Abstract

A thermally insulating construction element for use in a separating joint between load-absorbing parts of a building, in particular between an intermediate floor and a balcony slab, has an insulating body. The insulating body has mutually opposite longitudinal sides which extend in a longitudinal direction. The insulating body has compression shear bearings which are designed to take up horizontal forces and vertical forces. The compression shear bearings protrude through the insulating body in a transverse direction and project beyond the insulating body on both longitudinal sides of the insulating body. The compression shear bearings are spaced apart from one another with respect to the longitudinal direction of the insulating body. In order to allow good adaptation to forces to be taken up, the insulating body includes at least one compression bearing designed exclusively to take up horizontal forces and extends in the transverse direction of the insulating body.

Claims

1. A thermally insulating construction element for use in a separating joint between load-absorbing parts of a building, comprising:

an insulating body, wherein the insulating body has a longitudinal direction and mutually opposite longitudinal sides that extend in the longitudinal direction, wherein the insulating body has a transverse direction which extends transversely to the longitudinal sides and a height direction which extends perpendicularly to the longitudinal direction and perpendicularly to the transverse direction, wherein the insulating body has compression shear bearings which are designed to take up horizontal forces and vertical forces, wherein the compression shear bearings protrude through the insulating body in the transverse direction and project beyond the insulating body on both longitudinal sides of the insulating body, wherein the compression shear bearings are arranged spaced apart from one another with respect to the longitudinal direction, wherein the insulating body comprises at least one compression bearing which is designed exclusively to take up horizontal forces and arranged to extend in the transverse direction of the insulating body.

2. The construction element according to claim 1, wherein, on at least one longitudinal side of the insulating body, the compression bearing has a height measured in the height direction on the longitudinal side that is less than a height of the compression shear bearing measured in the height direction on the longitudinal side of the insulating body.

3. The construction element according to claim 2, wherein the compression bearing measured in the height direction on the at least one longitudinal side of the insulating body has a height that is less than 50% of a height of the compression shear bearing measured in the height direction on the longitudinal side of the insulating body.

4. The construction element according to claim 3, wherein the height of the compression bearing is less than 30% of the height of the compression shear bearing.

5. The construction element according to claim 1, wherein the compression shear bearings project beyond the longitudinal sides with an overhang of at least 1.0 cm.

6. The construction element according to claim 1, wherein the compression shear bearings protrude beyond each longitudinal side by way of at least one projection.

7. The construction element according to claim 6, wherein the compression shear bearings have an upper side and a lower side, and the at least one projection includes at least one projection arranged on the upper side and at least one projection arranged on the lower side.

8. The construction element according to claim 1, further comprising at least one tension bar that protrudes through the insulating body.

9. The construction element according to claim 1, further comprising at least one compression bar that protrudes through the insulating body.

10. The construction element according to claim 1, further comprising at least one shear bar that protrudes through the insulating body.

11. The construction element according to claim 1, wherein the insulating body has a lower side that extends between the longitudinal sides of the insulating body in the longitudinal direction.
