Safety glass for bridges

Safety glass for bridges

Noise protection and fall protection on bridges can be both highly functional and decorative. Hammerglass AB offers glazing and fastening solutions for all conceivable bridge solutions, including road and railway bridges, as well as pedestrian and bicycle bridges. Thanks to the wide range of fastening methods for installing Hammerglass panels, a bridge can be much more than just a thoroughfare. The use of nanotechnology helps ensure that pollutants from exhaust fumes, oil, and asphalt do not adhere to Hammerglass as easily as they do to conventional glass. The estimated service life of Hammerglass is more than 40 years.

Color and light

Color and LED lighting create an attractive eye-catcher. Hammerglass panels can be screen-printed or digitally printed, offering endless customization options. The panels can be decorated with municipal coats of arms or patterns that repeat at regular intervals. For larger panel series, it is possible to produce color-impregnated Hammerglass. A printed or color-impregnated Hammerglass panel with LED lighting creates an attractive focal point in the darkness of night.

Glass panes for ROAD bridges

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

NOISE PROTECTION

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

• BRIDGE-2: Hot-dip galvanized posts for lateral mounting on bridge posts
  
• BRIDGE-3: CE-marked system for side mounting on the bridgehead
  
• 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 hitting the windows
  

SPRAY GRATING

The robust Hammerglass splash guard was developed for viaducts/intersections with multi-level roadways. The inclined post system is based on the same principle as Hammerglass's electrical safety shields. The structure is typically bolted to the side of the bridge edge girder, but for bridge renovations or new construction projects, the post system can also be mounted with a base plate under the railing post.

Glass panes for railway bridges

Railway bridges typically require particularly stable structural solutions to withstand the vibrations and wind pressure of passing trains. The Hammerglass BRIDGE and GROUND sound insulation systems meet the high stability and safety requirements for installation along railway lines.

SILENCER ON THE WALL

GROUND-2 is a CE-marked noise barrier system with proven solutions for fastening steel and hammer glass. GROUND-2 is designed for wall mounting using screw assemblies.

When the Hammerglass GROUND system is installed on a railway bridge, all barriers are fitted with grounding bars, and each section is grounded separately. A 45-degree bend at the top of the Hammerglass panels reinforces the structure while also contributing to effective reduction of low-frequency train noise.

• A complete CE-marked system with screw groups for mounting in the floor or on walls
• The panels are mounted on the outside of the posts with a robust clamping profile
• Separate earthing of the individual sections
• Angled umbrella top for increased stability
• Height up to 6 meters
• Available with printed patterns to prevent birds from hitting the umbrellas

SILENCER IN THE BRIDGE EDGE GIRDER

When the Hammerglass BRIDGE system is installed on a railway bridge, all barriers are fitted with earthing bars, and each section is earthed separately. A 45-degree bend at the top of the Hammerglass panels reinforces the structure while also contributing to effective reduction of low-frequency train noise.

• BRIDGE-2: Hot-dip galvanized posts for lateral mounting on bridge posts
• BRIDGE-3: CE-marked system for mounting on the side of 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 earthing of the individual sections
• Angled canopy for increased stability
• Height up to 6 meters
• Available with printed patterns to prevent birds from hitting the umbrellas

Passenger walkways

Since the entire construction project is to be carried out while traffic is still running on the tracks, it is necessary that most structures can be fully assembled near the track area and then lifted into position.

Hammerglass's installers install all the panes in place 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 conventional glass, as any movement in the overall structure would result in glass breakage.

All panes are individually measured and manufactured, ensuring smooth installation even if the final design does not correspond 100% to the drawing.

• Tailor-made, individually manufactured discs
  
• Can be glazed on the ground and lifted into position
  
• Minimizes the "draft-free" time

PROTECTIVE SHIELDS FOR RAILWAYS

A modern, electrical canopy structure for covering overhead lines. The electrical shield is strength-calculated to withstand snow and wind loads, as well as the wind load from passing trains. The structure complies with the electrical safety guidelines for electrical canopy structures for installation above railway tracks. The structure blends into the surroundings while forming a solid barrier against live lines.

• 12 mm hammer glass, mounted on a system of angle posts bolted to the sides of the bridge edge girder
• Solid barrier against live wires
• Strength calculation taking into account 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 CE standard EN-14388

PEDESTRIAN AND CYCLE BRIDGE

Flexible solutions for pedestrian and cycle bridges. Installation on existing structures or with a fastening system suitable for the pedestrian and cycle bridge project. The Hammerglass panels are custom-fabricated after the supporting structure is installed.The panes can be supplied clear, opal, colored or printed and can be fitted with LED lighting.

THE ENTIRE BRIDGE CAN BE LIFTED INTO PLACE

To ensure a perfect fit, all measurements are taken after the bridge's steel structure is assembled. This allows all Hammerglass panels to be cut to size in a parallel trapezoid to precisely follow the contours of the floor and skyline.

The Hammerglass panels are manufactured to exact measurements and assembled on-site, either in the factory or at the construction site. Once assembly is complete, the individual bridge sections—or the entire bridge—are lifted into place by crane. Even if the structures are stable, this type of lifting would be nearly impossible with conventional glass, as any movement in the overall structure would result in glass breakage.

With Hammerglass in the design, the time required to close the roadway or track area to install the bridge is reduced to a minimum.

CUSTOMIZED FASTENING SYSTEMS

Hammerglass is happy to actively participate in the construction phase of the bridge to ensure correct fastening and dimensioning.

Once the supporting structure is complete, Hammerglass panels can usually be installed directly into it. If the structure requires additional fastening details, we can help develop suitable solutions.

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

COLOR, PRINT && LIGHTING

The preferred solution for pedestrian and bicycle bridges is a clear or opal hammered glass panel. However, the customization options are virtually unlimited in terms of design, color, and lighting.

• The panels can be screen printed with raster prints or individual patterns to prevent bird collisions
• Hammer glass with blue screen 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 towards the Hammerglass panels for nighttime illumination
• Variable LED creates impressive effects
• For larger series, Hammerglass sheets can be supplied colour-impregnated

Design and assembly

Hammerglass panels are flexible and can be shaped to fit curved profiles. The screen can be tilted at any desired angle, depending on individual requirements regarding sound reflection, light reflection, and snow accumulation. Water drainage can be directed toward the bridge or below the barrier. Include us in your planning right from the conception phase. Our designers will create drawings and propose functional solutions. We are also happy to provide quotes for complete projects: custom-made Hammerglass panels, posts, fastening systems, and installation.
