Featured Project: SPS “Sandwich Plate System” Used on Germany’s Mettlach Bridge - back to top
The 1951-vintage suspension bridge crossing the river Saar in Germany at Mettlach needed refurbishing to meet current highway safety standards. The bridge is located in unique “Saarschleife” tourist region and connects the districts of Mettlach and Keuchingen with a double span of 108 m. This is an important traffic connection in the area for which a total closure was not allowed. In the 1950s the bridge was a pioneer project for light design. It originally received a light steel-concrete composite deck supported by a steel girder and cable structure. Due to wear, corrosion and high traffic, the structural load carrying capacity was reduced. SPS (Sandwich Plate System) was chosen as the best solution to reinstate and upgrade the bridge to current standards.
SPS is a structural steel material that is stronger, more versatile and accurate than concrete. The Sandwich Plate System is a composite material comprised of two metal plates bonded with a polyurethane elastomer core and is 75% lighter than an equivalent-strength concrete deck. SPS transfers shear between each plate and eliminates the need for stiffeners while precluding local faceplate buckling. SPS was originally designed to protect drilling islands in the Arctic Beaufort Sea from ice floes and has been in use for over 18 years. SPS has since evolved as a product of choice for architects and engineers around the world for a variety of engineering projects.
With nearly 3 million square feet in use, SPS can be found in the mezzanine floors of New York’s historic Carnegie Hall, the terraces of the 2012 London Olympics Aquatics Center, roof structures & building floors and as a strengthening method for ship hulls and decks. There are many conventional and orthotropic bridge decks in countries around the world that have been improved by SPS technology. Some SPS Bridge Deck installations have more than 350 million fatigue cycles without incident.
Eiffel Deutschland Stalhbau (EDS) together with Intelligent Engineering (IE), inventor of SPS along with the support of RWTH Aachen in Germany developed details and designs in accordance with the appropriate Euro Codes and have now applied these designs to build the 3rd SPS bridge in Germany. SPS is able to replace orthotropic bridge decks with a new design that has enhanced structural performance. SPS is an isotropic plate with damping and vibration insulation characteristics that also reduces traffic noise emission.
By using the SPS deck, the Mettlach bridge weight was reduced from 500 tons down to 200 tons making it possible to increase traffic loads to current standards while relieving stress in the cables. The slim design of SPS is also only a quarter of the depth of the original orthotropic deck. The replacement strategy was developed within a short 4-month construction schedule. Importantly, there was no full closure as one full traffic lane was maintained. Construction phases for both lanes separately began in November, 2012 and were successfully completed in February, 2013.

Construction Stud Welding - back to top
OVERVIEW
Stud welding meets a broad variety of fabrication and construction requirements. It is fast, easy and strong and provides a lower installed cost when compared to other fabrication methods.
PROCESS DESCRIPTION
The stud welding process is similar to the stick welding process; however, unlike the stick welding process, stud welding is automated and can be performed by operators not trained in the welding field.
The operator loads a stud and a ceramic shield into the welding tool. (The ceramic shield serves to contain the molten pool of steel during the welding process.) The operator places the stud tip against the work piece and presses the trigger. The power supply then operates the internal mechanism in the weld tool (often called a gun). The tool creates a lifting action which is analogous to striking the arc in stick welding. The power supply provides the necessary weld current to sufficiently melt the stud and the base material. The power supply maintains this arc for the appropriate duration (typically less than one second) and then plunges the stud into the molten pool of steel created by the arc. The ceramic shield (ferrule) molds the molten pool of steel until the steel cools and then the ceramic shield is broken and discarded. This automatic process means that the welding of fasteners is extremely fast. In a time where labor costs are a significant factor - if not the significant factor- in a job, any labor savings is appreciated by the fabrication shop.
STUD WELDING CONSTRUCTION APPLICATIONS

||
Because the weld produced by the stud welding process offers high structural integrity, excellent productivity and many other benefits, it is used extensively in a wide range of construction applications, including:
Bridges: The shear stud is welded onto a bare I-beam used in steel bridge construction. When the concrete is poured the shear stud interlocks the steel and concrete together.
Deformed Bar Anchors (DBA) are used to provide anchorage with surrounding concrete. Unlike conventional deformed bar (re-bar) DBA’s are weldable using the stud weld process. This means anchorage can be welded quickly and reliably into a wide variety of spaces and surfaces.
Embed Plates: Studs are welded to the back of a plate and are embedded into material. This can be concrete in tilt up wall construction or it could be earth in a retaining wall application.
Through Deck (Thru Deck): In multistory steel building construction, shear studs are welded through the steel decking. This joins the shear stud, steel deck and I-beam together. Once the concrete is poured, it too is interlocked to the steel structure by the shear stud. This is commonly referred to as composite beam construction. This approach can allow for smaller beam webs and/or greater spans between beams. This can add up to significant cost savings for the steel erector.
Threaded Studs: Threaded studs also have their place in construction and fabrication. They are used in window retention (Rock & Roll Hall of Fame) and drop ceiling applications and wire way routings as well as many other applications.
STUD WELDING EQUIPMENT
The stud welding equipment is composed of a few key pieces:
- Power Supply to generate the weld energy
- The weld tool (gun) which is used to automatically strike the welding arc and hold the fastener during the welding process
- The proper accessories that are suited to the particular welding application
- Cables that run between the power source and the weld tool. The cables can become a critical component if they are undersized or if a user attempts to put too much cable onto a power supply that cannot handle the cable load.
While these components do not appear complex, like any system, they require the proper maintenance and care to ensure maximum job uptime.
MAKING THE DECISION
To determine whether stud welding is the optimum metal fastening method for your requirements, analyze your specifications and consider such factors as productivity, quality, aesthetics and engineering assistance. If appearance is important, compare stud welding’s onesided fastening process with twosided processes. When comparing welding times between processes, be sure to compare the steps involved in one process versus another to reach an accurate assessment of productivity rates.
If you have selected the stud welding process, consider the following qualifications when choosing a studwelding partner.

New ZT Universal Harness Includes Additional Safety Features - back to top
|
 |
The ZT Universal Harness is the latest in the award-winning ZT product range. The Universal offers five-point attachments: front, rear and side loops for work positioning. It incorporates the ZT leg gaiter design, which completely eliminates the use of groin straps and the serious damage they cause when restricting the femoral artery in the groin area during prolonged suspension.
The harness combines an integrated harness and lanyard with performance work-wear trousers or coveralls. It employs a patented leg gaiter system with lanyard and front point attachment. The elimination of loose straps or lanyards means there is no risk of catching these on door handles or wing mirrors when entering or exiting a vehicle. There is no metal 'D' ring so it's also comfortable to wear when driving. Restraint or shock absorbing lanyards can be connected easily to the harnesses front or rear point attachment.
The universal harness is an essential piece of height safety equipment that can be worn as a fall restraint or fall safety harness with the added benefit of work positioning loops. Between work at height tasks and during breaks, the lanyard can be removed and stowed without the need to need to remove the harness or change.
The harness is certified to 330 lbs in body weight as well as being certified to EN361:2002 and EN358 standards.
ZT Safety has also introduced a new range of jackets, winter suits and body warmers specially designed to be worn in conjunction with its harnesses.
OSHA and National Weather Service Team Up to Protect Workers from Heat Illnesses - back to top
At a recent training in West Springfield, Mass., an OSHA area compliance specialist
educated a class of 37 immigrant workers from Somalia, Bhutan, Iraq, Burma and
Nepal about the hazards of working in heat along with other workplace safety issues.
OSHA and the NOAA National Weather Service are teaming up again to prevent heat-related deaths and illnesses. Record-breaking heat the past two years has exacerbated heat-related injuries and fatalities in outdoor workers. With summer heat continuing, Assistant Secretary of Labor for Occupational Safety and Health Dr. David Michaels and NOAA's National Weather Service Director Dr. Louis Uccellini are reminding employers that heat-related illnesses can be prevented.
"Each year, thousands of workers across the country suffer from serious heat-related illnesses," said Michaels. "This can easily be prevented with water, rest, and shade. If outdoor workers take these precautions, it can mean the difference between life and death."
In 2011, 4,420 workers experienced heat illnesses and 61 workers died according to the Bureau of Labor Statistics data. To help prevent heat related deaths and illness among workers, NOAA will continue to include the following language in its excessive heat warnings that are sent across the country:
