Safety glass for bridges

Safety glass for bridges

Noise protection and fall protection on bridges can be both highly functional and decorative at the same time. Hammerglass AB offers glazing and fastening solutions for all conceivable bridge solutions for roads and railways, as well as for pedestrian and bicycle bridges. Thanks to the wide range of fastening methods for the installation of Hammerglass panes, a bridge can be much more than just a passageway. The use of nanotechnology helps ensure that pollutants from exhaust gases, oil, and asphalt do not adhere as easily to Hammerglass as they do to ordinary glass. The estimated lifespan of Hammerglass is more than 40 years.

Color and light

Color and LED lighting create an appealing focal point. The Hammerglass panes can be printed using screen printing or digital printing techniques, allowing for limitless individual design possibilities.The panes can be adorned with municipal coats of arms or patterns that repeat at regular intervals. For larger plate series, there is the option to produce colored impregnated hammer glass. A printed or color-impregnated hammer glass pane with LED lighting creates an attractive light point in the nighttime darkness.

Glass panes for ROAD bridges

No two bridges are alike. In densely populated areas, a noise-reducing solution is often required, while in other cases, a splash guard or fall protection may be preferable.

NOISE PROTECTION

The BRIDGE-2 and BRIDGE-3 systems are complete noise barrier wall systems for installation on bridges along roads or railways. Depending on the design of the bridge, the constructions are attached to the bridge posts or laterally to the bridge edge beam.

• BRIDGE-2: Galvanized posts for lateral mounting on bridge posts
  
• BRIDGE-3: CE-marked system for lateral mounting on the bridge head
  
• The Hammerglass panels are mounted on the outside of the posts with an external support plate and a robust clamping profile
  
• Height up to 6 meters
  
• Printed patterns prevent birds from colliding with the panes
  

SPRAY GUARD

The robust Hammerglass spray guard has been designed for viaducts/intersections with multi-level roadways. The angled post system is based on the same principle as Hammerglass's electric shields.The construction is usually screwed to the side of the bridge edge beam; however, in bridge renovations or new construction projects, the post system can also be mounted with a base plate under the railing post.

Glass panels for RAILWAY bridges

Railway bridges generally require particularly stable construction solutions to withstand the vibrations and wind pressure from passing trains. The Hammerglass BRIDGE and GROUND soundproofing systems meet the high demands for stability and safety when installed along railways.

SOUND DAMPER ON THE WALL

GROUND-2 is a CE-marked noise protection wall system with proven solutions for fastening steel and Hammerglass. GROUND-2 is designed for installation on walls using screw groups.

If the Hammerglass GROUND system is installed on a railway bridge, all barriers are equipped with grounding rails and each section is grounded separately. A 45-degree curvature at the top of the Hammerglass panels reinforces the structure while also contributing to an effective reduction of low-frequency noise from trains.

• A complete CE-marked system with screw groups for installation in the ground or on walls
• The panels are mounted on the outside of the posts with a robust clamping profile
• Separate grounding of the individual sections
• Angled screen top for increased stability
• Height up to 6 meters
• Available with printed patterns to prevent birds from colliding with the screens

SILENCER IN THE BRIDGE EDGE BEAM

When the Hammerglass BRIDGE system is installed on a railway bridge, all barriers are equipped with grounding rails and each section is grounded separately. A 45-degree curvature at the top of the Hammerglass panels reinforces the structure while also contributing to an effective reduction of low-frequency noise from trains.

• BRIDGE-2: Galvanized posts for lateral mounting on bridge posts
• BRIDGE-3: CE-marked system for lateral mounting on the bridge girder
• The Hammerglass panels are mounted on the outside of the posts with an external support plate and a robust clamping profile
• Separate grounding of the individual sections
• Angled canopy for increased stability
• Height up to 6 meters
• Available with printed patterns to prevent birds from colliding with the canopies

PEDESTRIAN BRIDGES FOR PASSENGERS

Since the entire construction measure is usually to be carried out while traffic is ongoing on the tracks, it is necessary that most constructions can be fully assembled near the track area and then lifted into position.

The installers from Hammerglass mount all panes on-site while the steel skeleton is on the ground, and then lift the entire structure into position. This type of lifting would be almost impossible with ordinary glass, as movements in the overall structure would lead to glass breakage.

All panes are individually measured and manufactured, ensuring that installation proceeds smoothly even if the final construction does not match the drawing 100%.

• Custom-made, individually manufactured panes
  
• Can be glazed on the ground and lifted into position
  
• Minimizes the "stress-free" time

PROTECTIVE SHIELDS FOR RAILWAYS

A modern, electric protective roof structure for covering overhead lines.The electric protective shield is structurally calculated for snow and wind loads as well as for wind loads caused by passing trains. The construction complies with the electrical safety guidelines for electric protective roof structures for installation over railway tracks. The construction integrates into the environment while simultaneously forming a solid barrier against live electrical lines.

• 12-mm hammer glass, mounted on a system of angle posts that are bolted to the side of the bridge edge beam
• Solid barrier against live electrical lines
• Strength calculation considering snow and wind loads as well as wind loads from trains
• Waterproof and tamper-proof
• Execution class EXC2 or EXC3
• Meets the requirements for noise barriers set out in the CE standard EN-14388

PEDESTRIAN AND CYCLIST BRIDGE

Flexible solutions for pedestrian and cyclist bridges. Installation on existing structures or with a fastening system suitable for the pedestrian and cyclist bridge project. The hammer glass panels are custom-made after the load-bearing structure is installed. The panes can be supplied clear, opal, colored, or printed and can be equipped with LED lighting.

THE ENTIRE BRIDGE CAN BE LIFTED INTO PLACE

To ensure that the panels fit perfectly, all measurements are taken after the steel structure of the bridge has been assembled. All Hammerglass panels can therefore be manufactured to size in a parallel trapezoid to precisely follow the contours of the ground and the skyline.

The Hammerglass panels are custom-made to the exact dimensions and installed on-site directly at the factory or construction site. Once the installation is complete, the individual bridge components - or the entire bridge - are lifted into place with a crane. Even if the structures are stable, this method of lifting with ordinary glass would be nearly impossible, as movements in the overall structure would lead to glass breakage.

With Hammerglass in the construction, the time during which the roadway or track area must be closed to install the bridge is minimized.

CUSTOMIZED MOUNTING SYSTEMS

Hammerglass is pleased to actively participate in the construction phase of the bridge to ensure proper mounting and sizing.

Once the load-bearing structure is completed, Hammerglass panels can usually be installed directly within it. If the structure needs to be supplemented with mounting details, we assist in developing suitable proposals.

If the customer desires a customized solution, our designers provide their expertise to create creative proposals, construction drawings, and strength calculations.

COLOR, PRINT & LIGHTING

The preferred solution for pedestrian and bicycle bridges is a clear or opal Hammerglass panel. However, the possibilities for individual design are largely unlimited in terms of design, color, and lighting.

• The panels can be printed using screen printing with raster prints or custom patterns to prevent bird collisions
• Hammerglass with blue raster printing and LED lighting creates a bridge that is transparent during the day but glows blue in the evening darkness
• The LED lighting in the handrail can be directed onto the Hammerglass panels for illumination at night
• Variable LED creates impressive effects
• For larger series, Hammerglass panels can be delivered with colored impregnation 

Design and Installation

Hammerglass panes are flexible and can be shaped accordingly to fit into curved profiles. The screen can be tilted at any desired angle, depending on individual requirements regarding sound reflection, light reflection, and snow accumulation.The water drainage can occur towards the bridge or below the barrier. Please include us in your considerations during the idea phase. Our designers create drawings and make suggestions for functional solutions. We are also happy to provide you with offers for complete projects: Hammerglass made to measure, posts, fastening systems, and installation.
