Abstract

Apparatus for erecting a domed structure includes a support base and a guide member extending vertically from the support base. A lifting tower movably engages the guide member. The lifting tower is formed of sequentially added sections telescopingly mounted on the guide member. A plurality of push-up devices are mounted adjacent to the base. A first one of the push-up devices engages a first added section of the lifting tower. A second one of the push-up devices engages a second added section of the lifting tower. The first added section of the lifting tower is offset from the second added section of the lifting tower so that the lifting tower is vertically extended in a stepped sequence relative to the guide member. A dome formed of structural components extends radially outwardly from the lifting tower. A plurality of suspension members are attached to the lifting tower and extend radially outwardly into attachment with the dome, for elevating the dome in response to alternately actuating the first and second push-up devices.
