  • Patent number: 11686115
    Abstract: A wall brace system for providing an apparatus for supporting a wall in a building structure, which has been moved inward by pressure from the earth outside in order to return the wall to a desired position. The wall brace system has a structural member, a retainer, a mounting assembly, a load member, a jack, and/or a locking member. A jack and/or locking member are operatively coupled between the structural member and the mounting assembly. The jack functions to exert a force against the structural member, directly or through the load member, in order to force the structural member toward the wall for shifting the wall (e.g., outwardly). The locking member functions to lock the structural member in place with respect to the mounting assembly after the jack positions the structural member. Thereafter, the jack is removed from the mounting assembly.

  • Patent number: 9016025
    Abstract: A constructing method for a concrete cylinder of a construction steel bar of a high-rise steel structure adopts a constructing method of supporting inside and climbing outside. The outside of the cylinder adopts hydraulic mutual-climbing adhesive lifting scaffold creeping formwork system (100), and also has an outside wallboard mechanical formwork erection function and an outer frame protection function. For the inside of the cylinder, except that an appropriate structure is left for later processing according to a schedule requirement, beam walls all adopt a steel cylinder support to perform formwork erection, so as to greatly reduce the workload of repeatedly mounting/dismantling the scaffold and the formwork at a high place. The scaffold itself carries the formwork erection system, so formwork erection and formwork removal can be mechanized, thereby reducing the risk of formwork erection and formwork removal at a high place.

    Abstract: A method and structure for assembling field erected cooling. A first cell or cell portion is assembled at the opposite end of the cooling basin from its final location and used as a scaffold from which the rest of the structure is assembled. This first “assembly” section is fitted with temporary walkways, safety railings and enclosed ladders and workers assemble each new section of the cooling tower frame from the scaffold affixed to the first section. After assembly of each section or bay of the cooling tower frame is completed, the assembly section is advanced away from the newly constructed section to make room for the assembly of a new section. To advance the assembly section, movable lifts are positioned under the bottom transverse beams of the section.
