Adjustable finger joint
Patent No. 10-2041736
Expansion joint
Technical overview
When the oil gap due to shift lateral flow, abnormal temperature and other abnormal behaviors can lead to loss of function of the expansion joint due to a collision of the expansion joint and an accident of the driving vehicle, a new joint is developed to respond to this.
With the new construction amount adjustment system, it is possible to secure additional new construction with a simple operation in the event of a shortage of new construction.
When the expansion joint due to the lateral flow of the bridge is collided by the collision avoidance system, it absorbs the additional displacement equivalent to the external impact to prevent damage to the upper girder and the expansion joint.
Technical features
Securing additional expansion amount of 20mm~40mm or more by applying the expansion amount variable control system
By applying the collision avoidance system, the collision energy of the expansion joint due to girder constriction is converted into horizontal displacement energy of the expansion joint to absorb the collision displacement and maintain the function of the expansion joint.
7-fold waterproof system + clamp device + rubber seal pressure plate to secure perfect waterproof performance.
Simple rubber seal replacement and self-cleaning function of hump-type waterproof rubber induces smooth discharge of foreign substances.
