Description
- The present invention relates to slab edges. In particular, the present invention relates to balcony edges.
- Concrete slabs, such as those found on balconies, have limited lifespans. They are built according to specifications which should provide a decades long life span. Unfortunately, often as a result of environmental conditions, the balconies must be replaced within 8-12 years. The process of re-finishing is labour, resource and time intensive for those re-furnishing the balconies. The re-furnishers must:
-
- set up scaffolding in order to access the balconies;
- employ impact tools (e.g. jack hammers) to remove the damaged balcony portions while at the same time preserving any existing reinforcing bars within the slab structure; and
- set up form work to pour re-finishing concrete.
- Also this process often times significantly inconveniences the individuals who use the balconies. The noise and dust created is often intolerable. The dust generated can sometimes permanently damage personal possessions.
- The remains a need for a system and method for finishing a slab edge which mitigates or obviates at least some of the above-presented problems.
- A slab edge casing for finishing a slab edge is provided. The casing comprises a face which defines a finished slab edge for an unfinished slab edge; and, a base which extends from the face. The base is connectable to one of a slab face that is adjacent the unfinished slab edge or is registerable with the unfinished slab edge. The face and base have respective inside surfaces that define a form into which concrete is poured and allowed to cure. In one embodiment, one of the face and base also comprise a reinforcing element mount for receiving a reinforcing element that extends from the unfinished slab edge.
- The slab edge may be a balcony edge.
- A kit for finishing a slab edge is provided. The kit comprises a casing, which in turn comprises a face which defines a finished slab edge for an unfinished slab edge and a base that extends from the face. The base may be connectable to a slab face adjacent the unfinished slab edge or registerable with the unfinished slab edge. The face and base having respective inside surfaces that define a form into which concrete is poured and allowed to cure. The casing also comprises a brace mount positioned on one of the inside surfaces. In one embodiment, one of the face and base comprises a reinforcing element mount for receiving a reinforcing element extending from the unfinished slab edge.
- The kit also comprises a reinforcing element that is securable to the unfinished slab edge. The reinforcing element also comprises a brace mount. The kit also comprises a brace, extendable between the reinforcing element brace mount and the casing brace mount, and connectable to the respective mounts.
- In one embodiment, the reinforcing element, when secured to the unfinished slab edge, extends from the unfinished slab edge to at least a terminal anchor point that corresponds to the finished slab edge.
- The kit also comprises a brace, which is extendable between the reinforcing element brace mount and the casing brace mount, and connectable to the respective mounts.
- A method for installing a slab edge is also provided. The method comprises the steps of:
- securing a reinforcing element into the unfinished slab edge
- connecting a casing to the reinforcing element. The casing defines the finished slab edge and defines a form into which concrete is poured and allowed to cure.
- and, pouring the concrete into the form and allowing the concrete to cure. The casing remaining in position after the concrete has cured.

Deflection is kept at a minimum in order to maintain the visual presentation of thefinished slab edge 15. - PVC, as a material for casing 11 construction, offers a number of advantages over FRP. One advantage is that PVC can be welded on site (in addition to being glued or cemented, as may also be required). Welding permits on site customization of the
casing 11. It also reduces the number of welding plates that are required to connect casing pieces together, as in the corner portion of the finished slab edge, for example. An additional advantage of using PVC is that theface 13 andbase 19 may be formed separately and welded on site to form thecasing 11. - An embodiment of the present invention may alternately be characterized as a kit for finishing as unfinished slab edge.
