T-Form ICF Configuration
Reward’s product line includes an 11″ T-form that provides a 6 inch concrete core for both the intersecting wall and the longitudinal wall. This insulating concrete form configuration will make the construction of a T-wall more efficient by eliminating cutting and bracing in comparison to manually constructing a T-wall with only straight forms.
Save Time with ICFs
The T-forms are shipped with both long and short sizes so that the forms will continue to be overlapped creating a running bond pattern.
Also, the 11″ T-form has additional plastic ties and EPS foam support at the back side of the wall intersection to reduce the bracing requirements.
When stacking forms, the T-form should be treated similarly to 90-degree corner forms. The corners and intersecting walls locations are defined by the plan design. The corners and T-forms should be placed at this location according to the plan. Then the forms are stacked to the middle between the corners and T-forms. Flip and alternate every other T-form course from long to short creating a running bond and eliminating a common seam at the T-intersection.
Reinforcement of T-Form
Place horizontal reinforcement with a 2′-6″ bend on each end at each T-form course. These bars should alternate each direction in the longitudinal wall at every other course and have a proper lap splice with the horizontal rebar in the wall. Concrete flowing around the corners of the intersecting wall will create great concrete pressures on the intersecting T-form and therefore the amount of bracing at this location must be taken into consideration.
When placing concrete at the T intersection, aim the concrete flow down the longitudinal wall letting the concrete flow itself into the intersecting wall. Have the concrete in the T-form wall build up slowly. Do not have the concrete flow from the intersecting “T” to the longitudinal wall.
