A frame support which can be used for inspection platforms, plant and equipment, prefabricated buildings and structures. The installation is carried out in three main stages, commencing with the fixing of a lightweight threaded base within a prepared hole. A load-bearing member is then attached to the base and adjusted by means of the thread and a threaded collar. Finally the threaded base, the threaded collar and a protrusion of the load-bearing member are substantially encased in concrete or a chemical compound to complete the installation. |
