The present invention relates to a welded chain lining net intended for securing walls and/or ceilings of defined spaces, especially mine galleries, against falling pieces. The welded chain lining net according to the present invention consists of plurality net fields comprised of elongate rods (1) of diameter (D) and transverse rods (5) attached thereto wherein said elongated rods (1) are terminated from one side by pendent ends (K) with U-shaped suspension hooks (2). On the other side, a pendent transverse rod with diameter Di1 is attached from below to the ends of arbitrary shaped elongated rods (1) while a supporting transverse rod (4) is attached thereto from above. Pendent ends (K) of the elongated rods (1) with suspension hooks (2) are bent such that the distance (H) of the horizontal ayes of the suspension hooks (2) bend from the plane (A) of the lining net are given by the relationship H is greater than (D+Di1)/2. |
