Claims25
A connecting member for connecting together left and right parallel sheets to make a form for receiving concrete, comprising:
- a connecting web defining left and right ends;
- transverse attachment flanges adjacent the left and right ends of said connecting web;
- said connecting member including upper and lower connecting mechanisms, so that, when another connecting member is placed directly above said connecting member, the upper connecting mechanism of said connecting member cooperates with the lower connecting mechanism of the other connecting member lying above it so as to hold the connecting members together.
In a form for receiving concrete, comprising left and right parallel walls having inner and outer surfaces and a plurality of connecting members which hold said left and right walls a fixed distance apart;
- wherein said walls define slots which receive the connecting members, and the connecting members terminate at their respective slots, before reaching the outer surfaces of said left and right parallel walls;
- and further comprising:
- visual indicators on the outside of said left and right parallel walls to show where the connecting members are located;
- wherein said connecting members extend substantially the full height of said form so that, when several of these forms are stacked together and concrete is poured into them, the connecting members provide a structure to which wall finishes can be attached along the full height of the wall.
