<p>Method and means for fixing together building components, such as two skins of a cavity wall (10, 11). The components are "tied" together using a rod (13), inserted into holes (17, 18) drilled through the two components, on which are positioned a sleeve (20) such that it spans the cavity between the building components and three washers (22, 24, 26). The sleeve and washers are movable relative to each other and have ports (21, 23, 25, 27) which may be axially aligned to allow passage of a feeder pipe (28) for injecting binder (15) into the holes around the rod, or may be moved into disalignment to effect seals to prevent the binder from escaping from the holes.</p> |
