  • Multi-story buildings from prefabricated concrete components
    Patent number: 8341902
    Abstract: Multi-story buildings assembled from pre-cast concrete components produced in a component factory to form earthquake-resistant buildings with lower cost and faster construction time. The multi-story building structure comprising a plurality of piles and pile caps; prefabricated concrete column components; prefabricated concrete beam components; prefabricated concrete floor components; prefabricated concrete stairs components and prefabricated concrete wall components. Each pile cap unites at least two piles to one column; each column component has a groove on each side of the column component for placement of the corresponding sides of prefabricated wall components; and each beam component comprises grooves on the bottom and top sides of the beam for placement of wall components; and openings are located in the body of the beam. Floor components, stairs components, and wall components are made of concrete that are pre-cast with a predetermined shape, size and strength as described.
