This assembly details the base anchorage for an elevator buffer stand and a holeless hydraulic jack mounted to a concrete pit floor. The buffer stand uses a three-quarter-inch thick by eight-inch by eighteen-inch long anchor plate secured with three five-eighths-inch diameter Hilti KB-TZ2 expansion anchors requiring a minimum three-and-a-quarter-inch nominal embedment. A structural angle L4x4x3/8 eleven inches long is anchored with two five-eighths-inch diameter Hilti KB-TZ2 expansion anchors to support the rail. A note specifies a maximum two percent pit floor slope at the angle, requiring full bearing by grinding the concrete flat or providing grout if necessary.
