FORMING PROCESS FOR ULTRA-LARGE-DIAMETER ANNULAR REINFORCING MESH COMPONENT

WIPO Patent Application WO/2022/262619

A1

Disclosed in the present invention is a forming process for an ultra-large-diameter annular reinforcing mesh component, the forming process comprising the following steps: S1, preparing a planar reinforcing mesh; S2, bending and forming the planar reinforcing mesh to form a semi-circular reinforcing mesh, and abutting and fixing two arc reinforcing meshes to form an annular mesh; and S3, abutting and fixing a plurality of annular meshes to form an annular component. In the present invention, planar reinforcing meshes are mechanically produced, then, the meshes are bent into arcs by using a special arc-bending apparatus, and finally, the meshes are joined into rings and provided with drag hook ribs in an insertion manner to finally form a component, such that the manpower input for steel bar binding can be reduced, the steel bar binding quality is improved, and the bridge tower construction efficiency is improved.
