Article of manufacture for building structures made from precast concrete units and process for making structural system

摘要: An article of manufacture for building concrete structures from precast blocks and the process making structural system. The block comprises one or more annular tire wall stack units embedded in reinforced concrete. Prestressing and/or post-tensioning reinforcing techniques are used with assembled blocks. made by placing stacks a form that centralizes so can be placed around them while maintaining hollow core through stacks. Horizontal interlocking between uses bars tongue groove configuration, post-tension wire strand recess tubes formed mortared in-place during construction. Vertical tongue-and-groove interlock, shiplap splicing, bars. Post-tension strand, pipe, H-piles
