Fiber cluster for use as e.g. double wall anchor, in concrete building, is anchored in linear or point form, where fibers run uni-directionally in section of cluster, while fibers run multi-directionally at both ends of cluster

摘要

The fiber cluster is anchored in a linear or point form, where the fibers include glass fibers, aramid fibers, steel fibers, polypropylene fibers or alkali resistant fibers. The fibers are twisted. The fibers run uni-directionally in a section of the cluster, while the fibers run multi-directionally at both ends of the cluster. The fiber cluster is fastened to a metallic component.
