Study model for a brick sculpture  

This detail is a modern repair solution of an original detail shown in Plate 36 of Terra Cotta Standard Construction published by the National Terra Cotta Society in 1927. This detail illustrates one method of repairing a terra cotta (TC) soffit, lintel, and facade units around a window opening. The TC veneer is supported by structural steel and brick masonry backing. TC facade units are held in place with stainless steel (SS) strap & pin anchors secured to the brick backing and engaged into the sidewalls of the TC units. Lintel units are hung on a continuous SS steel rod supported by threaded J-Hooks between the units. Each J-Hook is threaded at the top through one end of a tab anchor. The tabs are secured by threaded bolts through the flange of the steel channel. The original round anchor is not replaced. The steel is coated with a corrosion inhibitor. The TC units are typically left hollow. The TC soffit units are hung by two bent SS strap & pin anchors that engage through...

2019 Brick & CMU Cavity Wall, Composite model showing all seven conditions, in progress

  This detail illustrates a parapet condition including the roof termination into the masonry wall and the top of wall termination. The open web steel joists of the roof structure bear on the CMU wall via a steel bearing plate on a CMU bond beam. The roof system terminates with the roof counterflashing engaging with the masonry flashing, providing moisture protection for the wall and roof assemblies while allowing each assembly to be independent of the other. Insulation and air/moisture/vapor barrier are continuous across the masonry and roof systems providing defense against thermal and moisture transfer. A system of flashing and weeps at both sides of the wall underneath the coping prevents moisture from entering the wall through the coping joints. The masonry coping is supported by shims, and sealant & backer rod are used at the joints between coping stones to resist moisture. Coping stones are anchored to one another and to the wall, and all flashing penetrations are ...

This detail illustrates a masonry window head condition. The concrete masonry backing is treated with blocking at the perimeter of the opening which is wrapped with transition material, which in turn engages with the air/moisture/vapor barrier in the field of the wall providing continuous resistance to air and moisture. Continuous insulation offers excellent thermal control. An optional cavity drainage insert protects the weep vents at the bottom of the cavity from becoming obstructed. The detail incorporates a vertical brick expansion joint and a vertical control joint at the block backing. The loose steel lintel is protected with thru-wall flashing returning vertically at each end termination to form an end dam. The durable drip edge guards against moisture reentry and may be notched to avoid excessively thick laps. Firestop material may be used behind the lintel if required by code.
