Form drain for incorporation into a building foundation
View Patent ↗An improved building foundation form system that includes an integral drain and a spacer bar with engagement lugs at each end adapted to engage a T-shaped engagement channel formed in each of the form surfaces of the inner and outer forms.
1. A building foundation form system, comprising:
a. first and second form segments of predetermined length and adapted for positioning in laterally spaced, non-contacting, parallel relation to one another, and each having a form face, drain face, top surface and bottom surface all of which collectively define a hollow interior drain;
b. said form faces each including an indentation formed therein;
c. a spacer bar having first and second ends adapted to securely engage both of said indentations, thereby securely interconnecting said first and second form segments, wherein said spacer bar's first and second ends comprise first and second connecting lugs, respectively, said first and second connecting lugs comprising a generally T-shaped projection.
2. The form system of claim 1 , further comprising a connector element for joining two of either of said first and second form segments in end-to-end relation and providing continuous drainage between said joined form elements.
3. The form system of claim 1 , further comprising first and second stiffening members positioned within and extending co-axially with said first and second form segments, respectively.
4. The form system of claim 1 , wherein said top surface is non-perforated.
5. The form system of claim 1 , wherein said bottom surface is perforated.
6. The form system of claim 1 , wherein said drain face is perforated.
7. The form system of claim 1 , wherein said form face is non-perforated.
8. The form system of claim 1 , wherein said indentations are elongated channels.
9. The form system of claim 8 , wherein said elongated channels extend about the length of said segments.
10. The form system of claim 9 , wherein said channels are T-shaped.
