Fully integrated precast concrete construction including provisions for insulation and all services-HVAC, plumbing, lighting etc.

Abstract

The integrated precast building system provides for all construction elements. The walls, floor, and roof form an integrated structure of module length (FIG. 3 ). Passages for HVAC, electrical wiring and piping are provided. Inserts for decorative panels and lighting are easily installed and removed. The sloped roof requires no covering. A flat roof can be made with the floor panel but the roof would not be as waterproof as the recommended sloped roof. The system is applicable to homes thru large commercial buildings. The building goes together faster and is completed quicker because all details of the structure are integrated. Life cycle costs are minimized because the structural elements need no painting and do not deteriorate. The basic structure is fireproof. Modifications are easy. Removing the inserts, installing the changes and replacing the inserts facilitate modifications. The buildings can withstand earthquake 4 requirements when post tensioned.

1 . The building system is fullly integrated. Walls, floors, and roof are designed to join each other and provide passages for heating, lighting, air conditioning, and plumbing. Such passages can be used after the building is finished. Modifications can use these passages for economical changes without disturbing the existing building.  
   
   
       2 . All structural elements of the building are fireproof  
   
   
       3 . The building system can produce multiple types of buildings from homes to high rise buildings.
