Abstract
Abstract Described is a fastening element for sheathing and thermal insulation components (1) of hard foam material, in particular for the cladding concrete method of construction, which has a plate (6) which can be fixed to the hard foam material component (1) and is provided with extending fastening means (11). The plate (6) is desirably made from concrete and has a groove-and-tongue arrangement (7, 8) which co-operate with corresponding grooves (3) and tongues (4) on the component (1) so that the fastening elements (2) is fixed to the component (1) in such a manner as to be adjustable in respect of height.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
113 words
A fastening element for use in forming concrete wall structure within sheathing components wherein said sheathing components and the fastening elements comprise mutually interlocking members for fixedly joining the fastening elements to said components, said fastening element being formed of concrete and comprising a plate-like member having on one side thereof a surface configuration adapted to form an interlocking contact with a corresponding facing surface configuration on a sheathing component, said fastening element having a shank on a second side thereof, fastening means fixed to said shank and adapted to interconnect one sheathing component to a second sheathing component for fixing said components relative to each other to receive concrete between said components.
Claim 2
Dependent Claim
