HYBRID COLUMN & BEAM
The precision and speed of precast concrete combined with the strength of poured-in-place columns and beams.
This innovative building concept and resulting technology provides a cost-effective alternative to traditional column
and beam construction. Precise, one-piece forms have adustable block outs for casting column and beam element
of varying sizes. Insulated forms and blanket covers allow a daily casting cycle without electric or steam heat.
U-shaped precast concrete hybrid elements are joined to create the exterior shells for cast-in-place columns.
Minimal shoring and bracing are required. Elements have a smooth, clean finish with no additional plastering needed.
HOW IT WORKS
Beam elements are cast within the same hybrid mold and set on the erected precast columns. Bracing and
steel-angle clamps are used at the top and bottom of each column form to provide temporary diagonal bracing and lateral
support to the system. Waffle-Crete floors are structural spans that use half the concrete and steel required by conventional
solid cast floors. Floor panels are set and bolted to the beam elements. Panel surfaces are smooth and level, requiring no
additional topping. Lighter weight floors result in less building weight and smaller, less expensive foundations. Precast Hybrid
column and beam elements are cast with shear keys to provide complete shear transfer between cast-in-place and precast
concrete. They become a structural part of the reinforced poured-in-place column and beam. The column and beam grid for each
floor level is poured at one time, tying all precast elements, poured-in-place columns, beams, and floor panels together.
Hybrid Molds produce precast concrete elements that become an integral structural part of poured-in-place column and beam
grids. The system can be designed as a Special Moment-Resisting Frame System or a combination of shear walls and Special
Moment-Resisting Frame for structures in areas of severe seismic activity and high wind loads.
This system casts both column and beam elements in
the same mold. Molds are made with rugged, reinforced
insulated heavy duty plastic and sturdy, rustproof
aluminum. Molds are then cured overnight without any
external heat. They produce low-weight precast
elements precisely, every time.
HYBRID BUILDING SYSTEM
Requires smaller and less expensive foundations.
Precisely dimensioned precast elements eliminate
plastering. It greatly reduces bracing and shoring
along with labor requirements. There is less lumber
waste and the construction process goes faster.
Overall creates a cleaner, safer, and open
Our system builds a strong, well-constructed building.
These buildings are made 50% faster with only 20% of
the workers. The weight of building materials is
reduced by 30% or more. Usage of formply and
dimensional lumber is reduced by 90%, as well as reducing
the amount of concrete and steel needed by more than 30%.
