ADVANCING THE CONSTRUCTION INDUSTRY
Adobe formatted versions of
BauGrid® patents
-
US Patent No. 5,218,809 - Earthquake Resistant Structure Utilizing a
Confinement Reinforcing Framework
-
US Patent No. 5,392,580 - Modular Reinforcement Cages for Ductile Concrete
Frame Members and Method of Fabricating and Erecting The Same (BauGrid®
Reinforcement System), European, Japanese and Mexican Patents Pending
The Problems
|
The Solution
|
The Assurance
|
- Reliable ductility
(Toughness)
- Hoops with poor
dimensional tolerances
- Installing rebar
hooks is labor intensive
- Placing concrete
around hooks is very difficult and time consuming
- Rebar hooks can be
unreliable
|
- Welded grids using
high strength wire
- Fabricated in a
welding fixture to 1/8" tolerance
- Shipped in compact
bundles
- Labor saving
instillation into cage rebar
- More accurate
positioning
- Gives more consistent
confinement the full length of the member
- Saves crane time and
erection labor
- Greater ductility =
Less force = Less rebar
- More reliable
ductility = Safer buildings
|
- Precision fabricated
- In plant, on-line
testing
- Proprietary welding
techniques
- Cross-wire
confinement at each rebar
- More reliable
confinement
- Improved ductility
