Bridge Solutions

Structural bearings are important elements of structures, especially in large infrastructures such as bridges, heavy buildings, high-rise buildings, ensuring load transfer, movement, rotation, vertical and horizontal restraints as required by the design at critical locations in a structure.

i. Elastomeric bearings for low and moderate loads.

ii. Pot bearings, for higher loads. They might accommodate small rotations.

iii. Spherical bearings, for high loads and high rotation requirements.

iv. Special bearings, including shear keys, up-lift systems integrated in bearings, temporary ILM bridges, and seismic bearings.

Elastomeric Bearings are designed for use in bridge and building construction – under pre-cast concrete beams, steel beam supports and other support points – as local load carrying components.

REiNWEL® provides application services to virtually every type of Elastomeric Bearings covering:

High capacity Steel Plate Laminated Bearings

Elastomeric Laminated Bearings are designed for use in bridges and similar types of structures. They act as a load transfer element that is capable of supporting a vertical force whilst simultaneously absorbing horizontal and rotational translations that may occur.

REiNWEL offers an application of 3 grades Steel pot bearing

  • Fixed
  • Guided
  • Free

Standard Reinforced Bearing Pads and Strips.

Generically referred to as a “reinforced” Bearing Pad or Bearing Strip, they are pressure molded from a high-quality Natural Rubber of 60 IRHD hardness.

These elastomeric bearing pads provide an economical solution to problems caused to a structure by static and dynamic effects of traffi c or wind / variations of temperature, creep, shrinkage or pre-stressing / vibrations and impacts. The pads provide freedom between two elements of a bridge structure absorbing stresses from horizontal and vertical loads and rotations.

REiNWEL Structural Solutions can facilitate the provision of specialist installation teams to undertake site inspection, installation, repair and maintenance activities associated with all expansion joints and seals.

Our well respected teams consist of highly trained and experienced installers led by technically qualified engineering personnel that work closely with our customers. Our own in-house engineering design and manufacturing capabilities ensure we have the most effective, innovative and cost efficient outcomes within the industry.

Expansion Joints – Small Movements

These designs are suitable for multi-level car parks, plaza decks, pedestrian bridges, and other applications that are pedestrian intense.

i. Strip Seal Expansion Joint System

ii. Polymer Nosed Expansion Joint System

iii. Aluminum Expansion Joint System

iv. Compression Seal

v. Two Part Silicone Seal

Expansion Joints – Large Movement

Large movement expansion joints are best defi ned as those that provide support across the expansion void, without exceeding the code requirement of the 85 mm ULS unsupported gap. Large movement expansion joints, particularly of the Modular type having movement capacities up to 2,000mm, require careful consideration as to the structural integrity of the bridge in this

highly stressed area. Typical block out depth is in the order 0f 400mm. Careful consideration is required early in the design process. Consultation with REiNWEL engineers is recommended.

Using its experience in the specification and design of bridge solutions, combined with its extensive

structural engineering expertise, REiNWEL is in the unique position to be able to design bespoke

Post-tensioning bridge decks to meet clients’ requirements, offering an improved level of operational

flexibility and accommodating the client’s needs.

Deck Tension Services:

Transverse deck post-tensioning

Done to strengthen the deck slab in direction perpendicular to traffi c flow. Its purpose is similar to longitudinal post-tensioning, only the direction of application is different. It is usually done in bridges where the deck width is large, which makes it diffi cult to design the deck slab.

Longitudinal post-tensioning

Longitudinal post-tensioning helps keep the precast bridge deck in compression and avoid problems such as leaking, cracking, spalling, and subsequent rusting on the beams at the transverse panel joints.
