“Build Smart”

THE EARTH IS FALLING APART

India needs to build smarter bridges.

– Protect the People using them.– Save money from having to rebuild

them.

WAYS TO BUILD SMART

TechStar’s Modular Expansion Joint System (MEJS)– Innovations in Design– Strength of Materials– Quality of Fabrication–Monitoring the Device’s Health

A BRIEF HISTORY OF MEJS

TechStar was incorporated in the State of Ohio, USA.

A BRIEF HISTORY OF MEJS

Founders have 100 years collective experience in the development of Expansion Joints.

TechStar has supplied over 12,000 meters of Expansion Joints.

TechStar can supply Expansion Joints for movements up to 2000mm

TechStar has Production Facilities in the USA, Canada, Taiwan, China & India

INNOVATIONS IN DESIGN

All over the world, bridges and buildings are being built in Seismic Active areas. These structures must be equipped

with Modern Technology to protect the Structures, and the people using them.

INNOVATIONS IN DESIGN

The Swivel Joint

INNOVATIONS IN DESIGN

What does a Swivel Joint Do?– In a Swivel Type Expansion Joint, the

Support Bar is able to pivot within the Trumpeted Support Bar Box.

– This allows for the Expansion Joint to move Transversely.

– During Earthquakes an Expansion Joint is forced to move Transversely.

INNOVATIONS IN DESIGN

Elastic Connection

INNOVATIONS IN DESIGN

What does an Elastic Connection Do?– Connection between Center beam

and Support Bar is an Elastic Connection.

– The alternative design welds the two steel beams together.

–With an elastic connection, the friction is dampened, therefore strengthening Expansion Joint.

INNOVATIONS IN DESIGN

Welding?

STRENGTH IN MATERIALS

Durability

STRENGTH IN MATERIALS

The Steel Beam is one piece hot rolled for resistance to fatigue (impact load)

STRENGTH IN MATERIALS

The Support Spring is made of nylon and is not compressible.

Allows the Support Bar position and Center Beam position to be accurately controlled.

STRENGTH IN MATERIALS

Easy Replacement

STRENGTH IN MATERIALS

The Rubber Seal is thinner than competition.

The Control Springs are outside the boxes.

All components of TechStar design are replaceable.

Allows for Fast & Easy Replacement if necessary.
