Abstract
The utility model belongs to the technical field of the expansion device and discloses a dustproof bridge expansion joint. The dustproof bridge expansion joint is mainly characterized by comprising profile steel edge beams arranged in a pair, wherein a water stop adhesive tape is arranged between the profile steel edge beams and a rubber dustproof plate with a high-strength rubber sponge element is arranged on the water stop adhesive tape. The dustproof type bridge expansion joint provided by the utility model is characterized in that the rubber dustproof plate and the water stop adhesive tape form two layers of waterproof and dustproof structures, when the water stop adhesive tape expands, the high-strength rubber sponge element and the rubber dustproof plate also expand simultaneously, and when the high-strength rubber sponge element expands to generate elasticity, impurities such as stone accumulated on the rubber dustproof plate can be popped up and the water stop adhesive has small possibility of falling and is difficult to damage, therefore, the dustproof type bridge expansion joint is good in applying effect and long in service life.
