Copyright Goodheart-Willcox Co., Inc. 240 Section 4 Techniques 12.3.4 Laying an 8″, Two Wythe Intersecting Brick Wall Intersecting brick walls are often necessary in the con- struction of brick structures. The walls are laid out so the courses are tied together to form an integrated unit. Individual units are placed so they interlock the wall segments together. Reinforcement ties (Z ties) are gen- erally used. The following procedure can be used to construct an 8″, two wythe intersecting brick wall in standard run- ning bond with joints broken so they do not line up ver- tically. Refer to the numbered bricks in Figure 12-48. P R O C E D U R E Laying an 8″, Two Wythe Intersecting Brick Wall 1. Locate the face of the walls on the floor and snap a chalk line to preserve the location. 2. Lay out the first course using no mortar (dry bond) to maintain proper spacing and identify any difficulties or problems. 3. Spread the mortar bed and lay out the face wythe beginning with brick #1 through brick #2 in Figure 12-48. Level, align, and plumb the course of brick. 4. Lay the backing wythe beginning with brick #3 and continuing with brick #4. Do not forget to butter the back side of each brick where the backing wythe sits against the face course. This joint (collar joint) should be completely filled. Level, align, and plumb the course and check the wall thickness. 5. Lay the intersecting wall brick beginning with brick #5 and then brick #6, running each course to the outside wall. Level, align, and plumb each course and check the wall thickness. This completes the first course plan. Second course First course Pictorial view 1 3 2 4 6 5 Goodheart-Willcox Publisher Figure 12-48. The procedure for laying an 8″, two-wythe intersecting brick wall.
