Abstract: A stationary supporting structure comprising one or more columns each assembled from a prefabricated concrete foundation element having a vertical steel tube linked to its upper surface to serve as a guide for annular prefabricated concrete elements which are successively threaded onto the tube. Initial skew due to an inclined ground at the erection site and tolerances in the length of any tie rods between the columns may be compensated for due to the fact that the prefabricated elements, although mating, may be displaced relatively to each other during erection of the structure, the mating surfaces being minor spherical surfaces, whereby the axis of each element can be adjusted relative to the axis of the next lower or upper element.

Abstract: The frame or skeleton of a building is erected by anchoring columns or studs in upright position and then fitting upon each upright a tubular casing prefabricated of concrete or other suitable cementitious material thereby sheathing the uprights. The space left in the casings is filled with hardening cementitious material for tying the uprights to their casings. Cross beams are joined to the uprights by providing at the upper end of each upright one or more lengthwise recesses in each of which is seated the end of one cross beam. Such joints support the cross beams safely yet permit limited adjustment of the cross beams and uprights relative to each other thereby imparting to the frame structure an inherent elasticity enabling the same to withstand high wind pressures and seismic shocks. Moreover, frame structures can be erected much faster and cheaper than heretofore possible by means of the simplified joints between upright and cross beams.
