Mini-V Connector

A shear/alignment connection typically used in 2-inch field-topped double tees

Typically used in field-topped double tee flanges and wall panels; available in both J-Finish or stainless steel.   Various size blockouts are available for flexible installation – 1/4″, 3/4″, 1″ inch, or flush. 

  • Available in 201L stainless steel and high strength low alloy carbon steel with J-Finish

  • Extensive published test reports to validate performance and recommended capacities
  • User guidelines available below for engineering, purchasing, production and erection
Overview

In 2001, three years after the release of the Vector Connector for 4-inch minimum pre-topped double tees and wall panels, we initiated another search for  state-of-the-art shear/alignment connections for connecting 2-inch field-topped double tees and wall panels. Once again, finding virtually no testing data and only one standard connection on the market, we invented a new shear/alignment connector – the MINI-V SHEAR CONNECTOR.

Rigorous testing at the University of Wisconsin School of Engineering testing lab yielded dramatic results. The results obtained were extremely consistent and the ultimate values were higher than anticipated. The MINI-V SHEAR CONNECTOR offers a level of documented performance and consistency that – prior to its invention – was simply not available.

Benefits
  • The Mini-V Shear Connector is designed for use in a minimum of 2″ thick precast concrete.
  • Two styles are available: Square Mini-V (vertical faceplate) and Angle Mini-V (10 degree faceplate slope).
  • Available in J-Finish or stainless steel.
  • Non-welded monolithic construction.
  • Sits on or above mesh for easy production installation.
  • Folded design offers a desirable ductile failure mode.
  • Helps eliminate spalling or cracking during field welding.
  • Cost effective.
  • Eliminates expensive remedial “fixes”.
  • Adaptable for seismic applications.
  • Documented test data.
Products Mini-V can be used in are:
  • Wall Panels.
  • Field Topped Tees.
  • Roof Tees.
  • Prison Cells.
  • Any product that can utilize shear/alignment connections.

Overview

In 1998, in response to feedback from the precast industry, JVI initiated a search of the state-of-the-art in flange connections (A flange connector is an anchored weld plate in the flange of a double tee used to connect double tees within a structure). Finding virtually no testing data and only one standard connection on the market, JVI invented a new flange connector – the VECTOR CONNECTOR.

Rigorous testing at the University of Wisconsin School of Engineering testing lab yielded dramatic results. The tension and shear values obtained were vastly superior to other connectors tested. Subsequent tests by separate precast producers in their own plants have confirmed these values. To date, more than 12 million vector connectors are in service in precast products throughout the world.

Benefits
  • Made in the USA.
  • Cost effective.
  • 1 1/2″ tall faceplate with labeled weld zone.
  • Successfully tested to full capacity with 2 1/2″ weld.
  • Patented face sweep and bend to promote flexibility in tension.
  • Extensive, published test reports to validate recommended capacities.
  • Horizontal legs at installation eliminates reinforcing interferences & centers the legs.
  • User guidelines available for engineering, purchasing, production and erection procedures.
  • 201 LN Stainless Steel and J-Finish Carbon Steel connectors in stock and ready for shipping.
  • Non-welded monolithic construction.
  • Blockouts Eliminates spalling or cracking during field welding.
  • ¼: 4 slope of reversible face plate accommodates both positive and negative positions.
  • Eliminates expensive remedial ‘fixes’.
  • Adaptable for seismic applications.
  • Industry standard for 15+ years with over 12 million Vectors Connectors in service around the world in all types of building systems where shear and alignment connections are required.
