From this you can calculate the height of the proposed awning. Code prohibits attaching any loadbearing member (both lateral and gravity) to any masonry veneer.

Think all those basketball rings attached to shed brick walls that have been pulled down and killed people and you get the idea. The gun-mixed or injection technique, used for solid or hollow masonry, delivers the pre-mixed adhesive through a specially designed gun that is inserted into the pre-drilled hole. Capsules are intended for solid, not hollow, masonry installation. Designers should factor in a shape coefficient to account for this. Would not closed roof change the pergola stability a bit due to wind lift up and require down pipe for drainage? For more information about how we use cookies. The type used depends on the region’s weather conditions and the awning fabricator’s preference.

Depending where you are located, different parts of the USA carry different things or may not carry some items at all.

Brick veneer provides the same attractive appearance as brick, but costs thousands of dollars less. Mounting only to the bricks could result in the bricks pulling out. The designer or engineer working on an awning must understand which, if any, of these forces will be at work on the awning once it is in place. Apart from the strength of the screw itself, the limiting factor of the wood must be examined when making this kind of connection (see “Lag screw formulas“).

Three common types are expansion anchors, where the bolt contains a wedge and is surrounded by a sleeve (hitting or screwing the bolt forces the wedge against the sleeve and the edges of the hole); hooked-end anchor bolts, which are set in wet concrete; and chemical anchors, which use epoxy to keep anchoring screws in place. Stallmeyer, McGraw-Hill, New York, 1996. Step 5 Counter flashing Chalk a straight line about 2 inches above the back of the base flashing. Because they determine the strength and number of anchorages needed, the loads imposed on the frame bear further discussion, as does the parent structure, since its compositional materials can determine the anchor type. You probably know that attaching wood to masonry isn't as easy as picking up a hammer and a nail, but it's also not an impossible task. Remember that an awning or canopy has a similar shape to a roof overhang, which the wind must go around.
