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 - 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.
