Typically, concrete masonry units have nominal face dimensions of 8 in. Bending and soldering a saddle is complicated, but sheet metal shops need only two pieces of information from you to bend up a saddle: the width of the chimney and the slope of the roof (see How to Find Your Roof Slope,). These cracks form due to the uneven stress distribution in the walls. Cabot plucks some petals. 0000046569 00000 n Standard Specification for Loadbearing Concrete Masonry Units, ASTM C90 (ref. 0000041396 00000 n This area carries smaller stress. 5).

It must be placed so that longitudinal wires are embedded in mortar with a minimum cover of: Building Code Requirements for Masonry Structures includes prescriptive requirements for joint reinforcement. Back cap flashing. Chimneys are notorious for leaking, and the culprit is almost always the sheet metal flashings. (203 x 203 x 406 mm) concrete masonry unit. ASTM C90 also defines the difference between hollow and solid concrete masonry units. An expansion joint, or movement joint, is an assembly designed to hold parts together while safely absorbing temperature-induced expansion and contraction of building materials, and vibration, or to allow movement due to ground settlement or seismic activity. Intersecting walls, when depending on each other for lateral support, can be anchored by several prescriptive methods including the use of joint reinforcement spaced no more than 8 in. For maximum safety, especially if the roof is steep or high, buy a personal fall arrest system consisting of a safety harness, lanyard, rope-grab, rope and roof anchor. The next step is to mark and cut the grooves in the chimney's mortar joints to accept the cap flashing. Adjustable ties, tabs, third wires and seismic clips are also available in combination with joint reinforcement for multiwythe and veneer walls. Dj plus de 15 millions d'utilisateurs ! |+W:Tr7X .
