Abstract
Abstract A multi-story building with concrete floor slabs and supporting columns is formed in a roof down fashion and erected in a progressive lifting process from the foundation. Auxiliary columns in the form of sectional steel casings hold fresh concrete to form the columns, support the building while the concrete columns harden and provide means for attachment to lifting devices that are supported on bearing platforms at the foundation. The load of the permanent concrete structure is transferred to the auxiliary columns through interlocking surfaces between the casings and the concrete columns. The auxiliary columns are pushed up by the lifting devices, that act in a climbing fashion, until the concrete therein hardens to a strength to support the weight of the upper part of the building. The sections of the casings are then peeled off and rotated to positions below for reuse so that the bottom part of the building is always supported by the auxiliary columns acting as an interim support structure. When the building has reached the planned height, the lowermost concrete columns are cast solid with the foundation and the auxiliary equipment is removed for reuse in other buildings.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
277 words
Apparatus for the formation of a multi-story concrete building having superposed floor slabs spacedly supported by load bearing concrete columns comprising: a. a horizontal platform disposed at ground level and having vertical openings; b. foundation means underlying each of the openings in the platform; c. supporting means mounted on the foundation means; d. lifting means operatively mounted on the supporting means; e. auxiliary columns disposed in vertical positions overlying the foundation means and underlying the openings in the platform and into which concrete flows as a floor slab is being formed on the platform so as to form the concrete columns; f. means connecting the lifting means to the auxiliary columns with saiD lifting means being operative so that after a predetermined setting time the poured floor slab and the auxiliary columns with the contained concrete columns are elevated to a height with the lower ends of the auxiliary columns being adjacent the platform; g. means attaching the lifted auxiliary columns to the supporting means so that they are locked in such elevated positions for the insertion thereunder of further auxiliary columns for the subsequent formation of further concrete columns during the formation of a succeeding lower floor slab on the platform; h. means interconnecting the lower ends of the raised auxiliary columns with the upper ends of the underlying auxiliary columns with a space approximately equal to the thickness of a floor slab being provided therebetween; and i. interlocking facial contact means between the auxiliary columns and the concrete columns formed therein so that lifting pressure applied directly to the auxiliary columns is indirectly applied to the concrete columns and therethrough to the supported floor slab.
