Device for thermally insulating, force-transmitting retrofitting of a second load-bearing construction element to a first load-bearing construction element and structure with such a device

A device for thermally insulating, force-transmitting retrofitting of a second load-bearing construction element to a first load-bearing construction element, the device comprising:

• an insulation body configured to be arranged in a construction joint between the first load-bearing construction element and the second load-bearing construction element, wherein the insulation body comprises a shape-stable casing filled with an insulation material, wherein the casing comprises a first longitudinal side configured to be arranged at the first load-bearing construction element and an oppositely positioned second longitudinal side, wherein the casing comprises a length direction, a transverse direction extending perpendicularly to the length direction and extending from the first longitudinal side to the second longitudinal side, and an upright direction extending perpendicularly to the length direction and perpendicularly to the transverse direction;
• at least one compression element configured to transmit compressive forces between the first load-bearing construction element and the second load-bearing construction element and extending at least from the first longitudinal side of the casing to the second longitudinal side of the casing;
• first tension rods projecting into the casing at the first longitudinal side of the casing;
• second tension rods projecting into the casing at the second longitudinal side of the casing;
• a connection arrangement arranged completely enclosed by the casing and configured to force-transmittingly connect the second tension rods to the first tension rods;
• wherein the connection arrangement comprises at least one screw connection, wherein the screw connection comprises at least one threaded section arranged inside the casing.

A structure comprising:

• a first load-bearing construction element comprised of concrete and a second load-bearing construction element comprised of concrete;
• a device for thermally insulating, force-transmitting retrofitting of the second load-bearing construction element to the first load-bearing construction element, the device comprising:
• an insulation body configured to be arranged in a construction joint between the first load-bearing construction element and the second load-bearing construction element, wherein the insulation body comprises a shape-stable casing filled with an insulation material, wherein the casing comprises a first longitudinal side configured to be arranged at the first load-bearing construction element and an oppositely positioned second longitudinal side, wherein the casing comprises a length direction, a transverse direction extending perpendicularly to the length direction and extending from the first longitudinal side to the second longitudinal side, and an upright direction extending perpendicularly to the length direction and perpendicularly to the transverse direction;
• at least one compression element configured to transmit compressive forces between the first load-bearing construction element and the second load-bearing construction element and extending at least from the first longitudinal side of the casing to the second longitudinal side of the casing;
• first tension rods projecting into the casing at the first longitudinal side of the casing, wherein the first tension rods are embedded in the concrete of the first load-bearing construction element and thus force-transmittingly connected to the first load-bearing construction element;
• second tension rods projecting into the casing at the second longitudinal side of the casing, wherein the second tension rods are embedded in the concrete of the second load-bearing construction element and thus force-transmittingly connected to the second load-bearing construction element;
• a connection arrangement arranged completely enclosed by the casing and configured to force-transmittingly connect the second tension rods to the first tension rods.
