Expansion Joint Opens Horizontally at the Middle of the Bridge. MAURER creates unique solution for the Clyde Crossing in Glasgow. The new Clyde Crossing in Glasgow is a double swing bridge that opens at the centre, thanks in part to the special expansion joint from MAURER (Type DS 4 HL). With its unique hydraulic system, it can control the opening and closing of the bridge, as well as compensating for expansions caused by temperature, wind and traffic load like a conventional expansion joint. The Clyde Crossing is Scotland’s latest iconic feat of engineering. It crosses the River Clyde in the Glasgow suburb of Yoker and connects the neighbouring towns of Clydebank and Renfrew. The imposing white steel bridge consists of two swing bridges and was built by a joint venture between JV Hollandia Infra (southern half) and Smulders Iemants (northern half). Two pairs of pylons close to the river bank extend outwards like cranes and pivot with the bridge when it opens. The Clyde Crossing is 184 m long and 12.3 m wide, making it suitable for vehicles, pedestrians and cyclists alike.     #expansionjoints #expansionjoint #bridges #bridge #construction #architecture

This issue e-mosty-June24.pdf  is exceptional and describes in detail the two outstanding bridges in North America, the New Champlain and Pattullo bridges, with MAURER expansion joints. Additionally, The Gerald Desmond and Peljesac bridges, 2 more remarkable bridge projects in which we were involved, are also mentioned.

Special Bearings and Noise Reduction for Leverkusen Special restraints for the bearings and noise reduction on the expansion joints – MAURER supplied high-quality special elements for the first new section of the bridge over the Rhine in Leverkusen. The previous Leverkusen Rhine bridge on the A1 motorway had been in operation since 1965, and due to cracks in the steel loadbearing structure, could only be used by vehicles of up to 3.5 tonnes at a maximum of 60 km/h since 2014. This caused major traffic problems in the region, as delivery traffic had to use other bridges. Since February 2024, the problem has been partially alleviated. The first cable-stayed bridge – of two directional lanes – of the replacement construction was inaugurated and now carries the entire traffic of 150,000 vehicles per day. The bridge is a total of 1,068.5 m long (main bridge 690 m) and has two distinctive A-shaped pylons. The width of over 33 m is currently used for three narrowed lanes in each direction towards Koblenz and towards Dortmund. In future, it is designed for four lanes, two access and exit ramps plus hard shoulder and a 3.25-metre-wide cycle path. The old bridge with the reddish stays is currently being dismantled. From 2025, the second parallel section of the bridge is planned to be built and inauguration is scheduled for 2027.   #brigdes #construction #expansionjoints #engineering

The Kocher Viaduct is equipped with modern sliding bearings instead of rollers. As part of the rehabilitation of the A 81 federal motorway at the Kocher Viaduct, MAURER replaces the old roller bearings made of stainless steel with modern spherical segment bearings. The patented bearing type was developed precisely for this application and is approved by a European Technical Assessment. The Kocher Viaduct is a nine-span prestressed concrete box girder bridge at a total length of 478 m. In order to prepare it for future requirements, it is strengthened with an external prestressing and equipped with new expansion joints, among other things. Another very important measure is the replacement of the existing bearings with modern sliding bearings. The roller bearings in the structure were replaced with 24 spherical segment bearings with a vertical force of up to 19 MN, 16 spherical bearings, and 2 horizontal force bearings.   #brigdes #construction #engineering

Insights into current projects and an outlook for the future

Detachable Anchorage for Expansion Joints The first section of the new Duisburg-Neuenkamp Rhine Bridge is already open to traffic, but it will not stay where it currently is. A spectacular transverse displacement is planned for 2026, which will also include the expansion joints. MAURER therefore designed special detachable anchorages for the southern superstructure so that they can be moved with the transverse displacement in 2026. There has never been a transverse displacement of expansion joints of this size before. Here, the challenge did not lie in the movement of up to 900 mm. MAURER has already built and displaced expansion joints before, which allowed for much larger movements. It was the special geometry of the expansion joints that proved to be rather intricate: they have a varying transverse slope and an enormous length at up to 48 m. MAURER supplies a total of eight expansion joints for the new Rhine bridges: XLS 900 and XLS 400 for the main lanes as well as XLS 900 and DB 130 for the dedicated foot and cycle paths alongside them. #brigdes #construction #expansionjoints #engineering

Sliding Isolation Pendulums Protect a Wooden Wave-Shaped Airport Roof New main terminal at the Portland International Airport is equipped with seismic isolation bearings The appearance is stunning: a wooden roof floats above the reconstructed and expanded Portland airport terminal. Y-columns support the roof. The visionary design became earthquake-resistant using 68 double concave SIP®-Bearings, which sit on top of the Y column tines: posing a challenge to MAURER’s experts in seismic protection. In a multi-year project, the main terminal of the Portland International Airport (PDX) in Oregon, USA, was expanded, renovated and equipped with seismic protection. The existing buildings are not designed for the newly applicable specifications and earthquake intensities. The approximately 32,500 m² new timber roof will be visually distinctive. The roof shape is modelled on sea waves, a design of ZGF Architects and KPFF Consulting Engineers. The roof rests on 34 approximately 16.2-metre-high steel Y-columns filled with concrete, which are arranged at a distance of more than 30 metres. “Overall, however, it was not only about the design of our bearings. The requirements for movements and superimposed loads in a highly confined space could only be met with our high-performance sliding material MSM®,” reports Mark Kaczinski, MAURER USA. MSM® stands for MAURER Sliding Material. In contrast to the alternative PTFE used, it is PFAS-free. MSM® also has a much longer service life (more than 50 years) and double the compressive strength. The bearings can therefore be built smaller and the largest have a maximum diameter of only 1,000 mm.     #construction #architecture #design #building #engineering

We are pleased to introduce you to our production facility in Torbali, near Izmir in Turkey.  We will show you the entire production process from the raw material to the final product and we highlight the installation of our products on the construction site.
