    SYFR

    • Type : Complex finger rail structure
    • Connection & load transmission: Understructure consists of studded anchors that connect to skewed iron bars in slabs for load dispersion.
    • Durability & safety: The upper sides of the fittings have a wider contacting surface with wheels, decreasing the shock to 1/10 that of the rail joints for better durability and safety.
    • Waterproofing: A rubber seal is inserted in rail grooves for better waterproofing quality.
    • Mobility: Wheels make constant contact with the rail surface, and makes less noise and shock.
    • Unit length of product
      • Upper fingers: 1~2m, in shape of fingers
      • Lower fingers: In the shape of rails, with the same length as the width of the road
    • Maintenance/repair: Upper finger plates are replaceable for easy maintenance and repairs

    SYCF

    • Type : The upper part consists of middle fingers, along with edge fingers on either sides; and the lower part is a complex structure with one middle rail and a hollow box.
    • Connection & load transmission: The upper part has edge fingers that are connected with edge rails of the lower part by high strength bolts; hollow boxes and anchor hoops are connected to iron bars in the slabs for load dispersion.
    • Durability & safety: Upper edge fingers have wider contact area with wheels for stress dispersion, guaranteeing high durability and safety.
    • Waterproofing: The rubber seal is compressed between fingers and rails connected by bolts.
    • Mobility: Fingers of the upper parts prevent wheels from treading and making noises
    • Unit length of product
      • Upper edge fingers: 1~2m, finger shaped.
      • Lower rail: Same length as the width of the road
    • Maintenance/repair: Upper edge fingers are replaceable for easy repair

    SYIF

    • Type : Two finger-shaped metal bodies are connected to the lower rails by high strength bolts and studded anchors; the length of fingers changes with regular intervals
    • Connection & load transmission: The lower structure of the joint is connected to iron bars in the bridge slabs by angles and studded anchors for stress dispersion
    • Durability & safety: Fingers disperses stress from contacting surface of wheels; wave pattern in post-placing concrete enhances adhesion and prevents damages.
    • Waterproofing: The rubber seal consists of compressed fingers and rails connected with bolts, featuring superior waterproofing capacity
    • Mobility: SYIF makes less noise and provides superior mobility for vehicles
    • Unit length of product: Length of lower structure of expansion joint is same as the width of the bridge; upper fingers are 1~2m long.
    • Maintenance/repair: Upper edge fingers are replaceable for easy repair.

    SYR

    • Type : Steel rail and support bars
    • Connection & load transmission: Wing hooped lower structure is connected to iron bars in the slab for load transmission.
    • Durability & safety: SYR is made of steel for superior safety
    • Waterproofing: Rubber seal in the rail grooves for superior waterproofing
    • Mobility: Makes louder noise and greater shock in greater expansion movement (No. 100 and higher)
    • Unit length of product: Product length is the same as the road width, in transportable shape
    • Maintenance/repair: Full replacement after breaking the concrete layer

    SYCRMJ

    • Durability: Superior and semi-permanent durability due to steel upper part
    • Mobility: Driving surface is in round shape for less noise and superior mobility of vehicles; highly durable against shock by wheels and abrasion.
    • Constructability: Bolt type pre-setting devices are easily adjustable on-site according to temperature or the general condition of the premises
    • Maintenance and repair: Simple structure for easy construction; the SY-CRMJ is manufactured in 1.8m-long segments for rapid installation and economic maintenance & repair
    • Waterproofing: Special reinforcement between the segmented products for superior waterproofing
    • Sound absorption: Sound absorbing material in the SY-CRMJ dampens vibration and shock to the expansion joint caused by vehicle wheels, dampening noise and shock to the entire cross-section of the bridge

  • nejin_04_06.jpg

    SYCRFJ

    • Durability: Processed H-BEAM for semi-permanent lifecycle against shock and abrasion
    • Mobility: Minimal discontinuity for better smoothness and mobility. Bolt-type pre-setting devices are easily adjustable on-site according to the temperature or the general condition of the premises
    • Maintenance and repair: Simple structure for easy construction; the SY-CRMJ is manufactured in 1.9m-long segments for rapid installation and economical maintenance & repair
    • Waterproofing: Special reinforcement between the segmented products for superior waterproofing
    • Sound absorption: Sound absorbing material in the SY-CRFJ dampens vibration and shock to the expansion joints caused by vehicle wheels, dampening noise and shock to the entire cross-section of the bridge
    • Blocking of contaminants: The filling-material blocks out the introduction of large contaminants to gaps of the rail, preventing the loss of expansion movement.

    SYSTM

    • Overview: Improved version of the existing mono-cell and new mono-cell joints; upper surface of the rail joints are processed in the shape of mono-cells; All-in-one type, or custom-made type products (unit length: 1m) available for order; applicable to partial repairs.
    • Durability: Semi-permanent durability thanks to the same material as the rails
    • Mobility: Mono-cell patterns in the upper slabs guarantee superior vehicle mobility
    • Applicability: Same structure as rails: transverse and longitudinal installation possible; applicable to many types of bridges, including skewed bridges and curved bridges
    • Waterproofing: The rubber seal is assembled with the existing rail for perfect waterproofing; apron attached to the kerb.

    SYREAL

    • Slide balls to the fixed rail grooves for easy replacement of waterproof seals
    • Semi-permanent fixed rail
    • Longitudinal & transverse sections of slabs embraced
    • Fixed rails are embedded before depositing concrete; strict management of premises needed
    • Teeth on the outside of the fixed rail fix concrete.
