Definitions

  • This invention relates to a building block system.
  • a relatively common proposal is of substantially T-shaped blocks, i.e. a block consisting solely of a stem limb and a cross limb, the stem limb extending substantially perpendicularly from the middle of the cross limb, examples being disclosed in British Patent Specification 590,291, French Patent Specifications 1067762 and 2299468 and United States Reissue Patent Specification 14,904.
  • the block is laid such that the cross limb extends in the general plane of the wall, whilst the stem limb extends perpendicularly to that plane.
  • Swedish Patent Specification 150829 discloses a building block which, although it appears to be substantially T-shaped when seen in front elevation and rear elevation, actually consists of six limbs, of which four provide the front and rear T-shapes and of which each of the other two links one end of the cross-limb of the front T-shape with the nearer end of the cross-limb of the rear T-shape.
  • This building block is of its special shape because it is used to form ventilation or like channels in the wall.
  • substantially T-shaped blocks when interfitted with the free end of each stem limb face-to-face with the cross limbs of two adjacent blocks, utilize the interfitting to support each other at two opposite sides of the six sides of the block, they provide no similar support at any of the other four sides.
  • United States Patent Specification 829,480 discloses a paving and building block system wherein each block consists. of two block-form parts whereof a larger part protrudes from the smaller part on four sides. These blocks can interfit such that the larger parts of four outer blocks overlap the larger part of an inner block at its respective four sides. Although forces applied to the major external face of the larger part of the inner block are borne by the larger parts of the four outer blocks, forces applied to the major external face of the smaller part of the inner block are not borne by any adjacent blocks.
  • each block has the end faces of its cross limb diverging towards its stem limb, and has the lateral faces of its stem limb substantially parallel to the respective nearer end faces of its cross limb and thus diverging away from the cross limb, and, moreover, those two intermediate faces of the cross limb between these respective end faces, on the one hand, and these respective lateral faces, on the other hand, converge towards the longitudinal axis of the cross limb progressing inwardly.
  • a keying arrangement of substantially Z-form which, in a wall constructed from the blocks, resists forces on those faces of any one of the blocks at the major faces of the wall.
  • French Patent Specification 1352121 discloses a building system employing three shapes of interfittable elements, these shapes being substantially Z, substantially T and substantially L.
  • forces against the free end face of the stem limb of such T-shaped element or against the free end face of the longer limb of such L-shaped element are not borne by the adjacent elements except by way of conventional fastening means, for example rivetting, used to fix the elements together.
  • This invention seeks to provide a building system in which blocks are employed that are of compound shape, that is to say, are not basically rectangular parallelepipeds.
  • the block employed in a system in accordance with the invention may be substantially T-shaped, substantially Z-shaped and/or may be dove-tailed and may co-operate with other compound-shaped blocks to produce buildings or other structures in which the various blocks strengtheningly support one another with, or without, interlocking co-operation, it being possible for the buildings or other structures to be completed, in some cases, without mortar or other binding material between the blocks or, in other cases, to employ a relatively small amount of mortar or other binding material between the blocks as compared with buildings and other structures produced from conventional blocks, particularly bricks.
  • the present system advantageously employs blocks which are pre-fabricated to a high degree of precision and with which the required fitting together, especially interlocking, of the blocks will not be achieved, during the erection of a building or other structure, unless the individual blocks are correctly disposed relative to one another and register accurately.
  • the system advantageously includes the use of complementary blocks such as end blocks, corner blocks, junction blocks and so on.
  • a wall comprising a plurality of unitary building blocks each consisting of only two limbs which are a stem limb and a cross limb, the stem limb extending substantially perpendicularly from the middle of the cross limb, and the longitudinal axis of the cross limb extending in the general plane of the wall characterised in that the longitudinal axis of the stem limb also lies in said general plane.
  • T-blocks in this manner in a wall, which may be a vertical wall, or a horizontal wall, for example a floor or a roof, gives a greater degree of flexibility in building construction, in particular with walls intended to bear no load or low loads, since these walls can be of lesser thickness than when the stem limbs of the blocks are perpendicular to the general plane.
  • a unitary building block comprising only two block-form parts whereof one part protrudes from the other part at first and second adjacent sides of said block to provide first and second keys thereat, characterised in that said other part protrudes from said one part at third and fourth adjacent sides of said block to provide third and fourth keys thereat.
  • This building block has the advantage that, when interfitted with identical building blocks in a wall, the blocks support each other not only against forces applied to two opposite sides of the block but also against forces applied to another two sides of the block.
  • a range of building elements of various shapes characterized in that the elements of various shapes are provided with substantially Z-form keys which are of substantially identical linear and angular dimensions to each other and each of which has its intermediate limb at an acute angle to its other two limbs.
  • a substantially vertical wall comprising a plurality of unitary building blocks each formed at first and second opposite sides thereof with substantially Z-form keys, the keys of said blocks being substantially identical to each other and interfitting and each block having at third and fourth opposite sides thereof alternating with said first and second opposite sides thereof respective substantially parallel faces, characterised in that said faces and the substantially Z-forms of the keys of the blocks extend in substantially horizontal planes.
  • a vertical wall constructed in this manner with blocks provided with Z-keys has the advantage that a lowermost course of the blocks can be laid directly on a horizontal foundation surface without requiring interposition of differently shaped blocks.
  • a building block including at first and second opposite sides thereof respective first and second substantially Z-form keys whereof the substantially Z-forms extend substantially parallelly to each other, characrerized in that the first and second keys are situated directly opposite each other along said sides.
  • This block has the advantage that a plurality of them can be laid with their keys interfitting without requiring inversion of alternate blocks and without alternate blocks protruding significantly.
  • a wall comprising a plurality of unitary building blocks each consisting of only two limbs which are a stem limb and a cross limb, the stem limb extending substantially perpendicularly from the middle of the cross limb, and the longitudinal axis of the cross limb extending in the general plane of the wall, characterized in that the longitudinal axes of the stem limbs of some of the blocks extend in said general plane and the longitudinal axes of the stem limbs of others of the blocks extend perpendicularly to said stem limbs of some of the blocks.
  • This arrangement of substantially T-shaped blocks is particularly useful in providing a relatively strong wall.
  • Figures 1 to 15 of the drawings show the use of building blocks 1 that are substantially T-shaped.
  • Figures 1 and 2 of the drawings show two upright walls 2 and 3 of a building or other structure formed from such T-shaped blocks. It will be seen that, in each horizontal course of blocks, neighbouring blocks are alternately upright and inverted and that, in the structure of Figure 1, each block is inverted relative to blocks which are vertically thereabove and/or there- beneath whereas, in the structure shown in Figure 2, each block in each course has the same disposition as does each block which is vertically thereabove and/or therebeneath.
  • the T-shaped blocks co-operate to form a 90° junction between the two upright walls without the need to employ blocks of any other shape. It will immediately be apparent that, measured in the general plane of its wall, the horizontal or cross limb 4 of each block is three units long, the vertical or stem limb 5 thereof is one unit long, and each limb 4 and 5 is one unit wide.
  • the basic T-shaped block of Figures 1 and 2 is preferably given tapered projections 6 to 8 and depressions 9 to 11 as shown in Figures 3 and 4 for a hollow block 12 and each one unit square in effective area, or projections 6' to 11' and depressions 6" to 11" each with an effective area of one unit by one-half unit, as shown in Figures 5.
  • These projections and depressions provide significant keys between the blocks 12, enabling them to be fitted satisfactorily together without the use of mortar or other binding material when a wholly or principally dry construction is required.
  • the projections and depressions co-operate with each other to form satisfactory seals at the joints between the blocks which is a considerable advantage if the hollow blocks are to be filled with an initially foamed or liquid insulation material or with foamed or other concrete.
  • Figures 6, 7 and 8 of the drawings illustrate the form and use of blocks which may conveniently be described as Z-key, T-blocks.
  • the end faces of the cross limb 14 of the substantially T-shaped block 15 and the lateral faces of the stem limb 16 thereof are of a shape to give substantially Z-form keys 17 which are identical to each other, especially in their linear and angular cross-sectional dimensions, with the intermediate limb 18 of each key being at an acute angle to its other two limbs 19.
  • Figures 7 shows a corner substantially T-shaped block 20 which differs from the block 15 chiefly in that the key 17' of one branch of the cross limb 14 is arranged at a rear face of that cross limb.
  • Figures 8 show two blocks 20 interfitted correspondingly to the blocks A and B in Figure 1.
  • the substantially T-shaped blocks of Figures 6 to 8 are, in any construction employing them, keyed to their neighbours on two sides and this produces equilibrium among the forces acting on each block, it being noted that Z-keyed blocks are usable in slab form as floors and also in slab form as roofs which latter can be employed either with, or without, additional supports.
  • the vertical walls 30, 31 and 32 extending perpendicularly to each other consist of substantially T-shaped identical blocks 33 with cross limbs 34 three units long and one unit wide and stem limbs 35 one unit square, substantially L-shaped identical blocks 36 with stem limbs 37 two units long and one unit wide and cross limbs 38 one unit square, and identical square-section blocks 39 one unit square.
  • Figures 10 shows one of the blocks 33 with the end faces of its cross limb 34 and the lateral faces of its stem limb 35 consisting of substantially Z-form identical keys 17 which differ from the keys 17 of Figures 6 only in that their faces are perpendicular to the plane of the block.
  • Figure 11 shows a block 33 differing from that of Figures 10 only in that it has substantially Z-form keys 40 whereof the limbs of the substantially Z-shape are at right angles to each other.
  • the block 33 of Figure 12 is usable in walls according to both Figures 1 and 9 and has its keys 41 of substantially V-shape with the limbs of the substantially V-shape lying in a plane perpendicular to the axis of the stem limb 35.
  • the block 33 of Figure 13 differs from that of Figure 12 only in that its keys 42 are of a cylindrical concave or cylindrical convex form.
  • Figure 14 shows the walls 30 to 32 constructed of substantially T-shaped blocks 50, substantially L-shaped blocks 51 and substantially square-section blocks 52 differing from the blocks of Figure 9 chiefly in that the substantially T-shaped blocks each have one or both of those two faces 53 thereof intermediate the end faces of its cross limb, on the one hand, and the lateral faces of its stem limb, on the other hand, converging towards that face 54 of the cross limb opposite the stem limb.
  • each substantially T-shaped block 50' is of elongate formation.
  • Each of the four versions of the embodiment of the system which principally employs substantially T-shaped blocks may be solid, or wholly or partly hollow, and may have plain and/or patterned or other textured faces. It will be apparent that many different combinations of precise shape, size, materials, surface texturing and so on are possible that are too numerous to discuss individually. The particular type which is chosen will depend upon individual preference, climatic conditions, geographic situation and local traditions of building.
  • prefabricated concrete will generally be employed and most blocks will be hollow in construction, other materials can equally well be used, if preferred, such as pre-stressed concrete to form blocks usable for vertical walls, floors, roofs and so on, but a construction employing concrete is not essential and the blocks can be made from, for example, glass-reinforced plastics, natural wood and/or plywood.
  • the use of the building system which has so far been described enables strong buildings or other structures to be made either in dry form or semi-dry form using very much less mortar or other binding material than is employed in the formation of traditional brick/block buildings and the like.
  • the described system has considerable advantages as compared with traditional building systems and these advantages include stability both during and after erection of a building or other structure, ease of erection, simplicity in aligning the blocks without long experience of such work being necessary, and the use of an absolute minimum of auxiliary tools, measuring instruments and other gadgets.
  • the blocks can be such as to interkey, giving increased strength to the vertical wall, floor, roof or the like which is being produced whilst simultaneously eliminating errors such as discrepancies in level and the formation of crooked, zig-zag, curved or other incorrectly disposed courses of blocks.
  • the system is versatile since it can employ different forms of keying and can employ any chosen one, or any chosen suitable combination, of the different blocks that have already been described and those that will be described below.
  • the system can be used for many other purposes such as, for example, the paving of roads, pathways, pavements and the like and for the cladding of new or existing buildings.
  • the blocks will usually be formed from conventional concrete, they can, as has already been mentioned above, be formed from other materials which include, in addition to the examples already mentioned, light-weight concrete, clay, gypsum and synthetic plastics whether or not reinforced with glass fibre or the like.
  • buildings or other structures can be produced without mortar or other binding material between the blocks but grouted cavities can be included, where required, for strength and/or insulation.
  • a building or other structure can be formed in such a way as to be capable of being readily dismantlable by including therein removable keying blocks and/or removable locking bolts.
  • the blocks may be given surface textures designed to simulate the use of a traditional method of construction when viewing the exposed surfaces of a building or other structure formed from such blocks.
  • this system can be employed in producing either permanent or temporary shuttering, substantially T-shaped blocks which are formed from glass fibre reinforced plastics or wood being particularly suitable for shuttering purposes. If exceptional strength is required in the blocks, they may be formed from glass fibre reinforced concrete but the particular choice of material will naturally depend upon the nature of the building or other structure that is to be formed and the purpose for which it is required.
  • the hollow interiors of the blocks can, for extra strength, be filled with concrete or cement grout and it is possible to insert reinforcing bars into those interiors, before pouring the concrete or grouting, and it has already been mentioned that the hollow blocks can be filled with insulation material, such as urea-formaldehyde foam, by either pouring or injection.
  • insulation material such as urea-formaldehyde foam
  • the system is particularly convenient for forming temporary buildings or other structures since the blocks and other necessary items can be supplied in a partially assembled condition with post units bolted to beam units merely requiring the interlocking blocks to be correctly positioned. Under such circumstances it is, of course, necessary that provision should be made for disassembling the temporary building or other structure in one of the ways briefly discussed above.
  • the blocks that have been described can be provided in any required sizes although it is desirable that the size and weight should not exceed that which can readily be handled by a single workman.
  • the blocks that have briefly been described with reference to Figure 15 can, on the other hand, be of such a size that mechanical assistance is required to move them, it being possible to provide blocks other than those shown in Figure 15 to form a range of modular units that are basically of T-shaped cross-section together with accessory units as may be required at wall ends, wall junctions, the margins of access openings and the like.
  • the second and third versions of the substantially T-shaped blocks may, if required, be of brick-sized dimensions and may be made from baked clay and other materials from which conventional bricks are formed.
  • the thicknesses of the substantially T-shaped blocks employed can be varied, and in particular reduced, to allow different external patterns to be produced together with different relative dispositions of the blocks.
  • This third version can, if desired, be combined with the second version, using the two versions alternately in successive tiers of the blocks.
  • a second basic embodiment of this building system employs blocks that are not T-shaped but that co-operate with one another by way of keys that are still substantially Z -shaped.
  • Such blocks are particularly, but not exclusively, useful in forming prefabricated panels, partitions and the like, a minimum of mortar or other binding material being required at the junctions between the blocks.
  • the substantially Z-shape of the key can be varied but it has been found convenient to employ four basic forms of the key any of which will join the blocks quickly and effectively together without essentially employing any mortar or other binding material.
  • Figure 16 shows a substantially Z-shaped block 70 consisting of two block-form parts 71 of which one part protrudes beyond the other on two of the six sides thereof and of which the other part protrudes beyond the one part on another two of the six sides.
  • substantially four Z-shaped keys 72 to 75 are formed at the four sides, the substantially Z-shapes of the two opposite keys 72 and 74 being parallel and identical and of an acute-angled form, whilst the substantially Z-shapes of the two opposite keys 73 and 75 are of a right-angled form although parallel and identical to each other.
  • each block 70 is four units high, each part 71 being two units high; the top and bottom faces of the block are each four units square; the intermediate limbs of the substantially Z-shape of the keys 72 and 74 are each two units long; the mid-point of the substantially Z-shape of each of the keys 72 and 74 is in a straight line with the free ends of that shape; and the intermediate limb of the substantially Z -shape of each of the keys 73 and 75 is one-third unit long.
  • Figures 17 show three different forms of acute-angled, substantially Z-shaped key.
  • the key of Figure 17A is that of Figs. 6, 7, 8, 10 and 16.
  • Figure 17B shows a key whereof the intermediate limb 80 is one unit long and the other two limbs 81 each extend, as measured in a direction parallel to the limb 80, for one unit.
  • the key is similar in proportions to the key of Figure 17A, but extends over only two units of the four-unit height of the block.
  • Figure 18 shows two courses of the blocks 70, illustrating that not only do the blocks interkey in each course by means of the keys 72 and 74 but the blocks interkey between courses by means of the keys 73 and 75.
  • Figure 19 shows that the keys 73 and 75 may also be of an acute-angled, substantially Z-shape.
  • Figure 20 illustrates a substantially Z-shaped block 90 with acute-angled substantially Z-shaped, parallel, identical keys 91 and 92, the intermediate limb 93 of each substantially Z-shape extending obliquely inwards.
  • Figure 21 is a plan view showing vertical walls 100 to 102 of a building that are formed by employing hollow blocks exhibiting the key of Figure 17A, but Figure 21 also shows the shapes of blocks that are required at a right-angled junction between two walls, two forms of T- junction between walls, and a cruciform junction between four walls,
  • Figure 22A illustrates hollow, substantially Z-form keyed, substantially Z-shaped blocks 110 which are used as permanent formwork for the construction of beams together with details of one way of fitting those blocks 110 together.
  • Figure 22B shows the shape of auxiliary hollow blocks 120, 120' that may be used surroundingly to support upright reinforcing rods or the like that are interconnected by strengthening wires.
  • substantially Z-shaped blocks that have been described herein can be employed in much the same situations as the substantially T-shaped blocks discussed above and, to a large extent, have the same advantages, as compared with the blocks that are employed in conventional building systems, as do those above-discussed blocks.
  • blocks 130 are of dove-tailed substantially T-shape and will hereinafter be called, for the sake of brevity, "dove" blocks.
  • Such blocks are again particularly, but by no means exclusively, useful in constructing pre-fabricated panels, partitions and the like, very little, if any, mortar or other binding material being required at the junctions between the blocks.
  • the dove blocks again employ substantially Z-form keys for interengagement and, once again, these keys may be of various shapes but conveniently are provided in four different versions as has already been described above with reference to Figures 17 to 20.
  • the dove blocks can advantageously be used in buildings or other structures of semi-dry form, each tier of dove blocks being overlaid with mortar or other binding material to secure it to the superposed tier in a substantially conventional manner.
  • each tier of dove blocks being overlaid with mortar or other binding material to secure it to the superposed tier in a substantially conventional manner.
  • the dove blocks it is preferable for the dove blocks to incorporate end keys of one of the same forms, and for the same purposes, as have already been mentioned with reference to Figures 16 to 19.
  • Each dove block is actually shaped to comprise two substantially Z-shaped keys 131 each extending over the whole of one side of the block.
  • This form of block has the particular advantage that, in use, the forces acting on the opposite ends thereof will almost always substantially counterbalance one another so that a particularly structurally stable building will result.
  • the dove blocks 130 have substantially the same versatility of usage, and advantages as compared with the bricks or blocks that are employed in conventional building systems, that have already been discussed above in regard to the version of the system which principally employs substantially T-shaped blocks.
  • Figure 24 is a plan view, somewhat similar to Figure 21, showing a plurality of the hollow dove blocks 130 employed in vertical walls 100 to 102 which also include matchingly shaped cruciform connecting blocks 132, "half" wall end blocks 133, T-junction blocks 134 and right-angled corner blocks 135.
  • Figure 25 illustrates one form of floor that may be constructed of substantially T-shaped blocks arranged with their stem limbs horizontal in a pre-cast concrete or steel beam or timber joist framework 140 that is of matching cross-sectional shape and that provides beams or joists at pre-determined substantially regular intervals.
  • the substantially T-shaped blocks exhibit substantially Z-form keys of the kind shown in Figure 20 and that similarly keyed dove blocks are also employed to fill the gaps which would be left if the substantially T-shaped blocks alone were used.
  • a tie beam may often advantageously be employed to maintain the blocks firmly pressed against one another as just described, such tie beam being either pre-cast or cast in situ.
  • the use of a tie beam for this purpose is particularly advantageous when the blocks are in the form of roof slabs.
