ANCHORS FOR MASONRY

CONCEALED LINTEL SYSTEMS

Virtually any flat or arched masonry lintel can be accomplished without any exposed steel, using Halfen Anchoring Systems’ concealed lintel system. High-end residential, commercial, and institutional projects can now have all-brick soffit masonry openings that are aesthetically pleasing and maintenance-free. Halfen’s technical department uses the architect’s conceptual design to engineer a lintel support system for each specific opening. Unlimited combinations utilizing different brick size, coursing, span, soffit width, and arch geometry can be designed and manufactured to meet the project specifications. New bolted system is field-adjustable to accommodate brick size variations and construction tolerances. Concealed lintel systems are manufactured from hot dip galvanized carbon steel or stainless steel.

The basic system is manufactured from hot dip galvanized carbon steel (stainless steel also available if specified) and comprises:

  • A fabricated load-bearing spine up to 3/8” [10mm] thick sized to suit opening size, shape and loads, spanning between supporting piers.
  • Horseshoe plates 3/16” [5mm] thick hang over the spine at every third mortar joint.
  • Stitching rods 3/16” diameter x 12” [305mm] long passed through mortar-filled cores in bricks and horseshoe plates to tie the system together.
The basic system is suitable for simply supported masonry openings up to 10 ft [3,050mm] between piers.  For conditions with heavier veneer loads, wider openings and more complicated arch profiles, Halfen can design and manufacture  concealed lintel systems with intermediate supports connected to the building structure.

Other concealed lintel systems can also be provided with brick support brackets fastened directly to structural steel or precast beams within the wall cavity.

BLOCK WALL ANCHORS

Halfen anchor channels and accessories are used in many masonry block applications, including:
  • Restraining masonry block walls to concrete structures.
  • Starter restraints for reinforced masonry block walls, eliminating the unsafe practice of casting-in projecting starter rebars, or drilling and epoxying in rebars.
  • Restraining the top of block and brick walls at the underside of concrete slabs.
  • Providing anchor points for roof trusses at any position around the wall perimeter, when cast into bond beams at top of walls, eliminating preset hold-down bolts that are often misplaced.
  • Installing anchor channels in mortar-filled patches in the faces of block walls to connect equipment or services.
  • Blockwork anchors built into masonry block walls during erection.

SHELF ANGLE SUPPORTS

Halfen’s hot dip galvanized toothed anchor channels can be cast vertically into the face of concrete spandrel beams or slab edges as thin as 5 ½” [140mm]. Steel shelf angles with horizontal slots at the fastening points are bolted to the embeds using toothed tee-bolts. This connection provides vertical adjustment of the shelf angle during installation; once fully fastened, the teeth resist any further vertical movement.
FLEMING MASONRY ANCHORS

Fleming masonry anchors are used to restrain masonry veneer. The system has three simple elements:
  • Anchor Slot 10 ft [3,050mm] long nailed or screwed through sheathing into the framing studs at 16” [405mm] max spacing.
  • Anchors 2”, 3” or 4” [51, 76 or 102mm] long, secured into the tracks at horizontal joint lines at 12” [305mm] maximum vertical spacing.
  • Reinforcement wire at the joint lines containing anchors.
Approved for restraining masonry veneer in seismic zones, the Fleming anchors are available in pregalvanized carbon steel.
