Structural Punched Metal Studs or Joists – the Key to the Technology

• The Bi-Directional Shear Tabs bond to the concrete • Composite Walls or Floors are fabricated utilizing bonded Concrete & Steel • Synergy of the Composite exceeds the performance of the individual components by 65%

Engineered Composite HTT Floor System Stronger than Deck & Joist Assemblies

• HTT Composite Bonded Floor Joist and Concrete provides 65% greater structural efficiencies at 24” o.c. spacing • HTT Floor Joists take advantage of the concrete to add strength to its members rather than just being dead load to non-composite joists or trusses @ closer spacing • 65% increase for HTT Floors in Strength & Stiffness as compared to non-composite floor systems

HTT Floor Framing & Forming

• HTT Exterior Structural Walls • HTT Floor Joists w/ Shear Tabs • Plywood Forms between Joists • Floor Joists @ 24” o.c. • Long structural spans

Concrete Pumping & Finishing - HTT Finishing of the Structural Slab is similar to any other slab. Large areas can be easily finished with troweling machines.

HTT Floor System uses 6-7” slump concrete, typically pumped from a grout pump to eliminate heavy excesses and better flow control with less men.

Floor Joist spans should be shored at mid-point until the concrete pour is placed and cured. Once the concrete is cured the composite performance is completed and shoring can be removed.

HTT Exterior Load Bearing Walls & Upper HTT Floor System Pour Typically, HTT Floor System is

connected to & supported by HTT Wall System via structural track and clips. These connections are engineered with the floor system, wall system and overall building structure.

Edge blocking at floor section sides. The HTT Floor Joist System offers longer spans with smaller joists at 24” centers.

HTT Cantilevered Balconies

6 foot deep Cantilevered HTT Balconies

Cantilevered from the HTT floor joist structure, the 6 ft deep balconies offer more luxury space to apartment life that is frequently omitted due to structural costs and impracticalities. Competing structural systems require masonry or steel columns to adequately support such balconies. Offerings are often 4 feet or less in depth which are nearly unusable.

HTT 3rd & 4th Story Panels erected and braced to 3rd Story HTT Floor System

Here you see a large 2 Story Flag shaped HTT panel erection, stacking on top of a 2 Story HTT panel. As with the other 3rd & 4th story wall panels, these are braced to the composite HTT Floor System on the 3rd Floor. These panels are welded or bolted to the floor structure also. Once the upper floor framing is installed and connected, the braces can be removed. Combined with interior load bearing walls or frame, this concept allows faster mid-rise envelope construction.

Unique Components from HTT Framing Extended Balcony joists cantilever 6 feet; Stair landings are framed and poured in HTT floor joist system and support prefabbed metal stairs

Piping & Insulation in HTT Walls

• Electrical Conduits • Plumbing Risers • Communications Cabling & Conduit • Blocking for Hardware • Blocking for Accessories • Insulation Materials – many options • R-Values from R-13 to R-26 or > • Interior Finish – many options • Fire Rated Panels – 1 hr - 4 hr ratings

Window Details in HTT Walls

Flush mounting finless windows are shimmed and anchored in place with ¼” perimeter sealant joint. Position and recess are determined by the wall depth and the concrete return on head, jambs and sill.
