Lintels Brick Veneer Lintel
This leaves me with the need to update my lintel schedule on the job. Masonry veneers can also be attached to poured concrete walls. The slab edge is then supported by a spandrel beam. Masonry veneer shall not support any vertical load other than the dead load of the veneer above. Long leg of the angle shall be placed in a vertical position. Depth of reinforced lintels shall be not less than 8 inches and all cells of hollow masonry lintels shall be grouted solid. The below table applies to this method.

Loose Lintel for Brick Veneer – Masonry Veneer Lintels
There are a number that appear this way after going through building exterior shots.
Marcel it must be your first thought as far as lintel extension goes but wanted to hear it from someone else.
Support the load and bond the brick plains.
Foam doweling and expansive caulk are used to adsorb the expansions, contractions.
Could be a iron beam retro fit just for the baloney section.
The tributary length of the veneer can be assumed equal to the span of the veneer used to determine the anchor spacing, and will include the additional weight of the shelf angle.
Connection detailing, height of veneer, length of angle legs and angle thickness will all affect how much of the angle is effectively resisting these reactions.
This 4 x (the nominal veneer thickness) product was also used to determine the effective length of masonry wall under concentrated loads in older versions of the masonry standard, and thus has been used to describe effective width of steel and masonry systems in the past.
To determine the thickness of angle needed, the veneer weight is often assumed to be applied at the end of the horizontal angle leg.
The vertical leg of the angle would also have to be evaluated and sized. For this case, the tension stress on the same effective length of the angle would be less than 500 psi (less than 2% of the capacity) and can safely be ignored.
Design of Steel Lintels in Masonry Walls
Note that this analysis ignores any shear lag effects.
As can be seen from the analysis presented above, a reasonable angle thickness and support spacing can be determined. Even if the brick does crack, however, there will likely be at most two sections of brick acting over a given span. Can it also be placed with horizontal leg at top? It seems that the code is lacking at this time. Briefly, like clay brick terra cotta is a fired clay product, so just like brick it expands with moisture. You can see the impact of this growth at the outside corners of the buildings, where the façade has grown enough to create vertical cracks and to separate from the façade in the perpendicular direction.
Adding shelf angles or brick ledges at the floor now would obviously be very disruptive. We have wood stud walls, so ended up putting steel columns in to support the lintels. I have worked on had the insulation run up behind the brick.
One thing you can do is specify joint reinforcing in the first couple of courses of brick which tends to make it act like a reinforced masonry beam.
The loose lintel is the problem and it shouldn’t pass throught the rigid insulation to the sheathing. I defy anyone to calculate the exact amount.
This detail works structurally and makes the architect happy. This standard now provides minimum continuous insulation values as well as a total insulation value. It looks like the majority of the time you will need both cavity and continuous insulation. I have dealt with this on one project to date, but it looks like that was just the beginning. I am adding my question here as well.
We have multiple window openings spaced 1ft apart ( 4-5 ft wide windows opening size). I am concerned about vertical load of brick.
I think you need structural steel jambs, providing support for shelf angles rather than loose lintels. The brick pier is carrying a 12’x7′ area of brick. That should be no problem for the pier provided it is laterally braced. Some steel brick angle lintels are also bolted, but again bear on the brick on each side of the opeing. Something has to support that angle. Then, the distance between them can be calculated and decisions can be made to segment the remaining wall length. Vertical movement joint properly located at the end of the beam bottom plate that supports the clay brick veneer at the door opening. This sealant joint prematurely failed because there was no room to install a backer rod for a properly formed sealant joint. Last thing anyone wants is for a brick facade to start to fall down, potentially injuring someone.
