Easiest, fastest and most accurate way to apply mortar & grout. Unlike other pointing guns, there is no small nozzle to block and no mechanism to break. The PointMaster's design keeps it simple, so you can use the tool more efficiently.
In architecture and engineering, a joist is one of the horizontal supporting members that run between foundations, walls, or beams to support a ceiling or floor. Typically, a joist has the cross section of a plank. Joists are often supported by beams laid out in repetitive patterns.
What youâre seeing here is a header built with a 2Ã6â³ bottom plate, 2Ã4â³ cripple studs, and a 2Ã4â³ top plate resting on the adjacent block walls. This header spans a 6â² opening and supports 4 floor joists (with 2 stories and a roof above it). The lowest point is at the middle and it sags down about 1/2â³.
