Definitions

  • This invention relates to building blocks, to a method of constructing a building, a method of constructing a building block and an assembly of building blocks.
  • a characteristic of existing concrete blocks is that they are very porous and it is considered that this is an economically useful characteristic of concrete blocks as currently manufactured because, in order for these to be economic, they are formed using a very dry concrete mix so that their form is established within a mould in such a way that they can then be very quickly removed and left to then set separate from a mould.
  • a conventional concrete block formed in this way is also conventionally formed with one or more hollow centres with an open top and bottom.
  • a further difficulty then arises because of the porous nature of the block and further processes, perhaps for instance, rendering of the face of any wall which is then more often needed to assist in ensuring a wall will provide a sufficient protective wall for purposes of a building.
  • An object of this invention is to propose a block which can be used to construct masonry walls, as well as a wall as such and a method of building all of which facilitate a cost saving at least in the eventual product, for instance when using a block, and that such savings can be achieved while at least maintaining a construction that will meet required building standards.
  • a composite masonry building block which has an outer facing material that is formed as a wet cast cement-based material based material and has a core of a material or materials which are of less density than the outer wet cast cement based material.
  • the wet cast cement based material is a mixture of an extender and a binder.
  • wet cast cement based material is a mixture of an extender such as sand and a binder such as a cement such as Portland cement.
  • An advantage of this arrangement is that such a block can, by reason of the nature of wet cast cement material have an outer surface which is of low or negligible porosity and it also can be made to a high degree of accuracy.
  • wet cast cement based material as a material can also be therefore implicitly strong in the context of masonry products so that instead of using a mortar bed for joining one block upon another, there can now be an adhesive.
  • a core or body of the block by being faced by the wet cast cement based material can be protected and therefore the type of material that can then be used allows for a large block in physical size which nonetheless does not then weigh a proportionately significantly greater weight.
  • a desirable weight considering the lifting capacity of a worker might be up to let us say typically approximately 14 kg, so that by reducing in the body, the density of the materials, we then have the possibility of a much larger block for the same all up weight.
  • the material of lighter density be expanded plastics material with a binder.
  • such a binder can be a wet cast cement based material that then would be expected to be compatible with the outer surface material.
  • a core which is comprised of at least in the main, by volume, expanded polystyrene foam and a binder selected from materials where these are compatible both with expanded polystyrene foam and the outer wet cast cement based material whether this is a facing on one face only or on a back and front face or as fully surrounding material.
  • a glue or adhesive material is intended to be a material that of itself does not need to and does in fact not provide significant bulk, one can afford to have a more expensive material for an effective bonding which then can provide significant adhesion between respective matching surfaces.
  • the block has an overall appropriate shape which can include curved surfaces but in a preferred example is of rectangular proportions in which there are two opposite faces providing an outer face and an inner face, two end faces and a top and bottom face.
  • one or more projections in a one of the faces of the block and one more cavities corresponding in being a matching shape and position relative to the matching shapes in the opposed face within a second oppositely positioned face of the block are further provided.
  • projections on an upper face that are spaced apart an equal distance and such that such projections can be used by matching cavities by a block which is either aligned at right angles to the first said block or overlaps the said block only by a proportion of the total length of the block.
  • this matching would also be matched by appropriate cavity shapes within an underneath side of a block.
  • each projection projects above an otherwise generally planar shape of the face and has a shape in cross section which will allow for compatibility with an underneath cavity shape, whether that cavity shape is positioned with the respective block aligned or at right angles to the projection.
  • each projection in preference is of a frusto-conical shape in one case or part of a sphere in another.
  • the conical shape is chosen so that in a practical sense, when one block is located over another, an edge of an upper block can be first rested on the top of the underlying block and the top block can be lowered pivotally on its resting end so that any cavity then will receive into itself the projection without snaring an edge and perhaps breaking off a portion of the projection.
  • the sides of the projection and the matching shape of the cavity includes the inclined sides.
  • this can be chosen to be of either low or negligible porosity, and can be very strong and accurately sized in a way that such accuracy can be maintained through the curing process for subsequent reliance then when on a building.
  • the block is made by having a mould in which the wet cast cement-based material providing the outer material of the block is held during a curing process.
  • Such a mould can be aligned so that it is in one sense vertical so that facing sides are formed while being held in a vertical alignment.
  • a block in another arrangement, can be formed by having one side face lower most and then the mould is first coated with a wet cement and then either as a preformed core or otherwise, a material of lighter density is located so as to be within a core area of the block to be formed and then a final coating of wet cast cement-based material over a back of the core which can then either be rough finished or fine finished either during or subsequent to a curing at least of the wet cast cement-based material.
  • a method of manufacture which is to locate a preformed core of lighter material within a mold, then introducing in a fluid form wet cast concrete so that it is to flow to fill the mold including being around the core, and then allowing the wet cast concrete in fluid form to set.
  • the method can include a first wet cast cement-based material being inserted into the mould as a layer across a bottom of the mould, then a mixture of an expanded plastic material with a binder of sand and cement is poured into the mould to be left then to set.
  • the method can include a first wet cast cement-based material being inserted into the mould as a layer across a bottom of the mould, then a mixture of an expanded plastic material with a binder of sand and cement is poured into the mould, then a further wet cast cement-based material is poured on top of the mixture, with the thus resulting materials being then left to set.
  • the mix ratios are in preference approximately as follows although these individual ratios depend on a number of further factors so that some experimentation is needed in practise both in relation to the quantities and also the source of the commodity items such as plastersizer.
  • the aim is to get a wet mixture that allows for a reasonable distribution of the lighter polystyrene beads
  • One of the advantages of the arrangement described is that by having a wet cast cement-based material with its appropriate strength and its ability to present a finished face which has been formed by close association of the casting materials with a finished surface of the mould, that subsequent treatment of the block may no longer be necessary.
  • the invention can be said to reside in a building block of cast concrete which is substantively of rectangular proportions having thereby two sides, two ends and a top and bottom where the two sides are parallel to each other and oppositely positioned one with respect to the other, the two ends are parallel to each other and oppositely positioned one with respect to the other, and the top and bottom are oppositely positioned one with respect to the other and each have a planar surface which is parallel one with respect to the other and being further characterised in that there are a plurality of equally spaced apart protrusions each being located approximately midway between respective sides of the block and extending above the planar surface of the top and a plurality of equally spaced apart receiving cavities extending into the planar surface of the bottom each cavity corresponding in spacing apart so as to receive a one protrusion extending into a bottom surface and where the respective protrusions and apertures are in respectively mutually corresponding positions.
  • wet cast concrete includes polystyrene foam particles.
  • protrusions are orthogonally symmetrical with respect to the block.
  • the cast concrete is a lightweight concrete by having a core that is of a less dense than a remainder of the block.
  • wet cast concrete is a concrete with particulate foamed plastics integrated there through.
  • the invention may also apply to a construction in which a first block as characterised anywhere hitherto is positioned on a second block as characterised anywhere hitherto and the first said block having upwardly directed protrusions engaging within corresponding cavities within an underneath face of the second said block.
  • the invention can reside in a block as above where the protrusions are of pyramidal shape.
  • the invention can be said to reside in a building block comprised of at least in the main by weight cement, and having a core of lighter material than the material of a remainder of the block.
  • the invention can be said to reside in a building block comprised of at least in the main by weight cement, and having a core of lighter material than the material of a remainder of the block, the core being a mixture of expanded plastics and a binder.
  • the invention can be said to reside in a building element including a body with three sets of opposedly positioned sides defining thereby a generally rectangular shape, the body having a core of a first material and a second different material from said first material surrounding the core material providing thereby an at least substantially continuous outer surface of said second material, and a one side of a one of the set of opposing sides having at least one protrusion extending outwardly from a planar surface of the side and at least one cavity in the further opposed side of the same set of opposed sides in a position and of a size to receive and effect an alignment of a further block having the same shape and size of this first defined block by receiving a or the protrusions into the cavity or cavities.
  • the invention can be said to reside in the above where the second material is more dense than the first material.
  • the invention can be said to reside in the above wherein the second material is made from a mix comprising cement, sand and water.
  • the invention can be said to reside in the above wherein the first material is made from a mix including cement, sand, water and polystyrene.
  • the invention can be said to reside in the above wherein the protrusion is of frusto conical shape with a wider portion closer to a main body of the element.
  • the invention can be said to reside in a the above where the block is a composite and wherein the engagement means includes at least one male portion on a first surface, and at least one female portion in a second surface opposing said first surface, wherein in use a female portion is adapted to accept a male portion for the purpose of joining and causing to be aligned two building blocks.
  • the invention can be said to reside in a building block being a body with three sets of oppositely positioned sides a planar shape or a planar base shape each planar shape or planar base shape aligned to be at right angle to each of the other shapes defining thereby a generally rectangular shape, the body having an inner core of a first material and an outer portion of a second material which is of a different density to the said first material providing thereby an at least substantially continuous outer surface of said second material surrounding the said first material.
  • the invention can be said to reside in a building block being a body with three sets of oppositely positioned sides each being of a planar shape or a planar base shape each planar shape or planar base shape aligned to be at right angle to each of the other shapes defining thereby a generally rectangular shape, the body having an inner core of a first material and an outer portion of a second material which is of a different density to the said first material providing thereby an at least substantially continuous outer surface of said second material surrounding the said first material, a one side of a one of the set of opposing sides having at least one protrusion extending outwardly from a planar surface of the side and at least one cavity in the opposite side of the same set of opposed sides in a position and of a size to receive and effect an alignment of a further block having the same shape and size of protrusion and cavity as this first defined block and adapted thereby to receive a or the protrusions into the cavity or cavities.
  • protrusions are positioned so that they are spaced apart central axis to central axis along a longer length of the block by a distance which is the same as the width face to face substantially of the block.
  • each protrusion at an end of a block is a distance away from the end face of the block by a distance which to an axis of the protrusion is one half the distance of the width face to face substantially of the block.
  • each block can be positioned with an interlocking engagement at right angles to the elongate direction of an underlying block.
  • the invention can be said to reside in an assembly of two blocks each of which is characterised as elsewhere herein and where the dimensions and shape of a first of the blocks are substantially identical to the dimensions and shape of a second of the blocks where the first of the blocks is positioned above and aligned to have a front and rear face of each define for each a common plane and where the first block with its bottom face is resting on, directly aligned and adhering by a thin adhesive interface extending at least substantially between the two mating faces.
  • FIG. 1 is a perspective view from above and one side of a block according to a first embodiment
  • FIG. 2 is a perspective view of the same block as in FIG. 1 viewed from a side,
  • FIG. 3 is a perspective view of the same block as in FIGS. 1 and 2 being the first embodiment where there is a part cutaway to show an outer facing coat and an inner core, and it also shows the arrangement of projections from a top face and cavities into a lower face,
  • FIG. 4 is a cross-sectional view of two blocks placed one upon the other in an interlocking relationship and joined in this case by an adhesive between inter-engaging faces, the two blocks being shown being the same as the block shown in the preceding FIGS. 1-3 ,
  • FIG. 5 is a plan view of the first embodiment as shown in the previous figures.
  • FIG. 6 is a side elevation of the same block as in the previous figures with a part cutaway across a bottom portion
  • FIG. 7 is a side elevation of the same block as in the preceding drawings and according to the first embodiment and a left hand corner at the bottom being shown in part cutaway and the cavities being shown in dotted outline.
  • FIG. 8 is a side elevation of a plurality of blocks placed in an appropriate interlocking position with, however, the lower layer of blocks being located on a mortar bed which is positioned on the upper face of a supporting foundation,
  • FIG. 9 illustrates the way in which an upper block is positioned and able to be manipulated so that one corner can be located first, the block lowered pivotally about that support without necessarily damaging vulnerable edges of cavities or projections,
  • FIG. 10 shows the position resulting from the actions as shown in FIG. 9 .
  • FIG. 11 illustrates an assembly showing a first course of blocks positioned on a mortar bed foundation with a second overlapping across two blocks where a first of the blocks is at right angles forming a corner
  • FIG. 12 is a further illustration of the way in which a block can be manipulated and lowered onto a set of blocks beneath the upper block without damage to either cavity or projections,
  • FIG. 13 illustrates a mould to be used in the manufacture of blocks according to a further embodiment
  • FIG. 14 is an enlarged view of a portion of the view as in FIG. 13 , except that there is now shown a coating of cement to provide a wet cast outer surface to a block,
  • FIG. 15 shows the mould as in FIGS. 13 and 14 which have now been pivoted to bring to the two sides together and the mould has been firstly coated with wet cast cement-based material and filled with a lighter cement and there is a top to the mould also coated with wet cast cement-based material to be inserted into the top of the material in the mould,
  • FIG. 16 is an exploded view of parts including the die that where there is now a preformed core, spaces to keep the preformed core centrally positioned, and such that there can be a space between the preformed core and the mould in which wet cast concrete can be poured and appropriately vibrated as appropriate.

  • FIG. 18 is a perspective view of a further die where the block is to be cast on the flat and where a first coating of wet cast cement-based material is placed over a lowermost face and a remainder of the material is then poured over this and fills the die with a back surface being floated,
  • FIG. 19 is an exploded view of the parts providing the assembly of FIG. 18 .
  • FIG. 20 , 21 and 22 are perspective views of a further embodiment where the block is a masonry composite with uppermost protrusions and lowermost cavities being correspondingly shaped and positioned and being in each case of a shape which is semi spherical.
  • a first of these is that there is a finite time before a mortar bed will set so that the height a particular wall can be constructed to is limited when underneath beds have been not been fully cured.
  • constructional strength of a wall depends upon the weight of individual members resting on others and only to some extent the physically weak bond that might occur between a mortar bed and the brick or block that is positioned on it.
  • the block 1 has upper 2 and lower 3 surfaces which include a plurality of protrusions for extending from an otherwise generally planar surface 2 and a plurality of cavities 5 inset from the surface 3 .
  • the arrangement of the protrusions 4 in relation to the surface 2 and the arrangement of the cavities 5 in relation to surface 3 are such that the protrusions 4 will generally locate within and generally therefore interlock with the consistently aligned and placed cavities with respect to the protrusions.
  • Each protrusion is of a common shape and dimension and in this case is of frusto-conical shape with the wider base of the frusto-cone lowermost in line with the otherwise planar surface of the surface 2 and the top of the frusto-cone shown for instance at 6 is co-annular with the lower diameter 7 and such that the angular relationship of the side wall shown for instance at 8 is approximately 45° to the horizontal or vertical.
  • each adjacent frusto-cone protrusion 4 shown typically at 9 is the same distance as the width between the broader faces 11 and 12 , this width being shown at 10 .
  • each protrusion has its axis so that it is equally distant between the respective faces 11 and 12 and the axis at each end is a distance from the end which is one half of the width of the block.
  • the cavities 5 having a frusto-conical shape generally matching that of the protrusions 4 nonetheless have the dimensions in which a one of the protrusions will protrude into a one of the cavities 5 and with a clearance of only a small amount, for instance, perhaps 1 or 2 millimetres typically, one will interlock therefore and inter-engage with the other to maintain a block above having these same characteristics with a block below.
  • the cavities 5 mirror the relationships as described in relation to the protrusions 4 . To this extent then they have each a central axis passing vertically through each of these and each of these axes is separated from an adjacent axis by the width 10 of the block.
  • the end cavity for instance at 14 , has its axis at, within the tolerances acceptable within the building industry, one half the width 10 of the block away from the end 15 .
  • each cavity there is a sidewall 16 which is at 45° to its central axis and a top of the respective cavity is a circular area half the diameter of the lower circular area coincident with the surface 3 .
  • the block in general is of rectangular shape in this case and has each of the respective oppositely positioned surfaces at parallel alignments and at right angles one with respect to the other.
  • respective alignments of interlocking blocks will depend upon accuracy of the interconnecting faces so that instead of a mortar bed which will have a thickness of perhaps one or two centimetres, it is expected that this will now provide for, if desired, a connection to be made using an adhesive or glue where the separation between the respective mating faces is very small indeed and might be typically one or two millimetres.
  • each block can be placed into position very quickly and of course, many blocks can be placed one upon the other quite quickly because the time required to allow for a sufficient adhesion between facing surfaces is not so critical because additional weight on top of one another will not of itself significantly harm the adhesion between the surfaces even when the adhesion is still uncured.
  • the block 1 includes a core 20 which in this case is made from styrene foam mixed with wet castable cement.
  • cement is used throughout to describe a material that is or has similar properties to portland cement but can include where the context permits to also include the case where the “raw cement” includes a sand or like extender.
  • While a block 1 has been shown with a line of six protrusions and six matching cavities, various other modular sizes can also be made and also there can be some blocks which are appropriate to include so that one side extends along one side of a wall, and another part extends along another side of a wall in which the two respective walls are at right angles, one to the other.
  • a main block the general dimensions of which are as follows, namely width, height, length, height of each protrusion from base to peak, angle of side of each protrusion, difference in diameter between the cavity and protrusion in each case, all up weight of the block, where this is fully encased with an outer wet cast cement-based material.
  • FIG. 4 shows in a typical cross-sectional view how two blocks will be expected to sit one on the other and each having an expanded polystyrene foam core and an all round wet cast facing.
  • FIG. 8 shows specifically the way in which the blocks may in the first instance be located on a foundation which doesn't have appropriately positioned protrusions.
  • the blocks can be located on a mortar bed and will require some skill in order to set these up accurately and aligned.
  • the difficulty that is being considered here is that if one has a relatively heavy block that is to be located one upon the other, then if for instance the cavity and the protrusion each had parallel sides with very little tolerance, it would be appropriate to then position the top block fairly accurately above the lower one and then lower these once relatively accurate alignment had been established.
  • FIG. 11 is a further illustration of the way in which a first course can be positioned on a foundation where in this case the mortar base fills the cavities.
  • FIG. 13 there is a die 40 which is made from two parts, 41 and 42 , which are joined together by a central hinge so that they can be hinged together into a shape that is shown at 15 .
  • a release agent is spread over the mould.
  • the thin layer 43 of the wet cast cement-based material is coated throughout the die and in this case also is extended although not specifically shown as such into the shapes at 44 .
  • the two halves 40 ad 41 are brought together and a mixture of polystyrene foam and Portland cement and sand together with plastersizers and accelerants as previously described are mixed together and once mixed are poured as shown in FIG. 15 .
  • a cap 45 which is also coated with wet cast cement-based material and 46 is placed into the top of the mould at 47 and then the whole of this is then left to let the wet cast cement-based material generally cure.
  • the polystyrene foam may have a tendency to separate from the wet cast cement-based material if the whole is subjected to vibration for instance.
  • vibration is conventional in such applications in order to consolidate the wet cast cement based material and to remove pockets of air.
  • the preformed core 50 is positioned and kept separate from the outer walls by appropriate spacers such as at 51 , 52 , 53 and 54 and then otherwise, the mould as described in the earlier FIGS. 13 , 14 and 15 is used.
  • FIG. 17 this illustrates the batch method of moulding a core and then cutting material from this.
  • a further embodiment however, includes a mould 60 as shown in FIGS. 18 and 19 which is intended to be adjustably held in position with a clamp 61 which includes clamping hold-down bolts 62 and a hold-down frame 63 .
  • the sides of the surround defining the mould which is now an open top mould includes opposite sides 64 and 65 with appropriate shapes to define the cavities, for instance at 66 and protrusions at 67 .
  • the first coat on the floor 68 is a coating of thickness perhaps of between 1 and 2 centimetres depth fully across the floor and thereafter simply the wet precured mixture of wet cast cement-based material and polystyrene.
  • the polystyrene material in this case will define the outer thinner edges of the block thus formed and the back of the block in this case will not be defined by a mould as such but can be floated in conventional manner or it can have a rough finish which can if needed be ground to a smoother facing finish afterwards.
  • FIGS. 20 , 21 and 22 show perspective views of a further embodiment where the block is a masonry composite with uppermost protrusions and lowermost cavities being correspondingly shaped and positioned and being in each case of a shape which is semi spherical.
  • the block 70 is of rectangular proportions with a chamfer edge 71 along an upper edge of a side 72 .
  • the protrusions 73 are each of semi spherical shape and are located at spaced apart locations which are equidistant from each plane defined by a side 72 and side 74 . Further the spacing is also arranged that when a like block is positioned end to end with the said first block then the protrusion 75 at a first end of the first block will be approximately the spacing distance from a protrusion at an adjacent end of the second block. This allows for overlapping with an interlocking alignment to be achieved.
  • the cavities 76 are each of a corresponding in size and semi spherical shape to the protrusions extending from the oppositely positioned top of the block 70 , extending through the otherwise planar bottom of the block 70 and are correspondingly positioned so that each is spaced to be equidistant from a planar alignment defined by the respective sides 72 and 74 and are also each an equal distance apart one from the other except that they are approximately one half this distance from a plane defined by an end of the block 70 .
  • the block as previously described is a composite masonry block where there is an outer facing 77 of a higher density material to provide a harder and tougher facing with an inner core material 78 of lesser density. This allows for a larger block for given overall sizes where there may be a weight restraint established by occupational lifting restrictions.
  • the inner core material is an extended material provided by a mixture of expanded plastics material particles, and a binder in this case a cement chosen in this case to be portland cement, and sand. It is a difficulty that using a light material such as expanded polystyrene is made easier if a superplastisizer is also used which assists in mixing.
  • the block shown in this further embodiment is able to be manufactured as in any of the earlier described methods and will enable blocks of similar shape, size and configuration to be joined by an adhesive so that they can be closely conforming in position and by having the tougher outer face have a better face
  • protrusions and cavities While a description has been given of protrusions and cavities, and these have been shown with a circular cross-section in plan, there could be in a broader sense some variations from such circularity and even a square shape would be possible although less preferred provided that a cavity would fit over such a protrusion equally well from one alignment of an elongate direction of the block to an alignment at right angles of an elongate direction of a further block to this.
