(57) A joist support for use in building and a building structure including such a support
are described. The joist support is a generally rectangular metal member (10) which
has a single oblique fold extending from one corner. The fold (11) divides the member
into flanges (15 and 16), the flange (15) abutting the side of a joist (17) in use
andthe other flange (16) affording a bearing portion (25) to rest on a supporting
structure (26). The bearing portion (25) is widest at the edge of the supporting structure
(26) which roughly coincides with the end (21) of the joist to avoid localised overloading
of the supporting structure. The fold (11) forms a rigid spine throughout the joist
support, to distribute the load of the joist across the width of the supporting structure
(26). Hence low density lightweight blocks can be used for the supporting structure
with reduced risk of crushing. A range of joist sizes can be accommodated using one
size of support because only one side face of the joist is located against the flange
(15), which also provides lateral restraint in combination with an upright (31) extending
into the masonry.
