Expansion Joint
Explanation
에너지흡수 성능이 우수한 저항복점 강재를 심재로 사용하여 강재의 탄/소성에 의한 지진에너지 소산과, 심재가 압축시에 좌굴하는 것을 구속하기 위해 ㄷ형 채널강재로 보강한 강재형 제진장치
-
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
-
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.
