Positioning device and method for producing a reinforced construction material body

A positioning device (20) for positioning a reinforcement body (21) having reinforcement elements (23) that cross one another in a formwork (22), the positioning device comprising:

• a main body (27), upon which at least one first holding part group (29) and at least one second holding part group (30) are arranged, wherein each of the first and second holding part groups (29, 30) comprise at least one holding part (31), and wherein the at least one holding part (31) of the first holding part group (29) is movable between a holding position (I) and a release position (II) using an actuation device (46),
• wherein in the holding position (I) the holding parts (31) of the first and second holding part groups (29, 30) are configured to individually act on an associated reinforcement element (23) of the reinforcement elements of the reinforcement body (21) at a respective location of engagement (56) thereof,
• and wherein in the release position (II) the holding parts (31) of the first and second holding part groups (29, 30) allow movement of the positioning device (20) relative to the reinforcement body (21).
