A method for erecting absorber towers using trestle means (26) with jack means (32) to assemble a course and then lift it while constructing the next course below it. The first course is lowered on the just assembled course and welded thereto. These steps are repeated to form the outer wall (34) of the absorber tower (10). A clearance (48) is provided between the elevated course and the course to be assembled for installing the internal components of the tower. Advantageously, the method of the present invention allows for the construction of an absorber tower on site in retrofit applications where space may be restricted and access limited.
Two methods of constructing either a metal or wooden framed multi-story building and corresponding apparatus utilized in the construction. Building includes erecting roof frame beams and subsequent floor levels. For a metal framed building, motorized lifting devices are positioned on specific metal bars. Each metal floor frame has corresponding metal lifting bars. Metal post beams are supported by metal assembly brackets of several lengths, including a spacer block during the repositioning of the motorized lifting devices for the next floor level. The metal corner post beams and the motorized lifting device can further be supported during the lifting procedure by a collar and bracket system. The horizontal level of each floor is controlled by a central control system including lasers, laser sensors and a computer. A second embodiment is directed to the building of wood houses to utilize cantilevered metal lifting bar assemblies supported by lifting devices. The lifting bar assemblies have adjustable framing spaces on top for forming one to three joists in a space. The corner and intermediate outside posts can be formed to have a predetermined set of holes for fastening a glass facade for the building. The construction can be aided by the use of a combination building support and work area assembly placed in the ground on the outside of the building.
