systems for creating the appearance of a wall that is constructed of stone have been proposed. For example,
US1070281 describes a system of blocks to which stone veneers may be attached using a dry mechanical connection. - It is well known that novel systems of construction are slow to be taken up by the building industry.
- It would therefore be desirable to provide a building block which provides the appearance of a stone construction of a wall that is constructed of such building blocks, yet which does not require any new building techniques to be learned or adopted.
- According to the invention there is provided a building block comprising a cast concrete component and a stone component, and at least one attachment element, wherein the at least one attachment element is attached to the stone component, and wherein the at least one attachment element is secured to the stone component by adhesive, and wherein the stone component is bonded to the concrete component.
- The at least one attachment element may comprise a dowel and one end of the dowel may be located in a hole in the stone component.
- The at least one dowel may be of metal, such as steel, or a plastics material for example.
- The stone component may be bonded to the concrete component by a cement bond, or an adhesive bond.
- The density of the cast concrete component may be in the range of 1900kg/m3 to 2100kg/ m3. The cast concrete component may have a density falling outwit the aforementioned range so long as the resulting cast concrete component is capable of being used to build a wall following the steps of the third aspect of the invention.
- The stone component may be longer than the concrete component.
- According to a second aspect of the invention there is provided a process for forming a building block of the first aspect of the invention, the process comprising the steps of:
- providing a mould;
- positioning the stone component of the building block at the bottom of the mould, wherein the at least one attachment element is attached to the stone component and extends into the mould;
- pouring concrete into the mould;
- allowing the concrete to cure.
- The mould may be shorter in length than the stone component.
- According to a third aspect of the invention there is provided a wall comprising:
- a first plurality of building blocks according to the first aspect of the invention on a first bed of mortar with mortar between adjacent vertical faces of the plurality of building blocks; and
- a second plurality of building blocks according to the first aspect of the invention on a second bed of mortar on an upper surface of the first plurality of building blocks with mortar between adjacent vertical faces of the plurality of building blocks.
- Advantageously, the width of the bed of mortar corresponds to the width of the concrete component of the building block.
- Advantageously, the mortar between the vertical faces of the building blocks is aligned substantially with end faces of the concrete components of the adjacent building block.
- The mortar located between the concrete components of adjacent building blocks may be a sand cement mortar.
- Preferably, the wall further comprises lime mortar in the spaces between the stone components of the building blocks forming the wall.
- The wall may comprise a corner and the corner may include a building block having a stone component that is longer than the concrete component thereof. At such a corner, the stone component of one building block may overlap the stone component of an adjacent building block. Lime putty may be placed between the stone components of adjacent blocks where the stone components overlap.
- In the Drawings, which illustrate preferred embodiments of the invention:
-
Figure 1 is a schematic plan view of a building block; -
Figure 2 is an exploded view of a detail of the building block illustratedFigure 1 ; -
Figure 3 is a plan view of the building bock illustrated inFigure 1 ; -
Figure 4 is an end view of the building block illustrated inFigures 1 and3 ; -
Figure 5 is a plan view of another configuration of a building block; -
Figure 6 is an end view of the building block illustrated inFigure 5 ; -
Figure 7 is an end view of part of a wall constructed using the building blocks illustrated inFigures 1 to 4 ; -
Figure 8 is a plan view of a wall constructed using the building block illustrated inFigures 5 and 6 ; and -
Figure 9 presents plan and side views of a mould used to form the blocks illustrated inFigures 1 to 4 ; and -
Figure 10 presents plan and side views of a mould used to form the blocks illustrated inFigures 5 and 6 . - Referring now to
Figures 1 to 4 , abuilding block 1 comprises aconcrete component 2 and astone component 3. In the illustrated embodiment the concrete component is approximately 100mm deep and the stone component is approximately 20mm deep. Thewhole building block 1 is approximately 440mm in length, which is the length of a standard concrete building block. - The building block includes
steel dowels 4. In the illustrated embodiment two steel dowels are provided. The steel dowels are situated inwardly ofrespective end faces block 1. For the 440mm block illustrated the dowels are situated approximately 150mm inward from the respective end faces. - Referring specifically to
Figure 2 , it can be seen that thestone component 3 is provided with ahole 5 shaped and dimensioned to receive one end of thesteel dowel 4. Thesteel dowel 4 is secured in thehole 5 with a stone adhesive. - The
block 1 is formed by casting with a poured concrete mix. Thestone component 3, with thesteel dowels 4 glued in place in theholes 5, is placed in the bottom of a mould. Concrete is then poured into the mould to the required depth (100mm in the illustrated embodiment). The concrete bonds to thesurface 3a of the stone component and to thesteel dowels 4. -
Figures 5 and 6 illustrate a corner block 1' in which the stone component 3' extends beyond theend face 2a' of the concrete component 2'. This provides arear face region 3a' of the stone component 3', the purpose of which is to cover theend face 2a of theblock 1 in a wall construction.Figure 8 illustrates the corner block 1' in such a wall construction. -
Figure 7 illustrates a wall comprising a first course ofbuilding blocks 1 and a second course ofbuilding blocks 1 with a layer of mortar 7 therebetween. The layer of mortar 7 covers only the concrete part of the building block. The mortar 7 is a sand and cement mortar, which is the appropriate type of mortar for bonding two concrete components together. However, a sand and cement mortar is not appropriate for use between thestone components 3 of theblock 1. During initial construction of a wall frombuilding blocks 1, theregion 8 between the stone components of thebuilding blocks 1 is left unfilled. When the wall is built, theregions 8 are pointed to give a weather proof and aesthetically pleasing finish. Theregions 8 are pointed with a lime and sand mortar. A lime and sand mortar is more flexible than a sand and cement mortar. The lime and sand mortar allows differences in expansion and contraction with temperature (concrete and stone have different coefficients of thermal expansion and contraction) to be taken up. Furthermore, moisture taken up by the stone during rain events for example, may be dissipated through the lime and sand mortar, whereas sand and cement mortars tend to trap moisture. -
Figure 8 illustrates a wall including a corner constructed ofbuilding blocks 1 ofFigures 1 to 4 and building blocks 1' ofFigures 5 and 6 . As will be appreciated by the skilled person, to form the corner, part of therear face 2c of theconcrete component 2 ofblock 1 overlaps theend face 2a' of the concert part 2' of block 1'. A layer ofmortar 8 is located between theend face 2a' and therear face 2c. Typically, themortar 8 would be placed on theend face 2a', with therear face 2c being presented up to and pressed against themortar 8 by the builder laying the blocks. The stone component 3' is shaped and dimensioned so that the whole end face of theblock 1 is overlapped. A small amount of lime putty is placed between therear face part 3a' and theend face 2a ofblock 1. Theend face 3c of thestone component 3 is also covered by the stone component 3' of block 1'. Where stone overlaps stone, the stone is wetted prior to application of lime putty. The lime putty creates adhesion between the stone component 3' of block 1' and the both the concrete andstone components block 1. - The skilled person will appreciate that in alternate courses of a wall, the position of the
blocks 1 and 1' will be exchanged to create an interlocked corner joint. -
Figures 9 and10 illustrate moulding equipment used for creating thebuilding blocks 1, 1'. - The
mould 11 ofFigure 9 sits on top of thestone component 3, to which thedowels 4 have been attached. Themould 11 comprisesside walls 11a and endwalls 11b. The internal shape and dimensions of themould 11 correspond to the external shape and dimensions of thestone component 3. - The
mould 12 ofFigure 10 sits on top of the stone component 3', to which the dowels 4' have been attached. Themould 12 comprisesside walls 12a, afirst end wall 12b and asecond end wall 12b'. Theside walls 12a are shorter than the stone component 3' so that concrete is poured in the mould over only a part of the stone component. Themould 12 sits over a part of the stone component 3'. The internal width of the mould corresponds to the external width of the stone component and the internal surface of theend wall 12 is aligned with the external edge of the stone component 3'. - With the
stone component 3, 3' aligned with themould - The resulting
building blocks 1, 1' provide a stone face with much reduced cost when compared to a solid stone block of the same size.
