■ It is easy to manufacture and maintain / repair by fastening upper and lower plate with high tensile bolt, and it
can interlock with lower plate and it is easy to adjust the flow rate according to displacement of expansion and
contraction amount.
■ Aluminum alloy (A6061-T6) is used for the running surface of the vehicle, which is excellent in durability and
flatness, and has a structure for improving sliding resistance.
■ It is superior in durability by using aluminum material, which can fundamentally prevent after concrete damage
which occupied the highest frequency of breakage of the conventional expansion joint device, and can be
controlled and replaced immediately when the problem arises due to expansion / contraction displacement. |
