Abstract
A window is anchored more securely by removing the frame, drilling into the reveals of the window aperture between the faces of the wall, inserting into each drilling a rod encased in a loose fabric sleeve and injecting grout into the sleeve to expand it against the wall of the drilling, the grout permeating through the fabric and bonding to the wall. The ends of the rods are left exposed at the aperture and the frame is secured to them. Within the wall the rods may be looped and further drillings through the loops may be likewise filled by similar grouted reinforcements, linking several window anchorages together.
Claims16
A method of reinforcing the anchorage of a frame in an aperture in the wall of a building, the method comprising making a first drilling (14) into the reveals of the aperture from within the aperture, the drilling being between the inner and outer faces of the wall, inserting a reinforcing rod (10,17,22) enveloped by a loose fabric sleeve (11,18) into the first drilling, the proximal end of the rod being secured or securable to a frame within the aperture, and inserting grout to expand the sleeve against the wall of the associated first drilling to penetrate through the fabric and bond to the wall, characterised in that the rod (10,17) is curved back on itself at the distal end from the frame to form a loop, and the plane of the loop is substantially at right angles to the wall, and in that a second drilling is made into the wall between its two faces when the grout has set so that the drill bit passes through the loop, an extra reinforcing rod (26) enveloped by a loose fabric sleeve is inserted into the second drilling, and grout is injected to expand that sleeve against the wall of the second drilling to permeate through the fabric and bond to the wall.
