Abstract

Abstract A structural assembly for producing interconnecting structures which includes a first element which, on each of two transversely extending sides lying opposite each other, is provided with a dovetail joint member and, on each of two longitudinally extending sides lying opposite each other, is provided with three fins which, when viewed from the tip or free end, have a convex portion provided on each side with a corresponding, connection recess so that the space between two adjacent fins is identical in form to the fin in order to permit a toothing to be formed. The structural assembly also includes a second element which is provided with a dovetail joint member on one longitudinally extending side and with three fins on the opposite side, as well as a connecting member which has, on each of two sides lying opposite each other, a dovetail joint member which corresponds to the dovetail joint members of the first element. Effective soundproofing walls or sloping walls can be produced simply in an interconnecting manner with such a structural assembly, and the individual elements can be produced economically.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 77 words
A structural assembly for producing interconnecting structures, comprising a first element which, on each of two transversely extending sides lying opposite to each other, is provided with a dovetail joint member used to connect said element to other elements, and on each of two longitudinally extending sides lying opposite each other, is provided with at least two fins having a convex portion provided on each side with a corresponding, connecting recess formed to correspond to the fins.
Claim 2
Dependent Claim 77 words
A structural assembly for producing interconnecting structures, comprising a first element which, on each of two transversely extending sides lying opposite to each other, is provided with a dovetail joint member used to connect said element to other elements, and on each of two longitudinally extending sides lying opposite each other, is provided with at least two fins having a convex portion provided on each side with a corresponding, connecting recess formed to correspond to the fins.
Claim 3
Dependent Claim 40 words
A structural assembly according to claim 1, wherein one side of the first element, not having either the dovetail joint members or the fins, is provided with a continuous groove, and an opposite side is provided with a corresponding rib.
Claim 4
Dependent Claim 23 words
A structural assembly according to claim 2, wherein the first element has an aperture at right angles to the groove and the rib.
