Abstract
An embodiment configured according to principles of the invention includes a plate defining a hexagon having a base parallel with joint between concrete slabs. Another embodiment includes a hexagon-shaped plate having an elastomer-coated first portion and a second portion, and a form having a slot configured to closely receive the second portion. A further embodiment includes a plate having compressive and/or resilient edge banding disposed on a plate edge that is not parallel to the joint. Apparatuses and methods for retro-fitting existing concrete stabs for transferring a load with a new adjacent concrete slab also are disclosed.
Claims27
Apparatus for transferring a load between a first concrete slab and a second concrete slab, defining a joint, comprising:
- a plate or dowel;
- and
- edge banding disposed on a surface of the plate or dowel.
Apparatus for forming concrete comprising:
- a form having a slot configured to closely receive a plate;
- a plate having a first portion and a second portion;
- and
- a coating and/or edge banding disposed on said first portion;
- wherein:
- said coating at least initially adheres to said plate;
- and
- said coating and/or edge banding has a thickness configured to prevent said first portion from passing through said slot.
Method of forming concrete comprising:
- providing a plate having a first portion and a second portion and edge banding disposed on a surface of the first portion;
- providing a form having a slot configured to closely receive the second portion;
- inserting the second portion in the slot;
- positioning the form to receive concrete;
- pouring a volume of concrete on the form and the first portion;
- curing the volume of concrete and defining cured concrete;
- and
- removing the form from the cured concrete,
- wherein the plate remains in the cured concrete.
Method of locating a plate in a form for forming concrete comprising:
- providing the form with a slot configured to closely receive a plate having a first portion and a second portion;
- and
- coating and/or edge banding the first portion;
- wherein:
- the coating at least initially adheres to the plate;
- and
- the coating and/or edge banding has a thickness configured to prevent the first portion from passing through said slot.
Method of installing a load transfer apparatus in a concrete slab comprising:
- developing a recess in the concrete slab;
- and
- introducing a first portion of a load transfer apparatus in the recess;
- wherein the first portion has edge banding and/or an elastomer coating.
