Tool designed for restoration/repair of formwork props, and its usage

A tool designed for restoration or repair of at least one of formwork props or construction supports, including a tool housing, control and restoration parts, the tool comprising:

• a dilative operational part section, an inlet into a damaged formwork prop close to a location which is to be repaired;
• and
• a rotational part section, which is rotated around an axis of the tool clockwise or counterclockwise;
• wherein
• the dilative operational part section includes:
• at least two of several connected pipe-shaped elements configured to enable the dilative operational part section to enter into a damaged formwork prop;
• and extending an overall length of the tool:
• a stationary part, functioning as the tool housing;
• a bolt screw integrated into an ending of the stationary part and designed for the stationary part not to rotate with the rotational part section using a key attached to the stationary part by the bolt screw;
• wherein
• a head of the tool being designed to restore the geometry of the formwork prop to its initial position opposite a direction from the deformation force;
• wherein
• the rotational part section includes:
• a screwdriver designed for clockwise or counter clockwise rotation;
• the rotational part section being based on a screw mechanism connected with the screwdriver and, when using the screw mechanism, the rotational part section is connected with a pull/push wedge by the head of the tool;
• wherein
• the head of the tool includes:
• the wedge, connected with the screw mechanism of the rotational part section;
• at least one of several dilative/retractable plates, which, depending on the rotational direction of the screwdriver, are pushed or pulled by the wedge;
• and
• an elastics placed on the at least one of several dilative/retractable plates, the elastics performing the function of returning the at least one of several dilative/retractable plates to the initial position of the at least one of several dilative/retractable plates when the at least one of several dilative/retractable plates are loose,
• wherein
• the plates are configured so that, during the restoration of the geometry of the damaged formwork props or construction supports, the plates are expanded not centrically.
