Concrete slab corner support
A concrete slab corner support is a unitary corner support and reinforcement element for a concrete slab or the like. The corner support element is placed inside the corner of a form prior to pouring concrete therein to form a concrete slab. A corner support is placed in each corner of the form and affixed to the form with nails, or screws through break-away flanges extending outward from the upper end of the support. The corner support is an angle element forming two walls defined by a center angle bend and the outer edges thereof. A series of rod-like or finger-like anchors extend from the inner sides of the walls inwardly toward the middle of the form. These anchors help the corner support to remain attached to the pad or foundation when the process is complete. Once the concrete has set, the forms and bread-away flanges are removed.

BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to concrete corner protectors and supports. More particularly, the present invention relates to a concrete slab or column corner support having imbedded anchors.
2. Description of the Related Art
Many corners of concrete pads are damaged in the pouring process, prior to the concrete or other pourable setting material being hardened and put into use. Present corner supports and protectors are generally elongate angle elements, which are connected to cover the exposed corner with adhesive. These types of supports and protectors may easily deteriorate or be knocked away from the corner, leaving it exposed.
The breaking off of corners of poured and set concrete slabs, such as those used in housing, is a common problem. The corner of the slab may break years after building the structure, resulting in damage to brick or other materials resting on the corner. It would be desirable to provide a corner support for protecting and reinforcing the corners of poured concrete slabs. It would also be desirable that such a support be resistant to accidental damage and degradation, so as to provide reinforcement and support to the concrete slab over a period of years.
Thus a concrete slab corner support solving the aforementioned problems is desired.
SUMMARY OF THE INVENTIONThe concrete slab corner support of the present invention is a unitary corner support and reinforcement element for a concrete slab or the like. The corner support element is placed inside the corner of a form prior to pouring concrete therein to form a concrete slab. A corner support is placed in each corner of the form and affixed to the form with nails, or screws through break-away flanges extending outward from the upper end of the support. The corner support is an angle element forming two walls defined by a center angle bend and the outer edges thereof. A series of rod-like or finger-like anchors extend from the inner sides of the walls inwardly toward the middle of the form. These anchors help the corner support to remain attached to the pad or foundation when the process is complete.
Once the concrete has set, the forms are removed, the break-away flanges being removed with the forms, leaving the finished slab having, supported corners. The end result is a concrete foundation having a series of corner supports. The corner supports can be made from galvanized metal or any other material that is capable of withstanding the environment and the load and stresses encountered by the corner support.
These and other features of the present invention will become readily apparent upon further review of the following specification and drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTSThe present invention is an anchored concrete pad corner support and protector for use in the pouring of a concrete or other setting material within a form to form a slab.
Referring to
Angle plate 12 has outer vertical edges 28 oriented substantially parallel with angle plate bend 16. Anchors 30 are attached to the inner sides of angle plate sidewalls 14, preferably extending perpendicular therefrom and spaced vertically along vertical lines drawn approximately halfway between bend 16 and respective angle plate outer edges 28. The anchors 30 are offset along one sidewall 14 in relation to those along the other sidewall 14 so as to cross without interference (as shown in
The rods 32 are shown in

Additionally, the user may wish to secure anchor apertures 72 to the slab's rebar, post tension cable or similar reinforcement elements prior to the pouring of the concrete. Similarly, the anchor rods 32 of the embodiment shown in
The corner supports of the present invention are preferably made of corrosion resistant sheet and rod material of galvanized metal, however, other appropriate material may be employed in their construction.
The corner supports of the present invention may be of any desired length for applications such as foundations, pillars, and columns.
Further, in the alternative embodiment illustrated in
Additionally, at least one mid-plate anchor 110 is formed in walls 54, through stamping and pressing or similar conventional processes. The mid-plate anchor 110 provides for additional securement to the concrete near the corner bend 56. A plurality of mid-plate anchors 110 could be provided, depending upon the needs and desires of the user. Additionally, a stamped recess 120 could be formed along corner 56, providing an additional securement surface for the concrete of the slab C.
A recess 130 could also be formed in each wall 54, projecting inwardly, providing a further anchoring surface for the concrete. Recess 130 could be used alone or in combination with the alternative mid-plate anchors 110 and stamped recesses 120. Further, a plurality of recesses 130 could be provided.
It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
Claims
1. A concrete slab corner support for attachment to slab form corners, comprising:
- an elongated, vertically disposed angle plate having a pair of sidewalls, each said sidewall having an inner side and an outer side, said pair of sidewalls defining an angle plate bend, said elongated, vertically disposed angle plate having a lower end portion, an upper end portion, and outer vertical edges;
- a break-away fastener flange extending outward from at least one of said sidewalls and extending from said upper end portion thereof for attachment to the upper edge of the slab form; and,
- a plurality of spaced anchors extending inward from the inner side of at least one of said pair of angle plate sidewalls, whereby said concrete slab corner support is placed on the inner side of a corner of said slab form for pouring a concrete slab, said plurality of spaced anchors extending into said concrete slab, whereby upon the pouring and setting of the concrete slab, the form is removed, and said at least one fastener flange is broken away and removed.
2. The concrete slab corner support as recited in claim 1, wherein said plurality of spaced anchors are each elongated rods.
