Fastening assembly between a spiral metallic mesh mat and a peripheral framework in a form of continuous wire, which is highly resistant to a deformation laid out in helix and positioned on a total length between mat and the framework

摘要

The fastening assembly between a spiral metallic mesh (2) mat (1) and a peripheral framework (3) in a form of continuous wire (4), which is highly resistant to a deformation laid out in helix. The continuous wire is positioned on a total length between the spiral metallic mesh mat and the peripheral framework, and laid out around a rod in which the continuous wire passes through the entire external spiral mesh mat surrounds the framework. The helix formed with the continuous wire is deformed in a direction of shortening or lengthening step of helix. The fastening assembly between a spiral metallic mesh (2) mat (1) and a peripheral framework (3) in a form of continuous wire (4), which is highly resistant to a deformation laid out in helix. The continuous wire is positioned on a total length between the spiral metallic mesh mat and the peripheral framework, and laid out around a rod in which the continuous wire passes through the entire external spiral mesh mat surrounds the framework. The helix formed with the continuous wire is deformed in a direction of shortening or lengthening step of helix. The rod passes through the entire external spiral mesh mat. A projection of a helix coil on a plane perpendicular with a dimension of the helix is in circular, square or rectangular form. The continuous wire is present in a form of round or flat.
