Definitions

  • the invention relates to a device or devices which support centrally or any other positional requirement, reinforcement or any other structure which is built in to the mortar bed joint in any masonry construction, and support the masonry units until a time where the mortar has become load bearing and/or stable.
  • the invention provides reinforcement elements such as support feet.
  • the support feet can be of any shape and size in relation to the particular construction requirements but are typically 10.7mm in height and 23mm in length with a mid section width of 8mm (see Fig. 1).
  • the height of the support feet can vary to accommodate masonry tolerances which will also then allow the user to build to gauge e.g. 10.7mm and 9.0mm or whichever sizes are deemed necessary to achieve gauge height.
  • the support feet can be made with a wide variety of materials such as plastic, ceramics, metal, etc.
  • the support feet can be manufactured using different methods of manufacture relating to the selected material to be used.
  • the support feet can be clipped on to the reinforcement or moulded on to the reinforcement or structure, suspending the reinforcement or structure at the optimum requirement in the mortar bed.
  • the reinforcement/structure can then be laid onto the masonry or into the mortar and the mortar applied with the masonry units laid onto the mortar with enough pressure to compress the mortar until they come to rest on the supports, the excess mortar then can be removed as normal.
  • the support feet can be clipped on or otherwise located by whatever means to secure them or maintain their position in relation to the reinforcement/structure.
  • the support feet could be over moulded onto the reinforcement/structure or by any other relative manufacturing techniques.
  • the support feet can be used with a wide range of reinforcement/structure sizes and shapes and is not limited in any way if the reinforcement/structure are bridging cavities or any other voids.
  • the support feet can be manufactured to suit any angle of support when attached to the reinforcement/structure typically 45 degrees.
  • Fig. 1 shows a support according to a first embodiment of the invention
  • Fig. 2 shows a support according to a second embodiment of the invention
  • Fig. 3 shows a support according to a third embodiment of the invention
  • Fig. 4 shows a support according to a fourth embodiment of the invention
  • Fig. 5 shows a support according to a fifth embodiment of the invention
  • Fig. 6a shows a support according to a sixth embodiment of the invention
  • Fig. 6b is an alternative view of the support of Fig. 6a;
  • Fig. 7a shows a support according to seventh embodiment of the invention
  • Fig. 7b shows an alternative view of the embodiment of Fig. 7a
  • Fig. 7c shows an alternative view of the embodiment of Fig. 7a
  • Fig 8 shows a support according to an eighth embodiment of the invention.
  • Fig. 9 shows a support according to a ninth embodiment of the invention.
  • Fig. 1 shows a triangular type support (1.1) supporting the reinforcement centrally at 45 degrees with the V notch clip on type (1.2), with an extended collar (1.3) for additional stability; and
  • Fig. 2 shows a spherical type, support (2.1) again supporting the reinforcement centrally, with a V notch (2.2) clip on function.
  • FIG. 3 A further embodiment is shown in Fig. 3 in which the support feet or reinforcement element have a generally diamond cross-section tapering from a central width to point or chamfered upper and lower spacing ends together with a cut-out, groove or notch into which the reinforcement structure fits.
  • Fig. 4 is yet another embodiment in which the reinforcement element includes a central core and a plurality of limbs extending therefrom symmetrically. For example four limbs can project symmetrically from the central core such that the reinforcement element is stable whichever three limbs contact a supporting surface. The three supporting limbs straddle the reinforcement structure to locate the reinforcement element and the fourth projects upwardly so as to provide the spacing function required.
  • FIG. 5 A further embodiment is shown in Fig. 5 in which the support feet or reinforcement element (5.1) is generally X shaped when viewed from above.
  • Each of the four limbs of the reinforcement element (5.1) has a generally diamond cross-section tapering from a central width to a point or chamfered upper and lower spacing ends.
  • the centre of the X shaped element has a cut out (5.2), groove or notch into which the reinforcement structure fits.
  • Figs 6A and 6B show yet a further embodiment in which reinforcement elements 600 comprise support feet 602 joined by a crossbar 604.
  • Each support foot is of appropriate configuration for snap fitting or otherwise fitting over or onto reinforcement steel rods or wires 608 and hence include an aperture 606.
  • the feet 602 can be of any appropriate configuration for example that described in any of the embodiments described herein.
  • the feet 602 may have a diamond cross-section tapering to points top and bottom defining spacing ends.
  • the feet 602 may be mounted at any appropriate orientation to the crossbar 604 for example at a 45 degree angle providing additional stability in use.
  • the feet are snapped on or moulded onto or otherwise fitted onto reinforcement 604 by push-fitting the orifice 606 over the rods 608.
  • the crossbar then holds the reinforcement rods 608 in an appropriate spaced configuration to act as a masonry support and gauge reinforcement system. As a result no additional crossbars are required between the reinforcement rods 608.
  • the reinforcement elements 600 can be formed in any appropriate manner for example by moulding, wherein the feet 602 and crossbar 604 are integrally formed of any appropriate plastics material.
  • a reinforcement element designated generally 700 and including feet 702 and a crossbar 704 is fitted to reinforcement rods 708 by snapping an orifice 710 over the rods or feeding the rods 708 through the orifice as appropriate.
  • Each of the feet 702 is generally of a Y-shape viewed in plan with a central limb 712 transitioning into the crossbar 714 through which the orifice 710 passes and two forked limbs 714 each extending substantially at 135 degrees to the central limb 712 and at 90 degrees to one another.
  • each of the limbs is generally diamond shaped tapering to support points top and bottom.
  • the reinforcement element can be once again formed in any appropriate manner for example by moulding as a single integral part.
  • first and second angled limbs 714 relative to the crossbar 704 provides additional stability and resistance to tilting or rotating of the reinforcement element 700.
  • the reinforcement rods in the embodiments described above may be of any appropriate diameter for example 3 to 5 millimetres and that the apertures or orifices in the reinforcement elements can be sized appropriately.
  • the apertures can be resilient to allow gripping of a range of sizes or a diaphragm can be provided as shown in Fig. 8.
  • a reinforcement element shown generally at 800 but which may be of any appropriate configuration includes an orifice 802 through which a reinforcement rod (not shown) may be inserted or into which it can be slipped via an appropriate notch (not shown).
  • the orifice 802 includes a central diaphragm 804 comprising an annular ring of thin plastics material defining a central aperture 806 of smaller diameter than that afforded by orifice 802. Accordingly when a smaller diameter reinforcement rod is inserted it will sit in the orifice 806 formed by the diaphragm 804. When a larger diameter rod is inserted it will simply break through the orifice 804 and be held in place in the larger orifice 802. A plurality of diaphragms defining progressively smaller orifices may be provided.
  • Y-shaped feet 702 shown in Fig. 7 can be used as individual reinforcement elements without crossbar 704 in the manner described with reference to, for example, Hg. 3.
  • a masonry reinforcement element designated generally 900 includes a generally elongate body 902 having a first portion 904 and a second portion 906 hinged together for example by a thinned region such as a living hinge 908.
  • the first portion further includes a detent aperture 910 arranged to receive a detent or catch 912 extending from the second portion 906 when it is folded about the living hinge to mate with the first portion 914.
  • the catch 912 can comprise, for example, a pair of outwardly biased barbed fingers with inclined upper faces such that upon insertion into the aperture 910 the fingers are pushed together allowing the first and second portions 906, 904 to be closed relative to one another, the fingers 912 springing apart once they escape the aperture 910 to lock the two parts together.
  • the first portion 904 may further include a cut-out portion 914 on an opposing face to the aperture 910 into which a user's fingers or an appropriate tool can be inserted to release the fingers 912 by pushing them together allowing the second portion to be hinged away from the first portion.
  • the elongate portion has a generally diamond cross-section of the nature described in more detail above.
  • the first and second portions may each have a half-diamond cross-section such that when folded together the diamond cross-section is formed.
  • the first portion may have an additional protruding half diamond section 916 on the face which receives the second portion acting as an extension of the half-diamond section of the second portion when it is locked in position.
  • the first body portion has first and second limbs 918 projecting at respective symmetric angles from an end in the range 100° to 140° to the body portion in the vicinity of the living hinge 908. The limbs also have a diamond cross-section of the type discussed above.
  • the support as a whole forms a generally Y shape.
  • the first and second portions further include reinforcement rod receiving formations 920, 922.
  • the receiving formations comprise a generally U-shaped cut out in the upper face of each portion (i.e. the faces which mate in the hinged closed configuration) and positioned such that the formations mate in the hinged closed position defining a passage generally perpendicular to the elongate dimension of the support.
  • each of the formations includes a thin obstructing membrane 926 across its centre and forming a continuation of the body portion across the formation.
  • the rod is laid across the thinned membrane 924 (or 926) in the formation 920 (or 922), while the support 900 is in its opened position.
  • the membrane is of sufficient frangibility that it is deformed or otherwise displaced such that the rod is gripped firmly between the membranes forming an aperture between them.
  • the materials can be selected appropriately for example any appropriate plastics material.
  • the membranes 924, 926 may be for example of 0.5 millimetres thickness and the dimensions of the remaining parts can be of any appropriate size for example as discussed above in relation to other embodiments.
  • the reinforcement rod can be machined in order to reduce the risk of axial slippage when embedded in mortar.
  • the rod can have indentations stamped in at regular intervals providing a flattened region in the generally circular cross section.
  • the diameter of the rod may range from three to five millimetres and the indentation may range from one quarter to one millimetres on respective opposing sides. In a preferred approach a four millimetre diameter rod may be indented between
  • the indentations can be at any desired spacing for example every 400 or 500 millimetres along the rod.
