Definitions

  • the present invention relates to an apparatus for forming the edge of a concrete floor slab panel, a concrete floor slab panel comprising the apparatus, a concrete floor comprising the apparatus, a method of manufacturing a concrete floor slab panel and a method of manufacturing a concrete floor.
  • Concrete floor slabs are generally cast as adjoining slab panels and each slab panel is cast inside a formwork; this formwork defines a space in which to cast the concrete.
  • the formwork may be constructed from timber, steel, aluminium, plastic or the like.
  • the formwork may be removable, which means it is removed after the concrete has cured.
  • the formwork may be leave-in-place formwork, which forms part of the resulting concrete structure, for example by providing at least part of an edge of a resulting concrete slab panel.
  • the formwork generally comprises one or more upright elongate divider plates, which the concrete is cast against.
  • the divider plates ensure that the concrete is contained within the desired space.
  • the divider plates When a number of floor slab panels are cast next to one another to form a concrete floor or slab, the divider plates generally sit in between adjacent slab panels, and dowels or dowel plates, attached to the divider plates, are used to connect the slab panels together in order to transfer loads across the joint.
  • the formwork should be positioned in such a way that the upper edges of the formwork coincide with the finished floor level (FFL), i.e. the level of the upper surface of the finished concrete floor slab.
  • FTL finished floor level
  • the slab and formwork rest on a subbase. If the subbase level (SBL) varies, the formwork will rest on the subbase's highest point. Because of this, it is common practice in casting concrete floors to allow around 15 - 25 mm for clearance. Concrete floor slab thicknesses are usually in the range of 150 to 200 mm. Formwork can be manufactured to desired thickness specifications, which is commonly done in 5 mm increments.
  • a divider plate can be suspended at the desired FFL using suspension means.
  • suspension means can, for example, be a jack, or pins may be placed on both sides of the divider plate and studs, which are commonly present in an apparatus for forming the edge of a concrete floor slab, may be welded to these pins, thus suspending the divider plate at the desired FFL.
  • wedges, adjustable feet and the like can be used to position the formwork in the desired manner against the subbase and hold it in place whilst the concrete is cast.
  • EP 1389648 describes an apparatus for forming the edge of a concrete floor slab panel, the apparatus comprising a divider plate with a plurality of apertures, dowels for engaging through the apertures and sleeves for applying to the dowels, in which the divider plate or dowel or top strip is provided with means to adjust the height thereof above the subbase.
  • These height adjustment means take the form of a supporting leg together with means for attaching the leg to the divider plate or dowel or top strip at a selected height.
  • the leg is positioned alongside the divider plate or dowel or top strip, and is attached to the divider plate or dowel or top strip either via a separate lock means, which is passed through a vertical slot formed in the leg or the divider plate or top strip, or via a dowel plate.
  • the effect of this set-up is to allow vertical movement of the joint assembly parallel to the leg, which therefore adjusts the height of the joint assembly relative to the subbase.
  • a gap is created between the subbase and the divider plate.
  • FR 2964131 describes a formwork height adjusting device which comprises a support base, a divider plate, a backplate, and spaced pairs of brackets. The height of the divider plate above the support base can be adjusted by sliding it up or down relative to the backplate and the spaced pairs of brackets.
  • an apparatus for forming an edge of a concrete floor slab panel laid on a subbase comprising:
  • a divider plate for bounding a side of the slab panel, the divider plate having first and second faces; and an elongate extension, securable along the first face of the divider plate, for sliding extension to an extended position in which the extension bridges a gap between the divider plate and the subbase in use;
  • the apparatus contains no component which, in use, attaches directly to the second face of the divider plate and which can extend beyond a lower edge of the divider plate into the gap between the divider plate and the subbase.
  • extension means that the extension has an elongate shape, the longitudinal axis of which is, in use, positioned substantially parallel to the longitudinal axis of the divider plate, and hence of the apparatus.
  • curable along the first face of the divider plate means that elongate extension can be secured to the divider plate at two or more locations along the length of the first face of the divider plate.
  • the extension can be moved up and down relative to the divider plate, which allows the height of the apparatus above the subbase level to be adjusted.
  • the apparatus therefore allows a range of different formwork heights to be achieved, which can be continuously variable, by using a single size of divider plate, instead of requiring a large number of different sizes of divider plates; the different formwork heights are achieved simply by adjusting the position of the elongate extension relative to the divider plate.
  • the apparatus of the invention can therefore allow much greater flexibility than known types of formwork and can allow distributors to stock a much smaller number of divider plate variants.
  • the production methodology can be changed from 'make to order' to 'make to stock' which allows a quicker response time to customers.
  • the apparatus of the invention can achieve a desired finished floor level (FFL) to a high level of precision; the observed variation is in the order of mm.
  • Known systems commonly rely on the clamping force of bolts and nuts to support the weight of the divider plate and hold it in position; in FR 2964131, for example, the divider plate is clamped in between spaced pairs of brackets which are held together with bolts and nuts.
  • the divider plate is prone to sliding down during the finishing process, when concrete finishing equipment such as heavy ride-on power trowels traverse across the top of the joint whilst the concrete is still uncured.
  • the resulting FFL is frequently lower than intended, or varies along the length of the divider plate.
  • the apparatus of the present invention can achieve a desired finished floor level (FFL) to a much higher level of precision, i.e. accurate to within fractions of a mm.
  • the apparatus according to the first aspect of the invention can be easier to operate than existing apparatus in this field.
  • support means which can include suspension means such as, for example, a jack
  • the position of the extension relative to the divider plate can, for example, be adjusted simply by tapping the extension down to the subbase level, or if the extension is attached to the divider plate via a loose fit it can automatically drop down to the subbase level.
  • the apparatus can enhance the ease with which concrete floor slab panels can be produced, can enhance the performance characteristics of the resulting concrete floor slabs, and can eliminate the need to trim off concrete spillage, which can save time and reduce waste management costs on site.
  • the extension is an essential element of the present invention.
  • the extension is obviously suitable for putting the invention into effect.
  • the elongate extension comprises at least an elongate side wall and an elongate foot.
  • the elongate extension has a substantially L-shaped cross-section.
  • the elongate extension further comprises an elongate return edge on the elongate foot, resulting in an elongate extension with a substantially J-shaped cross-section.
  • the elongate extension has a substantially C-shaped cross-section.
  • the position of the extension relative to the divider plate can be adjusted in a continuous manner. This allows the height of the formwork relative to the subbase to be adjusted to any desired height, within the range to which the extension is adjustable relative to the divider plate.
  • the position of the extension relative to the divider plate can be adjusted in a stepwise manner. The steps can, for example, be arranged to be set at known intervals which can help in aligning different sections of formwork without the need to take measurements.
  • At least one of the divider plate and the extension comprises members adapted to engage with the other. These members can, for example, ensure that the extension stays attached to the divider plate, ensure that the extension is held in position relative to the divider plate, and/or prevent the divider plate and extension from slipping relative to each other.
  • the divider plate comprises members adapted to engage with the extension.
  • the extension comprises members adapted to engage with the divider plate.
  • the extension is movable between a stowed position and the extended position and, in the stowed position, the extension cooperates with the divider plate to provide a frictional resistance to sliding extension.
  • This stowed form can make the apparatus more convenient to store, transport and handle.
  • the extension is movable between the stowed position and the extended position along a movement path and the divider plate and the extension are arranged to cooperate such that the frictional resistance varies along the movement path.
  • the movement path comprises a first section of greater resistance in which extending movement of the extension under gravity is prevented and a second section of reduced resistance in which extending movement of the extension may occur under gravity.
  • the extension may for example be attached to the divider plate via a loose fit, such that, in use, the extension can drop down to the subbase under gravity while remaining attached to the divider plate.
  • the divider plate and the extension are arranged to cooperate such that, when the extension is in the stowed position, the extension and the divider plate are held together by friction means to resist extending movement, but if the extension is extended by a predetermined distance, the extension can, in use, drop down to the subbase under gravity while remaining attached to the divider plate.
  • interference members such as small embossed 'pips', which protrude from the elongate extension near the lower end of the elongate extension and interfere with the mating face of the divider plate, thus causing an interference fit when the elongate extension is in its stowed position.
  • the divider plate and/or the extension contains a substantially vertical slot adapted to receive mechanical fastening means.
  • the divider plate contains a substantially vertical slot adapted to receive mechanical fastening means.
  • the elongate extension contains a substantially vertical slot adapted to receive mechanical fastening means.
  • the extension is arranged to be attached to the divider plate via mechanical fastening means.
  • the mechanical fastening means is a rivet.
  • Other mechanical fastening means can, for example, include a nut and bolt, and a screw, a threaded stud (along with a nut) welded to either the divider plate or elongate extension, a cable-tie, and a spring loaded compression type fastener.
  • the apparatus is arranged to be securable to the subbase. This arrangement makes the apparatus easier to operate, since it allows the concrete to be cast without the risk of the apparatus shifting in position (in a substantially horizontal direction) in the process. This can enhance the ease with which concrete floor slabs can be produced.
  • the apparatus further comprises a pin; and a wedge; wherein, in use, the pin can be placed in the ground on the same side of the divider plate as the elongate extension, and the wedge can be placed between the pin and the elongate extension and/or the divider plate, in order to secure the apparatus to the subbase in the desired location.
  • This arrangement allows the apparatus to resist the concrete thrust caused by concrete cast on the other side of the divider plate from the pin and wedge, which allows the concrete to be cast without the risk of the apparatus shifting in position (in a substantially horizontal direction) in the process.
  • the wedge which can be placed between the pin and the elongate extension and/or the divider plate, can be of any shape, as long as it allows the apparatus to be secured to the subbase in the desired location.
  • the range over which the extension can be moved relative to the divider plate is a range of about 50 mm. In use, this movement would generally be in a substantially vertical direction. Since the height of a concrete floor slab is usually in the range of 150 to 200 mm, the range of movement of about 50 mm can allow the full range of common floor slab heights to be achieved with a single size of apparatus.
  • the divider plate is formed from a metal such as, for example, steel. This can result in a divider plate of high mechanical strength, capable of withstanding the forces acting upon it during the casting of concrete.
  • the extension is formed from a metal such as, for example, steel, or from plastic. In an embodiment, the extension is formed from steel.
  • the extension is formed as an elongate extrusion.
  • the elongate extrusion has a substantially constant cross-section along its length.
  • the extension comprises a longitudinal fold at the top edge and/or the lower edge of the extension.
  • a fold can, for example, be a longitudinal L-fold, a longitudinal V-fold or a Dutch fold (where the divider plate is completely folded back on itself).
  • a fold can strengthen the extension.
  • the divider plate can be conventional in construction, for example as EP 1389648 or similar.
  • the divider plate is an elongate flat section of material.
  • the divider plate comprises a longitudinal fold at the top edge and/or the lower edge of the divider plate.
  • a fold can, for example, be a longitudinal L-fold, a longitudinal V-fold or a Dutch fold (where the divider plate is completely folded back on itself).
  • Such a fold can strengthen the divider plate.
  • the divider plate comprises one or more apertures.
  • the apparatus further comprises one or more dowels or dowel plates for engaging through the one or more apertures. These act to connect the resulting concrete slab panels together and to provide a method of load transfer between adjacent slab panels.
  • the apertures suitable for receiving the dowels or dowel plates in the divider plate are located above the upper edge of the elongate extension when the extension is in its highest position relative to the divider plate (i.e. the extension is in its fully retracted form).
  • the extension may be castellated along its top edge such that it can accommodate the dowels.
  • the apparatus may comprise further components, which after casting of the concrete would sit at the surface of the concrete floor.
  • Such components include, for example, edge rails and top plates.
  • the apparatus further comprises edge rails, which may be supported by the divider plate.
  • the apparatus comprises two such edge rails adjacent to each other. The edge rails can provide protection to the arris of the cast slab panels and improve the longevity of the slab at the joints.
  • the edge rails may be arranged to mate with each other along linear or non-linear edges. In an embodiment, the edge rails are arranged to mate with each other along linear edges. In an embodiment, the edge rails are arranged to mate with each other along non-linear edges.
  • the apparatus further comprises top plates, which may be supported by the divider plate.
  • the apparatus comprises two top plates adjacent to each other, referred to as first and second top plates.
  • the top plates can provide protection to the arris of the cast slab panels and improve the longevity of the slab at the joints.
  • the apparatus comprises first and second top plates which are arranged to mate with one another along linear edges. In an embodiment, the apparatus comprises first and second top plates which are arranged to mate with one another along non-linear edges, such as, for example, shown in FR 2785632.
  • the apparatus further comprises first and second supports, the first support being attached to or attachable to the divider plate and to the first top plate, and the second support being attached to or attachable to the second top plate.
  • the first support comprises a facing edge which faces the second support, and the edge of the first top plate is offset from the facing edge of the first support, along the direction in which the top plates can move apart, so that, when in use between two shrinking concrete slab panels, the gap which opens up between the top plates is offset from the gap which opens up between the supports and the gaps do not overlap.
  • the apparatus when the apparatus is used as a joint between concrete floor slab panels, if, as the concrete shrinks, the first and second top plates move apart in the direction perpendicular to the longitudinal axis of the joint, the elongate gap which is formed between the first and second top plates is only as deep (vertically) as the first and second top plates.
  • This gap is offset from the gap which opens up between the supports, and which extends down to the subbase between the two shrinking concrete slab panels.
  • the gap which opens up between the first and second top plates is offset from the gap which opens up between the supports in the same axial plane.
  • the two gaps do not overlap, so this joint does not contain a continuous path from the surface to the subbase.
  • Shrinkage gaps can commonly be filled in with a filler rod and a sealant resin.
  • This is a labour intensive process, and it usually does not provide a final solution due to the long time it takes for concrete slabs to stop shrinking.
  • the filler rod and sealant resin are usually applied before the concrete floor slabs have stopped shrinking, and as they continue to shrink the gap can reopen since the sealant is unable to stretch enough to accommodate the larger shrinkage gap.
  • the sealant is costly and tends to age and requires removal before fresh sealant can be fitted.
  • the edge rails, top plates and/or supports further comprise anchor means for embedding in the concrete.
  • the anchor means become embedded in the concrete during curing and fix the edge rails, top plates and/or supports in position.
  • anchor means may also be welded to pins, placed on both sides of the divider plate, to suspend the divider plate at the desired finished floor level (FFL) before concrete is cast.
  • the pins would, of course, be placed or cut off in such a way that they do not stick out above the FFL.
  • This technique of suspending the divider plate at the desired FFL can be used as an alternative to or in combination with other support means, which can include suspension means such as, for example, a jack.
  • the edge rails, top plates and/or supports are attached together with yieldable fixings. These fixings fail under tension as shrinking occurs during the curing process and the edge rails, top plates and/or supports of adjacent slabs are drawn apart.
  • the yieldable fixings comprise low tensile bolts.
  • low tensile bolts are bolts formed from nylon, the threads of which will become stripped under shrinkage forces, or the shanks of which will fail under tension .
