RAP-I-FORM Installation Instructions

 

1. Chalk building line on footing
2. Place clips on building line.
3. Set panels A & B and secure at corner. Then set panels C, D, & E, and continue along building line, making sure to place clips top and bottom 4-8” from end of each panel as shown. If desired, clips on joints may be nailed after placement of panel. (Exact spacing is not necessary.)

Caution: Always make certain there is a clip to hold the end of each panel regardless of where the panel joint may be.

Prenailing of clips: This will cause incorrect spacing and loss of time.

Note: With the RAP-I-FORM® system a level footing is not necessary, however, a flat footing surface will speed the form setting process and simplify alignment of the panels.

It is also imperative that the form clip be fully engaged to the bottom of the panel. An un-level footing could allow the form clip to drop below the edge of the panel restricting the ability of the form clip to capture the form panel. To correct the form clip alignment, nail form clip securely to the bottom of the form panel.

W = Wall Thickness
P = Panel Thickness

1. Footing forms in position using RAP-I-FORM® Clips & Stakes

2. RAP-I-FORM® Clips placed on building line, ready to set panels. Nail corner clips

3. Panel held by RAP-I-FORM® clips top and bottom, ready for grade, final alignment check and pouring concrete.

4. Proper clip spacing on joint, showing natural off-set of panel from corner start. Use same spacing top and bottom.

 

5. Sheet metal pan held in place by RAP-I-FORM® clips. Pan eliminates cutting of inside panels and provides starting point for stripping.

It's That Easy!

3/4" and 1-1/8" panel size is for reversible plywood panels.
1-5/8" size is for dimensional lumber.
2-1/4" size is for 5/8" plywood on a 2 x 4 frame.

RAP-I-FORM® shall not be responsible or liable for form failures where maximum clip spacing or recommended rate of pour has been exceeded. The clip spacings and rates of pour listed are the maximum permissible for each size clip.

RAP-I-FACTS!

The initial cost of RAP-I-FORM® forming system is 50% less than competitive systems when used with 1-1/8" HDO plywood. The RAP-I-FORM® system eliminated the need to drill panels, fabricate inside and outside corners, or the labor of handling forming lumber such as walers and base plates.
