Abstract

A structural element for thermal insulation between two building parts, particularly between a building (B) and a projecting external part (A), including an insulating body (2) to be arranged between the two building parts and including reinforcement elements in the form of at least tensile reinforcement elements (3), which in the installed state of the structural element (1) extend through it essentially horizontally and perpendicularly in reference to the essentially horizontal longitudinal extension of the insulating body, and respectively project in the horizontal direction beyond the insulating body and here can be connected to at least one (B) of the two building parts preferably made from concrete, with the tensile reinforcement elements (3) comprising an anchoring element (6, 16, 26, 36) in an area of at least one building part (B) surrounding its radial exterior, with the anchoring element at least including an anchoring bushing (6a, 16a, 26a, 36a) made from a concrete material and a profiling (6b, 16b, 26b, 36b), provided at the radial exterior of the anchoring bushing and projecting outwardly, particularly in the radial direction.

Claims

1. A structural element for thermal insulation between two building parts, the structural element comprising an insulating body (2) that is arrangeable between the two building parts and reinforcement elements including at least tensile reinforcement elements (3), which in an installed state of the structural element (1) extend through the insulating body (2), horizontally and perpendicularly to a horizontal longitudinal extension of the insulating body, and respectively project in a horizontal direction in reference to the insulating body and are connectable to at least one of the two building parts, with the tensile reinforcement elements (3) comprising an anchoring element (6, 16, 26, 36) surrounding a radial exterior thereof configured to be in proximity to the at least one of the two building parts, the anchoring element (6, 16, 26, 36) comprises at least one anchoring bushing (6a, 16a, 26a, 36a) composed of a concrete material and the anchoring element (6, 16, 26, 36) includes a profiling (6b, 16b, 26b, 36b) located on an outside thereof that is positioned on a radial exterior of the anchoring bushing, and configured to transfer a load between the tensile reinforcement element and one of the two building parts.

2. The structural element for thermal insulation according to claim 1, wherein the profiling (16b, 36b) comprises ribs that extend at least over a portion of a perimeter of the anchoring bushing (16a, 36a).

3. The structural element for thermal insulation according to claim 1, wherein the profiling (6b, 16b, 26b, 36b) extends only over an axial portion of the anchoring bushing (6a, 16a, 26a, 36a).

4. The structural element for thermal insulation according to claim 1, wherein the anchoring bushing (6a, 16a, 26a, 36a) is formed with a smooth wall on a radial outer surface at an edge area near the joint.

5. The structural element for thermal insulation according to claim 1, wherein the anchoring bushing (6a, 16a, 26a) has a cylindrical casing area.
