Patent ID: 11384534

Abstract:
A method is provided for securing external wall insulation (EWI) panels to the outer walls of a high rise building of large panel construction. The method involves first identifying the location of internal voids in outermost floor/ceiling panels of the building; and then creating continuous passages through the outer load-bearing wall panels of the building into the located internal voids, with each such passage forming a tie bar anchorage hole extending into the adjacent floor/ceiling panel. Down the length of each tie bar anchorage hole is inserted a tie bar that has, at an inner end portion, an anchorage, and at an outer end portion, an externally screw-threaded portion that projects from the outer load-bearing wall panel. A pattress plate is located at the outer end of each anchorage hole, with the externally screw-threaded outer end portion of each tie bar extending through the associated pattress plate.
