03.020.0221 Wall system | Stone veneer wall, transitional, w/ brick backing & struct. steel framing



This wall system illustrates an example of a mid to high-rise transitional, or hybrid masonry wall. This type of construction was common between 1890-1940 and varies widely as it was a part of the transition from mass masonry load-bearing wall construction to steel skeleton frame construction. In this example the steel structural system supports floor loads and is encased in concrete and a 12” multi-wythe brick wall with stone veneer that encloses the building. The 4” stone veneer is tied into the masonry by metal z-strap anchors and at the top course by a metal cramp whereas the common brick is used as the backing and predominant wall infill. The anchors engage with the veneer stone by penetrating a kerf or channel that is cut into the top surface of each panel. The mass of masonry deflects bulk water penetration but is understood to take on a percentage of moisture that is free to evaporate slowly from the mortar joints on either side of the wall over time.

10.030.0633 Lintel rebuild | Terra cotta, extruded

This detail illustrates a modern rebuild strategy for replacing existing architectural terra cotta (TC) lintel, soffit, and accessory units around window openings. The existing TC is replaced with new extruded TC units, installed not filled, with weep holes at the underside of each overhanging unit; each secured with new stainless-steel anchorage. In restoring and rebuilding these types of historic wall systems, moisture mitigation is critical to their long-term preservation and performance. Moisture management measures in this detail include horizontal skyward-facing joint treatment of sealant or lead T-caps, and an integrated flashing system installed to protect existing structural steel. The flashing system includes a self-adhering flashing with ends dams secured by a termination bar with continuous sealant, a stainless-steel drip edge, and weeps in the vertical joints. Accessible existing structural steel is also protected by cleaning and coating with a corrosion-inhibiting co

10.030.0433 Sill and mullion rebuild | Terra cotta, extruded

This detail illustrates a modern rebuild strategy for replacing existing architectural terra cotta (TC) sill, mullion, and accessory units around window openings. The existing TC is replaced with new extruded TC units, installed not filled, with weep holes at the underside of each overhanging unit; each secured with new stainless-steel anchorage. In restoring and rebuilding these types of historic wall systems, moisture mitigation is critical to their long-term preservation and performance. Moisture management measures in this detail include horizontal skyward-facing joint treatment of sealant or lead T-caps, and an integrated flashing system beneath the sill. The flashing system includes a self-adhering flashing with ends dams secured by a termination bar with continuous sealant, a stainless-steel drip edge, and weeps in the vertical joints. The existing structural steel supports are also protected by cleaning and coating with a corrosion-inhibiting coating. These TC rebuild details

04.030.0202 Dimension stone wall, interior | Wire ties and molding plaster

     04.030.0202 Dimension stone wall, interior | Wire ties and molding plaster This detail shows 2 cm (3/4 in.) thick dimension stone anchored to an interior wall substrate with anchors of 8-gauge  (0.1285”) copper or stainless steel wire ties encapsulated by molding plaster at the perimeter of each stone panel. The wire is fitted into slightly oversized holes in edges of the stone panels, with wood plugs filling the space around the wire. The wire anchors are sized and spaced per empirical design and are fastened to the concrete masonry backing via holes cut into the block, also filled with plaster or rapid-curing cementitious material. Joints between the panels may be finished with compatible sealant and backer rod (not shown for clarity). This detail shall not be used for construction without the approval of a licensed design professional. The person using this detail shall be responsible for its complete design and proper application.
