<p>A building cladding construction comprises a plurality of spaced apart elongate support members (10), a plurality of elongate structural members (13) each having a longitudinal axis (A1), supported by the support members (10) in side-by-side parallel, spaced relation and extending transversely of the support members (10) to span the spaces between adjacent support members (10), and at least one restraint tie (14,15) associated therewith, and extending between each pair of adjacent structural members (13), the or each tie (14,15) comprising an elongated body having a longitudinal axis (A2), a web (17), and an outwardly extending limb (18) at each longitudinal edge of the web (17), each end part (19) of the body having first and second pairs of abutments (21,22), the first pair (21) of abutments being spaced apart longitudinally of said axis (A2) of the restraint tie (14,15) from, and opposed to, the second pair (23) of abutments, the abutments (21,22) comprising the edges of slots (20) formed in said limbs (18,18 min ) and/or the web (17), so that the abutments (21,22) of each pair are spaced apart in a direction transverse to the longitudinal axis (A1) of the structural members (13), the structural members (13) of each pair having at least one aperture (16) therein, characterised in that the or each aperture (16) of such configuration that one of said end parts (19) of the restraint tie (14,15) can be received within the aperture (16) with the web (17) of the restraint tie extending transversely of the longitudinal axis (A1) of the structural member (13), said first and second pairs of abutments (21,22) engaging opposite faces of a wall (27) of the structural member (13) around said aperture (16) with at least one abutment of each pair (21,22) being spaced from the longitudinal axes (A1) of the structural members (13) in a direction towards the support members (10) so that each of the structural members (13) are restrained against rotation about an axis coincident with or parallel to the longitudinal axis (A1) thereof, and held in parallel relation.</p> |
