Product Description
DBHRS-R2~DBHR-RS30
Key Features
1. Summary
The hybrid Replacement System(DBHRS) expansion joint has a
similar function and structure to the Rail type expansion joint
(DBR), but it can address the maintenance and replacement
challenges that DBR faces.
It is an innovative technology product that can replace and
maintain only damaged steel members while maintaining the
existing concrete structure of the expansion joint.
This technology eliminates construction processes such as
reinforcement bar placement, concrete removal and cast in, and
concrete curing. It provides shorter construction periods and
cost savings compared to traditional products, extends the life
of bridges, and improves stability and durability.
2. Features
The waterproof rubber seal between rail beams is put in the rail
groove processed in the same way as a rubber seal, playing its
waterproof role perfectly. So it secures the durability of the
lower structures of bridge. The spacing system installed on the
bottom of rail beams equally distributes the whole expansion
behavior. For the semi-permanent use of structural steel parts,
elastic parts with excellent attenuation are applied. It is
possible to make continuous use only by replacing
parts.
Rail Type Expansion Joint uses only the parts that passed strict
tests. So, it is possible to endure various environmental and
physical conditions during the endurance life of bridge. In
addition, the expansion joint is applicable regardless of a
bridge type. In short, it is usable without the limitation of
expansion length (at least 120 mm).
The gap between rail beams is max. 80mm according to field
conditions. The number of rail beams and the number of waterproof
rubber seals depend on expansion length.
• During the initial installation, an open support box is
installed, allowing for efficient maintenance by only replacing
the main body in the event of expansion joint damage.
• Partial lane-by-lane replacement is possible, enabling
efficient maintenance management.
• The replacement time is significantly reduced compared to
former replacement methods.
• There is no need to dismantle the concrete, ensuring the
durability of the structure.
• Due to the minimized generation of noise, dust, and other
complaints, it can be applied in all areas, including urban
centers.
• Expansion & contraction and rotation in all directions
(longitudinal, transversal, and vertical)
• Full waterproof function
• Customized design
• Installation in all types of bridges
• Elastic parts with excellent load attenuation
• Approved high-quality materials
3. Waterproof
For the implementation of the perfect waterproof function of
expansion joints, waterproof rubber seals are put in the rail
grooves processed in the same way of rubber seals. So, water leak
is perfectly prevented. It is easy to assemble and repair the
diamond-shaped waterproof rubber seals that have the excellent
function to prevent water from leaking to the bottom of an
expansion joint.
4. Anti-corrosion
As for the surface treatment of structural steels, hot dip
galvanizing is applied to prevent salt stress and corrosion in
accordance with KS D 8308 Standards. Compared to coating, this
treatment guarantees excellent corrosion-resistance and adhesion.
The thickness is 85μm, ensuring about 45 years of
endurance.
