Abstract (en)
[origin: EP0641895A1] The invention relates to the use of wire-grating mats (2 to 4) in a three-dimensional support structure (1). The wire-grating mats (2 to 4) essentially consist of intersecting longitudinal and transverse wires (10 to 17) and has at opposite sides (18, 19) longitudinal-rod ends which follow a curve (21) and terminate with a length (22, 25) adjoining the curve (21, 24). The longitudinal-rod ends at one mat side are arranged in the mat plane while forming a hairpin (20) and at the opposite side (19) form a loop (23) which is bent at one side out of the mat plane in a curve, carries a transverse rod (28) in the curve (27) and is made to interlock by pushing the hairpin (20) with its straight length (22) adjoining the curve (21) of the hairpin (20) in between the loop head (24) and the transverse rod (28) arranged in the curve. The three-dimensional support structure (1) consists of several wire-grating mats (2 to 4, 35, 50) which are connected to one another and are arranged in intersecting directions for at least one direction of the support structure (1) in which several successive wire-grating mats (2, 3) successively serve to produce interlocking connections between them, the support of the hairpin (20) on the loops (23) being flexurally rigid in the direction of the outwardly acting pressure of the support structure. <IMAGE>
