The cast-in-place concrete ku it is, additional strength reinforced Inlaying necessary hollow formation tool to top

摘要

(57) Abstract Constitution It consists of the cylinder (2). The cylinder (2) in the bottom, it hardens,It is the hardening concrete break component which makes the concrete breakIn order (7), to project to inner split, it locks. Cylinder (2) inside,Cylinder pulling up component (4), top as many as cylinder (2) compared to in upper part protrudingIt locks when it is put out. Cylinder (2) in peripheral face, elastic sheet(3) is wound. Advantages The cast-in-place concrete ku it is, on top the additional strength reinforcing rodIt is possible to form the Inlaying necessary hollow simply. Furthermore, formaFrom length and formation tool top of forming tool hardening concrete break sectionBy alteration the distance to the material, additional strength of various depthsForm the reinforced Inlaying necessary hollow, simply according to desire sizeIs possible.
