Would expect that the beam should have a fire rating comparable to the wall it passes through.
Roof firewall beam.
E structural 53 56 column beam through penetration walls and floors and joists.
This can be achieved by wrapping the beam with gyp board or by upsizing the beam size.
Roof sheathing deck or slab of a fire resistance rated floor or roof above the ceiling of the corridor shall be permitted to be protected by the use of ceiling materials as required for a 1 hour fire resistance rated floor or roof system.
The ledger is needed to properly attach the perpendicular roof trusses to the top of the structure.
Sheet metal caps offers products for posts beams fences roofs and flashing.
A firewall is an assembly of materials used to separate transformers structures or large buildings to prevent the spread of fire by constructing a wall which extends from the foundation through the roof with a prescribed fire resistance duration and independent structural stability.
One column is used on each side of the fire wall to support the roof system for that building.
This is important because if the beam were to burn through the fire wall would be damaged thus making it ineffective.
Wood framed including dimensional lumber engineered joist and truss.
A firewall is a fire resistive rated wall having protected openings which restricts the spread of fire and extends continuously from the foundation to or through the roof with sufficient structural stability under fire conditions to allow collapse of construction on either side without collapse of the wall.
The firewall parapet in photo 1 appears to be built of masonry.
Walls that are constructed of concrete block that need to be covered with a roof will require the use of a ledger.
Both steel columns and primary support beams trusses should be aligned vertically and horizontally with the columns and beams trusses on the opposite side of the wall and should be fireproofed.
And to extend above the roof of the tallest building.
Section 706 5 2 states that firewalls shall extend to the outer edge of horizontal projecting elements such as balconies roof overhangs canopies marquees and other similarbuilding projections that arewithin 4 feetof the firewall.
D horizontal membrane 52 shaft wall used in a horizontal plane.
There are provisions for this in the code.
This allows a building to be subdivided into smaller sections.
To extend beyond the face of the perpendicular walls.
