Abstract
A preassembled unitized masonry reinforcement for cavity walls or composite walls utilizes a ladder or truss-type block mesh and suitable numbers of standard length corrugated metal wall ties pivotally and slidably connected in permanently assembled relationship to block mesh members, whereby the wall ties may be freely adjusted by pivotal and/or sliding movements to the most advantageous positions of use and similarly may be positioned for shipment entirely or nearly within the boundaries of the block mesh reinforcement. Various wall tie configurations by bending of ties can be achieved to compensate for misalignment of mortar joints in composite or cavity walls. The hinge or pivot joints between ties and reinforcing mesh members are mortar locked within bed joints of the wall for added security.
Claims13
An adjustable prefabricated masonry reinforcing unit comprising a block mesh reinforcement body portion of the truss type including parallel longitudinal rod members rigidly interconnected in a substantially common plane by cross-connecting rod members, said parallel longitudinal rod members defining the side boundaries of the width of said body portion, said body portion being of a width adapted for placement wholly within a bed joint of one wythe in a wall structure, and a plurality of elongated corrugated strip ties pivotally and slidably connected through closed loops in permanently assembled relationship with at least one of said rod members of said body portion with said pivotal and slidable closed loop connections positioned on said at least one of said rod members for placement bodily within the bed joint of said one wythe, said ties being independently adjustable lengthwise of the body portion and also being independently adjustable laterally of the body portion to vary their distances of projection outwardly of one of said longitudinal rod members defining the longitudinal side boundaries of the body portion, said ties following their adjustments on the body portion being engageable in bed joints of a second wythe in a wall structure, and said ties being independently shiftable through said closed loop connections to protected shipping positions on the body portion where the ties are located substantially within the side boundaries of the body portion formed by said parallel longitudinal rod members and substantially in said common plane of the body portion forming a compact, integral shipping unit.
