Abstract (en)
The device has a movable part (13) sliding in longitudinal direction in a fixed part (12) to increase volume of a parallelepiped longitudinal box (15) by deployment or extension. The movable part has length equal to half of length of the fixed part of the box. A handle (14) is placed on the movable part to facilitate sliding of the movable part inside the fixed part. Material used for realization of the movable and fixed parts is made of plastic, wood and/or metal. An independent claim is also included for a method for formation of reservation during construction of a concrete wall of a building.
