LATH WITH RIBS

摘要

PROBLEM TO BE SOLVED: To provide a lath with ribs, which prevents a lath portion enclosed by mutually adjacent first ribs and mutually adjacent second ribs, from warping toward a substrate when the substrate having the lath with the ribs fixed thereto is coated with mortar or the like, and can be located at a necessary location in the mortar or the like as a whole, to thereby positively exert effective reinforcement.;SOLUTION: According to the arrangement of the lath with the ribs, the first ribs 10 are arranged on a rear side of the flat lath 12 at regular transverse intervals, and the second ribs 14 are arranged on a front side of the flat lath 12 at regular longitudinal intervals. Then an intersection between the first rib 10 and the second rib 14 is welded to form an intersection joint portion C which is then formed into a rib projection 16 by press working in a manner being protruded from a predetermined plane P of the intersection joint portion toward the rear side by a predetermined height. Then a center portion of the square lath portion enclosed by the mutually adjacent first ribs 10 and the second ribs 14 out of the overall flat lath 12 is protruded toward the rear side by a predetermined height to form a lath projection 12b.;COPYRIGHT: (C)2008,JPO&INPIT
