Abstract: A mounting arrangement 10e is provided for a cleat 30a or other body for receiving the ends of elongate reinforcements (e.g. rebars 40a, 40b) in a bond beam in a masonry panel 66. The mounting arrangement 10e secures the cleat to a further reinforcement (e.g. rebar 38a) and surrounding cementitious material in a hollow masonry block encased, reinforced cementitious material column 64. An expansion joint 70 may be provided between the column 64 and the panel 66. Connections between the head and foot of the column and pre-existing load bearing structures are also described.
Abstract: A masonry infill in a load bearing structure (18), comprises courses of hollow masonry units (1) arranged to define a cavity (3) extending therethrough filled with reinforced cementitious material e.g. reinforced concrete. A lower end of the concrete reinforcement (2) is secured to a load bearing support (16, FIG. 3). A body (6) is secured to the load bearing structure and receives an upper end of the concrete reinforcement so as to permit longitudinal sliding movement of the reinforcement upper end in the body, whilst constraining movement of the concrete reinforcement in a direction transversely of the infill The lower end of the reinforcement (2) may be built into the support, or slidably received in a further body (5, FIG. 3). Alternatively one or both ends of the reinforcement (2) may terminate in a bond beam. Brackets (9, 9a) may be embedded in the concrete in the cavity (3) to transfer shear forces between the adjacent blockwork and the concrete.
Abstract: A method of constructing a masonry infill in a load bearing structure comprises the steps of: laying one or more courses of masonry (7) in the infill space; partitioning off a casting space having as its base the then uppermost course of masonry (22); the casting space extending from one side of the infill space to the other; positioning reinforcing material (14) in the casting space; securing an end of the reinforcing material to the load bearing structure; filling the casting space with concrete (20), and laying one or more further courses of masonry on top of the filled casting space. The reinforced concrete forms a bond beam which strengthens the masonry. The reinforcing material may be rebar, secured to a load-bearing frame of the building by a cleat (16) having pockets (12) for reception of the rebar ends. Optionally the reinforcement may be tensioned, to pre-stress the bond beam.
