Formwork device equipped with a deviation- measuring device

A formwork device for an end of a panel of a molded wall, said formwork device extending along a longitudinal direction and comprising at least one first formwork element including:

• a base extending along the longitudinal direction, from a lower end to an upper end, and having an outer face which is planar as well as an inner face bearing a casing which extends along the longitudinal direction along the inner face, from a lower end portion of the base to an upper end portion of the base, said casing comprising a seal carrier extending along the longitudinal direction along the casing, the seal carrier carrying a seal;
• the formwork device further including:
• at least one measuring device adapted to determine at least one first deviation parameter representative of the deviation of the base with respect to a first vertical plane, said measuring device being movable with respect to the casing of the first formwork element along the longitudinal direction;
• and
• a signal-transmitting device connected to the measuring device to transmit the first deviation parameter to a reception station located at the surface;
• the formwork device further comprising:
• a second formwork element attached to the first formwork element, the second formwork element comprising:
• a base extending along the longitudinal direction, from a lower end to an upper end, and having an outer face which is planar as well as an inner face bearing a casing which extends along the longitudinal direction along the inner face, from a lower end portion of the base to an upper end portion of the base, said casing comprising a seal carrier extending along the longitudinal direction along the casing, the seal carrier carrying a seal,
• wherein the measuring device is movable with respect to the casing of the second formwork element along the longitudinal direction.

A formwork installation including:

• a formwork device for an end of a panel of a molded wall, said formwork device extending along a longitudinal direction and comprising at least one first formwork element including:
• a base extending along the longitudinal direction, from a lower end to an upper end, and having an outer face which is planar as well as an inner face bearing a casing which extends along the longitudinal direction along the inner face, from a lower end portion of the base to an upper end portion of the base, said casing comprising a seal carrier extending along the longitudinal direction along the casing, the seal carrier carrying a seal;
• the formwork device further including:

• wherein the reception station is connected to the measuring device via the signal-transmitting device of at least the first formwork element.

A concreting method comprising:

• introducing into a trench at least one formwork device for an end of a panel of a molded wall, said formwork device extending along a longitudinal direction and comprising:
• at least one first formwork element including:
• a base extending along the longitudinal direction, from a lower end to an upper end, and having an outer face which is planar as well as an inner face bearing a casing which extends along the longitudinal direction along the inner face, from a lower end portion of the base to an upper end portion of the base, said casing comprising a seal carrier extending along the longitudinal direction along the casing, the seal carrier carrying a seal;
• the formwork device further including:
• at least one measuring device attached to the casing and adapted to determine at least one first deviation parameter representative of the deviation of the base with respect to a first vertical plane;
• and
• a signal-transmitting device connected to the measuring device to transmit the first deviation parameter to a reception station located at the surface, putting concrete in the trench and, during the placing of the concrete in the trench:
• determining at least one first deviation parameter of the base of the first formwork element with respect to the vertical plane;
• and
• raising again the formwork device if the first deviation parameter is greater than a first given threshold and stopping the raising when the first deviation parameter is less than a second given threshold.
