Device for temporarily positioning a frame to be connected securely to a concrete wall during construction of the concrete wall

A positioning device for positioning a frame between two parallel form panels of a wall form assembly when pouring concrete, the device comprising:

• a positioning plate adapted to be fastened to one of the form panels and having a planar positioning surface which abuts against the frame and which is adapted to be perpendicular to the form panels;
• two strip holders adapted to be disposed between the form panels, each of the strip holders being adapted to be coupled with either the positioning plate or said one of the form panels;
• and
• two seal strips adapted to be disposed on two sides of the frame between the form panels in such a manner that each of the strips is positioned between the frame and one of the form panels and each of which is held by a respective one of the strip holders so as to establish a liquid-tight seal between the frame and the form panels, such that an assembly of the frame and the seal strips defines, between the form panels, a concrete pouring space and a non-pouring space on two sides of the assembly, the positioning plate and the two strip holders being located in the non-pouring space;
• whereby concrete is to be poured into the concrete pouring space.
