ABSTRACT:
A slab joint form structure for pouring of a concrete slab with a continuous shear joint including a pair of longitudinally superimposed edge forms, a flat slab joint shear bar positioned in a generally horizontal plane and lying longitudinally between the superimposed edge forms and extending longitudinally thereof, the superimposed wedge forms being engaged with opposite sides of the flat slab joint shear bar, wedge brackets positioned in superimposed stacked relation, the wedge brackets being attached to the edge forms in superimposed aligned relation with the flat slab joint shear bar being between the superimposed brackets, the wedge brackets providing superimposed wedge pockets, a stake located in the superimposed wedge pockets for ground embedment, a locator positioned between one of the edge forms and the shear bar for positioning the shear bar in a proper fixed position relative to the edge forms and leaving an inner edge projected inwardly a predetermined selected distance beyond the closed sides of the edge forms for being embedded in concrete after the concrete has been poured against inside wall faces of the edge forms.
