Abstract
Steel caissons are assembled from steel components comprising plates or channel sections from which project a plurality of connecting means such as pins or bolts and on which are mounted reinforcing bars. The assembled caisson is a hollow steel beam of any desired cross-sectional shape and containing the reinforcements. Concrete is poured in situ into the hollow beam, which may also contain a sand-filled shaft.
Claims6
A prefabricated hollow metal caisson for a building structure and to be placed below ground level and filled with concrete, comprising:
- at least two prefabricated longitudinal metal wall components each being secured to adjacent components along the longitudinal outer side edges thereof to form a prefabricated hollow caisson, each wall component being provided with a plurality of longitudinally spaced projecting connecting means arranged along each wall component and extending inwardly and perpendicularly from the inner surfaces of the hollow caisson, said projecting connecting means terminating short of the central area of the caisson for providing an open area for admission of concrete into the caisson, and a plurality of longitudinal reinforceing members secured to the inner ends of said projecting connecting means and spaced from the central open area of said caisson.
