06.EJ171.F Tile expansion joint | Floor movement joint, generic

Expansion joints in the field of tile floors are essential and required in order to accommodate building movements and to prohibit cracks in the substrate from telegraphing to the tile finish. This detail illustrates a generic movement joint in tile installed over a concrete floor with a cementitious bond coat. Bond breaker tape over the concrete prevents three-sided adhesion of the sealant. Joint width, location, and frequency of field expansion joints are as specified by the design professional. Sealant type shall be specified by design professional and shall be compatible with other components in the system. This detail is based on Tile Council of North America (TCNA) method EJ171F. Details that show different or modified concepts or methods can be of equal validity and should not be excluded from consideration. this detail shall not be used for construction without the approval an signature of a licensed design professional. The person using this detail shall be responsible for its complete design and proper application.

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
