Definitions

  • This invention relates to facing blocks of the type used in the construction of buildings and structures to provide natural stone effects generally on the external surfaces of the building or structure but which can also be used internally as décor finishes or feature claddings or coverings such as fireplace surrounds etc.
  • the set pieces of stone may be treated to improve or change the natural appearance of the stone, for example by staining, polishing or varnishing or it can be worked with tools which is generally known as dressing the stone.
  • the stone may be presented as It appears naturally, or undressed.
  • other materials may be set as required.
  • the simple shape of these stone faced blocks render them far easier to assemble into building structures than randomly shaped stone pieces.
  • the blocks can be assembled using all-weather techniques conventionally used for plain concrete block and brick building providing a simple and cost effective route to an attractive, traditional or modern decorative external wall surface.
  • a problem addressed is the additional weight added to a typical sized concrete block by the inclusion of stone pieces on the surface. Often the most commonly used sizes of blocks are too heavy for a single person to handle and position safely. Also, whilst the stone pieces on the surface of an individual block can be randomly spaced to provide a realistic stone built effect, the rectangular outline of the individual blocks can sometimes be seen to disrupt the random appearance on a completed surface comprising a number of the blocks.
  • the problem is addressed by providing a decorative building block comprising; a supportive load bearing body having set into at least one surface a decorative arrangement of mineral pieces wherein the load bearing body comprises a mixture of a cement and lightweight aggregates.
  • the present invention provides a block which enables a builder to more quickly and cost effectively construct a wall or structure with a finished appearance.
  • the invention is applicable to regular weight blocks and the lightweight blocks described in the Applicant's earlier patent GB 2 356 875 .
  • a decorative building block comprising; a supportive load bearing body, a layer of pointing mix set onto at least one external surface of the load bearing body and a decorative arrangement of mineral pieces set into the aforesaid external surface or surfaces.
  • a further step d) Involves cleaning the exposed surfaces of the mineral pieces to remove any excess pointing mix.
  • a preferred, yet optional cleaning method is brushing the decorative surface with a steel brush.
  • the mineral pieces may be dressed or treated as previously described to change their cosmetic appearance.
  • the pointing mixture is added to a surface of the cementitious mix while the load bearing body is still pliable. This has the advantage that the mineral pieces can be more deeply set into the surface, creating a more convincing three dimensional appearance of the completed block.
  • the pointing mixture may be of any known composition including but not strictly limited to sand mortars of varying colours; sharp sand, lime and grit.
  • composition of the cementitious mixture Is immaterial it can be any mixture known to the construction industry used to produce load bearing blocks.
  • the mixture may comprise a lightweight composite such as that described in the Applicant's earlier patent GB 2 356 875 and protected by the Applicant's trade mark TRAD-LITE ®.
  • the mould is conveniently, but not essentially comprised of a flexible, peelable material such as rubber.
  • the completed blocks may be assembled into a building structure by placing them adjacent one another with their decorative surfaces in alignment and by bonding the adjoining edges of the blocks with a bonding agent, for example but not strictly limited to mortar, or a resin.
  • a bonding agent for example but not strictly limited to mortar, or a resin.
  • the mould and block may, optionally, be provided with a peripheral lip to enable the decorative pieces to overhang the main body of the block and allow overhanging mineral pieces on adjacent blocks to be interleaved and provide a more random appearance in a finished structure built from the blocks.
  • the lip may have slightly larger dimensions than stated in our earlier GB patent GB 2 356 875 .
  • the lip may extend by anything from about 1mm to about 10mm beyond the load bearing body of the block.
  • the lip may comprise solely of pointing mixture and mineral pieces, the cementitious mix being confined to the main load bearing body of the block.
  • the lip on the mould allows a decorative surface which extends slightly beyond the perimeter of the load bearing body, this enables some of the set decorative mineral pieces to be positioned to overhang the edge of the load bearing block.
  • the overhanging mineral pieces can be aligned to fit into gaps on adjacent blocks. This results in a less apparent demarcation between blocks and a more random overall pattern of pieces on the completed wall surface.
  • the mould for the load bearing body is provided with a peripheral lip sufficiently deep to receive pieces of mineral to be used In the decorative facing. Whilst the peripheral lip is conveniently provided about a top surface of the block, it may be provided in a plane below that surface.
  • the block may, optionally, be provided with a frog incorporated around the periphery of the block.
  • the frog is incorporated around the periphery of the block between the outer facing decorative surface and the inner-facing surface of the block.
  • the frog is provided in the form of a groove of any suitable cross section such as a V or rectangle or square, preferably the cross-section is arcuate, most preferably semi-circular. Whilst the frog may be incorporated at any position between the decorative surface and the inner surface, it is preferably positioned about midway between the two surfaces.
  • the width and depth of the frog are not critical but they are preferably of the order of a few centimetres for the width and a few millimetres for the depth.
  • the frog provides a keying surface for the mortar when the blocks are laid as the blocks have to be laid with reduced bed and perpendicular joints of ideally 5mm but between 2mm and 8mm (normally 10mm) to achieve the best results.
  • the lip and frog can be incorporated when the block is moulded.
  • the blocks can be moulded in a rubber or similar flexible mould, which can be peeled away from the set block without risk of damage.
  • load-bearing blocks In order to meet the requirements of British Standards and any other relevant regulations load-bearing blocks must be able to withstand any specified loads.
  • load-bearing body Varying proportions of cement and aggregates (both lighter and normal weight) may be used in the body, provided that set moulding meets the specified strength criteria.
  • load bearing a block In order to be considered load bearing a block should be able to withstand a load of at least about 7N/mm 2 .
  • the decorative arrangement of mineral pieces may comprise pieces of flint, sandstone, limestone, pebbles, cobbles or any similar attractive naturally occurring or other artificial materials such as bottles etc., stone or mineral.
  • the pieces may be whole, particularly in the case of cobbles and pebbles, or cut and may be dressed or undressed.
  • the decorative arrangement may be applied to two or more adjacent surfaces of the block to provide a corner, two sided, edge or end block.
  • a block according to the present invention comprises a load bearing body 1 onto a surface of which is provided a decorative facing 2 comprising a number of flint or similar mineral pieces 3.
  • the decorative pieces are set into an outermost layer of pointing mixture 6 of the block.
  • the mould has a peripheral lip 4 extending from the upper surface into which pieces of flint or similar mineral pieces 3 can extend.
  • Figure 2 shows the block of Figure 1 in cross section. As can be seen, the decorative pieces are set deeply into the pointing mixture layer 6 and through into the top most surface of the load bearing body 1 which comprises the cementitious mixture.
  • Figure 3 shows the top face of two facing blocks according to the present invention. It can be seen that the hand set mineral pieces 3 provide a slightly irregular shaped periphery to the top surface of the facing block. Blocks can be then matched such that protrusions from one block can be aligned with indentations on adjacent blocks. As can be seen from Figure 3b this results in a far more random surface pattern when the blocks are laid together a long a join 7. The join may be sealed by the provision of a bonding agent along the join 7.
  • the block shown in Figures 4 and 5 is in most respects the same as that shown in Figures 1 and 2 but is distinguished by the provision of a rebate 8 or "half rabbit" which serves, when the edges of two blocks are abutted in a building structure, to create a channel to facilitate the insertion of pointing material to further improve and disguise the joins.
  • the rebate is shown on an upper edge surface of the lip but may be provided on an outer edge surface of the lip.
  • the cross section of the rebate shown is rectangular but may have any other suitably shaped cross section for example, but not strictly limited to; wholly or partly wedge shaped or wholly or partly curved.
