What Types Of Movement Joints Are Required In A Concrete Masonry Wall?
Concrete masonry walls can be a strong and durable construction material, but they require a specific type of movement joint to ensure the wall remains stable.
Concrete masonry walls are typically constructed with a series of laminated, vertical concrete blocks and horizontal rebar. The rebar is used to form the wall’s framework, and the blocks are used to create the finished wall.
The most common means of securing floor joists to a concrete wall is to install a ledger board that matches the joist size.
The method used in typical 2 by 8-floor joist construction will insure proper support for the floor joists. The installation procedure can also be adapted to any floor joist size.
Other movement joints commonly used in concrete masonry walls include wire mesh, metal straps, and metal plates.
Wire mesh is often used to create a protection barrier between the wall and the floor, while metal straps and metal plates create stiffeners and provide stability to the wall.
Regardless of the type of movement joint used, it is important to use a certified contractor experienced in using movement joints in concrete masonry walls.
These joints can be tricky to install, and improper installation can lead to instability in the wall structure.
Can You Screw It Into The Concrete Wall?
Yes, you can, but you must take precautions. The concrete is very hard, and screws driven into the wall could snap off or be difficult to remove.
Masonry screws are an easy solution for fastening a wall to concrete. When you buy the screws, you’ll also need to get a special bit that makes a pilot hole match the fastener.
Drill at least 1/4 inch deeper into the concrete than the fastener’s embedment, and suck dust out of the hole with a shop vac.
If you’re looking for a fast and easy way to attach a wall to your concrete foundation, then Masonry screws are the solution. Not only are these screws fast and easy to use, but they’re also an environmentally-friendly option.
If you’re unfamiliar with Masonry screws, you should consider using them in your next project. These screws are a great option for attaching a wall to a concrete foundation, and they’re also a popular choice for attaching wood frames to a concrete wall.
Plus, Masonry screws are a great solution for fixing damaged walls. If you’ve accidentally damaged a wall, Masonry screws can be a great way to fix the damage. Drill a pilot hole in the concrete, and use the Masonry screws to attach the wall back together.
If you’re looking for a fast and easy way to attach a wall to your concrete foundation, then Masonry screws are the solution. Not only are these screws fast and easy to use, but they’re also an environmentally-friendly option.
How Do You Install A Dryer Vent In A Concrete Block Wall?
Here is how you can install A dryer vent in a concrete block wall;
Determine The Location Of Your Vent
Choose a location for your vent on your outer wall. Keep in mind that your duct can only run for a maximum of 25 feet, deducting 5 feet for every 90-degree turn and 2.5 feet for each 45-degree curve. Most ducts will have two twists, one at the exhaust port and another when the duct exits the wall at the vent, reducing the length of your duct to 15 feet.
Outside, the bottom of the vent must be at least 12-inches above the ground and at least that far away from any impediments, such as air conditioning units or decking.
Begin Drilling
Make a pilot hole through the concrete from the inside to the outside using your drill and a masonry drill bit.
Now, draw a 4.5-inch outline on the outer wall and begin drilling into the concrete with your drill’s hammer function. It will be difficult labor, so drill through nails with two hands and support your body against unexpected bumps. Allow the drill to cool down now and then to avoid overheating.
If your drill does not go through the wall, proceed only as far as the instrument will allow.
Use A Chisel And Hammer To Remove Concrete
If you haven’t reached the interior with your drill, remove the concrete with a hammer and chisel to the depth of the hole you’ve bored before returning to your drill. Repeat this method until you reach the top of the wall.
Mount Your Vent Hood
Insert the dryer vent hood pipe into the hole, with the vent cap towards the wall. Mount the cap with two screw holes on either side to the foundation with two half-inch concrete screws. Make sure you screw it down equally since one corner will not vent correctly if it is tighter than the others.
Use A Caulk Gun To Seal Your Vent Hood.
Caulk around the border of the vent with your caulk gun to seal the hood to the foundation. Caulk around the dryer duct on the interior with the plastic trim ring that came with the vent hood.
Measure And Fit Your Duct
Using tin snips, measure and cut your duct to the desired length, then fit it into an elbow at either end with metal foil tape.
Connect the dryer duct to the vent hood. Turn on your dryer and inspect the system inside and out to ensure that it is operational and that the vent flap is open.
