Abstract
Description
- This invention relates to the forming of concrete floor slabs, particularly the forming of the edges of the slabs, and to providing improved means for load transfer between adjacent slabs.
- It is well known that concrete floor slabs are cast in place inside a formwork commonly constructed from timber. The formwork provides an edge and defines a space in which to cast the concrete; it does not, however, provide support or protection during the casting or curing process or throughout the lifetime of the slab.
- When casting slabs using the known formwork it is difficult to arrange the formwork such that the upper edge thereof coincides with the intended level of the upper surface of the slab. Packing pieces such as wedges are used in order to adjust the height of the formwork in which to cast the slabs.
- Once cast, concrete slabs are prone to shrinkage during curing which causes the edges of the slabs to separate and expose the upper edge or arris of each individual slab to damage from loads, such as from lorries, passing across the joint.
- Individual slabs often support heavy loads passing from one slab to another and therefore require a method of load transfer between adjacent slabs in order to prevent breakdown of the joint between adjacent slabs caused by stresses induced by such loads. Typically round or square steel rods, commonly known as dowels, are embedded in the concrete to extend at 90 degrees across the formed joint and connect the slabs together in order to transfer a load from one slab, across the joint, to the adjacent slab. However, when the slab shrinks during curing, the dowels embedded in the concrete themselves create stresses in the slabs due to differential shrinkage between adjacent bays of concrete, this becoming a further cause of cracks in the slabs particularly at corners. In any event, a load transferred by a dowel results in concentrated zones of stress immediately above the dowel, with consequential risk of edge cracks occurring.
WO99/31329 WO99/31329 - It is therefore an object of this invention to provide height-adjustable apparatus for forming the edges of concrete floor slabs, to provide means for load transfer between adjacent slabs and preferably to protect the arris of the slab after casting of the concrete.
- In one aspect the invention provides apparatus for forming the edge of a concrete floor slab, the apparatus comprising a divider plate formed with a plurality of apertures, dowels for engaging through the apertures and sleeves for applying to the dowels, in which the divider plate is provided with means, in use, to adjust the height thereof above the ground.
- The divider plate is preferably formed from metal and is intended to be left in place between slabs cast on each side thereof. The divider plate may be supported above ground level on longitudinally spaced apart feet, the feet being operatively connected to the height-adjustment means.
- The apertures formed in the divider plate may be any shape and size in order to receive the dowels, which may be round, square, or formed as flat plates, for example rectangular or trapezoidal plates. The dowels may comprise means for receiving and securing the height-adjustment means, or the height-adjustment means may be attached direct to the divider plate. The sleeves for applying to the dowels will correspond internally with the shape of the dowels used, in order to provide relative two-way horizontal sliding movement and a tight fit vertically. The sleeves are preferably formed from a plastics material to reduce the coefficient of friction between the dowels and sleeves The sleeves may be formed with lug or ridge members which allows them to be retained in place within the slabs cast.
- The means for adjusting the height of the divider plate above ground level may comprise a leg and means for attachment of the leg to the divider plate at a selected height. The leg may be attached direct to the divider plate by a lock means which is passed through a vertical slot formed either in the leg or the plate to provide for height adjustment. However, in another embodiment, the leg may be screw threaded and can either be threaded or passed through the dowel or through a collar attached to the dowel with means for altering the position of the dowel along the length of the leg. Where the leg is threadedly engaged, such means may comprise a slot or socket to receive a suitable driver to rotate the leg. Where the leg is passed through, such means may comprise adjustment nuts and suitable washers. In either case, the effect is to move the dowel vertically along the leg in order to adjust the height of the apparatus through the engagement of the dowel with the divider plate.
- The apparatus may further comprise edge rails which are preferably supportable by the divider plate to provide protection to the arris of the cast slabs. The edge rails may further comprise anchor means which become embedded in the concrete during curing and which fix the edge rails in position. The edge rails of adjoining slabs are preferably attached together with yieldable fixings wherein, as shrinking occurs during the curing process and the edge rails of adjacent slabs are drawn apart, the fixings yield to allow for the movement. The yieldable fixing may comprise low-tensile bolts, for example formed from nylon, the threads of which will become stripped under shrinkage forces. However, at least some of the bolts may be steel to hold the edge rails firmly together until after a first slab has been cast on one side of the apparatus, the nuts then being removed from the other side before the second slab is cast. The fixings for the edge rails are preferably located in holes formed through the rails, the fixings carrying a longitudinally-split resilient steel or plastics sleeve to take up any free space between the fixings or the shanks thereof and the holes, to ensure that adjacent rails are accurately placed in position. Optionally, the height-adjustment means is attached to the edge rails or to the anchor means thereof.
- Apparatus according to the invention can be used to form prefabricated four-way intersections, three-way "T" intersections, corner units and loading dock units.
- Embodiments of the invention will now be described by way of example with reference to the accompanying drawings, in which
- Figure 1 is a cross section of one form of apparatus according to the invention forming a joint between two adjacent concrete slabs;
- Figure 2 is a perspective view of parts of the apparatus of Figure 1;
- Figure 3 is a cross section of the apparatus in Figure 1 once the slabs have cured, shrinkage has taken place and the joint opened;
- Figure 4 is a perspective view of an alternative form of apparatus including trapezoidal plate dowels according to the invention;
- Figure 5 is a perspective view of the apparatus shown in Figure 4 including diamond dowels;
- Figure 6 is a cross section showing the apparatus of Figure 4 in place between two cured slabs of concrete; and
- Figure 7 shows a general perspective view of apparatus according to the invention when arranged to form a four-way intersection.
- With reference to Figures 1 and 2, the apparatus shown generally at 10 is embedded in
concrete slabs divider plate 13 is disposed at right angles across feet 14 which are positioned on the ground. Thedivider plate 13 hasapertures 15 which receivetrapezoidal dowel plates 16, the median length of the dowel plates corresponding with the length of the apertures so that approximately half of each dowel plate protrudes through its respective aperture, the other half (having the longer edge) remaining protruding from the insertion side of the divider plate. Once thedowel plate 16 has been inserted through the aperture of thedivider plate 13, asleeve 17 formed withexternal ridges 18 is applied over the portion of the dowel plate which protrudes from the aperture and has the shorter edge. The upper end region of thedivider plate 13 is provided with aseating 19 which supports anedge rail 20 for theslab 12 which is itself attached to anedge rail 21 for theadjacent slab 11 by low-tensile bolts 22. Each edge rail is formed withanchors adjustable legs 25 which are attached to respective feet 14 and inserted throughholes 26 in thedowel plates 16 and secured therein bynuts washers 29, 30. In use, the height of the divider plate can be adjusted by the movement of thedowel plate 16 up or down theleg 25, by manipulation of thenuts rails - Once the pre-assembled apparatus has been put in place the slabs are cast and left to cure. During the curing process the slabs shrink and cause the edges of the slabs to become separated from one another.
- Figure 3 shows
slabs gap 31. Thebolt 22 has sheared to allow the separation of the adjacent slabs andanchors respective edge rails slabs dowel plate 16, which is attached toleg 25, is movable within thesleeve 17 in two horizontal directions but not vertically. - With reference to Figure 4, Figure 5 and Figure 6, a
divider plate 41, formed with an upturnedlower edge 42 for strengthening purposes, is supported ondetachable legs 43 attached to ground-engaging feet 44. Thedivider plate 41 carries a series ofvertical slots 45, thelegs 43 andfeet 44 being attached to selected slots withbolts 46 andnuts 47, shown as wing-nuts 48 in Figure 5. The height of the divider plate relative to the ground may be adjusted by virtue of relative movement between theslot 45 and thebolts 46. - As with the apparatus shown in Figures 1 to 3,
trapezoidal dowel plates 49, as in Figure 4, are passed through horizontal slots formed in the divider plate and sleeves 50 are applied from the other side of the divider plate, over the protruding portion of the dowel plates. Optionally, the dowel plates could be other shapes, for example rectangular or square, in the latter case being inserted through the divider plate such that opposite corners extend from the divider plate as triangular forms, as in Figure 5. - The upper edge of the divider plate carries
edge rails bolts 53 andnuts 54. The bolts, formed from nylon, carry a longitudinally-split sleeving 55 around the shank thereof to ensure that, with therails respective rails - With particular reference to Figure 5,
concrete slabs divider plate 41 and the concrete has cured. In the process, the concrete has shrunk and the edge rails 51, 52, secured to the respective slabs by the anchor pins 56, 57, have been drawn apart by shearing of the threads of thebolt 53 in thenut 54. Thedowels 49 have withdrawn slightly from the sleeves 50 as the slabs move apart. As with the apparatus shown in Figures 1 to 3, the edge rails 51, 52 could be longitudinally offset so that their ends, instead of being flush as shown in Figure 4, are staggered so that, when placed in end-to-end relationship with another divider plate and edge rails, the edge rails form a lap joint. - With reference to Figure 7, four
sets 71 to 74 of apparatus are shown intersecting orthogonally at a prefabricated joint 75 between four slabs. The four limbs of the joint 75 which are joined to respective divider plates with the edge rails forminglap joints sleeves 80, 81 and sets 72 and 73 have diamond-shaped dowel plates andsleeves set 71 is provided by means ofrods 84 welded to concrete anchor pins 85 and supported by legs 86 welded at the appropriate distance to achieve the desired height.Set 73 has screw-threadedlegs 87 engaged through holes in theplates 82 by nuts 88 andwashers 89. Set 74 has a separate height-adjustment jack arrangement consisting of a base 90 andleg 91 slidingly carrying an arm 92 temporarily attached to the edge rail and movable up or down by turning screw-threadedrod 93 vianut 94,captive nut 95 being welded to the arm 92 viaslider 96. The jack is used on the side remote from the first cast slab and removed before the second slab is cast.
