Abstract
Abstract A wall element consists of a ground wall with a shield that is placed on it perpendicularly and side walls extending laterally from the shield to the rear. In high walls that can be 7 meters or higher, in order to withstand the high static load that exerts force on the ground wall the side walls are formed in such a manner that their upper front surfaces are situated above the groove-shaped recesses located in the bottom surface of the ground wall, so that the load is transferred only via the side walls and prevents the side walls from collapsing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
175 words
A concrete, trough-shaped, wall element for the dry construction of walls comprising: a front shield, two side walls extending to the rear, and a ground wall located beneath the front shield and two side walls, wherein the ground wall on its underside includes at least one recess arranged parallel to the side walls, wherein each side wall is narrower on its free upper front surface than at its base part, and wherein a slot having parallel walls is provided in each side wall extending through the entire width of each side wall, and wherein an insertion plate is inserted in said slot to subdivide the trough-shaped, wall element into a front pan and rear trough, the insertion plate having a width for insertion into said slots, a breadth exceeding a total breadth of the element and extending beyond outer surfaces of each side wall, a height substantially equal to a height of the element, and a bottom recess for enabling the insertion plate to engage lower portions of the outer surfaces of each side wall.
Claim 2
Dependent Claim
175 words
A concrete, trough-shaped, wall element for the dry construction of walls comprising: a front shield, two side walls extending to the rear, and a ground wall located beneath the front shield and two side walls, wherein the ground wall on its underside includes at least one recess arranged parallel to the side walls, wherein each side wall is narrower on its free upper front surface than at its base part, and wherein a slot having parallel walls is provided in each side wall extending through the entire width of each side wall, and wherein an insertion plate is inserted in said slot to subdivide the trough-shaped, wall element into a front pan and rear trough, the insertion plate having a width for insertion into said slots, a breadth exceeding a total breadth of the element and extending beyond outer surfaces of each side wall, a height substantially equal to a height of the element, and a bottom recess for enabling the insertion plate to engage lower portions of the outer surfaces of each side wall.
