DESCRIPTION OF EMBODIMENTS

[0077] With reference to the above drawings, in which similar features are generally indicated by similar numerals, a settable material aligning arrangement according to a first aspect of the invention is generally indicated by the numeral 1000. [0078] Apparatus

[0079] In one embodiment now described, there is provided a settable material aligning arrangement 1000 for facilitating the pouring of settable material 3000 (shown in FIGS. 7 and 8) onto a support base 2000 to form a level floor when the settable material 3000 sets. While the invention is described below with reference to its application in the levelling of a concrete or cement floor, it is envisaged that the same invention can be applied for use where any settable material is applied to a support base, and that the support base need not necessarily be horizontally aligned. For example the support base can be a wall that is being shotcreted, or a wall on which plaster is being applied, whether manually or in an automated fashion. Any reference to the word “levelling” is intended to encompass the broader concept of general alignment in a required mutual plane.

[0080] The settable material aligning arrangement 1000 comprises a base arrangement 1100 configured for being mounted securely on the support base, and an aligning formation 1200 configured for defining the plane at which the floor is to be poured to.

[0081] The base arrangement 1100 and the aligning formation 1200 are coupled to each other by a coupling arrangement 1300. The coupling arrangement is configured for coupling the base arrangement 1100 to the aligning formation 1200 in preferably an infinite number of positions between an extended position in which the aligning formation is further from the support base 2000, and a retracted position in which the aligning formation is closer to the support base 2000, by means of complementary threaded formations as will be discussed in more detail below.

[0082] In the embodiments shown in the figures, the coupling arrangement 1300 comprises engaging formations associated with the base arrangement 1100 and complementary engaging formations associated with the aligning formation 1200. In the embodiments shown in the figures, the engaging formations are a spigot and socket arrangement 1310, with the socket 1330 being defined by and coupled to the base arrangement 1100, while the spigot 1320 is defined by and coupled to the aligning formation 1200. The socket 1330 is preferably tubular in shape, and the spigot 1320 is preferably also tubular in shape, and dimensioned for being received within the socket 1330. The spigot 1320 defines external threaded formations 1322, while the socket 1330 defines internal threaded formations 1332 configured for complementary engagement with the external threaded formations 1322 operationally.

[0083] It will be appreciated by those skilled in the art that the arrangement of the spigot and socket arrangement 1310 can be reversed with respect to the base arrangement 1100 and the aligning formation 1200. For example, the spigot 1320 may be attached to the base arrangement 1100, and the socket being associated with the aligning formation 1200.

[0084] It will further be appreciated by those skilled in the art that the coupling arrangement 1300 could comprise a wide variety of configurations, including but not limited to a sliding formation; a sliding formation with a tightening mechanism, a tightly fitting sliding formation, a threaded formation; and/or a bayonet-type formation.

[0085] It is anticipated that, once the coupling arrangement 1300 has been used to set the height of the aligning formation 1200 from the base support, as will be discussed in more detail below, the coupling arrangement 1300 will be locked in that preferred position, to prevent the aligning formation 1200 being accidentally displaced. In the preferred embodiments shown in figures, the coupling arrangement 1300 comprises locking formations in the form of an aperture or hole 1340 configured for receiving a fastener 1342 (shown in FIG. 3) such as a screw or nail, which can be inserted into the spigot 1322 lock the base arrangement 1100 and aligning formation 1200 in a selected position operationally.

[0086] In a preferred embodiment shown in FIGS. 11 and 12, the locking formations include a pair of ridges 1350 extending vertically along the socket 1330. It is envisaged that a screw may easily be screwed through the socket 1330, using the pair of ridges 1350 as a guide.

[0087] It is anticipated that the hole 1340 could be replaced by a recessed slot (not shown) in an alternative embodiment.

[0088] It is further anticipated that alternative means for locking the coupling arrangement can be provided, for example in the form of a bonding resin or a more complex locking arrangement. However, the illustrated embodiments are preferred for reasons of reduction of complexity and cost.

[0089] In addition to the spigot 1320, the aligning formation 1200 shown in the figures comprises a disc 1220 defining a flat alignment surface 1230, against which the settable material 3000 is aligned in operation at an aligned surface.

[0090] In a preferred embodiment, the aligning formation 1200 comprises zones of engineered weakness 1210. In the embodiment shown in FIGS. 4-6, the zones of engineered weakness 1210 are configured as a slot in the outer wall of the spigot 1320 above the external threaded formations 1322. The zones of engineered weakness 1210 render the aligning formation frangible along those zones, and allowing the aligning formation 1200 to be broken off at predetermined locations or lines by application of force to the aligning formation 1200 to thereby remove evidence of the settable material aligning arrangement located in the settable material 3000 after it has set, as will be discussed in more detail below.

[0091] As shown in FIGS. 4-6, in order to assist in the rupturing of the zones of engineered weakness 1210, the aligning formation 1200 comprises engaging formations in the form of a pair of apertures 1222 in the disc 1220. The apertures 1222 are configured for engagement by a tool—for example a tool comprising two protrusions configured for snug engagement in the apertures 1222, and which includes a lever arm for applying torque to the aligning formation 1200 about a vertical axis to thereby cause the zone of engineered weakness 1210 to rupture, and allowing an upper part of the aligning formation 1200 to be removed after the settable material 3000 has set. In this way, the base arrangement 1100 and the lower portion of the aligning formation 1200 are hidden within the set settable material 3000, and no evidence of their existence shows in the aligned surface of the settable material 3000 except for a small hole which can be filled in with a small amount of additional settable material 3000. It is envisaged that the upper part of the aligning formation 1200 above the zones of engineered weakness can be removed during the pour, or once the settable material has at least partially set.

[0092] It is further envisaged that more than one zones of engineered weakness 1210 can be provided along the length of the aligning formation 1200, as shown in FIGS. 9 and 10. In the aligning formation 1200 shown in FIGS. 9 and 10, the additional zone of engineered weakness 1210 can be used for reducing the overall length of the aligning formation 1200 before connecting the aligning formation 1200 to the base arrangement 1100 using the coupling arrangement 1300. In this way, a single piece aligning formation 1200 can be used for application in pouring a wide range of concrete floor widths.

[0093] In another embodiment shown in FIGS. 9 and 10, it is envisaged that the engaging formations could, for example be a star shaped or linearly shaped recess 1224 configured for engaging with a screwdriver or the like.

[0094] It is anticipated that the aligning formation 1200 will preferably be composed of plastic and integrally moulded in one piece in preferably an injection moulding process, although other moulding processes are also envisaged. Similarly, it is anticipated that the base arrangement 1100 will be composed of plastic and integrally moulded in one piece in a moulding process. However, in an alternative embodiment, it is envisaged that either of the aligning formation 1200 or the base arrangement 1100, or both, can be composed of any other suitable material, including but not limited to aluminum, steel, glass or wood.

[0095] It is further envisaged that either or both of the aligning formation 1200 or the base arrangement 1100 can be integrally moulded by means of injection moulding, rotary moulding or any other suitable moulding. In addition, it is envisaged that either or both of the aligning formation 1200 or the base arrangement 1100 can be cast in a mould, or printed in a 3 dimensional printing process.

[0096] As mentioned previously, the base arrangement 1100 comprises the socket 1330 of the coupling arrangement 1300. In addition, the base arrangement 1100 comprises a base formation 1110, shown in FIGS. 4-6 as an annular ring 1116 and in FIGS. 1-3 as linear tabs or strips 1114. The annular ring 1116 defines a flat surface for abutment against the support base 2000. The annular ring 1116 further defines fastening formations in the form of apertures 1112 for receiving fasteners 1117 such as screws or nails which may be fastened into the support base 2000 to secure the base arrangement 1100 to the support base 2000 before pouring of the settable material 3000. It is anticipated that alternative fastening formations can be provided, such as recesses, slots or the like.

[0097] In the preferred embodiment shown in the figures, the base arrangement 1100 further comprises a plurality of legs 1120 extending from the base formation 1110. The legs 1120 are configured to support the socket 1330 of the coupling arrangement 1300. It is envisaged that in an alternative embodiment (not shown) the socket 1330 could extend directly from a base formation such as a flange, however the use of an open structure, such as that shown in the figures, is preferred as it allows settable material to penetrate in between the legs 1120, and to set in this position, in order to permanently secure the base arrangement 1100 in position and bolster the strength of the floor once it has set. In this way, the integrity of the floor is not compromised by a reduction in strength around the base arrangement 1100. In addition, it is envisaged that the fire resistance and/or soundproofing of the poured floor will also not be compromised.

[0098] In another embodiment shown in FIG. 13, it is envisaged that the base arrangement 1100 can include lugs 1118 that extend downwardly in operation from the base formation 1110. The lugs 1118 are preferably configured with an aperture thousand 119 or recess in order to receive the fasteners 1117 in operation. In this way, the entire length of the base formation 1110 will not be visible from underneath the concrete slab once it is poured.

[0099] Further, and as shown in FIG. 13, it is envisaged that the settable material aligning arrangement 1000 can include one or more holding formations 1400 configured for holding elongate or any other required structures such as water pipes, electrical conduits, networking conduits, reinforcing bars, and mesh or other similar reinforcement, that are to be installed in the same construction, at a distance from the support base when concrete is being poured or applied in operation. In this way, the settable material aligning arrangement 1000 can provide a dual function of facilitating the aligning the plane of the concrete floor, and facilitating the securing of conduits 400000 and the like during pouring of the concrete floor as will be described in more detail below. The holding formations 1400 are preferably shaped as a preferably V shaped recess 1410 defining inner tapered surfaces that are configured for receiving a conduit from a vertically superior position. The holding formations 1400 preferably also comprise at least a pair of resilient clipping formations 1420 for securing the conduit in place once it has been received. The inner tapered surfaces of the recess 1410 allow for conduits of variable sizes to be received within the recess 1410.

[0100] In a preferred embodiment the holding formations 1400 are integrally moulded with the base arrangement 1100. In another embodiment (not shown) the holding formations 1400 can be integrally moulded with the aligning formation 1200, although this is not preferred. [0101] In Use

[0102] In use, it is anticipated that base arrangements 1100 will initially be secured to the support base 2000 by inserting fasteners such as pegs, screws or nails through apertures 1112 into the support base in order to securely fasten each of the base arrangements 1100 to the support base 2000. It should be noted that the support base can be earth, into which such fasteners can be driven, or could be wooden shuttering, or a wall.

[0103] Once the base arrangements 1100 have been fastened to the support base 2000, an aligning formation 1200 will be screwed into each of the base arrangements 1100. At this stage, a laser alignment device and/or tape measure may be used in order to set the alignment of the alignment surface 1230 at the aligned surface level of the floor to be poured, and in the same plane as each other.

[0104] Once the aligning formation is 1200 have been set at the correct distance from the support base, these are locked in position by inserting a fastener such as a screw or nail (not shown) through hole 1340 and into the spigot 1320 of the coupling arrangement 1300 in order to ensure that the distance of the aligned surface 1230 from the support base 2000 does not change.

[0105] After this, the settable material 3000, (which can be, for example, material including but not limited to concrete, cement or screeding and as shown in FIGS. 7 and 8 as 3000) is poured onto the support base 2000 up to a level flush with the flat aligned surface 1230 of the aligning formation 1200. Levelling tools such as a concrete vibrator and/or a straight flat plank or levelling tool (not shown) can be used to help the settable material 3000 settle and penetrate into the base arrangement 1100. In a preferred embodiment, each settable material aligning arrangement 1000 will be installed at a distance from each other that is slightly less than the length of any such levelling tool that is to be used. The levelling tool can then be rested between two of the settable material aligning arrangements 1000 to test the level of the aligned surface of the floor being poured.

[0106] Once the settable material 3000 has set sufficiently to allow access to the settable material aligning arrangements 1000, a tool such as the one described above can be used to apply a talk to the aligning formation 1200 to fracture or rupture the zones of engineered weakness, and remove the upper portion of the aligning formation, leaving a small hole H as shown in FIG. 8. The small hole H can be filled in by judicious application of a small amount of filler material, resulting in a level poured floor.

[0107] It will be further appreciated by those skilled in the art that the settable material aligning arrangement 1000 need not necessarily be used to align the alignment surfaces in a single coplanar plane that is parallel to the support base. Instead, it is envisaged that slopes and undulations in the aligned surface can be created accurately and smoothly by setting the aligning formation of the settable material aligning arrangement 1000 at required various distances from the support base.
