(57) A wall tie (10) for a timber frame cavity wall (19, 20) which is made as a generally
flat rectangular stainless steel strip having first and second stiffening formations
(12, 15) in the form of pressed ribs, separated by an unstiffened transverse junction
(16). The tie (10) can be bent about the junction (16), to bring abutment faces (17,
18) of the stiffening formations (12, 15) into abutment and limit the angle through
which the tie (10) is bent. In this condition, the tie is strong both in compression
and in tension, while remaining flexible enough to permit differential movement of
the inner and outer leaves (19, 20) of the wall. Chevron mortar keying formations
(27) are formed on the other end portion (23) of the tie. A method and cavity wall
construction are also described.
