Gateway Park Center PERKINS+WILL <br /> 810495.000 <br /> 12/06/18 <br /> <br />REINFORCED MASONRY <br /> 04 22 13 - 8 <br />type joints, returns, and offsets. Avoid using less-than-half-size units, particularly at <br />corners, jambs, and, where possible, at other locations. <br />B. Bond Pattern: Unless otherwise indicated, lay masonry in one-half running bond with <br />vertical joint in each course centered on units in courses above and below, unless <br />otherwise indicated on Drawings. Interlock each course at corners. <br />C. Avoid using less-than-half-size units, particularly at corners, jambs, and, where <br />possible, at other locations. <br />D. Place clean units while the mortar is soft and plastic. Remove and relay in fresh <br />mortar any unit disturbed to the extent that initial bond is broken after initial <br />positioning. <br />E. Stopping and Resuming Work: Stop work by racking back units in each course from <br />those in course below; do not tooth. When resuming work, clean masonry surfaces <br />that are to receive mortar, remove loose masonry units and mortar, and wet brick if <br />required before laying fresh masonry. <br />F. Fill cores in hollow concrete masonry units with grout 24 inches under bearing plates, <br />beams, lintels, posts, and similar items, unless otherwise indicated. <br />G. Design, provide and install bracing that will assure stability of masonry during <br />construction. Include provisions to project against wind or other natural or <br />construction forces that might collapse or otherwise damage a partially or completely <br />built masonry wall in a partially completed structure. <br />3.5 MORTAR BEDDING AND JOINTING <br />A. Lay hollow masonry units as follows: <br />1. With face shells fully bedded in mortar and with head joints of depth equal to <br />bed joints. <br />2. With webs fully bedded in mortar in all courses of piers, columns, and pilasters. <br />3. With webs fully bedded in mortar in grouted masonry, including starting course <br />on footings. <br />4. With entire units, including areas under cells, fully bedded in mortar at starting <br />course on footings where cells are not grouted. <br />3.6 MASONRY JOINT REINFORCEMENT <br />A. General: Provide continuous masonry joint reinforcement as indicated. Install entire <br />length of longitudinal side rods in mortar with a minimum cover of 5/8 inch. Lap <br />reinforcement a minimum of 6 inches. <br />1. Space reinforcement not more than 16 inches o.c. <br />2. Space reinforcement not more than 8 inches (203 mm) o.c. in foundation walls <br />and parapet walls.
